摘要:
A net-shaped composite plenum housing body for a differential assembly having a pump is disclosed. The plenum housing body can include a low pressure inlet and a high pressure outlet configured to receive a control valve. The plenum housing body can also define a fluid inlet channel in fluid communication with the low pressure inlet via a first internal port and can be configured to be in fluid communication with an inlet side of the pump when the plenum housing body is assembled onto the differential assembly. The plenum housing body can also define a fluid outlet channel in fluid communication with the high pressure outlet via a second internal port and can be configured to be in fluid communication with an outlet side of the pump when the plenum housing body is assembled onto the differential assembly. The plenum housing body can also be formed as a net-shape fiber reinforced plastic material including chopped fibers, for example, chopped fiberglass fibers, and an epoxy resin.
摘要:
A respiratory nosepiece (10) and method of manufacturing the respiratory nosepiece, the respiratory nosepiece including a first nasal prong (110) with a first channel (112) extending there through, and a first side port (130) connectable to tubes (192, 194) having different first and second diameters. The first side port has a second channel (131) extending there through and in communication with the first channel. The second channel includes a first section (134) having the first diameter, a second section (136) having the second diameter, a first step (135) between the first and second sections, and a second step (137) between the second section and an end (133) of the second channel. The first and second channels are formed during injection molding by pins (412, 422, 431, 441) having flat pin-on-pin geometry to reduce resin flash within the channels.

The present invention relates to a method for the injection-moulding of plastics in order to produce tubular steam-conveying elements, comprising a step involving provision of at least one mould (B) shaped for forming of a tubular element (1;1a), a step involving insertion of a male element (C) the mould (B), a step involving retention of the male element (C) inside the mould (B) by means of clamping means (E) mechanically associated with the mould (B); a step involving injection of plastic into the mould (B) in order to obtain a tubular conveying element (1;1a), a step involving removal of the clamping means (E), a step involving extraction of the male element (C) and a step involving removal of the tubular element (1;1a) from the mould (B). The step involving removal of the clamping means takes place during the injection step when the plastic is in the vicinity of or in contact with the clamping means (E). This moulding method envisages that the mould (B) is shaped for the forming of a tubular element (1;1a) comprising an outer shell (5) and an inner pipe (6). At least part of the outer shell (5) is provided with a finned surface which defines a plurality of channels (20) through which the clamping means (E) act so as to grip the male element (C) during the retention step, being inserted into holes (F) provided on the mould at the bottom of the channels (20).

Es werden ein Verfahren und eine Vorrichtung zum Spritzgießen eines kastenförmigen Behälters aus Kunststoff angegeben, in dessen Wandung senkrecht zu seiner Standfläche verlaufende Hohlräume angebracht sind. Zur Formung der Hohlräume sind in der Vorrichtung langgestreckte Holme (9) angebracht, die zur Stabilisierung ihrer Lage durch in ihrer Längsrichtung bewegbare Stifte (11) abgestützt werden. Damit im fertigen Behälter keine Löcher vorhanden sind, werden die Stifte (11) während des Spritzvorgangs nach Maßgabe des in ihrem Bereich anstehenden, sich in Abhängigkeit vom Füllstand des Kunststoffs ändernden Spritzdrucks so weit von den Holmen (9) weggezogen, bis ihre Stirnfläche mit der Oberfläche des Teils der Vorrichtung, aus der sie herausragen, fluchtet.

A catheter includes: a catheter shaft; and a hub on a proximal side of the catheter shaft. The catheter shaft includes a shaft inner surface inclined portion at a proximal portion, the diameter of which increases proximally such that the shaft inner surface inclined portion forms an angle with the catheter central axis. The hub includes a first hub inner surface inclined portion continuous from the shaft inner surface inclined portion and inclined at the same inclination angle as the shaft inner surface inclined portion, and a second hub inner surface inclined portion proximal of the first hub inner surface inclined portion. The second hub inner surface inclined portion inclination angle differs from the first hub inner surface inclined portion inclination angle. The hub does not cover an inner peripheral surface of the catheter shaft in an interlock portion in which the catheter shaft and the hub are interlocked together.

The apparatus (1) for the injection moulding of containers in plastic material comprises a mould (2) having a female matrix die (3) and a corresponding male element (4) that can be coupled to one another, between the female matrix die (3) and the male element (4) being defined a forming inter-space (5) of at least a container, and at least a centring stem (10) for centring the male element (4) with respect to the female matrix die (3), which comprises a first extremity (12) having a locator surface (12a) for the male element (4), is sliding along a sliding direction (D) substantially transversal with respect to the male element (4) inside a corresponding centring hole (11) obtained in the female matrix die (3), and is mobile with reciprocating motion between a backward configuration, in which the locator surface (12a) is substantially arranged in correspondence to the inner surface of the female matrix die (3), and a forward configuration, in which the locator surface (12a) is up fast on the male element (4), the first extremity (12) of the centring stem (10) having a cross section substantially decreasing towards the locator surface (12a).
摘要:
The disclosed subject matter is directed to an injection mold and a method of injection molding having a molding core system in accordance with the disclosed subject matter. The molding core system comprising a plurality of co-operable components manipulable between a first molding position at which the core system is fully deployed and a second position in which the core system is configured to axially retract and radially contract into a second drawing position, the outer shape of said core system being substantially complementary to the inner shape of the molded article.
摘要:
A terminal for a battery has a mounting section and a contacting section. There is a torque ring between the mounting section and the contacting section. The mounting section is for holding the terminal within a battery cover, into which it preferably is injection molded. The terminal is a hollow body, which has an outer wall and an inner wall. At the contacting section, the outer wall is conically shaped. At the mounting section, the outer wall has at least one labyrinth ring forming a labyrinth. The inner wall comprises at least two sections. An upper section is essentially surrounded by the contacting section, and preferably has a conical shape. A lower section is essentially surrounded by the mounting section. The lower section preferably has in a lateral sectional view a concave shape. Between the upper section and the lower section, there is an edge. The edge at the inner wall is essentially surrounded by the torque ring at the outer wall.
