摘要:
Le dispositif de séparation comprend : - un dispositif d'actionnement (8) mobile en translation selon un premier axe (A1) entre une position rétractée et une position de séparation, - un élément de séparation (28, 60) mobile en translation selon un deuxième axe (A2) entre une position rétractée et une position de séparation, - un dispositif de transfert (26) reliant le dispositif d'actionnement (8) et l'élément de séparation (28, 60). Le dispositif de transfert (26) comprend au moins deux maillons (46), mobiles en rotation l'un par rapport à l'autre et par rapport au dispositif d'actionnement (8) et à l'élément de séparation (28, 60), et un élément de guidage (36) recevant lesdits maillons (46), lesdits maillons étant déplacés selon une course de déplacement par le dispositif d'actionnement (8) et déplaçant l'élément de séparation (28, 60).
摘要:
A mold for manufacturing hemispherical sections for a golf ball includes a mold plate and a movable insert. The mold plate includes a first surface. The movable insert includes a second surface. The movable insert is connected to the mold plate. The first surface of the mold plate and the second surface of the movable insert may move relative to one another during molding of a hemispherical section for a golf ball.

Molded rubber objects may be molded and de-molded by defining both a desired final form for the molded rubber object and a tab extending from the final form of the molded rubber object using a cavity in a mold. Rubber pellets may be dispensed in predetermined amounts at desired location(s) within the cavity to provide the rubber needed to form the molded rubber object. Heat and pressure may be applied to the mold to cause the rubber pellets to fill the cavity defining both the desired final form of the molded rubber object and the tab. After the heat and pressure has been applied, a gripping device may grasp the tab and move the tab in a direction and with sufficient force to peel the rubber object from the mold cavity. If desired, the tab may be removed from the molded rubber object.

A mould system for a "resin transfer moulding" process is presented, a system in which the cavity of a workpiece (1) to be produced is fully enclosed circumferentially by a multi-part shaping mould (2) and this shaping mould (2) is enclosed in a sealed manner by an outer, at least two-part enveloping mould (7, 8). A method for consolidating a fibre composite component with this mould system is also presented. And a method for producing a fibre composite component on the basis of the RTM process is shown, a method in which the intermediate space between a shaping mould (2) and a surrounding enveloping mould (7, 8) is filled with resin during the resin injection, after the curing the resin initially remains on the shaping mould (2) as a resin body but is destroyed during the demoulding of the workpiece (1), preferably at predetermined breaking points, and thus the demoulding of the workpiece (1) from the shaping mould (2) is assisted.
摘要:
A tube main body (12) of a curved tube (10) has a flow path following an axis line (12A), and includes a bent portion (14) at one portion in a direction along the axis line (12A). Also, in an inner periphery (14A) inside a bending direction of the bent portion (14) in the tube main body (12), a concave portion (16) is formed as an enlarged cross-section portion along a direction of the axis line (12A). Incidentally, in an inner die of a die for forming a curved tube, a hinge core forming the concave portion (16) is inserted in a groove portion of a main core, and the main core moves in a retraction-positional direction, so that a tip portion of the hinge core having a shape engaging with the inner periphery (14A) inside the bending direction of the bent portion (14) swings to a formation position of the main core.
摘要:
The invention relates to a device for producing a component made from a fibre composite material from a semifinished fibrous product by means of a multipart moulding and infiltration tool with tool parts, the moulding functional surfaces thereof forming, when the tool is closed, a cavity that defines the component. The device is characterized in that the tool (1) has a sealing frame (2, 16, 18, 20, 21, 22) which is designed as a hollow body and in which the semifinished fibrous product (3) can be arranged, and the tool parts (4) are configured and can be associated with the sealing frame (2, 16, 18, 20, 21, 22) such that, when the tool (1) is closed, the tool parts (4) are connected tightly to the sealing frame (2, 16, 18, 20, 21, 22).
摘要:
The invention relates to a tool for producing a fiber/plastic composite component (300), in particular for producing a carbon fiber-reinforced plastic component, comprising at least one first tool part (110) and at least one second tool part which can be moved relative to each other in order to open and close the tool (100) and which are formed with corresponding shaping regions (111) in order to form a cavity. At least one of the tool parts (110) is formed with at least one ventilating bore (115) in the shaping region (111), and a longitudinally movable pin (150) is arranged in the bore in order to open and close a ventilation line (140) which opens into the ventilation bore (115), said pin (150) also being designed as an ejector in order to remove a produced component (300)
摘要:
Touch fastener products, as well as apparatus and methods for manufacturing such products, are described. The methods and apparatus feature certain mold cavity shapes that are designed to facilitate demolding of hammer hook touch fastener elements exhibiting desirable fastening properties. Such mold cavity shapes can be combined with particularly soft molding resins to produce useful fastening products.
