Disclosed herein, amongst other things, are various conversion structures for use in a molding system (100, 200). A non-limiting embodiment of the conversion structure includes a standard mold receiver (140, 157) and a mold conversion module (151A, 151B, 151C, 251A, 251B, 251C, 251D, 251E, 251F, 152A, 152B, 152C, 170A, 170B, 170C). The standard mold receiver (140, 57) and the mold conversion module (151A, 151B, 151C, 251A, 251B, 251C, 251D, 251E, 251F, 152A, 152B, 152C, 170A, 170B, 170C) are configured to cooperate, wherein the mold conversion module (151A, 151B, 151C, 251A, 251B, 251C, 251D, 251E, 251F, 152A, 152B, 52C, 170A, 170B, 170C) is receivable in the standard mold receiver (140, 157) for converting a molding configuration of a mold (120).

The invention concerns an injection-moulding machine for processing plasticizable compounds, wherein a structural unit comprising at least the movable mould carrier (11), the stationary mould carrier (12) and the closure arrangement (13) of the mould-closure unit is supported on support elements (15) on the machine base. A pivot pin, about which the structural unit can be pivoted, extends transversely to the closure axis (s-s). Provided as the means for pivoting and displacing the structural unit is a drive unit (A) which is connected in articulated manner to the machine base (10) and to the structural unit at articulation point (21) which is at a spacing from the pivot pin (18). When the structural unit is moved from the horizontal position into the vertical position the drive unit (A) first pivots the structural unit and then also displaces it.

The invention is directed to a method for adapting injection molding machines utilizing horizontally opening and closing molds and their opening and closing mechanisms to vertically opening and closing molds and their opening and closing mechanisms and vice versa. An injection molding machine might, for example, be utilized to inject hot synthetic resin substantially horizontally into a cavity between horizontally opening and closing molds associated with horizontally opening and closing mechanisms. This horizontal mold and its opening and closing mechanism is removed relative to the injection molding machine and substituted therefor is a vertically opening and closing mold and its associated vertically opening and closing mechanisms. The hot plastic material from the horizontal injection molding machine is initially constrained in movement horizontally but subsequently vertically into the cavity of the vertically opening mold. This allows molds to be utilized with presses which might otherwise heretofore been structurally and functionally incompatible.

The present invention relates to a production method for a splash shield using a continuous extrusion-injection-foaming process, and more specifically relates to a method for producing a splash shield, in which method a base-portion raw material comprising a plastic, glass fibers, a compatibilizer and rubber is subjected to melt extrusion while at the same time injection molding is performed, and then, without removing the injection-molded article from the injection mold, the injection mold is rotated in the open state, and the injection-molded article is conveyed to a foaming mold and subsequently undergoes flame treatment and a polyurethane foam molding step. In the production method for a splash shield according to the present invention, a single process is used for the procedure in which the materials are separately compounded and pelletized and the procedure in which the injection-molded article is molded and a foamed body is molded, and thus it is possible to curtail the conveying of materials and various component parts and to reduce the risk of molding dimension errors and of denaturing and contamination in the conveying procedure.

A method for producing shape memory anti-counterfeiting identifier includes the following steps: a high polymer material with a shape memory function without the need of sunshine cross-linking or chemical cross-linking is directly extruded to become sheet in an extruder or is injected to be molded in an injection molding machine, and the extruded sheet can be a planar sheet or a sheet having a surface on which concave-convex patterns or characters are formed; the above sheet is then heated to the temperature higher than the vitrification temperature and lower than the melting point temperature, and the patterns or characters are pressed on the planar sheet, or the sheet on which the concave-convex patterns or characters are already formed is pressed to become planes or other patterns and characters; the sheet is then cut into small sheets, wherein one pattern or one group of characters is implied on every small sheet, and when the small sheets are again heated to the temperature higher than the vitrification temperature and lower than the melting point temperature, they will return to the extruded state.

The present invention pertains to a clamping device (2) that comprises: a fixed platen (5) which is configured such that a die can be attached thereto; a movable platen (7) which moves closer towards or away from the fixed platen (5); and a rotary platen (4) which is disposed so as to face a surface of the movable platen (7) on the side of the fixed platen (5) and which is configured such that a die can be attached thereto. A a cylindrical protrusion (28) is fixedly installed on the surface of the movable platen (7) on the side of the fixed platen (5). The rotary platen (4) is rotatably connected to said protrusion (28) via a bearing structure (36).
