A mold clamping device includes two mold platens; a plurality of ball screw mechanisms connecting the mold platens to each other; and a plurality of servo motors configured to drive the respective ball screw mechanisms. Each of ball screws respectively configuring the plurality of ball screw mechanisms is provided with a cover which covers at least a part of the corresponding ball screw between the two mold platens.

A device for machining a plate-shaped workpiece for a motor vehicle comprises a lower tool with a holding region for the workpiece, and a folding element which has a holding region for the workpiece and which is movable relative to the lower tool. The folding element (40) can change from a first state into a second state and can thereby form a first cavity between the holding region of the folding element and the workpiece.

Provided is a structure in which an inserted article is easily inserted and a product is easily released from a die after molding. The structure includes a positioning mechanism which is vertically arranged on one split die, includes a positioning pin having a tapered distal end, and positions the inserted article by engaging the inserted article with the positioning pin, a stop mechanism that has a spring means assembled with the one split die and a stopper portion held by the spring means, and temporarily stops movement of the other split die when the other split die comes into contact with the stopper portion at the time of mold clamping, and a pressing mechanism that has a spring assembled with the other split die, a pusher pin, a spring assembled with the one split die, and a pusher pin, and elastically presses the inserted article by the pusher pin.

A mold having an upper, medial, and lower bodies with a composite peripheral wall define an inside cavity which may have a complex shape as for instance, with circular protrusions, circular depressions, and axially aligned cylinders. Pour holes are provided for introducing a molding compound into the mold while allowing air to exit the cavity. The medial body may be made of multiple portions. The upper body may be axially lifted off the medial body and the medial body may be laterally moved away from the molded object which enables removal of the complex molded part.

An assembly includes a first mold component defining a first portion of a mold cavity and a first slot. The first slot corresponds to a first portion of a retention channel. The assembly also includes a second mold component defining a second portion of the mold cavity and a second slot. The second slot corresponds to a second portion of the retention channel. The assembly also includes a connector having a cross-sectional shape corresponding to a cross-sectional shape of the retention channel. The connector has thermal expansion characteristics that are different from thermal expansion characteristics of the first and second mold components such that when the first and second mold components are in contact and the connector is inserted into the retention channel, heating the assembly causes differential thermal expansion of the connector and the mold components resulting in a clamping force between the mold components.

Provided are induction heating cells including pressure bladders used for supporting dies and methods of using these induction heating cells. A pressure bladder may be disposed between a die and a bolster of the cell. Even when the bolster is deformed during operation of the cell, the pressure bladder continues to provide uniform support to the die thereby preserving integrity of the die and prevents its cracking or braking. As such, the cell may be operated at a higher processing pressure inside the cavity formed by the die without further strengthening the bolster. The bolster is allowed to deform without compromising the integrity of the die. The deformation of the bolster is compensated by the shape change of the pressure bladder. The number and/or position of the bladders in the cell may depend on the shape of processed parts.

A method of molding a green tire having a first and second bead area is described herein, wherein the method includes the steps of: inserting a tire clamping device inside a tire bladder and then inserting the tire clamping device and the bladder into the green tire, aligning the outer surfaces of the tire clamping device into engagement with a respective bead area of the tire so that each tire bead area is clamped between a respective upper and a lower mold ring and the tire clamping device during cure. A tire clamping device includes an inner portion, and a plurality of segments connected to the inner portion, wherein the tire clamping device has a closed position wherein the plurality of segments together forms a first and second ring for engagement with the bead areas of the tire so clamp the bead areas between the clamping device and the mold rings during cure.

A sole having a foam layer and a film layer. The foam layer is formed by mixing material A and material B. After the release agent is sprayed on the film layer, the raw material is filled in the cavity of the mold for baking insulation. The AB mixed raw material has emulsification reaction and is foamed, and the mold is filled and prepared. The present invention has the beneficial effects that: the sole according is mainly suitable for the sole of a slipper, lighter and more comfortable; a film is formed on the outer surface of the foam layer, so that the surface of the finished product is smoother, more beautiful, and higher in yield rate; in the preparation process, a shaking mode technology is adopted to reduce the shortage of materials and dark bubbles in the product and also reduce the amount of bubbles in the product.

A mobile vulcanizing press including a bottom box and a top box, which can be arranged one above the other with material to be vulcanized in between. The bottom box and/or the top box has/have at least one first bolt receiving section, in which a tension bolt can be pivotally located and at least one detent point is located on the bottom box or the top box, such that a detent means of the tension bolt can engage in the at least one detent point in at least one predetermined pivoting position of the tension bolt.

Systems and methods are provided for compacting laminates. One embodiment is a method for compacting a laminate onto a surface of a forming tool. The method includes placing the laminate onto the forming tool, disposing a compaction device over the laminate, gripping the compaction device to the forming tool, compacting the laminate with a pressure foot of the compaction device, and removing the compaction device from the forming tool.
