A movable platen according to the present invention includes: a mold clamping platen 42 having a projecting portion 62 in a mold closing direction-side surface; a mold mounting platen 44 mounted to the projecting portion 62 of the mold clamping paten 42; and a guide mechanism 50 fixed to the mold clamping paten 42 and supporting the mold mounting platen 44. Only the mold clamping paten 42 is fixed to the guide mechanism 50, while the mold mounting platen 44 is not fixed but placed on platen surface support portions 52.

An injection molding apparatus comprises a support base and a mold carrier removably mounted to the support base. The mold carrier includes a mounting plate with attachment features for engaging the support base. A mold with two mold plates is slidably mounted to the mounting 5 plate. A clamp is operable to move the plates between open and closed positions. In the closed position, the plates abut one another. In the open position, the plates are spaced apart for removing molded articles.

A fixed crank driving mechanism is provided, and belongs to the field of a crank driving mechanism, including a servo motor provided at one side of a fixed template, where the servo motor is in transmission connection with a rotating shaft, each end of two ends of the rotating shaft is connected with a crank, a tip end of the crank is movably connected with an elbow-shaped transmission arm, the elbow-shaped transmission arm is movably connected with a piston rod of an oil cylinder through a connecting seat, the connecting seat and the oil cylinder are fixedly provided on a movable template, the movable template is movable along guide posts, and one end of each of the guide posts is vertically and fixedly connected with the fixed template. The fixed crank driving mechanism reduces the weight of the movable template and the load of the servo motor.

A method for detachably attaching a linking unit, including an end with a hole and a slit, to a mold, the method comprising inserting a first attachment member connected to the mold through the hole; and inserting a second attachment member connected to the mold through the slit, wherein the linking unit is detached from the mold by moving the linking unit in a direction opposite to a direction in which the slit is formed in a state where the first attachment member is disconnected from the mold and the second attachment member remains connected to the mold.

A mold device of related art has a problem that a total volume of the device becomes large. In an example aspect of the present disclosure, a mold device includes a fixed mold base for supporting a fixed mold, a mobile mold base for supporting a mobile mold, a frame to which the fixed mold base is fixed, provided to extend in a direction in which the mobile mold base is moved, and formed into a wall shape, and holding means for movably supporting the mobile mold base to the frame. The frame is provided along at least one side of the mobile mold base except an upper surface thereof with the mold device installed, and the holding means support the mobile mold base at one side of the mobile mold base.

A toggle link clamping mechanism with a negative rear angle comprises a tail plate, a movable mold plate, and a toggle link mechanism. The toggle link mechanism comprises a thrust seat and a pair of link assemblies symmetrically distributed with one above the other. Each link assembly is composed of two independent front links, three independent rear links, and a small link, wherein front ends of the two front links are hinged to a rear face of the movable mold plate, rear ends of the two front links are hinged to front ends of the three rear links, rear ends of the three rear links are hinged to a front face of the tail plate, one end of the small link penetrates through a middle portion of the rear link in the middle and is hinged to the middle portion of the rear link in the middle.

In a mould-closing unit (F) for an injection-moulding machine for processing plastics, at least one mould carrier (10), which can be moved in a longitudinal direction (L-L) of the mould-closing unit (F), is arranged on a machine base (14) and between itself and a further mould carrier (12) forms a mould-clamping space (C), in which parts of at least one cyclically openable and closable injection mould (M) can be received. At least one linear guide (16), arranged in the longitudinal direction (L-L) on the machine base (14), serves for guiding the at least one movable mould carrier (10) when there is movement in the longitudinal direction (L-L). The mould carrier is supported on the machine base (14) and/or the at least one linear guide (16) by way of a load take-up (18), which has above the at least one linear guide (16) an articulating region (20) for the at least one movable mould carrier (10), which region is connected to the movable mould carrier with a force fit or material bonding and the stiffness of which is greater in the longitudinal direction (L-L) than in a direction transverse to the longitudinal direction (L-L). The forces acting on the guide of the movable mould carrier during the operation of the injection-moulding machine are minimized by the load take-up (18) and/or the articulating region (20) being elliptical in cross section, with the minor axis of the ellipse extending in a direction transverse to the longitudinal direction (L-L) of the mould-closing unit (F).

A mold clamping apparatus includes a mold clamping mechanism having a screw shaft, a crosshead, and a cylindrical cover member configured to house the screw shaft. The cover member includes a rear cover member arranged between a mold clamping housing and the crosshead and a front cover member arranged between the crosshead and a movable platen, and the rear cover member expands and contracts in accordance with change in a facing distance between the mold clamping housing and the crosshead caused by movement of the crosshead.

Provided are an apparatus and a method for forming interior material of a vehicle, in which when a resin is injected onto a rear surface of fabric through a fixed mold while a moving mold, onto which the fabric is placed, is pressed against the fixed mold and then a core mold of the moving mold is pulled back by a decompression releasing distance, a capacity increases by as much as the distance such that a pressure and a temperature are reduced so as to minimize damage to the fabric.
