A die face monitoring system may include an upper die having an upper die face and an upper die opening extending towards the upper die face. Similarly, a lower die may include a lower die face and a lower die opening extending towards the lower die face. The lower die face is arranged to confront the upper die face and form a concavity therebetween. Furthermore, a plurality of sensors are mounted on a press, with each sensor corresponding to each one of the upper and lower die openings. Each sensor emits a beam of light towards and receives a reflection from a target surface within the upper and lower die openings in order to calculate a distance thereto.

Provided is a mold opening/closing device that can prevent a ball screw shaft from reaching a risky speed while using a ball screw having a cantilever supporting structure. A mold clamping device according to the present invention is provided with: a ball screw having a ball screw shaft and a ball screw nut that meshes with the ball screw shaft; and a motor that drives the ball screw. One end of the ball screw shaft is supported by a fixation plate or a movable plate so as to be rotatable or non-rotatable, while being restricted in movement in an axial direction and thereby serving as a fixed end, and the other end thereof serves as a free end. Further, the mold clamping device is characterized in that a distance between the ball screw nut and the fixed end is shorter than a distance between the fixed plate and the movable plate.

A modular mold structure for expanding and sintering polystyrene, particularly for obtaining prefabricated panels with embedding elements, before sintering, includes a plurality of twinned sintering modules or adjacent twin molding units, each having an upper and a lower shell associated by a base, and a raised truss element supporting the upper shell through linear elevation movement and angular rotation movement members, while the truss base portion supports the lower shell preferably through sliding and guide members on the ground, shared by all twinned adjacent molding units, so that the lower shells can be displaced in a block at least on one side and preferably on two sides of the assembly of the upper shells, for displacement arrangement thereof, to be preferably loaded on one side with the a reinforcement system to be embedded in the panels and to be preferably unloaded on the other side of the finished reinforced panels.

The present invention relates to a mold drum for molding products from a mass of food starting material. The mold drum comprises one or more cavities with a mold cavity wall having at least partially a porous structure, whereas each cavity is connected to a passage. The present invention further relates to a cleaning apparatus for the inventive mold drum with supporting means for supporting the axis of the drum. Additionally, the present invention relates to a process for cleaning the inventive drum.

A mold clamping apparatus includes a mold clamping cylinder. The mold clamping cylinder has, in a region thereof located below left and right lower tie bars and above left and right sliders, a left grooved portion opened leftward and elongated horizontally, a right grooved portion opened rightward and elongated horizontally, and a leg portion formed between the left and right grooved portions. The leg portion and the left and right grooved portions together form a constricted part.

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.

In one embodiment, an apparatus and a method of manufacturing a paperboard tray therewith is provided. In particular, a hub is configured to rotate about a shaft. On the hub, a plurality of first molds are formed in the hub. Conversely, a plurality of second molds are each disposed above each of the plurality of first molds respectively and rotate above the first molds. In this configuration, the plurality of second molds are configured to move in unison with the plurality of first molds as the hub and second molds rotate and to move orthogonally towards and then away from the first molds as the second molds rotate.
