Although the hydraulic and electric distribution technology can meet the requirements of the existing disc type forming technology, the related mechanical parts are easy to generate the maintenance requirement under the use of high hydraulic pressure and large current, so that the hydraulic and electric distribution technology is still not good for industrial application.

Disclosure of Invention

The present invention has been made in view of the above problems, and it is an object of the present invention to provide a system for molding a non-foamed material, which can reduce the occurrence of damage to parts by changing the position of a mold, which has not yet been molded with the non-foamed material, by a rotating mechanism such as a disk, while performing molding of the non-foamed material with a processing device having a plurality of mold stations.

The invention adopts the following technical scheme to achieve the purpose:

a shaping system for non-foam material is composed of multiple mould clamping mechanisms for clamping mould and applying force to mould, and a ring-shaped carrier for said rotary mechanism, which is fixed to the fixed position of said mould clamping mechanisms and moving between said mould clamping mechanisms.

Furthermore, the non-foam material molding system includes a non-foam material molding method using the article, in addition to the article with the above technical features, the method includes a mold locking step, a mold releasing step, a material injecting step and a mold moving step, wherein:

the mould locking step makes all or part of the mould clamping mechanisms respectively positioned at a mould locking position, and can respectively apply the mould locking force to all or part of the moulds, the mould releasing step makes the mould clamping mechanisms respectively positioned at a mould releasing position so as to release the mould locking force respectively applied to the moulds in the mould locking step, the material injecting step supplies non-foaming formed high molecular raw materials to the moulds positioned at a default material injecting position by a raw material supply unit, and the mould moving step rotates the carrying piece after the mould releasing step is implemented so as to drive the moulds to change the positions of the moulds;

and the steps are circularly implemented in sequence according to the sequence of the mold locking step, the mold releasing step and the mold moving step, the material injecting step is only positioned on the material injecting position and is locked by the mold locking force provided by the mold locking step, the raw material is provided by the raw material supply unit, and the mold is still kept in a mold closing state when the mold locking force is released by the mold releasing step, so that the received raw material is stored in a mold chamber space inside the mold, and then the raw material is moved to other mold clamping mechanisms through the mold moving step and is applied with the mold locking force exerted again, therefore, the molds are respectively subjected to the mold releasing step, the mold moving step and the mold locking step which are respectively carried out for multiple times before the process that the raw material supplied by the raw material supply unit is subjected to the mold molding in the mold chambers of the molds is finished.

Detailed Description

A preferred embodiment of the present invention is described below with reference to the drawings.

Referring to fig. 1 to 3, in a non-foaming material forming system according to a preferred embodiment of the present invention, a non-foaming material forming apparatus 10 mainly includes a rotating mechanism 20, a plurality of first to sixteenth mold stations S1 to S16, a plurality of mold clamping mechanisms 30, a plurality of mold lifting mechanisms 40, and a material supply unit 50.

The rotating mechanism 20 is a conventional one, and has a circular plate-shaped carrier 21, which is disposed at a fixed location by a known technique, and the carrier 21 can rotate around a virtual main axis a, which is located at the center of the circular shape of the carrier 21 in this embodiment.

The mold stations S1-S16 are respectively arranged in sequence with equal angular intervals and radiation around the main axis a and are respectively fixed on the respective addresses, the mold clamping mechanisms 30 are sequentially fixed on the first mold station S1 to the twelfth mold station S12 within the range of 270 degrees around the main axis a, and the mold lifting mechanisms 40 are sequentially fixed on the thirteenth mold station S13 to the sixteenth mold station S16.

Each mold clamping mechanism 30 is a conventional mechanism for providing mold clamping force to the mold and performing heat exchange with the mold, and has a frame 31 straddling the carrier 21 and a clamping portion 32 slidably disposed on the frame 31, wherein the frame 31 positions the pair of inner columns 311 inside the inner ring side of the carrier 21 and the pair of outer columns 312 outside the outer ring side of the carrier 21, so that the rotation of the carrier 21 is not blocked by the frame 31.

Each mold opening mechanism 40 is conventional for opening a mold.

The raw material supply unit 50 is fixed to a material injection position adjacent to the first mold station S1 in this embodiment, taking a conventional injection molding machine as an example, so as to supply the polymer raw material into the mold located at the first mold station S1, but it can be used in other known raw material supply technologies such as an extruder or an extruder.

The non-foaming material forming apparatus 10 is similar to the conventional disc type injection molding technique in structure, but the technique of fixing each of the clamping mechanism 30, the lifting mechanism 40 and the raw material supply unit 50 at their respective addresses without moving them is different from the prior art, and the movable portion of the non-foaming material forming apparatus 10 is limited to the rotation mechanism 20 as a main part, and accordingly, since the rotating mechanism 20, when functioning as a transporting assembly for carrying the mold, does not need to provide pressure or heat to the mold, therefore, it is not necessary to additionally arrange a rotatable distributor as in the conventional disk type injection molding technology, therefore, besides simplifying the structure of the non-foaming material forming device 10 and reducing the probability of part damage, the molding apparatus 10 using the non-foamed material can be advantageously applied to a processing method as described below.

As shown in fig. 4 to 6, the non-foam material molding system further includes a mold locking step, a mold releasing step, a material injecting step, and a mold moving step in addition to the non-foam material molding device 10, wherein the mold locking step is as shown in fig. 4, when a plurality of molds 60 fixed on the carrier 21 are moved to each of the mold clamping mechanisms 30, the clamping portion 32 of each mold clamping mechanism 30 is moved toward the horizontal plane of the carrier 21, so as to apply a mold locking force to the molds 60 that have been closed, so as to resist the internal pressure of the molds 60 and ensure the mold closing of the molds 60.

In the mold releasing step, as shown in fig. 5, the clamping part 32 of each clamping mechanism 30 is moved away from the horizontal plane of the carrier 21, so as to release the clamping force applied to the mold 60 in the mold clamping step, and in this step, the mold 60 is held in the clamped state by gravity only.

The mold moving step is shown in fig. 6, and drives the carrier 21 to rotate around the main axis a by external force, so as to drive each mold 60 to change the position of the mold station.

The injection step is to supply the polymer material to the mold located at the first mold station by the material supply unit 50.

Referring to fig. 2, the non-foamed material molding system is implemented by moving the molds to the fixing positions of the mold stations S1 to S16, respectively, in the mold moving step, and then applying the mold clamping force to the molds corresponding to the mold clamping mechanisms 30.

While the clamping force is continuously applied, the mold located in the first mold station S1 receives the polymer raw material supplied from the raw material supply unit 50; in the second die station S2 to the twelfth die station S12, the dies respectively perform molding processing of molding the polymer raw material existing inside the dies; the molds in the thirteenth mold station S13 to the sixteenth mold station S16 can be opened by the mold lifting mechanisms 40, so as to perform the processes of removing the molded product and cleaning the mold.

When the preset clamping force application time is up, the mold releasing step is carried out immediately to release the clamping force applied to the molds, so that the molds are returned to the state of maintaining the self-clamping state of the molds only by means of gravity, and meanwhile, if the internal pressure in the molds is too high due to the generation of gas, the molds can be released from the mold piece combination part or the preset exhaust part of the molds, so that the exhaust effect is achieved.

And after releasing the mold clamping force applied to the mold by the mold clamping mechanisms in the mold releasing step, the mold moving step is immediately performed to move the mold which has received the raw material in the first mold station S1 to the second mold station S2, and simultaneously move the empty mold which has been cleaned in the sixteenth mold station S16 to the first mold station S1, so that the material injection step can be performed in the mold clamping step which is performed subsequently.

The plurality of molds of the non-foaming material molding system can receive the raw material while sequentially passing through the first mold station S1, and in the moving process of the subsequent mold station, the mold locking step, the mold releasing step and the mold moving step are cyclically performed, and the exhaust is performed under the alternate implementation of the mold locking and the mold releasing, for example, the time for applying the mold locking force can be maintained at 30 seconds, and the time for implementing the mold releasing step and the mold moving step is preset to 7 seconds, so as to complete the molding of the high molecular material by the molds.
