Description

Pressurization device {PRESSURE DEVICE}

The present invention relates to a pressurizing device, and more particularly, to a pressurizing device implemented to press-mold a workpiece by pressing a mold, which is a basic frame of molding, downward.

An injection molding machine or a press machine (hereinafter referred to as a 'molding press device') uses a molding space formed between an upper mold and a lower mold to perform press work such as drawing, bending, cutting, or injection. Perform molding operations.

The molding press apparatus must open or close the molding space on a regular basis. To this end, a conveying means for conveying the slide member having the upper mold fixed thereto, and pressing the upper mold toward the lower mold to facilitate the molding operation. Pressing means for pressurizing are required.

For example, a conventional molding press apparatus includes a slide member comprising a plurality of guide rods installed in parallel at a predetermined interval, an upper fixing plate installed at an upper end of the guide rod, and a lower fixing plate provided at a lower end of the guide rod.

The slide member is installed between the upper fixing plate and the lower fixing plate, and is installed to be movable up and down by a frame made up of an intermediate fixing plate through which a plurality of guide rods penetrate, and a plurality of supporting bars supporting the intermediate fixing plate at a predetermined height from the ground. .

An upper mold is installed on a lower surface of the upper fixing plate, and a lower mold is installed on an upper surface of the intermediate fixing plate fixed to the frame. Therefore, a molding space is formed between the upper mold and the lower mold.

A high speed transfer cylinder is installed between the intermediate fixing plate and the lower fixing plate as a transfer means for transferring the slide member at high speed. In addition, a pressure cylinder is installed on a lower surface of the intermediate fixing plate as pressing means for pressing the slide member to press the upper mold toward the lower mold.

Accordingly, in the related art, the rod of the pressure cylinder may be fixed or released using the clamp. For example, when the slide member moves up and down according to the action of the high speed transfer cylinder, the clamp is released to allow the rod to move freely. On the contrary, when pressing the upper mold toward the lower mold, by tightening the clamp to fix the rod of the pressure cylinder, the rod of the pressure cylinder is supported to press the slide member downward.

However, the conventional press device, after manufacturing the first processed product, the collected second processed product must be collected and transported to the second press device, so that the work is very cumbersome and the time required for the production of the product increases This occurred.

In addition, there is a problem that the manufacturing cost of the mold can be increased because the thickness of the mold cannot be increased because the detachment for fastening the mold or the workpiece is not easy.

On the other hand, the background art described above is technical information possessed by the inventors for the derivation of the present invention or acquired in the derivation process of the present invention, and is not necessarily a publicly known technique disclosed to the general public before the application of the present invention. .
