Description

Plastic injection module embedding fixture structure

The present invention relates to the technical field of auxiliary tools related to plastic injection machines, in particular to a jig structure for embedding plastic injection modules.

The plastic injection molding process has been widely used in various product production lines. For example, in the manufacturing of shoe soles, different mold preset patterns can be used to quickly produce various shapes of finished shoe soles.

In the previous technology, although the soles produced by the injection molding process can achieve the effect of rapid production, the styles of the soles are all inked on the changes in the patterns, that is, the shape of the lines and the depth of the unevenness.

This is because to achieve a functional structure, such as the sole 80 of the claw 81 profile structure that increases the grip as shown in Figure 9, the mold must be matched by a female mold, a male mold and a plurality of sub-moulds.

The male and female molds are permanently installed in the plastic injection molding machine (previous technology), and the operator inserts the sub-moulds one by one in the preset position of the female mold, and then starts the plastic injection molding machine for injection molding, and removes the finished product after molding (together with the sub-mold), and separate the injection finished product from the sub-mold.

It is not difficult to find the following problems in the above operation process:

1. The plastic injection molding machine needs to wait for the operator to place the sub-moulds on the master mold one by one. Due to the interference and restrictions on the operator due to the installation angle and equipment height, etc., it will cause waste of man-hours for the operator and waste of plastic injection molding machine standby .

2. When the operator puts the sub-mould on the master mold with bare hands, the temperature is very unfriendly to the operator, and it is difficult to guarantee that it will not be scalded. And the operation process must endure the hardships and troubles of high temperature.

3. The operator needs to place his body and hands on the closing path of the plastic injection molding machine for a long time, which is also a safety hazard.

From the above problems, it can be found that how to quickly, accurately and conveniently insert complex sub-models into the master model is obviously necessary for improvement.

In view of the above-mentioned problems and deficiencies of the prior art, the main purpose of the present invention is to provide a fixture structure for inserting plastic injection modules, which solves the above-mentioned deficiencies of the prior art through innovative design of the structure.

According to the above-mentioned purpose of the present invention, a fixture structure for inserting plastic injection modules is provided, which provides a plurality of sub-moulds to accommodate, which includes a lower plate, a plurality of push rods, an upper plate, a plurality of limit posts, and a plurality of elastic parts . The lower board has a plurality of through holes. Each push rod is vertically arranged on the lower plate body. The upper plate has a plurality of sub-mold slots for accommodating the sub-mold and passing through the push rod. One end of each limit column is fixed on the upper plate body after passing through the through hole. Each elastic part is respectively sleeved on the outer peripheral side of each limit column, and pushes the upper and lower plate bodies. With the composition of the above components, the operator can quickly set the sub-mold in the plastic injection molding machine, improving production efficiency and safety.

In the following, please refer to the relevant drawings to further illustrate the embodiment of the jig structure of the plastic injection module embedded in the present invention. In order to facilitate the understanding of the implementation of the present invention, the same components are described below with the same symbols.

Please refer to Figures 1 to 6, the fixture structure of the plastic injection module of the present invention is matched with a master mold 91 (previous art) set in a plastic injection molding machine, and is used to combine multiple sub-moulds 92 (previous art) Technology) Quickly insert the master mold 91 into a preset position, which includes a lower board 10 , a plurality of push rods 20 , an upper board 30 , a plurality of limiting columns 40 , a plurality of elastic members 50 , and at least one positioning rod 60 .

The above-mentioned lower plate body 10 has a plurality of through holes 12 ; the through holes 12 are formed at predetermined positions through the lower plate body 10 at the top and bottom.

Each of the push rods 20 mentioned above is erected at a preset position of the lower plate body 10 .

The above-mentioned upper plate body 30 has a plurality of sub-mold slot holes 32 .

The sub-mold slot holes 32 are formed through the top and bottom of the upper plate body 30, and are step holes with large and small aperture sections 322,324. It also includes a surrounding portion 326 surrounding the outline of the large-aperture section 322 of the stepped hole. During implementation, the surrounding portion 326 of the large-diameter section 322 of each sub-mold slot 32 provides for the sub-mold 92 to accommodate, and the small-diameter section 324 allows the push rod 20 to selectively penetrate from the outside.

Above-mentioned each spacer post 40, one end has the limit that is greater than through hole 12 apertures. The bit head 42 is fixed on the upper plate body 30 after the other end passes through the matching through holes 12, and the upper plate body 30 is suspended above the lower plate body 10.

The above-mentioned elastic members 50 are respectively sleeved on the outer peripheral sides of each limiting column 40 , push the upper plate body 30 and the lower plate body 10 normally to separate them, and make each push rod 20 withdraw from each sub-mould slot hole 32 .
