The ejecting mechanism can not only eject the product, but also take into account the discharge waterway, so that the product can be cooled better, plastic is saved, and the production cost is reduced.

Description

Ejector

【Technical field】

The invention relates to an ejection mechanism for ejecting products.

【Background technique】

In mold production, when the product is a transparent part, in order to ensure the appearance of the product, there should be no ejector print on the product, and in order to eject the product when the mold is opened, an auxiliary flow channel will be designed to assist the ejection of the product. Please refer to FIG. 1 , which shows a schematic view of the existing ejection mechanism. In the existing ejection mechanism, an auxiliary flow channel 2 is designed around the product 1, and a number of ejector pins 3 are arranged on the auxiliary flow channel 2. After the mold is opened, the ejector pins 3 eject the product under the action of the ejecting force of the machine. 1 eject the mold.

However, when the auxiliary flow channel is used to eject the product, the cooling time of the product is longer, the product is easily deformed, and the amount of plastic is increased, the plastic is wasted, and the production cost is increased.

In view of this, it is necessary to develop an ejection mechanism, which can not only eject the product, but also take into account the discharge waterway, so that the product can be cooled better, and the plastic is saved, and the production cost is reduced.

【Content of invention】

Therefore, the purpose of the present invention is to provide an ejection mechanism, which can not only eject the product, but also take into account the discharge waterway, so that the product can be cooled better, save plastic, and reduce production costs.

The ejector mechanism of the present invention is applied in a mold, and the ejector mechanism includes:

upper roof;

a lower top plate, which is connected to the above-mentioned upper top plate, and a waterway and an O-ring are arranged in the lower top plate;

The inlet, whose activities are set in the male core of the mold, and is in contact with the product, has a slope on both sides of the inlet, and a waterway is also provided in the inlet;

One end of the top block is set in the above-mentioned inlet, and the other end is set in the above-mentioned upper top plate, and a water channel and an O-ring are also arranged in the top block.

Preferably, one end of the above-mentioned top block disposed on the insert is also provided with threads.

Compared with the prior art, the ejection mechanism of the present invention has a simple structure, is convenient for processing, has a better cooling effect on products, and saves costs.

【Description of drawings】

FIG. 1 shows a schematic diagram of a conventional ejection mechanism.

Fig. 2 is a schematic diagram showing the clamping state of the ejector mechanism of the present invention.

【Detailed ways】

See also shown in Fig. 2, ejection mechanism of the present invention, it is applied in the mould, and this ejection mechanism comprises:

upper top plate 40;

A lower top plate 50, which is connected to the above-mentioned upper top plate 40, and a first waterway 51 is also provided in the lower top plate 50, and an O-ring 22 is provided to prevent water seepage;

Insert 10, its activity is set in the male mold core 30 of the mould, and is in contact with the product 1, and is used to form the product 1. The two sides of the insert 10 are respectively sloped to ensure that it is in the male mold core 30 of the mould. The movement is smooth, and a second waterway 11 is also provided in the inlet 10 to cool the product 1;

Jack block 20, one end of which is set in the above-mentioned inlet 10, and is provided with threads, so that it can be more closely connected with the inlet 10, and the other end of the jack block 20 is arranged in the above-mentioned upper top plate 40, and in the jack block 20, there is also a There is a third waterway 21. One end of the third waterway 21 is connected to the second waterway 11, and the other end is connected to the first waterway 51. An O-ring 22 is also provided in the top block 20 to prevent water seepage.

When the mold is closed, the first waterway 51, the second waterway 11, and the third waterway 21 form a circulation loop to cool the product 1; when the mold is opened, under the action of the mold opening force of the machine, the male mold of the mold The part is separated from the mother mold part, and then the ejector pin (not shown) of the machine platform gives an ejection force to the upper top plate 40 and the lower top plate 50 through the lower fixing plate 60 of the mold. Under the action of the ejection force, the upper top plate 40 drives the ejector block 20 and the inlet 10 move together towards the direction close to the mother template 70, and the product 1 is ejected.

Compared with the prior art, the new slider mechanism of the present invention has a simple structure and is easy to process. It can not only eject the product, but also take into account the discharge waterway, so that the product can be cooled better, and it saves plastic and reduces production costs.

Claims (2)
