Description

An anti-blocking and anti-trapped air device for the front mold core of a plastic mold

technical field

The utility model relates to an anti-blocking and anti-trapped gas device for the front mold core of a plastic mold.

Background technique

Existing plastic molds generally choose to make the back mold when making the bone position, because if the bone position is relatively deep, if it is made in the front mold, it will easily cause the front mold to get stuck. Existing plastic molds often change the product or change the parting surface in order to prevent the phenomenon of front mold jamming to avoid this phenomenon. This change will bring a lot of inconvenience and increase costs to production, and there are still a large number of products that cannot be adjusted above, and have to make deeper bone positions in the front mold. Therefore, the problem of the previous mold card still needs to be solved.

Utility model content

The purpose of this utility model is to overcome the deficiencies in the prior art, to provide a simple structure, which can effectively solve the plastic mold stuck front mold, ensure a good exhaust effect, so that the product will not appear scorched or lack of glue. Anti-blocking and anti-trapped air devices for the front mold core of the plastic mold.

In order to achieve the above object, the utility model adopts the following scheme:

An anti-blocking and anti-trapped air device for the front mold of a plastic mold, comprising a front mold and a rear mold, a cavity is formed between the front mold and the rear mold, and it is characterized in that: on the front mold An installation groove is provided, and an ejection device that can push the product out of the front mold to prevent the product from being stuck to the front mold and generate trapped air when the mold is opened is provided in the installation groove.

The above-mentioned anti-jamming and anti-trapped air device for the front mold core of a plastic mold is characterized in that the pop-up device includes a bone insert that is movably arranged in the installation groove, and the bone insert An elastic piece is arranged between the piece and the bottom of the installation groove.

The anti-jamming and anti-trapped air device for the front core of a plastic mold as described above is characterized in that the elastic member is a spring.

The above-mentioned anti-jamming and anti-trapped air device for the front core of a plastic mold is characterized in that the elastic member is a shrapnel.

The above-mentioned anti-blocking and anti-trapped air device for the front mold of a plastic mold is characterized in that the front mold is fixedly connected to a certain template, and a runner plate is arranged on the fixed template. The above-mentioned flow channel plate is provided with a fixed mold bottom plate.

The anti-jamming and air trapping device for the front mold core of a plastic mold as described above is characterized in that the rear mold is fixedly connected to the movable template.

In summary, the utility model has the beneficial effects relative to the prior art as follows:

The utility model has a simple structure, can effectively solve the problem that the plastic mold is stuck in the front mold, ensures a good exhaust effect, and prevents the phenomenon of scorching and lack of glue in the product.

Detailed ways

The utility model will be further described below in conjunction with the accompanying drawings and specific embodiments:

As shown in Figures 1 to 5, a plastic mold front mold core anti-jamming and anti-trapped air device includes a front mold 1 and a rear mold 2, and a cavity is formed between the front mold 1 and the rear mold 2. 3. An installation groove 4 is provided on the front mold 1, and the product can be ejected out of the front mold 1 when the mold is opened in the installation groove 4, so as to prevent the product from being stuck to the front mold 1 and ejecting trapped air device 5.

The pop-up device 5 described in the utility model includes a bone insert 51 movably arranged in the installation groove 4 , and an elastic member 52 is provided between the bone insert 51 and the bottom of the installation groove 4 .

The first embodiment of the elastic member 52 described in the utility model is a spring. The second embodiment of the elastic member 52 described in the utility model is a shrapnel.

The front mold 1 described in the utility model is fixedly connected on a certain formwork 6, a flow channel plate 7 is arranged on the said fixed formwork 6, and a fixed mold bottom plate 8 is arranged on the said flow channel plate 7. The rear mold 2 is fixedly connected to the movable template 9 .

The plastic mold has one mold and one cavity, and the front mold has relatively deep bones that need to be used as inserts. However, this structure is easy to move upwards with the front mold when the mold is opened, causing the product to get stuck on the front mold. Make an elastic piece at the bottom of the bone insert. When the front mold is opened, the elastic piece will pop the bone insert towards the parting surface, so that the bone part of the front mold is completely separated from the front mold. An action to assist the ejection of the bone position so that it will not be stuck in the front mold, so that the product can be ejected smoothly without being stuck in the front mold. Many products that need to be used as front mold inserts can use this structure, which can completely solve the problem. The problem of stuck front mold and trapped air.
