Description

A rubber part production mold that facilitates demolding

Technical field

The utility model relates to the technical field of rubber parts production molds, specifically a rubber parts production mold that is convenient for demoulding.

Background technique

Rubber parts refer to the activities of producing various rubber products using natural and synthetic rubber as raw materials, and also include rubber products regenerated from waste rubber. The output of synthetic rubber has greatly exceeded that of natural rubber. The largest output is styrene-butadiene rubber, and rubber parts require the use of molds during the production process and can be formed into various shapes.

For example, the authorization announcement number "CN211541993U" is called a rubber parts production mold. Although a screw rod is fixed through the top of the limit block, the screw rod penetrates the inside of the top plate, and a handle is fixed on the upper end of the screw rod. There is a mold cavity on the top of the lower mold and a cooling mechanism. The cooling air and cooling water inside the cooling water channel and the cooling air channel can have a double cooling effect on the lower mold, thereby speeding up the molding of rubber parts and improving Although the efficiency has been reduced, it still exists. In the existing rubber parts production mold, when the rubber parts are formed and processed inside the mold, the rubber itself is easily deformed by external factors. Therefore, after the rubber parts are produced inside the mold, the rubber parts will interact with the mold itself. The size and shape of the fit are completely consistent, so there is no gap between the mold and the rubber part. This makes it difficult for the rubber part to be taken out from the inside of the mold after production and processing, and ultimately causes the problem that the rubber part production mold is not easy to demould.

At the same time, the current rubber parts production mold uses manual twisting of the screw to push the mold downward to press the mold, but it can only be operated manually, which places certain requirements on the operator's technique and speed. If you are a novice The production and processing of rubber parts will lead to a certain position deviation during mold pressing, which ultimately affects the quality of the rubber mold produced by the rubber parts production mold.

Utility model content

Preferably, a positioning device is provided on the inside of the support frame;

The positioning device includes a guide rod, a collar and a first connecting block;

The two guide rods are fixedly connected to the inner side of the support frame. The outer sides of the two guide rods are slidably connected with collars. One side of the two collars is fixedly connected with a first connecting block. The other side of the collar is fixedly connected to a second connecting block. The lower end of the first connecting block is fixedly connected to a convex block. The top of the second connecting block is fixedly provided with a groove.

The utility model proposes a rubber part production mold that is easy to demould. The beneficial effect is that the rubber part production mold that is easy to demould is connected to an external power supply to start the air pump. The air pump will blow air through the inside of the air pipe of the air inlet box. When it is difficult to demould the rubber parts inside the lower mold, the air pipe blows the gas from the blowing end to between the rubber parts and the lower mold, and uses air pressure to push up the rubber parts. The other end of the air pipe is fixedly connected with a pressure relief valve. When the air pressure inside the gas pipe is too high, the pressure relief valve can be opened to relieve the pressure. External air blowing is used to push up the rubber parts that are difficult to demould. This finally solves the problem of difficult demolding of rubber parts production molds.

The collar will slide on the guide rod. When the hydraulic cylinder pushes the upper mold to move downward, the upper mold will drive the first connecting blocks on both sides to move downward. The first connecting block will move under the limit of the collar on the guide rod. Sliding, when the upper mold and the lower mold are brought together, the bumps on both sides will snap into the inside of the groove. The sliding of the guide rod and the collar is used to position and limit the movement of the upper mold to prevent the upper mold from deflecting during movement. Shifting the position ultimately improves the quality of rubber parts produced by rubber parts production molds that facilitate demolding.
