Description

Technical Field

[0001] The utility model relates to the technical field of manufacturing devices, in particular to a rubber manufacturing device for a rubber gate valve. Background Art

[0002] The rubber gate valve mainly utilizes the overall rubber coating of the gate to produce deformation compensation to achieve a good sealing effect, overcoming the poor sealing, leakage or corrosion of general gate valves. In the rubber production process, a manufacturing device, that is, a mold, is usually used for rubber injection production.

[0003] According to the description of a rubber manufacturing device for a rubber gate valve disclosed on the patent website (authorization announcement number: CN 213704277U), "the utility model discloses a rubber manufacturing device for a rubber gate valve, which belongs to the technical field of rubber gate valve production, including a mold base, a bottom mold is installed on the top of the mold base, a top mold is installed on the top of the bottom mold, a plug hole is opened inside the mold base, and a control rod extending to the bottom of the mold base is installed at the bottom of the bottom mold. A limit plate corresponding to the position of the plug hole is fixedly connected to one side of the surface of the control rod, and the control rod is pulled downward until the bottom mold is completely attached to the inside of the mold base, and the control rod is rotated to adjust the direction of the limit plate so that the limit plate is not aligned with the plug hole. After the shaping is completed, the top mold is reset to complete the mold opening, the control rod is twisted, and the direction of the limit plate is adjusted until the limit plate is aligned with the plug hole. The control rod is released, and the bottom mold is automatically lifted up and separated from the mold base under the elastic force of spring A, which is convenient for material removal. Compared with traditional production molds, the convenience of material removal is improved, saving time and effort."

[0004] In view of the above description, the applicant believes that there are the following problems:

[0005] During use, the utility model can automatically lift up the bottom film under the action of elastic force through the provided spring A to facilitate material removal, and can limit the movement of the top film by using the limiting hole and the limiting rod to prevent it from deflecting. However, in actual use, since the injection molding of rubber requires waiting for the raw materials to cool before demolding, and the cooling time is generally very long, the manufacturing device does not have a structure for quickly cooling the mold, resulting in too slow cooling of the injection molding raw materials, affecting production efficiency. Therefore, it is necessary to improve a rubber manufacturing device for rubber gate valves to solve the above problems. Utility Model Content
