Description

Technical Field

[0001] The utility model relates to the technical field of mold processing, in particular to a combined upper mold. Background Art

[0002] Compression molding usually refers to the process of placing solid silicone raw materials with added vulcanizers in a high-temperature mold and applying pressure through a vulcanizing machine to solidify them. Compression molding is a common process for producing liquid silicone products.

[0003] In order to meet the needs of actual production, some products need to be composed of two semi-finished products. First, a semi-finished product is molded with a set of molds. After the semi-finished product is vulcanized, it is trimmed, ground, treated with chemicals, and brushed with adhesives. Then another semi-finished product molded by another set of molds is added, and then ground, treated with chemicals, and brushed with adhesives. Then the two blanks are heated and bonded, and then put into the mold and pressurized into one.

[0004] Therefore, multiple sets of molds must be used when processing two semi-finished products. The two sets of molds for processing the two semi-finished products are independent of each other, which increases the mold production cost. In addition, when the products are processed, the two semi-finished products need to be separated from the mold and then re-pressed, which increases the operational burden and affects the product processing efficiency. Utility Model Content

[0005] In view of the deficiencies in the prior art, the utility model provides a combined upper mold, which can have a common mold structure when processing products with different shapes, preventing the molds from being used independently and improving the versatility of the molds. After the bottom shape of the product is processed, there is no need to separate the product to meet other shapes. The upper plate that matches the middle plate is replaced with the top mold, and the continued molding of the product can be successfully completed. Through the second molding and pressing, the product shape can be directly processed, reducing the operating burden and improving the processing efficiency of the product.

[0006] In order to solve the above technical problems, the utility model adopts the following technical solutions:

When the bottom of the top mold cooperates to extend into the top of the side plate and the middle plate, the third molding cavity is connected to the second molding cavity.

[0009] Among them, a fourth molding cavity is penetrated from top to bottom on one side of the middle plate, and when the bottom of the top mold is extended into the top of the side plate and the middle plate, the second molding cavity, the third molding cavity and the fourth molding cavity are connected.

[0010] The bottom of the upper plate has a fifth molding cavity, and when the upper plate is matched with the middle plate, the first molding cavity and the fifth molding cavity are connected.
