Description

Technical Field

[0001] The utility model relates to the technical field of mold processing, in particular to a waterproof cover processing 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 waterproof covers need to be composed of two semi-finished products. First, a semi-finished product is molded with a set of molds, and then the semi-finished product is trimmed, ground, treated with chemicals, and brushed with adhesives after vulcanization. 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 to process two semi-finished products. The two sets of molds for processing the two semi-finished products are independent of each other, and there is no common structure between the multiple sets of molds. The molds have poor versatility, which leads to an increase in the mold production cost. Utility Model Content

Figure 3 , 10As shown in 11, when the upper plate 3 is separated, the hardware can be inserted into the cavity corresponding to the partition plate 301. Since the top surface of the boss 101 is provided with a positioning column 103, the hardware is provided with a positioning hole matching the positioning column 103. The hardware is smoothly installed through the guiding effect of the positioning column 103 and the positioning hole, which improves the installation accuracy of the hardware and improves the structural performance of the product.
