example 1

[0043] 1. Spray a special release agent on the surface of the product cavity of the first upper mold 1 and the second upper mold 2, so that the surface of the product cavity will not stick to the silicone raw material.

[0044] 2. Put the whole mold on a common hot press molding machine, and preheat the mold.

[0045] 3. The mold is opened, the lower mold 4 and the first upper mold 1 are opened, the first color silicone material of the first color product is put into the cavity of the lower mold 4, the molds are closed and the product is hot pressed. The vulcanization time of the first color product is 30s~400s, the molding temperature is 60~180°, and the molding pressure is 50~200Ton. When the raw material of silica gel of the first color product is vulcanized in one color, the raw material is not fully mature, and the degree of cure accounts for 20% to 40% of the complete degree of cure.

[0046] 4. After thermoforming, the first color product does not need to be taken out fr...

example 2

[0052] Such as Figure 4 and Figure 5 As shown, the difference from Example 1 is that while the two-color product 12 is thermocompressed in step 6, the third-color silica gel raw material can be put into the third color between the third upper mold 3 and the second upper mold. In the product cavity 7, the third color product 10 is hot-pressed at the same time;

[0053] When the mold is opened, the two-color product 12 stays in the mold cavity of the lower mold 4, and the third one-color product 10 stays in the mold cavity of the third upper mold 3;

[0054] After the mold is opened, the second upper mold 2 is slid away by the machine, the third upper mold 3 and the lower mold 4 are closed, and the third one-color product 10 and the second-color product 12 are hot-pressed to form a three-color product.

Abstract

A manufacturing method and manufacturing equipment of a multicolor solid silicone product are used for conducting hot press molding on solid silicone. The manufacturing equipment comprises a lower mold, and further comprises a first upper mold and a second upper mold. The first upper mold is located on the lower mold, and the second upper mold is located on the first upper mold. The first upper mold and the lower mold are compounded to form a first one-color product mold cavity used for hot press molding of a first one-color product. The first upper mold is arranged to be capable of sliding out of the position between the second upper mold and the lower mold, after the first upper mold slides out, the second upper mold and the lower mold can be compounded to form a two-color product mold cavity larger than the first one-color mold cavity, and therefore silicone raw materials can be added on the basis of the first one-color product to form a two-color product in a hot press molding mode without taking the first one-color product out of the lower mold. According to the manufacturing method and manufacturing equipment, cost is low, the equipment structure is simple, and manufacturing efficiency and the product yield are high.

Description

technical field [0001] The invention relates to a manufacturing method and manufacturing equipment of a multi-color solid silica gel product. Background technique [0002] Silicone products are high temperature resistant, easy to clean, long service life, soft and comfortable, and radiation resistant, and are widely used in various industries. [0003] Most of the existing multi-color silicone products such as three-color silicone products are made of liquid silicone, but the cost of making a two-color liquid silicone machine is high, and the mold structure is complicated and the cost is high. Due to the good fluidity of the liquid silicone raw material, the product still has bad phenomena such as serious glue overflow, the product yield rate is low, and the production capacity is low. [0004] Multi-color products are formed by hot-pressing solid silica gel. Taking three-color products as an example, one way is to put rubber materials of different colors into the mold cavi...
