Description

Technical Field

[0001] The utility model relates to the technical field of rubber moulds, in particular to a liquid silicone aluminium part double-sided glue-coated integrated mould. Background Art

[0002] With the rapid development of material technology, silicone encapsulation is more common in the manufacturing industry. Silicone encapsulation is used to wrap a layer of liquid silicone on some metals, rubbers, plastics and other materials. By using the material properties of silicone, it has the advantages of good hand feel, aging resistance, good release, and anti-slip. Silicone encapsulation is the best packaging material for products.

[0003] However, during the product encapsulation process, the existing double-sided encapsulation products will have a long cooling time for the silicone molded product due to poor heat dissipation, which will increase the time required for the overall molding of a product, resulting in low work efficiency. In addition, the need to turn over the encapsulation will cause many special situations during the molding process, such as debonding, damage to the secondary encapsulation of aluminum parts, etc. During the silicone heating molding process, due to poor insulation effect, residual glue will condense in the injection pipe, making it difficult to clean. Therefore, it is necessary to provide a liquid silicone aluminum double-sided encapsulation integrated molding mold. Utility Model Content
