Description

Technical Field

[0001] The utility model relates to the technical field of rubber moulds, in particular to an improved mould for a silicone product resistant to high voltage electrical breakdown. Background Art

[0002] With the rapid development of material technology, silicone encapsulation is more common in the manufacturing industry. Silicone products are a layer of liquid silicone wrapped 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.

[0003] Existing silicone products are processed by molding technology, which requires operators to arrange materials accurately, otherwise the product is prone to wind, resulting in a decrease in high-voltage electrical breakdown performance or failure. The molding process has poor material bonding performance and is easy to break, which can easily cause a decrease in high-voltage electrical breakdown performance or failure. At the same time, due to the problem of burrs in the molding process, the mold line is rough and the alignment line is easy to tear, resulting in a decrease in high-voltage electrical breakdown performance or failure. During the production operation, the slider needs to be operated manually alone, which is inefficient and labor-intensive. Therefore, there is a need for an improved mold for silicone products that are resistant to high-voltage electrical breakdown. Utility Model Content
