TECHNICAL FIELD

[0001] The utility model relates to the technical field of silicone rubber sealing piece processing, specifically relates to a silicone rubber sealing piece forming die. BACKGROUND

[0002] The silicone rubber sealing piece is a sealing element made of silicone rubber material, and has unique physical and chemical properties. The main chain of the silicone rubber is alternately composed of silicon and oxygen atoms, and the silicon atoms are usually connected with two organic groups. This structure endows the silicone rubber with excellent high and low temperature resistance, good elasticity, excellent insulation performance and chemical corrosion resistance. Therefore, the silicone rubber sealing piece is widely used in electronic, mechanical, aerospace, household appliances and other fields.

[0003] In the existing silicone rubber sealing piece production process, the silicone rubber sealing piece needs to be demolded. Since the surface of the silicone rubber sealing piece is relatively smooth, it may be adsorbed on the groove of the mold, which makes it difficult to demold. Moreover, the temperature of the just-formed silicone rubber sealing piece is still high, which is quite inconvenient for manual demolding. Therefore, we propose a silicone rubber sealing piece forming die to solve the above-mentioned problems. UTILITY MODEL CONTENTS
