Description

Technical Field

[0001] The utility model relates to the field of plastic inflatable mold processing, in particular to a plastic inflatable mold high-frequency welding device. Background Art

[0002] A plastic inflatable mold is a mold used for processing plastic products. It is made of metal materials, usually steel or aluminum alloy, with a complex inner cavity and shape. It is used to inject molten plastic into it and form the required plastic products through cooling and solidification processes. High frequency is a high-frequency electromagnetic field wave that can cause load ions to react. It has been widely used in industrial production and daily life, especially in the plastic processing industry.

[0003] The high-frequency welding equipment for plastic inflatable molds is a special equipment used for processing plastic products. It uses the heat energy generated by the high-frequency electric field to heat the contact surface of the plastic products to a molten state and weld them together by applying pressure. The high-frequency welding equipment usually does not need to add other adhesives or fillers during the welding process. It can directly weld plastic parts together, avoiding the additional costs and complexity that may be caused by using other materials.

[0004] However, during the operation of the high-frequency welding equipment for plastic inflatable molds, when the temperature of the hanging template exceeds a certain value, it is necessary to shut down the machine or dissipate heat manually. Otherwise, the temperature exceeds the melting point of the PET material and the mold will stick, making demolding difficult and seriously affecting production efficiency. Therefore, a high-frequency welding equipment for plastic inflatable molds is proposed to solve the above problems. Utility Model Content

[0033] Specifically, when the temperature of the template 4 is too high, the cooling water in the water tank 8 can be extracted by the air pump 2 7 and injected into the cooling box 5 to cool the template 4. When the temperature is not high, the cooling water in the cooling box 5 can be extracted by the air pump 1 6 and discharged back into the water tank 8. Inside the water tank 8, the motor 14 drives the worm 13 to rotate.
