V type belt inducing hot pressure forming module

Abstract

The invention provides a V-shaped belt induction thermo-compression type mold, which comprises a right end cover 1, a right sealing head 2, a nut 3, a housing 4, an external induction coil 5, an upper heating plate 6, a combination die cavity 7, an internal induction coil 8, a screw rod 9, a left sealing head 10, a left end cover 11, a cover plate 12, an injection joint 13, an exhaust joint 14, acoil fixing plate 15 and so on; wherein the internal induction coil 8 is arranged in the combination die cavity 7; the combination die cavity 7 is positioned by inner holes in the left end cover 11 and the right end cover 1 and an ideal shape can be realized by the pyramidal faces of the left sealing head 10 and the right sealing head 2. The external induction coil 5 is arranged between the heating plate 6 and the housing 4. The device is tensioned by four screw rods 9 through the left and right end covers. The upper heating plate 6 and the combination die cavity 7 are matched by a clearance,and the installation positions of the upper heating plate 6 and the combination die cavity 7 in the device are guaranteed by taper holes of the injecting joint 13 and the exhaust joint 14. The invention is convenient for assembling and disassembling and can adapt to the thermo-compression forming of V-shaped belt products of various specifications; as the internal and external induction thermo-compression is adopted during the induction heating process, each part of the product can be thermo-compressed uniformly and the heat loss is less, thus leading the dimensional accuracy of the V-shaped belt to be comparatively higher, having good flexibility, wear resistance, tensile strength and flexing resistance, and improving the overall properties of the V-shaped belt.

Description

technical field [0001] The invention relates to the technical field of precision molding processing widely used in engineering plastic products, and is mainly used in the precision molding processing mold of V-shaped belts in the rubber industry. Background technique [0002] At present, new engineering composite products are widely used, such as some high-performance seals, rubber bearings, highly elastic couplings, V-shaped conveyor belts, etc. V-belts can be seen everywhere in various transmission fields. At present, most of its molding process adopts vulcanization molding. Compressed air and steam are used as the pressurized heating medium, and the V-belt mold is put into the vulcanization tank for heating; the second method is to heat the product by steam entering the annular heating cavity of the mold core, and steam hot-pressed vulcanization molding; The third method is resistance conduction hot pressing vulcanization molding method. [0003] These three methods hav...

Problems solved by technology

[0003] These three methods have the following disadvantages: 1. The hot pressing of each part of the molded rubber is uneven, which is greatly affected by the shape of the mold, making the product dimensional accuracy not high and not easy to quality control; 2. The hot pressing vulcanization time is long, and More heat loss, low production efficiency; 3. The control is difficult, which is not conducive to safe production
