In-mould assembling and welding structure

Abstract

The invention discloses an in-mould assembling and welding structure. The in-mould assembly and welding structure comprises a front mould core, a rear mould core, a pushing plate and a rear mould insert which are movably arranged on the upper surface of the rear mould core, an upper cover mould core which is arranged on the pushing plate for injection-molding an upper cover of a gas-liquid flow monitor and a main body mould core used for injection-molding a main body of the gas-liquid flow monitor; the rear mould insert is equipped with a lower forming cavity used for injection-molding a blade of the gas-liquid flow monitor; a lower assembly cavity is formed in the rear mould core; the lower assembly cavity is positioned at one side of the pushing plate and the rear mould insert; the front mould core is provided with a main body mould cavity used for injection-molding the main body of the gas-liquid flow monitor, an upper cover mould cavity used for injection-molding the upper cover of the gas-liquid flow monitor, an upper forming cavity used for injection-molding the blade of the gas-liquid flow monitor, and an upper assembly cavity used for assembling; the main body mould cavity, the upper cover mould cavity, the upper forming cavity and the upper assembly cavity correspond to the main body mould core, the upper cover mould core, the lower forming cavity and the lower assembly cavity respectively; and ejector pins are arranged underneath the rear mould core.

Description

technical field [0001] The invention relates to the technical field of injection molds, in particular to an in-mold assembly and welding structure. Background technique [0002] Under normal circumstances, the injection molding industry will make a single set of molds for a single product, produce the product, then assemble the product, and then weld the product together with ultrasonic technology; such as the gas-liquid flow monitor designed and produced by our company, the The product consists of three parts, so the traditional design will design three molds, and the parts will be produced separately. After the parts are produced, the three parts will be assembled into the whole gas-liquid flow monitor. The disadvantage of this design is: it needs to be done 3 sets of molds to produce products; post-processing assembly and ultrasonic welding are also required. This design results in a long process chain for production and high production costs. Contents of the invention...
