A die-cutting mold for automotive interior parts

Abstract

The invention discloses an automobile interior trim part punching forming die. The automobile interior trim part punching forming die comprises a base with the top provided with a die base. A die cavity is formed in the die base. A heating cavity surrounds the outer side of the die cavity. Supporting blocks are arranged on the two sides of the die base. Punching devices are arranged on the inner sides of the supporting blocks. A top plate is arranged on the top of the die base. A lifting plate is arranged at the bottom of the top plate. Fixing rods are evenly arranged between the lifting plateand the top plate. A heating plate is arranged at the bottoms of the fixing rods. The interiors of the heating cavity and the heating plate are filled with heating coils. Through the arrangement of the heating cavity and the heating plate, formed raw materials obtained after hot melting are extruded to enter the die cavity through an injection molding screw, then, hydraulic lifting rods work anddrive the top plate to descend, the heating plate is closely attached to the raw materials in the die cavity, and the heating coils in the heating plate and the heating cavity work and heat the raw materials in the die from the top and the bottom; and through all-direction thermoplastic forming work, the raw materials are rapidly formed, and the work efficiency is improved.

Description

technical field [0001] The invention relates to the field of moulds, in particular to a die for punching and forming automotive interior parts. Background technique [0002] With the increasing calls for environmental protection and energy saving in the international environment, and in order to cope with the urgent global warming and energy crisis, automobile lightweight technology has become one of the reliable ways to effectively alleviate the energy and climate crisis in the short term. The so-called automobile lightweight technology refers to the energy-saving design and improvement of each assembly and parts of the automobile under the premise of ensuring the basic performance of the automobile, so as to reduce the quality of the overall equipment of the automobile, thereby improving the power performance of the automobile and reducing fuel consumption. and exhaust pollution. Existing automotive interior and exterior parts products: such as wheel fenders, engine botto...

AI Technical Summary

Problems solved by technology

[0003] The object of the present invention is to provide a punching mold for automotive interior parts, through which a heating chamber and a heating plate are provided, the hot-melted molding raw material is extruded into the mold cavity through the injection screw, and then the hydraulic lifting rod works to drive the top plate Lower, put the heating plate close to the raw material in the mold cavity, the heating plate and the heating coil in the heating cavity work, respectively heat the raw material in the mold from the top and bottom, and make the raw material rapid prototyping through all-round thermoplastic molding , improve work efficiency, in order to solve the problem that the outer side of the mold is used to heat the mold to shape the jewelry, the production efficiency is low, the production speed is slow, the production cycle is long, and the labor cost is high.
