A kind of manufacturing method of plastic forming mold

Abstract

The invention discloses a manufacturing method of a plastic forming mold, which is characterized in that it comprises the following steps: (1) molding the mold according to the shape of the product; (2) pre-processing the The metal part is placed on the molding module, and the metal base frame is fixed on the metal part; (3) Evenly coat a layer of release wax on the surface of the modeling module, and after the resin glue and the reinforcing powder are mixed evenly, Coating on the surface of the modeling module, curing for 3 hours to make the green body, and then sticking the glass fiber cloth layer on the inside of the green body with resin glue; (4) Inserting steel wires in the base mold frame to form a three-dimensional network structure, Then pour concrete into the void in the mold frame, and then form it after curing. The manufacturing method of the plastic forming mold involved in the present invention is a manufacturing method of the molding mold which is completed synchronously by molding, edge trimming, hole opening and the like, and the mold making period is short, the cost is low, the performance and dimensional stability are good, and the production efficiency is high.

Description

technical field [0001] The invention relates to the field of polymer materials, in particular to a method for manufacturing a plastic molding die. Background technique [0002] At present, the commonly used molds for molding automotive interior parts are all-metal molds, plastic (resin) molds, etc. The metal mold has stable performance and high strength, and can realize the functions of forming, trimming and opening at the same time, but its production life is long and the cost is high; automotive products change quickly on the basis of basic models, especially the interior parts almost every two years Carrying out a modification, in the process of producing large-scale interior parts, due to the many states of automobile interior parts and the large amount of molds required, the cost of making metal molds is increased and the efficiency is low; the plastic resin mold made of glass fiber reinforced plastics takes a long time to cure , The performance and dimensional stabili...

Problems solved by technology

The metal mold has stable performance and high strength, and can realize the functions of forming, trimming and opening at the same time, but its production life is long and the cost is high; automotive products change quickly on the basis of basic models, especially the interior parts almost every two years Carrying out a modification, in the process of producing large-scale interior parts, due to the many states of automobile interior parts and the large amount of molds required, the cost of making metal molds is increased and the efficiency is low; the plastic resin mold made of glass fiber reinforced plastics takes a long time to cure , the performance and dimensional stability are not good, the strength is not enough, and the functions of forming, edge trimming and hole opening cannot be realized at the same time. Subsequent processing procedures such as edge trimming and hole opening are required, and the process is complicated and the production efficiency is low.
