Embodiment Construction

[0023] The technical solutions in the embodiments of the present invention will be described clearly and completely below. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative work shall fall within the protection scope of the present invention.

[0024] In the embodiment of the present invention, a pressing mold manufacturing process, the specific steps are:

[0025] S1. Preparation before making: apply mold release wax on the surface of the existing wooden workpiece model, and then spray gel coat on the wooden workpiece model;

[0026] S2, upper mold production: paste liquid FRP raw materials on the surface of one side of the wooden workpiece model, and fix the rectangular angle steel frame around the wooden workpiece model. The FRP raw materials are in the rectangular a...

Abstract

The invention discloses a production technology of a pressing die. The production technology comprises the following steps: preparing before production, producing an upper die, carrying out fine trimming on the upper die, producing a lower die, debugging the dies and carrying out trial production of a product. After the upper die is produced, the lower die is produced through a local gluing, de-molding and waxing method; compared with an existing production technology of the pressing die, the technology does not need to adopt a manner of washing glue on the surface and scraping red oil after cutting, polishing and repairing are carried out to produce the die. Therefore, in a subsequent die production process, the die does not need to be degummed. Visibly, the technology provided by the invention is improved so that the labor cost and the production period can be reduced. In actual production, the production technology of the pressing die, provided by the invention, is adopted; after the production technology is implemented, the production time of a pair of the dies can be reduced by 10 to 20 working days, and the die production precision and accuracy also can be improved to be higher.

Description

Technical field [0001] The invention relates to the field of industrial production, in particular to a pressing mold manufacturing process. Background technique [0002] Passenger car travel is one of the common travel modes for people. In order to improve people's travel experience, vehicle manufacturers will not only optimize the performance of passenger cars, but also decorate the interior to a certain degree to achieve a certain aesthetic effect. [0003] In order to prevent members of the car from being accidentally bumped by the trim, the car interior parts are usually passivated plastic parts. In order to reduce production costs, large-scale production of plastic parts often uses compression molds for compression molding. When industrial production is carried out by means of compression moulding, the most important thing is to make moulds in accordance with the design drawings. [0004] However, the existing pressing mold manufacturing process has the disadvantages of comple...
