Embodiment 1

[0043] A process for producing resin shaping tooling for engine decorative cover includes the following steps:

[0044] The first step is to weigh the raw materials according to the following parts by weight: 80-100 parts of epoxy resin, 4-5 parts of modified aluminum nitride, 3.2-4 parts of calcium sulfate whiskers, 10-12 parts of curing agent, solvent 72-90 copies;

[0045] The second step is to place the epoxy resin in an oven at 80°C to dry for 60-70 minutes to remove bubbles in the epoxy resin, reduce its viscosity, and seal it for later use;

[0046] The third step is to place the solvent in a 60°C water bath, magnetically stir for 40-50 minutes, then add modified aluminum nitride and calcium sulfate whiskers, continue to stir in a constant temperature water bath for 70-80 minutes to obtain a mixed solution;

[0047] The fourth step, add the epoxy resin dried in the second step to the mixed solution, place it in a 60℃ water bath and stir it magnetically for 55-65min, add the cur...

Abstract

The invention discloses a process for producing a resin shaping tool for an engine decorative cover, and the process comprises the following steps: (1) preparing materials; (2) drying epoxy resin; (3)preparing a mixed solution; (4) preparing resin liquid; (5) placing a produced engine decorative cover product into a mold cavity for natural cooling, pouring the resin liquid on the installation surface of the product, uniformly stirring to enable the resin liquid to fill gaps on the installation surface of the engine decorative cover product, and then naturally cooling and forming; and (6) drying. The shaping tool is made of a resin material, the epoxy resin is taken as a resin matrix, and modified aluminum nitride and calcium sulfate whiskers are added; compared with the traditional iron shaping tool, the shaping tool has the following advantages: the manufacturing method is simple, the time consumption is short, the cost is low, and the working efficiency can be greatly improved; Light weight, easy to move; and resin is softer than metal and has more advantages in use safety. The resin shaping tool has good high temperature resistance and fast heat dissipation.

Description

Technical field [0001] The invention belongs to the technical field of resin materials, and specifically relates to a process for producing resin shaping tooling for engine decorative covers. Background technique [0002] The engine decorative cover shaping tooling is used to cool and shape the newly produced engine decorative cover. The existing shaping tooling is made of iron materials, which has long service life, high hardness, smooth surface, precise size and good damage resistance. The mold surface is not easy to wear and other advantages, but its cost is high and the heat dissipation is slow. Therefore, shaped tooling made of resin materials came into being. [0003] Chinese Patent 201310594299.3 discloses a resin mold and molding process, including the following components: epoxy resin, brown corundum, epoxy resin curing agent and talc. The molding process includes the following steps: male model making and resin liquid preparation: The preparation method of the resin sol...
