Embodiment Construction

[0024] Such as figure 1 As shown, a manufacturing process of a simple inspection tool for the detection of wheel housing spacers, it includes the following steps:

[0025] (1) Obtain the 3D data of the simple inspection tool according to the outline size of the wheel house spacer.

[0026] (2) Process the polyurethane foam block into the main body of the inspection fixture with a CNC machine tool, and require a negative 0.7mm processing of the surface.

[0027] (3) Blow off the dust and impurities on the surface of the main body of the processed inspection tool.

[0028] (4) Spray the prepared gel coat on the main surface of the inspection fixture. It needs to be sprayed in two layers. The first layer of gel coat is sprayed a little thinner and sprayed 20mm. After the first layer of gel coat is sprayed, wait for 20 minutes before continuing to spray the second layer. For gel coat, the second layer of gel coat should be sprayed thicker, spraying 50mm, and the two layers of ge...

Abstract

The invention relates to a manufacturing process of a simple testing fixture. A polyurethane foaming block is used as a material. The design is reasonable and ingenious. The polyurethane foaming blockis used for replacing previous processing testing fixtures made of aluminum and wood materials; the processing becomes convenient and rapid; and the cost is lowered. With the manufacturing process provided by the invention, the testing fixture processed by the polyurethane foaming block has the hardened surface and high smoothness; and the fixture usage demand is satisfied.

Description

technical field [0001] The invention relates to the technical field of mold detection, in particular to a simple mold manufacturing process. Background technique [0002] Inspection tools are simple tools used by industrial production enterprises to control various dimensions of products (such as aperture, space dimensions, etc.), improve production efficiency and control quality, and are suitable for mass-produced products, such as auto parts, to replace professional measuring tools , such as smooth plug gauges, threaded plug gauges, outer diameter snap gauges, etc. At present, in the field of automotive interior processing, inspection tools for automotive interior and exterior front wall, spacers such as carpets, and wheel cover spacers are generally made of aluminum or wood substitutes, which is inconvenient and expensive to process. Contents of the invention [0003] In order to solve the above problems, the present invention provides a simple mold manufacturing proce...
