Problems solved by technology

The traditional method is usually to test the welding line of the mold and fail to meet the quality requirements, and then adopt methods such as changing and adjusting process parameters, gate positions, modifying material thickness, changing materials, etc. This method increases the development cost and cycle of parts, and is not recommended

Embodiment Construction

[0031] The specific embodiments of the present invention will be described in detail below in conjunction with the accompanying drawings.

[0032] Such as Figures 1 to 3 As shown, the wheel decoration cover 1 includes a body 3, and some large holes 2 are arranged on the edge of the body 3, and it is characterized in that: the large hole 2 has a left edge 21, an inner edge 22, a right edge 23 and an outer edge 24. 3±0.1mm,.

[0033] The thickness of the body 3 is 2.5±0.1mm.

[0034] The thickness of body D at the left outer corner of the large hole is 2.5±0.1mm, and the thickness of body E at the right outer corner of the large hole is 2.5±0.1mm.

[0035] Such as Figure 6 As shown, the material thickness after optimization is 3 mm except for the flanging of the large hole 3, and the material thickness of the rest of the main body 3 is 2.5 mm, including the main body D at the left outer corner of the large hole and the main body E at the right outer corner of the large hole...

Abstract

A vehicle wheel decoration cover comprises a body, a plurality of large holes are formed in the edge of the body, each large hole is provided with a left edge, an inner edge, a right edge and an outer edge, and the left edge, the inner edge, the right edge and the right edge of each large hole are each 3+ / -0.1 mm thick. The thickness of the body is 2.5+ / -0.1 mm. Thus, the vehicle wheel decoration cover has the advantages that material thickness distribution is optimized, so that the confluence angle of fusant is large after the fusant flows through the square holes, no weld line is formed, appearance quality is guaranteed, and meanwhile mechanical strength is improved.

Description

technical field [0001] The invention relates to a decorative cover for automobile wheels. Background technique [0002] like figure 1 As shown, the wheel decoration cover 1 is assembled outside the wheel hub of the automobile and mainly plays a decorative role. Its plastic base material is usually PP+30% Talc. In order to add a metallic texture to it, it needs to be sprayed with silver powder varnish after injection molding. [0003] in such as image 3 As shown, the wheel decoration cover 1 includes a body 3 , and several large holes 2 are arranged on the edge of the body 3 , and the large holes 2 have a left edge 2 , an inner edge 22 , a right edge 23 and an outer edge 24 . Since the wheel trim cover 1 is in a regular shape, the usual pouring method is the center pouring of the rear single-point needle valve hot runner. like figure 2 As shown, pouring is poured from the glue feeding position B in the center of the wheel trim cover 1, and flows and spreads around alo...
