The frame 91 is thick and the lattice portion 92 is thin.

一定となるように，成形する方法が採用されている。When the radiator grille 9 is formed according to the above-described shape, the thick frame 91 has a larger molding shrinkage than the thin grid portion 92. Therefore, as shown in FIG. 7, a wavy deformation 99 may occur in the thin grid portion 92. Therefore, as shown in FIGS. 5 and 6,
A method is employed in which the frame 91 is formed in a U-shaped cross section so that the thickness of each portion is constant.

When the frame 91 needs more rigidity, a method is employed in which the frame 91 is formed separately from the lattice portion 92 and then the two are assembled.

That is, when the frame 91 and the lattice portion 92 are integrally formed, the frame 91 has a U-shaped cross section, and a rib 93 is provided partially. Therefore, the mold becomes complicated and its design is difficult. The wavy deformation 99 may occur due to the difference in the molding shrinkage between the frame 91 and the lattice portion 92.

The present invention has been made in view of such conventional problems, and aims to provide a synthetic resin frame having excellent mechanical strength such as rigidity without deformation due to a difference in molding shrinkage. It is.

A low molding shrinkage resin material such as polybutylene terephthalate (PBT) resin is used. Also, the low shrinkage material of the core layer has a molding shrinkage that is about 10 to 50% lower than that of the skin layer material. If the difference in molding shrinkage is less than 10%, the difference in molding shrinkage due to the wall thickness cannot be eliminated, while if it exceeds 50%, the molding shrinkage in the frame portion decreases.
The low shrinkage material may contain a foaming agent and an inorganic filler such as glass fiber and talc.

At least the frame portion has a sandwich structure including a skin layer and a core layer. The core layer is made of a low-shrink material having a lower molding shrinkage than the skin layer. Therefore, in the present invention, the molding shrinkage ratios of the frame portion and the lattice-like body are equal.

よる変形を生じない。The reason is considered to be as follows. That is, since the frame portion is thicker than the lattice portion, the molding shrinkage is generally large. However, in the present invention, the frame portion has a sandwich structure using a low shrinkage material. Therefore, the molding shrinkage ratios of the frame portion and the lattice portion are substantially equal. As a result, there is no difference in molding shrinkage between the frame portion and the lattice, and no deformation due to the difference in molding shrinkage occurs.

Since glass fiber (GF), talc, and the like are added, the mechanical strength, particularly the rigidity of the frame portion, is further improved. On the other hand, when a foaming agent is added to the low-shrinkage material, the weight of the frame portion can be reduced. In addition, the occurrence of sink marks can be prevented. As described above, according to the present invention, it is possible to provide a synthetic resin frame which does not cause deformation due to a difference in molding shrinkage, is easy in mold design, and has excellent mechanical strength such as rigidity.

Next, in molding the radiator grill 1, an ABS resin for forming the skin layer 111 is first injected into a mold (not shown). Next, a low-shrinkage material for forming the core layer 112 is injected into the skin material. As a result, as shown in FIGS. 1 and 2, the upper frame 11A and the lower frame 11B have a sandwich frame 11a.
And a radiator grill 1 having a grid-like body 12 are obtained.
