Abstract

PURPOSE:To easily obtain a molding for vehicle excellent in dimensional stability by using a small number of parts, by a method wherein a metallic molded body provided with a through hole at an embedded part is placed in a mold for injection molding so that an exposed part makes contact with a mold surface, and then a foamable resin is injection molded. CONSTITUTION:The metallic molded body 6 provided with the exposed part 6a and the embedded part 6b and provided with the through hole 6c at the embedded part 6c is placed in a cavity mold 7 for injection molding so that the exposed part 6a makes close contact with a projected part 7a provided on the mold surface, a core mold 8 is lowered, the mold is clamped, a pressing pin 9 is pressed against the back side of the exposed part 6a of the molded body 6 on the side opposite to the projected part 7a, and the exposed part 6a is brought into close contact with the projected part 7a. Then, a foamable resin 13 is injection molded into a cavity 12 through a sprue 10 and a gate 11 to obtain the molded article 1 for vehicle wherein the exposed part 6a is exposed as a metallic part 3 and both sides of the embedded part 6b are covered by clamping with resin part 2.

Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a method for manufacturing a molding indium for a vehicle, and more particularly to a method for manufacturing a molding for a vehicle having a metal and synthetic resin content of 15%.

This is a JAN-shaped molding ink for vehicles, which has gold on the outer surface and a synthetic resin part. Fig. 1 are the iE and ir?i diagrams of Decter Molding 7-1 of this type of vehicle.

Inno 1 - The conventional manufacturing and crushing method is to simultaneously extrude the resin part 2 with the core (4) embedded, cut it to a predetermined size and treat the ends, and then form the metal part 6. The conventional manufacturing method is to assemble the metal molding into the metal molding, or to co-extrude the metal-colored 21+ and process the ends to manufacture the molding 1.

It is a presser bottle.

The manufacturing method for the molding plate 1 is as follows: First, a metal plate is press-molded to form a metal molding hole 6 that collapses the exposed portion 6a, the mounting portion 6b, and the through hole 6c. , the exposed part 6a or the metal part 6 from the molding 1 is exposed at 5, so you can paint the other parts in the same way. The hole 6c is shown in Figures 4 and 8.
Other arrangements than those shown in Figure 1 may be used, and the appropriate sound may be selected depending on the overall size, intensity, etc.

The shape, number, etc. of the through holes 6c are also the same.

Next, how do I install the metal molding plate in the injection mold and perform injection molding? First, open the mold as shown in No. 9, and place the metal molding plate in the cavity mold Z.
At this time, the exposed part 6a of the molding is brought into contact with the protruding part 7a formed on the mold surface of the cavity mold 7.Then, the core mold 8 is removed. \”L
Clamp the mold with

Next, when the foamed E1 resin 16 is injected into the Lf gap space 12 through the stripe 10 and gate 11, the resin 16 leaves the exposed part 6a of the metal mold ink 6 and covers both sides of the buried part 6b. The resin part 2 is formed by using the buried part 6b as a core material and covering it in a filling state.This injection molding d1 reaction injection molding (R

Explanation (-17) According to the present invention, a metal molding having an exposed portion, a buried portion, and a through hole formed in the buried portion is installed in a mold, and is then molded with foamed resin. Since it is configured to be injection molded, the following effects can be obtained.

(One metal part and the entire fat part can be molded at the same time, eliminating the assembly process and reducing the number of culms and parts.

Q) The buried part acts as a core, provides rigidity, is prevented from shrinking, and has excellent dimensional stability.

The dome that forms the ¥ part has a decorative and protective effect, and it is anchored in a Zantoisoji shape, so it does not peel off or
It can be prevented from falling off.

(5) There is no joint between the metal part and the resin part, so the appearance is unclear.
