Abstract

PURPOSE:To apply to a cast item a synthetic resin decorative body having a quite smooth finished surface, by using a receiving device, pouring a synthetic resin in a space in a cast item having a through-hole and a rib and hardening the resin. CONSTITUTION:The cast item of aluminum or the like about 10mm. in thickness is formed with the through-hole 1 at a suitable position, and the rib 2 extending circumferentially inward from the through-hole 1. The receiving device 3 of silicon or the like is abutted on the undersurface of the rib 2, and a synthetic resin such as an epoxy type resin is poured in the through-hole 1 followed by hardening. Then the receiving device 3 is removed, the cast item is upset, and the synthetic resin is poured in a recess defined by the circumferential edge of the through-hole 1, the rib 2 and said hardened synthetic resin followed by hardening so that the intended cast item that has a synthetic resin decorative body may be obtained.

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a method for applying a decorative body made of synthetic resin to a casting, and its purpose is to provide an extremely smooth finished surface on both the front and back surfaces in the voids of the casting. A decorative body made of synthetic resin is molded to give a cast product a beautiful appearance with multicolored light.

As a result of detailed studies to eliminate such defects, the inventors of the present invention established a through hole (1) at an appropriate position and formed a lip (2) on the inner periphery of the through hole. For cast products, a receiver is installed on the opposite side of the rib (2) in the through hole (1)
8) to inject and harden the synthetic resin into the through hole (see Figure 1), then remove the receiver (8) of the through hole (1) (see Figure 2), and Periphery of 1) and rib (2)
The desired purpose is achieved by injecting a synthetic resin into the recesses formed by the cured synthetic resin (4) and curing it.

0 approximately elliptical shaped through hole (1), and a lip (2) with a width of approximately 2gu* and a thickness of approximately 511M at the vertical center position of the through hole.
A synthetic resin mixed with an appropriate amount of a silicone hardener is poured along the lower surface of the rib until it reaches a position lower than the casting surface, and is heated at a temperature of approximately 60'C. Approximately 20
After holding for 2 hours and curing at 40'C for 2 hours, remove the silicone receiver and remove the tool (8), then turn the casting upside down to remove the periphery of the hole (1), the lip (2) and the hardened silicone receiver. The same synthetic resin as described above was injected into the recessed portion formed by the synthetic resin (4) and cured under the same conditions.

According to the method of the present invention, the free-flowing surfaces of both the front and back surfaces of the synthetic resin layer are thermally cured as they are, resulting in a highly aesthetically pleasing finished surface that gives an extremely smooth and wet appearance. The inner synthetic resin layer fits into the lip and can be attached very firmly.
