Abstract

PURPOSE: To manufacture a molding die at low price and thereby enable the die to be aplied to a small batch production by injecting a resin into a silicone rubber mold and curing the resin for the manufacture of illumination equipment. CONSTITUTION: When manufacturing illumination equipment, a small quantity of liquid silicone rubber, for preparing a mold, which contains a curing agent, is, first, charged into an outer frame 2, then a globe-shaped mold 1 for illumination equipment is insetted in a little time when the silicone rubber is slightly cured. After that a molding material 4 for an infection orifice of inverted triangular shape and a molding material 5 for a columnar air hole are placed on the globe-shaped moldy and then the liquid silicone rubber is injected into the die. After the curing of the injected silicone rubber, the outer frame 2 is removed from the silicone rubber mold 3, then the molding-material 4 for an injection orifice and the molding material 5 for a columnar air hole are taken out, and the globe-shaped die is also retrieved by cutting the rubber mold 3 with a razor blade. Further, the cutting slit of the rubber mold 3 is closed, and a phototransmissive resin is injected into the mold from the injection orifice 4-1, and at the same time, the internal air of the mold is discharged to an atmosphere from an air hole 5-1. Later, both injection orifice 4-1 and air hole 5-1 are tightly closed and finally, the globe for illumination equipment is taken out by curing the resin.

Description

DETAILED DESCRIPTION OF THE INVENTION Explanation of Terms (Terms in Section 1) i) A container is a food container, a flower pot, a vase, or a container for storing other than food. ii) The resin is a resin which mainly contains a curing agent for methacrylic resin or a curing agent and a curing accelerator, and which is cast and cured. The resin examples are shown below. The mixing ratio of the curing agent and the curing accelerator of methacrylic resin, the heating time, the heating temperature, the cooling temperature, etc. are one example, and the other mixing ratios, the heating time, the heating temperature, the cooling temperature, etc. Including. A) For the curing of methyl methacrylate (hereinafter referred to as MMA), benzoyl peroxide (hereinafter referred to as BPO) was added to BMA 0.5% based on the weight ratio of MMA, and stirring was started. The mixture was heated in a water bath to 80 ° C. A resin that is rapidly cooled to room temperature with cold water and heated to 80 ° C. and then rapidly cooled to room temperature to cast a slightly sticky liquid and cure at room temperature.
(The resin referred to in this section is also referred to as a syrup.) B) MMA 40 to 50% and polymer powder (30 to 80 mesh MMA granular polymer) 50 to 60% are sufficiently stirred at room temperature to swell and dissolve the polymer powder in MMA. Then, the resin injection port and the mold air hole are sealed with cellophane paper and put into an autoclave machine that can be pressurized with carbon dioxide gas, and can be heated. resin. C) A material obtained by adding the polymer powder or the like in the above-mentioned B to MMA, the name of which is called syrup.
0.2% to 0.5% of curing accelerator SY-A (manufactured by Mitsubishi Rayon Co., Ltd.) with respect to a weight ratio of trade name SY-430 (manufactured by Mitsubishi Rayon Co., Ltd.) which is an example.
A resin that cures at room temperature by adding 0.2 to 0.5% of a curing agent of a 55% solution of methyl ethyl kent peroxide and then thoroughly stirring and casting a slightly sticky liquid. D) A resin in which a methacrylic resin is cured by UV irradiation, or a material obtained by adding a curing agent and a curing accelerator is cast in a silicone rubber mold and cured by UV irradiation. The casting mold of this item does not include the wood type and clay type of the first claim, but only the silicone type. iii) Resin that is cured in a room by casting a material containing an unsaturated polyester curing agent and a curing accelerator. In the present invention, a resin containing a curing agent or a curing agent and a curing accelerator in a mold such as a silicone rubber mold, a wooden mold, or a clay mold or a resin obtained by stirring MMA and polymer powder is poured to manufacture the above product. The present invention relates to products manufactured by molding and curing. Although products using synthetic resins have been manufactured in the conventional market, pellets of methacrylic resin, ABS resin, and nylon resin used in these products are injection molding machines and blow molding machine molds. The molds used in injection molding machines and blow molding machines are put in the molds and are processed and processed to become expensive from several million yen to several million yen. The price has the drawback that it cannot be made cheap. The present invention has been made in order to eliminate such drawbacks, and FIG. 1 and FIG. 2 are examples of the resin injection mold required for making a lighting fixture globe.

(3) is a silicone rubber mold after the liquid silicone rubber for molding is cured, (4) is an injection port molding material for injecting resin when casting a lighting equipment globe, and (5) is injecting resin. At this time, it is an air hole molding material for discharging the air in the silicone rubber mold (3) to the outside of the mold. When making the luminaire (10) of FIGS. 3 and 4, initially, a small amount of liquid silicone rubber for molding which contains a curing agent necessary for curing is put in the outer frame (2). Put the lighting equipment glove type (1) in a slightly cured place. After that, an inlet molding material (4) having a shape obtained by cutting the apex of the inverted triangle and a cylindrical air hole molding material (5) are placed on the lighting equipment globe mold (the inlet molding material (4) and the air holes). The molding material (5) is made of silicone rubber or the like in advance.) Then, a casting liquid silicone rubber containing a curing agent is cast. After the curing time after casting, remove the outer frame (2) from the silicone rubber mold (3) and take out the injection port molding material (4) and the air hole molding material (5) in the silicone rubber mold (3). Cut the silicone rubber mold (3) with a razor blade (use a thin blade with a thin blade) to cut the lighting equipment glove mold (1) in a way that is easy to take out (when cutting, the silicone rubber mold (3))
