Abstract

PROBLEM TO BE SOLVED: To form a plastic molding of a multilayer structure in a varying type of plastic material or a plastic material of different color in such a manner that the molding is water proof and air tight and firmly junctioned and also an elastic product is securely fitted. SOLUTION: The first layer part of a multilayer form is molded of a single plastic material as a base part 2a, and this base part 2a and a molded part consisting of a plastic material of different type or color from the base part 2a are combined together into a molded part as a second layer part 3a. Further, a molding die consisting of part of a mold face formed of the wall face of the second layer part 3a, and a plastic material which can be junctioned to the base part 2a is poured into the molding die to obtain a third layer part 4a in such a state that it is connected to the base part 2a. Thus the second layer part 3a which becomes an intermediate layer part is fitted into the base part 2a and the third layer part 4a as a multilayer form.

2. Description of the Related Art As a conventional molding method in which different kinds of materials or different colors are combined, a method of inserting a primary molded product and then performing a secondary molding after the primary molding, or a method of individually molding and providing a locking portion is provided. A method of fitting and combining and a method of joining with an adhesive are known. In the insert molding method, when molding rubber or the like by secondary molding, the secondary molding resin adheres to the mold. Further, in order to prevent this, the mold needs a coating treatment. When the secondary molded product does not have adhesiveness (silicon), a pretreatment such as a primer treatment for bonding the primary molded product is required. If liquid silicone, thermoplastic elastomer, or other high-fluidity elastic material is used in the secondary molding, it is necessary to minimize the variation in dimensions such as the mold combination surface, but the primary molded product is inserted. Therefore, dimensional variation occurs, and burrs occur on the combined surface of the housing and the mold. There is a problem. In addition, the method of providing a locking portion and fitting them together causes a problem that the time and cost required for the process of the combination increase. Furthermore, waterproofness and airtightness are not perfect in the method of combining at the locking portion or joining with an adhesive. It is necessary to prevent the locking part from coming off, but in the case of an elastic body, it becomes incomplete. In the case of an adhesive, it takes a lot of man-hours and it is difficult to apply the adhesive uniformly. There is a problem.

In the present invention, after molding the base portion, a separately molded component is used as a molding portion for the intermediate second layer, which is arranged in combination with the base portion, and then the second layer is formed. Since a mold with part of the wall surface of the molded part of is formed as a mold surface, the third layer of plastic material is poured and molded,
When the intermediate molded product is rubber, a coating process for preventing adhesion to the mold is unnecessary. Even if the second-layer molded product has no adhesive strength such as silicon, it is pre-treated for adhesion such as primer treatment to the base because it is stacked and locked by the base and the third layer. Is unnecessary. Further, since the base part and the second layer part are simply placed on the molded product in combination, burrs do not occur. Further, it is not necessary to lock the second layer portion and the base portion only by arranging them, and the intermediate molded product is locked by molding the third layer, so that the arrangement work is easy. Although the present invention has been described as having a three-layer structure, a multi-layer structure can be obtained by repeating this structure.

BEST MODE FOR CARRYING OUT THE INVENTION The base part of the present invention and a molded part for an intermediate second layer made of a different or different plastic material are molded independently to combine the base part and the two-layer part. Depending on the shape, the combination may be such that the two-layer component is placed on the base, or the base portion is placed on the two-layer component. The base part or the second-layer molded part may be a ready-made product. It is desirable that the base portion and the second layer portion are provided with unevenness so as to be fitted with each other to strengthen the locking. As the plastic material, thermoplastic resin (for example, known resin such as 6 nylon resin, 6-6 nylon resin, polybutylene terephthalate resin, polyphenylene sulfide resin, liquid crystal polymer), thermosetting resin, silicone, rubber, etc. Can be used, and can be applied to hollow products of different or different colors. In order to firmly fix it, a cavity that penetrates the base portion and the two-layer portion is provided so that the molded plastic material of the third layer wraps around.
