The invention discloses a molding combination structure of a plastic part and fabricated parts. The molding combination structure comprises the plastic part, first fabricated parts and second fabricated parts are arranged on the left side and the right side of the plastic part respectively, a containing groove is formed in each first fabricated part, the second fabricated parts are arranged in the containing grooves, grooves are formed in the upper ends of the first fabricated parts, the side walls of the grooves are slopes, a plurality of sharp corners protruding out of the bottoms of the grooves are arranged at the bottom of each groove, a filling groove is formed between every two adjacent sharp corners, the first fabricated parts and the second fabricated parts are coated with the plastic part, and the grooves of the first fabricated parts and the filling grooves in the bottoms of the grooves are filled with the plastic part. Sealing performance between the plastic part and the fabricated parts can be improved, and therefore the influence of the exterior on a part in the use process is reduced, the service life of part running is prolonged, and the stability of part running is improved.
Description
technical field [0001] The invention relates to a molding combination structure of a plastic part and a prefabricated part. Background technique [0002] Insert molding in the plastics industry is to put something into a mold and then injection mold it. The objects put into the mold are generally called prefabricated parts, which are generally used in industries such as automobiles, electronics, and medical treatment. During the part molding process, the plastic is injected onto the surface of the preform by heating the material tube, and then cooled to adhere to the surface of the preform. When the adhesion between the plastic and the prefabricated parts is not enough or the parts are soaked in water for a long time, electric leakage or short circuit will occur, resulting in failure of parts, failure of the whole machine to operate normally, and serious accidents. Contents of the invention [0003] In order to solve the above technical problems, the purpose of the prese...
