Embodiment Construction

[0019] The present invention will be specifically introduced below in conjunction with the accompanying drawings and specific embodiments.

[0020] A plastic overmolding mold is composed of a base 2, an insert 13, a slider 6 and a movable mold 11.

[0021] The block 13 with the slot 12 is accommodated in the base 2 , and the top edge of the slot 12 is flush with the top edge of the base 2 .

[0022] A pair of sliders 6 are set on the top of the base 2, and are respectively placed on both sides of the socket 12, sliding along the top of the base 2, the bottom of which is connected with the rotating tooth 3 in the base 2, and passed by the screw rod 4 The rotating gears 3 are respectively driven, and the threads on the screw mandrel 4 are mirror-image symmetric.

[0023] The movable mold 11 inside accommodates a plurality of stacked moving blocks 7 to cover the top of the slider 6 , and forms a mold cavity 5 with the slider 6 and the slot 12 .

[0024] The pedestal 2 at the bo...

Abstract

The invention discloses a plastic coating mold. The plastic coating mold comprises a base provided with an caulking groove, wherein a pair of sliding blocks are arranged at the top of the base and areseparately arranged at the two sides of the caulking groove; a movable mold covers the top of the sliding blocks, and the movable mold, the sliding blocks and the embedded groove form a mold cavity;the sliding blocks are correspondingly driven by a screw rod in the base through rotating teeth; and an injection hole is connected to the mold cavity through the movable mold. An insert is fixed by the caulking groove, the size of the mold cavity is adjusted by the sliding blocks, and an outer space of a first firmware, namely, the size of an outer plastic coating is cooperatively adjusted by thesliding blocks and a moving block. Condensation is accelerated through a condenser tube. Various inserts are matched through the replaceable moving block and an embedded block. The injection hole isconnected with a plurality of plastic injection liquids to form a multi-layer and multi-material injection molded part through a directional valve. At the same time, demoulding and taking out parts are facilitated through opening and closing of the sliding blocks and the movable mold. The plastic coating mold is simple in structure, convenient to use, rich in functions and diversified in finishedproducts of injection molded parts, and has strong practicability and wide applicability.

Description

technical field [0001] The invention relates to a mold, in particular to a rubber overmolding mold. Background technique [0002] Injection molds are common tools for producing plastic products. [0003] After pre-installing metal parts or other inserts in the mold, and then injecting, it is insert injection molding. [0004] However, in actual production, it is often necessary to inject a layer of rubber coating on the outer layer of the injection molded part. The plastic material is usually different from the injection molding material, so as to form a multi-layered and diversified injection molding product. [0005] If the injection molded part is taken out of the mold and then placed into another mold for re-injection, two or more sets of different molds are required, and there are many process steps, complicated processes, fixed deviations, and a large amount of manpower and material resources. Many products, low production efficiency and other defects. Contents of ...
