Problems solved by technology
[0002] At present, in the process of mold production, some products have higher requirements. For example, when the product is covered with metal pins, the product only allows the terminals to be exposed to the outside of the product (the first metal terminal covered with plastic can connect multiple terminals into one part. function); the product has a salt spray test waterproof requirement that no water can leak, and the primary rubber insert and plastic parts cannot be exposed, otherwise the side parts will conduct electricity and cause the parts to be scrapped
(For car door lock parts, the existing molds cannot meet the requirements except for the exposed part of the terminal, and the rest cannot be completely wrapped with secondary rubber-coated plastic, which cannot guarantee seamless gaps, and there is a great risk of water seepage, which will cause car door locks to fail. risks of

The invention relates to the field of rubber coating plastic part molds, in particular to a rubber coating plastic part suspension mold. The suspension mold comprises a primary rubber coating insert,a secondary rubber coating mold, a movable mold pressing needle and a fixed mold pressing needle; the primary rubber coating insert is erected in the secondary rubber coating mold, and secondary rubber coating mold is located between the movable mold pressing needle and the fixed mold pressing needle; and the movable mold pressing needle has a one-to-one correspondence with the fixed mold pressingneedle, the movable mold pressing needle is provided with a first driving mechanism for driving the movable mold pressing needle to move, and the fixed mold pressing needle is provided with a seconddriving mechanism for driving the fixed mold pressing needle to move. According to the suspension mold, the primary rubber coating insert is suspended in the secondary rubber coating mold, so that theprimary rubber coating insert can be ensued not be exposed.
