Abstract

The invention proposes an injection mold for efficient production of plastic parts with metal inserts, including a turntable with three stations, two lower half molds are placed on the turntable, and an upper mold fixing plate is arranged at the middle station of the turntable, and the upper mold is fixed. An upper half mold is fixed on the plate; the upper mold fixing plate is connected with the upper mold closing and separating mechanism, and the lower half mold is rotated at the side station of the turntable for the initial injection molding operation, and the lower half mold that has completed the initial injection molding is moved to the At the middle station of the turntable, the fixed plate of the upper mold moves upward to separate the upper half mold from the lower half mold; when the operator embeds the insert in the preformed plastic part in the lower half mold in the middle of the turntable, the upper mold is controlled to close. The sub-organization drives the fixed plate of the upper mold to move downward, so that the upper half mold and the lower half mold are closed, and the secondary injection molding is performed on the primary molded plastic part to fix the insert in the injection molded part. When the secondary injection molding of the middle station of the turntable , and the other lower half of the mold is used for initial injection molding at the side station of the turntable; this product can greatly improve the production efficiency of injection molded parts with metal inserts.

Description

technical field

[0001] The invention relates to the technical field of injection molding equipment, in particular to an injection mold for efficiently producing plastic parts with metal inserts. Background technique

[0002] In the electrical industry, due to the requirements of electrical safety regulations, it is often necessary to mass-produce products with metal inserts. Generally, enterprises make inserts first, then put the finished inserts into the injection mold, and cover the metal inserts with molten polymer plastic to complete the production of the product.

[0003] In the production of molds with embedded plastic parts, the most troublesome thing is that it takes a lot of time to place the inserts in the mold cavity, which leads to low efficiency in the production of products with inserts.

[0004] In this case, in order to solve the technical problem of low productivity with metal inserts, it is proposed to use an injection machine with a turntable. Completing...

Embodiment Construction

[0019] Such as Figure 1-3 As shown, the injection mold for efficiently producing plastic parts with metal inserts, the injection mold includes a turntable with three stations (one turntable middle station 103, two turntable side stations 104), and the turntable 105 is placed on the top There are two lower half molds 102, and an upper mold fixing plate 1 is provided at the middle station 103 of the turntable 105, and an upper mold fixing plate 1 is fixed with one upper mold half 101; the upper mold fixing plate 1 is connected with the upper mold closing and separating mechanism, The lower half-mold 102 is rotated at the side station 104 of the turntable to carry out the initial injection molding operation, and the lower half-mold after the initial injection molding is moved to the middle station 103 of the turntable by the turntable, and the upper mold closing and separating mechanism drives the upper mold fixing plate 1 upward. Move to separate the upper half mold 101 from th...
