Problems solved by technology
[0004] The above-mentioned existing technical solutions have the following defects: during the use of the two-color injection mold, after the first injection, the subsequent mold of the product is rotated 180 degrees together and transferred to another part of the front mold; then the front and rear molds are closed, Driven by the oil cylinder fixed on the front mold, the core of the front mold is pushed forward, and the sliders of the front mold are closed, but the connection stability between the front and rear molds is relatively poor

The invention relates to a two-color injection mold, which includes a front mold and a rear mold facing each other. A positioning mechanism is arranged at the abutting position of the front mold and the rear mold. The positioning mechanism is separately arranged on opposite sides of the two-color injection mold. The travel mechanism includes a first row assembly and a second row assembly arranged at intervals. Both the first row assembly and the second row assembly include locking blocks and elastic members. The first row assembly is also provided with a second row assembly. A limit rod, the second row component is provided with a second limit rod; the locking block is slidably arranged on the rear mold and the middle position of the locking block is provided with a row slot, and the elastic member is inserted in the row slot The opposite sides of the inner wall are slidingly connected with the locking block; the first limit rod and the second limit rod are inserted in the row position and form a clamping connection with the locking block. effect on connection stability.
Description
technical field [0001] The invention relates to the technical field of injection molds, in particular to a two-color injection mold. Background technique [0002] Two-color injection mold refers to the combination of two different colors and different types of plastics, most of which are a soft plastic and a hard plastic, and are injected in a certain order by a two-color injection molding machine, so that the two plastics are organically combined. , to become a complete product, the two-color injection mold is the necessary equipment for the above injection molding process. [0003] The existing Chinese patent with reference number CN101096121B discloses a two-color injection mold, including a front film, a rear mold, a plurality of sliders positioned at the front mold and a plurality of sliders positioned at the rear mold, and multiple a first cavity, a plurality of second cavities, a first hot runner, a second hot runner, at least one first auxiliary runner and at least ...
