Abstract

The invention relates to the technical field of molds, and provides a front mold core assembly and a three-plate mold. The front mold core assembly comprises a front mold core, a runner plate and a front mold insert; the front mold core is arranged in a mounting cavity of a plate A, and the front mold core is provided with a front mold cavity and a through hole communicated with the front mold cavity; the runner plate is movably arranged at the side, away from the front mold cavity, of the front mold core, and the runner plate is provided with a branch runner; and the front mold insert is arranged on the runner plate and penetrates through the runner plate and the through hole, a channel is formed in the front mold insert, one end of the channel is communicated with the branch runner, and the other end of the channel is communicated with the front mold cavity, wherein a first lock catch is arranged at the side, away from the front mold core, of the runner plate, and a first lock hole is formed in the side, close to the A plate, of a stripper plate. A product can be prevented from being adhered to the front mold insert and the front mold cavity, the product is prevented from being pulled to be damaged, damage of the mold due to damage of the front mold cavity can be prevented, and the normal and efficient production of the mold is ensured.

Description

technical field [0001] The invention relates to the technical field of molds, in particular to a front mold core assembly and a three-platen mold. Background technique [0002] The three-plate mold usually includes face plate, nozzle plate, A plate, B plate, ejector plate, fixed plate, etc. The front mold core is set in the A plate, and the rear mold core is set in the B plate. The front mold core and the rear mold core are matched. Form a cavity for product molding. [0003] In the three-plate mold, the product is easy to stick to the front mold insert when the injection molding is completed, especially when there are many and deep glue positions on the front mold core. Wrapping force, when the A plate and B plate are opened, the product will adhere to the front mold insert, which will easily cause the product to be strained; in severe cases, the product will stick to the front mold cavity, requiring a lot of labor It takes a lot of energy to remove the product; when it i...
