Abstract

The invention provides a mold with an internal pulling structure. The mold comprises a stationary mold frame with a stationary mold core, and a movable mold frame which is slidably provided with an internal pulling block corresponding to the stationary mold core, wherein a product is ejected out without undercut through the relative movement between the stationary mold frame and the movable mold frame in the horizontal direction, and a wedging block which is slidably inserted into the movable mold frame is fixedly connected onto the stationary mold frame; an internal pulling driving block with a trapezoidal section is slidably arranged below the internal pulling block in the movable mold frame, and the internal pulling driving block is provided with a first driving connecting part which is provided with driving force for bearing the wedging block so that the internal pulling driving block slides when the wedging block slides in the movable mold frame; the internal pulling block is provided with a second driving connecting part which is provided with driving force for bearing the internal pulling driving block so that the internal pulling block slides when the internal pulling driving block slides. The internal pulling structural mold provided by the invention has the advantages of solving the problems of the existing mold with a three-plate mold structure, thus reducing the mold cost and improving the production efficiency of products.

Description

technical field [0001] The invention relates to the technical field of injection molds, in particular to a mold with an internal drawing structure. Background technique [0002] At present, the internal drawing mold of the front lampshade of the car mostly adopts a three-plate mold with secondary splitting. The three-plate structure includes a fixed platen, a movable platen and a spring plate. When the mold is opened, the fixed mold drives the movable mold to move together through the pull hook assembly. The spring plate and the wedge block move backward relative to the movable mold. The first time to open the mold. Then move and fix the mold and then separate to complete the second mold opening. The mold structure of the three-plate mold structure is complex, and the mold cost is relatively high, and because the mold opening requires secondary parting to complete the operation, the demoulding time is long, and the production cycle is also reduced, which is not conducive t...
