A self-locking slider structure for two-color molding

Abstract

The invention belongs to the technical field of injection molds for automobile lamps, and provides a double-color molding self-locking slider structure. By the aid of the double-color molding self-locking slider structure, the technical problem of difficulty in using oil cylinders for medium and small molds due to large occupied spaces of the oil cylinders when self-locking functions of sliders are implemented by means of oil cylinder driving can be solved. The double-color molding self-locking slider structure comprises a slider body, a pull block, a triangular seat, a guide device, a limit device, self-locking devices and a driving device. The slider body, the pull block and the triangular seat are matched with one another by the aid of a T-shaped block, guide actions can be completely carried out, the limit device is arranged on the pull block, and accordingly accurate movement distances of the pull block can be guaranteed; shifting blocks are arranged on the driving device and areused for driving the pull block to move when molds are closed or opened, and elastic self-locking blocks are arranged on oblique wedges of the driving device and are used for locking the pull block when the molds are closed. The double-color molding self-locking slider structure has the advantages that the oil cylinders are replaced with double-color molding structures, accordingly, the cost can be reduced, the reliability of mechanisms can be improved, the requirements of structural designs under the condition of small spaces can be met, the service range can be greatly expanded, and the service lives of the molds can be prolonged.

Description

technical field [0001] The invention belongs to the technical field of injection molds for automobile lamps, and in particular relates to a self-locking slider structure for two-color molding. Background technique [0002] At the current stage of the rapid development of the mold industry, people are trying to innovate a more reliable and effective mold structure, which can realize the smooth release of the product and minimize the defect of the product. The slider is a frequently used structure in mold design, especially the slider structure that can realize two-color molding. The use of ordinary sliders, secondary sliders and inner mold sliders makes the structure of the mold more abundant, and the mold tends to be more high-end. [0003] At present, there are many structures that can realize two-color molding sliders, such as using an oil cylinder to control the movement of the slider, or using an inclined guide post to drive the slider, etc., but these structures tend t...
