Combined type core pulling mechanism and combined type core pulling mold

Abstract

The invention provides a combined type core pulling mechanism and a combined type core pulling mold, and relates to the technical field of molds. The combined type core pulling mechanism comprises a fixed mold core, a movable mold core, a sliding block, an elastic core pulling insert, an inclined guide block and an inclined guide column. The fixed mold core and the movable mold core are oppositelyarranged, the sliding block is slidably arranged on the movable mold core, the inclined guide block is arranged on the fixed mold core and used for abutting against the sliding block, the inclined guide column is arranged on the inclined guide block and extends in the direction close to the movable mold core, a core pulling through hole is formed in the sliding block, and the elastic core pullinginsert is movably arranged in the core pulling through hole. Compared with the prior art, the combined type core pulling mechanism has the advantages that the core pulling action and the mold openingaction are simultaneously carried out, so that the injection molding period is shortened. The elastic core pulling insert and the mold opening force are used for replacing an oil cylinder to completethe core pulling and demoulding movement. The inclined top structure is removed, the risk of collision caused by insufficient resetting during production is avoided, and the safety of the injection molding process is greatly improved.

Description

Technical field [0001] The invention relates to the technical field of molds, and in particular to a combined core pulling mechanism and a combined core pulling mold. Background technique [0002] Existing product-specific end parts, such as the end forming structure of decorative strips, usually use oil cylinders to provide power, and the products are ejected through the inclined top. In the actual injection molding process of the product, after the inclined top ejects the product, Due to the instability of the production state, there is a risk of insufficient reset, resulting in the phenomenon of interference between the inclined top and the fixed mold core, and the risk of collision between components. In addition, in the prior art, the oil cylinder is used for movement first, and then the mold opening movement is performed, and the entire injection molding cycle is long. [0003] In view of this, it is particularly important to design and manufacture a safe and reliable combin...

Problems solved by technology

[0002] The existing end of the product, such as the end molding structure of the decorative strip, usually uses an oil cylinder to provide power, and the product is ejected through the inclined jack. In the injection molding process of the actual product, after the inclined jack ejects the product, Due to the unstable production status, there is a risk of insufficient reset, resulting in the phenomenon of interference between the inclined roof and the fixed mold core stroke, and there is a risk of collision between components

In addition, in the prior art, the movement of the oil cylinder is performed first, and then the mold opening movement is performed, and the entire injection molding cycle is long
