Mold structure capable of achieving core pulling with arc-shaped inclined sliders

Abstract

The invention discloses a mold structure capable of achieving core pulling with arc-shaped inclined sliders. The mold structure comprises a movable mold and a stationary mold. A cavity is formed between the movable mold and the stationary mold. The movable mold comprises the inclined sliders, a movable mold frame, a movable mold bottom plate and a movable mold core fixing plate. The mold structure is characterized in that the inclined sliders are the arc-shaped inclined sliders with circular-arc-shaped bevel edges; the movable mold frame is provided with circular arc guide sliding grooves of which the circle centers coincide with the circle centers of the bevel edges of the arc-shaped inclined sliders; the radian of the circular arc guide sliding grooves is matched with the radian of the bevel edges of the arc-shaped inclined sliders; and push rods are also included and penetrate through the movable mold bottom plate and the movable mold core fixing plate, one ends of the push rods are in abutting joint with the lower end faces of the arc-shaped inclined sliders. Limiting grooves are formed in the circular-arc-shaped bevel edges of the arc-shaped inclined sliders, and the movable mold frame is provided with limiting pins corresponding to the limiting grooves. The effect that after the movable mold and the stationary mold are opened, the inclined slides can obtain large puling distance is guaranteed, so that core pulling is finished accurately, the action is stable and reliable, and the situations that tilting occurs suddenly and the side edges of the inclined sliders are damaged are not prone to occur. The mold structure is simple and low in manufacturing cost.

Description

technical field [0001] The invention relates to the structural technical field of metal die-casting molds and plastic injection molds, in particular to a mold structure for arc-shaped oblique slider core pulling. Background technique [0002] In the process of using metal die-casting molds and plastic injection molds to produce parts, when the forming or hole forming area on the side of the part is large, the form of slider guide should be used. However, when the side forming area is large and has a certain inclination angle, the existing inclined slider core-pulling mold structure needs to be designed with a larger slider inclination angle to obtain a corresponding drawing distance. However, if the bevel angle of the inclined slider is too large, it will easily cause a sudden inclination when the slider is pushed out of the workpiece, and the inclined slider is easily damaged. Contents of the invention [0003] In view of the above shortcomings, the present invention pro...
