A corner core pulling method and device for mold casting

Abstract

The invention discloses an angle core pulling method and device for die casting. When being used, the angle core pulling device for die casting is arranged in a die, and then is pulled out after die casting. The device comprises a core pulling component, a driving sliding block and an oil cylinder, wherein the top end of the core pulling component contacts with a die casting component for core pulling; the driving sliding block is used for driving the core pulling component to move; the oil cylinder is arranged at one end of the driving sliding block to provide power. The device are characterized in that the driving sliding block is arranged below the core pulling component, wherein inverted T-shaped sliding chutes forming angles with the horizontal direction are formed in the end parts of the driving sliding block; an inverted T-shaped sliding block which can be matched with the inverted T-shaped sliding chutes in an embedding manner is formed at the bottom of the core pulling component. According to the method and the device, the problems of excessively large die size caused by the conventional core pulling device design and requirement on a large-tonnage die casting machine due to the excessively large die size under the condition that the middle of the die has core pulling requirement during die casting are solved; by the angle core pulling device, the inner idle space of the die is fully utilized, and the whole die is more compact; in addition, the requirements of vehicle bodies on personalized shapes are met.

Description

technical field [0001] The present invention relates to the field of mold casting, in particular, the present invention relates to a method and device for corner core-pulling for mold casting, and the corner core-pulling device for mold casting is pulled out after mold casting, more specifically, the present invention relates to a A novel corner core-pulling method and device for mold casting, the corner core-pulling method and device for mold casting are especially used for mold casting of automobile lamps. Background technique [0002] In the past, for the case where core-pulling is required in the middle of mold casting parts, for example, when it is necessary to form specific grooves, edges and other concave-convex structures and additional components on the mold casting parts, the traditional method is to use external core pulling device or inclined roof structure. [0003] The outer core-pulling device requires more mold space, while the inclined top structure is only...
