Rear cover casting positioning and forming die and forming and processing method

Abstract

The invention discloses a rear cover casting positioning and forming die and belongs to the technical field of rear cover casting positioning and forming dies. A die casting groove adapted to a die core is formed in the center of the top of a lower die; a process step is formed in the outer side of the top of the lower die; positioning holes, adapted to positioning columns respectively, are formedin the left side and the right side of the top of the lower die respectively; the outer wall of the lower die is fixedly provided with a water cooling ring; the top of the base is fixedly provided with a water tank; the left side and the right side of the top of the water tank are fixedly provided with a cooling water pump and a backflow water pump respectively; a water inlet pipe and a backflowpipe which are fixedly connected with the water cooling ring are fixedly assembled on the cooling water pump and the backflow water pump respectively; the side walls of the opposite sides of the two groups of brackets are fixedly provided with discharging electric telescopic rod groups respectively; and gripper devices are fixedly assembled on the discharging electric telescopic rod groups respectively. The rear cover casting positioning and forming die can achieve the accurate positioning effect during workpiece blanking, can enable the die casting precision of a workpiece to be higher and improves the precision of a product.

Description

technical field [0001] The invention relates to the technical field of positioning and forming molds for back cover castings, in particular to a positioning and forming mold for back cover castings and a forming processing method. Background technique [0002] The mold is a tool that makes the blank into a workpiece with a specific shape and size under the action of external force. It is widely used in blanking, die forging, cold heading, extrusion, powder metallurgy parts pressing, pressure casting, and engineering plastics, rubber, ceramics, etc. In the forming process of compression molding or injection molding of other products, the mold has a specific contour or inner cavity shape. The existing back cover casting processing mold directly uses the upper and lower molds for stamping and forming. For some products with high precision requirements, the dynamic and fixed After the mold has been closed and opened for many times, there will be deviations in the cooperation bet...

Problems solved by technology

[0002] The mold is a tool that makes the blank into a workpiece with a specific shape and size under the action of external force. It is widely used in blanking, die forging, cold heading, extrusion, powder metallurgy parts pressing, pressure casting, and engineering plastics, rubber, ceramics, etc. In the forming process of compression molding or injection molding of other products, the mold has a specific contour or inner cavity shape. The existing back cover casting processing mold directly uses the upper and lower molds for stamping and forming. For some products with high precision requirements, the dynamic and fixed After the mold has been closed and opened for many times, there will be deviations in the cooperation between the movable mold core and the fixed mold core, resulting in a decrease in product accuracy, and the product will be scrapped directly, or the product can only meet the precision requirements through secondary processing. This increases the production cost and reduces the production benefit. Moreover, due to the low cooling rate of the casting, the molding speed of the casting is slow and the work efficiency is not high. After the casting is completed, it may be attached to the inside of the mold, which is not easy to release the mold, which seriously affects the work efficiency, for this reason, we propose a back cover casting positioning forming mold and forming processing method
