Plastic die for stamped part

Abstract

The invention discloses a plastic die for a stamped part. The plastic die comprises an operation plate, an operation frame is fixedly connected to the top of the operation plate, a hydraulic oil cylinder is fixedly connected to the top of an inner cavity in the operation frame, a movable plate is fixedly connected to the output end of the hydraulic oil cylinder, an upper die is fixedly connected to the bottom of the movable plate, and the top of the operation plate is movably connected with a lower die used in cooperation with the upper die. According to the die, by means of a water pump, a liquid inlet pipe, a liquid feeding pipe, a cooling bin, the lower die, a conveying pipe, a fixing frame, rotating rods, fan blades, driving motors, cooling fins, a circulating pipe and cooling siliconegrease, the die can achieve the function of good cooling effect, and the problems that a plastic die in the existing market do not have the function of good cooling effect in stamping production, thelong-time stamping operation temperature of the die is high, the die is prone to deforming after being heated, and therefore, the product stamping quality is influenced, and the use by a user is inconvenient are solved.

Description

technical field [0001] The invention relates to the technical field of plastic molds, in particular to a plastic mold for stamping parts. Background technique [0002] The mold is a precision tool with a complex shape and bears the swelling force of the billet. It has high requirements for structural strength, stiffness, surface hardness, surface roughness and machining accuracy. The development level of mold production is one of the important symbols of the level of mechanical manufacturing. At present, with the continuous improvement of social productivity and the strict requirements of the market for product quality, the qualification standards of various products are also constantly improving and changing, and various industrial processing machinery and equipment are also constantly being upgraded. Therefore, in order to improve the quality of processed products, the use of various molds is crucial. [0003] When using plastic molds for stamping operations, there are th...
