Self-adaptive damping type slow draft device

Abstract

The invention discloses a self-adaptive damping type slow mold pulling device which comprises a relative dynamic and static double-model damping automatic adjusting device, an anti-rotation-blocking pulling force gradually-increasing type mold locking device, a main body telescopic guide mechanism and a cable rope type constant-power driving mechanism. The invention belongs to the technical field of demolding auxiliary devices, and particularly relates to a self-adaptive damping type slow demolding device. According to the pre-tightening type anti-impact mechanism, a pre-compressed anti-impact spring is arranged at the demolding position, and it is guaranteed that a flexible and anti-impact structure with enough supporting force can prevent the lifting mechanism from bouncing at the moment of demolding; through the relative dynamic and static double-model damping automatic adjusting device, the technical target that when the resistance is suddenly reduced, the upper die can move upwards and cannot bounce upwards quickly is achieved in the mode that an anti-impact spring is compressed in advance and the sliding resistance of a damping piston ring is adjusted in a self-adaptive mode through viscous fluid.

Description

technical field [0001] The invention belongs to the technical field of demolding auxiliary devices, in particular to an adaptive damping type slow die-pulling device. Background technique [0002] A mold is a tool used to make a molded article. It is generally composed of at least two hollow shells. There is a cavity in the middle of the shell. Fluid is injected into the cavity. After the fluid solidifies, the shell is opened to obtain a molded product. ;The most common mold is composed of upper and lower molds. The molds are positioned by pins and connected by bolts. The inner cavity of the mold is designed with a draft angle, which is easy to demould. The common demoulding method is to fix the lower mold in On the bottom plate, an upward force is applied to the upper mold to separate it from the product, and then the product is taken out from the lower mold by hoisting the product. [0003] The demolding process of the mold is relatively mature, but there are still the fo...

Problems solved by technology

[0008] E: The demoulding and separation action is completed in an instant. Before the demoulding, the mold has no displacement. Therefore, if the motor and the mold are directly connected, the motor needs to quickly increase the torque to complete the demoulding. Compared with slow rotation and slowly increasing torque As far as the motor is concerned, this way of working has a greater load on the motor, which is more likely to cause the motor to overheat and reduce its lifespan.
