Background technology

Along with the continuous development of mould industry, Chinese mould of plastics development speed is quite fast for many years.At present, mould of plastics proportion in the entire die industry is about 30%.Along with domestic automobile; household electrical appliances; telecommunications and various building materials develop rapidly; expectation is in following mould market; the ratio that mould of plastics accounts for the mould total amount will progressively improve; and development speed will be faster than other moulds; ejecting mechanism is that each mould all needs the problem that solves in the product stripping; once ejecting after action finishes and run into some part through regular meeting, plastic still is difficult to the complete demoulding or can not freely falls or avoiding once ejecting the quality that the mode that all needs secondary release and compound release under the stressed excessive situation that causes the plastic distortion or damage meets design requirement and guarantees part.

It is one of difficult point of plastics mould design that the combined type secondary is released.And though but for example spring secondary commonly used ejects and simple in structurely moves unreliablely, spring lost efficacy easily; Though the rod-pulling type secondary ejects and moves reliably for another example, and pull bar has been installed on the fixed die, die size is increased, thereby increased the complexity of mould structure, to the cycle lengthening of installing and making, thus the cost increase.

In order to solve above-mentioned a series of problem, the utility model provides a kind of novel simple secondary composite liftout attachment, driving ejecting mechanism by the frictional force element that arranges moves simultaneously, realize compound ejecting, carry out secondary by stopping means again and eject, guaranteed that product can deviate from smoothly and avoid because once ejecting the stressed excessive damage of product that causes.Complex structure in the prior art, action is unreliable and cost is excessive problem have been solved.This is simple in structure, inside is compact, the die shape volume is little, has saved die cost, is applicable to the production that needs the plastic shaping product that secondary ejects.

Summary of the invention

The purpose of this utility model is to overcome the above problem that prior art exists, the compound ejecting device that provides a kind of simple secondary to eject, and the utility model is simple in structure, inside is compact, the die shape volume is little, saves die cost.
