Description
Technical field
This utility model belongs to automobile die field, especially relates to a kind of mold ejection structure.
Background technology
After the molding in a mold of existing plastics part, the most upwards workpiece is ejected by thimble structure, as
Shown in Fig. 1, need the structure according to workpiece, multiple thimble is set in the lower end of workpiece, after Workpiece shaping, use thimble structure
Being ejected by workpiece, there is following problem in common thimble structure, and 1, owing to thimble is less with the contact area of workpiece, need
Being uniformly arranged multiple thimble, each thimble structure needs to carry out certain topology layout and design on mould, causes mould to be tied
Structure is complicated, relatively costly；2, thimble is less with the contact area of workpiece, and during ejecting, interface pressure crosses conference pair
Surface of the work produces certain impact, affects the qualification rate of product, is especially ejecting the product of thinner thickness, and this phenomenon is the brightest
Aobvious；3, thimble structure length is longer, and after processing, intensity is difficult to ensure, in mould produces motor process, is susceptible to stuck existing
As, inconvenient maintenance, affect work efficiency, the cycle of location maintenance is shorter, improves the maintenance cost of mould；4, thimble is being used
The when of ejecting, need to treat the complete molding of workpiece, eject again after plastic cement Stress Release is complete, it is to avoid workpiece is by thimble power
Amount produces stress and concentrates or deformation, extends the molding cycle of product, also reduces the efficiency of production to a certain extent.
Utility model content
It is simple that problem to be solved in the utility model is to provide a kind of processing, convenient maintenance and also can improving product qualification rate
