The die comprises a moving template and a base, wherein the middle part, far away from the base end, of the moving template is provided with a cavity insert connected with a workpiece cavity, and the middle part of the workpiece cavity is provided with a mold core simultaneously passing through the cavity insert; the base end of the moving template is provided with a push rod base, the bottom of the push rod base is provided with more than two rollers, each roller is connected with a rotating rod, the free end of each rotating rod is connected with a push rod, the free end of each push rod is connected to the bottom of the workpiece cavity, and the push rods are uniformly distributed at the bottom of the workpiece cavity and two sides of the mold core. The die has the advantages of less effort for pushing out, reduced frictional force, no workpiece damage and high demolding efficiency because of demolding through translating and pushing out according to the characteristic of the inclined thread structure, and also has the advantages of simplicity in design, raw material saving, convenience in use, increased service efficiency and prolonged service life.
Description
Technical field
The utility model relates to injection mold field, particularly a kind of mould that is applicable to have the demoulding of oblique helicitic texture workpiece.
Background technology
injection mold is widely used in processing, the moulding of plasthetics, yet the workpiece in processing with oblique helicitic texture, as screw, nut, helical gear etc., because its tooth trace is helix, profile of tooth is with the helical angle of certain angle, after working of plastics injection moulding, conventional release mode cannot realize the working of plastics demoulding, when requiring ejecting mechanism to press stripping direction release, the direction that the die cavity of moulding profile of tooth or plastic beveled wheel itself tilts by profile of tooth is rotated, and can reach the object of the smooth demoulding.Especially to plastics duplex helical gear, during the demoulding, except solving the problem of the rotation of profile of tooth die cavity or the rotation of gear working of plastics, also need to solve the demoulding difficulty causing because two helical gear " pitch " is different.
The stripping means of existing such injection mold is mainly forced stripper mechanism, but the method is only applicable to, working of plastics raw material have better toughness, gear helical angle is little and the occasion of profile of tooth thinner thickness.Because required release power is larger, crooked for avoiding working of plastics distortion or releasing element, release the general mould of sectional area ratio larger of element (push rod or ejector sleeve).
