Description
[technical field]
The present invention relates to injection mold more particularly to a kind of injection molds of plastic elbow.
[background technology]
Injection molding is the processing method for producing certain complex-shaped plastic components in batches, and injection mold is injection molding production modeling
The mold of glue product.Injection mold is made of dynamic model and cover half two parts, and dynamic model is mounted on the moving die plate of injection (mo(u)lding) machine,
Cover half is mounted on the fixed form of injection (mo(u)lding) machine.In injection moulding, dynamic model is closed with cover half constitutes running gate system and type
Chamber, dynamic model and cover half separation are to take out plastic products when die sinking.In order to ensure dynamic model and cover half in molding can accurately in,
It must be provided with guiding parts in a mold.Four groups of guide posts of generally use form guiding parts with guide sleeve in injection mould, sometimes
The inside and outside conical surface that matches mutually need to also be respectively set on dynamic model and cover half carrys out auxiliary positioning.For carrying that side is recessed or side opening
Plastic products must first carry out undercut before being pushed out, and can smoothly demould after extracting side core_pulling out, need at this time
Side core-pulling mechanism is set in mold.
The prior art produces plastic elbow using injection mold, when carrying out core_pulling demoulding to elbow fuse, due to elbow
Have at barb, be generally adopted by the twice core pulling mode for being oriented to skewback and barb fuse and the combination of elbow fuse, but
When core pulling, being oriented to skewback and barb fuse can beat, and when being oriented to skewback with the reset of elbow fuse, it is to utilize to be oriented to skewback
The case where spring is resetted, and elbow fuse is to be driven to reset by core pulling oil cylinder, and there are asynchronous resets, is easy to encounter cavity
Cavity damages cavity.
The utility model patent of Patent No. CN201220681034.8 discloses a kind of interior pumping of plastic elbow mould pull rod
Mechanism includes the cavity on mold mould bases, elbow fuse is arranged in the cavity of cavity, elbow fuse is by core pulling oil cylinder band
