Description
Technical field
A kind of mould structure is the utility model is related to, is moulded more specifically to a kind of threaded lid class of a multi-cavity mold
Part automatic threads demoulding mould structure.
Background technology
For many years, with the continuous development of mould industry, Chinese injection mold development is quite rapid, and injection mold is whole
Shared ratio more and more higher in die industry.Generally, when needing to be molded screwed plastic, its corresponding mould structure
It is more relative complex.Screw thread on plastic is divided into internal thread and external screw thread, and generally, internal thread is molded with thread core,
External screw thread is molded with Mold Ring with Screw Thread.According to the specific production requirement of different screw threads, the mould structure design of threaded portion is also
Difference, it is also different that it deviates from the mode of screw thread.On the premise of structure allows, the internal thread of working of plastics can be designed in segmentation
Screw thread, it is molded using slanted pushing rod inner core pulling.If it is desired to have complete internal thread, then its forming method mainly has following three
Kind：One, forced stripper mechanism, the method can be used when less demanding to Product Precision etc., be needed using this kind of stripping means
To use the preferable plastics of elasticity；Secondly, the outer hand-stripping of mould, thread core is made into movable insert, it is artificial outside mould to take out, this
Class mould structure is simple, but efficiency is low, and labor intensity is big, it is impossible to realizes automation；Thirdly, rotating mechanism automatic threads demoulding, should
Kind mould production efficiency is high, and labor intensity is small, easily realizes automation, suitable batch production.In the industrial production, most band
Threaded plastic all has required precision, such as plastic bottle closure, bottle cap to require water-tight after coordinating with bottle, and this is just to bottle
Lid own dimensions and accuracy of thread propose requirement, meanwhile, such product is typically all to produce in enormous quantities, for this kind of production
The method of the outer hand-stripping of product, forced stripper mechanism and mould is just no longer applicable.Moulded for the screw thread that size and structure etc. require
Part, manufacturer would generally be stripped using rotating mechanism.
At present, female mould emptier, such as number of patent application are set in many injection molds on the market
CN201310648147.7, data of publication of application is on April 9th, 2014, entitled：Plastic mold internal screw thread floating rotation stop takes off
Mold mechanism.This application case is related to a kind of plastic mold internal screw thread floating rotation stop mould emptier, including upper and lower compound plate, under upper compound plate
Solid plate is installed, support block is installed on lower compound plate, moving clamping plate, lower gear fixed plate, gear fixed plate, transition are installed on support block
Gear mounting plate and Bottom clamp plate, moving platen is installed on Bottom clamp plate, has die cavity between moving platen and solid plate, has production in die cavity
Product, product inwall set internal thread, fuse are threaded on moving clamping plate, and the head of screw thread fuse is engaged with internal thread,
Screw thread fuse is driven by gear-driven assembly by power to be rotated, and upper and lower top plate and thimble, the head of thimble are set between support block
It is in contact with the material handle after injection, described screw thread fuse outer wall sets rotation stop insert, and rotation stop insert is provided with rotation stop pin, only
Ship and resell on another market in sub- embedded product wall body bottom, floating spring is equipped with Bottom clamp plate, stopper slot is formed with moving platen, is set in stopper slot
Stop screw is put, stop screw connects Bottom clamp plate through floating spring.The mould emptier of this application case can be carried out easily
The demoulding, still, the mould emptier structure is complex, is driven not only production cost height by multi-stage gear, and it is passed
Dynamic distance is very limited, and when the output shaft of screw thread fuse and hydraulic motor is distant, need to set greater number of tooth
Wheel uses the gear being relatively large in diameter, very inconvenient.Meanwhile the mould emptier is not provided with stopping means and plastic is moved axially
Position is limited, and the tail tooth of plastic is easily pulled in the demoulding, causes unnecessary loss.In addition, the mould emptier relies on
Thimble is withstood on plastic material handle, so as to which by outside plastic ejection die, it is unreliable that this kind of mode ejects, and easily pulls plastic during ejection
Screw thread.
