Description
Technical field
It the utility model is related to injection mold technology.
Background technology
Injection molding is to produce a kind of processing method used during some complex-shaped parts in batches, in particular to will be heated
The material of thawing injects die cavity by high pressure, after cooling and solidifying, obtains formed products.Injection mold is a kind of to produce plasthetics
Instrument, is also to confer to the instrument of plasthetics complete structure and accurate dimension, and injection mold divides into thermosetting according to shaping characteristic
Two kinds of plastic mould, thermoplastic plastic's mould, divided into according to moulding process and pass mold, blow molding die, draw mould, thermoforming mould, heat
Pressing mold, injection mold etc., wherein hot-die can be divided into excessive formula, semi-positive compression, three kinds of formula of not overflowing again in a manner of flash, and injection mold is by moving
Mould and cover half two parts composition, dynamic model are arranged on the moving die plate of injection moulding machine, and cover half is arranged on consolidating for injection moulding machine
In cover half fixed plate, in injection moulding, dynamic model forms running gate system and die cavity with cover half closure.Existing injection mold is in work
After part produces, it usually needs worker wears gloves and removes workpiece, therefore certain danger be present, and workpiece may have one with mould
Point adhesion, it is also not high with hand efficiency of taking, and be easily damaged.
Utility model content
The utility model is intended to provide a kind of mould of easy-unloading, is removed from the molds with solving workpiece in the prior art
Shi Rongyi scalds the problem of worker.
The mould of easy-unloading in this programme, including fixed half and moving half, dynamic model are located at the upside of cover half, the cover half with
Forming cavity is provided between dynamic model, the dynamic model is provided with the plug hole connected with forming cavity, and the bottom of the cover half is provided with vertically
Through hole, through hole connects with forming cavity, and the inside of through hole is provided with push rod, is provided with through hole and is used to support what push rod slided along through hole
Support, the upper end of push rod are installed with the block of reverse frustoconic, and the upper end of through hole is in the enlarging shape matched with block, under cover half
Side is installed with water tank, and the bottom of through hole is installed with conduit, and the lower end of conduit is installed with piston on the bottom of water tank, water tank
Pump, piston pump connect with the inside of water tank, and push rod is slidably connected through water tank and with tank seal, and the lower end of push rod is fixed limited
Position block, is provided with spring between limited block and water tank.
Through hole is set in this programme, for being moved for push rod, meanwhile, it is also used for introducing the water into forming cavity.Setting pushes away
Bar, for promoting block to move.Block is set, for being blocked to through hole, avoids plastics liquation from entering in through hole.Set
Conduit, for the water in water tank to be incorporated into through hole.Piston pump is set, air is poured in water supply case, makes in water tank
Pressure increases, so that water is entered in conduit.
Operation principle：After dynamic model and cover half matched moulds, plastics liquation is injected into forming cavity from plug hole and forms work
Part, when needing to take out workpiece, first dynamic model is separated with cover half, promotes push rod then up, make push rod drive block toward into
Moved in die cavity, so that block promotes workpiece movement, at the same time, control piston pump makes water tank toward air is injected in water tank
Interior pressure increase, so that the water in water tank is injected into through hole and entered in forming cavity by conduit, makes water promote work
Part moves, and finally workpiece is separated with cover half.After workpiece separates with cover half, control piston pump is inhaled to water tank inside
Gas, so that the pressure inside water tank reduces, the water in cover half is returned to by through hole in water tank, reuse water.
Compared with prior art, it is the advantages of this programme：1st, workpiece is released from cover half by push rod and water, makes work
Part separates with cover half, while when water contacts with workpiece, water can cool to workpiece, directly go to take with hand so as to avoid worker
Workpiece and the problem of be easily burned.2nd, by setting the block of reverse frustoconic, while the upper end of through hole is arranged to and kept off
The enlarging shape of Block- matching, when the block is contacted with through hole, there is no gap between block and through hole, so as to avoid plastics liquation stream
Enter in through hole.3rd, workpiece is promoted to be separated from cover half using water, because water is not easy to be compressed, so that water is promoting workpiece from calmly
When being removed in mould, the phenomenon that workpiece ejects from cover half suddenly will not occur, and then reduce the phenomenon hair that workpiece is damaged
It is raw.
Further, the block is threadedly coupled with push rod.When the situation of excessive wear occurs for block, it is convenient by block from pushing away
Under being dismantled on bar, so as to carry out quick-replaceable.
Further, the spring is tower spring.Spring is arranged to tower spring, the spring sky shared in compression can be reduced
Between, and then the occupancy in space can be reduced.
Further, the cover half is provided with positioning hole, and the alignment pin coordinated with positioning hole is installed with the dynamic model.Pass through
Positioning hole is set on cover half, alignment pin is set on dynamic model, facilitates dynamic model and cover half being capable of quick accurate matched moulds.
Further, the conduit is threadedly coupled with cover half, convenient that conduit is quickly mounted and dismounted.
