Description
Technical field
It the utility model is related to injection mold technology, more particularly to a kind of inflatable body of injection mold.
Background technology
At present, when producing the plastic product of similar containers, the structure of traditional injection moulding mould is typically that the core of mould is stretched
Enter product inwall, the die cavity of mould is coated on product outer wall, and the gap between core and die cavity forms the die cavity of product.In product
After injection molding, because die cavity is coated on the outer wall of product, in the presence of die cavity coats power, when mould molds, plastics production
Product can be usually stayed in the strong chamber of mould, and the cavity side in mould does not install liftout attachment typically, therefore, can cause product card
It mould, can not automatically deviate from, such as handle not in time, easily cause mould that mechanical breakdown occurs, influence to produce.
The content of the invention
A kind of the defects of the purpose of this utility model is to be directed to above-mentioned prior art, there is provided air feeder of injection mold
Structure, avoid when product is stayed on core, act and run with core die sinking, the defects of product snap gauge occurs, product is smoothly ejected,
This is reasonable in design, simple in construction, reliability is high.
To achieve these goals, the technical solution of the utility model is：
A kind of inflatable body of injection mold, including solid plate, moving platen, the type being arranged between solid plate and moving platen
Chamber, the die cavity lower section are tiltedly provided with pressure channel, and the pressure channel is connected with inlet channel, and the inlet channel is connected with gas
Source；The sliding pin that can be slided in pressure channel is provided with the pressure channel and acts on the rack core of sliding pin,
The solid plate, moving platen are equipped with driving rack that can be up and down in solid plate, moving platen, the rack core with
Axle with teeth is set between driving rack, and the driving rack is connected by tooth axle and rack core；When the mold cavity forming,
The sliding pin blocks inlet channel, and now, the end face of sliding pin turns into a part for forming surface；When moulding is concluded, it is described
Driving rack acts, and is acted by tooth axle and rack core, sliding pin is got out of the way inlet channel, source of the gas is supplied gas, and passes through pressure
Passage blows afloat product upwards, makes article removal, and before be molded next time, driving rack does opposite action, and sliding pin resets, can be with
It is molded next time.
As the improvement to above-mentioned technical proposal, all portions of the sliding pin are arranged with back-moving spring.
As the improvement to above-mentioned technical proposal, cylinder, the driving rack and gas are provided with below the driving rack
The piston connection of cylinder.Cylinder action slides up and down driving rack in driving rack.
Compared with prior art, the utility model has the advantages and positive effects of：
The inflatable body of injection mold of the present utility model, avoid when product is stayed on core, act and transport with core die sinking
OK, the defects of product snap gauge occurs, product is smoothly ejected, this is reasonable in design, simple in construction, reliability is high.
Brief description of the drawings
, below will be to embodiment in order to illustrate more clearly of the utility model embodiment or technical scheme of the prior art
