Material applies high pressure to molten plastic, it is made to project and be full of mold cavity.
The working principle of injection molding machine is similar to the syringe having an injection, it is by screw rod（Or plunger）Thrust, will
The molten condition being plasticized（That is viscous state）Plastic injection enter in the die cavity being closed, after cured sizing obtain product work
Skill process.
Injection moulding is the process of a circulation, and each period mainly includes：Quantifying feed-fusion plastification-pressure note
Penetrate-mold filling cool down-opens mould pickup.Die closing again again is taken out after plastic, next circulation is carried out.
Referring to attached drawing 1, injection mold is generally made of two parts, respectively fixed mold 2 and moving mold 1, the mould of fixed mold 2
Tool inner cavity 22 and the inner cavity 11 of moving mold 1 are built into the inner mold chamber of mold jointly.It is provided on fixed mold 2 and is injected for liquid castable
Entrance 21. use when cover half 2 be fixed.
In knockout course, dynamic model 1 is disengaged from cover half 2, then takes out the molded part in the inner mold chamber of mold.
For castable during cooling and solidifying, volume has portion retracts, therefore, the appearance meeting of the molded part after solidification
Automatically it is mutually removed with mold, the process very comfortable of demoulding.
In the production of reality, after dynamic model 1 is disengaged from cover half 2, molded part may be rested on cover half 2, it is also possible to
It rests on dynamic model 1, is not easy to directional collecting.The equipment that the prior art also has dedicated for collecting molded part, but due to dynamic
The spacing of the two is larger after mould 1 is mutually disengaged with cover half 2, and collecting device needs both sides to collect, therefore, the span and volume of equipment
It is all very big；Collecting device also needs to have the function of detecting molded part position, and the complexity of equipment is high, and the reliability of equipment is low.
Utility model content
The purpose of this utility model is to provide a kind of injection molds, to solve the problems, such as to mention in above-mentioned background technique.
To achieve the above object, the utility model provides the following technical solutions：A kind of injection mold, including cover half and dynamic

On the end face of linear bearing.It is further preferred that being provided with a drain spout on the pedestal, the drain spout is provided with dynamic model
On position between bracket and cover half.
When pulling plate is taken to linear bearing front end, pulling plate can be touched simultaneously stops travel switch and reverse stroke switch,
Stop being formed switching and can interrupt the movement of dynamic model driving hydraulic cylinder, reverse stroke switchs meeting so that air pump reversely rotates, and air pump is by taking out
Gas becomes being vented, and under the positive pressure of exhaust, molded part can fall off from dynamic model, and the molded part to fall off can fall into drain spout,
Only a collection bucket or conveyer belt, which need to be divided into, in drain spout at this time can be completed and collect work to molded part.
To sum up, the technological merit of the utility model is：
（1）In demoulding, molded part can follow dynamic model to synchronize and leave cover half the utility model, therefore can be in dynamic model to orientation
Collect molded part.Molded part is the random distribution on dynamic model and cover half the case where compared to the prior art, the utility model more added with
Conducive to the collection of molded part, it is also beneficial to the miniaturization of mating collecting device, is located on dynamic model since molded part is fixed, does not need
Collecting device has position detecting function, and the structure of collecting device is simplified.
（2）In the preferred embodiment of the utility model, air pump can be with adsorption forming part, air pump reversion exhaust when rotating forward pumping
The stripping off device of molded part can be done, is fallen after molded part removing from drain spout, completes the collection to molded part.The preferred embodiment
In, do not need the collection equipment of other mating molded part.The prior art needs this mating collection equipment, therefore the utility model has
Have from collecting function, saves equipment investment.
