Description

A kind of injection mold for being provided with air cock
Technical field
This utility model is related to injection mold technical field, more particularly to a kind of injection mold for being provided with air cock.
Background technology
Mould is requisite instrument in injection mo(u)lding, and injection mo(u)lding is to heat the note of the plastic material of state from mould Modeling mouth is injected in having the closed die cavity of required form in mould, and after plastic material cooling and solidifying, opening mould will solidify Plastic ejection, the processing method to obtain shaped article.The processing method of injection mo(u)lding has molding low cost, molding cycle Short, forming process is simple, it is easy to the features such as forming shape complicated plastic, therefore the application in moulding process is extremely wide.
The problem that injection mold is present at present has:1st, during the demoulding, vacuum between punch and product contact surface, can be formed, if Air is introduced not in time, and the extraction of product can be caused difficult;2nd, the precision of injection is relatively low, affects the quality of product.
The content of the invention
The purpose of this utility model is to provide a kind of injection mold for being provided with air cock, can effectively solve the problem that punch with Vacuum is formed between product contact surface and causes the problem for being difficult to extract out, and by the flow-control to being molded, improving product Precision.
The technical solution adopted in the utility model is:A kind of injection mold for being provided with air cock, including it is convex dynamic model, recessed Shape cover half, the die cavity formed between dynamic model and cover half, mould emptier and it is arranged on the lower surface and dynamic model of dynamic model and is slidably connected Slide rail, the injection hole connected with die cavity is provided with the cover half, the mould emptier includes being arranged in the middle of dynamic model inner chamber The air cock of position and it is arranged on the transfer bar mechanism of the upper and lower both sides of air cock;The outlet side of the air cock be arranged on dynamic model with The convex surface end that die cavity contacts, the air cock are fixed in dynamic model by contiguous block, and the contiguous block is provided with and air The air flue of valve connection;The transfer bar mechanism includes the cushion chamber being arranged in dynamic model, and the buffering intracavity is provided with one end to be run through The push rod of cushion chamber, the other end of the push rod are connected with screw rod, and the screw rod drives push rod to slide in buffering intracavity.
Preferably, the injection hole feed end is provided with flow-control valve cell.
Preferably, heating wire is provided with the outside of the injection hole.
Preferably, the air cock is provided with sealing ring with the contact position of contiguous block.
Preferably, the screw rod is connected with drive motor, and the drive motor is connected with push pedal.
The beneficial effects of the utility model are:Air cock is fixed in dynamic model by contiguous block, and contiguous block is provided with and sky The air flue of air valve connection, storage in air cock are introduced to the air during demoulding by the air that air flue is entered, then by push rod Product is released and realizes the demoulding, vacuum is formed between effectively solving convex dynamic model and product contact surface and cause to be difficult to what is extracted out Problem.

Specific embodiment
The technical solution of the utility model is illustrated with embodiment below in conjunction with the accompanying drawings.
With reference to shown in Fig. 1, a kind of injection mold for being provided with air cock, including convex dynamic model 5, spill cover half 1, dynamic model 5 The die cavity that formed and cover half 1 between, mould emptier and the slide rail 13 that the lower surface and dynamic model 5 of dynamic model 5 are slidably connected is arranged on, The injection hole 10 connected with die cavity is provided with cover half 1, the outside of injection hole 10 is provided with heating wire 8,10 feed end of injection hole It is provided with flow-control valve cell 7.Mould emptier includes being arranged on the air cock 12 in 5 inner chamber centre position of dynamic model and is arranged on The transfer bar mechanism of air cock both sides about 12.The outlet side of air cock 12 is arranged on the convex surface end that dynamic model 5 is contacted with die cavity, Air cock 12 is fixed in dynamic model 5 by contiguous block 16, and air cock 12 is provided with sealing ring 2, institute with the contact position of contiguous block 16 State contiguous block 16 and be provided with the air flue 11 connected with air cock 12.Transfer bar mechanism includes the cushion chamber 4 being arranged in dynamic model 5, delays The push rod 17 that one end is provided with chamber 4 through cushion chamber 4 is rushed, the other end of push rod 17 is connected with screw rod 9, and screw rod 9 is connected with drive Dynamic motor 14, the drive motor 14 are connected with push pedal 6, and screw rod 9 drives push rod 17 to slide in cushion chamber 4.
The setting of heating wire 8 is to prevent the plastics for melting during injection hole 10 flows into die cavity because there is early solidifying shape As and cause the blocking of injection hole 10.
There is the situation that air is leaked to prevent air cock 12 and the junction of contiguous block 16 in sealing ring 2.
Operation principle of the present utility model:Convex dynamic model 5 shifts to spill cover half 1, convex dynamic model 5 and spill along slide rail 13 1 matched moulds of cover half, molten plastic enter die cavity from injection hole 10, control the injection rate of molten plastic by flow-control valve cell 7; After completing injection, convex dynamic model 5 resets to origin-location along slide rail 13, and air cock 12 starts to convex dynamic model 5 and finished product Concave contact face injects air, and drive motor 14 starts drive screw rod 9 and moves, and screw rod 9 drives push rod 17 to slide in cushion chamber 4 So as to product 3 is ejected.
