the push rod 18 extends to one side and drives the side push plate 17 to be separated from the side push plate groove 171, and the side push plate 17 pushes and releases the outer edge of the injection molding piece on the inner mold 13 in the ejection process because the side push plate 17 is flush with the outer wall of the inner mold 13;
In the pushing process of the side pushing plate 17, the machine body 1 controls the external compressed air pump device to convey compressed air into the air pipe main excitation rod 22, meanwhile, the pushing block 21 is communicated with and pushes the air pipe main excitation rod 22 to move, in the moving process of the air pipe main excitation rod 22, the air pipe main excitation rod 22 applies pushing force to the compression spring 24 arranged on one side, and due to the supporting arrangement of the resistance spring 241 on the other side, the compression spring 24 deforms and compresses and enables the air inlet pipe 26 arranged in the air pipe main excitation rod 22 to move in the branch excitation rod 221, wherein the air inlet pipe 26 horizontally moves in the air chamber guide channel 30 arranged in the branch excitation rod 221 under pushing action, one side of the air inlet pipe 26 is respectively connected with the exhaust pipe 28, the trigger thimble 29 and the sealing head 31, after the air inlet pipe 26 drives the sealing head 31 to move to a certain distance, the sealing head 31 stretches out of the air chamber guide channel 30 and penetrates into the air chamber 25 communicated with the air chamber guide channel 30, and because the cross-sectional area of the air chamber guide channel 30 is different from the air chamber 25, the compressed air passes through one side of the sealing head 31 and enters the air chamber 25 and passes through the plurality of air outlet holes 16 arranged in the air chamber 25;
Simultaneously, in the promotion in-process of tuber pipe owner excitation pole 22, branch excitation pole 221 can continuously move and arouse the venthole 16 and give vent to anger in the removal process, simultaneously tuber pipe owner excitation pole 22 can with branch excitation pole 221 extrusion contact, the compression spring 24 of this moment has compressed to the limit, and resistance spring 241 carries out compression deformation in the promotion in-process, and because branch excitation pole 221 carries out ejecting through tuber pipe owner excitation pole 22, branch excitation pole 221 drives the stripper plate 14 of one side and breaks away from in the drawing of patterns groove 131 that interior module 13 middle part was seted up, and carry out the roof pressure to the injection molding of shaping on the interior module 13, and because the both sides of injection molding have carried out the pre-demoulding through side push pedal 17, the injection molding carries out the rapid demoulding under the effect that compressed gas spouted, stripper plate 14 released at this moment, and then can effectively prevent the moulded body warp in the process of breaking away from the mould, thereby improved the precision and the quality of shaping object.
In the practical application process, compressed gas enters the air chamber guide channel 30 formed in the middle of the branch excitation rod 221 through the air channel 261 formed in the main excitation rod 22 and the air inlet pipe 26 of the air pipe.
In the practical application process, the push block 21 extrudes the main spring 23 arranged on the push block support rod 20 in the demolding process, and generates a rebound force to meet the reset function after the demolding is finished.
In the practical application process, the side pushing plate 17 is used for demolding the edge of the injection molding part preferentially, so that deformation or damage of the injection molding part in the demolding process can be prevented.
In the invention, the push rod 18 drives the side push plate 17 to extend out in the demolding process so as to demold the edge of the die, and the side push plate 17 is excited by the main excitation rod 22 of the air pipe, the branch excitation rod 221, the spring component and other structures, the demolding plate 14 in the inner mold 13 extends out and demolds the middle part of the die, and when the demolding plate 14 is excited and pushed out, the front top of the ejector pin 29 is triggered to excite and introduce compressed gas to assist in demolding, compared with the traditional demolding mechanism, the mechanism has the advantages that the demolding sequence is set, and compressed gas is additionally introduced in the demolding process to assist in demolding, so that the demolding efficiency is effectively improved, the stability is high, the functionality is perfect, the demolding of complex dies can be effectively satisfied, the operation quality is improved, and the molding precision is increased.
Meanwhile, due to the arrangement of the inner module 13 and the outer module 12, the mold is convenient and fast to replace later, the molding quality in the cavity is stable, and the integrity of the inner wall and the outer wall of the injection-molded mold is high.
The foregoing is only a preferred embodiment of the present invention, but the scope of the present invention is not limited thereto, and any person skilled in the art, who is within the scope of the present invention, should make equivalent substitutions or modifications according to the technical scheme of the present invention and the inventive concept thereof, and should be covered by the scope of the present invention.
