Based on the embodiments in the utility model, all other embodiments obtained by those skilled in the art without creative labor fall within the protection scope of the utility model.

[0027] With reference to Figures 1-6 , the utility model provides an embodiment:

[0028] A front and rear mold ejection injection mold frame, including front mold frame 1 and rear mold frame 2, a plurality of springs 12 are fixedly arranged in the inside one side of front mold frame 1, a plurality of springs 12 one side between fixedly arranged with front connecting plate 13, front connecting plate 13 one side fixedly arranged with front ejection plate 11, front ejection plate 11 one side fixedly arranged with a plurality of fixed rods 8;

[0029] Rear mold frame 2 inside one side close to front mold frame 1 is slidably arranged with rear connecting plate 14, rear connecting plate 14 one side close to front mold frame 1 is fixedly arranged with rear ejection plate 7, rear mold frame 2 outside both ends are fixedly arranged with two cylinders 4, a plurality of cylinder 4 output ends are fixedly arranged in the outside both ends of front mold frame 1, rear mold frame 2 both ends are fixedly arranged with connecting block 3, two connecting blocks 3 upper and lower ends are fixedly arranged with nozzle 5;

[0030] The front mold frame 1 is fixedly provided with fixed blocks 9 at both ends, the two fixed blocks 9 are slidably arranged in the inside of the connecting block 3 respectively, the front connecting plate 13 is slidably arranged in the inside of the front mold frame 1 away from the rear mold frame 2, the front ejection plate 11 is slidably arranged in the inside of the front mold frame 1 close to the rear mold frame 2, the plurality of fixed rods 8 are slidably arranged in the inside of the rear connecting plate 14 respectively, the rear ejection plate 7 is slidably arranged in the inside of the rear mold frame 2 close to the front mold frame 1, a plurality of guide holes 10 are arranged on one side of the front mold frame 1, a plurality of guide columns 6 are fixedly arranged on the side of the rear mold frame 2 close to the front mold frame 1, the plurality of guide columns 6 are slidably arranged in the guide holes 10 respectively, the plurality of fixed rods 8 are slidably arranged in the inside of the rear mold frame 2 close to the front mold frame 1, the front mold frame 1 is arranged on the side of the rear mold frame 2 close to the front ejection plate 11, the front mold frame 1 is parallel to the rear mold frame 2, and the rear ejection plate 7 is parallel to the front ejection plate 11;

[0031] Specifically, when the front and rear ejection demolding process is performed by using the injection mold frame, as the rear mold frame 2 gradually separates from the front mold frame 1, the extrusion force of the rear mold frame 2 on the front ejection plate 11 and the front connecting plate 13 gradually weakens, at this time, the plurality of springs 12 arranged in the inside of the front mold frame 1 begin to play a role, the front connecting plate 13 is smoothly pushed to slide in the inside thereof, and then the front ejection plate 11 is driven to perform the ejection action, when the front connecting plate 13 slides to the preset final position, the movement of the rear mold frame 2 does not stop, but continues to move backward, in this process, the rear connecting plate 14 smoothly slides along the outer wall of the fixed rod 8, when the rear mold frame 2 moves to a certain specific position, the rear connecting plate 14 and the rear ejection plate 7 thereon begin to slide in the inside of the rear mold frame 2, and then the rear ejection plate 7 pushes the molded mold part, so that the automatic demolding is completed, through the assistance of the front and rear mold frames 2 and the springs 12, the rapid and stable ejection of the mold is realized, the demolding efficiency is improved, the whole demolding process does not need manual intervention, the high automation is realized, the labor cost is reduced, the overall efficiency of the production line is improved, and the mold part is uniformly stressed in the demolding process, so that the surface quality of the demolded product is stable, the defective rate is reduced, and the mold is more convenient to maintain and adjust, and the downtime is reduced;

[0032] In the mold closing process, the rear mold frame 2 steadily approaches the front mold frame 1, prompting the air cylinder 4 to gradually contract, and as the air cylinder 4 contracts, the gas accumulated inside is orderly guided to the connecting block 3 and finally forcefully sprayed out through the nozzle 5, not only effectively cleaning the surfaces of the front mold frame 1 and the rear mold frame 2, ensuring the cleanliness of the mold, and effectively removing impurities and residues, laying a solid foundation for high-quality molding, but also, the connecting block 3 flexibly slides outside the fixed block 9 at both ends of the front mold frame 1, while the guide column 6 accurately embeds into and slides in the guide hole 10, providing solid guiding support for the accurate alignment of the mold, thereby further improving the quality of the molded product, the sliding of the connecting block 3 outside the fixed block 9 and the sliding of the guide column 6 in the guide hole 10 together constitute accurate guidance, ensuring the accurate alignment of the mold during the mold closing process, avoiding misalignment and deviation, thereby improving the molding precision, thereby improving the surface finish, dimensional accuracy and overall quality of the molded product, and the entire cleaning and guiding process is automatic and does not require additional manual intervention, simplifying the operation process, reducing labor intensity, improving production efficiency, and at the same time, making the daily maintenance and troubleshooting of the equipment more simple and efficient.

[0033] Working principle: when using the injection mold frame to perform front and rear ejection demolding, when the rear mold frame 2 begins to move away from the front mold frame 1, the rear mold frame 2 will gradually release the extrusion on the front ejection plate 11 and the front connecting plate 13, at this time, the plurality of springs 12 will push the front connecting plate 13 to slide inside the front mold frame 1, realizing front ejection operation, so that the front connecting plate 13 moves to the final position, at this time, the rear mold frame 2 continues to move, the rear connecting plate 14 will slide outside the fixed rod 8, when the rear mold frame 2 moves to a certain position, it will make the rear connecting plate 14 and the rear ejection plate 7 slide inside the rear mold frame 2, so that the rear ejection plate 7 pushes the molded mold to move, realizing automatic demolding effect.

[0034] Secondly, when the mold is closed, the rear mold frame 2 moves towards the front mold frame 1, causing the air cylinder 4 to gradually contract, and then causing the gas inside to be sprayed out through the connecting block 3 and the nozzle 5, realizing cleaning of the front mold frame 1 and the rear mold frame 2, at the same time, causing the connecting block 3 to slide outside the fixed block 9 at both ends of the front mold frame 1, and causing the guide column 6 to slide inside the guide hole 10, realizing guidance.

[0035] Finally, it should be noted that the above description is only a preferred embodiment of the present application and is not intended to limit the present application, although the present application has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions recorded in the foregoing embodiments or make equivalent replacements for some technical features, any modification, equivalent replacement, improvement, etc. made within the spirit and principles of the present application shall be included within the protection scope of the present application.
