Technical Field

[0001] The utility model relates to the technical field of injection molds, and specifically relates to an injection mold with an injection hole cleaning structure. Background Technique

[0002] An injection mold is a tool for producing plastic products; it is also a tool for giving plastic products a complete structure and precise dimensions. Injection molding is a processing method used when mass-producing some complex-shaped parts. Specifically, it means injecting the heat-melted plastic into the mold cavity under high pressure by an injection molding machine, and after cooling and solidifying, the formed product is obtained.

[0003] After the injection molding of the injection mold, the finished products are left in the injection hole cavity of the lower mold, and the finished products need to be taken out. However, when taking out, due to the existence of excess scraps at the edges, the scraps are likely to fall into the injection hole cavity when taken out. Therefore, to ensure product quality, manual cleaning is required, but the manual cleaning method is relatively slow and prone to residual problems. Content of the Utility Model

[0004] Aiming at the deficiencies of the prior art, the utility model provides an injection mold with an injection hole cleaning structure, which solves the problem that the scraps are likely to fall into the injection hole cavity when taken out. Therefore, to ensure product quality, manual cleaning is required, but the manual cleaning method is relatively slow and prone to residual problems.

[0005] To achieve the above objectives, the utility model is realized through the following technical solutions: an injection mold with an injection hole cleaning structure, including an upper mold and a lower mold, and a cleaning device is arranged on the surface of the lower mold.

A sleeve plate and a second air cylinder are respectively rotatably sleeved in the inner cavities of the two rotating parts. One end of the second air cylinder is rotatably connected to the side surface of the sleeve plate. A connecting plate is slidably sleeved in the inner cavity of the sleeve plate. First air cylinders are symmetrically arranged at the bottom of the connecting plate. One end of each first air cylinder is provided with a fixing plate, and nozzles are symmetrically communicated with the surface of the fixing plate. A connecting plate is fixedly connected to the surface of the fixing plate, and the connecting plate is communicated with the nozzles. An air pipe is fixedly communicated with the top of the connecting plate, and the air pump is communicated with the air pipe.

[0012] Advantageous Effects

[0013] The present utility model provides an injection mold with an injection hole cleaning structure. Compared with the prior art, it has the following advantageous effects:

[0014] 1. For the injection mold with an injection hole cleaning structure, the output end of the driving motor drives the lead screw to rotate in the inner cavity of the driving seat, drives the sliding block to move to one side, and drives the brush to move on the top of the lower mold for cleaning. As it moves, the brush enters the injection cavity on the top of the lower mold and also starts cleaning. While cleaning, the air pump is started. Through the connection of the air pipe, the gas enters the connecting plate, then enters the spray head, and while the brush is cleaning, it is blown through the spray head at the same time, so as to better clean the impurities remaining in the injection hole cavity.

[0015] 2. For the injection mold with an injection hole cleaning structure, by rotating the bolt rod on the surface of the sleeve plate, the connecting plate slides in the inner cavity of the sleeve plate to adjust the height of the connecting plate, so that it can be applied to molds with limit rods of different heights.

[0016] 3. For the injection mold with an injection hole cleaning structure, through the rotational connection of the sleeve plate and the second cylinder on the rotating member, the telescopic rotation of the second cylinder drives the sleeve plate to rotate, so that the sleeve plate and the connecting plate are located outside one side of the lower mold, and it is not easy to affect the injection of the upper mold and the lower mold.

[0022] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative work shall fall within the protection scope of the present invention.

[0023] Please refer to Figure 1 , the present invention provides a technical solution: an injection mold with an injection hole cleaning structure, including an upper mold 1 and a lower mold 2. A cleaning device 3 is arranged on the surface of the lower mold 2. When the upper mold 1 and the lower mold 2 are injection-molded and fitted, the cleaning device 3 will incline outward at the edge of the lower mold 2 and will not affect the injection molding of the upper mold 1 and the lower mold 2.

[0024] Please refer to Figures 2 - 4 , the cleaning device 3 includes a driving seat 31 and an air pump 37. The driving seat 31 is fixedly connected to the surface of the lower mold 2, and the air pump 37 is fixedly installed on the side of the lower mold 2. A lead screw 32 is rotatably sleeved in the inner cavity of the driving seat 31, and one end of the driving seat 31 is fixedly connected to a driving motor 33. The output end of the driving motor 33 is fixedly connected to one end of the lead screw 32. Among them, the driving motor 33 has a function of reverse rotation and can be controlled through an externally connected control panel.

[0025] A sliding block 311 is threadedly sleeved on the surface of the lead screw 32. The sliding block 311 fits with the inner cavity of the driving seat 31, so that the sliding block 311 slides along the inner cavity of the driving seat 31. Two rotating parts 39 are fixedly arranged on the surface of the sliding block 311. A sleeve plate 38 and a second cylinder 310 are respectively rotatably sleeved in the inner cavities of the two rotating parts 39. One end of the second cylinder 310 is rotatably connected to the side of the sleeve plate 38, and a connecting plate 34 is slidably sleeved in the inner cavity of the sleeve plate 38. A bolt rod is arranged on the surface of the sleeve plate 38. By rotating the bolt rod, the height of the connecting plate 34 in the inner cavity of the sleeve plate 38 can be adjusted.

[0026] A first cylinder 35 is symmetrically arranged at the bottom of the connecting plate 34. One end of the first cylinder 35 is provided with a fixing plate 312, and spray nozzles 316 are symmetrically communicated with the surface of the fixing plate 312. A connecting plate 313 is fixedly connected to the surface of the fixing plate 312, and the connecting plate 313 is communicated with the spray nozzles 316. An air pipe 36 is fixedly communicated with the top of the connecting plate 313, and an air pump 37 is communicated with the air pipe 36. A brush 315 is arranged at the bottom of the fixing plate 312. The length of the brush 315 is greater than that of the rubber roller 314. Therefore, when the rubber roller 314 abuts against the top of the lower mold 2, the brush 315 will also be squeezed into contact with the top of the lower mold 2. Rubber rollers 314 are fixedly connected to both sides of the bottom of the fixing plate 312.

[0027] During use, after the upper mold 1 and the lower mold 2 complete injection molding and the finished products are taken out, it is necessary to clean the injection hole cavity in the lower mold 2. Since there are limit rods on the surface of the lower mold 2 that contact the upper mold 1, the bolt rod on the surface of the rotating sleeve plate 38 is rotated, so that the connecting plate 34 slides in the inner cavity of the sleeve plate 38 to adjust the height of the connecting plate 34, making the height of the connecting plate 34 greater than the limit rod on the surface of the lower mold 2. Then, the second cylinder 310 is started. Since the second cylinder 310 is rotatably connected to both the rotating member 39 and the sleeve plate 38, when the second cylinder 310 retracts, it will drive the sleeve plate 38 to rotate in the inner cavity of the rotating member 39 and change the angle of the second cylinder 310 itself, so that the sleeve plate 38 is vertical.

[0028] Then, the first cylinder 35 is started, so that one end of the first cylinder 35 drives the fixing plate 312 to descend until the rubber roller 314 abuts against the top of the lower mold 2 and stops. Then, the drive motor 33 is started, so that the output end of the drive motor 33 drives the lead screw 32 to rotate in the inner cavity of the drive seat 31, drives the sliding block 311 to move to one side, and drives the brush 315 to move on the top of the lower mold 2 for cleaning. As it moves, the brush 315 enters the injection cavity on the top of the lower mold 2 and also starts to clean. While cleaning, the air pump 37 is started. Through the connection of the air pipe 36, gas enters the connecting plate 313, then enters the spray nozzles 316, and while the brush 315 is cleaning, it is blown through the spray nozzles 316, so as to better clean the impurities remaining in the injection hole cavity. After cleaning, the drive motor 33 can be reversed to reset the sliding block 311, then the first cylinder 35 drives the fixing plate 312 to move upward, and finally the second cylinder 310 is telescoped to drive the sleeve plate 38 to rotate, so that the sleeve plate 38 and the connecting plate 34 change from a vertical state to an inclined state, so that they can leave the top of the lower mold 2 without affecting the injection molding of the upper mold 1 and the lower mold 2.
