During the demolding process, power needs to be provided separately for demolding, with a complex structure and energy waste; 3. During injection molding, it is not convenient to limit the side strip core, affecting the injection molding accuracy of the wool groove corner joint. Therefore, improvements are needed. Summary of the Invention

[0003] The purpose of the present invention is to provide a wool groove corner joint injection mold to solve the above problems and those mentioned in the background art.

[0004] To solve the above problems, the present invention provides a technical solution for a wool groove corner joint injection mold:

[0005] The wool groove corner joint injection mold includes a lower mold, an upper mold, a cooling mechanism, a demolding mechanism, a hinge frame, a mounting frame, a first side strip, a second side strip, a limiting mechanism, and an injection pipe. The upper mold is in contact with the lower mold, the cooling mechanism is arranged on the upper mold, the demolding mechanism is arranged inside the lower mold, the hinge frame is fixedly connected to the lower mold, the mounting frame is hinged inside the hinge frame, the first side strip is in contact with the lower mold, the second side strip is in contact with the lower mold, the limiting mechanism is arranged on the mounting frame, and the injection pipe is fixedly connected to the upper mold.

[0006] Preferably, the cooling mechanism includes a cold water tank, an atomizing pump, an exhaust pipe, an exchange tank, a heat conducting plate, heat dissipation holes, and a return pipe. A cold water tank is fixedly connected to the upper mold. An atomizing pump is fixedly installed on the cold water tank. The input end of the atomizing pump is fixedly connected to the cold water tank. The output end of the atomizing pump is fixedly connected to an exhaust pipe. An exchange tank is fixedly connected inside the upper mold. A plurality of uniformly distributed heat conducting plates are fixedly connected inside the exchange tank. A plurality of uniformly distributed heat dissipation holes are formed in the heat conducting plate. A return pipe is fixedly connected to the cold water tank. The return pipe is fixedly connected to both the upper mold and the exchange tank. When the atomizing pump is started, the water inside the cold water tank is atomized by the atomizing pump and discharged into the exchange tank through the exhaust pipe. The exchange tank can absorb the heat inside the upper mold and transfer it to the heat conducting plate. When the water mist contacts the heat conducting plate, the water mist can be vaporized, so as to evaporate and absorb heat for refrigeration, and the heat inside the heat conducting plate is taken out through the return pipe. When the water vapor contacts the cold water inside the cold water tank, it liquefies and releases heat, thereby effectively improving the cooling efficiency of the injection molded part and reducing the waiting time.

[0007] Preferably, the exchange tank is fixedly connected to the exhaust pipe, and the exhaust pipe is fixedly connected to the upper mold. The exhaust pipe can conduct the atomized water vapor.

[0008] Preferably, the demoulding mechanism includes a track, a slider, an inclined plane driving block, a lifting plate, a demoulding block, a steel wire rope, a guide wheel, a guide rod, and a first spring. A track is fixedly connected inside the lower mold. A slider is slidably connected to the outside of the track. An inclined plane driving block is fixedly connected to the slider. A lifting plate is slidably connected to the inclined plane driving block. A demoulding block is fixedly connected to the lifting plate. The demoulding block is slidably connected to the lower mold. The demoulding block contacts the mounting frame. A steel wire rope is fixedly connected to the inclined plane driving block. The steel wire rope is slidably connected to the lower mold. The steel wire rope is fixedly connected to the upper mold. A guide rod is fixedly connected inside the lower mold. The guide rod is slidably connected to the lifting plate. A first spring is arranged outside the guide rod. When demoulding is required, the driving device of the injection molding machine drives the upper mold to move upward. During the upward movement of the upper mold, the steel wire rope is driven to move. When the steel wire rope is straightened, the steel wire rope drives the inclined plane driving block to move. The inclined plane driving block pushes the lifting plate upward through the inclined plane and flips the mounting frame through the demoulding block. During the flipping process of the mounting frame, the injection molded strip one and strip two can be driven to flip upward, so that the injection molded part can be directly demoulded, thus avoiding the need for an additional driving mechanism for demoulding.

[0009] Preferably, a guide wheel is fixedly installed inside the lower mold. The guide wheel contacts the steel wire rope. The guide wheel can change the moving direction of the steel wire rope.

[0010] Preferably, one end of the first spring is fixedly connected to the lifting plate, and the other end of the first spring is fixedly connected to the lower mold. The first spring can drive the lifting plate to automatically reset through its elastic force.

[0011] Preferably, the limiting mechanism includes a limiting seat, a movable mounting block, a guiding column, a clamping frame, and a second spring. The limiting seat is fixedly connected to the mounting frame. The movable mounting block is slidably connected inside the limiting seat. A first side strip is clamped on the movable mounting block, and the first side strip contacts the mounting frame. The guiding column is fixedly connected inside the limiting seat. The clamping frame is slidably connected to the outer side of the guiding column. The second spring is arranged on the outer side of the guiding column. The clamping frame is clamped with the movable mounting block. First, the first side strip is installed on the movable mounting block, and then the movable mounting block is slid into the inside of the limiting seat. During the sliding process, the movable mounting block pushes the clamping frame to move along the guiding column and compresses the second spring. When the clamping frame contacts the groove on the movable mounting block, the second spring resets. The second spring drives the clamping frame to slide into the inside of the movable mounting block through its elastic force to limit the movable mounting block, so as to complete the limitation of the side strip core.

[0012] Preferably, one end of the second spring is fixedly connected to the limiting seat, and the other end of the second spring is fixedly connected to the clamping frame. The second spring can drive the clamping frame to automatically reset through its elastic force.

[0013] The beneficial effects of the present invention are as follows: The present invention relates to a groove-connected corner injection mold, which has the characteristics of being able to quickly cool the injection molded part, facilitating the limitation of the side strip core, and facilitating demolding. In specific use, compared with the traditional groove-connected corner injection mold, the present groove-connected corner injection mold has the following beneficial effects:

[0014] First of all, by adding structures such as a cold water tank, an atomizing pump, and an exchange tank to the upper mold, the atomized cold water can be discharged into the inside of the exchange tank by the atomizing pump to exchange heat with the heat conducting plate and vaporize. When vaporizing, the heat inside the heat conducting plate is sucked out, and then the water vapor is discharged into the inside of the cold water tank through the return pipe, so as to transfer the heat inside the mold and effectively increase the heat dissipation efficiency of the mold.

[0015] Secondly, by adding structures such as steel wires, demolding blocks, and inclined plane driving blocks to the inside of the lower mold, the inclined plane driving block can be moved by the steel wire during the mold opening process. During the moving process of the inclined plane driving block, the demolding block can be driven by the lifting plate to push the mounting frame, so as to complete the demolding of the injection molded part. And the side strip core can be limited by the limiting mechanism on the mounting frame, which can effectively prevent the core from shifting during the injection process and increase the injection accuracy.

[0024] As Figure 1-6 shown, the following technical solutions are adopted in this specific implementation manner:

[0025] Example:

[0026] The groove-connected corner injection mold includes a lower mold 1, an upper mold 2, a cooling mechanism 3, a demolding mechanism 4, a hinge frame 5, a mounting bracket 6, a side bar one 7, a side bar two 8, a limiting mechanism 9, and an injection pipe 10.

The side bar two 8 is in contact with the lower mold 1. The limiting mechanism 9 is arranged on the mounting bracket 6. The injection pipe 10 is fixedly connected to the upper mold 2.

[0027] Among them, the cooling mechanism 3 includes a cold water tank 31, an atomization pump 32, an exhaust pipe 33, an exchange tank 34, a heat conduction plate 35, heat dissipation holes 36, and a return pipe 37. A cold water tank 31 is fixedly connected to the upper mold 2. An atomization pump 32 is fixedly installed on the cold water tank 31. The input end of the atomization pump 32 is fixedly connected to the cold water tank 31. The output end of the atomization pump 32 is fixedly connected to an exhaust pipe 33. An exchange tank 34 is fixedly connected to the inside of the upper mold 2. A plurality of uniformly distributed heat conduction plates 35 are fixedly connected to the inside of the exchange tank 34. A plurality of uniformly distributed heat dissipation holes 36 are formed in the heat conduction plate 35. A return pipe 37 is fixedly connected to the cold water tank 31. The return pipe 37 is fixedly connected to both the upper mold 2 and the exchange tank 34. When the atomization pump 32 is started, the atomization pump 32 atomizes the water inside the cold water tank 31 and discharges it into the inside of the exchange tank 34 through the exhaust pipe 33. The exchange tank 34 can absorb the heat inside the upper mold 2 and transfer it to the heat conduction plate 35. When the water mist contacts the heat conduction plate 35, the water mist can be vaporized, so that evaporation can absorb heat and refrigerate. The heat inside the heat conduction plate 35 is taken out through the return pipe 37. When the water vapor contacts the cold water inside the cold water tank 31, it liquefies and releases heat, so that the cooling efficiency of the injection molded part can be effectively improved and the waiting time can be reduced.

[0028] Among them, the exchange tank 34 is fixedly connected to the exhaust pipe 33, and the exhaust pipe 33 is fixedly connected to the upper mold 2. The exhaust pipe 33 can conduct the atomized water vapor.

[0029] Among them, the demolding mechanism 4 includes a track 41, a slider 42, an inclined surface drive block 43, a lifting plate 44, a demolding block 45, a steel wire rope 46, a guide wheel 47, a guide rod 48, and a first spring 49. The track 41 is fixedly connected inside the lower mold 1. The slider 42 is slidably connected to the outside of the track 41. The inclined surface drive block 43 is fixedly connected to the slider 42. The lifting plate 44 is slidably connected to the inclined surface drive block 43. The demolding block 45 is fixedly connected to the lifting plate 44. The demolding block 45 is slidably connected to the lower mold 1. The demolding block 45 contacts the mounting frame 6. The steel wire rope 46 is fixedly connected to the inclined surface drive block 43. The steel wire rope 46 is slidably connected to the lower mold 1. The steel wire rope 46 is fixedly connected to the upper mold 2. The guide rod 48 is fixedly connected inside the lower mold 1. The guide rod 48 is slidably connected to the lifting plate 44. The first spring 49 is arranged outside the guide rod 48. When demolding is required, the driving device of the injection molding machine drives the upper mold 2 to move upward. During the upward movement of the upper mold 2, the steel wire rope 46 is driven to move. When the steel wire rope 46 is straightened, the steel wire rope 46 drives the inclined surface drive block 43 to move. The inclined surface drive block 43 pushes the lifting plate 44 to move upward through the inclined surface, and the mounting frame 6 is flipped through the demolding block 45. During the flipping process of the mounting frame 6, the injection-molded strip one 7 and strip two 8 can be driven to flip upward, so that the injection-molded part can be directly demolded, thereby avoiding the need for an additional driving mechanism for demolding.

[0030] Among them, the guide wheel 47 is fixedly installed inside the lower mold 1. The guide wheel 47 contacts the steel wire rope 46, and the guide wheel 47 can change the moving direction of the steel wire rope 46.

[0031] Among them, one end of the first spring 49 is fixedly connected to the lifting plate 44, and the other end of the first spring 49 is fixedly connected to the lower mold 1. The first spring 49 can drive the lifting plate 44 to automatically reset through the elastic force.

[0032] Among them, the limiting mechanism 9 includes a limiting seat 91, a movable mounting block 92, a guide post 93, a clamping frame 94, and a second spring 95. The limiting seat 91 is fixedly connected to the mounting frame 6. The movable mounting block 92 is slidably connected inside the limiting seat 91. The first side strip 7 is clamped on the movable mounting block 92. The first side strip 7 contacts the mounting frame 6. The guide post 93 is fixedly connected inside the limiting seat 91. The clamping frame 94 is slidably connected to the outer side of the guide post 93. The second spring 95 is arranged on the outer side of the guide post 93. The clamping frame 94 is clamped with the movable mounting block 92. First, the first side strip 7 is installed on the movable mounting block 92, and then the movable mounting block 92 is slid into the limiting seat 91. During the sliding process, the movable mounting block 92 pushes the clamping frame 94 to move along the guide post 93 and compresses the second spring 95. When the clamping frame 94 contacts the groove on the movable mounting block 92, the second spring 95 resets. The second spring 95 drives the clamping frame 94 to slide into the movable mounting block 92 by its elastic force to limit the movable mounting block 92, so as to complete the limiting of the side strip core.

[0033] Among them, one end of the second spring 95 is fixedly connected to the limiting seat 91, and the other end of the second spring 95 is fixedly connected to the clamping frame 94. The second spring 95 can drive the clamping frame 94 to automatically reset by its elastic force.

[0034] The use state of the present invention is as follows: when it is necessary to inject plastic into the first side strip 7 and the second side strip 8, first install the first side strip 7 on the movable mounting block 92, and then slide the movable mounting block 92 into the limiting seat 91. During the sliding process, the movable mounting block 92 pushes the clamping frame 94 to move along the guide post 93 and compresses the second spring 95. When the clamping frame 94 contacts the groove on the movable mounting block 92, the second spring 95 resets. The second spring 95 drives the clamping frame 94 to slide into the movable mounting block 92 by its elastic force to limit the movable mounting block 92, so as to complete the limiting of the side strip core;

[0035] After the installation is completed, the upper mold 2 and the lower mold 1 are closed. After the closing is completed, the inside of the mold cavity is injected through the injection pipe 10. After the injection is completed, the atomization pump 32 is started. The atomization pump 32 atomizes the water in the cold water tank 31 and discharges it into the inside of the exchange tank 34 through the exhaust pipe 33. The exchange tank 34 can absorb the heat inside the upper mold 2 and transfer it to the heat conducting plate 35. When the water mist contacts the heat conducting plate 35, the water mist can be vaporized when contacting, so as to evaporate and absorb heat for refrigeration. The heat inside the heat conducting plate 35 is taken out through the return pipe 37. When the water vapor contacts the cold water in the cold water tank 31, it liquefies and releases heat, so as to effectively improve the cooling efficiency of the injection molded part and reduce the waiting time;

[0036] After cooling, when demolding is required, the driving device of the injection molding machine drives the upper mold 2 to move upward. During the upward movement of the upper mold 2, the wire rope 46 is driven to move. When the wire rope 46 is straightened, the wire rope 46 drives the inclined plane driving block 43 to move. The inclined plane driving block 43 pushes the lifting plate 44 upward through the inclined plane and flips the mounting bracket 6 through the demolding block 45. During the flipping process of the mounting bracket 6, the injection-molded side strip one 7 and side strip two 8 can be driven to flip upward, enabling the injection-molded part to be directly demolded, thus avoiding the need for an additional driving mechanism for demolding.
