[0002] Injection molds are high-precision metal cavity tooling installed on injection molding machines. Used in conjunction with the injection molding machine, they form a mold by closing the moving and fixed molds.

[0018] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0019] Example: Figures 1-10 As shown, the present invention provides a technical solution for an automatic demolding injection mold. The automatic demolding injection mold includes a fixed mold 1 and a moving mold 2. The fixed mold 1 and the moving mold 2 are connected by an opening and closing module 3. The moving mold 2 is provided with a core-pulling module 4. The fixed mold 1 is provided with a pouring gate 5. Both the fixed mold 1 and the moving mold 2 are provided with cooling pipes, and both the fixed mold 1 and the moving mold 2 are provided with a cooling module 6. The input end of the cooling module 6 is connected to the output end of the cooling pipes, and the output end of the cooling module 6 is connected to the input end of the cooling pipes. The cooling module 6 includes a base 61, a flow distribution cavity 62, a flow supply component 63, a cooling cavity 64, a reheat cavity 65, a delivery pipe 66, a cooling port 67, and a reheat port 68; Both the fixed mold 1 and the moving mold 2 are provided with a base 61. The base 61 is provided with a flow distribution cavity 62. A flow supply component 63 is installed on the base 61. The output end of the cooling pipe is connected to the flow distribution cavity 62 through the flow supply component 63. A temperature sensor is provided at the output end of the cooling pipe. The base 61 is provided with a cooling cavity 64 and a reheating cavity 65. The tail ends of the cooling cavity 64 and the reheating cavity 65 are connected. The connection point is connected to the input end of the cooling pipe through a delivery pipe 66. The flow distribution cavity 62 is provided with a cooling port 67 and a reheating port 68 on the side near the cooling cavity 64 and the reheating cavity 65, respectively. A flow distribution regulating component 69 is provided in the flow distribution cavity 62. A flow dissipation component 7 is provided in the cooling cavity 64. A cooling plate 641 is installed in the cooling cavity 64. The cooling plate 641 is electrically connected to the temperature sensor.

[0020] When the injection mold needs to be cooled, the supply component 63 is activated to deliver the coolant carrying heat in the cooling pipe to the distribution chamber 62. The distribution chamber 62 then delivers the returning coolant to the cooling chamber 64 and the return chamber 65 respectively through the cooling port 67 and the return port 68. The coolant in the cooling chamber 64 can be cooled by the cooling plate 641 and then mixed with the naturally dissipated coolant in the return chamber 65. The cooled coolant is then delivered back to the cooling pipe through the delivery pipe 66. At the same time, the temperature sensor can monitor the temperature of the coolant in the cooling pipe and control the cooling temperature of the cooling plate 641 to be slightly lower than the coolant temperature. This allows for graded and gradual cooling of the injection molded part during the coolant circulation process, which can prevent cracking and deformation of the injection molded part.

[0021] The flow supply component 63 includes a pump 631, a return pipe 632, a delivery pipe 633, and a flow regulating valve 634; A pump 631 is mounted on the base 61. The input end of the pump 631 is connected to the output end of the cooling pipe through a return pipe 632. The output end of the pump 631 is connected to the flow distribution chamber 62 through a flow delivery pipe 633. A flow regulating valve 634 is provided on the flow delivery pipe 633. The flow regulating valve 634 is electrically connected to a temperature sensor.

[0022] When cooling the injection molded part, the pump 631 is started, and the coolant in the cooling pipe is delivered to the distribution chamber 62 through the return pipe 632 and the delivery pipe 633. The opening degree of the flow regulating valve 634 can be controlled by the temperature of the return coolant monitored by the temperature sensor. When the temperature of the coolant monitored by the temperature sensor is high, the flow regulating valve 634 can be controlled to open to the maximum extent, so as to increase the delivery flow of the delivery pipe 633.

[0023] The diversion adjustment component 69 includes a passageway 691, a sealing block 692, a fixing plate 693, a miniature electric telescopic rod 694, a linkage rod 695, and a sliding hole 696; A passageway 691 is provided between the cooling port 67 and the return port 68. Both ends of the passageway 691 are slidably installed with sealing blocks 692, and a fixing plate 693 is fixedly installed inside the passageway 691. A miniature electric telescopic rod 694 is installed on the fixing plate 693. The miniature electric telescopic rod 694 is electrically connected to the temperature sensor and is connected to one of the sealing blocks 692. The sealing blocks 692 on both sides are connected by a linkage rod 695. The fixing plate 693 has a sliding hole 696, and the linkage rod 695 passes through the sliding hole 696 and is in a sliding fit. In the initial state, the overlap between the sealing block 692 and the cooling port 67 is the largest, while the overlap between the other sealing block 692 and the heat recovery port 68 is the smallest.

[0024] When the temperature of the return coolant monitored by the temperature sensor is at its highest, the temperature sensor can control the miniature electric telescopic rod 694 to retract by a corresponding distance. This allows the miniature electric telescopic rod 694 to move the sealing block 692 at the cooling port 67 back, adjusting the overlap area between the sealing block 692 and the cooling port 67 to be minimized. At the same time, during the movement of the sealing block 692 at the cooling port 67, the linkage rod 695 can drive the sealing block 692 at the return port 68 to move outward synchronously, thereby simultaneously adjusting the overlap area between the sealing block 692 and the return port 68 to be maximized. As the temperature of the return coolant gradually decreases, the flow rate of the cooling port 67 and the return port 68 can be automatically adjusted according to the temperature of the return coolant.

[0025] The diffuser assembly 7 includes a perforation 71, a rotating column 72, a micro drive motor 73, a rotating disk 74, and a primary stirring blade 75; A perforation 71 is provided at the bottom of the cooling chamber 64. A rotating column 72 is rotatably installed in the perforation 71. A micro drive motor 73 is installed on the base 61. The output end of the micro drive motor 73 is connected to the rotating column 72. Multiple sets of rotating disks 74 are evenly installed on the part of the rotating column 72 inside the cooling chamber 64. Multiple primary stirring blades 75 are evenly installed on the side walls of the multiple sets of rotating disks 74, and flow regulating components 76 are provided on the rotating disks 74.

[0026] When the coolant enters the cooling chamber 64, the micro drive motor 73 is started, which drives the turntable 74 to rotate through the rotating column 72. During the rotation, the turntable 74 drives the primary stirring blade 75 to stir and disperse the coolant in the cooling chamber 64, which helps to improve the cooling effect of the cooling plate 641 on the coolant.

[0027] The flow regulating component 76 includes a sleeve 761, a curved channel 762, a miniature electric push rod 763, a connecting ring 764, a rotating ring 765, a drive shaft 766, and a multi-stage stirring blade 767; Each of the multiple turntables 74 is equipped with a sleeve 761. The side wall of the sleeve 761 is provided with a curved channel 762. A miniature electric push rod 763 is installed on the turntable 74. A connecting ring 764 is installed on the miniature electric push rod 763. A rotating ring 765 is rotatably installed on the connecting ring 764. A drive shaft 766 is installed on the rotating ring 765. The drive shaft 766 slides through the curved channel 762. The miniature electric push rod 763 is electrically connected to a temperature sensor. Multiple multi-stage stirring blades 767 are evenly installed on the side wall of the rotating ring 765.

[0028] When the temperature of the returning coolant is high, the temperature sensor can control the miniature electric push rod 763 to extend a corresponding distance. The miniature electric push rod 763 can drive the rotating ring 765 to move synchronously through the connecting ring 764. During the movement, the rotating ring 765 can rotate at a corresponding angle through the squeezing action of the drive shaft 766 by the curved channel 762. This allows the rotating ring 765 to drive the secondary stirring blade 767 to rotate synchronously, adjusting the angle between the secondary stirring blade 767 and the primary stirring blade 75. This helps to improve the stirring and dispersing effect of the secondary stirring blade 767 and the primary stirring blade 75 on the coolant in the cooling chamber 64, ensuring the cooling effect of the cooling plate 641 on the coolant. This achieves automatic adjustment of the angle between the secondary stirring blade 767 and the primary stirring blade 75 according to the temperature sensor.

[0029] The secondary stirring blade 767 corresponds one-to-one with the primary stirring blade 75 and is the same size. The rotating column 72 passes through the sleeve 761, the connecting ring 764 and the rotating ring 765. In the initial state, the secondary stirring blade 767 is flush with the primary stirring blade 75, and the maximum angle between the secondary stirring blade 767 and the primary stirring blade 75 is 30°.

[0030] The opening and closing module 3 includes a hydraulic cylinder 31 and a hydraulic lifting component 32. The fixed mold 1 is equipped with the hydraulic cylinder 31 and the hydraulic lifting component 32. The telescopic end of the hydraulic lifting component 32 is connected to the moving mold 2.

[0031] The core-pulling module 4 includes an inclined guide post 41, a slide rail 42, a slider 43, and a post hole 44; An inclined guide post 41 is installed on the fixed mold 1, and a slide 42 is provided in the moving mold 2. A slider 43 is slidably installed on the slide 42, and a column hole 44 is opened on the slider 43. The inclined guide post 41 is slidably inserted into the column hole 44.

[0032] When the fixed mold 1 and the moving mold 2 are closed, the moving mold 2 can use the inclined guide post 41 to squeeze the slider 43 to move along the slide 42, which can push the slider 43 inward into place, so that the slider 43 can be pressed to withstand the lateral expansion force of injection molding. When the fixed mold 1 and the moving mold 2 are opened, the inclined guide post 41 slides relative to the inclined surface of the post hole 44 on the slider 43, pushing the slider 43 on the moving mold 2 to slide laterally outward, completing the core pulling and demolding.

[0033] Working principle of the invention: When the injection mold needs to be cooled, the supply component 63 is activated to deliver the coolant carrying heat in the cooling pipe to the distribution chamber 62. The distribution chamber 62 then delivers the returning coolant to the cooling chamber 64 and the return chamber 65 respectively through the cooling port 67 and the return port 68. At the same time, the temperature sensor can monitor the temperature of the coolant in the cooling pipe and control the cooling plate 641 to be slightly lower than the coolant temperature. This enables the injection molded part to be cooled in stages during the coolant circulation process, which can prevent the injection molded part from cracking and deforming.

[0034] When the coolant temperature monitored by the temperature sensor is high, the flow regulating valve 634 can be controlled to open to the maximum extent, which facilitates increasing the delivery flow of the flow pipe 633. At the same time, the temperature sensor can control the miniature electric telescopic rod 694 to retract by a corresponding distance, so that the miniature electric telescopic rod 694 can drive the sealing block 692 at the cooling port 67 to move back, which can adjust the overlapping area between the sealing block 692 and the cooling port 67 to be minimized. At the same time, during the movement of the sealing block 692 at the cooling port 67, the linkage rod 695 can drive the sealing block 692 at the return port 68 to move outward synchronously, thereby synchronously adjusting the overlapping area between the sealing block 692 and the return port 68 to be maximized.

[0035] When the coolant enters the cooling chamber 64, the micro drive motor 73 is activated, which drives the primary stirring blade 75 via the rotating column 72 to agitate and disperse the coolant in the cooling chamber 64. At the same time, when the temperature of the returning coolant is high, the liquid flow rate in the cooling chamber 64 increases. The temperature sensor can control the micro electric push rod 763 to extend a corresponding distance. The micro electric push rod 763 can drive the rotating ring 765 to move synchronously via the connecting ring 764. During the movement, the rotating ring 765 can rotate at a corresponding angle through the squeezing action of the transmission shaft 766 by the curved channel 762, thereby allowing the rotating ring 765 to drive the secondary stirring blade 767 to rotate synchronously. Adjusting the angle between the secondary stirring blade 767 and the primary stirring blade 75 can ensure the cooling effect of the cooling plate 641 on the coolant.

[0036] It will be apparent to those skilled in the art that the present invention is not limited to the details of the exemplary embodiments described above, and that the invention can be implemented in other specific forms without departing from its spirit or essential characteristics. Therefore, the embodiments should be considered in all respects as exemplary and non-limiting, and the scope of the invention is defined by the appended claims rather than the foregoing description. Thus, all variations falling within the meaning and scope of equivalents of the claims are intended to be included within the present invention. No reference numerals in the claims should be construed as limiting the scope of the claims.
