[0055] Please combine Figures 1 to 15As shown, the present invention provides an injection mold device for automobile injection molded parts, the device has two injection molds 10 slidably mounted on a mounting frame 70, and the two injection molds 10 can move relative to each other or move away from each other. When the two injection molds 10 are combined, an injection cavity 101 is formed inside the two. An injection hole is opened on the injection mold 10, and the injection hole is connected to the injection cavity 101. After the two injection molds 10 are combined, the injection liquid is input into the injection cavity 101 through the injection hole. The method of adding the injection liquid to the injection cavity 101 is a mature prior art in the art, so it is not described here. The inner surfaces of the two injection molds 10 are both provided with a receiving cavity 102;

[0056] A support frame assembly is slidably mounted on a rotating column 32. A plurality of support frame assemblies are evenly spaced in the circumferential direction of the rotating column 32. The support frame assembly is composed of two edge frames 30 that are arranged opposite to each other. The shape of the edge frame 30 matches the accommodating cavity 102. When the two injection molds 10 are combined, the two edge frames 30 are respectively located in the accommodating cavities 102 opened on the two injection molds 10, and edge grooves 301 are opened on the opposite surfaces of the two edge frames 30. When the two edge frames 30 are combined, the two edge grooves 301 form the edge portion of the injection cavity 101.

[0057] An intermittent rotating mechanism, one end of which is fixedly mounted on one end of the rotating column 32, and the other end of which is slidably mounted on one of the injection molds 10; the intermittent rotating mechanism is configured to rotate the rotating column 32 at a fixed angle when the two injection molds 10 move away from each other;

[0058] The column rod 80 is rotatably mounted on the two injection molds 10, and the third gear 84 is fixedly mounted on the two column rods 80. The electric telescopic rod 83 is fixedly mounted on the two injection molds 10, and the third tooth plate 85 is fixedly mounted on the movable end of the electric telescopic rod 83. The third tooth plate 85 keeps meshing with the third gear 84. The inclined portion 81 is fixedly mounted on the opposite ends of the two column rods 80, and a connector 82 is fixedly arranged on one end of the inclined portion 81. An inclined groove 302 adapted to the inclined portion 81 is provided on the edge frame 30, and a straight groove 303 adapted to the connector 82 is also provided on the edge frame 30. When the two injection molds 10 move relative to each other for mold closing, the two connectors 82 will be inserted into the straight groove 303, and the inclined portion 81 will be inserted into the inclined groove In the groove 302, the inclined portion 81 fits with the inclined groove 302 to calibrate the position of the edge frame 30 and the injection mold 10 to prevent the position deviation between the two. A limiting head 821 is fixedly installed on one of the connecting heads 82, and a limiting groove 822 adapted to the limiting head 821 is opened on the other connecting head 82. After the two connecting heads 82 are combined, the limiting head 821 will be inserted into the limiting groove 822. During the combination of the limiting head 821 and the limiting groove 822, the positions of the two injection molds 10 can be calibrated. Therefore, the two injection molds 10 and the edge frame 30 can be accurately combined, and it is not easy to be misplaced, which avoids the shape of the injection cavity 101 changing due to the position deviation after the mold is closed, which affects the molding shape of the injection molded part;

[0059] An air supply assembly, one end of which is fixedly mounted on the mounting frame 70, and the other end of which is fixedly connected to the ends of the two pillars 80 which are far away from each other. When the two injection molds 10 are combined, the air supply assembly supplies air to the pillars 80;

[0060] Among them, a frame 93 is fixedly installed on the outer surface of the two injection molds 10. The two frames 93 are combined to form a closed cavity. Rubber pads can be fixedly installed on the edges of the two frames 93 to improve the sealing of the cavity. An air pressure detector 94 is fixedly installed on the frame 93; a through hole 823 is opened on the two connecting heads 82, and a channel is provided inside the column 80. After the two injection molds 10 are combined, the air supply component transports the gas to the inside of the column 80, and the gas can be discharged through the through hole 823, so that the gas enters the gap between the two injection molds 10 and the two edge frames 30 after they are combined. At this time, the air pressure detector 94 monitors the air pressure changes inside the cavity in real time. If there is no change in the air pressure, the injection mold 10 and the edge frame 30 are completed. If the air pressure gradually increases , the injection mold 10 and the edge frame 30 fail to complete the mold closing, and the two connecting heads 82 are provided with through grooves 824, and the connecting heads 82 are also provided with locking grooves 825. The edge frame 30 is fixedly installed with a locking block 304 at the straight groove 303; a rotating member is provided between the column rod 80 and the injection mold 10. After the injection mold 10 and the edge frame 30 complete the mold closing, the rotating member drives the column rod 80 to rotate, so that the locking block 304 enters the locking groove 825 from the through groove 824, and the two injection molds 10 and the edge frame 30 are locked, so that the two injection molds 10 and the edge frame 30 remain in the mold closing state, and the injection liquid can be injected into the injection cavity 101; under the effect of the above structure, the shape of the processed injection molded part can be extremely uniform, without small deviations, thereby improving the injection molding quality;

[0061] With respect to the above structure, after the two injection molds 10 are merged, the two edge frames 30 located inside the two injection molds 10 are also merged together, so that a complete injection cavity 101 is formed inside the two injection molds 10. After the injection liquid is injected into the injection cavity 101 and formed, the two injection molds 10 can be moved back to back. Since the edge of the molded injection molded part is located between the two edge frames 30, the injection molded part is supported on the two edge frames 30. After the two injection molds 10 move back to back, the intermittent rotating mechanism rotates the rotating column 32 by a certain angle. At this time, the position of the support frame assembly located in the circumferential direction of the rotating column 32 is completed. Switch, a support frame assembly that does not support the injection molded parts moves between the two injection molds 10, and the support frame assembly can cooperate with the two injection molds 10 to form an injection cavity 101, and the other support frame assemblies expose the injection molded parts they support to the air. In this process, the molded injection molded parts do not need to be manually removed by the staff, which reduces the difficulty of the staff's work and does not require the injection molded parts to be cooled to a lower temperature before continuing the injection molding. The present invention utilizes multiple support frame assemblies to expose the injection molded parts to the air for continued cooling, while the two injection molds 10 can continue to perform injection molding, which improves the processing efficiency of the injection molded parts, is more practical, and also improves the safety of the injection molding process.

[0062] As for the rotating part, the rotating part includes an electric telescopic rod 83, a third gear 84 and a third tooth plate 85. The fixed end of the electric telescopic rod 83 is fixedly mounted on the injection mold 10, and the third tooth plate 85 is fixedly mounted on the output end of the electric telescopic rod 83. The third gear 84 is fixedly mounted on the outer surface of the column 80, and the third gear 84 and the third tooth plate 85 remain in a meshing state.

[0063] As for the air supply assembly, the air supply assembly includes an air pump 90, two telescopic tubes 91 and two hard tubes 92; the air pump 90 is fixedly installed on the support plate 71, one end of the two telescopic tubes 91 is fixedly connected to the output end of the air pump 90, one end of the two hard tubes 92 is fixedly connected to the other end of the two telescopic tubes 91, and the other ends of the two hard tubes 92 are fixedly connected to the two column rods 80.

[0064] Based on the first embodiment, the solution in the first embodiment is further detailed in combination with the following specific working method, as described below: Embodiment 2

[0065] Now let's describe the intermittent rotating components. Figures 5 to 12 As shown, the intermittent rotation mechanism includes a first tooth plate 50, a first gear 40, a driving bevel gear 41, a driven bevel gear 42, an actuator assembly and a guide;

[0066] Among them, a first slider 501 is fixedly installed on the first toothed plate 50, a first slide groove 103 for the first slider 501 to slide is opened on one of the injection molds 10, the first gear 40 is rotatably installed on the mounting frame 70, the active bevel gear 41 is fixedly connected to the first gear 40, and the driven bevel gear 42 is rotatably installed on the mounting frame 70, and the driven bevel gear 42 is kept in meshing state with the active bevel gear 41; one end of the actuator is fixedly connected to the rotating column 32, and the other end is fixedly connected to the driven bevel gear 42. When the two injection molds 10 move in opposite directions, the first toothed plate 50 will move with it. The connected injection molds 10 move together, the first toothed plate 50 can mesh with the first gear 40 and rotate the first gear 40, and under the transmission action of the active bevel gear 41 and the driven bevel gear 42, the actuator drives the rotating column 32 to rotate a certain angle; the guide is fixedly installed on the mounting frame 70, and the guide is slidably connected to the first toothed plate 50. The guide is configured to keep the first toothed plate 50 and the first gear 40 in meshing state when the two injection molds 10 move away from each other; when the two injection molds 10 move relative to each other, the first toothed plate 50 and the first gear 40 are kept separated.

[0067] In view of the above structure, the specific structures of the execution components and the guide components are introduced;

[0068] As for the execution component, the execution component includes a disc 43, a fixed rod 45 and a rotating block 44; a fixed disc 46 is fixedly installed on one end of the rotating column 32, and the rotating block 44 is fixedly installed on the surface of the fixed disc 46. Second arc-shaped notches 441 are evenly spaced in the circumferential direction of the rotating block 44, and the number of the second arc-shaped notches 441 is set to be the same as the number of the supporting frame components. A pushing groove 442 is set between two adjacent second arc-shaped notches 441. The disc 43 is fixed on one end of the driven bevel gear 42, and the edge curvature of the disc 43 is the same as the curvature of the second arc-shaped notch 441. The edge of the disc 43 fits on the second arc-shaped notch 441, which can prevent the rotating column 32 from rotating by itself. A first arc-shaped notch 431 is opened on the disc 43. When the first arc-shaped notch 431 moves to the second arc-shaped notch 441, the rotating block 44 can The fixed rod 45 is fixedly mounted on the disc 43, and a push rod 451 is fixedly arranged on the fixed rod 45. The push rod 451 is located at the first arc-shaped notch 431. When the disc 43 rotates, the push rod 451 enters the push groove 442 to drive the rotating block 44 to rotate, and drives the rotating column 32 to rotate a fixed angle. As for the advantages of the actuator, most of the injection molded parts on the car are not flat plate-like structures. When the two injection molds 10 move in opposite directions, they need to move a certain distance to be completely separated from the injection molded parts. The actuator in the present invention can avoid this problem. The disc 43 needs to be rotated by a certain angle first to enable the push rod 451 to enter the push groove 442 to drive the rotating block 44 to rotate. During the period when the push rod 451 enters the push groove 442, the two injection molds 10 can be completely separated from the injection molded parts.

[0069] As for the guide member, the guide member is a guide plate 53, which is fixedly mounted on the mounting frame 70, and a track rod 502 is fixedly mounted on the first tooth plate 50, and a first track 531, a vertical track 532 and a second track 533 for the track rod 502 to slide are provided on the guide plate 53, the top end of the vertical track 532 is connected to one end of the first track 531, the bottom end of the vertical track 532 is connected to one end of the second track 533, the other end of the first track 531 is connected to the other end of the second track 533, and a rotating plate 52 is rotatably mounted at the other end of the second track 533, and a torsion spring 521 is fixedly arranged between the rotating plate 52 and the guide plate 53, and when the two injection molds 10 move away from each other until they stop moving, the track rod 502 slides in the first track 531 until it moves to the first track 531. The track rod 502 is at the end position of the track 531. At this time, the track rod 502 enters the top position of the vertical track 532. Under the action of the gravity of the first tooth plate 50, the track rod 502 falls to the bottom end of the vertical track 532. The first tooth plate 50 and the first gear 40 are staggered in the height direction. When the two injection molds 10 move relative to each other until the merger is completed, the track rod 502 slides in the second track 533, so that the first tooth plate 50 and the first gear 40 remain separated. When the track rod 502 moves to the end position of the second track 533, the track rod 502 will pass over the rotating plate 52 and enter the upper surface of the rotating plate 52. At this time, the first tooth plate 50 and the first gear 40 are at the same height again. When the two injection molds 10 move away from each other, the first tooth plate 50 can drive the first gear 40 to rotate.

[0070] With regard to the above structure, it should be noted that a limiting plate 51 is fixedly installed on the first tooth plate 50, and the limiting plate 51 has a blocking plate 511 and a movable cavity 512.
