DETAILED DESCRIPTION OF THE EMBODIMENTS
[0029] Referring to Figure 1As shown in the figure, the utility model provides a technical solution: an automotive armrest skeleton mold, including a bottom mold 1 and an upper mold 2. The bottom mold 1 is adapted to the upper mold 2. A mold core 3 is installed on the surface of the bottom mold 1, and a coating structure 4 is provided on the surface of the bottom mold 1. By setting the coating structure 4, it is convenient to apply the mold release agent on the surface of the mold core 3 of the bottom mold 1 and the upper mold 2, thereby preventing the injection-molded automotive armrest skeleton from adhering to the surface of the mold core 3, and then improving the production quality of the injection-molded automotive armrest skeleton. A limiting structure 5 is provided on the surface of the upper mold 2. By setting the limiting structure 5, it is convenient to connect the bottom mold 1 and the upper mold 2, thereby avoiding the cumbersome steps of using bolts and specific tools for connection when moving the mold, and facilitating the movement of the mold.
[0030] Next, specifically describe the specific settings and functions of its coating structure 4 and limiting structure 5.
[0031] Refer to Figure 2 and Figure 3 with Figure 4As shown in the figure, in this embodiment: The coating structure 4 includes a servo motor 401, which is fixedly connected to the surface of the bottom mold 1. The output end of the servo motor 401 is fixedly connected to a lead screw 402, and the lead screw 402 is rotatably connected to the surface of the bottom mold 1. A driving arm 403 is threadedly connected to the surface of the lead screw 402. One end of the driving arm 403 is fixedly connected to a frame 404, and a sponge block 405 is adhesively connected to the inner wall of the frame 404. One side of the bottom mold 1 is fixedly connected to a support arm 406. One end of the two support arms 406 is fixedly connected to an oil pot 407. A plurality of oil outlet holes 408 are opened on the lower surface of the oil pot 407. A plurality of guide rods 409 slidably penetrate through the surface of the oil pot 407. One end of the guide rod 409 is fixedly connected to a sphere 410. A plurality of spikes 411 are fixedly connected to the surface of the frame 404. After the frame 404 moves to a suitable position, it will drive the spikes 411 to squeeze the sphere 410. The sphere 410 will slide in the oil outlet hole 408 by virtue of the force of being squeezed by the spikes 411. When the sphere 410 moves, it will drive the guide rod 409 to move. When the sphere 410 moves to a suitable position, the release agent in the oil pot 407 will flow out from the oil outlet hole 408, and the release agent will drip onto the surface of the sponge block 405, thereby facilitating the addition of the release agent into the sponge block 405. A spring 412 is sleeved on the surface of the guide rod 409. The two ends of the spring 412 are respectively fixedly connected to the guide rod 409 and the oil pot 407. The guide rod 409 will move by virtue of the contracting force of the spring 412. The spring 412 serves to improve the tightness of the sphere 410 fitting in the oil outlet hole 408, thereby avoiding oil leakage from the gap between the sphere 410 and the oil outlet hole 408. A round rod 413 slidably penetrates through the surface of the driving arm 403. One end of the round rod 413 is fixedly connected to the bottom mold 1. When the driving arm 403 moves, it will slide along the surface of the round rod 413. The round rod 413 serves to limit the movement path of the driving arm 403, thereby avoiding the swing of the driving arm 403 during movement.
[0032] Referring to Figure 2 and Figure 5 As shown in the figure, specifically, the limiting structure 5 includes two brackets 51, which are respectively fixedly connected to both sides of the upper mold 2. A pin 52 slidably penetrates through the surface of the bracket 51. Limiting plates 53 are fixedly connected to both sides of the bottom mold 1. Limiting holes 54 are opened on the surface of the limiting plates 53. The size of the limiting holes 54 is adapted to the size of the pin 52. One end of each limiting plate 53 is arc-shaped, and the limiting plate 53 will gradually insert into the bracket 51. Because one end of the limiting plate 53 is arc-shaped, it is convenient to insert the limiting plate 53 into the bracket 51. One end of the pin 52 is fixedly connected to a rope 55, and the end of the rope 55 away from the pin 52 is fixedly connected to the bracket 51. When the pin 52 moves, it will pull the rope 55. The rope 55 serves to limit the position of the pin 52, thereby avoiding the loss of the pin 52 being easily pulled out of the bracket 51.
[0033] Working principle: When it is necessary to apply a release agent to the surface of the mold core 3 of the upper mold 2 on the bottom mold 1, first pour the release agent into the oil pot 407, and then drive the servo motor 401. The rotation of the servo motor 401 will drive the threaded rod to rotate. The rotation of the threaded rod will drive the driving arm 403 to move by means of the thread. The movement of the driving arm 403 will slide along the surface of the round rod 413. The round rod 413 restricts the movement path of the driving arm 403, thus preventing the driving arm 403 from swinging during movement. When the driving arm 403 moves, it will drive the frame 404 to move. The movement of the frame 404 will drive the sponge block 405 to move towards the oil pot 407. When the frame 404 moves to a suitable position, it will drive the spikes 411 to squeeze the sphere 410. The sphere 410 will slide in the oil outlet hole 408 by means of the force squeezed by the spikes 411. When the sphere 410 moves, it will drive the guide rod 409 to move. The movement of the guide rod 409 will stretch the spring 412. When the sphere 410 moves to a suitable position, the release agent in the oil pot 407 will flow out of the oil outlet hole 408, and the release agent will drip onto the surface of the sponge block 405. When the sponge block 405 is full of the release agent, drive the servo motor 401 in the opposite direction. The servo motor 401 will drive the threaded rod to reverse. The threaded rod will drive the sponge block 405 to move towards the mold core 3 by means of the driving arm 403. When the frame 404 moves away from below the oil pot 407, the guide rod 409 will move by means of the contracting force of the spring 412. The guide rod 409 will drive the sphere 410 to closely fit against the inner wall of the oil outlet hole 408, thus blocking the outlet hole. When the sponge block 405 moves to a suitable position, the sponge block 405 will slide along the surface of the mold core 3, thus applying the release agent in the sponge block 405 to the surface of the mold core 3.
[0034] When it is necessary to carry the mold, first pull the two pins 52. The pins 52 will slide in the bracket 51. When the pins 52 move, they will pull the rope 55. After the pins 52 are removed from the bracket 51, place the upper mold 2 on the bottom mold 1. When the upper mold 2 approaches the bottom mold 1, the limit plate 53 will gradually insert into the bracket 51. Since one end of the limit plate 53 is arc-shaped, it is convenient to insert the limit plate 53 into the bracket 51. After the upper mold 2 is attached to the bottom mold 1, insert the pins 52 into the bracket 51, and then press the pins 52. The pins 52 will gradually insert into the limit holes 54. When the pins 52 are completely inserted into the limit holes 54, the bottom mold 1 and the upper mold 2 are connected.

For example, it may be a fixed connection, a detachable connection, or an integral connection; it may be a mechanical connection or an electrical connection; it may be directly connected or indirectly connected through an intermediate medium, and it may be the communication inside two components. For those of ordinary skill in the art, the specific meanings of the above terms in the present utility model can be understood through specific circumstances.
