[0027] See also Figure 1-5 , the utility model provides a technical solution:

[0028] A leakage-proof plastic toy injection mold, comprising:

[0029] A bracket 1, the upper end of the bracket 1 is fixedly connected with a lower mold 2, guide pillars 3 are respectively fixed on both sides of the upper surface of the lower mold 2, the outer wall of the guide pillars 3 is sleeved with an upper mold 4, the lower mold 2 and the upper mold 4 are fitted together, and the upper mold 4 and the guide pillars 3 are slidably arranged, so that the upper mold 4 moves along the guide pillars 3 and fits the lower mold 2, thereby stably closing the mold;

[0030] A double-headed servo motor 5 is fixedly arranged on the upper surface of the bracket 1. Transmission rods 6 are respectively fixed at both ends of the output shaft of the double-headed servo motor 5. A sleeve 7 is sleeved on the outer wall of the transmission rod 6. A support rod 8 is movably connected to the upper surface of the sleeve 7. A thimble 9 is movably installed on the upper end of the support rod 8. The transmission rod 6 and the bracket 1 are rotatably connected, so that the double-headed servo motor 5 can drive the transmission rod 6 to rotate;

[0031] The collecting box 10 is slidably mounted on the outer wall of the lower mold 2, and the two sides of the lower surface of the collecting box 10 are respectively fixed with a clamping sleeve 11, the outer wall of the lower mold 2 below the clamping sleeve 11 is fixedly connected with a clamping member 12, and the outer wall of the lower end side of the clamping member 12 is fixedly mounted with a supporting plate 13, and the inner wall of the end of the supporting plate 13 is installed with a limiting mechanism 14.

[0032] In one embodiment, the transmission rod 6 and the sleeve 7 are threadedly connected, and the direction of the thread arranged on the outer wall of the transmission rod 6 is symmetrically distributed about the longitudinal center axis of the double-headed servo motor 5, so that the sleeve 7 can move toward or oppositely along the transmission rod 6 at the same time as the transmission rod 6 rotates.

[0033] In one embodiment, the two ends of the support rod 8 respectively form a rotating structure with the sleeve 7 and the ejector pin 9, and the ejector pin 9 and the lower mold 2 form a sliding structure, so that as the sleeve 7 moves, the sleeve 7 drives the support rod 8 to move, so that the support rod 8 drives the ejector pin 9 to slide relative to the lower mold 2, thereby ejecting the plastic toy in the lower mold 2.

[0034] In one embodiment, the ferrule 11 and the clamping member 12 are slidably arranged, so that when the collecting box 10 is vertically moved for disassembly, the collecting box 10 drives the ferrule 11 to slide relative to the clamping member 12 .

[0035] In one of the preferred embodiments, the limiting mechanism 14 includes a limiting arm 1401 and a clamping rod 1402, and the limiting arm 1401 is movably installed on the inner wall of the end of the support plate 13, and the upper inner wall of the limiting arm 1401 is movably provided with a clamping rod 1402, which is convenient for limiting the clamping sleeve 11 through the limiting mechanism 14, so that the collection box 10 can be stably installed on the outside of the lower mold 2.

[0036] In one of the preferred embodiments, the limiting arm 1401 and the support plate 13 are rotatably arranged, the card rod 1402 is slidably connected to the limiting arm 1401 and the card sleeve 11 respectively, and the card rod 1402 is connected to the limiting arm 1401 through a spring, and the card rod 1402 and the card member 12 are fitted together, so that the user can pull the card rod 1402 to move the card rod 1402 relative to the limiting arm 1401, thereby allowing the card rod 1402 to detach from the limiting arm 1401, and then through the rotation of the limiting arm 1401, the card rod 1402 and the card sleeve 11 are misaligned, thereby facilitating the user to move the collection box 10, and at the same time, the card rod 1402 is elastically supported by the spring.

[0037] The working principle of the utility model is as follows: when using the plastic toy injection mold to prevent leakage of materials, first Figure 1-4 As shown, the user injects the plastic raw material into the lower mold 2, and then the user sets the upper mold 4 to the outside of the guide column 3, and then the user moves the upper mold 4 downward to fit the lower mold 2. At this time, the raw material is molded in the cavity formed by the lower mold 2 and the upper mold 4, and the overflowing raw material flows into the collecting box 10, so as to prevent the mold from leaking. When the plastic toy is formed, the user starts the double-headed servo motor 5, and then the double-headed servo motor 5 drives the transmission rod 6 to rotate, and then the sleeve 7 moves in the opposite direction along the transmission rod 6 at the same time, and then the sleeve 7 rotates relative to the lower end of the support rod 8 and drives the lower end of the support rod 8 to move, and at the same time, the upper end of the support rod 8 rotates relative to the ejector pin 9 and drives the ejector pin 9 to move relative to the lower mold 2, and then the ejector pin 9 moves upward to eject the plastic toy in the lower mold 2, and the toy is demolded, as shown in FIG. Figure 1-2 and Figure 4-5As shown, the user then removes the collection box 10. At this time, the user pulls the card rod 1402 to move relative to the limit arm 1401, and the card rod 1402 compresses the spring to deform. Then the user rotates the limit arm 1401 to drive the card rod 1402 and the card sleeve 11 to be misaligned. Next, the user releases the card rod 1402 and operates the remaining card rod 1402. Then the user moves the collection box 10 up to disengage from the lower mold 2, and as the collection box 10 moves, the collection box 10 drives the card sleeve 11 to disengage from the clamp 12, so that the device can easily disassemble the collection box 10, and then it is convenient for the user to take out the raw materials in the collection box 10, thereby improving the practicality of the device.
