Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0021] Please see Figure 1-4 A processing mold for injection molding millimeter-wave radar housing includes a support base 1, a lower mold 2 in contact with the upper end of the support base 1, an upper mold 3 in contact with the upper end of the lower mold 2, a slider 4 slidably connected inside the lower mold 2, a locking block 41 fixedly connected to the upper end of the slider 4, a locking groove 42 opened inside the upper mold 3, the locking block 41 in contact with the lower mold 2, and the locking block 41 and the locking groove 42 slidably connected. Through the design of the locking groove 42 and the locking block 41, the upper mold 3 can be easily disassembled. A threaded rod 43 is rotatably connected inside the lower mold 2.

[0022] Please see Figure 2-4 The threaded rod 43 has positive and negative threads on its outer side. The threaded rod 43 is connected to the slider 4 by threads. A retaining ring 44 is fixedly connected to the outer side of the threaded rod 43. The retaining ring 44 contacts the inner wall of the lower mold 2. The retaining ring 44 can limit the threaded rod 43. A knob 45 is fixedly connected to the end of the threaded rod 43 away from the lower mold 2. The knob 45 contacts the lower mold 2. The knob 45 can easily rotate the threaded rod 43. A defoaming mechanism 5 is provided on the lower mold 2.

[0023] Please see Figure 2-4The defoaming mechanism 5 includes a connecting block 51. The lower end of the lower mold 2 is fixedly connected to the connecting block 51, which is slidably connected to the support base 1. The right side of the connecting block 51 is fixedly connected to the connecting rod 52, which is slidably connected to the support base 1. The inside of the support base 1 is fixedly connected to the fixing plate 53, which is slidably connected to the connecting rod 52. The fixing plate 53 is designed to limit the movement of the connecting rod 52. The inside of the support base 1 is provided with a spring 54. One end of the spring 54 contacts the connecting rod 52, and the other end of the spring 54 contacts the support base 1. The spring 54 is designed to drive the lower mold 2 to reset. The upper end of the support base 1 is fixedly installed with a motor 55, and the upper end of the motor 55 is fixedly connected to a cam 56, which contacts the lower mold 2. The defoaming mechanism 5 is designed to eliminate air bubbles in the material.

[0024] The specific implementation process of this utility model is as follows: In use, by starting the motor 55, the output end of the motor 55 drives the cam 56 to rotate, and the cam 56 drives the lower mold 2 to move, which in turn drives the connecting block 51 to move, and the connecting block 51 drives the connecting rod 52 to move, so that the connecting rod 52 slides in the fixed plate 53 and squeezes the spring 54. The elastic force of the spring 54 drives the connecting rod 52 to reset, and the connecting rod 52 drives the lower mold 2 to reset quickly through the connecting block 51, thereby effectively shaking the lower mold 2 and eliminating air bubbles in the material;

[0025] By rotating the knob 45, the knob 45 drives the threaded rod 43 to rotate, causing the threaded rod 43 to move in a threaded motion with the slider 4. This causes the slider 4 to move the locking block 41, allowing the locking block 41 to slide in the slot 42. This removes the locking block 41 from the upper mold 3, thus releasing the upper mold 3 from its limiting position and allowing it to be disassembled.
