[0025] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0026] See also Figure 1-Figure 4 , this embodiment provides a demoulding mechanism, including: an upper mold body 1 and a lower mold body 2, the upper mold body 1 and the lower mold body 2 are used in conjunction with each other;

[0027] Wherein, a demoulding component 4 for demoulding the lampshade is installed between the upper mold body 1 and the lower mold body 2;

[0028] Among them, the bottom of the lower mold body 2 is fixedly connected to the base 3, one end of the base 3 is fixedly connected to the bracket 301, the top of the bracket 301 is installed with a hydraulic cylinder 302, the telescopic rod of the hydraulic cylinder 302 runs through the middle of the bracket 301, and the end of the telescopic rod of the hydraulic cylinder 302 is fixedly connected to the top of the upper mold body 1.

[0029] The demoulding assembly 4 includes a push plate 401, which is arranged between the upper mold body 1 and the lower mold body 2. Four pins 402 are fixedly connected to the bottom of the push plate 401, and the four pins 402 are respectively slidably connected to the four through holes 202 on the lower mold body 2. By providing the push plate 401 and fixing the pins 402 at the bottom of the push plate 401, the pins 402 slide in the through holes 202 on the lower mold body 2, and cooperate with subsequent components to facilitate pushing the molded lampshade shell away from the mold core, so as to facilitate demoulding and taking out the lampshade, and the structure is simple and easy to maintain.

[0030] The surfaces of the four pins 402 are respectively covered with springs 403 and gaskets 404, and the springs 403 are installed between the lower mold body 2 and the gaskets 404. By sleeve-fitting the springs 403 and gaskets 404 on the pins 402, the two ends of the springs 403 are fixedly connected with the gaskets 404 and the lower mold body 2, and used in conjunction with subsequent components, after the upper mold body 1 and the lower mold body 2 are molded, the two are separated, and under the elastic action of the springs 403, the pins 402 are driven to move, so that the push plate 401 at one end of the pins 402 pushes the formed lampshade shell from the mold core, so that the formed lampshade shell is separated from the mold core for easy removal.

[0031] The bottom of the pin 402 is provided with a thread, and a hexagonal nut 405 is screwed on the thread. After the position of the hexagonal nut 405 is adjusted, it is fixedly connected with one end of the gasket 404. By screwing the hexagonal nut 405 on one end of the pin 402, the position of the hexagonal nut 405 on the pin 402 is adjusted in the early stage, so that the elasticity of the spring 403 sleeved on the pin 402 can be adjusted, so that the thrust of the push plate 401 is within a suitable range, so that the demoulding force can be controlled. After the position is adjusted, it is fixedly connected with one end of the gasket 404 to form a whole, so that the elastic force of the spring 403 is fully utilized to separate the formed lampshade shell from the mold core for easy removal.

[0032] Two sliders 101 are respectively installed on both sides of the upper mold body 1, and guide blocks 203 are respectively installed on both sides of the lower mold body 2, and the guide blocks 203 slide between the two sliders 101. By providing the sliders 101 and sliding the guide blocks 203 between the two sliders 101, the upper mold body 1 and the lower mold body 2 can maintain vertical movement when the mold is closed, so that the accuracy of the lampshade shell after molding can be guaranteed.

[0033] Among them, a limiting column 102 is arranged between the two sliders 101, the limiting column 102 is fixedly connected to the upper mold body 1, and a U-shaped groove is arranged in the middle of the guide block 203, and the limiting column 102 is slidably connected in the U-shaped groove. By arranging the limiting column 102 on the upper mold body 1 and making it slide in the middle of the guide block 203, the maximum stroke between the upper mold body 1 and the lower mold body 2 can be limited.

[0034] The working principle of the utility model is as follows: when in use, the hydraulic cylinder 302 is started, so that the telescopic rod end at one end of the hydraulic cylinder 302 pushes the upper mold body 1 and the lower mold body 2 to close the mold. At the same time, the guide blocks 203 on both sides of the lower mold body 2 slide in the sliders 101 on both sides of the upper mold body 1 to make it move vertically up and down. After the upper mold body 1 and the lower mold body 2 are closed, the material is injected into them. After the injection is completed and the material is cooled, the hydraulic cylinder 302 pulls the upper mold body 1 to rise, and at the same time, the push plate 401 is lifted up under the elastic action of the spring, and the lampshade shell on the mold core of the lower mold body 2 is pushed up. The mold is then demoulded, and a hexagonal nut 405 is screwed on one end of the pin 402. By adjusting the position of the hexagonal nut 405 on the pin 402 in the early stage, the elasticity of the spring 403 sleeved on the pin 402 can be adjusted, so that the thrust of the push plate 401 is within a suitable range and the demoulding force can be controlled. After the position is adjusted, it is fixedly connected to one end of the gasket 404 to form a whole, thereby making full use of the elastic force of the spring 403 to separate the molded lampshade shell from the mold core for easy removal.
