Detailed Implementation

[0016] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0017] like Figures 1-14As shown, a mold with a spiral mold opening structure includes a base 1, a bottom mold 2 fixedly connected to the upper side of the base 1, a top mold 3 overlapping the upper side of the bottom mold 2, an upper mold mechanism 4 overlapping the upper side of the top mold 3, a demolding mechanism 5 rotatably connected to the inner side of the bottom mold 2, an injection table 6 fixedly connected to the inner side of the base 1, and a water cooling mechanism 7 movably installed on the rear side of the base 1. The upper mold mechanism 4 includes an upper mold cover 41. Several annularly distributed rotating blocks 42 are rotatably connected to the inner side of the upper mold cover 41. A first connecting platform 43 is fixedly connected to the lower side of the rotating blocks 42. Several annularly distributed first modules 44 are fixedly connected to the lower side of the first connecting platform 43. A second connecting platform 45 is movably sleeved on the outer side of the first modules 44. Several annularly distributed second modules 46 are fixedly connected to the lower side of the second connecting platform 45. The outer side of the second connecting platform 45 is rotatably connected to the inner side of the top mold 3.

[0018] It should be noted that the water cooling mechanism 7 is used to accelerate the cooling of the model and is existing technology, so it will not be described in detail here. A lifting device or a pressing device is used. The lifting device or pressing device can be composed of plates driven by hydraulic rods. The plates are pressed down on the upper mold cover 41 by the hydraulic rods, so that the base 1, the bottom mold 2, and the upper mold cover 41 are tightly fitted together. When the lifting device or pressing device is disengaged from the upper mold cover 41, the upper mold cover 41 is lifted up, so that the upper mold cover 41 drives the rotating block 42 to move upward, thereby causing the first module 44 to detach from the wax model.

[0019] like Figure 9 As shown, a number of first guide rods 49 arranged in a ring are fixedly connected to the outer side of the second connecting platform 45. A guide seat 410 is slidably connected to the outer side of each of the first guide rods 49. The lower side of the guide seat 410 is fixedly connected to the upper side of the bottom mold 2.

[0020] It should be noted that after the rotating block 42 is raised, rotating the rotating block 42 causes the first module 44 to drive the second connecting platform 45 to rotate. Due to the presence of the guide seat 410, the second connecting platform 45 is guided by the guide seat 410 when rotating, so that the second connecting platform 45 moves upward while rotating, thereby causing the second module 46 to detach from the wax film.

[0021] like Figure 5 As shown, the bottom of the upper mold cover 41 is fixedly connected with several evenly distributed first telescopic rods 47, and the outer sides of the several first telescopic rods 47 are movably sleeved with first springs 48.

[0022] It should be noted that the bottom of the first telescopic rod 47 is fixedly connected to the inner side of the top mold 3. When the lifting device or the pressing device is disengaged from the upper mold cover 41, the first spring 48 pushes the upper mold cover 41 upward, so that the upper mold cover 41 and the top mold 3 are automatically separated, making it convenient to rotate the rotating block 42.

[0023] like Figure 10, Figure 11 As shown, the demolding mechanism 5 includes a turntable 51, the outer side of which is rotatably connected to the inner side of the bottom mold 2. Several annularly distributed sliders 52 are slidably connected to the upper side of the bottom mold 2. Side modules 53 are fixedly connected to the upper side of each slider 52. Several annularly distributed arc-shaped grooves are opened on the upper side of the turntable 51. The lower module 54 is rotatably connected to the upper middle part of the base 1.

[0024] It should be noted that the lower side of the slider 52 is synchronously slidably connected in the arc groove. Rotating the turntable 51 causes the sliders 52 to move closer or further away from each other, thereby causing the side module 53 to move closer or further away from the lower module 54.

[0025] like Figure 11 As shown, a pusher seat 55 is movably sleeved on the outer side of the upper mold mechanism 4. Several ring-shaped push blocks 58 are overlapped in the inclined groove on the lower side of the pusher seat 55. The lower side of the push blocks 58 is fixedly connected to the upper side of the turntable 51.

[0026] It should be noted that when the turntable 51 rotates, it drives the push block 58 to rotate. When the push block 58 rotates, it overlaps in the inclined groove on the lower side of the push base 55, so that the rotation of the push block 58 drives the rotation of the push base 55, thereby pushing out the wax model.

[0027] like Figure 13 As shown, the bottom of the lower module 54 has several annularly distributed guide grooves 57, and the inner side of the push base 55 is fixedly connected to several annularly distributed second guide rods 56, and the outer side of the second guide rods 56 is slidably connected to the inner side of the guide grooves 57.

[0028] It should be noted that when the push base 55 moves upward, it drives the second guide rod 56 to move upward. The second guide rod 56 is slidably connected to the inside of the guide groove 57, so that when the second guide rod 56 moves upward, it drives the lower module 54 to rotate, so that when the wax model is ejected, the lower module 54 moves out of the wax model.

[0029] like Figure 13 As shown, a number of second telescopic rods 59 arranged in a ring are fixedly connected to the upper side of the base 1. The upper side of the second telescopic rods 59 is fixedly connected to the inner side of the push seat 55, and a second spring 510 is movably sleeved on the outer side of each of the second telescopic rods 59.

[0030] It should be noted that the second spring 510 is a tension spring, which allows the push block 58 to be stably reset when it is reset.

[0031] The working principle of this utility model is as follows: First, when the lifting device or pressing device disengages from the upper mold cover 41, the upper mold cover 41 is lifted, causing the upper mold cover 41 to move the rotating block 42 upward, thereby causing the first module 44 to disengage from the wax model. After the rotating block 42 is lifted, it is rotated, causing the first module 44 to drive the second connecting platform 45 to rotate. Due to the presence of the guide seat 410, the second connecting platform 45 is guided by the guide seat 410 when rotating, causing the second connecting platform 45 to rotate and move upward, thereby causing the second module 46 to disengage from the wax film. When the pusher 55 moves upward, it drives the second guide rod 56 to move upward. The second guide rod 56 is slidably connected to the inside of the guide groove 57, so that when the second guide rod 56 moves upward, it drives the lower module 54 to rotate, so that when the wax model is ejected, the lower module 54 moves out of the wax model. Through the self-rotation of the second connecting platform 45 when the upper mold cover 41 is lifted, and the pusher 55 when the turntable 51 is rotated, the second module 45 moves upward. The rotation of the lower module 54 causes the spiral structure on the wax model to move out from the inside of the first module 44, the second module 46, and the lower module 54, avoiding the problems of manual disassembly, which would lead to difficulties in disassembling the wax model and potential damage to the wax model. Finally, the lower side of the slider 52 is synchronously slidably connected in the arc groove. Rotating the turntable 51 causes the sliders 52 to move closer or further apart, thereby causing the side module 53 to move closer or further away from the lower module 54. When the turntable 51 rotates, it drives the push block 58 to rotate. When the push block 58 rotates, it overlaps in the inclined groove on the lower side of the push seat 55, causing the push block 58 to rotate and drive the push seat 55 to rotate, thus pushing out the wax model. By rotating the turntable 51, the side module 53 moves away from the wax model, and the push seat 55 pushes the wax model up, thus allowing the wax model to demold itself, improving production efficiency. Combined with the spiral structure, it achieves the synchronous function of spiral module separation and wax model demolding.

Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claims.
