DETAILED DESCRIPTION

[0035] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0036] See also Figure 1-5 As shown, the present invention is a large-size hemispherical glass molding press, comprising a frame 1, an L-shaped support plate 3 is fixedly installed on one side of the frame 1, and a liftable upper mold mechanism 4 is fixedly installed on the L-shaped support plate 3;

[0037] Specifically, a lower mold mechanism 2 is slidably connected to the frame 1, and two slide rails 11 are symmetrically installed on the frame 1. The lower mold mechanism 2 includes a sliding plate 21, which is slidably connected to the slide rail 11, and the sliding plate 21 can be pushed to move by a cylinder. A hollow disk 22 is fixedly installed on the sliding plate 21, and the internal array of the hollow disk 22 is provided with a plurality of threaded rods 213, and a pushing sleeve 214 is threadedly connected to the threaded rod 213. A slider 215 is fixedly installed on the end of the pushing sleeve 214, and the slider 215 is provided to play a supporting and sliding role. A central arc plate 216 is fixedly installed on the top of the slider 215, and the central arc plate 216 passes through the hollow disk 22. A slide groove 23 is provided between the central arc plate 216 and the hollow disk 22, and a lower mold 25 is placed on the central arc plate 216.

[0038] In this embodiment, the threaded rod 213 is driven to rotate, driving the push sleeve 214 to move horizontally, and the push sleeve 214 drives the central arc plate 216 to move, thereby adjusting the distance between the central arc plates 216, thereby facilitating the use of lower molds 25 of different diameters, and having strong applicability.

[0039] Example 2

[0040] Based on Example 1, please refer to Figure 4 As shown, the internal array of the hollow disk 22 is provided with a plurality of transmission wheels 210, and the transmission wheels 210 are rotatably connected with the hollow disk 22. A driving wheel 28 is also provided inside the hollow disk 22, and the driving wheel 28 is driven to rotate by a servo motor 24 installed on the top of the hollow disk 22. The driving wheel 28 is rotatably connected with the hollow disk 22. A belt 29 is sleeved on the plurality of transmission wheels 210 and the driving wheels 28. A bevel gear 1 211 is fixedly installed on the transmission wheel 210, and a bevel gear 212 is meshedly connected to the bevel gear 1 211. A threaded rod 213 is fixedly installed on one end of the bevel gear 212, and the other end of the bevel gear 212 is rotatably connected with the hollow disk 22 through a rotating shaft, so as to ensure the stability of the rotation of the bevel gear 212.

[0041] In this embodiment, the servo motor 24 is started to drive the driving wheel 28 to rotate, and the driving wheel 28 drives the transmission wheel 210 to rotate through the belt 29. The transmission wheel 210 rotates and then drives the bevel gear 1 211 to rotate, the bevel gear 1 211 drives the bevel gear 212 to rotate, and the bevel gear 212 drives the threaded rod 213 to rotate, thereby realizing synchronous driving, so that the center arc plate 216 can be synchronously driven to move, ensuring that the moving distance is the same, which is suitable for lower molds 25 of different diameters; because if it is adjusted separately, it will result in different adjustment distances, which will make the lower mold 25 unstable; therefore, the setting of this structure is to facilitate the replacement of the lower mold 25.

[0042] Specifically, side arc plates 217 are symmetrically arranged on both sides of the central arc plate 216, and the length of the side arc plates 217 is smaller than that of the central arc plate 216; the two side arc plates 217 slide on the surface of the hollow disk 22, which will play a good supporting role.

[0043] Specifically, the top array of the hollow disk 22 is installed with a plurality of horizontally arranged pushing cylinders 218, and the pushing cylinders 218 are cross-arranged with the central arc plate 216. A lifting cylinder 219 is vertically installed on the piston rod of the pushing cylinder 218, and a limiting wheel 220 is fixedly installed on the piston rod of the lifting cylinder 219.

[0044] In this embodiment, the pushing cylinder 218 is started to drive the lifting cylinder 219 to move horizontally, and then the lifting cylinder 219 is started to move up and down, thereby driving the limiting wheel 220 to move, and the limiting wheel 220 is brought into contact with the edge of the lower mold 25 to limit it, so that it will not shake during the rotation and cooling molding process. Through the setting of this scheme, the position of the limiting wheel 220 can be adjusted to suit lower molds 25 of different diameters, and the limiting wheel 220 only needs to contact the edge of the lower mold 25, and the position does not need to be completely consistent, so there is no need for synchronous adjustment.

[0045] For details, please refer to Figure 3 and Figure 6 As shown, a cooling water tank 26 is fixedly installed at the bottom of the sliding plate 21, a water pump is arranged inside the cooling water tank 26, a plug-in tube 27 is fixedly installed on the top of the cooling water tank 26, the water pump is connected to the plug-in tube 27, the plug-in tube 27 is inserted into the plug-in tube 252 arranged at the bottom of the lower mold 25, and sealing rings are arranged on the plug-in tube 252 and the plug-in tube 27, and a hollow cavity 251 is formed inside the lower mold 25. When the lower mold 25 is placed, the plug-in tube 27 is just inserted into the plug-in tube 252. During the cooling and molding process, the water pump draws cold water into the hollow cavity 251 through the plug-in tube 27 and the plug-in tube 252 to cool the lower mold 25 and accelerate molding.

The adjusting cylinder 42 is started to drive the upper die 41 to rise and fall, and the arrangement of the T-shaped slider 43 and the arc groove 44 facilitates the rotation of the upper die 41 on the one hand, and can play a good supporting role on the other hand. The upper die mechanism 4 is connected to the L-shaped support plate 3 by bolts, which is convenient for disassembly and replacement.

[0048] The outer portion of the hollow transmission tube 45 is sleeved with a gear ring 46, and the gear ring 46 is meshedly connected with a transmission gear 47, and the transmission gear 47 is driven to rotate by a rotary motor;

A cooling water pipe 32 is fixedly installed on the top of the cooling water tank 2 31. One end of the water pump is connected to the cooling water pipe 32. The cooling water pipe 32 passes through the hollow transmission pipe 45, extends into the upper mold 41, and is rotatably connected to the spiral coil 48 embedded and installed inside the upper mold 41. The distance between the spiral coil 48 and the outer surface of the upper mold 41 is 5CM. The diameter of the spiral coil 48 decreases from top to bottom, and the diameter of the spiral coil 48 decreases from top to bottom. Figure 7 It can be clearly seen that an L-shaped tube is provided at the center of the upper end of the spiral coil 48, which is rotatably connected to the cooling water pipe 32. When the upper mold 41 rotates and drives the spiral coil 48 to rotate, it does not affect the cooling water pipe 32.

[0051] In this embodiment, cold water is pumped into the cooling water pipe 32 by a water pump and then enters the spiral coil 48. The spiral coil 48 is provided to increase its length and improve its cooling effect, and is driven to rotate so as to make the cooling more uniform.
