[0022] Example:

[0023] A rotary glass bead automatic press comprises a frame 1, a press body is provided on the upper part of the frame 1, a discharge hopper 15 corresponding to the discharge end of the press body is provided inside, and organic feet 16 are provided at the four corners of the bottom; the press body comprises main splints 5 arranged at relative intervals, a central shaft assembly 6 is provided for rotation at the center of the main splint 5, one end of the central shaft assembly 6 extends out of the main splint 5 and is connected to a power structure driving its rotation, and a cooling water channel 17 is provided through the center of the central shaft assembly 6; a left model column fixing structure 2 and a right model column fixing structure 3 are relatively provided on the part of the central shaft assembly 6 located between the main splints 5, a plurality of groups of left model columns 7 and right model columns 8 are respectively provided in the left model column fixing structure 2 and the right model column fixing structure 3, and a left mold guide rail groove structure 9 and a left demoulding guide groove structure corresponding to the left model column 7 and the right model column 8 are respectively provided on the inner side of the main splint 5. The rail groove structure 10, the left extrusion adjustment bearing structure 11, the right mold closing guide rail groove structure 12, the right demoulding guide rail groove structure 13, and the right extrusion adjustment bearing structure 14 enable the left model column fixed structure 2 and the right model column fixed structure 3 to realize reciprocating mold closing and demoulding when the left model column fixed structure 2 and the right model column fixed structure 3 rotate with the central shaft assembly 6; the power structure includes a passive gear 18 arranged at the end of the central shaft assembly 6 extending out of the main splint 5 and a drive motor 19 arranged in the frame 1, and the output end of the drive motor 19 is provided with a driving gear 20, and the driving gear 20 is connected to the passive gear 18 through a transmission chain (not shown in the figure); the position of the left model column fixed structure 2 and the right model column fixed structure 3 located at the left extrusion adjustment bearing structure 11 and the left extrusion adjustment bearing structure 11 along their rotation direction is the central axis glass solution receiving position, and the external feeding device feeds the material here.

[0024] During specific implementation, the left model column fixing structure and the right model column fixing structure are fixedly installed on the central shaft assembly, and the two ends of the central shaft assembly are supported by the main splint. At the same time, the central shaft assembly is driven to rotate by the drive motor and the transmission chain. The left model column and the right model column are installed in the left model column fixing structure and the right model column fixing structure, and the glass solution is squeezed at the glass solution receiving position of the central shaft under the action of the left mold guide groove structure, the left mold guide groove structure, the left extrusion adjustment bearing structure, and the right extrusion adjustment bearing structure, so as to form the product. During the extrusion process, the left extrusion adjustment bearing structure and the right extrusion adjustment bearing structure can be adjusted to control the mold tightness of the left model column and the right model column. After the product is extruded and formed, it is repeatedly demolded under the action of the left demolding guide groove structure and the right demolding guide groove structure to achieve complete separation of the product from the mold cavity.

[0025] Specifically, the structures of the left model column fixing structure 2 and the right model column fixing structure 3 are the same. The left model column fixing structure 2 includes a guide positioning gear plate 201. The guide positioning gear plate 201 is provided with a fixed flange 202 fixed to the guide positioning gear plate 201 at one end close to the right model column fixing structure 3. Several lubrication grooves 203 are circumferentially penetrated on the fixed flange 202. The left model column 7 is inserted into the lubrication groove 203, and the left model column 7 is clamped in the tooth groove of the guide positioning gear plate 201.

[0026] During specific implementation, the front ends of the left model column and the right model column are fixed in the lubrication groove of the flange, and at the same time, the rear ends of the left model column and the right model column are engaged with the triangular tooth grooves of the guide positioning gear plate; this prevents the left model column and the right model column from swinging when the flange rotates at high speed, causing the press to get stuck and unable to work normally.

[0027] Specifically, the left model column 7 and the right model column 8 are respectively provided with a left motion guide head 21 and a right motion guide head 22 at the ends away from each other. The bottoms of the left motion guide head 21 and the right motion guide head 22 are clamped with the tooth grooves of the guide positioning gear disk 201 in the left model column fixing structure 2 and the right model column fixing structure 3, and the tops respectively correspond to the left mold closing guide rail groove structure 9, the left demolding guide rail groove structure 10, the left extrusion adjustment bearing structure 11 and the right mold closing guide rail groove structure 12, the right demolding guide rail groove structure 13, and the right extrusion adjustment bearing structure 14. The left model column 7 and the right model column 8 are respectively provided with a hemispherical left model cavity 701 and a right model cavity 801 at the ends close to each other. A punching pin 23 is penetrated in the right model column 8, and a side pin slag removal structure 24 corresponding to the position of the punching pin 23 is provided in the left model column 7.

[0028] The side ejector slag discharge structure 24 includes a trapezoidal slag discharge cavity 2401 that is arranged through the side wall of the left model column 7. The side of the trapezoidal slag discharge cavity 2401 away from the seat model cavity is an inclined surface, and the other side is a flat surface. The trapezoidal slag discharge cavity 2401 is connected to the left model column 7 through the left center hole 702, and the left center hole 702 corresponds to the diameter of the punching ejector 23; a punching ejector moving channel 803 is provided in the right model column 8, and the punching ejector moving channel 803 is connected to the right model cavity 801 through the right center hole 802. The diameter of the punching ejector moving channel 803 is larger than the diameter of the right center hole 802, and the punching ejector 23 corresponds to the right center hole 802 and the punching ejector moving channel 803; the punching ejector 23 includes a moving part 2301 that moves in the punching ejector moving channel 803, and an ejection part 2302 that penetrates the right center hole 802 from the left center hole 702.

[0029] During implementation, the guide heads of the left and right mold columns, driven by the left and right mold guide rail structures, push the left and right mold columns toward the center of the device, thereby squeezing the molten glass in the left and right mold cavities and forming it within the mold cavities. Simultaneously, a punching pin passes through the center of the molten glass, pushing the resulting glass residue toward the center hole of the left mold column. This waste glass residue is then discharged through the side ejector slag discharge structure of the left mold column. This side slag discharge structure effectively solves the waste residue discharge problem of the rotary glass bead press mold when producing products with internal holes. This avoids ejector pin breakage caused by poor slag discharge during production.

[0030] Specifically, the left mold closing guide rail groove structure 9 and the right mold closing guide rail groove structure 12 have the same structure. The left mold closing guide rail groove structure 9 includes several track blocks 901 circumferentially arranged outside the guide positioning gear plate 201. A guide groove 902 for the positioning head to pass through is provided on one side of the track block 901 close to the guide positioning gear plate 201. The top of the track block 901 is adjustably connected to the mounting block 903.

[0031] The left demoulding guide rail groove structure 10 includes several track blocks 1001 circumferentially arranged outside the guide positioning gear plate 201, and the track block 1001 is provided with a guide groove 1002 for the positioning head to pass through on one side close to the left model column 7. The guide groove 1002 1002 near one end of the left mold closing guide rail groove structure 9 is the same as the guide groove 1 902. The guide groove 1002 1002 closest to the end of the left extrusion adjustment bearing structure 11 is an arc groove 1 bent toward the right demoulding guide rail groove structure 13. The top of the track block 1001 is adjustably connected to the mounting block 1003. The right demoulding guide rail groove structure 13 includes several track blocks 1001 circumferentially arranged outside the guide positioning gear plate 201. The track block 1001 is provided with a guide groove 1002 for the positioning head to pass through on one side close to the left model column 7. The guide groove 1002 1002 near one end of the left mold closing guide rail groove structure 9 is the same as the guide groove 1 902. The guide groove 1002 closest to the end of the left extrusion adjustment bearing structure 11 is an arc groove 1 bent toward the right demoulding guide rail groove structure 13. The top of the track block 1001 is adjustably connected to the mounting block 1003. The track block three 1301 outside the guide positioning gear disk 201 is provided with a guide groove three 1302 for the positioning head to pass through on the side of the track block three 1301 close to the guide positioning gear disk 201. The guide groove three 1302 is an arc groove two protruding from the middle toward the other gear disk positioning structure. The top of the track block three 1301 is adjustably connected to the mounting block three 1303; the mounting block three 1303, the mounting block two 1003, and the mounting block one 903 are penetrated by an adjustment long hole 24 set along the axial direction of the guide positioning gear disk 201. The mounting block three 1303, the mounting block two 1003, and the mounting block one 903 are connected to the adjustment long hole 24 by bolts.

[0032] The left extrusion adjustment bearing structure 11 and the right extrusion adjustment bearing structure 11 have the same structure. The left extrusion adjustment bearing structure 11 includes a bearing body 1101, which is rotatably set on the bearing back plate 1102. The bearing back plate 1102 is adjustably connected to the bearing frame 1103. A bearing positioning plate 1104 corresponding to the bearing back plate 1102 is set on the upper edge of the bearing frame 1103, so that the bearing back plate 1102 can be adjusted along the axial direction of the guide positioning gear plate 201. The bearing positioning plate 1104 is connected to the bearing frame 1103 by bolts.

[0033] During specific implementation, the left model column and the right model column are guided to the left extrusion adjustment bearing structure and the right extrusion adjustment bearing structure through the left demolding guide rail groove structure and the right demolding guide rail groove structure. The left model column and the right model column move inward when passing through the left extrusion adjustment bearing structure and the right extrusion adjustment bearing structure to complete the extrusion molding of the product. When passing through the left demolding guide rail groove structure and the right demolding guide rail groove structure, the model column forms multiple reciprocating motions due to the action of the reciprocating guide groove in the demolding guide track, thereby completely separating the glass bead product from the mold cavity. This multiple reciprocating demolding structure solves the problem of secondary extrusion damaging the mold due to incomplete product demolding.

[0034] This rotary glass bead automatic pressing machine has a simple structure, is easy to assemble and disassemble, has good machine operation stability, produces no waste residue and pollution, has low energy consumption (1.KW), is fully automated, and has high production efficiency. The invention of this machine has completely changed the traditional glass bead production model with high energy consumption, low efficiency, and a lot of waste residue and dust.

The drawings show only one embodiment of the present invention, and the actual structure is not limited thereto. In short, if a person skilled in the art is inspired by this and, without departing from the purpose of the present invention, designs structures and embodiments similar to this technical solution without inventiveness, they shall fall within the scope of protection of the present invention.
