[0022] See also Figure 1-8A rotary forming device for producing lightweight glass cups includes a base 1 and a turntable 11, the base 1 is rotatably connected to the turntable 11, a fixed seat 3 is arranged on the turntable 11, and a mold 31 is rotatably arranged on the fixed seat 3; a reciprocating rod 4 is slidably arranged on the turntable 11, a sliding block 41 is slidably arranged on the reciprocating rod 4, a plug pin 42 is fixedly arranged on the sliding block 41, and a plug hole 32 is arranged on the mold 31, and the plug pin 42 is plugged with the plug hole 32; a lifting rod 5 is slidably arranged on the turntable 11, and the lifting rod 5 is slidably connected to the reciprocating rod 4; and a pressing assembly is also included, which is used to lower the plurality of lifting rods 5 and the reciprocating rod 4 to complete the disengagement of the plug pin 42 from the plug hole 32, and when the mold 31 is replaced , by pressing down the assembly, multiple lifting rods 5 are lowered with the corresponding reciprocating rods 4 and the sliding blocks 41 on the reciprocating rods 4, so that the plug pins 42 on the sliding blocks 41 are disengaged from the plug holes 32 on the mold 31, so that the mold 31 is disengaged from its opening and closing drive, which greatly improves the efficiency of replacing the mold 31; in the process of producing glass cups, the reciprocating rod 4 is used to slide the sliding blocks 41, and the plug pins 42 on the sliding blocks 41 are plugged into the plug holes 32, so that the two molds 31 are rotated on the fixed seat 3, so that the molds 31 are merged or opened. In this process, the sliding blocks 41 slide on the reciprocating rod 4 while sliding with the reciprocating rod 4.

[0023] Specifically, a third spring 51 is provided between the lifting rod 5 and the turntable 11, and the two ends of the third spring 51 are fixedly connected to the lifting rod 5 and the turntable 11 respectively. During the production process of the glass cup, the third spring 51 is in a normal state, so that the plug pin 42 on the sliding block 41 is plugged into the plug hole 32 on the mold 31. At this time, the reciprocating rod 4 can merge or open the two molds 31 by sliding. When the mold 31 is replaced, the lifting rod 5 moves downward, and moves the reciprocating rod 4 downward, so that the plug pin 42 on the sliding block 41 is disengaged from the plug hole 32 on the mold 31, so as to facilitate the disassembly of the mold 31.

[0024] In an embodiment further provided by the present invention, the pressing assembly includes a fixed rod 2 fixedly set on the base 1, a top plate 21 is slidably set on the fixed rod 2, and multiple lifting rods 5 are all in contact with the top plate 21; a first spring 24 is arranged between the top plate 21 and the fixed rod 2, and the two ends of the first spring 24 are respectively fixedly connected to the top plate 21 and the fixed rod 2. When the mold 31 is replaced, the top plate 21 is moved downward, the first spring 24 is squeezed, and the multiple lifting rods 5 are pressed downward at the same time. By moving the top plate 21 downward, the multiple molds 31 and their opening and closing drives can be disassembled at the same time, which is convenient for replacing the mold 31.

[0025] Furthermore, a contact block 43 is slidably provided on the reciprocating rod 4, a hydraulic rod 7 is fixedly provided on the fixed rod 2, a contact plate 71 is fixedly provided on the telescopic end of the hydraulic rod 7, and the contact plate 71 contacts the contact block 43. During the rotation of the turntable 11, the reciprocating rod 4 rotates. When it rotates to the position where the contact block 43 corresponds to the contact plate 71, the turntable 11 stops rotating, and through the contraction of the hydraulic rod 7, the contact plate 71 contacts the contact block 43 and pushes the contact block 43, so that the contact block 43 slides with the reciprocating rod 4, thereby realizing the rotation and opening and closing of the mold 31.

[0026] Furthermore, a protrusion 72 is fixedly provided on the support plate 71, and a sliding groove is provided on the top plate 21. The protrusion 72 is slidably set in the sliding groove. The sliding groove includes a straight portion 22 and an inclined portion 23. During the production process of the glass cup, the support plate 71 and the abutment block 43 are abutted and matched by the extension and contraction of the hydraulic rod 7 to realize the opening and closing of the mold 31. During this process, the protrusion 72 only slides in the straight portion 22. When the mold 31 is replaced, the hydraulic rod 7 continues to contract, the support plate 71 is disengaged from the abutment block 43, and the protrusion 72 enters the inclined portion 23 from the straight portion 22. Under the action of the inclined portion 23, the top plate 21 is moved downward, and the downward movement of the lifting rod 5 is completed, so that the plug pin 42 on the sliding block 41 is disengaged from the plug hole 32 of the corresponding mold 31.

[0027] In an embodiment further provided by the present invention, a straight rod 8 is fixedly provided on the fixed rod 2, and an inclined surface is provided on the abutment block 43, and the straight rod 8 abuts against the inclined surface. When the hydraulic rod 7 contracts, the abutment plate 71 slides with the reciprocating rod 4 by abutting against the abutment block 43 to open the mold 31. After the mold 31 is completely opened, the abutment block 43 simultaneously completes sliding under the abutment action of the straight rod 8 and the inclined surface, that is, it disengages from the abutment plate 71. At this time, the hydraulic rod 7 can continue to contract, so that the protrusion 72 enters the inclined portion 23 from the straight portion 22, so that the top plate 21 moves downward. When the mold 31 is not replaced, after the mold 31 is opened, the hydraulic rod 7 can be reset with the abutment plate 71.

[0028] In the embodiment provided by the present invention, a plurality of second springs 44 are arranged between the abutment block 43 and the reciprocating rod 4, and the two ends of the second spring 44 are fixedly connected to the abutment block 43 and the reciprocating rod 4, respectively. When the reciprocating rod 4 slides and the inclined surface of the abutment block 43 abuts against the straight rod 8, the abutment block 43 slides under the action of the inclined surface and squeezes the second spring 44. After the reciprocating rod 4 slides to complete the opening of the mold 31, the abutment block 43 slides to disengage from the abutment plate 71. At this time, the hydraulic rod 7 can continue to contract to move the top plate 21 downward, or it can extend and reset to cooperate with the abutment block 43 on the next reciprocating rod 4 to open the next mold 31.

[0029] Specifically, a fixing frame 6 is fixedly provided on the fixing rod 2, a guide groove is provided on the fixing frame 6, a guide rod 45 is fixedly provided on the reciprocating rod 4, the guide rod 45 is arranged in the guide groove, and the guide groove includes a mold clamping part 61, an opening part 62, a mold opening part 63 and a merging part 64. When the guide rod 45 is located at the mold clamping part 61, the mold 31 is in a merged state, and the glass can be molded. Under the expansion and contraction of the hydraulic rod 7 and the cooperation of the abutment plate 71 and the abutment block 43, the guide rod 45 slides from the connection point of the mold clamping part 61 and the opening part 62 to the connection point of the opening part 62 and the mold opening part 63. In this process, the mold 31 is opened, and the mold can be The glass cup formed in 31 is taken out, and when the guide rod 45 is located at the connection point between the opening part 62 and the mold opening part 63, under the action of the straight rod 8, the abutment block 43 is separated from the abutment plate 71. At this time, whether the hydraulic rod 7 continues to shrink or stretch and reset, it has no effect on the reciprocating rod 4. When the guide rod 45 is located at the mold opening part 63, the mold 31 is in an open state. At this time, the inner wall of the mold 31 can be cleaned. After the guide rod 45 enters the merging part 64, the reciprocating rod 4 slides to merge the two molds 31 until the guide rod 45 enters the closing part 61 from the merging part 64. The mold 31 is merged and the glass cup can be molded again.

[0030] Furthermore, a gear ring 13 is fixedly provided on the turntable 11, a motor 9 is fixedly provided on the base 1, a gear 91 is fixedly provided on the output shaft of the motor 9, the gear 91 is meshed with the gear ring 13 for transmission, and the turntable 11 is rotated by the motor 9 through the transmission of the gear 91 and the gear ring 13, so that the guide rod 45 cooperates with the guide groove to realize the opening and closing of the mold 31, so as to complete the molding and demolding of the glass cup.

[0031] A positioning block 12 is fixedly provided on the turntable 11, and a positioning groove 33 is provided on the fixing seat 3. The positioning block 12 is adapted to the positioning groove 33. Through the cooperation of the positioning block 12 and the positioning groove 33, the fixing seat 3 and the mold 31 can be placed more conveniently and accurately during installation. After the fixing seat 3 is placed and installed, the plug hole 32 on the mold 31 is aligned with the plug pin 42 on the corresponding sliding block 41. Subsequently, the hydraulic rod 7 is extended, and the protrusion 72 enters the straight portion 22 from the inclined portion 23, and the top plate 21 rises. Under the action of the third spring 51, the lifting rod 5 moves up with the reciprocating plate to complete the plugging of the plug pin 42 and the plug hole 32. A truncated cone portion is provided on the plug pin 42, such as Figure 8 As shown, the plug pin 42 can be plugged into the plug hole 32 more conveniently.

[0032] It should be noted that there is a certain gap between the top plate 21 on the hydraulic rod 7 and the abutment block 43. When the turntable 11 rotates with the reciprocating rod 4, when the hydraulic rod 7 is in an extended state, the reciprocating rod 4 rotates with the turntable 11, so that the abutment block 43 moves to correspond to the abutment plate 71. During this process, the abutment block 43 and the abutment plate 71 do not interfere with each other, that is, the abutment rod does not affect the rotation of the reciprocating rod 4 and the abutment block 43; the mold 31 mentioned in the present invention is provided with two on each fixed seat 3, and the two molds 31 are combined for the molding of the glass cup, and the rotation, opening or merging of the two molds 31 are controlled by the sliding of the reciprocating rod 4.

[0033] Working principle: When the glass is produced and formed, the motor 9 drives the gear ring 13 through the gear 91 to rotate the turntable 11. During the rotation process, when the guide rod 45 is located at the mold closing part 61, the two molds 31 on the fixed seat 3 are merged. At this time, the glass can be formed in the mold 31. After forming, the turntable 11 continues to rotate. When the guide rod 45 rotates to the connection between the mold closing part 61 and the opening part 62, the turntable 11 stops rotating, and then the hydraulic rod 7 contracts, and the abutment plate 71 abuts against the abutment block 43, pulling the reciprocating rod 4 and the guide rod 45 to slide, so that the guide rod 45 slides to the connection between the opening part 62 and the mold opening part 63. In this process, the reciprocating rod 4 slides with the guide rod 45, and is connected with the plug pin 42 on the sliding block 41. The cooperation of the connecting hole 32 opens the two molds 31 so that the glass cup can be demoulded and taken out after being formed. Subsequently, the hydraulic rod 7 is reset, the turntable 11 continues to rotate, and the guide rod 45 slides in the mold opening part 63. During this process, the two molds 31 are in an open state, and the interior can be cleaned. During the continuous rotation of the turntable 11, the guide rod 45 enters the merging part 64 from the mold opening part 63. Because the merging part 64 is inclined, when the guide rod 45 slides in the merging part 64, the reciprocating rod 4 slides on the turntable 11 at the same time, and the two molds 31 are merged through the cooperation of the plug pin 42 on the sliding block 41 and the plug hole 32. When the guide rod 45 enters the mold closing part 61 from the merging part 64, the two molds 31 are merged, and the glass cup can be formed again; When the mold 31 is replaced, the turntable 11 stops rotating, the hydraulic rod 7 contracts, and the protrusion 72 on the abutment plate 71 slides along the straight portion 22 and enters the inclined portion 23. The hydraulic rod 7 continues to contract. Under the action of the inclined portion 23, the top plate 21 moves downward and squeezes the first spring 24. At the same time, the top plate 21 pushes the lifting rod 5 downward to stretch the third spring 51. In the process of moving downward, the reciprocating rod 4 also moves downward, so that the plug pin 42 of the sliding block 41 is disengaged from the abutment block 43. At this time, the fixed seat 3 and the mold 31 can be disassembled, which greatly improves the efficiency of replacing the mold 31. It should be noted that during the replacement of the mold 31, the hydraulic rod 7 slides with the reciprocating rod 4 and the guide rod 45 through the abutment between the abutment plate 71 and the abutment block 43. When the guide rod 45 moves to the connection between the opening portion 62 and the mold opening portion 63, the abutment block 43 completes the sliding under the abutment action of the inclined surface and the straight rod 8, and squeezes the second spring 44. At this time, the abutment block 43 does not abut against the abutment plate 71, and will not affect the continued contraction of the hydraulic rod 7, so that the hydraulic rod 7 can continue to contract, so that the protrusion 72 of the abutment plate 71 enters the inclined portion 23 from the straight portion 22, and completes the disengagement of each plug pin 42 from the plug hole 32.

[0034] The above description is only by way of illustration of certain exemplary embodiments of the present invention. It is undoubted that those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
