Description

Technical Field

[0001] The invention relates to the technical field of glass product forming equipment, and in particular to a glass bottle blow molding device and a demoulding method. Background Art

[0002] Glass bottles can be made using a variety of processes, including blowing, pressing and centrifugal casting; the advantages of blown glass are faster molding speed, the ability to produce thinner glass products, higher production efficiency and more uniform products.

[0003] When glass bottles are mechanically blow-molded, they are divided into the following methods according to their shapes: blow-blowing method, rotary blowing method, belt blowing method, and pressure-blowing method. The blow-blowing method is mostly used to cut small-mouth bottles. The first blowing is carried out in the primary mold to shape the mouth and blow it into a prototype. Then, it is transferred to the forming mold for the second blowing. For the convenience of loading, the primary mold is inverted, so that the upper opening is large and the glass droplets are easy to enter the mold. After loading, the air blowing head quickly moves to the upper part of the funnel and blows air into the primary mold. The compressed air forces the glass material into the mouth mold to form a bottle head. In order to fully fill the glass in the mouth mold, At the same time, the method of vacuuming the mouth mold is used to assist in air blowing; the bottle mouth and air cavity are formed by the rising action of the top core; the symmetry and position of the air cavity will directly affect the uniformity of the wall thickness of the product, and air blowing must be carried out immediately after the loading is completed, otherwise the glass material cannot be filled evenly after cooling and hardening; once the air blowing is completed, the core will immediately withdraw from the mouth mold, and the compressed air will immediately enter the air cavity through the gap between the core and the sleeve, and blow it into a uniform prototype. After the primary mold is fully opened, the flip mechanism will turn 180° in the vertical plane and transfer it to the secondary molding mold for secondary blow molding. The shortcomings of the prior art are that when the mouth of a small-mouthed glass bottle is blow-molded, uneven blowing or other factors may cause the inner wall of the mouth of the glass bottle blank to have uneven thickness. The uneven manufacturing of the mouth of the glass bottle does not meet the molding standards and needs to be crushed and remanufactured, which has certain shortcomings. Summary of the invention

[0028] In the solution further provided by the present invention, the air-blowing component includes a fixed cylinder 71 fixedly connected to the top of the blow molding table 1, a long rod 72 is arranged in the fixed cylinder 71, an air-blowing head 73 is fixedly connected to the top of the long rod 72, and the air-blowing head 73 is connected to the external air supply equipment; a moving block 74 is vertically slidably connected to the blow molding table 1, a wedge groove three 75 is opened in the moving block 74, the wedge block 1 22 contacts with the wedge groove three 75 during its movement, a ring 76 is rotatably connected to the long rod 72, a spring 77 is arranged between the ring 76 and the blow molding table 1, and after the wedge block 1 22 completes the contact with the wedge groove three 75, the wedge block 2 23 can start to contact with the wedge groove 2 52.

[0029] Specifically, a guide unit is provided in the fixed cylinder 71, and the guide unit includes a track groove 81 opened on the inner wall of the fixed cylinder 71, and a guide rod 82 is fixedly connected to the long rod 72, and the guide rod 82 is slidably connected in the track groove 81. The track groove 81 is composed of a spiral part and a vertical groove part spliced ​​together. The structure and movement mode of the secondary blowing component can also be the same as the setting of the air fluttering component.

[0030] A demoulding method based on the above glass bottle blow molding specifically comprises the following steps: S1: After the ingredients fall into the preforming mold, the trigger mechanism moves to first trigger the air blowing component to move and dock with the preforming mold, and cooperates with the air blowing pipe 11 to blow mold the ingredients; S2: The trigger mechanism continues to move to trigger the air blowing pipe 11 and the shaping mechanism to move upward, so that the shaping mechanism moves to the bottle mouth of the blank; S3: The trigger mechanism moves again to trigger the shaping mechanism to rotate and gradually open, shaping the bottle mouth of the blank evenly and smoothly.

[0031] Working principle: during operation, after the blank enters the preforming mold, the wedge block 22 is driven to move and enter the wedge groove 3 75 in the moving block 74 by driving the translation plate 21, and the entry will gradually drive the moving block 74 to drive the long rod 72 to move downward. During the downward movement of the long rod 72, its fixed guide rod 82 will move along the spiral part of the track groove 81 in the fixed cylinder 71, thereby driving the downward moving long rod 72 to drive the air-blowing head 73 to rotate to the top of the preforming mold, and then the guide rod 82 enters the vertical part of the track groove 81. At this time, the long rod 72 drives the air-blowing head 73 to enter the preforming mold to block the top of it, and the wedge block 22 completely enters the wedge groove 3 75 inside the moving block 74. At this time, the wedge block 22 continues to move. The continued movement will not drive the moving block 74 to move downward, and the external air supply device is started to supply air to the air blowing head 73 and the air blowing pipe 11. The air blowing head 73 applies pressure to the blank from above, so that the blank enters the bottom of the preforming mold, and the air blowing pipe 11 blows air to blow an opening in the center of the blank, that is, the bottle mouth. At this time, the translation plate 21 continues to move, so that the wedge block 23 contacts the wedge groove 2 52 on the support plate 51, thereby driving the support plate 51 to move upward. The upward movement of the support plate 51 drives the air blowing pipe 11 to move upward synchronously, and the support plate 51 moves upward. At the same time, the hollow support block 41 abutting against the top thereof will be supported to move upward synchronously, so that the multiple arc-shaped shaping pieces 33 arranged outside the air blowing pipe 11 enter the opening of the blank; When multiple arc-shaped shaping pieces 33 enter the opening of the blank, wedge block 23 completely enters wedge groove 2 52. At this time, wedge block 23 continues to move without driving support plate 51 to move up. Then wedge block 3 24 set on translation plate 21 will enter into wedge groove 1 42 in hollow support block 41. At this time, hollow support block 41 will push disc 31 to move up, and support plate 51 will remain stationary under the action of stretched elastic telescopic rod 2 53. Therefore, the height of blowing tube 11 and arc-shaped shaping piece 33 entering the blank remains unchanged, and the distance between disc 31 and arc-shaped shaping piece 33 is reduced. At this time, the rotating bar 32 can drive the blowing tube 11 to move up. The multiple arc-shaped shaping pieces 33 expand slowly, and can extrude and shape the inner wall of the bottle mouth. When the wedge block 3 24 enters the wedge groove 1 42, the long pressing plate 25 arranged on the wedge block 23 contacts the L-shaped tooth plate 62 and pushes the L-shaped tooth plate 62 to move. The L-shaped tooth plate 62 moves and engages with the long gear 61 arranged on the blowing pipe 11, so that the blowing pipe 11 drives the multiple arc-shaped shaping pieces 33 to rotate. The arc-shaped shaping pieces 33 rotate and drive the disc 31 to rotate on the hollow supporting block 41 through the rotating bar 32. At this time, the multiple arc-shaped shaping pieces 33 rotate while gradually expanding, so that the bottle mouth of the blank can be shaped more smoothly and evenly. After the shaping is completed, the wedge block three 24 is first separated from the wedge groove one 42 on the hollow support block 41, and the hollow support block 41 is reset under the action of the elastic telescopic rod one 43, so that the multiple opened arc-shaped shaping pieces 33 are contracted. At the same time, the thrust of the long pressure plate 25 on the L-shaped tooth plate 62 is reduced. After the L-shaped tooth plate 62 is reset under the action of the elastic telescopic rod three 63, the wedge block two 23 is separated from the wedge groove two 52 on the support plate 51, and under the action of the elastic telescopic rod two 53, the contracted arc-shaped shaping piece 33 and the blowing pipe 11 are driven to reset. Finally, the wedge block one 22 is separated from the wedge groove three 75 in the moving block 74, and the long rod 72 drives the air-blowing head 73 to move up along the shape of the track groove 81 under the action of the spring 77, and then rotates to reset.

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.
