Description

Technical Field

[0001] This patent relates to the field of demolding mechanism technology, specifically a demolding mechanism for glass molding. Background Technology

[0002] During the production of glass containers, a certain amount of molten glass is poured into a molding shell, and then a molding cap is pressed into the molding shell to mold the glass into the shape of a container. In order to facilitate the demolding of the glass container after cooling, a top column is set at the bottom of the molding shell. The glass container is demolded by the upward movement of the top column. However, there is a lot of friction between the outer wall of the glass container and the inner wall of the molding shell. During the movement of the glass container, a lot of friction is caused to the outer wall of the container, which affects the product quality. To address this, we propose a glass molding demolding mechanism. Utility Model Content

[0003] The purpose of this patent is to provide a glass molding demolding mechanism to solve the problems mentioned in the background art.

[0004] To achieve the above objectives, this patent provides the following technical solution: a glass molding demolding mechanism, comprising a molding cover and a molding shell, wherein a short side plate and a long side plate are hinged to the inner bottom wall of the molding shell, and there are two of each of the short side plate and the long side plate, which are combined to form a cuboid shell. The outer surfaces of the short side plate and the long side plate are provided with wheel grooves and expansion grooves, and the bottom end of the wheel groove is connected to the top end of the expansion groove.

[0005] The outer side wall of the molded housing is provided with a drive mechanism on all four sides. A wheel seat is connected to the drive mechanism. A support wheel is connected to the wheel seat through a rotating shaft. The inner contour of the wheel groove matches the contour of the wheel body edge of the support wheel. The four support wheels are respectively rolled and installed in the four wheel grooves at the wheel body edges.

[0006] Preferably, the end of the long side plate is provided with a corner groove, and the end of the short side plate is inserted into the corner groove.

[0007] Preferably, one end of a spring is installed on the outer side of both the short side plate and the long side plate, and the other end of the spring is fixedly installed on the four sides of the inner side wall of the molded housing, with the spring in an extended state.

[0008] Preferably, hinge seats are installed at both ends of the spring.

[0009] Preferably, the drive mechanism includes a mounting base, which is fixedly mounted on the outer side wall of the molding housing. A cylinder is fixedly mounted on the top of the mounting base, and a crossbar is fixedly mounted on the top of the piston rod of the cylinder. Slotted holes are provided on all four sides of the side wall of the molding housing, and the inner end of the crossbar passes through the slotted holes and is fixedly mounted on the outer side of the wheel seat.

[0010] Preferably, the crossbar includes a connecting column and a square rod. The bottom end of the side wall of the connecting column is connected to the top end of the piston rod of the cylinder. One end of the connecting column is provided with a square groove, and the other end of the connecting column is provided with a round hole. A bearing is fixedly installed on the inner side wall of the round hole, and a threaded rod is fixedly installed on the inner side wall of the inner ring of the bearing. The side wall of the square rod slides against the inner side wall of the square groove. One end of the square rod located in the square groove is provided with a threaded groove, and the threaded groove is screwed to the threaded rod. The other end of the square rod is connected to the outer side of the wheel seat.

[0011] Compared with the prior art, the beneficial effects of this patent are as follows: This patent has two long side plates and a short side plate inside the molding shell. The bottom of the four plates are all hinged to the bottom of the molding shell. The four plates are combined to form the shape of the glass container to be pressed. The outer sides of the long side plates and the short side plates are provided with wheel grooves. The bottom of the wheel grooves is provided with expansion grooves. Support wheels controlled by a drive mechanism are rolled in the wheel grooves. After the glass container is pressed, the support wheels can be moved downward by the drive mechanism so that the support wheels no longer roll in the wheel grooves. At this time, the spring rebound effect causes the four plates to flip along the hinge point position, so that the inner sides of the long side plates and the short side plates are no longer in contact with the outer side wall of the glass container, which facilitates the demolding of the glass container and avoids wear on the container.

[0017] The technical solutions of this patent embodiment will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this patent, and not all of them. Based on the embodiments of this patent, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this patent.

[0018] Please see Figure 1 , Figure 2 , Figure 3 and Figure 4 This patent provides a technical solution: a glass molding demolding mechanism, including a molding cover 1 and a molding shell 2. The inner bottom wall of the molding shell 2 is hinged with a short side plate 3 and a long side plate 4. There are two short side plates 3 and two long side plates 4. The two short side plates 3 and the long side plates 4 are combined to form a cuboid shell. The outer surfaces of the short side plates 3 and the long side plates 4 are provided with wheel grooves 5 and expansion grooves 6. The bottom end of the wheel groove 5 is connected to the top end of the expansion groove 6.

[0019] like Figure 1 As shown, the width of the expansion groove 6 is greater than the width of the wheel groove 5. When the support wheel 8 moves downward into the expansion groove 6, the support wheel 8 will no longer support the short side plate 3 and the long side plate 4. At this time, the short side plate 3 and the long side plate 4 can be flipped along the position of the hinge point.

[0020] The outer side wall of the molded housing 2 is provided with a drive mechanism on all four sides. A wheel seat 7 is connected to the drive mechanism. A support wheel 8 is connected to the wheel seat 7 through a rotating shaft. The inner contour of the wheel groove 5 matches the contour of the wheel body edge of the support wheel 8. The wheel body edges of the four support wheels 8 are respectively rolled and installed in the four wheel grooves 5.

[0021] Specifically, the end of the long side plate 4 is provided with a corner groove 9, and the end of the short side plate 3 is inserted into the corner groove 9.

[0022] By setting the end of the short side plate 3 to be inserted into the corner groove 9, the sealing effect between the ends of the long side plate 4 and the short side plate 3 can be increased.

[0023] Specifically, one end of a spring 10 is installed on the outer side of both the short side plate 3 and the long side plate 4, and the other end of the spring 10 is fixedly installed on the four sides of the inner wall of the molded housing 2, with the spring 10 in an extended state.

[0024] Figure 1 The spring 10 is in an extended state. When the support wheel 8 enters the expansion groove 6, the short side plate 3 and the long side plate 4 can automatically flip along the hinge point position through the rebound effect of the spring 10.

[0025] Specifically, hinge seats are installed at both ends of the spring 10.

[0026] Since the short side plate 3 and the long side plate 4 are in a flipping motion, if the spring 10 is fixedly connected to the short side plate 3 and the long side plate 4, the long-term movement will cause the spring 10 to twist and be damaged. However, with the setting of the hinge, when the short side plate 3 and the long side plate 4 are flipped, the spring 10 will move and change position according to the setting of the hinge, thus avoiding its own twisting and damage.

[0027] Specifically, the drive mechanism includes a mounting base 11, which is fixedly mounted on the outer side wall of the molding housing 2. A cylinder 12 is fixedly mounted on the top of the mounting base 11, and a crossbar 13 is fixedly mounted on the top of the piston rod of the cylinder 12. The four sides of the side wall of the molding housing 2 are provided with strip holes, and the inner end of the crossbar 13 passes through the strip holes and is fixedly mounted on the outer side of the wheel seat 7.

[0028] Specifically, the crossbar 13 includes a connecting post 14 and a square rod 18. The bottom end of the side wall of the connecting post 14 is connected to the top end of the piston rod of the cylinder 12. One end of the connecting post 14 is provided with a square groove 15, and the other end of the connecting post 14 is provided with a round hole. A bearing 16 is fixedly installed on the inner side wall of the round hole. A threaded rod 17 is fixedly installed on the inner side wall of the inner ring of the bearing 16. The side wall of the square rod 18 is in relative contact with the inner side wall of the square groove 15 and slides. One end of the square rod 18 located in the square groove 15 is provided with a threaded groove 19. The threaded groove 19 is screwed to the threaded rod 17. The other end of the square rod 18 is connected to the outer side of the wheel seat 7.

[0029] The above structure is similar to a lead screw system. The rotatable threaded rod 17 can be rotated. Since the outer wall of the square rod 18 slides on the inner wall of the square groove 15, the rotation of the threaded rod 17 will drive the square rod 18 to move left and right, which makes it easy to adjust the length of the crossbar 13 and adapt to the different positions of the short side plate 3 and the long side plate 4 in the molding shell 2 (for the production of glass containers of different sizes).

[0030] Working principle: A fixed amount of molten glass is injected into the molding shell 2, which is the container formed by the short side plate 3 and the long side plate 4. The hydraulic system drives the molding cover 1 to move downwards into the container formed by the short side plate 3 and the long side plate 4, and the glass is hydraulically shaped into the shape of the glass container. After cooling, the molding cover 1 is reset. The cylinder 12 drives the crossbar 13 and the support wheel 8 to move downwards. When the support wheel 8 enters the expansion groove 6, the spring 10 will automatically cause the short side plate 3 and the long side plate 4 to flip along the hinge point, so that the inner side of the short side plate 3 and the long side plate 4 are no longer in contact with the outer wall of the glass container, making it easier to remove the glass container.
