Description

Technical Field

[0001] This utility model relates to the field of damper cylinder technology, specifically a damper cylinder assembly for a molding machine bottom mold lifting device. Background Technology

[0002] During the production and processing of glass bottles, a corresponding glass bottle forming machine is required. The forming mold in the glass bottle forming machine includes a lifting device, which is also equipped with an air volume adjustment component. This component can adjust the air volume during cooling and seal the air inlet when cooling is not required.

[0003] Currently, when sealing air inlets, the sealing is often achieved by ensuring the damper adjustment plate and the air inlet are completely fitted together. However, the clamping force between the damper adjustment plate and the air inlet is limited, resulting in poor sealing effect. Therefore, we propose a damper cylinder assembly for the bottom mold lifting device of a molding machine. Utility Model Content

[0004] The purpose of this utility model is to provide a damper cylinder assembly for a bottom mold lifting device of a molding machine, which solves the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a damper cylinder assembly for a bottom mold lifting device of a molding machine, comprising a top plate, a cylinder body fixedly connected to the bottom of the top plate, a piston disposed in the inner cavity of the cylinder body, a copper sleeve detachably fixedly connected to the tail end of the cylinder body, a piston rod fixedly connected to the bottom of the piston, a damper cover plate connected to the tail end of the piston rod, an air inlet and an air outlet respectively opened on the top of the top plate corresponding to the two sides of the cylinder body, a spring fitted on the outer wall of the piston rod, and the two ends of the spring being fixedly connected to the copper sleeve and the damper cover plate respectively.

[0006] By adopting the above technical solution, in actual use, both the air inlet and outlet are connected to the air pipe, and the air pipe is equipped with a suitable control valve. When it is necessary to block the air inlet, the gas in the cylinder is discharged, so that the spring can push the damper cover to drop, thereby blocking the air inlet and improving the fit during blocking, which in turn helps to improve the blocking effect. When it is necessary to open the air inlet for air intake, gas is introduced into the cylinder through the air inlet, so that the gas will push the piston to rise, thereby driving the damper cover to rise and thus releasing the air inlet.

[0007] In a preferred embodiment of this utility model, a connecting column is fixedly connected to the tail end of the piston rod. The outer wall of the connecting column is provided with external threads. A threaded hole is provided at the top center of the damper cover. The connecting column is inserted into the threaded hole and the external threads and the threaded hole are engaged.

[0008] By adopting the above technical solution, the damper cover can be detachably connected to the connecting column through the engagement of the external thread and the threaded hole, thus making it easy to disassemble the damper cover for maintenance and replacement.

[0009] In a preferred embodiment of this utility model, a connecting hole is provided on one side of the top of the top plate.

[0010] By adopting the above technical solution, the connection hole design makes it easy to connect and fix the top plate to the shell.

[0011] In a preferred embodiment of this utility model, a suitable rubber pad is fixedly glued to the bottom of the damper cover.

[0012] By adopting the above technical solution, the rubber pad can further improve the fit when pressed onto the cover plate.

[0013] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0014] The technical solution of this application provides a bottom mold lifting device air door cylinder assembly for a molding machine. By lowering the air door cover plate with a spring without introducing gas, the sealing can be achieved, which helps to improve the tightness of the pressing and thus improve the sealing effect.

[0015] By introducing gas, the piston can be lifted, which in turn lifts the damper cover, thus facilitating the rapid release of air from the inlet. Attached Figure Description

[0023] Please see Figure 1-3 This utility model provides a technical solution: a damper cylinder assembly for a bottom mold lifting device of a molding machine, including a top plate 1, a cylinder body 11 fixedly connected to the bottom of the top plate 1, a piston 12 disposed in the inner cavity of the cylinder body 11, a copper sleeve 13 detachably fixedly connected to the tail end of the cylinder body 11, a piston rod 14 fixedly connected to the bottom of the piston 12, a damper cover plate 15 connected to the tail end of the piston rod 14, an air inlet 17 and an air outlet 18 respectively opened on the top of the top plate 1 corresponding to the two sides of the cylinder body 11, a spring 16 fitted on the outer wall of the piston rod 14, and the two ends of the spring 16 fixedly connected to the copper sleeve 13 and the damper cover plate 15 respectively.

[0024] It should be understood that in actual use, both the air inlet 17 and the air outlet 18 are connected to the air pipe, and the air pipe is equipped with a suitable control valve. When it is necessary to block the air inlet, the gas in the cylinder 11 is vented, so that the spring 16 can push the damper cover 15 down, thereby blocking the air inlet and improving the fit during blocking, which in turn helps to improve the blocking effect. When it is necessary to open the air inlet for air intake, gas is introduced into the cylinder 11 through the air inlet 17, so that the gas will push the piston 12 to rise, thereby driving the damper cover 15 to rise, thereby releasing the air inlet.

[0025] Furthermore, a suitable rubber pad is glued to the bottom of the damper cover 15. The rubber pad enhances the fit when pressed onto the cover.

[0026] Furthermore, a connection hole 19 is provided on one side of the top of the top plate 1. The connection hole 19 makes it easy to connect and fix the top plate 1 to the shell.

[0027] like Figure 1 and 2 As shown in Figure 3, a connecting column 2 is fixedly connected to the tail end of the piston rod 14. The outer wall of the connecting column 2 is provided with an external thread 21. A threaded hole is provided at the top center of the damper cover plate 15. The connecting column 2 is inserted into the threaded hole and the external thread 21 and the threaded hole are engaged.

[0028] It should be understood that the external thread 21 and the threaded hole engage, thereby enabling the damper cover 15 to be detachably connected to the connecting column 2, thus making it easy to disassemble the damper cover 15 for maintenance and replacement.

[0029] Furthermore, in this document, relational terms such as "first" and "second" are used merely to distinguish one entity or operation from another, and do not necessarily require or imply any such actual relationship or order between these entities or operations. Moreover, the terms "comprising," "including," or any other variations thereof are intended to cover non-exclusive inclusion, such that a process, method, article, or apparatus that comprises a list of elements includes not only those elements but also other elements not expressly listed, or elements inherent to such process, method, article, or apparatus.
