Description

Technical Field

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

[0002] The main raw materials for glass bottles include quartz sand, soda ash (sodium carbonate), limestone, and feldspar. These raw materials need to be crushed, washed, dried, and iron removed to ensure purity. Quartz sand, as the core component, provides the skeletal structure of the glass, while soda ash and limestone adjust the chemical stability and heat resistance of the glass.

[0003] In the existing glass bottle manufacturing process, molding dies are required. The bottom mold of the molding die can be raised and lowered using a lifting device. The bottom mold is essentially a ventilation duct, and the lifting of this duct is adjusted by a cylinder, resulting in poor adjustment precision and affecting the performance. Therefore, we propose a lifting cylinder adjustment component for the bottom mold lifting device of a molding machine. Utility Model Content

[0006] By adopting the above technical solution, when it is necessary to adjust the height of the lifting duct, the large gear is rotated to drive the small gear to rotate, which in turn drives the lifting adjustment rod to rotate. Under the screw drive, the lifting duct can be adjusted to move up and down with high precision, which helps to improve the accuracy of adjustment.

[0007] In a preferred embodiment of this utility model, the lifting air duct has a hollow structure on both sides, and an airflow channel is provided on the upper side of the middle of the lifting air duct.

[0008] By adopting the above technical solution, the airflow channel is designed so that when connected to the mold, the airflow channel can be used to guide the gas, thereby enabling the gas to be used for cooling.

[0009] In a preferred embodiment of this utility model, the tail end of the lifting adjustment rod is fixedly connected to a second end shaft, and the second end shaft is rotatably connected to the bottom of the inner cavity of the housing.

[0010] By adopting the above technical solution, the setting of the second end shaft enables the lifting adjustment rod to be stably rotatably connected to the bottom of the inner cavity of the housing.

[0011] In a preferred embodiment of this utility model, a sealing plate is fixedly installed on one side wall of the housing.

[0012] By adopting the above technical solution, the sealing plate can block one side of the shell.

[0013] In a preferred embodiment of this utility model, an upper clamping plate is fixedly connected to the top of the lifting air duct, and a lower clamping plate is fixedly connected to the outer wall of the lifting air duct.

[0014] By adopting the above technical solution, the upper and lower clamping plates enable the lifting air duct to be clamped to the turntable, thereby achieving a stable connection.

[0015] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0016] The technical solution of this application provides a lifting cylinder adjustment component for a molding machine bottom mold lifting device. The large gear drives the small gear to rotate, which in turn drives the lifting adjustment rod to rotate. This, in turn, drives the lifting air cylinder to rise and fall under the threaded drive. The threaded adjustment improves the accuracy of the adjustment and makes the adjustment operation convenient and quick. Attached Figure Description
