AI Technical Summary
Technical Problem
In existing glass bottle production molds, after the upper mold base and lower mold base are disconnected, the formed glass bottle remains tightly connected inside the lower mold base and is difficult to remove.
Method used
By using a combination of fixed and movable molds, and with the support of the mold base and protrusions, glass bottles are formed inside the mold cavity. The design of the protrusions and the mold base releases the restriction on the glass bottle during demolding. The tilting and unloading of the glass bottle are achieved with the help of hydraulic push rods and linkages.
Benefits of technology
This allows for easy removal of glass bottles, simplifies the demolding process, and improves production efficiency.

Abstract
The application provides an improved mold for producing medium borosilicate glass bottles, and relates to the technical field of glass bottle production and processing. The mold comprises a fixed mold, movable molds, support mold seats and a mold stripping assembly. Two movable molds and the fixed mold cooperatively form two mold cavities. The top of one side of each of the two support mold seats is provided with two protrusions. The mold stripping assembly comprises a hydraulic push rod, the inside of one end of the hydraulic push rod is provided with a guide sliding sleeve, one end of the guide sliding sleeve is provided with an adapter seat plate, a pulling spring is fixed between one side of the adapter seat plate and the movable end, and one end of the hydraulic push rod is provided with a linkage. The technical key points are as follows: the glass bottle is formed in the mold cavity between the fixed mold and the movable mold, the concave part of the bottom of the glass bottle is formed by the protrusions, and the horizontal surface of the bottom of the glass bottle is formed by the surface of the support mold seat. When the movable mold is controlled to move away from the fixed mold, the restriction on the glass bottle is removed, and the glass bottle is conveniently taken out.
