AI Technical Summary
In the secondary molding process of existing glass bottle forming molds, the die opening is prone to offset errors, causing the primary blank to be out of the center of the forming mold position, which affects the molding quality.
The design employs a left and right half-mold, with left and right correction blocks respectively installed on the left and right half-molds. During mold closing, these correction blocks are used to push and fine-tune the die, ensuring accurate die positioning and forming the bottle mold cavity.
It achieves precise positioning of the die, improves the molding accuracy and quality of glass bottles, avoids skewing and scraping of the primary preform during the molding process, and enhances the molding quality.

Abstract
Claims
1. A glass bottle forming mold comprising a left half mold (21) and a right half mold (22) which cooperates with the left half mold (21), characterized in that, Two left straightening blocks (4) are provided on the top of the left half mold (21) near the edge of the right half mold (22). The two left straightening blocks (4) are arranged opposite each other along the radial direction of the left half mold (21). Two right straightening blocks (5) are provided on the top of the right half mold (22) near the edge of the left half mold (21). The two right straightening blocks (5) are also arranged opposite each other along the radial direction of the right half mold (22). In the mold-closed state, the left half mold (21) and the right half mold (22) form a bottle mold cavity. The inner circle formed by the two left straightening blocks (4) and the two right straightening blocks (5) is close to each other and cooperates to form the same diameter as the outer edge diameter of the corresponding position of the die (31). The center of the inner circle and the center of the molding structure are located on the same vertical line.
2. The glass bottle forming mold of claim 1, wherein, The upper surfaces of the left half mold (21) and the right half mold (22) are detachably provided with connecting plates (6) on their adjacent edges. The two left correction blocks (4) or the two right correction blocks (5) are arranged opposite each other on both sides of the upper surface of the corresponding connecting plates (6).
3. The glass bottle forming mold of claim 2, wherein, The connecting plate (6) is arranged in a semi-circular shape, and the top surface of the left half mold (21) or the right half mold (22) is provided with an embedding groove (7) that cooperates with the connecting plate (6).
4. The glass bottle forming mold of claim 3, wherein, At least one fastening bolt (8) is provided on the connecting plate (6). The main body of the fastening bolt (8) passes through the connecting plate (6) and is threaded into the embedded groove (7). The end of the fastening bolt (8) is embedded in the connecting plate (6).
5. A glass bottle forming mold according to claim 3 or 4, characterized in that, The bottom end face of the connecting plate (6) is provided with a positioning post (9), and the bottom of the embedding groove (7) is provided with a positioning groove (10) that cooperates with the positioning post (9).
6. The glass bottle forming mold of claim 1, wherein, The two left correction blocks (4) or the two right correction blocks (5) are provided with a clearance inclined surface (12) on their opposite sides.
