Abstract
Description
Technical Field
[0001] This utility model relates to the field of glassware processing technology, specifically to a locking structure for glassware forming molds. Background Technology
[0002] Glassware is formed by blowing gas through a forming mold to blow the glass preform into a vessel. Generally, the forming mold is made by joining two molds together. During the blowing process, if the molds are not tightly joined, seam lines may appear at the joint of the molds. To solve this problem, locating pins are used to lock the two molds together. However, during the processing, it is easy for the locating pins to fail to be accurately inserted into the pin holes. Utility Model Content

[0008] Furthermore, a cylinder is installed on the workbench, and a connector is provided on one side of the moving mold. The piston end of the cylinder is connected to the connector through a joint.
[0009] Furthermore, both the fixed mold and the movable mold are provided with locking edges on both sides. The locking edge of the movable mold is machined with a bevel, and the locking edge of the fixed mold is machined with a right-angled surface.
[0010] Furthermore, the locking latch has a chamfer at the right-angled position.
[0011] Compared with the prior art, the locking structure of the glassware forming mold of this utility model has a locking edge and a locking block on the side of the forming mold to lock the mold. Both the locking block and the locking edge are provided with inclined surfaces. The positioning is more convenient through the inclined surface fitting method. Attached Figure Description

Detailed Implementation
[0016] The technical solutions in the embodiments of this utility model will be clearly and completely described below.
[0017] like Figures 1-3 As shown, a glassware forming mold locking structure includes a worktable 1, on which a glassware forming mold is disposed. The glassware forming mold includes a fixed mold 2 and a movable mold 3. The fixed mold 2 is fixed to the worktable 1 on both sides by screws. The worktable 1 is machined with a sliding groove 4. The bottom of the movable mold 3 is machined with a sliding seat. The sliding seat slides in the sliding groove 4. After the movable mold 3 moves into place, it is spliced with the fixed mold 2 to form a glassware forming mold.
[0018] The glassware forming mold has locking edges 5 on both sides, and locking blocks 6 and 7 are respectively provided on the sides of the locking edges 5. Lead screws 8 and 9 are connected to the worktable 1. The two ends of lead screws 8 and 9 are connected to the worktable 1 via lead screw seats. Bearing seats are installed on the lead screw seats, and bearings are installed inside the bearing seats. The two ends of lead screws 8 and 9 are connected to the bearings. Lead screw seats 10 and 21 are respectively provided on lead screws 8 and 9. Lead screw seat 10 and 21 are respectively provided on lead screw 8 and 29. The screw is connected to the lead screw 8 by a right-hand thread, and to the lead screw 9 by a left-hand thread inside the lead screw seat 11. A guide rail 12 is provided between the lead screw 8 and the lead screw 9, and a slider 1 and a slider 2 are connected to the guide rail 12. The locking block 6 is connected to the lead screw seat 10 and the slider 1, and the locking block 7 is connected to the lead screw seat 11 and the slider 2. The locking blocks 6 and 7 have locking slots 13 on their sides, and the locking slots 13 and the locking edge 5 have corresponding bevels 14 that cooperate with each other.
[0019] A motor 15 is installed on the workbench 1. One end of the lead screw 8 and the second lead screw 9 extends out of the lead screw seat and is connected to a pulley. A pulley is also connected to the output shaft of the motor 15. The pulleys are connected to each other by a belt 16. The motor 15 drives the lead screw 8 and the second lead screw 9, which in turn drives the locking block 6 and the second locking block 7 to clamp the locking edges on both sides of the glass forming mold.
[0020] In this embodiment, four glassware forming molds are provided on the workbench 1. Two cylinders 17 are installed on the workbench 1. A connecting block is provided on one side of the moving mold 3. The connecting block is connected to a connecting plate. The piston end of the cylinder 17 is connected to the connecting plate through a connector. The moving mold 3 is pushed by the cylinder 17. The bottom of the moving mold 3 is machined with a dovetail base. The surface of the workbench is machined with a dovetail groove. The dovetail base slides in the dovetail groove. Locking edges are provided on both sides of the fixed mold 2 and the moving mold 3. The locking edge of the moving mold 3 is machined with a bevel 14. The locking edge of the fixed mold 2 is machined with a right angle surface. The locking latch 13 is machined with a chamfer 18 at the position corresponding to the right angle surface. After the moving mold 3 and the fixed mold 2 are closed, the motor 15 drives the lead screw 8 and the lead screw 9. The lead screw 8 and the lead screw 9 drive the locking block 6 and the locking block 7 to move. Through the bevel engagement, the locking latch 13 locks the locking edges on both sides of the moving mold 3 and the fixed mold 2.
