Die positioning and adjusting structure for double-bent glass forming machine

Abstract

The invention discloses a die positioning and adjusting structure for a double-bent glass forming machine. The die positioning and adjusting structure comprises a rack, two movable beams, an upper die frame and a lower die frame, wherein the two movable beams are arranged on the left side and the right side of the rack respectively; each movable beam is fixedly provided with at least one longitudinal lead screw. The rack is provided with a plurality of sleeves matched with the lead screws. The sleeves are pushed through a transmission mechanism by means of a drive device and rotate synchronously so as to push the two movable beams to move up and down synchronously. The upper die frame is located below the movable beams. The left side and the right side of the upper die frame are connected with the movable beams through at least one longitudinal first air cylinder. The first air cylinders are used for pushing the upper die frame to move up and down relative to the movable beams. The lower die frame is arranged on the rack in the sliding mode and located below the upper die frame. The lower die frame is connected with the rack through a plurality of longitudinal second air cylinders. The second air cylinders are used for pushing the lower die frame to move up and down relative to the rack. By means of the die positioning and adjusting structure, the height of the upper die frame can be adjusted conveniently and stably, production efficiency can be improved effectively, and the machining quality of glass is guaranteed.

Description

technical field [0001] The invention relates to a glass production equipment, in particular to a double-curved glass forming machine. Background technique [0002] Double-bend glass forming machines are usually used in the glass bending process. The mold bases used to install molds in existing forming machines are usually fixed on the frame, and the height cannot be flexibly adjusted according to the bending angle of the glass. , so a molding machine can only be used to process a small number of glass with different bending angles, which has weak applicability and will have a certain impact on the quality and production efficiency of the glass; some molding machines will detach the mold frame Fixed on the frame, when the height of the formwork needs to be adjusted, the formwork needs to be manually disassembled and re-fixed. Since the formwork is usually large and heavy, this method is not easy to implement, and it is difficult to ensure the level of the formwork, which is l...

[0002] Double-bend glass forming machines are usually used in the glass bending process. The mold bases used to install molds in existing forming machines are usually fixed on the frame, and the height cannot be flexibly adjusted according to the bending angle of the glass. , so a molding machine can only be used to process a few kinds of glass with different bending angles, which has weak applicability and will have a certain impact on the quality and production efficiency of the glass; some molding machines will detach the mold frame Fixed on the frame, when the height of the formwork needs to be adjusted, the formwork needs to be manually disassembled and fixed again. Since the formwork is usually large and heavy, this method is not easy to implement, and it is also difficult to ensure the level of the formwork, which is likely to affect the quality of the glass
