Description

Technical Field

[0001] The present application belongs to the technical field of mold injection molding equipment, and in particular, relates to an upper mold turning mechanism. Background Art

[0002] Moulds are various molds and tools used in industrial production to obtain the required products by methods such as injection molding, blow molding, extrusion, die casting or forging, smelting, stamping, etc. Moulds must be replicated, tested and repaired before they can finally meet the requirements. If problems are found after the trial mold, the mould must be repaired. When repairing the mould, the mould needs to be removed from the injection molding equipment and then installed back for trial mold, and this process is repeated. Since large moulds weigh tons, disassembly and assembly are not only complicated and time-consuming, but also unsafe, which reduces the manufacturing efficiency of the mould and increases the manufacturing cost of the mould. For this reason, a device that can test and repair the mould without disassembling the mould is designed, which is the problem to be solved by this application. Summary of the invention

[0003] In order to overcome the problems existing in the related art, the present application aims to provide an upper mold flipping mechanism, which can flip the upper mold without disassembling the mold to facilitate mold repair, thereby improving the manufacturing efficiency of the mold.

[0004] The present application is implemented through the following technical solutions.

[0005] The technical solution is to provide an upper mold turning mechanism, which is installed on the upper mold plate of the mold trial equipment and can be moved vertically, and is characterized by comprising:

[0039] The first bracket 15 is arranged on the fixed seat 12 for rotation. The first bracket 15 can rotate around the main shaft 1313. The second bracket 16 is arranged at the second end of the main shaft 1313. The second bracket 16 can move with the main shaft 1313 to move away from or close to the first bracket 15. The second bracket 16 can also rotate around the main shaft 1313. The third bracket 17 is connected to the second bracket 16. A workbench 18 is provided on the third bracket 17. The workbench 18 is used to install the upper mold of the mold. The third bracket 17 also slides with the first bracket 15 in the axial direction of the main shaft 1313. The third bracket 17 moves along the axial direction of the main shaft 1313 with the second bracket 16, and slides with the first bracket 15 when moving.

[0040] In order to rotate the first bracket 15 to achieve flipping, a driving component is arranged on the fixed base 12, and the driving component is used to drive the first bracket 15 and the second bracket 16 to rotate around the main axis 1313. The driving component includes a rack 19 arranged on the fixed base 12, two driving gears 20 and a power component 21 arranged on the fixed base 12 for driving the rack 19.

Of course, the telescopic cylinder 14 can also be an independent component.

[0047] The mold flipping mechanism of the present embodiment is installed on the side of the upper mold plate 11. As the upper mold plate 11 is raised and lowered, the upper mold of the mold is directly installed on the workbench 18. During mold trial, the mold flipping mechanism drives the upper mold to be installed on the upper mold plate 11 for injection molding trial production. When the mold needs to be repaired, the mold flipping mechanism drives the upper mold to leave the upper mold plate 11 and flips the upper mold, which is convenient for repairing the upper mold and improves the manufacturing efficiency of the mold.

[0048] The working principle of the mold turning mechanism is that the upper mold of the mold is installed on the workbench 18, and the model cavity of the upper mold faces upward. The driving component drives the first bracket 15 to rotate, and the first bracket 15 drives the third bracket 17, the workbench 18 and the second bracket 16 to turn over until the model cavity of the upper mold faces downward. The workbench 18 is located on the side of the upper template 11. At this time, the telescopic cylinder 14 drives the active movement, and the movement of the main shaft 1313 drives the second bracket 16, the third bracket 17 and the workbench 18 to slide relative to the first bracket 15, thereby pushing the workbench 18 and the upper mold to the bottom of the upper template 11. After fixing the workbench 18, the mold can be tested. After the mold test is completed, if it needs to be repaired, the upper mold is moved out and turned over in the opposite direction to repair the mold.
