Description

Technical Field

[0001] The utility model relates to the technical field of vertical injection molding machines, in particular to a mounting mold sliding structure for vertical injection molding machines. Background Art

[0002] At present, injection molding machines are generally divided into vertical injection molding machines and horizontal injection molding machines. In one cycle, a certain amount of plastic can be heated and plasticized within a specified time, and then the molten plastic is injected into the mold cavity through a screw at a certain pressure and speed. During the use of the vertical injection molding machine, it is necessary to install and replace injection molds of different sizes according to the production of different products. However, the workbench of the existing vertical injection molding machine has no sliding mechanism. During the replacement of the injection mold, the injection mold needs to be placed on the workbench of the vertical injection mold and pushed to the position of the positioning mold. During the pushing process, the bottom of the injection mold and the workbench produce friction, which affects the service life of the mold or causes damage to the workbench. Especially when replacing a relatively large injection mold, it is time-consuming and laborious to manually push the mold due to the large friction with the work. Two or more people are required to move the mold each time the mold is mounted, and it is difficult to accurately position the mold at the mold installation position, which affects the quality of the injection molded product and the work efficiency, and increases the defective rate. Therefore, we redesigned a sliding structure for installing the mold for a vertical injection molding machine. Utility Model Content
