Description

Technical Field

[0001] The utility model relates to the field of battery tray molds, in particular to an electric vehicle battery tray mold. Background Art

[0002] During the processing of battery tray molds, when simultaneously filling each cavity of a multi-cavity injection mold, pouring defects are likely to occur, and the molten plastic flows unevenly into each cavity.

[0003] To solve the above problems, the Chinese utility model with the patent number CN207711266U in the prior art discloses an electric vehicle battery tray mold, which relates to the technical field of automotive parts molds, including an upper template and a lower template. The upper template and the lower template are vertically movably connected through positioning columns. The lower template is provided with a first main cavity, a second main cavity, and a main runner. The upper template is provided with a flow rate adjusting device. The flow rate adjusting device includes a screw sleeve fixed on the upper template. The screw sleeve is perpendicular to the lower template. An adjusting screw is movably arranged in the screw sleeve. The adjusting screw passes through the screw sleeve. A first runner hole and a second runner hole are sequentially arranged from top to bottom at one end of the adjusting screw. A circular sub-runner is arranged on the sub-runner. A first indicating rod and a second indicating rod are also arranged at the other end of the adjusting screw. The utility model has the advantages that when pouring with multiple cavities in one mold, the flow balance is ensured, so that each cavity is filled simultaneously, avoiding the generation of pouring defects, and the flow rate of the molten plastic can be adjusted.

[0004] However, there are still problems in the above technology during use. When rotating the adjusting screw to change the corresponding runner hole, it is necessary to operate the corresponding adjusting screw separately, which makes the operation troublesome. Moreover, when the adjusting screw is threadedly connected in the screw sleeve and the adjusting screw is rotated to change the corresponding runner hole, the adjusting screw will also move up and down. This makes a gap exist between the bottom of the adjusting screw and the bottom of the groove of the lower template, and the molten plastic flows into the cavity from this gap, affecting the function of adjusting the flow rate of the molten plastic. Therefore, optimization and improvement are needed. Summary of the Utility Model
