A battery-based heat-sealing mold for shell cover

Abstract

The invention discloses a battery-based shell cover heat-sealing mold, which includes an upper mold, a lower mold is installed on one side of the upper mold, a U-shaped support seat is installed inside the lower mold through a clamping seat, and the bottom of the upper mold is installed. Partition plates are installed on both sides of the end, a guide plate is installed on one side of the partition plate, a positioning rod is evenly installed at the bottom end of the guide plate, and an impurity removal plate is installed at the top of the guide plate. The structure of the invention is scientific and reasonable. Safe and convenient, equipped with a card seat and a U-shaped support seat, the lower mold can support and fix the lower part of the battery shell of different sizes, and the scope of application of the lower mold is expanded. The guide plate and positioning rod are provided to ensure that the upper mold is falling. The accuracy of positioning between the time and the lower mold ensures the heat sealing quality of the battery shell cover, and the impurity removal plate is provided to avoid the accumulation of waste materials in the upper mold, which affects the tightness of the connection between the upper mold and the lower mold during heat sealing. sex.

Description

technical field [0001] The invention relates to the technical field of shell cover heat-sealing mold devices, in particular to a battery-based shell cover heat-sealing mold. Background technique [0002] In the automotive lead-acid battery industry, battery sealing is one of the important processes in the manufacturing process. In the battery packaging process, the sealing of the battery cover and the battery case is to use heating to melt the sealing surface of the battery case and battery cover first. Then the battery cover is in contact with the battery case, and the case cover is bonded together under a certain pressure to form a seal. The sealing of the case cover is carried out by a fully automatic heat-sealing machine, which also needs to use a heat-sealing mold, a heat-sealing mold The quality of the structure greatly affects the quality of the battery cover. In the prior art, there have been a lot of disclosures about the structure of the heat-sealing mold for the b...

Problems solved by technology

[0003] The present invention provides a shell cover heat-sealing mold based on batteries, which can effectively solve the problem that the existing shell cover heat-sealing molds proposed in the above background technology cannot realize the support and fixation of the lower part of battery shells of different sizes by the lower mold during use. , the scope of application of the lower mold is small and the positioning accuracy between the upper mold and the lower mold is poor when it falls, and the upper mold is prone to slip when extruding, which affects the heat sealing quality of the battery case cover
