Description

Technical Field

[0001] The utility model relates to the technical field of welding moulds, in particular to a battery temperature switch welding mould. Background Art

[0002] The battery temperature switch is a temperature switch that uses a bimetallic strip as a temperature sensing element. When the battery is working normally, the bimetallic strip is in a free state and the contacts are in a closed / open state. When the temperature rises to the operating temperature value, the bimetallic element is heated to generate internal stress and quickly operates, opening / closing the contacts and cutting off / connecting the circuit, thereby playing a thermal protection role. When the temperature drops to the reset temperature, the contacts automatically close / open and resume normal working state. In the production process of the battery temperature switch, multiple metal sheets need to be placed in a welding mold for laser welding.

[0003] After welding is completed, the battery temperature switch welding mold in the prior art is generally used to remove the metal sheet in the mold by hand buckle, inverted buckle or with the help of other tools. The operation is cumbersome and inconvenient, and it is difficult to quickly remove the metal sheet in the mold, which affects the production efficiency of the battery temperature switch.

[0013] Furthermore, a connecting plate slidably connected to the inner wall of the mounting groove is commonly fixed to the bottom of the multiple sliding plates, a mounting plate is fixed to the inner wall of the mounting groove, a plurality of second springs are fixed to the upper surface of the mounting plate, and the upper ends of the plurality of second springs are all fixed to the bottom of the connecting plate.

[0014] By adopting the above technical solution, the sliding plate keeps the top plate in the receiving groove under the elastic force of the second spring, thereby reducing the probability of the top plate escaping upward from the receiving groove.

[0015] Furthermore, a stepped groove is provided at the intersection between the inner wall of the installation groove and the bottom of the mold body, and a cover plate is fixed in the stepped groove by screws.

[0016] By adopting the above technical solution, the cover plate closes the notch of the installation groove, thereby protecting the components in the installation groove and reducing the probability of damage to the components in the installation groove.

[0017] Furthermore, two symmetrically arranged positioning holes are formed through the upper surface of the mold body.

[0018] By adopting the above technical solution, the positioning holes are provided, so that when the welding device performs laser welding, it aligns with the metal sheet through the positioning holes, which is beneficial to accurately weld the metal sheet.

[0019] In summary, the utility model has the following beneficial effects:

[0020] 1. In this application, the metal sheet is placed in the mold groove and welded by the laser welding device. After welding, the worker squeezes the yielding part through the driving component to drive the sliding plate to move upward, so that the sliding plate drives the top plate to move upward to lift the welded metal sheet, which is convenient for quickly taking out the metal sheet in the mold and improves the production efficiency of the battery temperature switch;

[0021] 2. In this application, when it is necessary to drive the sliding plate to move upward, the worker presses the pressing block inward, so that the cross bar drives the extrusion block to move towards the sliding plate, and the extrusion block abuts against the yielding part, so that the sliding plate moves upward, and then the top plate moves upward to lift the metal sheet;

[0022] 3. In this application, after the top plate is pushed out upward by pressing the pressing block inward, the pressing block rebounds under the elastic force of the first spring after the pressing block is released, so that the extrusion block is separated from the contact with the sliding plate, so that the top plate returns to the receiving groove, which is convenient for continuing to use the welding mold to weld the metal sheet.
