[0002] In the welding of battery cover structural components, the terminal post needs to be placed on the lower mold first, and then the upper mold and lower mold are closed to fix the terminal post before welding. However, as battery cover structural components become more diversified, irregularly shaped terminal posts are prone to horizontal skew during positioning, which can lead to defects such as terminal post damage. Utility Model Content

[0003] The present invention aims to solve at least one of the technical problems existing in the prior art. To this end, the present invention proposes a welding mold with more precise positioning.

[0004] A welding mold according to an embodiment of the present invention includes an upper mold and a lower mold for placing an electrode post. The upper mold includes a mold body and a guide module. The mold body has a guide hole inclined in the vertical direction at one end near the lower mold. The guide module includes a guide post and a limiting structure. The guide post is slidably inserted into the guide hole. The limiting structure is connected to the guide post and the mold body respectively, and is used to prevent the guide post from completely detaching from the guide hole under its own weight. Under the action of external force, the upper mold and the lower mold can approach each other so that the guide post can retract into the guide hole under the push of the lower mold, and push the guide post in the horizontal direction to guide the electrode post on the lower mold.

[0005] A welding mold according to an embodiment of the present utility model has at least the following technical effects: In the use of the welding mold of this application, the electrode post is first placed on the lower mold, and then an external force drives the upper mold to move closer to the lower mold. The guide post, pushed by the lower mold, gradually retracts into the guide hole. Due to the inclined design of the guide hole, the guide post generates a horizontal component force during retraction, thereby pushing and guiding the electrode post on the lower mold to achieve more precise positioning. After the upper and lower molds are fully closed, the electrode post is stably fixed, and subsequent welding operations can be performed. From the above usage process, it can be seen that this application, through the cooperation of the mold body and the guide module, can accurately position irregularly shaped electrode posts, effectively avoiding damage or poor welding caused by horizontal tilting of the electrode post, thus improving welding accuracy and yield.

[0022] The following is for reference. Figures 1 to 3 A welding mold according to an embodiment of the present utility model will be described in detail.

[0023] refer to Figures 1 to 3 According to an embodiment of the present invention, a welding mold includes an upper mold 100 and a lower mold for placing an electrode post. The upper mold 100 includes a mold body 110 and a guide module 120. The mold body 110 is provided with a guide hole 110a inclined in the vertical direction at one end near the lower mold. The guide module 120 includes a guide post 121 and a limiting structure. The guide post 121 is slidably inserted into the guide hole 110a. The limiting structure is connected to the guide post 121 and the mold body 110 respectively, and is used to prevent the guide post 121 from completely detaching from the guide hole 110a under its own weight. Under the action of external force, the upper mold 100 and the lower mold can approach each other so that the guide post 121 can retract into the guide hole 110a under the push of the lower mold, and the guide post 121 pushes and guides the electrode post on the lower mold in the horizontal direction.

[0024] In the use of the welding mold of this application, the electrode post is first placed on the lower mold, and then the upper mold 100 is driven by external force to move closer to the lower mold. Under the push of the lower mold, the guide post 121 gradually retracts into the guide hole 110a. Because the guide hole 110a is inclined, the guide post 121 will generate a component force in the horizontal direction during the retraction process, thereby pushing and guiding the electrode post on the lower mold to make its position more accurate. When the upper mold 100 and the lower mold are completely closed, the electrode post is stably fixed and subsequent welding operations can be performed. From the above usage process, it can be seen that this application, through the cooperation of the mold body 110 and the guide module 120, can accurately position irregularly shaped electrode posts, effectively avoiding damage or poor welding caused by horizontal tilting of the electrode post, and improving welding accuracy and yield.

[0025] refer to Figures 1 to 3 In some embodiments of this utility model, a mounting groove 110b is provided on the side wall of the guide hole 110a, and a ball bearing 130 is provided in the mounting groove 110b for rolling, and the guide post 121 abuts against the surface of the ball bearing 130. It is understandable that by opening a mounting groove 110b on the side wall of the guide hole 110a and setting a rolling ball 130 in the mounting groove 110b, the guide post 121 abuts against the surface of the ball 130. Thus, during the sliding process of the guide post 121 along the guide hole 110a, the friction generated between the guide post 121 and the ball 130 is rolling friction. The resistance encountered by the guide post 121 during the sliding process in the guide hole 110a can be reduced, thereby making the movement of the guide post 121 in the guide hole 110a smoother. At the same time, the setting of the ball 130 makes the contact area between the guide post 121 and the hole wall of the guide hole 110a smaller, thereby reducing the wear between the guide post 121 and the guide hole 110a and extending the service life of the mold.

[0026] like Figure 2 and Figure 3 As shown, in some embodiments, the extending direction of the mounting groove 110b is parallel to the extending direction of the guide hole 110a, and a plurality of balls 130 are spaced apart within the mounting groove 110b along its own extending direction. It is understood that further defining the extending direction of the mounting groove 110b as parallel to the extending direction of the guide hole 110a, and spaced apart within the mounting groove 110b with the balls 130 evenly distributed, ensures that the guide post 121 remains in contact with the balls 130 during sliding, further reducing the frictional resistance experienced by the guide post 121 during sliding and improving the smoothness and guiding accuracy of the guide post 121's movement.

[0027] It should be noted that, since the guide hole 110a is inclined in the vertical direction, the pressure between the guide post 121 and the lower hole sidewall of the guide hole 110a will be greater under its own weight, resulting in greater frictional resistance between the guide post 121 and the lower hole sidewall of the guide hole 110a.

[0028] For the reasons mentioned above, such as Figure 2 and Figure 3 As shown, in some embodiments, the lower sidewall of the guide hole 110a is provided with a mounting groove 110b. It is understood that, because the lower sidewall of the guide hole 110a is provided with a mounting groove 110b, and a plurality of ball bearings 130 are disposed within the mounting groove 110b, when the guide post 121 retracts upward under the push of the lower mold, the ball bearings 130 on the lower sidewall can effectively support the sliding of the guide post 121, reducing the friction between the guide post 121 and the lower sidewall of the guide hole 110a, and improving the smoothness of the guide post 121's sliding process.

[0029] like Figure 2 and Figure 3 As shown, in some embodiments, the upper sidewall of the guide hole 110a is provided with a mounting groove 110b. It is understood that by also providing a mounting groove 110b and ball bearings 130 on the upper sidewall of the guide hole 110a, a double-sided ball bearing 130 structure is formed on the upper and lower sidewalls of the guide hole 110a. This allows both the upper and lower sidewalls of the guide post 121 to receive rolling support during its sliding motion along the guide hole 110a, further reducing the friction experienced by the guide post 121 during sliding and ensuring more stable and precise movement of the guide post 121.

[0030] refer to Figure 2 and Figure 3 In some embodiments of this utility model, the ball bearing 130 is a round ball. It is understood that the round ball bearing 130 is relatively simple, easy to process and install, and has excellent rolling performance, which can meet the requirements of efficient sliding of the guide post 121.

[0031] refer to Figure 2 and Figure 3 In some embodiments of this utility model, the limiting structure includes an elastic connector, which is connected to the guide post 121 and the mold body 110 respectively. It is understood that by connecting the elastic connector to the guide post 121 and the mold body 110 respectively, when the upper mold 100 separates from the lower mold, the elastic force provided by the elastic connector can prevent the guide post 121 from completely disengaging from the guide hole 110a under gravity. Furthermore, when the upper mold 100 and the lower mold are closed, the elastic force provided by the elastic connector can ensure that the guide post 121 is smoothly and horizontally guided to the pole post.

[0032] like Figure 2 and Figure 3 As shown, in some embodiments, an elastic connector is disposed between the guide post 121 and the bottom of the guide hole 110a. One end of the elastic connector is connected to the bottom of the guide hole 110a, and the other end is connected to the upper end of the guide post 121. It can be understood that the elastic connector, located between the guide post 121 and the bottom of the guide hole 110a, with one end connected to the bottom and the other end connected to the upper end of the guide post 121, fully utilizes the internal space of the guide hole 110a, making the structure more compact. Furthermore, the elastic force direction of the elastic connector is consistent with the movement direction of the guide post 121, ensuring that the guide post 121 can stably reset.

[0033] like Figure 2 and Figure 3 As shown, in one embodiment, the upper end of the guide post 121 is provided with a T-shaped hook 121a, and one end of the elastic connector is engaged with the hook 121a. It can be understood that by engaging the elastic connector with the T-shaped hook 121a, the installation and fixation of the elastic connector are facilitated, while preventing the elastic connector from falling off during repeated stretching, thus improving the durability of the guide module 120.

[0034] refer to Figures 1 to 3 In some embodiments of this utility model, the mold body 110 is provided with two guide holes 110a symmetrically distributed in the horizontal direction, and the horizontal distance between the two guide holes 110a gradually increases from top to bottom. Each guide hole 110a corresponds to a guiding module 120. It can be understood that by providing two horizontally symmetrically distributed guide holes 110a on the mold body 110, and the horizontal distance between the two guide holes 110a gradually increases from top to bottom, and each guide hole 110a corresponds to a guiding module 120, the design of the double guiding post 121 can simultaneously apply horizontal thrust to both sides of the pole post, ensuring that the pole post is uniformly guided in the horizontal direction and avoiding skewing caused by unilateral force.

[0035] Although embodiments of the present invention have been shown and described, those skilled in the art will understand that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the claims and their equivalents.
