Description

Technical Field

[0001] The utility model relates to the technical field of flow channel plate stamping dies, in particular to a flow channel plate fine punching die. Background Art

[0002] The liquid cooling plate is one of the most critical components in the battery pack liquid cooling system. The coolant flowing through the internal flow channel of the liquid cooling plate can take away the excess heat generated by the battery or module during operation, thereby achieving the heat dissipation effect of the battery.

[0003] During the processing of the liquid cooling plate, it is necessary to perform punching operations through a stamping die to facilitate the subsequent processing of the water cooling plate. In the prior art, after the hard mold punching process and the soft mold laser cutting, there is a positional error between the flow channel and the contour and the hole position, which leads to poor matching in the later stage. Utility Model Content

[0004] The utility model aims to provide a flow channel plate fine punching die to solve the problems raised in the above background technology.

[0005] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a runner plate fine punching die, characterized in that it includes an upper die, a lower die and a lower die forming block arranged therebetween, the upper die being provided with a cylinder, a support block, a connecting head, a fixing block, a guide block and a punch in sequence from top to bottom, and the lower part of the punch being provided with a material pressing skylight and an upper die forming block in sequence.

[0006] Further optimized, the cylinder is a double-stroke cylinder, and the support block is arranged at the lower part of the cylinder, and the telescopic end of the cylinder passes through the support block and is connected to the connecting head.

[0007] For further optimization, the fixing block is arranged on the outside of the connecting head.

[0008] For further optimization, the other end of the connecting head away from the supporting block is provided with a punch connected thereto.

[0009] Further optimized, the guide block is sleeved on the punch.

[0010] For further optimization, the end surface of the lower die forming block is provided with a die sleeve.

[0011] Further optimized, the pressing skylight is arranged in the upper mold forming block.

[0012] Beneficial Effects

[0013] The flow channel plate fine punching die provided by the utility model is fixed on the upper and lower die forming blocks to ensure that the flow channel is completely formed. When there is no material flow, the punching action is completed by the cylinder. The punching effect is consistent with the blanking effect of the conventional punching die. In the post-process working conditions, the fine punching can be used as a positioning function to meet the various position requirements of the cold plate. BRIEF DESCRIPTION OF THE DRAWINGS

[0017] The following are specific embodiments of the present invention and the accompanying drawings to further describe the technical solution of the present invention, but the present invention is not limited to these embodiments.

[0018] Example

[0019] like Figure 1-2 As shown, a runner plate fine punching die comprises an upper die 12, a lower die 13 and a lower die forming block 11 arranged therebetween, a cylinder 2, a support block 3, a connector 4, a fixing block 5, a guide block 6 and a punch 7 are arranged in the upper die 12 from top to bottom, and a material pressing skylight 8 and an upper die forming block 9 are arranged in the lower part of the punch 7 in sequence.

[0020] In this embodiment, the cylinder 2 is a double-stroke cylinder, and the support block 3 is arranged at the lower part of the cylinder 2. The telescopic end of the cylinder 2 passes through the support block 3 and is connected to the connecting head 4. The support block 3 plays the role of supporting 2 to ensure that the position of the cylinder 2 in the upper mold 12 does not deviate or shake.

[0021] The fixing block 5 is arranged outside the connector 4, and is used to fix the connector 4 and the punch 7 to be tightly connected, so as to avoid the problem of the punch 7 and the connector 4 being broken during punching.

[0022] The other end of the connecting head 4 away from the supporting block 3 is provided with a punch 7 connected thereto.

[0023] The guide block 6 is mounted on the punch 7. The setting of the guide block 6 ensures the accuracy of the stroke of the punch 7 and avoids the error of the impact position, which leads to the deviation of the punching position.

[0024] The end surface of the lower mold forming block 11 is provided with a die sleeve 10 .

[0025] The pressing skylight 8 is arranged in the upper mold forming block 9 .

[0026] Finally, it should be noted that the above description is only a preferred embodiment of the utility model and is not intended to limit the utility model. Although the utility model is described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions recorded in the aforementioned embodiments or replace some of the technical features therein by equivalents. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the utility model shall be included in the utility model content within the protection scope of the utility model.
