Detailed Description

The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative work belong to the protection scope of the present invention.

Referring to fig. 1, in an embodiment of the present invention, a processing apparatus for a liquid cooling plate of a power battery includes a base 1; a forming mold core 2 fixed on the base through a detachable fixing device; the limiting seal plate 3 can be in sealing connection with the forming mold core 2, a groove 31 is formed in one side, connected with the forming mold core 2, of the limiting seal plate, and a blowing air inlet pipe 32 communicated with the groove 31 is arranged on the side face, not provided with the groove 31, of the limiting seal plate 3.

Specifically, referring to fig. 1, 4 and 5, the base 1 is fixedly connected to the forming mold core 2 through a detachable fixing device, the detachable fixing device includes a first fixing device 11 and a second fixing device 12, the first fixing device 11 is a through hole disposed at the same position at four corners of the base 1 and the forming mold core 2, and a bolt disposed in the through hole; second fixing device 12 is for evenly setting up the round hole in the middle of base 1, and set up the screw in the round hole, first fixing device 11 and second fixing device 12 are fixed base 1 and shaping mold core 2 jointly, make and form detachable fixed connection structure between base 1 and the shaping mold core 2, and base 1 that the runner forming process of runner plate used can share, has reduced the mould cost.

Specifically, referring to fig. 4, a forming groove 21 is formed in one side of the forming mold core 2 connected to the limiting sealing plate 3, and what forming groove 21 is specifically used by the forming mold core 2 can be selected as required, so that the production requirements of customers for multiple varieties and small batches are met.

Specifically, referring to fig. 1-3, the limiting sealing plate 3 is provided with the inflation inlet tube 32, one end of the inflation inlet tube 32, which is communicated with the inner wall of the groove 31, is located at the same horizontal plane with the inner wall of the groove 31, an unformed flow channel plate is placed in the groove of the limiting sealing plate 3, the limiting sealing plate 3 is pressed on the forming mold core 2, and the sealing performance is ensured, because an unformed flow channel plate needs to be placed between the forming mold core 2 and the limiting sealing plate 3, the plate can be firmly attached to the mold core to complete sealing by applying appropriate pressure to the limiting sealing plate 3, the extrusion deformation of the periphery of the plate is not a problem, since laser trimming is required later, the completion of forming of the middle part of the plate is only required, if necessary, a sealing ring can be additionally arranged, and then high-pressure gas is filled through the inflation inlet tube 32, so that the unformed runner plate is subjected to extension forming along the forming mold core.
