Detailed Description

The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. All other embodiments, which can be obtained by a person skilled in the art without making any creative effort based on the embodiments in the present invention, belong to the protection scope of the present invention.

It will be understood that when an element is referred to as being "secured to" another element, it can be directly on the other element or intervening elements may also be present, secured by intervening elements. When a component is referred to as being "connected" to another component, it can be directly connected to the other component or intervening components may also be present. When an element is referred to as being "disposed on" another element, it can be directly disposed on the other element or intervening elements may also be present. The terms "vertical," "horizontal," "left," "right," and the like as used herein are for illustrative purposes only.

Unless defined otherwise, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention belongs. The terminology used in the description of the utility model herein is for the purpose of describing particular embodiments only and is not intended to be limiting of the utility model. As used herein, the term "and/or" includes any and all combinations of one or more of the associated listed items.

Fig. 1 to 2 show a new energy battery case mold according to the present invention, which includes a sheathing board 10, an insert 20, a plurality of joints 30, and two gaskets 40.

The sheathing plate 10 is provided with coupling holes extending from the edge of the sheathing plate 10 to the hollow inside the sheathing plate 10.

The insert 20 comprises a first body 21, a second body 22 and a third body 23. The height of the second body 22 is greater than the height of the first body 21 and the height of the third body 23. The height of the first body 21 is the same as the height of the third body 23. The second body 22 is located between the first body 21 and the third body 23. The first body 21 is provided with a first parting plane 210, the second body 22 with a second parting plane 220 and the third body 23 with a third parting plane 230. Runners are formed in the first and

third parting surfaces

210, 230 and cavities are formed in the second parting surface 220. The first body 21, the second body 22 and the third body 23 are provided with oil passages 50, and oil at a certain temperature is injected into the oil passages 50 to maintain the proper temperature of the cavity and the runner.

The number of the joints 30 is several, and each joint 30 is installed at the end of the coupling hole of the strap 10. The connecting hole is communicated with the warm-die machine through a joint 30.

The number of the spacers 40 is two. In the present embodiment, the shim 40 is a steel sheet.

When assembling the new energy battery shell mold, the first main body 21, the second main body 22 and the third main body 23 are installed in the sleeve plate 10, and mold closing debugging is performed to ensure that the first parting surface 210, the second parting surface 220 and the third parting surface 230 are located on one plane. One shim 40 is then mounted between the first body 21 and the strap 10, and the other shim 40 is mounted between the third body 23 and the strap 10. The first and

third parting surfaces

210, 230 are caused to protrude, i.e. the first and

third parting surfaces

210, 230 are at a greater distance from the deck plate 10 than the second parting surface 220 is from the deck plate 10. Specifically, the thickness of the spacer 40 is determined according to the difference in expansion caused by the difference in height between the second body 22 and the first and

third bodies

21 and 23. In the present embodiment, the thickness of the spacer 40 is 0.15mm, so the first and

third parting surfaces

210 and 230 are 0.15mm higher than the second parting surface 220.

When the new energy battery case mold is used, under high temperature and high pressure, the height of the second body 22 is greater than that of the first body 21 and that of the third body 23, and the heights are different, so that the bodies are expanded differently, but the first and

third division surfaces

210 and 230 are higher than the second division surface 220 by 0.15mm because the first and

third bodies

21 and 23 having low heights are provided with the gasket 40. Therefore, when the die is used under high temperature and high pressure, the first parting surface 210, the second parting surface 220 and the third parting surface 230 are located on the same plane, so that the die surface is flat.

According to the new energy battery shell mold, the thicknesses of the first main body 21 and the third main body 23 are reduced, materials are saved, and the cost is reduced; the distance between the first parting surface 210 and the other surface of the sleeve plate 10 and the distance between the third parting surface 230 and the other surface of the sleeve plate 10 are greater than the distance between the second parting surface 220 and the other surface of the sleeve plate 10, so that the first parting surface 210 corresponding to the first main body 21 and the third parting surface 230 corresponding to the third main body 23 with smaller thickness are protruded, and the phenomenon that the first main body 21, the third main body 23 and the second main body 22 expand differently due to different thicknesses in use is avoided, and the uneven die surface is avoided.

The above examples only show some embodiments of the present invention, and the description thereof is more specific and detailed, but not to be construed as limiting the scope of the utility model. It should be noted that, for those skilled in the art, variations and modifications can be made without departing from the spirit of the utility model, and all equivalent modifications and changes can be made to the above embodiments according to the essential technology of the utility model, which falls into the protection scope of the utility model.
