Abstract
Description
Technical Field
[0001] The utility model relates to a mould structure, in particular to an upper and lower mould structure of an aluminium shell blister tray. Background Art
[0002] The outer layer of the single cell of the power battery is equipped with a protective shell, which can be cylindrical or square. The square one has a higher market share. The assembly of the square aluminum shell and the cell is completed by transfer using a blister tray. The blister tray is made of ABS+TPU material with good flexibility. However, since the tray base material itself is relatively thin, with a thickness of only 2mm, and the aluminum shell is relatively high, after blister forming and stretching, the characteristic position in the limit groove of the aluminum shell is easily deformed and damaged. Therefore, an upper and lower mold matching structure is designed to assist in blister forming. Utility Model Content
[0003] Aiming at the problems of preventing the internal structure of the limiting groove from being deformed and unevenly formed in the prior art, the utility model aims to provide an upper and lower mold structure of an aluminum shell blister tray.
[0004] In order to achieve the above-mentioned purpose, the utility model is realized through the following technical scheme: an upper and lower mold structure of an aluminum shell blister tray, including an upper mold and a lower mold, a vacuum circular hole with a diameter of 4 mm is arranged at the bottom of the lower mold, the distance from the circular hole to the characteristic surface is 1.5 mm, a pinhole is opened in the center of the circular hole, the outer shell of the upper mold is surrounded by a 1 mm thick iron sheet, and a cross-shaped pressure block is arranged inside the upper mold cavity according to the cavity of the limit groove of the mold aluminum shell.
[0005] Preferably, the upper mold is a wooden upper mold.
[0006] Preferably, the lower mold is made of AL6061 material, and the entire lower mold is sprayed with Teflon.
[0007] Preferably, the cross pressing blocks are wooden pressing blocks.
[0008] The utility model has the following beneficial effects:
[0009] 1. The lower mold is sprayed with Teflon for easy demoulding;
[0010] 2. A small pinhole needs to be opened in the center of the circular hole to facilitate vacuum forming;
[0011] 3. The upper mold shell is inlaid with 1mm thick iron sheet to press the periphery, and the rest is made of ordinary wood. The internal structure of the upper mold is equipped with cross-shaped pressure blocks according to the cavity of the limit groove of the mold aluminum shell to prevent deformation of the internal structure of the limit groove and uneven molding. BRIEF DESCRIPTION OF THE DRAWINGS
[0012] The utility model is described in detail below with reference to the accompanying drawings and specific implementation methods;

[0015] Figure 3 It is a schematic diagram of the bottom of the upper mold of the utility model. DETAILED DESCRIPTION
[0016] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further described below in conjunction with specific implementation methods.
[0017] Reference Figure 1-3 The present specific implementation adopts the following technical scheme: an upper and lower mold structure of an aluminum shell blister tray, comprising an upper mold 1 and a lower mold 2, a vacuum circular hole 3 with a diameter of 4 mm is arranged at the bottom of the lower mold 2, the distance between the circular hole 3 and the characteristic surface is 1.5 mm, a pinhole is opened in the center of the circular hole 3, the outer shell of the upper mold 1 is surrounded by a 1 mm thick iron sheet 4, and a cross-shaped pressing block 5 is arranged inside the upper mold cavity according to the cavity of the limit groove of the mold aluminum shell.
[0018] It is worth noting that the upper mold 1 is a wooden upper mold.
[0019] It is worth noting that the lower mold 2 is made of AL6061 material, and the entire lower mold is sprayed with Teflon.
[0020] In addition, the cross pressing blocks 5 are wooden pressing blocks.
[0021] The aluminum shell mold of this specific implementation method consists of an upper mold and a lower mold. The lower mold is made of AL6061 material with good mechanical properties. The lower mold is sprayed with Teflon for easy demoulding. There is a vacuum circular hole with a diameter of 4mm at the bottom of the lower mold. The distance from the circular hole to the characteristic surface is 1.5mm. A small pinhole needs to be opened in the center of the circular hole for vacuum forming. The upper mold shell is inlaid with 1mm thick iron sheet to press the periphery, and the rest is made of ordinary wood. The internal structure of the upper mold is provided with a cross-cross pressure block according to the cavity of the aluminum shell limit groove of the mold to prevent the internal structure of the limit groove from deformation and uneven molding.
[0022] The tray molding of this specific embodiment is to soften the 2mm ABS+TPU substrate at high temperature and then mold it by negative pressure adsorption. The higher the mold, the more complex the structure and the more uneven the molding. Therefore, the upper mold is used to actively feed the raw materials and allow the edge materials to diffuse more to the inside.
[0023] The above shows and describes the basic principle and main features of the utility model and the advantages of the utility model. Those skilled in the art should understand that the utility model is not limited by the above embodiments. The above embodiments and descriptions are only for explaining the principle of the utility model. Without departing from the spirit and scope of the utility model, the utility model may have various changes and improvements, which fall within the scope of the utility model to be protected. The scope of protection claimed by the utility model is defined by the attached claims and their equivalents.
