Description

Technical Field

[0001] The utility model relates to a tray mould, in particular to a top cover bracket blister tray mould. Background Art

[0002] The top cover is one of the core components of the power battery. The top cover is inseparable from the bracket. The bracket is generally transported and installed on a blister-formed pallet. Due to the various styles of the top cover, the bracket is relatively irregular, which makes it easy to stretch and deform during molding.

[0003] In summary, the utility model designs a top cover bracket blister tray mold which prevents deformation. Utility Model Content

[0004] In view of the deficiencies in the prior art, the utility model aims to provide a top cover bracket blister tray mold, the side and top surfaces of the mold are treated with borax, the characteristic positions are treated with Teflon to prevent demolding and stretching, and the bottom surface of the mold is perforated. This structure greatly solves the problem of waste caused by molding deformation.

[0005] In order to achieve the above-mentioned purpose, the utility model is realized through the following technical scheme: a top cover bracket blister tray mold, including a mold base, mold sides, mold top surface, characteristic positions and circular holes, a circular hole with a diameter of 4 mm is arranged at the bottom of the mold base, the mold sides and mold top surface on the mold base are sandblasted, and except for the mold sides and mold top surface, the rest are characteristic positions, and the characteristic positions are sprayed with Teflon.

[0006] Preferably, only 1 mm is left at the characteristic position on the top surface of the circular hole, a small pinhole is pierced at the exact center of the circular hole, and all the circular holes are connected by CNC processing to form a vacuum track.

[0007] Preferably, the circular hole is a hollow groove with a depth of 0.3 mm.

[0008] The beneficial effects of the utility model: the utility model has a reasonable structural design, the side and top surfaces of the mold are treated with borax, the characteristic positions are treated with Teflon to prevent demoulding and stretching, and the bottom surface of the mold is punched. This structure greatly solves the problem of waste caused by molding deformation. BRIEF DESCRIPTION OF THE DRAWINGS

[0009] The utility model is described in detail below with reference to the accompanying drawings and specific implementation methods;

[0010] Figure 1 It is a structural schematic diagram of the utility model;

[0011] Figure 2 It is a bottom schematic diagram of the utility model. DETAILED DESCRIPTION

[0012] 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.

[0013] Reference Figure 1-2 This specific implementation adopts the following technical scheme: a top cover bracket blister tray mold, including a mold base 1, a mold side 2, a mold top surface 3, a characteristic position 4 and a circular hole 5. A circular hole 5 with a diameter of 4 mm is arranged at the bottom of the mold base 1. The mold side 2 and the mold top surface 3 on the mold base 1 are sandblasted. Except for the mold side 2 and the mold top surface 3, the rest are characteristic positions 4, and the characteristic positions 4 are sprayed with Teflon.

[0014] It is worth noting that only 1 mm is left at the characteristic position on the top surface of the circular hole 5, and a small pinhole is pierced in the center of the circular hole. All the circular holes are connected by CNC processing to form a vacuum track.

[0015] In addition, the circular hole 5 is a hollow groove with a depth of 0.3 mm.

[0016] The mold of this specific embodiment is made of AL6061 material with good processing performance and stable thermal expansion coefficient through machining, and the mold consists of a mold base and a mold cavity. The side and top surfaces of the mold are sandblasted, and the internal structural feature positions are treated with Teflon spraying to prevent mold release deformation.

[0017] The bottom of the mold adopts a 4mm diameter round hole design. Only 1mm is left at the characteristic position on the top surface of the round hole to prevent the hole from being broken and causing vacuum. A small pinhole will be punched in the center of the round hole. All the round holes will finally be connected through CNC processing. The hollow groove with a depth of 0.3mm is used to facilitate the vacuum to pass through the mold evenly for plastic forming. Punching effectively solves the problem of product failure.

[0018] The mold of this specific implementation method is placed on a vacuum equipment machine and is formed by negative pressure. The structure is reasonably designed. The side and top surfaces of the mold are treated with borax, and the characteristic positions are treated with Teflon to prevent demolding and stretching. The bottom surface of the mold is perforated. This structure greatly solves the problem of waste caused by molding deformation.

[0019] 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.
