Description

Technical Field

[0001] This application relates to the technical field of energy storage system mold processes, and particularly to a runway-shaped mold applied to an energy storage system. Background Art

[0002] An energy storage system is an integrated device composed of an energy storage battery pack and supporting electrical equipment, which is used to comprehensively realize the application of electrochemical energy storage, such as charge and discharge, AC-DC conversion, etc. The supporting electrical equipment generally includes a power conversion system (PCS), a battery management system (BMS), an energy management system (EMS), and some peripheral circuits. During the actual operation of the energy storage system, with the expansion of the supporting electrical equipment and the energy storage battery capacity, the overall volume of the energy storage system is also getting larger and larger, resulting in larger and larger structural components on the internal structure or external housing of the energy storage system.

[0003] In an energy storage system, runway-shaped structural components are a common type of structural components. The annular length of the runway-shaped structural components generally does not exceed 300 - 600 mm and is manufactured by gas-assisted injection molding process. The gas-assisted injection molding process refers to injecting inert high-pressure nitrogen when the plastic is filled into the cavity appropriately. The gas pushes the molten plastic to continue filling the cavity, and a gas pressure holding process is used to replace the plastic pressure holding process in an injection molding technology. However, since gas-assisted injection molding requires blowing air into the cavity filled with plastic, at a certain melting temperature of the plastic, excess waste is quickly blown out. This process has strict requirements on the length. In order to manufacture runway-shaped structural components with an annular length exceeding 300 - 600 mm, it is often necessary to increase the blowing air pressure, which is likely to blow the product, or if the air pressure is too small, it is likely that the plastic has not completed the process after cooling, resulting in the rupture of the runway-shaped structural components.

[0004] Therefore, as the volume requirements of the runway-shaped structural components in the energy storage system increase, the traditional method of manufacturing runway-shaped structural components by gas-assisted injection molding process still has the above deficiencies.

[0043] The mold base is for being placed on a horizontal plane, and its upper surface is vertically upward to form an opening, and inside the opening is the runway-shaped groove. After injecting plastic into the runway-shaped groove, the plastic fits against the inner side of the runway-shaped groove due to gravity, forming a runway-shaped structural member in the form of a plastic part.

[0044] The runway-shaped structural member support is placed in the runway-shaped groove. After injecting plastic into the runway-shaped groove, the plastic wraps the runway-shaped structural member support, forming a coated structure.

[0059] As Figure 2 shown, the reinforcing ribs 203 are vertically arranged on the surface of the sheet-shaped annular bracket 200.

[0060] As one of the preferred embodiments, as Figure 2 shown, the runway-shaped structural member bracket further includes:

[0061] A bracket handle 205, which forms an integral runway shape with the sheet-shaped annular bracket 200.

[0062] The bracket handle 205 and the sheet-shaped annular bracket 200 form different shapes to facilitate the placement or removal of the runway-shaped structural member bracket.

[0069] As one of the preferred embodiments, as Figure 2 shown, the first positioning structure is a positioning post 204.

[0070] As Figure 2 shown, the positioning post 204 is provided on the side surface of the sheet-shaped annular bracket 200. When setting, the side surface is horizontal upward or horizontal downward.

[0078] S100, place the runway - type structural member bracket in the runway - type groove of the mold base;

[0079] S101, inject plastic into the runway - type groove;

[0080] S102, wait for the plastic to cool until the plastic is integrated with the runway - type structural member bracket to form a runway - type structural member.

[0081] Among them, in step S101, the heated plastic can be injected through an injection molding machine, and an auxiliary device is used to ensure the filling effect of the plastic.

[0083] Figure 6 For the schematic diagram of the runway - type structural member in a preferred embodiment, as Figure 6 shown, based on the original runway - type structural member bracket 500, after the plastic cools until the plastic is integrated with the runway - type structural member bracket 500 and is taken out from the runway - type mold applied to the energy storage system, the runway - type structural member 400 has a stable structure and is not limited by size. According to the actual requirements of the energy storage system, large - size runway - type structural members can be formed. At the same time, compared with the gas - assisted molding process, there are no problems such as damage to the runway - type structural member or process defects.

[0084] As a preferred embodiment, in order to improve the yield and structural strength of the runway-shaped structural member, preferably, an injection molding machine is used to perform step S101, and parameter optimization and adjustment are carried out as follows:

[0085] To solve the mold forming problem, set the nozzle temperature parameter of the injection molding equipment to 245 °C, and there are 6 hot runners in the mold, and controllable temperature electric heating equipment is respectively set. The first-stage electric heating parameter: 240 ± 10 °C; the second-stage electric heating parameter: 235 ± 10 °C; the third-stage electric heating parameter: 235 ± 10 °C; the fourth-stage electric heating parameter: 230 ± 10 °C; the fifth-stage electric heating parameter: 230 ± 10 °C; the sixth-stage electric heating parameter: 230 ± 10 °C;

[0086] The clamping pressure of the injection molding equipment: 140 ± 10 mpa, the injection plastic pressure 100 ± 10 mpa, and it is injected in three stages. The injection molding holding pressure is 15 ± 3 mpa and is completed in two stages.

[0087] The injection plastic speed is 30 ± 3 mm / min, the plasticizing stroke is 230 ± 10 mm, and the action is completed by injecting in three stages, among which the second-stage stroke is 50 ± 5 mm and the third-stage stroke is 30 ± 3 mm.

[0088] The injection time is 10 ± 2 s, the cooling time is 90 ± 10 s, the holding pressure time is 2 ± 0.2 s, and the whole cycle is completed in 140 ± 10 s.

[0089] According to the material selection of the plastic, the above parameters can be adjusted accordingly.

[0090] As a preferred embodiment, the plastic is selected as PC / ABS (spray-free) material. The spray-free material can improve the appearance of the formed runway-shaped structural member product, achieving a certain effect similar to spraying (high gloss, strong texture, multiple dazzling colors), and can also improve the product performance, such as weather resistance, chemical resistance, and enhance the physical properties of the material itself. At the same time, the melt physical properties of the spray-free material are optimized, and the melt index is increased to 25 g / 10 min (ISO1133).
