Description

Technical Field

[0001] This utility model relates to the technical field of vehicle inverter production and processing equipment, and in particular to a forming mold for a vehicle inverter industrial control box. Background Technology

[0002] As a core component for vehicle power conversion, the vehicle inverter's associated industrial control box must possess robust structure and resistance to high and low temperature shocks. Currently, most vehicle inverter industrial control boxes are manufactured using injection molding, which involves injecting molten plastic into an injection cavity and allowing it to cool and solidify to form the control box body.

[0003] However, existing vehicle inverter industrial control boxes need to be removed from the mold manually or by simple mechanical means after molding. Because the injection cavity and the industrial control box body are tightly fitted, the edges of the product are easily scratched or squeezed during the material removal process, resulting in product scrap. At the same time, the temperature of the industrial control box after molding is high, and manual material removal is prone to injury.

[0004] More importantly, traditional molds rely on natural cooling or a single cooling channel for cooling, resulting in a slow cooling rate of the molten material within the injection cavity. Utility Model Content

[0005] In view of the problems mentioned in the background art, the purpose of this utility model is to provide a molding die for an industrial control box for an on-board inverter.

[0006] The present invention adopts the following technical solution.

[0007] A molding die for an industrial control box of an on-board inverter includes a lower die, an upper die, and an industrial control box body. The upper die is located above the lower die, and the industrial control box body is located on the outer surface of the lower die. The lower die is characterized by having a base below it, a fixed frame connected above the base, a hydraulic cylinder mounted above the fixed frame, the output end of the hydraulic cylinder connected to the upper die, a fixed shell inside the lower die, the fixed shell and the lower die forming a cooling cavity, the cooling cavity being filled with coolant, a coolant exchange pipe at the bottom of the lower die, a circulation section inside the fixed shell, and a material handling section on one side of the lower die.

[0008] To improve the cooling rate of the molten material in the injection cavity, the circulation section includes a circulation pump, a liquid extraction pipe, and a liquid outlet pipe. The circulation pump is installed inside the fixed housing, the liquid extraction pipe passes through the fixed housing and is connected to the input end of the circulation pump, and the liquid outlet pipe passes through the fixed housing and is connected to the output end of the circulation pump.

[0010] To improve the safety of the mold forming die for the vehicle inverter industrial control box, the material handling part includes a material handling rod, a moving plate, a threaded rod, and a material handling motor. The material handling motor is located between the lower mold and the base. The output end of the material handling motor is connected to the threaded rod. The moving plate is threadedly connected to the threaded rod, and the side of the moving plate closest to the lower mold is connected to the material handling rod. The end of the material handling rod away from the moving plate is located inside the lower mold and is in contact with the industrial control box body.

[0011] Preferably, a stabilizing rod is connected to the inner side of the base, the stabilizing rod passes through the movable plate, and is arranged parallel to the threaded rod.

[0012] To improve the positioning accuracy of the mold closing, a positioning rod is connected to the lower part of the upper mold, and the end of the positioning rod away from the upper mold is inserted into the lower mold.

[0013] Preferably, a rubber plug is provided on one side of the lower mold, and the upper mold, lower mold and rubber plug together form an injection cavity, and the shape and size of the injection cavity are the same as those of the industrial control box body.

Detailed Implementation

[0024] The technical solutions of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0025] Combination Figures 1-6 As shown, a molding die for an industrial control box of an on-board inverter includes a lower die 1, an upper die 2, and an industrial control box body 3. The upper die 2 is located above the lower die 1, and the industrial control box body 3 is located on the outer surface of the lower die 1. The lower die 1 is characterized by having a base 4 below it, a fixing frame 5 connected above the base 4, a hydraulic cylinder 6 mounted above the fixing frame 5, the output end of the hydraulic cylinder 6 being connected to the upper die 2, a fixing shell inside the lower die 1, the fixing shell and the lower die 1 forming a cooling cavity 7, the cooling cavity 7 being filled with coolant, a coolant exchange pipe 8 at the bottom of the lower die 1, a circulation section inside the fixing shell, and a material handling section on one side of the lower die 1.

[0026] The circulation section includes a circulation pump 9, a suction pipe 10, and an outlet pipe 11. The circulation pump 9 is installed inside the fixed housing. The suction pipe 10 passes through the fixed housing and is connected to the input end of the circulation pump 9. The outlet pipe 11 passes through the fixed housing and is connected to the output end of the circulation pump 9.

[0027] Among them, the connection between the bottom surface and the side wall inside the lower mold 1 is a guide slope 12.

[0028] The material handling unit includes a material handling rod 13, a moving plate 14, a threaded rod 15, and a material handling motor 16. The material handling motor 16 is located between the lower mold 1 and the base 4. The output end of the material handling motor 16 is connected to the threaded rod 15. The moving plate 14 is threadedly connected to the threaded rod 15, and the side of the moving plate 14 closest to the lower mold 1 is connected to the material handling rod 13. The end of the material handling rod 13 away from the moving plate 14 is located inside the lower mold 1 and is in contact with the industrial control box body 3.

[0029] The base 4 has a stabilizing rod 17 connected to its inner side. The stabilizing rod 17 passes through the movable plate 14 and is arranged parallel to the threaded rod 15.

[0030] The upper mold 2 is connected to a positioning rod 18 at its lower end, and the end of the positioning rod 18 away from the upper mold 2 is inserted into the lower mold 1.

[0031] Among them, a rubber plug 19 is provided on one side of the lower mold 1, and the upper mold 2, the lower mold 1 and the rubber plug 19 together form an injection cavity 20, and the shape and size of the injection cavity 20 are the same as those of the industrial control box body 3.

[0032] The upper mold 2 is connected to the upper part of the injection tube 21, and the injection tube 21 is connected to the injection cavity 20.

[0033] During injection molding, hydraulic cylinder 6 presses down on upper mold 2, causing upper mold 2 to close with lower mold 1, and rubber plug 19 is placed in the gap between upper mold 2 and lower mold 1, thus forming injection cavity 20. Molten material is injected into injection cavity 20 through injection tube 21. After injection cavity 20 is filled with molten material, coolant at the bottom of cooling cavity 7 is sprayed out from outlet tube 11 through liquid extraction tube 10 and circulation pump 9 to cool the upper part of cooling cavity 7 (close to molten material, where coolant absorbs heat). Then, the coolant will flow back to the bottom of cooling cavity 7 (away from molten material, where coolant releases heat) under the guidance of guide slope 12 for the next cycle. This achieves rapid cooling of the industrial control box body 3 after injection molding.

[0034] During material handling, the hydraulic cylinder 6 drives the upper mold 2 to reset. At the same time, the rubber plug 19 is removed, and the threaded rod 15 is driven to rotate by the material handling motor 16. With the assistance of the stabilizing rod 17, the moving plate 14 is driven to move the material handling rod 13 towards the lower mold 1. The material handling rod 13 pushes the processed industrial control box body 3 out of the lower mold 1, completing the material handling.

[0035] The vehicle inverter industrial control box forming mold of this utility model can not only improve the safety of mold use, but also improve the accuracy of mold closing and positioning, and make material picking more convenient. More importantly, compared with traditional molds, the vehicle inverter industrial control box forming mold of this application has a faster cooling speed and higher production efficiency.

Those skilled in the art can understand that implementing all or part of the above-described embodiments and making equivalent changes in accordance with the claims of the present utility model are still within the scope of the utility model.
