Beneficial effects

[0010] This integrated molding device for the AB beam of the new energy vehicle battery pack uses a drive motor to rotate gears, which in turn drive racks on both sides to move apart. This causes the front and rear molds to unfold, exposing the battery tray AB beam. A hydraulic cylinder drives a pallet to move upward and lift the battery tray AB beam, preventing it from deforming due to gravity. A hydraulic telescopic rod drives the core mold to be pulled outward, while the battery tray AB beam is restricted from moving by the side plates. This allows the core mold to be extracted from inside the battery tray AB beam, thus achieving the goal of quickly removing the cast battery tray AB beam. This integrated molding device for the AB beam of the new energy vehicle battery pack uses a hydraulic cylinder to drive the support plate to move downward and retract. A drive motor then reverses the gears, which in turn drive the racks on both sides to retract, thus closing the front and rear molds. An elastic plate controls the insertion of a clamping head into a slot, locking the positions of the front and rear molds. A hydraulic telescopic rod then drives the core mold to insert into the interior of the front and rear molds, forming a cavity. Molten metal is injected into this cavity through a casting hole to form the battery tray AB beam. An external cooling water circulation system circulates the water inside the front and rear molds, accelerating the rapid integrated molding of the battery tray AB beam. Attached Figure Description

[0014] Please see Figure 1-5 The integrated molding device for the AB beam of the new energy vehicle battery pack includes a base frame 1. Two symmetrically arranged slide rails 2 are fixedly installed on the top of the base frame 1. A slider 3 is slidably installed inside the slide rails 2. A front mold 4 and a rear mold 5 are slidably installed on the top of the base frame 1 through the slide rails 2 and the slider 3 respectively. The front mold 4 is a concave mold and the rear mold 5 is a convex mold. When the front mold 4 and the rear mold 5 are combined and closed, the cavity of the AB beam of the battery pack is formed. A side plate 6 is provided on the left side of the front mold 4 and the rear mold 5. The bottom of the side plate 6 is fixedly installed to the base frame 1. The side plate 6 closes the left side of the front mold 4 and the rear mold 5.

[0015] Please see Figure 1-5 A hydraulic telescopic rod 7 is fixedly installed inside the base frame 1. A vertical plate 8 is fixedly installed at the output end of the hydraulic telescopic rod 7. A core mold 9 is fixedly installed on the side of the vertical plate 8. A core mold hole 10 corresponding to the core mold 9 is opened on the surface of the side plate 6. The hydraulic telescopic rod 7 can drive the vertical plate 8 and the core mold 9 to move, so that the core mold 9 can be disassembled into the cavity between the front mold 4 and the rear mold 5, thereby forming the cavity of the battery tray AB beam 12.

[0016] Please see Figure 1-5 The top of the rear mold 5 has a pouring hole 11. The cavity formed between the front mold 4, the rear mold 5 and the core mold 9 contains a battery tray AB beam 12. Molten metal can be poured into the cavity through the pouring hole 11, and the molten metal will form the battery tray AB beam 12 in the cavity, thus achieving one-piece molding.

[0017] Please see Figure 1-5The front mold 4 has elastic plates 13 fixedly installed on both the top and bottom sides, and a clamping head 14 is fixedly installed at the end of the elastic plate 13. The rear mold 5 has a clamping groove 15 corresponding to the clamping head 14 on both the top and bottom. The front mold 4 and the rear mold 5 are connected to each other by the elastic plate 13, the clamping head 14 and the clamping groove 15. The cross-section of the end of the clamping head 14 that is inserted into the clamping groove 15 is trapezoidal, which facilitates the clamping head 14 and the clamping groove 15 to be squeezed and ejected by the trapezoidal inclined surface.

[0018] Please see Figure 1-5 A hydraulic cylinder 16 is embedded inside the base frame 1. A support plate 17 is fixedly installed at the output end of the hydraulic cylinder 16. The support plate 17 is placed at the bottom of the front mold 4 and the rear mold 5. The hydraulic cylinder 16 can drive the support plate 17 to move upward, so that the support plate 17 can lift the battery tray AB beam 12 and ensure that the battery tray AB beam 12 will not deform due to gravity.

[0019] Please see Figure 6-7 Both the front mold 4 and the rear mold 5 have racks 18 fixedly mounted on their bottoms, and gears 19 mesh between the two racks 18. The shaft of the gear 19 is fixedly mounted to the output end of the drive motor 20, which is embedded inside the base frame 1.

[0020] Please see Figure 1-7 The front mold 4 and the rear mold 5 are hollow, serving as cooling water chambers. The outer walls of both molds are fitted with symmetrically arranged cooling water nozzles 21, which are connected to an external cooling water circulation system. This system controls water to enter the cooling water chamber from one end of the cooling water nozzle 21 and exit from the other end, thus creating a water circulation system and enabling rapid forming of the battery tray AB beam 12.

[0021] In use, the drive motor 20 drives the gear 19 to rotate, which in turn drives the racks 18 on both sides to move away, causing the front mold 4 and the rear mold 5 to unfold back and forth, exposing the battery tray AB beam 12. The hydraulic cylinder 16 drives the support plate 17 to move upward and lift the battery tray AB beam 12, preventing it from falling and deforming due to gravity. The hydraulic telescopic rod 7 drives the core mold 9 to be pulled outward, while the battery tray AB beam 12 is restricted from moving by the side plate 6, thus realizing the extraction of the core mold 9 from the inside of the battery tray AB beam 12, thereby achieving the purpose of quickly removing the cast battery tray AB beam 12.

[0022] The hydraulic cylinder 16 drives the support plate 17 to move down and retract; the drive motor 20 drives the gear 19 to reverse, and the gear 19 drives the racks 18 on both sides to retract, thereby realizing the mutual closing of the front mold 4 and the rear mold 5. The elastic plate 13 controls the chuck 14 to insert into the chuck 15 to lock the position of the front mold 4 and the rear mold 5. Then, the hydraulic telescopic rod 7 drives the core mold 9 to be inserted into the interior of the front mold 4 and the rear mold 5. The core mold 9, the front mold 4 and the rear mold 5 form a cavity. The molten metal can be injected into the cavity through the pouring hole 11 to form the battery tray AB beam 12. The water inside the front mold 4 and the rear mold 5 is circulated by the external cooling water circulation equipment, thereby accelerating the rapid one-piece molding of the battery tray AB beam 12.
