Description

Technical Field

[0001] This utility model relates to the field of automotive battery casing technology, specifically a four-sided inverted mold for an automotive battery casing. Background Technology

[0002] The specific roles vary slightly depending on the type of electric vehicle. In pure electric vehicles equipped solely with a battery, the battery serves as the sole power source for the vehicle's drive system. In hybrid electric vehicles, which combine a conventional engine (or fuel cell) with a battery, the battery can function as both the primary and auxiliary power source for the drive system. Therefore, at low speeds and during startup, the battery acts as the primary power source; during full-load acceleration, it functions as an auxiliary power source; and during normal driving, deceleration, or braking, it functions as an energy storage device.

[0003] When installing and using current car batteries, a battery casing structure needs to be installed on the outside. During the production of the battery casing, the stretching effect of pressing the plate downwards can result in uneven thickness of the plate after stretching, which affects the subsequent protection of the battery. Furthermore, after forming, the edges need to be pressed into a frame shape using additional equipment, making the production process cumbersome and affecting efficiency. Utility Model Content

[0004] The purpose of this utility model is to provide a four-sided undercut mold for an automotive battery casing, in order to solve the problem mentioned in the background art that when current automotive batteries are installed and used, a battery casing structure needs to be installed on the outside of them. However, during the production of the battery casing, the stretching effect formed by pressing the plate downwards results in uneven thickness of the plate after stretching, which affects the subsequent protection of the battery. Furthermore, after forming, the edges need to be pressed into a frame shape using additional equipment, which leads to a cumbersome production process and affects efficiency.

[0005] To achieve the above objectives, this utility model provides the following technical solution:

[0006] A four-sided undercut mold for an automotive battery casing includes a supporting base plate. A mating top plate is horizontally mounted on the top surface of the supporting base plate. Mounting side strips are horizontally and symmetrically welded to both sides of the supporting base plate and the mating top plate. Fixing through holes are evenly distributed on the top surface of the mounting side strips. A forming channel is horizontally formed on the top surface of the supporting base plate. An edge channel is formed at the top of the forming channel. A bottom support plate is vertically engaged with the inner side of the forming channel. Guide pillars are symmetrically and fixedly inserted into the top surface of the supporting base plate. An extrusion block is fixedly engaged with the bottom surface of the mating top plate. Movable vertical grooves are symmetrically formed on the top surface of the mating top plate. The inner side of the movable vertical grooves is vertically... A vertical insert block is inserted vertically. Mounting screws are evenly inserted into the top surface of the mating top plate. A movable channel is horizontally opened on the inner side wall of the supporting base plate. A bottom fixing plate is horizontally engaged on the inner side edge of the movable channel. Limiting holes are evenly opened on the inner bottom surface of the movable channel. A top-connecting spring is fixedly connected to the inner side edge of the limiting holes. A pressure frame is horizontally engaged on the bottom surface of the mating top plate. A vertical groove is vertically opened on the side edge of the vertical insert block. A fixing plate is horizontally inserted into the inner side edge of the vertical groove. A mating spring is fixedly engaged on the bottom surface of the fixing plate. Guide grooves are symmetrically opened on the bottom surface of the mating top plate. A main housing is provided on the inner side edge of the forming channel.

[0007] In a preferred embodiment of this utility model, the supporting base plate and the mating top plate are arranged in parallel and superimposed on each other, and the mounting side strips are fixedly installed in pairs symmetrically and parallelly at the two side edges of the supporting base plate and the mating top plate.

[0008] In a preferred embodiment of this utility model: the forming channel is opened at the center of the top surface of the supporting base plate, and the bottom end extends vertically downward to the interior of the movable channel to maintain connection; the edge channel is opened horizontally at the edge of the top opening of the forming channel; and the bottom end of the bottom support plate is fixedly connected to the center of the top surface of the bottom fixing plate.

[0009] In a preferred embodiment of this utility model: the guide columns are fixedly and symmetrically inserted into each other on the top surface of the support base plate near the four corner slots, and the top of the guide column is correspondingly inserted into the inner side of the guide groove. The extrusion block is fixedly installed at the center groove position of the bottom surface of the mating top plate and is fixedly connected by the installation screw. The movable vertical groove is vertically and symmetrically opened at the center line of the top surface of the mating top plate near both ends.

[0010] As a preferred embodiment of this utility model: the bottom end of the vertical insert is fixedly connected to the top surface of the pressure frame, the movable channel is horizontally opened on the inner side of the support base plate near the bottom surface, the top ends of the top springs are vertically connected to the bottom surface of the bottom fixed plate, the pressure frame is arranged in a U-shape, and the pressure frame and the edge channel are arranged in a superimposed and corresponding manner.

[0011] As a preferred embodiment of the present invention: the side of the vertical groove is through-cut, and the two ends of the fixing plate are horizontally welded to the inner side wall of the movable vertical groove. The guide groove is symmetrically cut on the bottom surface of the mating top plate near the four corners, and the main shell is horizontally set between the bottom support plate and the extrusion top block.

[0012] Compared with the prior art, the beneficial effects of this utility model are:

[0013] This invention horizontally connects a supporting base plate to the equipment base plate, while a mating top plate horizontally connects to the equipment's punching head. Bolts pass through the fixing holes to secure the side strips. The main shell, in the form of a plate, is horizontally placed at the top opening of the forming channel. When the punching head presses downwards, the mating top plate snaps downwards onto the top surface of the supporting base plate, allowing the top of the guide column to be inserted into the guide groove. This effectively prevents misalignment between the supporting base plate and the mating top plate, and allows the bottom pressing block to press the plate-shaped main shell downwards. Entering the forming channel, the shell shape is formed. Then, the vertical insert is pressed downward by the stamping structure on the top surface, causing the vertical insert to move downward along the movable vertical groove. This causes the bottom pressing frame to press downward against the top opening edge of the main shell into the edge channel, forming a frame shape. After the top plate is lifted, the top spring pushes the bottom support plate upward into the channel, causing the bottom support plate to push the main shell outward from the top surface, forming a demolding effect. The stable extrusion forming structure makes the shell forming more complete and comprehensive. At the same time, the integrated stamping forming of the frame greatly improves the production efficiency of the battery shell. Attached Figure Description

[0022] Please see Figure 2-5In this embodiment of the present invention, a four-sided inverted mold for an automotive battery casing is provided. A movable channel 13 is horizontally opened on the inner wall of the supporting base plate 1. A bottom fixing plate 14 is horizontally engaged with the inner side of the movable channel 13.

The mounting side strip 3 is fixed in place by bolts passing through the fixing through hole 4. The main shell 22, in plate form, is horizontally placed at the top opening of the forming channel 5. When the equipment's punching head presses downwards, the mating top plate 2 is pulled downwards and snapped onto the top surface of the supporting base plate 1. The top of the guide column 8 is then inserted into the guide groove 21, effectively preventing misalignment between the supporting base plate 1 and the mating top plate 2. In this situation, the bottom extrusion block 9 presses the plate-shaped main shell 22 downward into the forming channel 5, forming a shell shape. Then, the top stamping structure presses the vertical insert 11 downward, causing the vertical insert 11 to move downward along the movable vertical groove 10. This causes the bottom pressing frame 17 to press downward against the top opening edge of the main shell 22 into the edge channel 6, forming a frame shape. After the top plate 2 is lifted, the top spring 16 pushes the bottom support plate 7 upward into the channel, causing the bottom support plate 7 to push the main shell 22 outward to form a demolding effect.
