[0002] Against the backdrop of the rapid growth of China's energy storage market, demand for energy storage inverter housings continues to expand. Although existing energy storage inverter housings are primarily manufactured using a magnesium-aluminum alloy die-casting process, this method has significant drawbacks, such as long manufacturing times, high costs, and lengthy product development cycles, making it difficult to meet market demands for rapid delivery. With the growing demand for lightweighting and cost-effectiveness, plastic housings are increasingly being used in energy storage equipment and other outdoor products, such as base stations. However, the production process for these plastic housings also faces significant technical challenges. Currently, the manufacturing of plastic housings involves a semi-automated process, particularly in the nozzle treatment process. While this semi-automated method offers improvements over fully manual operations, it still suffers from low efficiency and unstable product quality control. Manual intervention is required to remove the nozzles, which not only reduces production efficiency but also leads to chipping and scratching of the finished product due to manual inaccuracies, compromising the product's appearance and structural consistency. Prolonged manual operation can also lead to operator fatigue and increase the risk of production accidents. Summary of the Invention

DETAILED DESCRIPTION

[0017] The present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0018] like Figures 1 to 4As shown, the utility model is an automatic punching nozzle device for a plastic shell, comprising a bottom plate 1, the bottom plate 1 is connected to a top plate through a bracket, the top plate is connected to an upper template 3 through a movable rod through a first cylinder 2, the two sides of the upper template 3 are connected to a pre-pressing plate 5 through a connecting rod 4 with a spring, the lower side of the pre-pressing plate 5 is connected to a pre-pressing block 6, the bottom side of the middle part of the upper template 3 is connected to an upper knife 8 through an upper knife base 7, a jig 9 with a lower knife 11 is provided on the lower side of the channel on the pre-pressing plate 5, the jig 9 is connected to the bottom plate 1 through a lower template 10, and nozzle grooves are provided on the jig 9, the lower template 10 and the bottom plate 1. The first cylinder 2 drives the upper template 3 to move through the movable rod. The upper template 3 drives the pre-pressing plate 5 and the pre-pressing block 6 to move through the connecting rod 4, and also drives the upper knife base 7 and the upper knife 8 to move. The upper knife 8 cooperates with the lower knife 11 on the fixture 9 to cut off the sprue of the plastic shell. The sprue falls from the sprue groove, and the process is completed. It is convenient, efficient and practical to use.

[0019] The present invention is further characterized in that both sides of the upper template 3 are connected to the base plate 1 through guide pillars 12. The guide pillars 12 can realize the motion positioning of the upper template 3, and have good practicality.

[0020] The utility model further has four connecting rods 4, and they are respectively located at the four vertices of the pre-compression plate 5. The connecting rods 4 respectively located at the four vertices of the pre-compression plate 5 and sleeved with springs have good stability.

[0021] The utility model is further provided that the size of the channel is greater than or equal to the size of the upper knife base 7. This makes it easy for the upper knife 8 on the upper knife base 7 to smoothly perform nozzle removal on the product, and has good practicality.

[0022] Furthermore, the bottom side of the lower template 10 is connected to a guide rail 14 via a slider 13, and the left side of the lower template 10 is connected to a driving component via a buckle 16. The driving component drives the buckle 16 and the slider 13 on the bottom side of the lower template 10 to reciprocate on the guide rail 14, thereby performing work according to production needs.

[0023] The present invention further provides that the driving component is a screw or a second cylinder. Preferably, the driving component is the second cylinder, and the second cylinder and the buckle 16 can be used to reciprocate the lower template 10. Although the screw can achieve reciprocating motion, it requires a larger space to avoid the screw interfering with the nozzle groove.

[0024] The present invention is further provided with a fixed limit block 15 at the left end of the guide rail 14. The limit block 15 can prevent the slider 13 from sliding out of the guide rail 14, and has a limiting effect on the lower template 10, which is practical.

[0025] The working principle of this utility model is:

[0026] After the plastic shell product is removed from the mold by the robot, it is placed in the initial position of the jig 9. The robot withdraws from the jig 9 and hovers to wait. The second cylinder drives the lower template 10 to the right through the buckle 16. The slider 13 assists the movement of the lower template 10 on the guide rail 14 and stops at the right limit block 15.

[0027] The movable rod on the first cylinder 2 moves downward, driving the upper template 3 to move downward. As the upper template 3 moves downward, when the pre-pressing block 5 and the product are initially in contact, within the stroke of the connecting rod 4, the pre-pressing plate 5 moves in the opposite direction to the upper template 3. Due to the buffering effect of the spring sleeved on the connecting rod 4, the pre-pressing block 6 and the product are in close contact. When the spring is compressed to the limit, the upper template 3 drives the upper knife 8 to move to the top of the product nozzle in a close contact state, and then the upper knife 8 and the lower knife 11 are in a shearing position. The product nozzle is punched out and the nozzle falls into the knife nozzle groove and is collected and processed uniformly.

[0028] After the punching is completed, the first cylinder 2 drives the upper template 3 to move upward. Due to the action of the spring, the pre-pressing block 6 of the pre-pressing plate 5 gradually separates from the product until it is completely separated. The upper template 3 drives the pre-pressing plate to reset through the connecting rod 4; after the upper template 3 is reset, the lower template 10 is synchronously reset to the initial position, and the robot hovering above adsorbs the product away from the lower template 10, thereby completing a cycle of automated punching of the nozzle.

[0029] The description and application of the present invention here are illustrative and are not intended to limit the scope of the present invention to the above-described embodiments. Variations and changes to the embodiments disclosed herein are possible, and actual replacements of the embodiments and various equivalent components are well known to those of ordinary skill in the art. It should be clear to those skilled in the art that the present invention can be implemented in other forms, structures, arrangements, proportions, and with other elements, materials, and components without departing from the spirit or essential characteristics of the present invention. Other variations and changes can be made to the embodiments disclosed herein without departing from the spirit or essential characteristics of the present invention.
