Description

Technical Field

[0001] This utility model relates to the field of mold technology, specifically to an ejection device for a back plate mold of an air conditioning compressor for new energy vehicles. Background Technology

[0002] The backplate of a new energy vehicle air conditioning compressor is a crucial component. Located at one end of the motor housing, it seals the opening in the motor housing. The backplate is typically an annular plate with a through-hole for the motor shaft to pass through. A sealing structure surrounds the through-hole to prevent airflow leakage. The backplate forms a sealed gap with the volute housing to support the impeller. Additionally, the backplate may also have air inlets to guide airflow into the air passage, enabling functions such as pressure relief at the back of the pressure roller.

[0003] Existing automotive air conditioning compressor backplates are mostly circular in shape with a pivot hole in the center. When stamped into a backplate, they form a shape similar to a circular cover plate. As a result, the backplate gets stuck on the punch, making it inconvenient to unload. Generally, it is unloaded manually, which is not only time-consuming and labor-intensive but also reduces work efficiency. Therefore, a new type of ejection device for the mold of the backplate of the air conditioning compressor for new energy vehicles is needed to solve the above problems. Utility Model Content

When it is stamped into a back plate, it will form a shape similar to a circular cover plate. Therefore, the back plate will stick to the punch and be inconvenient to unload. Generally, it is unloaded manually, which is not only time-consuming and labor-intensive, but also reduces work efficiency.

[0011] As a preferred embodiment of the above technical solution, a side plate is fixedly connected to the side end of the mounting platform, and the side plate is fixed to the top of the base by bolts.

[0019] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention.

[0020] like Figures 1-4 As shown, this utility model provides a technical solution: a back panel mold ejection device for a new energy vehicle air conditioning compressor, including a base 1, a bracket 101 fixedly installed at the top of the base 1, a pressing mold 2 provided at the top of the bracket 101, an mounting platform 3 installed at the top of the base 1, a side plate 302 fixedly connected to the side end of the mounting platform 3, the side plate 302 being fixed to the top of the base 1 by bolts, a lower mold 4 provided at the top of the mounting platform 3, an ejection component 5 provided at the outer end of the lower mold 4, and two circular grooves 301 opened at the top of the mounting platform 3, the interior of the two circular grooves 301 being... A spring return assembly 6 is provided, and the ejection assembly 5 is connected to each spring return assembly 6. Through the cooperative arrangement of the ejection assembly 5 and the spring return assembly 6, after the back plate is stamped, there is no need for manual removal of the material. The entire ejection process is automatically completed by the spring 603, eliminating the need for manual material removal by reaching into the mold. This solves the problems of time-consuming, labor-intensive, and inefficient traditional manual material removal, significantly shortens the single production cycle, and improves the production efficiency of back plate stamping. At the same time, the ring plate 501 is sleeved on the outer end of the punch 401, which can be evenly stressed during ejection, avoiding deformation of the back plate due to uneven stress and ensuring the forming quality of the back plate.

[0021] As one implementation method in this embodiment, such as Figure 1 and Figure 2As shown, the pressing mold 2 includes a cylinder 201, which is fixedly installed on the top of the bracket 101. A fixing plate 202 is installed on the telescopic end of the cylinder 201. A pressure plate 203 is fixedly installed on the bottom end of the fixing plate 202 by bolts. A die 204 is fixedly connected to the bottom end of the pressure plate 203. A slot 205 is opened at the top of the inside of the die 204. Two pressure rods 206 are fixedly connected to the bottom end of the pressure plate 203. Several limiting rods 303 are fixedly connected to the top of the mounting platform 3. Each limiting rod 303 is inserted into the top of the pressure plate 203. A limiting plate 304 is fixedly connected to the top of each limiting rod 303. The lower mold 4 includes a punch 401, which is fixedly connected to the top of the mounting platform 3. The outer end is fixedly connected to a limiting ring 402, and the top of the punch 401 is fixedly connected to a plug rod 403. In practice, when the air conditioner compressor back panel is stamped, the mold alignment is prepared first. The punch 401 of the lower mold 4 at the top of the mounting platform 3 corresponds to the die 204 of the pressing mold 2. The plug rod 403 at the top of the punch 401 is aligned with the slot 205 inside the die 204. The limiting rod 303 at the top of the mounting platform 3 is inserted into the pressure plate 203 to guide the subsequent stamping. The cylinder 201 of the pressing mold 2 is started, and its telescopic end pushes the fixed plate 202, the pressure plate 203 and the die 204 to move down. The die 204 and the punch 401 close the mold, and the raw material is stamped to form an annular cover-shaped back panel, thereby realizing the stamping of the back panel.

[0022] As one implementation method in this embodiment, such as Figure 1 , Figure 3 and Figure 4As shown, the ejector assembly 5 includes a ring plate 501, which is sleeved on the outer end of the punch 401. Several anti-slip particles 502 are fixedly connected to the top of the ring plate 501. Connecting plates 503 are fixedly connected to both the left and right sides of the ring plate 501. The springback assembly 6 includes a round rod 601, which is fixedly connected to the bottom end of the connecting plate 503. The round rod 601 is inserted into a circular groove 301. A circular plate 602 is fixedly connected to the bottom end of the round rod 601. A spring 603 is fixedly connected to the bottom end of the circular plate 602. The bottom end of the spring 603 is fixedly connected to the bottom end of the circular groove 301. In practice, after the back plate is stamped, there is no need for manual removal of the material; the compressed spring 603... The spring rebounds under its own elastic force, pushing the circular plate 602, the circular rod 601 and the connecting plate 503 upward. The connecting plate 503 drives the ring plate 501 to move upward along the outer end of the punch 401. The top of the ring plate 501 directly lifts the back plate that is attached to the punch 401, so that the back plate is separated from the punch 401. The entire ejection process is automatically completed by the spring 603, without the need for manual material removal by reaching into the mold. This solves the problems of time-consuming, labor-intensive and inefficient traditional manual material handling, greatly shortens the single production cycle, and improves the efficiency of back plate stamping. At the same time, the ring plate 501 is sleeved on the outer end of the punch 401, so it can be evenly stressed during ejection, avoiding deformation of the back plate due to uneven stress and ensuring the forming quality of the back plate.

[0023] Working principle: During the stamping and forming of the air conditioner compressor back panel, the mold alignment is first completed. The punch 401 of the lower mold 4 at the top of the mounting platform 3 corresponds to the die 204 of the pressing mold 2. The insertion rod 403 at the top of the punch 401 is aligned with the slot 205 inside the die 204. The limiting rod 303 at the top of the mounting platform 3 is inserted into the pressure plate 203 to guide the subsequent stamping. The cylinder 201 of the pressing mold 2 is activated, and its telescopic end pushes the fixing plate 202, the pressure plate 203 and the die 204. As the die moves downward, the die 204 and the punch 401 close together to press the raw material and form an annular cover-shaped back plate. At the same time, the pressure rod 206 at the bottom of the pressure plate 203 moves downward to squeeze out the connecting plate 503 of the ejector assembly 5. The connecting plate 503 drives the ring plate 501 and the round rod 601 to move into the round groove 301. The round plate 602 at the bottom of the round rod 601 compresses the spring 603 until the ring plate 501 fits against the top of the limiting ring 402. After the stamping is completed, the cylinder 201 drives the die 204 to reset and move upward.

[0024] After the back plate is stamped, there is no need for manual removal of the material. The compressed spring 603 rebounds under its own elastic force, pushing the round plate 602, the round rod 601 and the connecting plate 503 upward. The connecting plate 503 drives the ring plate 501 to move upward along the outer end of the punch 401. The top of the ring plate 501 directly lifts the back plate that is attached to the punch 401, so that the back plate is separated from the punch 401. The entire ejection process is automatically completed with the help of the spring 603 rebound, without the need for manual material removal by reaching into the mold. This solves the problems of time-consuming, labor-intensive and inefficient traditional manual material removal, greatly shortens the single production cycle, and improves the production efficiency of back plate stamping. At the same time, the ring plate 501 is sleeved on the outer end of the punch 401, so it can be evenly stressed during ejection, avoiding deformation of the back plate due to uneven stress and ensuring the forming quality of the back plate.

[0025] If it is necessary to replace the lower die 4 and the pressing die 2 with different specifications, simply unscrew the bolts connecting the side plate 302 and the base 1 to remove the mounting table 3 and replace the punch 401. The replacement steps for the die 204 are the same, making the operation convenient. The anti-slip particles 502 at the top of the ring plate 501 can reduce the sliding between the back plate and the ring plate 501 during ejection, further ensuring the stability of ejection and providing convenience for subsequent back plate transfer. The overall device effectively ensures the continuity and efficiency of back plate stamping production.

[0026] The above embodiments are only used to illustrate the technical solution of this utility model, and are not intended to limit it.
