Description

Technical Field

[0001] This utility model relates to the field of stamping die technology, specifically to a stamping die for an automotive seat side panel. Background Technology

[0002] Stamping is a pressure processing method that uses a die mounted on a press to apply pressure to a material at room temperature, causing it to separate or plastically deform, thereby obtaining the desired part. Car seat side panels are support plates installed on both sides of a car seat to support and wrap the car seat.

[0003] According to a publicized automotive seat side panel stamping die (publication number: CN217700989U), the above application uses the switching on and off of the electromagnet block of the drive mechanism to achieve the contact and separation of the first and second lower dies. This achieves the limiting of the automotive side panel to be processed during stamping and, after stamping, when the first and second lower dies quickly separate, the automotive side panel body located in the limiting grooves of the two dies falls under its own gravity and is automatically unloaded from the die through the unloading port. This achieves the automatic unloading operation of the processed automotive side panel, thereby eliminating the need for manual material handling and avoiding the safety hazards associated with manual material handling, and improving stamping efficiency.

[0004] However, in actual use, the existing seat side panels are often asymmetrical, causing the side panels to have different weights on the two sets of molds. When the center of gravity of the side panel is completely on one set of molds, the two sets of molds separate, and the side panel will stay on the mold where the center of gravity is located, making it difficult for the side panel to fall off. It needs to be manually removed, which wastes a lot of manpower and time, reduces the efficiency of the stamping mold, and also brings safety hazards to users due to manual material handling. In view of this, we propose a stamping mold for automotive seat side panels. Utility Model Content

[0005] The purpose of this utility model is to provide a stamping die for automotive seat side panels to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a stamping die for an automotive seat side panel, comprising a housing, a hydraulic rod fixedly connected to the upper outer wall of the housing, the output end of the hydraulic rod penetrating the outer wall of the housing and fixedly connected to a pressure plate, a limit rod fixedly connected to the outer wall of the pressure plate, a spring fixedly connected to the outer wall of the pressure plate, a fitting plate fixedly connected to the lower outer wall of the spring, a support seat rotatably connected to the inner wall of the housing, a shallow die plate slidably connected to the upper outer wall of the support seat, a deep die plate slidably connected to the upper outer wall of the support seat, electric push rods fixedly connected to the ends of the deep die plate and the shallow die plate that are far apart from each other, and an ejection assembly provided inside the support seat, the ejection assembly comprising:

[0007] A slide groove is formed on the upper outer wall of the support base. A slide rod is fixedly connected to the inner wall of the slide groove. A slider is fixedly connected to the lower outer wall of both the deep mold plate and the shallow mold plate. The slider is sleeved on the outer wall of the slide rod. A hinge plate is hinged to the lower outer wall of the slider.

[0008] An ejector plate is hinged to the lower outer wall of a hinge plate. A through slot is provided on the outer wall of the support base. An ejector rod is fixedly connected to one end of the ejector plate near the slot. A positioning rod is slidably connected through the outer wall of the ejector plate.

[0009] Preferably, the outer casing is provided with a feeding assembly, which includes a rotating shaft fixedly connected to the outer wall of the support base. A motor is fixedly connected to the outer wall of the outer casing, and the output end of the motor is fixedly connected to the rotating shaft. A ramp is fixedly connected to the outer wall of the outer casing, and a limit block is fixedly connected to the inner wall of the outer casing, so that the motor can drive the support base to tilt, causing the side plate to tilt, so that when the ejector rod ejects the side plate, the side plate can slide down the ramp.

[0010] Preferably, the width of the limiting block is half the width of the support base, the upper outer wall of the limiting block contacts the lower outer wall of the support base, and the upper end of the inclined platform contacts the upper outer wall of the support base, so that the limiting block can limit the support base, and the deep mold plate and the shallow mold plate are parallel to the pressure plate at the same time, so that the mold is more stable when it is stamped. After the stamping is completed, the motor causes the support base to rotate so that the support base contacts the upper outer wall of the inclined platform.

[0011] Preferably, both the deep mold plate and the shallow mold plate have through-hole limiting grooves on their outer walls. The size of the limiting grooves matches the limiting rod. The limiting rod slides through the pressure plate and is connected to the inner wall of the limiting groove. The spring is sleeved on the outer wall of the limiting rod, so that the bonding plate can be completely bonded to the upper outer wall of the shallow mold plate and the deep mold plate.

[0012] Preferably, the outer walls of the shallow mold plate and the deep mold plate are attached to each other at their closest points, and the slot has a support seat on the outer wall near the attachment point of the shallow mold plate and the deep mold plate. When the shallow mold plate and the deep mold plate separate, the slider drives the hinge plate to make the ejector plate drive the ejector rod to rise, so that the ejector rod can push the side plate away from the mold.

[0013] Preferably, a collar is fixedly connected to one end of the ejector plate near the positioning rod. The positioning rod is fixedly connected to the inner wall of the support base. The collar is sleeved on the outer wall of the positioning rod, so that the ejector plate can move along the positioning rod. When the ejector rod can be accurately inserted into the slot, the ejector rod can demold the side plate after the deep mold plate and the shallow mold plate are opened.

[0014] Preferably, the fixed ends of both sets of electric actuators are fixedly connected to the outer wall of the support base, and the output ends of the two sets of electric actuators are fixedly connected to the deep mold plate and the shallow mold plate respectively, so that after the pressure plate punches the side plate, the electric actuators drive the deep mold plate and the shallow mold plate to separate, so that the side plate after punching can be ejected by the ejector rod.

[0015] Compared with the prior art, the present invention provides a stamping die for automotive seat side panels, which has the following advantages:

[0016] 1. The stamping die for the side panel of the car seat moves by moving the shallow die plate and the deep die plate, which drives the slider to move on the slide rod, causing the hinge plate to rotate and drive the ejector plate to move along the positioning rod, so that the ejector rod can be ejected from the slot, and the ejector rod can push the side panel away from the die plate, so that the side panel will not stay on the die plate where the center of gravity is located, thus making the side panel easy to demold.

[0017] 2. This automotive seat side panel stamping die uses a limiting block to limit the support base, ensuring that both the deep and shallow die plates are parallel to the pressure plate. This makes the die more stable during stamping. After stamping, the motor can tilt the support base via a rotating shaft, causing the side panel to tilt. This allows the side panel to slide down the inclined platform when the ejector rod ejects the side panel, ensuring a smooth landing and preventing damage from direct impact.

[0024] like Figures 1-5 As shown, this utility model provides a technical solution: a stamping die for a car seat side panel, including a housing 1, a hydraulic rod 2 fixedly connected to the upper outer wall of the housing 1, the output end of the hydraulic rod 2 penetrating the outer wall of the housing 1 and fixedly connected to a pressure plate 3, a limit rod 4 fixedly connected to the outer wall of the pressure plate 3, a spring 5 fixedly connected to the outer wall of the pressure plate 3, a bonding plate 6 fixedly connected to the lower outer wall of the spring 5, a support base 10 rotatably connected to the inner wall of the housing 1, a shallow die plate 7 slidably connected to the upper outer wall of the support base 10, a deep die plate 8 slidably connected to the upper outer wall of the support base 10, and electric push rods 9 fixedly connected to the ends of the deep die plate 8 and the shallow die plate 7 that are far apart from each other. An ejection assembly 11 is provided inside the support base 10, the ejection assembly 11 including:

[0025] The slide 111 is formed on the upper outer wall of the support base 10. The inner wall of the slide 111 is fixedly connected to the slide rod 112. The lower outer walls of the deep mold plate 8 and the shallow mold plate 7 are both fixedly connected to the slider 113. The slider 113 is sleeved on the outer wall of the slide rod 112. The lower outer wall of the slider 113 is hinged to the hinge plate 114.

[0026] Ejector plate 115 is hinged to the lower outer wall of hinge plate 114. The outer wall of support base 10 has a through slot 116. An ejector rod 117 is fixedly connected to one end of ejector plate 115 near slot 116. A positioning rod 118 is slidably connected through the outer wall of ejector plate 115.

[0027] In one embodiment of this utility model, a groove 111 is formed on the upper outer wall of the support base 10, and a slide rod 112 is fixedly connected to the inner wall of the groove 111. A slider 113 is fixedly connected to the lower outer wall of both the deep mold plate 8 and the shallow mold plate 7. The slider 113 is sleeved on the outer wall of the slide rod 112, and a hinge plate 114 is hinged to the lower outer wall of the slider 113.

[0028] In one embodiment of the present invention, the ejector plate 115 is hinged to the lower outer wall of the hinge plate 114, the outer wall of the support base 10 is provided with a through slot 116, the end of the ejector plate 115 near the slot 116 is fixedly connected to an ejector rod 117, and the outer wall of the ejector plate 115 is slidably connected to a positioning rod 118.

[0029] In addition, the inner wall of the outer shell 1 is provided with a feeding assembly 12, which includes a rotating shaft 121. The rotating shaft 121 is fixedly connected to the outer wall of the support base 10. A motor 122 is fixedly connected to the outer wall of the outer shell 1. The output end of the motor 122 is fixedly connected to the rotating shaft 121. An inclined platform 123 is fixedly connected to the outer wall of the outer shell 1. A limit block 124 is fixedly connected to the inner wall of the outer shell 1, so that the motor 122 can drive the support base 10 to tilt, causing the side plate to tilt. This allows the side plate to slide down the inclined platform 123 when the ejector rod 117 ejects the side plate, so that the side plate can land smoothly and prevent the side plate from being damaged by landing directly.

[0030] In this embodiment of the utility model, the width of the limiting block 124 is half the width of the support base 10. The upper outer wall of the limiting block 124 contacts the lower outer wall of the support base 10, and the upper end of the inclined platform 123 contacts the upper outer wall of the support base 10, so that the limiting block 124 can limit the support base 10, so that the deep mold plate 8 and the shallow mold plate 7 are parallel to the pressure plate 3 at the same time, making the mold more stable when it is stamped. After the stamping is completed, the motor 122 causes the support base 10 to rotate so that the support base 10 contacts the upper outer wall of the inclined platform 123, so that the side plate can slide down from the inclined platform 123.

[0031] In the embodiments of this utility model, both the outer walls of the deep mold plate 8 and the shallow mold plate 7 are provided with through-hole limiting grooves. The size of the limiting grooves matches the limiting rod 4. The limiting rod 4 slides through the pressure plate 3 and is connected to the inner wall of the limiting groove. The spring 5 is sleeved on the outer wall of the limiting rod 4, so that the bonding plate 6 can be completely bonded to the upper outer wall of the shallow mold plate 7 and the deep mold plate 7, so that the pressure plate 3 can accurately punch the upper side plate of the mold.

[0032] In an embodiment of this utility model, the outer walls of the shallow mold plate 7 and the deep mold plate 8 are fitted together at their closest points. The slot 116 has a support seat 10 on the outer wall near the fitting point of the shallow mold plate 7 and the deep mold plate 8. When the shallow mold plate 7 and the deep mold plate 8 separate, the slider 113 drives the hinge plate 114 to cause the ejector plate 115 to drive the ejector rod 117 to rise, so that the ejector rod 117 can push the side plate away from the mold. Thus, the side plate can automatically leave the mold plate where the center of gravity is located without manual demolding.

[0033] In an embodiment of this utility model, a collar is fixedly connected to one end of the ejector plate 115 near the positioning rod 118. The positioning rod 118 is fixedly connected to the inner wall of the support base 10. The collar is sleeved on the outer wall of the positioning rod 118, so that the ejector plate 115 can move along the positioning rod 118. When the ejector rod 117 can be accurately inserted into the slot 116, the ejector rod 117 can demold the side plate after the deep mold plate 8 and the shallow mold plate 7 are opened, so that the side plate will not stay on the mold plate where the center of gravity is located.

[0034] In the embodiments of this utility model, the fixed ends of the two sets of electric push rods 9 are fixedly connected to the outer wall of the support base 10, and the output ends of the two sets of electric push rods 9 are fixedly connected to the deep mold plate 8 and the shallow mold plate 7 respectively. After the pressure plate 3 stamps the side plate, the electric push rods 9 drive the deep mold plate 8 and the shallow mold plate 7 to separate, so that the stamped side plate can be ejected by the ejector rod 117 and separated from the deep mold plate 8 and the shallow mold plate 8, without the need for manual demolding.

[0035] In this invention, during use, the raw material is placed in the grooves on the mating shallow mold plate 7 and deep mold plate 8. The hydraulic rod 2 pushes the pressure plate 3 through the mating plate 6 to press the raw material into a side plate. Then, the electric push rod 9 moves the shallow mold plate 7 and deep mold plate 8 in a direction away from each other. At this time, the movement of the shallow mold plate 7 and deep mold plate 8 drives the slider 113 to move on the slide rod 112, causing the hinge plate 114 to drive the ejector plate 115 to move along the positioning rod 118, pushing the ejector rod 117 out of the slot 116, so that the ejector rod 117 can push the side plate from... The side plate is separated from the mold plate, so that it will not stay on the mold plate where the center of gravity is located, thus making it easy to demold. The limiting block 124 can limit the support base 10, so that the deep mold plate 8 and the shallow mold plate 7 are parallel to the pressure plate 3 at the same time, making the mold more stable when it is stamped. After the stamping is completed, the motor 122 can drive the support base 10 to tilt through the rotating shaft 121, so that the side plate tilts, so that when the ejector rod 117 ejects the side plate, the side plate can slide down the inclined platform 123, so that the side plate can land smoothly and prevent the side plate from being damaged by landing directly.

[0036] The present invention has been described in detail above. However, modifications or improvements can be made to it, which will be obvious to those skilled in the art. Therefore, any modifications or improvements that do not depart from the spirit of the present invention are within the protection scope of the present invention.
