Description

Technical Field

[0001] This utility model relates to the field of stripping technology, and in particular to a non-destructive stripping device for automobile bracket molds. Background Technology

[0002] In the automotive manufacturing industry, automotive brackets are key components, and their molding quality directly affects the overall performance and safety of a vehicle. Traditional automotive bracket molds have revealed numerous problems during the production process, which urgently need to be addressed.

[0003] In terms of demolding, traditional mold ejection methods are rather crude. Some molds rely on manual prying to remove the support, which is not only inefficient but also easily causes scratches, bumps, and other damage to the support surface, affecting the product's appearance and structural strength. Other molds, while employing mechanical ejection, lack a reasonable linkage mechanism and auxiliary measures, resulting in high friction between the support and the mold's inner wall during demolding, which can easily lead to support deformation or even damage. Utility Model Content

[0004] The purpose of this invention is to provide a non-destructive unloading device for automobile bracket molds to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution, which includes a lower mold body, a mold groove on the lower mold body, guide pillars at the four corners of the top of the lower mold body, a top plate on the top of several guide pillars, a pressing and releasing component on the top plate, an installation groove inside the lower mold body, support plates symmetrically arranged on both sides of the installation groove, and a material ejection component inside the installation groove.

[0006] As a preferred embodiment of this utility model, the pressing and releasing assembly includes a pair of telescopic cylinders disposed on the top of the top plate. The telescopic rods of the telescopic cylinders pass through the top plate, and a connecting plate is disposed on the top of the telescopic rods. The two connecting plates are connected to the pressure plate by several bolts. An upper mold body is disposed at the bottom of the pressure plate corresponding to the position of the mold groove. Sliding sleeves are disposed on the pressure plate corresponding to the positions of several guide pillars, and the guide pillars are disposed inside the sliding sleeves.

[0007] The pressure plate is symmetrically provided with U-shaped connectors on both sides, and the two support plates are symmetrically provided with opposing blocks. The opposing block is provided with a first inclined surface at one end in the mounting groove. The opposing block is provided with a U-shaped connector at the tail. The U-shaped connectors on the same side and the U-shaped connectors on the same side are movably connected by a connecting rod.

[0008] In a preferred embodiment of this utility model, the top material assembly includes a T-shaped block disposed between two opposing top blocks. A second inclined surface is provided on both the left and right sides of the T-shaped block, and the second inclined surface fits into the first inclined surface. Several through holes are provided in the model groove. Several top pillars are provided on the top of the T-shaped block corresponding to the positions of the through holes. First sliding grooves are provided on the front and rear inner walls of the mounting groove. Sliding blocks are symmetrically arranged on the front and rear sides of the T-shaped block, and the sliding blocks are disposed within the first sliding grooves.

[0009] The top material assembly also includes an air pump installed on the outer wall of the lower mold body. The output end of the air pump is located in the mounting groove, and its output end is connected to the T-shaped block through a hose. Several air holes are opened on the top of the T-shaped block.

[0010] As a preferred embodiment of this utility model, the outer sides of the four corners of the groove of the model are provided with right-angled edges for plate positioning, and slots are provided at the bottom of the pressure plate corresponding to several right-angled edges for plate positioning.

[0011] As a preferred embodiment of this utility model, the mounting groove and the support plate are both provided with slide rails, the bottom of the top block is provided with a second slide groove corresponding to the position of the slide rail, the slide rail is set in the second slide groove, and the bottom of the T-shaped block is provided with several tension springs, the bottom end of the tension springs is set on the slide rail.

[0012] Compared with the prior art, the above-mentioned technical solution of this utility model has the following beneficial technical effects:

[0013] 1. After the stamping process, the air pump delivers air to the T-shaped block through a hose. The airflow ejected from the air hole forms a gap between the support and the inner wall of the mold groove, reducing the friction between them. When the telescopic rod retracts, the pressure plate drives the connecting rod to move the top block inward. Through the cooperation between the top block and the slope of the T-shaped block, the T-shaped block is pushed up. The top column lifts the support to complete the unloading. The entire unloading process relies on the ingenious linkage of the mechanical structure and the airflow assistance. No manual intervention is required, the unloading efficiency is high, and damage to the support can be avoided.

[0014] 2. This utility model uses guide posts at the four corners of the top of the lower mold body to cooperate with the sliding sleeves on the pressure plate to provide precise guidance for the up and down movement of the pressure plate. During the process of the pressure plate being pressed down by the telescopic cylinder, the sliding sleeves slide smoothly along the guide posts to prevent the pressure plate from shaking or shifting, so that the upper mold body can evenly apply pressure to the plate, ensuring that the plate is evenly stressed in the mold groove, resulting in better molding effect.

Detailed Implementation

[0024] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to specific embodiments and accompanying drawings. It should be understood that these descriptions are merely exemplary and not intended to limit the scope of this utility model. Furthermore, descriptions of well-known structures and technologies are omitted in the following description to avoid unnecessarily obscuring the concept of this utility model.

[0025] like Figure 1 - Figure 8 As shown, the present invention proposes a non-destructive stripping device for an automobile bracket mold, which includes a lower mold body 1, which is the basic component of the entire mold structure. The lower mold body 1 has a mold groove 12 for forming sheet metal. Guide columns 10 are vertically arranged at the four corners of the top of the lower mold body 1. These guide columns 10 play a role in guiding and stabilizing the movement of other components. A top plate 11 is fixedly arranged on the top of several guide columns 10, and the top plate 11 provides an installation base for other components.

[0026] The press-and-release assembly 2 is mainly used for stamping and demolding of sheet metal. A pair of telescopic cylinders 20 are symmetrically arranged on the top of the top plate 11. The telescopic rod of the telescopic cylinder 20 can extend downward through the top plate 11. A connecting plate 29 is connected to the top of the telescopic rod. The two connecting plates 29 are then firmly connected to the pressure plate 21 by several bolts. This connection method allows the telescopic cylinder 20 to stably drive the pressure plate 21 to move up and down. An upper mold body 210 is arranged at the bottom of the pressure plate 21 corresponding to the mold groove 12. The upper mold body 210 directly acts on the sheet metal. When the pressure plate 21 presses down, it presses the sheet metal into the mold groove 12 to achieve forming. In order to ensure the stability of the pressure plate 21 during the up and down movement, a sliding sleeve 22 is arranged at the position of several guide posts 10 on the pressure plate 21. The guide posts 10 are movably arranged in the sliding sleeve 22. The sliding sleeve 22 and the guide posts 10 adopt a clearance fit, which can ensure the smooth sliding of the pressure plate 21 and play a precise guiding role.

[0027] U-shaped connectors 23 are symmetrically arranged on both sides of the pressure plate 21, and counter-blocks 25 are symmetrically arranged on the two support plates 16. One end of the counter-block 25 located in the mounting groove 15 is provided with a first inclined surface 27, and the tail end is provided with a U-shaped connector 26. The U-shaped connectors 23 and 26 on the same side are movably connected by a connecting rod 24. The two ends of the connecting rod 24 are connected to the U-shaped connectors 23 and 26 by movable connecting parts such as pins, so that when the pressure plate 21 moves, the counter-blocks 25 can be driven to perform corresponding actions through the connecting rod 24.

[0028] The ejector assembly 3 is mainly responsible for the demolding operation after stamping. A T-shaped block 30 is set between the two ejector blocks 25. A second ramp surface 32 is set on both the left and right sides of the T-shaped block 30. The second ramp surface 32 fits into the first ramp surface 27 of the ejector block 25. When the ejector block 25 moves under the action of the connecting rod 24, the T-shaped block 30 can be pushed up and down through the cooperation of the two ramp surfaces. Several through holes 14 are opened in the mold groove 12. Several top posts 31 are set on the top of the T-shaped block 30 corresponding to the positions of the through holes 14. The mounting groove 15... The front and rear inner walls are provided with first sliding grooves 18. Slider blocks 33 are symmetrically arranged on the front and rear sides of the T-shaped block 30. The sliders 33 are set in the first sliding grooves 18. This cooperation between the sliders 33 and the sliding grooves restricts the movement trajectory of the T-shaped block 30, so that it can only move up and down in the vertical direction. At the same time, several tension springs 37 are provided at the bottom of the T-shaped block 30. The bottom end of the tension springs 37 is fixed on the slide rail 17 that is shared by the mounting groove 15 and the support plate 16. The tension springs 37 are always in a stretched state, providing downward tension for the T-shaped block 30.

[0029] An air pump 34 is provided on the outer wall of the lower mold body 1. The output end of the air pump 34 is located in the mounting groove 15, and its output end is connected to the T-block 30 through a hose 35. Several air holes 36 are opened on the top of the T-block 30. The air pump 34 delivers air to the T-block 30 through the hose 35 and sprays it out from the air holes 36. This is used to create a gap between the support and the inner wall of the mold groove 12 during demolding, so as to facilitate demolding.

[0030] On the outer sides of the four corners of the groove of the model groove 12, right-angled edges 13 for positioning the plate are welded on to position the plate before processing. Slots 211 are provided at the bottom of the pressure plate 21 corresponding to the positions of several right-angled edges 13 for positioning the plate. When the pressure plate 21 is pressed down, the right-angled edges 13 for positioning the plate can be inserted into the slots 211, further ensuring the relative position accuracy of the pressure plate 21 and the lower mold 1 during the pressing process.

[0031] The slide rail 17 extends from one side of the support plate 16 through the mounting groove 15 to another support plate 16. A second slide groove 28 is provided at the bottom of the top block 25 corresponding to the position of the slide rail 17. The slide rail 17 is set in the second slide groove 28. This connection method allows the top block 25 to move smoothly left and right along the slide rail 17 on the support plate 16, ensuring its cooperative working effect with other components.

[0032] During equipment operation, the sheet material to be processed must first be placed stably in the positioning area formed by several right-angled edges 13 of the sheet material positioning. This right-angled edge design can ensure the rapid positioning of the sheet material and provide a stable foundation for subsequent processing. After it is properly placed, the telescopic cylinder 20 is started. The telescopic cylinder 20 starts working and pushes out the telescopic rod. The telescopic rod will push the pressure plate 21 to move downward. At this time, the upper mold body 210 connected to the pressure plate 21 plays a role in pressing the sheet material into the mold groove 12 to complete the forming process of the sheet material.

[0033] During the pressing process of the pressure plate 21, the linkage mechanism between the mechanical structures starts to operate. The connecting rod 24 connected to the pressure plate 21 will push the top block 25 to move towards the outside of the mounting groove 15. After the top block 25 moves, the T-shaped block 30 moves downward under the action of the tension spring 37, so that the top surface of the top column 31 is at the same level as the bottom surface of the mold groove 12. This can effectively avoid the top column 31 from interfering with the forming of the bracket and ensure the forming quality.

[0034] After the stamping process is completed, the telescopic cylinder 20 begins to operate in reverse, retracting the telescopic rod. At the same time, the air pump 34 starts, delivering air to the T-block 30 through the hose 35. The air is then ejected at high speed from several air holes 36 on the T-block 30. This airflow creates a gap between the bracket and the inner wall of the mold groove 12, reducing the friction between them and facilitating subsequent demolding. As the telescopic rod continues to retract, the pressure plate 21 drives the connecting rods 24 on both sides, causing the two opposing blocks 25 to move synchronously into the mounting groove 15. Since the first slope surface 27 of the opposing block 25 and the second slope surface 32 of the T-block 30 cooperate with each other, the movement of the opposing block 25 will push the T-block 30 upward. The T-block 30 then lifts the formed bracket through the top column 31, completing the entire demolding operation.
