Description
Technical Field
[0001] The utility model relates to the technical field of automobile parts molds, in particular to a forming mold for an automobile sill support plate. Background Art
[0002] An automobile sill support plate, usually referred to as a sill beam or a sill panel, is a key component in the automobile body structure. The sill beam is a cross beam under the car door, located on the side of the vehicle body, connecting the front and rear parts of the vehicle body. It not only plays a decorative role, but more importantly, it undertakes the important responsibilities of enhancing the strength of the vehicle body structure, protecting the safety of passengers, and preventing the external environment from causing wear to the bottom of the vehicle body. The forming mold for an automobile sill support plate is a high-precision and high-strength mold, which is designed and manufactured according to the shape, size and performance requirements of the sill support plate. The mold processes raw materials into qualified sill support plates through processes such as injection molding, stamping, and rolling. It is one of the processes for manufacturing automobile sill support plates. The stamped plates will be lifted and unloaded by the blanking cylinder set in the mold and conveyed to the next process through a conveyor belt.
[0003] Due to the long-term use of the mold during the stamping process, its surface will gradually wear, resulting in a reduced contact area between the mold and the sheet metal and uneven pressure distribution, thus generating burrs during the stamping process. When the preliminarily formed workpieces in the mold are blanked, they will collide and rub against each other. During the mutual friction process of the workpieces, scratches, indentations or wear and other damages are likely to occur on the surface. These damages not only affect the appearance quality of the workpieces, but may also affect their accuracy and the reliability of subsequent use. And the large impact force causes the internal stress of its material to increase rapidly. When the stress exceeds the yield strength of the material, the workpiece will deform. Summary of the Utility Model
[0004] The purpose of the utility model is to provide a forming mold for an automobile sill support plate to solve the problems raised in the above background art.
[0005] In order to achieve the above purpose, the utility model adopts the following technical solutions:

[0013] Preferably, a notch is arranged on the slider, and the notch of the slider is divided into three sections, which are respectively a symmetric horizontal section one, a horizontal section two close to the guide rail, and a symmetric inclined section.
[0014] Preferably, the telescopic component further includes a support rod, the support rods are symmetrically arranged on one side of the bracket close to the blanking plate, and a connecting plate is connected to one side section of the support rod far from the bracket.
[0015] Preferably, sliding rods are symmetrically and slidably penetrated through the connecting plate, elastic members are sleeved on the outer surfaces of the sliding rods and are limited by the protrusions on the outer surfaces of the sliding rods and the connecting plate.
[0016] Preferably, a roller is rotatably arranged on one side of the sliding rod close to the slider, and the outer surface of the roller is mutually attached to the notch of the slider.

[0018] Preferably, the groove is slidably connected to the stop block.
[0019] Compared with the prior art, the utility model has the following beneficial effects:
[0020] Through the intermittent telescoping of the telescopic component, the workpieces that have been stamped and cooled are intermittently conveyed, avoiding the deformation caused by the large stress generated by the impact between the workpieces, reducing the defective products caused by the deformation, improving the qualified rate of the products, and the intermittent conveying method makes the conveying of the workpieces more orderly, avoiding the production interruption caused by the accumulation or chaos of the workpieces, and ensuring the continuity and stability of the production.
[0021] By sliding the stoppers in the sliding grooves, workpieces of different sizes can be accommodated, enabling the forming die to be widely used in the production of automotive sill support plates of various specifications, greatly improving the versatility of the equipment.

The stoppers can limit and guide the workpieces, keeping the workpieces in a stable position and direction during the conveying process, avoiding situations such as deviation and skew, and improving the production accuracy and quality.
[0022] The sliding of the stoppers in the grooves is horizontal, while the blanking of the workpieces after stamping and cooling is longitudinal. Since the sliding direction of the stoppers is perpendicular to the blanking direction of the workpieces, the workpieces will not exert a lateral force on the stoppers during blanking, effectively avoiding the displacement of the stoppers caused by workpiece blanking. This ensures that the stoppers can always remain in the preset position and stably play the role of limiting. BRIEF DESCRIPTION OF THE DRAWINGS

The term "one" should not be construed as a limitation on the quantity. Embodiment
[0033] Please refer to Figures 1-4 , a forming die for an automotive sill support plate member, comprising: an upper bottom plate 1 and a lower bottom plate 2. Upper die 3 and lower die 4 are respectively arranged on the opposite surfaces of the upper bottom plate 1 and the lower bottom plate 2. The upper bottom plate 1 and the lower bottom plate 2 respectively carry the upper die 3 and the lower die 4 and are fixedly connected to the upper die 3 and the lower die 4. After the upper die 3 and the lower die 4 are buckled, a casting cavity is formed. A blanking drive is arranged in the casting cavity to intermittently lift and blank the workpiece after stamping and cooling.
[0034] A forming die for an automotive sill support plate member further comprises: a blanking plate 5. The blanking plate 5 is arranged on the lower die 4 at equal intervals. A bracket 6 is arranged above the blanking plate 5. A telescopic assembly is arranged on one side of the bracket 6 close to the blanking plate 5. By intermittently telescoping the telescopic assembly, the workpieces that have been stamped and cooled are intermittently conveyed, avoiding deformation caused by large stresses generated by the impact between workpieces, reducing defective products caused by deformation, improving the qualified rate of products. The intermittent conveying method makes the conveying of workpieces more orderly, avoiding production interruption caused by workpiece accumulation or chaos, and ensuring the continuity and stability of production.
[0035] An automotive sill support plate forming die further includes: a connecting bar 14. The connecting bar 14 is arranged below the bracket 6. A stop block 16 is arranged on the connecting bar 14, which cooperates with the telescopic component for intermittent blanking and has adjustable spacing. The stop block 16 can be freely adjusted according to the workpiece size, improving the applicability of the equipment. After the spacing of the stop block 16 is adjusted appropriately, it can better cooperate with the telescopic component for workpiece conveying. The stop block 16 can limit and guide the workpiece, keeping the workpiece in a stable position and direction during the conveying process, avoiding situations such as deviation and skew, and improving the production precision and quality.
[0036] Among them, the bottom of the bracket 6 is fixedly connected to the lower bottom plate 2. The blanking plate 5 is divided into an inclined section and a horizontal section. The horizontal section of the blanking plate 5 is set as a conveyor belt. The inclined section of the blanking plate 5 is designed so that the workpiece after stamping and cooling can smoothly slide down to the horizontal section under the action of gravity. This natural sliding method reduces damage to the workpiece and also improves the blanking efficiency. The horizontal section of the blanking plate 5 is set as a conveyor belt, which can realize continuous conveying of the workpiece. The speed of the conveyor belt can be adjusted according to production requirements to ensure that the workpiece can be timely conveyed to the next process.
[0037] Furthermore, the telescopic component includes a guide rail 7. The guide rail 7 is fixedly arranged on one side of the bracket 6 close to the blanking plate 5. A slider 8 is slidably connected to the outer surface of the guide rail 7. Among them, a notch is arranged on the slider 8. The notch of the slider 8 is divided into three sections, which are respectively the horizontally symmetric first section at both ends, the horizontally second section close to the guide rail 7, and the symmetric inclined section. An external pushing cylinder is connected to the slider 8 to cause it to slide on the guide rail 7. The guide rail 7 is fixedly arranged on one side of the bracket 6 close to the blanking plate 5, providing a stable linear motion track for the slider 8. Under the action of the external pushing cylinder, the slider 8 can perform precise linear reciprocating motion along the guide rail 7, ensuring the accuracy and reliability of the telescopic action.
[0038] It is worth mentioning that the telescopic component further includes a support rod 9. The support rod 9 is symmetrically arranged on one side of the bracket 6 close to the blanking plate 5. A connecting plate 10 is connected to the side section of the support rod 9 far from the bracket 6. A sliding rod 11 is symmetrically and slidably connected through the connecting plate 10. Elastic members 12 are sleeved on the outer surfaces of the sliding rods 11 and are limited by the protrusions on the outer surfaces of the sliding rods 11 and the connecting plate 10. A roller 13 is rotatably arranged on the side of the sliding rod 11 close to the slider 8. The outer surface of the roller 13 is in mutual contact with the notch of the slider 8. When the external pushing cylinder of the slider 8 drives the slider 8 to continuously reciprocate on the guide rail 7, the slider 8 will squeeze the roller 13 on the sliding rod 11 through the notch to cause the sliding rod 11 to slide up and down. When the roller 13 at the top of one sliding rod 11 is located in the horizontally second section close to the guide rail 7, the roller 13 at the top of the other sliding rod 11 is located in the horizontally symmetric first section at both ends, so that the telescopic component intermittently buffers and blanks the workpiece, avoiding mutual rubbing between workpieces.
[0039] Furthermore, one end of the sliding rod 11 away from the slider 8 is fixedly connected to the connecting bar 14, and a groove 15 is provided at the bottom of the connecting bar 14. The groove 15 is slidably connected to the stopper 16. When the size of the workpiece is small, the distance between the stoppers 16 can be reduced by sliding the stopper 16 in the groove 15. When the size of the workpiece is large, the distance between the stoppers 16 can be increased by sliding the stopper 16 in the groove 15. Different sizes of workpieces can be adapted, enabling the forming die to be widely used in the production of automotive sill support plates of various specifications, greatly improving the versatility of the equipment.
[0040] It is further worth noting that the sliding of the stopper 16 in the groove 15 is horizontal, while the blanking of the workpiece after stamping and cooling is longitudinal. Since the sliding direction of the stopper 16 is perpendicular to the blanking direction of the workpiece, no lateral force is generated on the stopper 16 during workpiece blanking, effectively avoiding the displacement of the stopper 16 caused by workpiece blanking. This ensures that the stopper 16 can always remain in the preset position and stably play the limiting role. In addition, there is a certain resistance when the stopper 16 slides in the groove 15, but this resistance does not prevent the operator from adjusting the position of the stopper 16. The operator can accurately slide the stopper 16 to the required position according to the size of the workpiece, and due to the existence of the resistance, the stopper 16 will not move easily after adjustment, facilitating the operation and adjustment process.
[0041] It should be noted that in this article, relational terms such as first and second are only used to distinguish one entity or operation from another entity or operation, and do not necessarily require or imply any actual relationship or order between these entities or operations. Moreover, the term "comprising", "including" or any other variation thereof is intended to cover non-exclusive inclusion, so that a process, method, article or device including a series of elements includes not only those elements but also other elements not explicitly listed, or elements inherent to such process, method, article or device. Without further limitation, an element defined by the statement "including a..." does not exclude the existence of additional identical elements in the process, method, article or device including the said element.
[0042] Those skilled in the art should understand that the embodiments of the present invention described above and shown in the drawings are only examples and do not limit the present invention. The object of the present invention has been fully and effectively achieved. The functions and structural principles of the present invention have been demonstrated and explained in the embodiments. Without departing from the said principles, the embodiments of the present invention can have any deformation or modification.
