Description

Technical Field

[0001] This utility model relates to a mold base, specifically a mold base for stamping irregular metal parts. Background Technology

[0002] When processing irregularly shaped metal parts, corresponding stamping dies are required. After being processed by the stamping die, the parts can be formed into irregularly shaped metal parts that meet the standards. One of the important structures on the stamping die is the die base, which plays a supporting role for the entire die.

[0003] Existing die bases for stamping irregularly shaped metal parts have unreasonable designs and complex structures. They lack a buffering mechanism between the base and support plate, resulting in direct pressure application to the support plate and base during stamping. This causes mechanical stress to concentrate in a specific area, making the support plate or base prone to damage over time. Existing die bases also have poor pressure resistance, shortening their lifespan. Furthermore, slight wobble or random vibrations between the support plate and base affect the precision of the die base. Therefore, the inventors have improved the structure of the die base for stamping irregularly shaped metal parts. Utility Model Content

[0004] The purpose of this utility model is to provide a die holder for stamping irregularly shaped metal parts. This die holder has a simple structure and reasonable design. The bladder provided acts as a buffer between the plate and the base, reducing the impact of pressure on the base and plate, and making the die holder more capable of withstanding pressure. The guide mechanism provided on both sides of the bladder can guide the base and the plate, making the relative movement between the base and the plate more controllable, preventing shaking or disordered vibration, avoiding affecting the precision of the die holder, effectively dispersing mechanical stress, preventing damage to the die holder due to stress concentration, and extending the life of the die holder. It solves the problems mentioned in the above technical background.

[0005] To achieve the above objectives, the present invention provides the following technical solution: a die base for stamping irregular metal parts, the die base including a base, a lower support plate and a die base body disposed on the base, a buffer mechanism and a guide mechanism disposed between the base and the lower support plate, the base including a seat body, the lower support plate including a plate body, wherein the lower support plate is disposed between the base and the die base body, the die base body is fixed on the lower support plate, the seat body is attached to the lower end face of the plate body, a fixing shell is fixed at the bottom of the plate body, and a groove is formed in the fixing shell;

[0006] The buffer mechanism includes a bladder, which includes a horizontal part and two recessed parts respectively disposed at both ends of the horizontal part. The two recessed parts are symmetrical to the two ends of the horizontal part. The guide mechanism includes an upper guide cap and a guide rod. The upper guide cap is a hollow cavity structure with an opening at the bottom and is fixed to the plate. The guide rod is fixed to the base. A fixing plate is fixed to the top of the guide rod. Both the guide rod and the fixing plate are slidably disposed in the cavity of the upper guide cap.

[0007] Preferably, a receiving groove is provided on the upper end face of the seat, the bladder is received in the receiving groove, and the bladder is fixed to the inner wall of the receiving groove.

[0008] Preferably, both sides of the receiving groove are provided with ramps, which are inclined at an angle between 3° and 10°. When the horizontal part is compressed and deformed at the same time as the sinking part, the two sinking parts will extend to both sides of the receiving groove and be flattened. Under the action of the two ramps, the two sinking parts gradually fit into the plate and play a certain buffering role between the seat and the plate, dispersing the mechanical stress between the seat and the plate, thereby protecting the seat and the plate.

[0009] Preferably, gas-containing grooves are provided on both sides of the receiving groove, and the two gas-containing grooves are symmetrical to the two sides of the base. The width of the gas-containing groove on the side away from the receiving groove gradually decreases, and the space inside the gas-containing groove is used to contain the gas squeezed out from the receiving groove.

[0010] Preferably, the groove is located above the bladder body, and the height of the groove is between 0.5 mm and 1.5 mm, and the length of the groove is equal to the length of the bladder body.

[0011] Preferably, the height of the horizontal part is greater than the height of the sunken part, and the height of the horizontal part is between 4mm and 6mm, while the height of the sunken part is between 2mm and 3.5mm.

[0012] Preferably, the guide rod is inserted into the cavity of the upper guide cap from bottom to top, and the guide rod is in contact with the inner wall of the cavity of the upper guide cap, so that the guide rod can only slide vertically in the upper guide cap without shaking, ensuring that there is no shaking or disordered vibration between the seat and the plate, and only slight vertical movement when subjected to greater pressure, thereby ensuring the precision of the seat and the plate.

[0013] Preferably, a sealing ring is fixedly sleeved on the outside of the fixed plate, and the sealing ring fits against the inner wall of the cavity of the upper guide cap.

[0014] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0015] This utility model provides a die holder for stamping irregularly shaped metal parts. The die holder includes a base, a lower support plate and a die holder body disposed on the base. A buffer mechanism and a guide mechanism are provided between the base and the lower support plate. The overall structure is simple and reasonably designed. When the die holder body is subjected to pressure during operation, the pressure is released downward layer by layer, causing the plate to exert pressure on the bladder. At this time, the horizontal part of the bladder is deformed by pressure and the pressure is dispersed to the downward parts on both sides. The pressure diffuses into the receiving grooves on both sides of the bladder, and under the action of the slope on both sides, a corresponding interaction force is generated between the bladder and the plate. Therefore, the bladder plays a buffering role between the plate and the die holder, reducing the impact of pressure on the die holder and the plate, making the die holder more capable of withstanding pressure and suitable for widespread use.

[0016] The buffer mechanism of this utility model includes a bladder, which includes a horizontal part and two recessed parts respectively disposed at both ends of the horizontal part. The two recessed parts are symmetrical to the two ends of the horizontal part. Through the arrangement of the bladder and the guide mechanism on both sides of the bladder, the bladder can guide the seat and the plate, making the relative movement between the seat and the plate more controllable. Therefore, it will not produce shaking or disordered vibration, avoid affecting the precision of the mold base, effectively disperse mechanical stress, prevent the mold base from being damaged due to stress concentration, extend the life of the mold base, and is suitable for widespread use.

[0026] Please see Figure 1 The present invention provides an embodiment of a stamping die base for irregularly shaped metal parts, the stamping die base for irregularly shaped metal parts includes a base 1, a lower support plate 2 disposed on the base 1 and a die base body 3, wherein the lower support plate 2 is disposed between the base 1 and the die base body 3, and the die base body 3 is fixed on the lower support plate 2.

[0027] Please see Figure 2 A buffer mechanism 4 and a guide mechanism 5 are provided between the base 1 and the lower support plate 2. There are two sets of guide mechanisms 5, and the two sets of guide mechanisms 5 are symmetrical to the base 1.

[0028] Please see Figure 3The base 1 includes a seat body 11, with a receiving groove 12 provided on the upper end surface of the seat body 11. Both sides of the receiving groove 12 are provided with ramps 121, which are inclined at an angle between 3° and 10°. The lower support plate 2 includes a plate body 21, with the seat body 11 fitting against the lower end surface of the plate body 21. A fixing shell 22 is fixed to the bottom of the plate body 21, and a groove 221 is formed within the fixing shell 22. The height of the groove 221 is between 0.5mm and 1.5mm. The buffer mechanism 4 includes a bladder 41, which is housed within a receiving groove 12 and fixed to the inner wall of the receiving groove 12. A groove 221 is disposed above the bladder 41, and the length of the groove 221 is equal to the length of the bladder 41. The bladder 41 includes a horizontal portion 411 and recessed portions 412 respectively disposed at both ends of the horizontal portion 411. The height of the horizontal portion 411 is greater than the height of the recessed portions 412, and the height of the horizontal portion 411 is between 4 mm and 6 mm. The height of the recessed portion 412 is between 2mm and 3.5mm. The two recessed portions 412 are symmetrical about the two ends of the horizontal portion 411. During use, when the mold base body 3 is subjected to pressure and releases it layer by layer downwards, the horizontal portion 411 is compressed and deforms simultaneously with the recessed portions 412. The two recessed portions 412 extend towards both sides of the receiving groove 12 and are gradually flattened. Under the action of the two ramps 121, the two recessed portions 412 gradually move upwards and fit against the plate 21, so that the horizontal portion 411 and the recessed portions 412 at both ends play a certain buffering role between the base 11 and the plate 21, disperse the mechanical stress between the base 11 and the plate 21, prevent the mold base from being damaged due to stress concentration, extend the life of the mold base, and play a protective role for the base 11 and the plate 21. The bladder 41 reduces the impact of pressure on the base 11 and the plate 21, thus effectively reducing the pressure borne by the plate 21 and the base 11, making the mold base more capable of withstanding pressure.

[0029] Please see Figure 4 Gas-containing grooves 13 are provided on both sides of the receiving groove 12, and the two gas-containing grooves 13 are symmetrical to the two sides of the base 11. The width of the gas-containing groove 13 on the side away from the receiving groove 12 gradually decreases. The space inside the gas-containing groove 13 is used to contain the gas squeezed out from the receiving groove 12.

[0030] Please see Figure 5The guiding mechanism 5 includes an upper guide cap 51 and a guide rod 52. The upper guide cap 51 is a hollow cavity structure with an opening at the bottom, and it is fixed to the plate 21. The guide rod 52 is fixed to the base 11, and a fixing plate 53 is fixed to the top of the guide rod 52. Both the guide rod 52 and the fixing plate 53 are slidably disposed within the cavity of the upper guide cap 51. The guide rod 52 passes through the cavity of the upper guide cap 51 from bottom to top, and it fits against the inner wall of the cavity of the upper guide cap 51. This allows the guide rod 52 to slide vertically within the upper guide cap 51 without shaking, ensuring that there is no shaking or disordered vibration between the base 11 and the plate 21. Only slight vertical movement occurs when subjected to greater pressure, thus ensuring the precision of the base 11 and the plate 21, and protecting the precision of the mold base. A sealing ring 54 is fixedly sleeved on the outer side of the fixed plate 53. The sealing ring 54 fits against the inner wall of the cavity of the upper guide cap 51. In this embodiment, the sealing ring 54 is made of rubber and is used to buffer between the upper guide cap 51 and the fixed plate 53 to reduce wear. When the plate 21 applies downward pressure on the seat 11, the plate 21 will generate a small movement in the vertical direction and drive the two upper guide caps 51 to sink slightly. Therefore, the two upper guide caps 51 will move vertically on the two guide rods 52 to avoid shaking or disorderly vibration between the seat 11 and the plate 21. Therefore, the guide mechanism 5 can guide between the seat 11 and the plate 21, making the relative movement between the seat 11 and the plate 21 more controllable.

[0031] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention. No reference numerals in the claims should be construed as limiting the scope of the claims.
