[0002] Auto parts refer to parts or components with specific functions that make up a car (including the entire vehicle and its subsystems). During the actual processing and forming process, they will be stamped in conjunction with dies. Among them, continuous stamping dies, also known as progressive dies, are a type of die. They refer to dies that can complete multiple processes such as blanking, punching, bending, and stretching through multiple continuous stations in a single stamping process. Aluminum alloy is one of the commonly used materials for auto parts.

DETAILED DESCRIPTION

[0029] In order to make the above-mentioned objects, features and advantages of the present invention more obvious and easy to understand, the specific embodiments of the present invention are described in detail below with reference to the accompanying drawings.

[0030] In the following description, many specific details are set forth to facilitate a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Those skilled in the art may make similar generalizations without violating the connotation of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0031] Secondly, the term "one embodiment" or "embodiment" herein refers to a specific feature, structure, or characteristic that may be included in at least one implementation of the present invention. The phrase "in one embodiment" appearing in various places throughout this specification does not necessarily refer to the same embodiment, nor does it refer to a separate or selective embodiment that is mutually exclusive of other embodiments. Example 1

[0032] Reference Figure 1 and Figure 2 , which is the first embodiment of the present invention, provides a plastic mold for automobile parts processing, which includes a molding component 1, a guide component 2 and an anti-blocking component 3. Through the arrangement of the guide component 2 and the anti-blocking component 3, when there is no stamping operation, the guide component 2 can support the transmission coil and fill the transmission space of the coil to the next workstation; during the stamping operation, the guide component 2 automatically moves out to ensure the normal stamping operation, and at the same time cooperates with the anti-blocking component 3 to move and guide, so as to avoid the residual stamping waste affecting the normal stamping process. No additional traction and dredging are required, and it can form precise coordination with the stamping action without manual intervention, which not only reduces the labor intensity of manual operation, but also avoids the safety hazards that may be caused by manual intervention.

[0033] Specifically, the molding assembly 1 includes a lower mold 11 , and an upper mold 12 is provided on the top of the lower mold 11 .

[0034] The material of the lower mold 11 and the upper mold 12 are both plastic. In the processing of automotive parts, they can achieve significant lightweighting to reduce energy consumption and adapt to the molding of complex structures. They have the advantages of weather resistance and corrosion resistance, controllable cost and functional customization, which are in line with the mass production and performance requirements of the automotive industry. Through the setting of the lower mold 11 and the upper mold 12, the upper mold 12 can be fixed to the part on the slider of the stamping equipment. As the slider moves up and down, pressure is applied to the blank through the working part of the punch-upper mold 12 to complete the punching, bending, stretching deformation or separation process, and the working part of the die-lower mold 11 forms a matching gap with the punch of the upper mold, and they work together to separate the blank such as punching or deform it such as bending and stretching. The working principle of this part is all existing technology, which can be clearly understood by those skilled in the art and will not be elaborated here.

[0035] Specifically, the guide assembly 2 is arranged at the top of the lower mold 11, and includes a positioning column 21 slidably connected to the lower mold 11. The outer ring of the positioning column 21 is provided with a ring groove 21-2. The bottom of the outer ring of the positioning column 21 is rotatably connected to a rotating ring 22. The outer ring of the rotating ring 22 is fixed with a rotating frame 23. A displacement plate 24 is provided on the top of the rotating frame 23. A lubricating part 25 is installed on the rotating frame 23. A supporting block 26 is fixed to the top of the lower mold 11.

[0036] By setting the positioning column 21 and the annular groove 21-2, the transmission coil can be positioned by the annular groove 21-2, and during the stamping process, the upper mold 12 first contacts the positioning column 21 and presses the positioning column 21 downward, while making the coil move down stably close to the lower mold 11, ensuring the stamping processing accuracy.

[0037] By setting the lubricating member 25, multiple oil droplets can be formed to lubricate the side of the coil, effectively reducing the contact friction between the side of the coil and the positioning column 21 and the displacement plate 24, which is conducive to the smooth feeding of the end face of the coil.

[0038] Specifically, the anti-blocking component 3 is arranged in the lower mold 11, and includes a baffle 31 slidably connected to the lower mold 11, a bracket 32 ​​is fixed to the bottom of the baffle 31, a fixing frame 34 is fixed to one end of the bracket 32, a hollow shifting frame 35 is provided on the top of the fixing frame 34, and guide frames 33 are provided on both sides of the hollow shifting frame 35.

[0039] The hollow shifting frame 35 can move along with the bracket 32 ​​to shift the stamping waste, thus preventing the waste from tilting and getting stuck, thereby affecting the normal stamping process. Example 2

[0040] Reference Figures 2 to 10 , which is the second embodiment of the present invention, and this embodiment is based on the previous embodiment.

[0041] Specifically, a material trough 11-1 is opened in the lower mold 11, a receiving groove 11-2 is opened on the top side of the lower mold 11, a slide groove 11-3 is opened in the receiving groove 11-2, a positioning hole 11-4 is opened on the top of the lower mold 11, and a mold groove 11-5 is opened on the top of the lower mold 11. The bottom of the inner cavity of the mold groove 11-5 is connected to the top of the inner cavity of the material trough 11-1.

[0042] The actual specifications of the die groove 11-5 are larger than the specifications of the waste material, which can effectively reduce the probability of waste material getting stuck.

[0043] A spiral groove 21-1 is provided on the outer ring of the positioning column 21, and a convex ball 22-1 is fixed on the inner ring of the rotating ring 22 and is slidably connected to the spiral groove 21-1. A first spring 21-3 is fixed to the bottom end of the positioning column 21, and the bottom of the first spring 21-3 is fixed in the positioning hole 11-4. An inclined groove 26-1 is provided on the top of the supporting block 26.

[0044] The storage slot 11 - 2 is used to meet the rotation space requirement of the rotating frame 23 , and the bottom of the supporting block 26 is fixed in the storage slot 11 - 2 .

[0045] In actual application, a rectangular rod is fixed at the bottom of the inner cavity of the positioning hole 11-4, and a rectangular groove is opened at the center of the bottom of the positioning column 21. The rectangular rod is slidably connected in the rectangular groove. This design not only improves the stability of the up and down displacement of the positioning column 21, but also avoids the rotation of the positioning column 21.

[0046] The convex ball 22-1 extends into the spiral groove 21-1 and is slidably connected to the spiral groove 21-1. The central angle of the spiral groove 21-1 is 90 degrees, as shown in the accompanying drawings of the specification. Figure 5As shown, when the positioning post 21 is pressed downward by the upper mold 12 and moves, the convex ball 22 - 1 and the spiral groove 21 - 1 cooperate to make the rotating ring 22 rotate 90 degrees clockwise, thereby rotating the rotating frame 23 in conjunction.

[0047] A positioning frame 24-1 is fixed to the bottom of the displacement plate 24, and the positioning frame 24-1 is slidably connected to the rotating frame 23. A second spring 24-2 is provided on the outer ring of the positioning frame 24-1. The top of the second spring 24-2 is fixed to the bottom of the rotating frame 23, and the bottom of the second spring 24-2 is fixed to the positioning frame 24-1. The top of the displacement plate 24 is rotatably connected to the homogenizing roller 24-3.

[0048] The bottom of the transmission coil can be smeared with a rolling brush by the homogenizing roller 24-3, thereby helping to improve the uniformity of the oil distribution on the coil.

[0049] The inclined groove 26 - 1 can be provided so that when the positioning frame 24 - 1 rotates counterclockwise, the positioning frame 24 - 1 contacts the inclined groove 26 - 1 , thereby pressing the displacement plate 24 to move upward for a distance.

[0050] The second spring 24-2 is configured to be compressed and store energy when the positioning frame 24-1 moves upward. When there is no external force acting on the positioning frame 24-1, the positioning frame 24-1 and the displacement plate 24 are maintained in a low position to avoid affecting the normal stamping between the lower mold 11 and the upper mold 12.

[0051] The lubricating part 25 includes a hollow plate 25-1 embedded in the displacement plate 24, a suspended condensation head 25-11 is embedded on the top of the hollow plate 25-1, an airbag 25-2 is provided at the bottom of the rotating frame 23, a sealing soft film 25-21 is fixed in the airbag 25-2, and an oil replenishing valve 25-22 is fixed on the top of the airbag 25-2.

[0052] An oil delivery pipe 25-3 is fixed to the top of the airbag 25-2, and the other end of the oil delivery pipe 25-3 is fixed to the hollow plate 25-1. An air intake pipe 25-4 is fixed to the bottom of the airbag 25-2, and an air delivery pipe 25-5 is fixed to the bottom end of the air intake pipe 25-4.

[0053] One-way valves are fixed on the oil delivery pipe 25-3 and the air intake pipe 25-4, which can allow the lubricating oil in the airbag 25-2 to be transported unidirectionally through the oil delivery pipe 25-3 and placed into the hollow plate 25-1; while the outside air is unidirectionally replenished into the airbag 25-2 through the air intake pipe 25-4.

[0054] When the oil replenishing valve 25-22 is in the open state, the staff can actively replenish the lubricating oil into the airbag 25-2 and place it above the sealing soft film 25-21.

[0055] The suspended condensation head 25-11 is a fluororubber annular sleeve with a wide temperature range of up to 300°C, strong chemical corrosion resistance, and stable compatibility with various lubricants. It can maintain its structure and sealing performance for a long time in harsh environments, ensuring the suspended condensation state of the lubricant.

[0056] When the airbag 25-2 rotates ninety degrees along with the rotating frame 23, it will contact with the baffle 31 and be squeezed, so that the oil above the sealing soft film 25-21 is transmitted to the hollow plate 25-1 through the oil pipe 25-3, and the oil is distributed into a suspended state by the suspension head 25-11. As the coil is fed, its end face comes into contact with the oil droplets and is lubricated, and is evenly coated in cooperation with the equalizing roller 24-3.

[0057] As the lubricating oil in the upper part of the airbag 25-2 is consumed, after the airbag 25-2 is deformed and reset, the gas is replenished into the airbag 25-2 through the air intake pipe 25-4, and the sealing soft film 25-21 moves up a distance.

[0058] A third spring 31 - 1 is fixed on both sides of the bottom of the baffle 31 . The bottom end of the third spring 31 - 1 is fixed in the slide groove 11 - 3 . A displacement groove 34 - 1 is opened at the bottom of the fixing frame 34 . A corrugated sleeve 34 - 2 is fixed on the fixing frame 34 . The other end of the corrugated sleeve 34 - 2 is fixed on the hollow shifting frame 35 .

[0059] A displacement block 35 - 2 is fixed to the bottom of the hollow shifting frame 35 . The displacement block 35 - 2 is hollow, and the top of its inner cavity is connected to the bottom of the inner cavity of the hollow shifting frame 35 . The surface of the displacement block 35 - 2 is slidably connected to the displacement groove 34 - 1 .

[0060] The hollow shifting frame 35 is provided with air inlet holes 35 - 1 . The number of the air inlet holes 35 - 1 is several and evenly distributed on the hollow shifting frame 35 .

[0061] Guide blocks 35 - 3 are fixed on both sides of the hollow shifting frame 35 . A guide groove 33 - 1 is defined in the guide frame 33 , and the surfaces of the guide blocks 35 - 3 are slidably connected in the guide groove 33 - 1 .

[0062] The setting of the guide block 35-3 and the guide groove 33-1 can play a role in positioning and guiding. When the hollow shifting frame 35 moves downward, it will be guided by the shape of the guide groove 33-1 and produce displacement in other directions, which is used to complete the shifting of the waste in the mold cavity 11-5.

[0063] The arrangement of the corrugated sleeve 34 - 2 has a telescopic characteristic, which can cover and shield the top of the fixing frame 34 to prevent waste from being stuck on the fixing frame 34 .

[0064] During use, after the coil is flattened, it is transferred between the lower mold 11 and the upper mold 12 through the external continuous feeding equipment. When the upper mold 12 is in a high position, that is, when not punching, the coil is fed a distance. At this time, under the elastic support of the first spring 21-3, the positioning column 21 is in a high position, the rotating frame 23 is in a horizontal state, and under the support of the supporting block 26, the displacement plate 24 automatically moves up a distance. Under the elastic support of the third spring 31-1, the baffle 31 is in a high position, as shown in the accompanying drawings of the specification. Figure 5 As shown, the airbag 25-2 contacts the baffle 31 and is compressed, so that the lubricating oil enters the hollow plate 25-1 through the oil pipe 25-3 and finally condenses and protrudes on the condensation head 25-11.

[0065] As the coil is fed, one end of the coil first passes through the annular groove 21-2 to be positioned, and then placed on the displacement plate 24 to prevent it from falling and bending due to its own weight. As the coil is further transported, its end face comes into contact with the oil droplets, and with the assistance of the homogenizing roller 24-3, the lubricating oil is homogenized, which is conducive to the alignment and calibration with the subsequent positioning column 21 and the annular groove 21-2.

[0066] After the coil is fed, the upper die 12 is driven to move linearly downward to cooperate with the lower die 11 to complete the stamping process of the coil, and the processing waste falls into the die groove 11-5. The positioning column 21 and the baffle 31 are pressed downward synchronously.

[0067] When the positioning column 21 moves downward, the spiral groove 21-1 and the convex ball 22-1 cooperate to make the rotating frame 23 and the displacement plate 24 rotate clockwise to reset, and the airbag 25-2 is no longer in contact with the baffle 31. Under the elastic reset action, the outside air is unidirectionally replenished into the airbag 25-2 through the air inlet hole 35-1, the hollow shifting frame 35, the displacement block 35-2, the air supply pipe 25-5 and the air inlet pipe 25-4, and the flow of gas will assist in attracting thinner and lighter processing waste, thereby playing a role in assisting in preventing retention.

[0068] When the baffle 31 moves downward, the bracket 32 ​​drives the fixing frame 34 to move downward together, and with the cooperation of the guide block 35-3 and the guide groove 33-1, the hollow shifting frame 35 moves forward and backward while moving downward, which not only makes the hollow shifting frame 35 separate from the mold groove 11-5, avoiding damage to the hollow shifting frame 35 and the upper parts of the upper mold 12, but also the displacement of the hollow shifting frame 35 is used to shift the waste in the mold groove 11-5, thereby achieving the purpose of anti-blocking protection.

[0069] Similarly, with the completion of a single stamping, the upper mold 12 moves up, and under the elastic support of the first spring 21-3 and the third spring 31-1, the positioning column 21 and the baffle 31 automatically move up and reset, and then repeat the above-mentioned support anti-fall and oil extrusion lubrication operations. At the same time, the hollow shifter 35 is reset into the mold groove 11-5, which plays a secondary shifting anti-blocking role. In this cycle, when the lower mold 11 and the upper mold 12 cooperate in stamping, the anti-blocking and dredging operation is completed. After the upper mold 12 is reset, the support anti-fall and lubrication protection operations are completed when the coil is fed. No manual intervention is required as a whole. Example 3

[0070] Reference Figures 3 to 10 , which is the third embodiment of the present invention, is based on the first two embodiments.

[0071] Specifically, the oil delivery pipe 25 - 3 is designed as a telescopic hose, that is, when the displacement plate 24 moves upward, the air bag 25 - 2 and the hollow plate 25 - 1 can still be well connected.

[0072] The air delivery pipe 25-5 is designed as a telescopic hose, that is, after the rotating frame 23 and the air bag 25-2 rotate 90 degrees to reset, it can still ensure that the displacement block 35-2 and the air intake pipe 25-4 are well connected.

[0073] In actual application, the specifications of the guide frame 33 and the hollow shifting frame 35 can be flexibly changed according to the position and specifications of the mold cavity 11-5, so as to ultimately achieve a matching effect.

[0074] In actual application, a filter is embedded in the air inlet 35-1 to intercept dust and impurities in the external air to prevent the inhalation of impurities from affecting the normal circulation of the gas pipeline.

[0075] It should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention and are not intended to limit the present invention. Although the present invention has been described in detail with reference to the preferred embodiments, those skilled in the art should understand that the technical solutions of the present invention may be modified or replaced by equivalents without departing from the spirit and scope of the technical solutions of the present invention, which should all be included in the scope of the claims of the present invention.
