DETAILED DESCRIPTION

[0032] In order to make the above-mentioned objectives, features and advantages of the present application more obvious and easy to understand, the specific embodiments of the present application will be described in detail below with reference to the accompanying drawings.

[0033] In the following description, a lot of specific details are set forth in order to provide a thorough understanding of the present application, but the present application can also be implemented in other ways different from those described herein, and those skilled in the art can make similar generalizations without departing from the concept of the present application, so the present application is not limited to the specific embodiments disclosed below.

[0034] Secondly, the "one embodiment" or "embodiment" referred to herein means that the specific features, structures or characteristics can be included in at least one implementation of the present application. "In one embodiment" appearing in different places in the specification does not mean the same embodiment, nor is it an embodiment that is separate or alternative to other embodiments. Embodiment 1

[0035] Reference Figure 1 and Figure 2 For the first embodiment of the present application, the plastic mold for automobile accessory processing comprises a forming assembly 1, a guide assembly 2 and a anti-blocking assembly 3. Through the setting of the guide assembly 2 and the anti-blocking assembly 3, the transmission coil material can be supported by the guide assembly 2 when the stamping operation is not performed, and the transmission space of the coil material to the next station is filled. When the stamping operation is performed, the guide assembly 2 is automatically moved out to ensure normal stamping operation, and at the same time, the anti-blocking assembly 3 is used for stirring and dredging to avoid the influence of the residual stamping waste on the normal stamping processing. Without additional traction and dredging, the precise cooperation with the stamping action can be formed 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.

[0036] Specifically, the forming assembly 1 comprises a lower die 11, and the top of the lower die 11 is provided with an upper die 12.

[0037] The materials of the lower die 11 and the upper die 12 are both plastic. In the processing of automobile accessories, the energy consumption can be reduced by significantly reducing the weight, the complex structure forming can be adapted, the weather resistance and corrosion resistance can be achieved, the cost can be controlled, the function customization advantage can be achieved, the production and performance requirements of the automobile industry can be met, and through the setting of the lower die 11 and the upper die 12, the upper die 12 can be fixed on the part of the slide block of the stamping equipment and move up and down with the slide block. The work parts of the punch and the upper die 12 apply pressure to the blank to complete the blanking, bending, stretching deformation or separation process. The work parts of the concave die and the lower die 11 form a cooperation gap with the punch of the upper die, and together they make the blank separate, such as blanking, or deform, such as bending and stretching. The working principle of this part is the existing technology, and those skilled in the art can clearly understand it, which will not be repeated here.

[0038] Specifically, the guide assembly 2 is arranged on the top of the lower die 11 and comprises a positioning column 21 which is slidingly connected to the lower die 11. An annular groove 21-2 is formed in the outer circle of the positioning column 21. A rotating ring 22 is rotatably connected to the bottom of the outer circle of the positioning column 21. A rotating frame 23 is fixed to the outer circle of the rotating ring 22. A displacement plate 24 is arranged 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 die 11.

[0039] Through the setting of the positioning column 21 and the annular groove 21-2, the transmission coil material can be positioned by the annular groove 21-2. During the stamping process, the upper die 12 first contacts and presses the positioning column 21 to move downward, and at the same time, the coil material is stably moved downward to be close to the lower die 11, so as to ensure the stamping processing precision.

[0040] Through the setting of the lubricating part 25, multi-point oil drop supply for the coil edge side lubrication can be formed, the friction force between the coil edge side and the positioning column 21 and the displacement plate 24 is effectively reduced, and the coil end face is smoothly fed.

[0041] Specifically, the anti-blocking assembly 3 is arranged in the lower die 11 and includes a baffle 31 slidably connected to the lower die 11, a support 32 fixed to the bottom of the baffle 31, a fixed frame 34 fixed to one end of the support 32, and a hollow stirring frame 35 arranged at the top of the fixed frame 34 and provided with guide frames 33 on both sides.

[0042] Through the setting of the hollow stirring frame 35, the hollow stirring frame 35 can act together with the support 32 to stir the stamping waste, so that the waste is prevented from being tilted and stuck to affect normal stamping processing. Embodiment 2

[0043] Reference Figures 2-10 This is a second embodiment of the present application, which is based on the previous embodiment.

[0044] Specifically, a material groove 11-1 is arranged in the lower die 11, a receiving groove 11-2 is arranged at the top of the lower die 11, a sliding groove 11-3 is arranged in the receiving groove 11-2, a positioning hole 11-4 is arranged at the top of the lower die 11, a die groove 11-5 is arranged at the top of the lower die 11, and the inner cavity bottom of the die groove 11-5 is in communication with the inner cavity top of the material groove 11-1.

[0045] The actual specification of the die groove 11-5 is greater than that of the waste, which can effectively reduce the probability of waste jamming.

[0046] A spiral groove 21-1 is arranged at the outer circle of the positioning column 21, a convex ball 22-1 is fixed to the inner circle of the rotating ring 22 and 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 fixed in the positioning hole 11-4, and an inclined groove 26-1 is arranged at the top of the supporting block 26.

[0047] The receiving groove 11-2 is arranged to meet the rotating space requirement of the rotating frame 23, and the bottom of the supporting block 26 is fixed in the receiving groove 11-2.

[0048] In actual application, a rectangular rod is fixed in the inner cavity bottom of the positioning hole 11-4, a rectangular groove is arranged at the bottom center of the positioning column 21, and the rectangular rod is slidably connected to the rectangular groove. This design not only improves the stability of the up-down displacement of the positioning column 21, but also avoids the rotating action of the positioning column 21.

[0049] 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 ninety degrees, as shown in the accompanying drawings. Figure 5As shown, when the positioning column 21 is pressed by the upper die 12, the convex ball 22-1 and the spiral groove 21-1 cooperate, so that the rotating ring 22 rotates clockwise by ninety degrees, and the rotating frame 23 rotates by linkage.

[0050] The bottom of the displacement plate 24 is fixed with a positioning frame 24-1 which is slidingly connected to the rotating frame 23. The outer ring of the positioning frame 24-1 is sleeved with a second spring 24-2, the top end of the second spring 24-2 is fixed to the bottom of the rotating frame 23, and the bottom end of the second spring 24-2 is fixed to the positioning frame 24-1. The top of the displacement plate 24 is rotationally connected with a leveling roller 24-3.

[0051] The leveling roller 24-3 can roll and brush the bottom of the transmission coiled material, which can assist in improving the uniformity of the oil distribution on the coiled material.

[0052] The inclined groove 26-1 is arranged to contact the positioning frame 24-1 during counterclockwise rotation of the positioning frame 24-1, and then press the displacement plate 24 to move a distance.

[0053] The second spring 24-2 is arranged to be compressed and stored when the positioning frame 24-1 moves up, and when the positioning frame 24-1 is not subjected to external force, the positioning frame 24-1 and the displacement plate 24 are maintained in a low position state, which avoids affecting the normal stamping between the lower die 11 and the upper die 12.

[0054] The lubricating part 25 includes a hollow plate 25-1 embedded in the displacement plate 24, and a suspension condensation head 25-11 is embedded in the top of the hollow plate 25-1. The bottom of the rotating frame 23 is provided with an air bag 25-2, the air bag 25-2 is fixed with a sealed soft film 25-21, and the top of the air bag 25-2 is fixed with an oil supplement valve 25-22.

[0055] The top of the air bag 25-2 is fixed with an oil delivery pipe 25-3, the other end of the oil delivery pipe 25-3 is fixed to the hollow plate 25-1, the bottom of the air bag 25-2 is fixed with an air inlet pipe 25-4, and the bottom end of the air inlet pipe 25-4 is fixed with an air delivery pipe 25-5.

[0056] The oil delivery pipe 25-3 and the air inlet pipe 25-4 are both fixed with a one-way valve, so that the lubricating oil in the air bag 25-2 is one-way transmitted into the hollow plate 25-1 through the oil delivery pipe 25-3, and the external air is one-way supplemented into the air bag 25-2 through the air inlet pipe 25-4.

[0057] The oil supplement valve 25-22 can be opened to actively supplement the lubricating oil into the air bag 25-2 above the sealed soft film 25-21 by the staff.

[0058] Suspension head 25-11 is a fluororubber ring sleeve, which has a wide temperature resistance range up to 300℃, strong chemical corrosion resistance, and is compatible with various lubricating oils, and can maintain the structure and sealing performance for a long time in harsh environments, ensuring the suspension state of the lubricating oil.

[0059] When the air bag 25-2 rotates ninety degrees with the rotating frame 23, it will be in contact with the baffle 31 and be extruded, so that the oil above the sealing soft film 25-21 is transmitted to the hollow plate 25-1 through the oil delivery pipe 25-3, and the oil is distributed by the suspension head 25-11 to form a suspension state, and the end surface is in contact with the oil droplets to be lubricated, and is evenly coated by the homogenizing roller 24-3.

[0060] As the upper lubricating oil in the air bag 25-2 is consumed, after the air bag 25-2 is deformed and reset, the gas will be supplemented into the air bag 25-2 through the air inlet pipe 25-4, and the sealing soft film 25-21 will move up by a distance.

[0061] The bottom of the baffle 31 is fixed with a third spring 31-1 on both sides, and the bottom end of the third spring 31-1 is fixed in the sliding groove 11-3. The bottom of the fixed frame 34 is provided with a displacement slot 34-1, and the fixed frame 34 is fixed with a corrugated sleeve 34-2, and the other end of the corrugated sleeve 34-2 is fixed on the hollow shifting frame 35.

[0062] The bottom of the hollow shifting frame 35 is fixed with a displacement block 35-2, and the displacement block 35-2 is hollow, and the inner cavity top is communicated with the inner cavity bottom of the hollow shifting frame 35, and the surface of the displacement block 35-2 is slidingly connected to the displacement slot 34-1.

[0063] The hollow shifting frame 35 is provided with a plurality of air inlet holes 35-1, which are evenly distributed on the hollow shifting frame 35.

[0064] The two sides of the hollow shifting frame 35 are fixed with guide blocks 35-3, and the guide frame 33 is provided with guide slots 33-1, and the surfaces of the guide blocks 35-3 are slidingly connected in the guide slots 33-1.

[0065] Through the setting of the guide block 35-3 and the guide slot 33-1, the positioning and guiding effect can be achieved, and when the hollow shifting frame 35 moves down, it will be guided by the shape of the guide slot 33-1 to produce displacement in other directions, so as to complete the shifting of the waste in the mold groove 11-5.

[0066] Through the setting of the corrugated sleeve 34-2, the fixed frame 34 top can be covered and shielded, so as to avoid the waste from being stuck on the fixed frame 34.

[0067] In use, after the coil material is flattened, it is continuously fed to the lower die 11 and the upper die 12 through an external continuous feeding device. When the upper die 12 is in the high position, i.e. not in the punching state, the coil material is fed a distance. At this time, under the elastic support of the first spring 21-3, the positioning column 21 is in the high position, the rotating frame 23 is in the horizontal state, 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 the high position, as shown in the drawings Figure 5 The air bag 25-2 is in contact with the baffle 31 and is compressed, so that the lubricating oil enters the hollow plate 25-1 from the oil pipe 25-3, and finally suspends and protrudes on the suspension head 25-11.

[0068] With the feeding of the coil material, one end of the coil material first passes through the ring groove 21-2 and is positioned, and then is placed on the displacement plate 24 to avoid falling and bending due to its own weight. With the further transmission of the coil material, its end surface is in contact with the oil droplets, and under the assistance of the leveling roller 24-3, the lubricating oil is leveled, which is beneficial to the alignment and calibration of the subsequent positioning column 21 and ring groove 21-2.

[0069] After the coil material is fed, the upper die 12 is driven to move linearly downward to cooperate with the lower die 11 to complete the punching processing of the coil material, and the processing waste falls into the die groove 11-5. The positioning column 21 and the baffle 31 are synchronously pressed down.

[0070] When the positioning column 21 moves down, the rotating frame 23 and the displacement plate 24 are rotated clockwise to reset under the cooperation of the spiral groove 21-1 and the convex ball 22-1. The air bag 25-2 is no longer in contact with the baffle 31. Under the elastic reset action, external air is supplemented into the air bag 25-2 through the air inlet hole 35-1, the hollow shifting frame 35, the displacement block 35-2, the gas conveying pipe 25-5 and the air inlet pipe 25-4. The flow of gas will assist the movement of the relatively thin and light processing waste, achieving the effect of auxiliary anti-retention.

[0071] When the baffle 31 moves down, the fixed frame 34 moves down together with the bracket 32, and under the cooperation of the guide block 35-3 and the guide groove 33-1, the hollow shifting frame 35 moves down while producing forward and backward displacement. Not only does this make the hollow shifting frame 35 separate from the die groove 11-5, avoiding contact between the hollow shifting frame 35 and the upper part of the upper die 12, but also the displacement of the hollow shifting frame 35 is used to shift the waste in the die groove 11-5, achieving the purpose of anti-blocking protection.

[0072] Similarly, with the completion of single stamping, the upper die 12 moves up, and the positioning column 21 and the baffle 31 are automatically moved up and reset under the elastic support of the first spring 21-3 and the third spring 31-1, and then the above-mentioned support and oil extrusion lubrication operations are repeated, and at the same time, the hollow pushing frame 35 is reset into the mold groove 11-5, playing the role of secondary pushing and anti-blocking, and thus the cycle is repeated. When the lower die 11 and the upper die 12 cooperate to stamp, the anti-blocking and dredging operations are completed, and after the upper die 12 is reset, the support and lubrication protection operations are completed when the coiled material is fed, and the whole does not need manual intervention. Embodiment 3

[0073] With reference to Figures 3-10 For the third embodiment of the present application, the embodiment is based on the first two embodiments.

[0074] Specifically, the oil delivery pipe 25-3 is designed as a telescopic hose, that is, during the upward movement of the displacement plate 24, the air bag 25-2 and the hollow plate 25-1 can still be in good communication.

[0075] The gas delivery pipe 25-5 is designed as a telescopic hose, that is, after the rotary frame 23 and the air bag 25-2 are rotated by ninety degrees and reset, the displacement block 35-2 and the gas inlet pipe 25-4 can still be in good communication.

[0076] In actual application, according to the position and specification of the mold groove 11-5, the guide frame 33 and the hollow pushing frame 35 can be flexibly changed in specification, and finally the matching effect can be achieved.

[0077] In actual application, a filter screen is embedded in the gas inlet hole 35-1 for intercepting dust and impurities in the external air, so as to avoid the influence of impurities suction on the normal flow of the gas pipeline.

[0078] It should be noted that the above embodiments are only used to illustrate the technical solutions of the present application and are not limited. Although the present application 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 application can be modified or replaced by equivalents without departing from the spirit and scope of the technical solutions of the present application, and they should be covered in the scope of the claims of the present application.
