Description

Technical Field

[0001] The present application relates to the field of injection molded parts processing equipment, and in particular to a shearing device for cleaning residual material on the surface of injection molded products. Background Art

[0002] Injection molding, also known as injection molding, is a molding method that combines injection and molding. Its advantages include high production speed, high efficiency, automated operation, a wide variety of designs and colors, shapes ranging from simple to complex, and sizes ranging from large to small. Furthermore, it produces precise product dimensions, is easily updated, and can produce complex shapes. Injection molding is suitable for mass production and the molding of complex products.

[0003] In the prior art, an injection mold is usually provided with at least one injection port, through which molten material is injected into the mold. When the product cools down, it is naturally formed. However, there is often some residual material left at the injection port. Usually, the staff will use tools to cut off this residual material to complete the processing of the product. When processing some products, due to the narrow space inside the injection mold, the molten material cannot be filled quickly. In this case, multiple feed ports are generally opened on the injection mold to ensure that the molten material can be filled quickly and efficiently. This will result in a large amount of residual material on the surface of the product, which needs to be removed one by one by the staff, greatly reducing the efficiency of product processing.

[0004] To this end, the inventor provides a shearing device for cleaning excess material on the surface of an injection molded product. Summary of the Invention

[0005] In order to improve the efficiency of cleaning the residual material on the surface of the product, the present application provides a shearing device for cleaning the residual material on the surface of the injection molded product.

[0006] The present application provides a shearing device for cleaning residual material on the surface of injection molded products, which adopts the following technical solution:

[0007] A shearing device for cleaning residual material on the surface of injection molded products comprises a frame, a lifting plate for fixing the product is arranged on the frame, a first driving member for driving the lifting plate is arranged on the frame, and a plurality of shearing seats are also arranged on the frame, the shearing seats are arranged at the bottom of the lifting plate, two shearing blocks are rotatably connected to the shearing seats, the shearing blocks are provided with shearing knives, the two shearing blocks drive the two shearing knives to shear residual material, and a second driving component for driving the shearing blocks is provided on the frame.

[0008] By adopting the above technical solution, during operation, the product is fixed to the bottom of the lifting plate and moves downward under the action of the first drive member. The shear seat is fixed according to the position of the residual material. When the product is lowered, the residual material falls exactly between the two shear blocks. Under the action of the second drive assembly, the two shear blades cooperate to achieve the effect of shearing the residual material, thereby realizing the shearing of multiple residual materials. Cast products are usually produced in batches. Using shear blades in a fixed position can make the shearing effect of each product close to consistent. Compared with the different shearing lengths during manual shearing, the shearing effect of the product can be ensured. Shearing multiple residual materials at the same time can improve the efficiency of residual material shearing.

[0009] Preferably, the second driving assembly includes a support plate that is lifted and lowered in the frame, the frame is provided with a second driving member for driving the support plate, the shear seat is lifted and lowered with a lifting seat, the lifting seat is provided with a driving rod, the side wall of the shear block is provided with a driving groove, the driving rod cooperates with the driving groove to drive the rotation of the shear block, and the bottoms of multiple lifting seats are fixed on the support plate.

[0010] By adopting the above technical solution, the second driving member is used in conjunction with the support plate, so that multiple lifting seats can be driven to rise and fall at the same time, reducing the number of second driving members used, which can better adapt to the shearing of smaller products, and improve the convenience of using the second driving component. In addition, in conjunction with the driving rod and driving slot on the lifting seat, the shear block can be better driven to rotate, thereby improving the convenience of using the shear block.

[0011] Preferably, a return spring is provided between the lifting seat and the shearing seat, and the return spring is used to drive the lifting seat to descend.

[0012] By adopting the above technical solution, after the shearing knife completes shearing of the material, the return spring drives the lifting seat to descend, thereby opening the two shearing knives and allowing the remaining material after shearing to fall, and the subsequent product shearing can be automatically carried out.

[0013] Preferably, a limiting plate is provided on the shear seat, a limiting groove is provided on the side wall of the lifting seat in the vertical direction for slidingly cooperating with the limiting plate, and an abutting plane is formed at the bottom of the shear knife, and the abutting plane abuts against the upper side of the limiting plate.

[0014] By adopting the above technical solution and using the limiting groove in combination with the limiting plate, the lifting seat can slide more smoothly, thereby improving the stability of the lifting seat. It can also limit the rotation angle of the shearing block so that the cutting angle of the shearing knife in the residual material is the same each time, so that it can be adjusted according to the size of different residual materials, thereby improving the shearing effect of the residual material.

[0015] Preferably, the two shearing knives are provided with a mounting groove on the side close to each other, and the shearing knives are clamped in the mounting groove. The two shearing knives are provided with a countersunk groove on the side close to the arc, and a fixing bolt connected to the shear block thread is inserted into the countersunk groove.

[0016] By adopting the above technical solution, the shear knife can be installed and disassembled more conveniently, thereby improving the convenience of using the shear knife.

[0017] Preferably, when the abutting plane abuts against the upper side of the limiting plate, the sides of the two shearing blades that are close to each other are arranged in parallel.

[0018] By adopting the above technical solution, when the initial state of the shearing knives is set in parallel, the two shearing knives approach each other to cut the residual material, and will move away from the product, reducing damage to the product itself, and this moving distance is small, and it is not easy to affect the appearance of the product. When the residual material is cut, if the cutting position is not fine enough, the position after cutting can be adjusted and subsequent processing can be performed.

[0019] Preferably, a collection box is plugged into one side of the frame, and the collection box is arranged at the bottom of the shearing seat. The collection box is used to collect the remaining materials after shearing.

[0020] By adopting the above technical solution, the shearing residue can be quickly collected, the overall neatness of the shearing equipment is improved, and the convenience of using the shearing equipment is improved.

[0021] Preferably, the second drive includes a rotating shaft arranged at the end of the shear block away from the shear knife, two driving seats are provided on the shear seat, and a driving inclined groove is provided on the side wall of the driving seat. The rotating shaft slides in the driving inclined groove to drive the switch of the two shear blocks, and a lifting groove is provided on the shear seat. A slider is slidably connected in the lifting groove, and the two shear blocks are rotatably connected to the slider. A driving spring for driving the slider to move upward is provided at the bottom of the lifting groove.

[0022] By adopting the above technical solution, after the product abuts against the shear block, the residual material can be inserted between the two shear blades. When the first driving member is controlled to descend, the rotating shaft slides in the driving groove, thereby driving the two shear blades to approach each other, thereby achieving the effect of shearing the residual material. After the shearing is completed, the two shears can be moved away from each other under the action of the driving spring, thereby facilitating the shearing of subsequent products and improving the convenience of using the device. With such a design, a first driving member can be used to realize the two-part work of feeding and shearing the product, so that the work can be carried out continuously, improving the smoothness of shearing products, and thus greatly improving the efficiency of shearing multiple residual materials at the same time.

[0023] Preferably, a support block is provided at the upper end of the shear block, and the support block is used to support the product.

[0024] By adopting the above technical solution, the direct impact of the product on the shear block and the shear knife is reduced to avoid damage to the product, thereby ensuring the shearing effect of the product.

[0025] Preferably, a stretching bar is provided between the two shearing blocks, the stretching bar is elastic, and the stretching bar is used to eject the remaining material after shearing.

[0026] By adopting the above technical solution, after the shearing is completed, the two shear blocks move away from each other, thereby tightening the stretching bar. After the stretching bar is tightened, it will produce a certain fluctuation, so that the residual material between the two shear blocks can be separated, reducing the residual material staying between the two shear blocks and affecting the shearing effect of subsequent products, thereby improving the convenience of using the shearing device.

[0027] In summary, this application includes at least one of the following beneficial technical effects:

[0028] 1. Two shears work together to achieve the effect of shearing the residual material, thereby realizing the shearing of multiple residual materials. Casting products are usually produced in batches. Using a fixed-position shear can make the shearing effect of each product close to the same. Compared with the different shearing lengths during manual shearing, it can ensure the shearing effect of the product; shearing multiple residual materials at the same time can improve the efficiency of residual material shearing.

[0029] 2. The second drive member is used in conjunction with the support plate to simultaneously drive multiple lifting seats to move up and down, reducing the number of second drive members used, better adapting to the shearing of smaller products, and improving the convenience of using the second drive assembly. In addition, the drive rod and drive slot on the lifting seat can better drive the shear block to rotate, improving the convenience of using the shear block;

[0030] 3. Using a first driving member can realize the two parts of feeding and shearing of the product, so that the work can be carried out continuously, improving the smoothness of shearing products, thereby greatly improving the efficiency of shearing multiple surplus materials at the same time.

DETAILED DESCRIPTION

[0037] The following is combined with Figure 1-5 This application is described in further detail.

[0038] The embodiment of the present application discloses a shearing device for cleaning residual material on the surface of an injection-molded product.

[0039] Example 1:

[0040] Reference Figure 1 and Figure 2 A shearing device for cleaning residual material on the surface of injection-molded products includes a frame 1. The frame 1 is a rectangular frame. The three sides of the frame 1 are closed by rectangular plates, and a working chamber is formed in the frame 1. A lifting plate 6 is installed in the frame 1 for lifting. The bottom of the lifting plate 6 is bolted to a mounting plate 11 for fixing the product. A plurality of clamping blocks for clamping the product protrude from the mounting plate 11. A first driving member 5 for driving the lifting plate 6 is fixed on the top of the frame 1. The first driving member 5 is a first driving cylinder. Four guide rods 2 are also fixed in the vertical direction in the frame 1. The four guide rods 2 are all arranged to pass through the lifting plate 6, and the four guide rods 2 are respectively located at the four corners of the lifting plate 6.

[0041] Reference Figure 1 and Figure 3A partition is fixed horizontally in the frame 1, and four support columns 3 are fixed on the partition. The support columns 3 are used to support the lifting plate 6, thereby limiting the height of the mounting plate 11. A plurality of shearing seats 8 are bolted to the partition. The shearing seats 8 are door-shaped. The shearing seats 8 are fixed to the bottom of the lifting plate 6 and are arranged one-to-one corresponding to the position of the residual material. Two ear plates are provided on the shearing seat 8. Two shearing blocks 7 are rotatably connected to the ear plates. The shearing blocks 7 are provided with shear knives 14. The two shearing blocks 7 drive the two shear knives 14 to shear the residual material. The two sides of the shearing blocks 7 close to each other are both carded and have mounting grooves 13. The shear knives 14 are fixed in the mounting grooves 13. The two shearing knives 14 close to each other are both provided with countersunk grooves 20. The countersunk grooves 20 are inserted with fixing bolts 21 that are threadedly connected to the shearing blocks 7. A second drive component for driving the shearing blocks 7 is provided on the frame 1.

[0042] Reference Figure 1 and Figure 2 The second drive assembly includes a support plate 12 that is connected to the frame 1 for lifting and lowering. The support plate 12 is a rectangular plate and is arranged at the bottom of the partition plate. A second drive member 10 for driving the support plate 12 to rise and fall is fixed in the frame 1. A lifting seat 9 is connected to the shear seat 8 for lifting and lowering. The base of the lifting seat 9 is threadedly connected to an adjustment column 19, and the bottom of the adjustment column 19 is bolted to the lifting plate 6. The lifting seat 9 is U-shaped and plugs into the door-shaped structure of the shear seat 8. A return spring 22 is installed between the lifting seat 9 and the shear seat 8. The return spring 22 is used to drive the lifting seat 9 to descend, thereby resetting the shear blade 14. Two drive rods 15 are rotatably connected to the shear seat 8. The two drive rods 15 are respectively arranged at both ends of the U-shaped structure. A drive slot 16 is opened on the side wall of the shear block 7. The drive slot 16 cooperates with the drive rod 15 to drive the shear block 7 to rotate. This design reduces the size of the second drive assembly, allowing multiple shear blades 14 to be more easily accommodated within the frame 1. This allows the shear blades 14 to be more adaptable to smaller structures, improving the ease of use of the shearing device. A collection box 4 is plugged into one side of the chassis. The collection box 4 is a rectangular box with a rectangular cavity defined on its upper side. The collection box 4 is located at the base of the shear seat 8 and is used to collect the remaining material after shearing.

[0043] Reference Figure 3 and Figure 4A limit plate 17 is fixed to the shear seat 8. The limit plate 17 is U-shaped, and the top of the limit plate 17 is set horizontally. The side wall of the lifting seat 9 is provided with a limit groove 18 in the vertical direction, which slides with the limit plate 17. The bottom of the shear blade 14 is formed with an abutment plane. When the shear blade 14 is reset, the abutment plane abuts the upper side of the limit plate 17. At this time, the sides of the two shear blades 14 that are close to each other are set parallel. When the shear blades 14 are initially set in parallel, the two shear blades 14 approach each other to cut the residual material. The shear blades 14 will move away from the product, reducing damage to the product itself and improving the effect of cutting the residual material.

[0044] The implementation principle of Example 1 is as follows: during operation, the worker places the product on the mounting plate 11. Under the action of the first drive member 5, the product is driven to move closer to the shearing blades 14. When the residual material is inserted between the two shearing blades 14, the second drive member 10 drives the two shearing blades 14 closer to each other, thereby completing the shearing of the residual material. The two shearing blades 14 are reset under the action of the reset spring 22 and the second drive member 10. The sheared residual material falls into the collection box 4, thereby facilitating subsequent continuous shearing work. This design can make the residual material more efficiently sheared, improve the efficiency of the worker, and ensure that the cutting effect of each product is the same, ensuring the effect of the cut product.

[0045] Example 2:

[0046] Reference Figure 5 A shearing device for cleaning excess material from the surface of injection molded products. The device differs from Example 1 in that the second drive member 10 includes a rotating shaft 27 disposed at the end of the shear block 7 away from the shear blade 14. The rotating shaft 27 is cylindrical. Two drive seats 24 are fixed to the shear seat 8. The drive seats 24 are U-shaped and are respectively disposed on either side of the shear blade 14. A drive chute 28 is provided on the sidewall of the drive seat 24. The drive chute 28 is tilted downward in a direction away from the shear blade 14. After rotation, the drive chute 28 slides in the drive chute 28 to drive the switches of the two shear blocks 7. The shear seat 8 has a lifting slot 29. A slider 25 is slidably connected in the lifting slot 29. The slider 25 is a rectangular block. The shear block 7 is rotatably connected to the slider 25. A drive spring 26 is fixed to the bottom of the lifting slot 29 to drive the slider 25 upward. A support block 30 is fixed to the upper end of the shear block 7. The support block 30 is a rectangular block and has a function of supporting the product. A stretching bar 23 is fixed between the two shearing blocks 7. The stretching bar 23 is elastic and is used to eject the remaining material after shearing.

[0047] The working principle of Example 2 is as follows: during operation, under the action of the first driving member 5, the product is brought into contact with the support block 30, and the residual material is inserted between the two shearing blades 14. The product is then pushed downward, and under the action of the rotating shaft 27 and the driving slot 16, the two shearing blades 14 are brought closer together, thereby achieving the effect of shearing the residual material. After shearing is completed, the two shearing blades 14 are reset under the action of the driving spring 26, straightening the stretching bar 23. Under the action of the stretching bar 23, the residual material is pulled away from the two shearing blades 14. The first driving member 5 can simultaneously drive the positioning, installation and shearing of the product, thereby reducing the convenience of residual material cutting and improving the efficiency of cutting multiple residual materials at the same time.

[0048] The above are all preferred embodiments of the present application, and are not intended to limit the scope of protection of the present application. Therefore, any equivalent changes made based on the structure, shape, and principle of the present application should be included in the scope of protection of the present application.
