Description

Technical Field

[0001] The invention relates to the technical field of mold manufacturing, in particular to a dispersion disk manufacturing mold. Background Art

[0002] Dispersing disc is mainly used for crushing, mixing and grinding liquids, emulsions and liquid-solid materials such as coatings, pigments, dyes, paints, inks, foods, adhesives, medicines and daily chemicals. It is a common accessory for mechanical equipment such as dispersers, grinders, crushers, mixers and emulsifiers.

[0003] At present, the dispersion disc is usually divided into single-sided teeth and double-sided teeth. The following problems may occur when processing the double-sided teeth dispersion disc:

[0004] 1. Use a bending machine to bend all teeth one by one, but this production method makes it difficult to control the tooth height and angle of each tooth, the dynamic balance accuracy of the product is low, and the center of gravity often deviates from the axis, causing large vibration and noise during use.

[0005] 2. The double-sided teeth of the dispersion disc need to be turned over after the dispersion teeth on one side are completed before the dispersion teeth on the other side can be made. This production method is cumbersome and inefficient.

[0006] For this reason, we propose a dispersion disc manufacturing mold. Summary of the Invention

[0042] The specific embodiments of the present invention will be described below with reference to the accompanying drawings.

[0043] The present invention will be further described in detail below with reference to the accompanying drawings.

[0044] The overall scheme of the dispersion disc manufacturing die of the present invention is as follows: Figure 1 As shown, the details are as follows: the mold consists of an upper mold assembly 1, a lower mold assembly 2, a base component 3, a guide component 4 and a limiting component 5.

[0045] like Figure 1-Figure 2 As shown, the base component 3 is used to fix and support the lower mold assembly 2. The base component 3 includes a base 21 and a lower pad 23. The base 21 is fixedly connected to the lower clamping plate 18, the first lower pad 19 and the lower mold base 20 through multiple pillars.

[0046] In this embodiment, the upper mold assembly 1 is fixedly connected to the punch press to achieve up and down movement, and the stamping sheet 27 is placed between the upper mold assembly 1 and the lower mold assembly 2. At least one side of the upper mold assembly 1 and the lower mold assembly 2 is provided with multiple guide components 4 for guiding and positioning, and at least one side of the upper mold assembly 1 and the lower mold assembly 2 is provided with a positioning pin 26 for positioning the workpiece, and at the same time, at least one side of the upper mold assembly 1 and the lower mold assembly 2 is provided with a limiting component 5 for limiting up and down movement.

[0047] like Figure 1 As shown, the dispersion disk manufacturing mold of this embodiment includes an upper mold assembly 1 and a lower mold assembly 2 that can move relative to each other. The main structures of the upper mold assembly 1 and the lower mold assembly 2 are distributed in a mirror-symmetrical manner. A bending template is provided in the middle position of the opposite side of the upper mold assembly 1 and the lower mold assembly 2 for clamping and positioning the workpiece when the mold is closed;

[0048] In addition, there are several stamping and bending mechanisms 13 distributed along the circumference of the upper and lower bending templates. The stamping and bending mechanisms 13 include a bending punch 32 and a floating block 33 that are respectively located in the upper die assembly 1 and the lower die assembly 2 and on the same vertical line; the floating block 33 is connected to the side wall of the workpiece close to a bending insert 34 that can move up and down and press and fix the root of the part to be bent; the bending punch 32 is connected to a bending insert 31 that moves simultaneously with the upper and lower die assemblies and bends the end of the part to be bent of the workpiece; the bending punches 32 and floating blocks 33 in the multiple stamping and bending mechanisms 13 located on the same horizontal plane are distributed at intervals, which can realize bending in two directions at the same time, thereby improving bending efficiency.

[0049] Figure 2 The diagram schematically shows the open state of the stamping and bending die. Figure 2As shown, the mold includes an upper mold base 6 and a lower mold base 20. An upper mold pressing plate 11 is provided below the upper mold base 6, and an upper clamping plate 8 is provided between the upper mold base 6 and the upper mold pressing plate 11. A first upper pad 7 is generally provided between the upper mold base 6 and the upper clamping plate 8, and a second upper pad 9 and an upper stop plate 10 are generally provided between the upper mold pressing plate 11 and the upper clamping plate 8.

[0050] A lower die plate 15 is provided above the lower die base 20, a lower clamping plate 18 is provided between the lower die base 20 and the lower die plate 15, a first lower pad 19 is generally provided between the lower die base 20 and the lower clamping plate 18, and a second lower pad 17 and a lower stop plate 16 are generally provided between the lower die plate 15 and the lower clamping plate 18. When the mold is in the open state, the distance between the upper clamping plate 8 and the second upper pad 9, and the distance between the lower clamping plate 18 and the second lower pad 17 can be set according to the bending height of the disc teeth, while the distance between the upper die plate 11 and the lower die plate 15 is generally adjusted according to the stamping working conditions.

[0051] In this embodiment, since the dispersion disc is a double-sided tooth bending structure, and the tooth shape, bending angle and bending height on both sides are consistent, the overall structure of the upper mold assembly 1 and the lower mold assembly 2 are similar, and the bending forming mechanism is a mirror image relationship, the working process and principle are consistent, the following is combined Figure 2 、 Figure 3 The internal structure of the upper die assembly 1 is described in detail. In the upper die assembly 1, the upper bending template 12 is installed in the core cavity of the upper die pressing plate 11, and the upper clamping plate 8 is equipped with a stamping and bending mechanism 13. A backing plate return spring 30 and a floating block return spring 22 are installed in the hole of the upper die base 6. The backing plate return spring 30 passes through the upper die base 6, the first upper backing plate 7, and the upper clamping plate 8 in order from top to bottom. The backing plate return spring 30 is located directly above the second upper backing plate 9 and is connected to the second upper backing plate 9 at its bottom. The floating block return spring 22 passes through the upper die base 6, the first upper backing plate 7, the upper clamping plate 8, and the second upper backing plate 9 in order from top to bottom. The floating block return spring 22 is located directly above the floating block 33 and is connected to the floating block 33 at its bottom. Furthermore, the upper die base 6, the first upper backing plate 7, and the upper clamping plate 8 are rigidly connected, and the second upper backing plate 9, the upper stop plate 10, and the upper die pressing plate 11 are rigidly connected.

[0052] In this embodiment, Figure 3 Shows Figure 2 Some parts in the machine are used for stamping and bending. Figure 3As shown, the dispersed tooth stamping and bending mechanism 13 comprises a bending punch 32, a bending insert 31, a bending template, a bending insert 34, and a floating block 33. The bending punch 32 is mounted in a punch hole in the lower clamping plate 18, passing through the lower clamping plate 18, the second lower pad 17, the lower stop plate 16, and the lower die plate 15. The arcuate groove of the bending punch 32 is used to mount the bending insert 31, and the two are movably connected. A threaded hole is provided at the end where the bending punch 32 and the bending insert 31 meet, and this threaded connection secures the bending insert 31 to the corresponding position of the bending punch 32.

[0053] A float 33 is provided directly above the bending punch 32. The float 33 is mounted in the float hole in the upper stop plate 10 and passes through the upper die plate 11. A bending insert 34 is provided between the upper die plate 11 and the upper bending template 12. The upper bending template 12 has shaped grooves evenly distributed along the circumference. The number of shaped grooves is the same as the number of bending inserts 34, which are used to mount the bending inserts 34. The upper and lower bending templates can be adjusted according to the contour of the stamping sheet 27. The upper bending template 12 and the float 33 jointly limit the bending inserts 34.

[0054] In this embodiment, Figure 4 The figure schematically shows the clamping state of the stamping and bending die. Figure 4 As shown, when using the mold for processing, the dispersion disk stamping sheet 27 is placed between the upper bending template 12 and the lower bending template 14, that is, on the top of the lower bending template 14. The operation uses the stamping and bending structure to process the sheet material. During stamping, the guide column 24 cooperates with the guide cylinder 29 to ensure the position of the upper and lower die punches. First, the upper clamping plate 8 is fitted with the second upper pad 9, and then fitted with the upper die pressing plate 11 and the lower die pressing plate 15. The stamping and bending mechanism 13 of the upper die assembly 1 and the lower die assembly 2 begin to work together. The bending punch 32 first passes through the bending template on the other side, and the bending block 31 contacts the tooth surface of the sheet material. Driven by the bending punch 32, the bending block 31 bends the tooth surface, and finally the bent sheet material contacts the bending insert 34 on the other side. The bending insert 31 and the bending insert 34 cooperate with each other to stamp and bend the dispersed tooth surface of the sheet material. At the same time, the floating block 33 moves along the stamping direction, which plays a buffering and limiting role in the bending process, ensuring that the tooth surface forming is uniform and stable to prevent scratches. Finally, the upper limit pin 28 contacts the lower limit pin 25, completing the stamping and bending of the upper and lower tooth surfaces of the dispersion disc. During mold separation, the backing plate return spring 30 and the floating block return spring 22 act to slowly separate the mold and the dispersion disc, reducing vibration and noise and preventing scratches on the formed tooth surfaces.

[0055] In another embodiment, Figure 5-Figure 7 The working process of the stamping and bending mechanism 13 is schematically shown. Figure 5As shown, before stamping, the bending block 31 is provided with an arc-shaped notch with an entrance angle of α on one side close to the workpiece. Figure 6 As shown, the matching surface of the bending insert 34 and the bending insert block 31 is provided with a slope angle β corresponding to the angle of the arc notch. Through the effective cooperation of the combined structure of the bending insert block 31 and the bending insert 34, the position of the bending insert block 31 relative to the tooth surface can be appropriately adjusted during the stamping process so that the bent tooth surface is formed in place and the bending angle is 90°, thereby ensuring the bending accuracy, preventing the tooth shape from rebounding after bending, and meeting the interchangeability requirements. Figure 5 As shown, a gap with an angle of φ is provided between the arc groove and the bending entry block 31. Since the bending entry block 31 is movably connected to the bending punch 32, the bending entry block 31 can be rotated to a certain angle after stamping, so as to facilitate the demolding of the dispersion disc after molding, avoid the mold and the tooth surface from being stuck when the dispersion disc is demolded, reduce vibration and noise, reduce scratches on the tooth surface, and ensure the surface appearance quality of the stamped tooth surface.

[0056] Among them, when the α angle range is 85°-88°, the bending block rotates along the arc groove of the bending punch when the mold is closed, and acts on the tooth surface together with the bending insert. The entrance angle of the bending block and the slope angle of the bending insert on the same plane cooperate with each other, and the relative planes of the two bend the tooth surface into shape. This structure can compensate for the rebound angle after the tooth shape is bent, so that the bending angle meets the use requirements (the bending angle of this dispersion disk is 90°).

[0057] β angle range 92°-96°

[0058] The Φ angle range is 3°-6°. The back space of the bending block during parting after the tooth shape is formed facilitates demoulding and prevents scratches on the tooth surface during demoulding.

[0059] The three angles can be adjusted appropriately to meet actual needs according to the bending angle requirements.

[0060] One-step stamping and bending forming of double-sided teeth of dispersion disc + design of new die stamping and bending mechanism 13.

[0061] The double-sided teeth of the dispersion disc can be stamped and bent in one step, which greatly improves the bending efficiency. The consistency of the tooth shape and the bending accuracy of the dispersion teeth are effectively controlled, so that the dispersion disc is subjected to balanced force during application, the dynamic balance accuracy of the product is improved, and vibration and noise are improved.

[0062] The double-sided teeth of the dispersion disc in the present invention are formed by one-time stamping and bending, and a new type of dispersion disc production mold is designed;

[0063] The processing is simple, the stability is high, and it has the following effects.

[0064] 1. A special stamping and bending independent mechanism design for a dispersion disc manufacturing die, including a new stamping and bending forming structure of a bending punch 32, a bending insert 31, a bending insert 34 and a floating block, can effectively ensure the bending accuracy and tooth profile consistency of the dispersion teeth, and effectively improve the dynamic balance accuracy of the product.

[0065] 2. In the stamping and bending mechanism 13, the bending insert 31 is flexibly connected to the bending punch 32. The position of the bending insert 31 relative to the tooth surface can be adjusted appropriately during the stamping process to ensure the stamping is in place. In addition, while ensuring interchangeability, it prevents scratches on the surface of the dispersion disc and facilitates mold separation and replacement.

[0066] 3. The upper and lower dies of the stamping die are equipped with independent stamping mechanisms. Several stamping mechanisms are evenly distributed along the circumference, which can stamp and bend the double-sided teeth around the dispersion disc in one step, thereby improving the bending efficiency and effectively ensuring the consistency of the tooth shape.

[0067] ① Solve the problems of the existing technology 1, such as the consistency of tooth shape, high bending teeth, difficult to control bending angle and low dynamic balance accuracy when the teeth are bent one by one;

[0068] ② Solve the problem of low efficiency of double-sided tooth turning and bending of the dispersion disk in the prior art 1.
