Description

Technical Field

[0001] This utility model relates to the field of grinding technology, and in particular to a splicable silicone mold and a molding die for the splicable silicone mold. Background Technology

[0002] Grinding is involved in the manufacturing processes of glass, ceramics, diamonds, and chips. Currently, mechanized grinding is generally carried out using a surface grinder. A grinding pad is installed on the surface grinder, and then the grinding materials for these products are ground.

[0003] In double-sided / single-sided grinding processes, surface grinders typically have large table areas for efficiency and stability. Optical glass commonly uses circular table surfaces with diameters of Φ930mm-Φ1160mm, while silicon carbide typically uses surfaces larger than Φ1200mm. This necessitates that the abrasive materials used on the grinding table meet these specifications. Furthermore, the grinding pad manufacturing process requires silicone molds to create molds for the abrasive materials. Therefore, the production of grinding pads necessitates the creation of silicone molds with diameters of Φ930mm or even larger than Φ1200mm to meet the demands of the production process.

[0004] Existing methods for preparing silicone molds all involve pressing using large silicone mold presses (over 600 tons) with a diameter of Φ1200-1400mm. However, existing methods for manufacturing silicone molds have the following drawbacks:

[0005] 1. Large silicone mold pressing machines are required, but they have very limited applications and are generally not equipped by silicone factories. Moreover, the production process is very complicated and requires large overhead cranes and sufficient space.

[0006] 2. A large silicone mold pressing machine is required, which needs to produce molding dies (usually steel dies used to press the silicone mold into shape). However, the processing cost of large steel dies is very high (requiring sufficient precision). If ultra-large CNC machine tools are used to prepare steel dies or ultra-large injection molding machines are used to prepare silicone, such equipment and production methods are high-energy-consuming and violate the requirements of energy conservation and emission reduction.

[0007] 3. Due to the high cost of steel molds, most manufacturers produce a set of steel molds with fixed dimensions, such as Φ930mm or Φ1200mm. This means that most manufacturers can only press one type of silicone mold, which cannot meet the needs of silicone molds of various sizes, such as large or small sizes.

[0008] Therefore, existing technologies need to be improved. Utility Model Content

[0009] In view of the shortcomings of the prior art, the purpose of this utility model is to provide a splicable silicone mold, which is designed to make small-sized silicone molds, and then splice them to form silicone molds of various large sizes to produce grinding pads of different specifications, while saving the cost of steel film and pressing machine.

[0010] To achieve the above objectives, this utility model discloses a splicable silicone mold, which includes a silicone body, at least one first splicing edge and at least one second splicing edge disposed on the edge of the silicone body;

[0011] The surface of the silicone body is provided with multiple grouting grooves;

[0012] The first splicing edge is provided with a first mortise and tenon joint, and the second splicing edge is provided with a second mortise and tenon joint;

[0013] The first splicing edge of one splicable silicone mold and the second splicing edge of another splicable silicone mold can be connected by splicing the first tenon and the second tenon.

[0014] In some embodiments, the silicone body is fan-shaped, and the two sides containing the radii of the fan shape are the first splicing side and the second splicing side, respectively.

[0015] In some embodiments, the silicone body is rectangular, and the first splicing edge and the second splicing edge are adjacent or opposite edges of the rectangle.

[0016] In some embodiments, the silicone body is rectangular, and the edges of the rectangular silicone body are sequentially provided with a first splicing edge, a second splicing edge, and a third splicing edge.

[0017] In some embodiments, the first tenon and mortise includes a protruding strip extending outward from the first splice edge;

[0018] The second tenon includes an inwardly notch on the second splicing edge, and the protrusion can be fitted into the notch.

[0019] In some embodiments, the first tenon and mortise portion further includes a locking groove formed on the protrusion;

[0020] The second tenon also includes a locking protrusion provided on the wall of the notch, which can engage with the locking groove.

[0021] In some embodiments, a boss is provided at the intersection of two adjacent first splicing edges of the silicone body.

[0022] In some embodiments, the bottom edge of the grouting groove is chamfered.

[0023] In some embodiments, the grouting groove is a trapezoidal groove that is wider at the top and narrower at the bottom.

[0024] This utility model also proposes a molding die for a splicable silicone mold, wherein the molding die is used to manufacture the aforementioned splicable silicone mold.

[0042] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0043] It should be noted that all directional indicators (such as up, down, left, right, front, back, etc.) in this utility model embodiment are only used to explain the relative positional relationship and movement of each component in a certain specific posture (as shown in the figure). If the specific posture changes, the directional indicator will also change accordingly.

[0044] Furthermore, in this utility model, descriptions involving "first," "second," etc., are for descriptive purposes only and should not be construed as indicating or implying their relative importance or implicitly specifying the number of technical features indicated. Therefore, a feature defined with "first" or "second" may explicitly or implicitly include at least one of those features.

[0045] Please refer to Figures 1 to 3This utility model proposes a splicable silicone mold 100, including a silicone body 10, at least one first splicing edge 20 and at least one second splicing edge 30 disposed on the edge of the silicone body 10. The first splicing edge 20 is used to splice with the second splicing edge 30 of another silicone mold 100, and the second splicing edge 30 is used to splice with the first splicing edge 20 of another silicone mold 100.

[0046] The silicone body 10 can be in various shapes such as rectangle, circle, and ellipse. The silicone body 10 has at least two sides for splicing, one of which is a first splicing side 20 and the other is a second splicing side 30. When the silicone body 10 has multiple sides, multiple first splicing sides 20 and multiple second splicing sides 30 can be provided accordingly.

[0047] The surface of the silicone body 10 is provided with multiple injection grooves 40. These grooves 40 are used to inject raw material when making a grinding pad using the silicone mold 100 of this invention. After the raw material is formed, demolding yields the grinding pad. The injection grooves 40 correspond to the formation of multiple grinding protrusions on the grinding pad. The multiple injection grooves 40 on the surface of the silicone body 10 can be distributed in an array. For example... Figure 3 As shown, there is a grid 41 between two adjacent grouting grooves 40 on the silicone body 10. After the grinding pad is obtained by mold making, the grid 41 will form regular grooves on the grinding pad. These grooves will play the role of grinding liquid flowing in and carrying out grinding debris during the grinding process.

[0048] Preferably, the total height of the connectable silicone mold 100 of this invention is about 4-6mm, and more preferably 5mm. The depth of the grouting groove 40 is about 1.6-2.0mm, and more preferably 1.8mm.

[0049] like Figure 3 As shown, the first splicing edge 20 is provided with a first tenon 50, and the second splicing edge 30 is provided with a second tenon 60. The first splicing edge 20 of one splicable silicone mold 100 and the second splicing edge 30 of another splicable silicone mold 100 can be spliced ​​and connected through the first tenon 50 and the second tenon 60. Figure 3 In the middle, the left and right splicable silicone molds 100 are spliced ​​together. They are spliced ​​together by the second tenon 60 provided on the second splicing edge 30 of the left splicable silicone mold 100 and the first tenon 50 provided on the first splicing edge 20 of the right splicable silicone mold 100. Then, high viscosity glue is injected into the gap reserved at the tenon joint position to achieve the splicing connection of multiple silicone molds 100.

[0050] Because the silicone mold 100 of this utility model can be spliced, it can be made into a small-sized silicone mold 100, such as a square mold of 400*400mm. This way, it can be produced by ordinary and commonly used pressing machines, which reduces the production difficulty. At the same time, the size of the steel mold is also greatly reduced, the production cost of the steel mold is greatly reduced, and it can be used for all purposes.

[0051] For products with a diameter of Φ1200mm or less, a 3x3 combination of 400*400mm square silicone molds can meet all application requirements. After assembly, the rectangles can be cut into circles. For products with a diameter of Φ1200mm or more, additional parts can be added as needed to meet all requirements. Alternatively, the silicone molds can be infinitely combined to accommodate larger product sizes.

[0052] The splicing position of the silicone mold 100 of this utility model adopts the following... Figure 3 The mortise and tenon structure shown allows the edges of the two silicone molds 100 to interlock. Compared to two silicone molds 100 that directly contact each other using their sidewalls without a mortise and tenon structure, the mortise and tenon structure of this invention significantly increases the contact area between the two silicone molds 100. This results in a higher adhesive strength when glue is injected at the mortise and tenon joint during the subsequent splicing process. With the assistance of suitable jigs, the mortise and tenon structure significantly reduces the difficulty of splicing and improves splicing efficiency. Simultaneously, it allows the seam to be controlled within a set range, ensuring the flatness and consistency of the silicone. Furthermore, the mortise and tenon structure means that the direction of the adhesive force at the splicing position of the two silicone molds 100 is no longer a single left-right direction, but multiple directions such as left-right and up-down. Therefore, during demolding, due to the increased force direction and area, the splicing position of the two silicone molds 100 is less likely to tear.

[0053] In one embodiment, the silicone body 10 of the splicable silicone mold 100 of this invention is rectangular, and in another embodiment, the first splicing edge 20 and the second splicing edge 30 are adjacent sides of the rectangle. When the first splicing edge 20 and the second splicing edge 30 are adjacent sides of the rectangle, they can be spliced ​​and combined along the length and width directions of the silicone mold 100.

[0054] Alternatively, the first splicing edge 20 and the second splicing edge 30 are opposite sides of the rectangle. When the first splicing edge 20 and the second splicing edge 30 are located on adjacent sides of the rectangle, they can be spliced ​​together along the length of the silicone mold 100.

[0055] Example 1, please refer to Figures 1 to 8In Embodiment 1, the silicone body 10 of the splicable silicone mold 100 is rectangular, and the edges of the rectangular silicone body 10 are sequentially provided with a first splicing edge 20, a second splicing edge 30, and a third splicing edge 30. For example... Figure 1 As shown, the top and right sides of the rectangular silicone body 10 are first splicing edges 20, and the bottom and left sides are second splicing edges 30. First tenon-and-mortise joints 50 are provided on the two first splicing edges 20, and second tenon-and-mortise joints 60 are provided on the two second splicing edges 30. This arrangement uses multiple sheets of... Figure 1 The single silicone mold 100 shown can be assembled into silicone molds of various specifications and sizes. For example, two single silicone molds 100 can be assembled into... Figure 4 The double silicone mold 100 assembly shown is as follows. Figure 4 The first splicing edge 20 of the left-side single silicone mold 100 is spliced ​​with the second splicing edge 30 of the right-side single silicone mold 100; if four single silicone molds 100 are used, they can be spliced ​​together to form a shape like... Figure 5 The four silicone molds 100 shown are assembled. Figure 4 The first splicing edge 20 of the upper left single silicone mold 100 is spliced ​​with the second splicing edge 30 of the upper right single silicone mold 100; the second splicing edge 30 of the upper left single silicone mold 100 is spliced ​​with the first splicing edge 20 of the lower left single silicone mold 100; and the second splicing edge 30 of the upper right single silicone mold 100 is spliced ​​with the first splicing edge 20 of the lower right single silicone mold 100. The rectangular silicone body 10 of Embodiment 1 can also be constructed by splicing together nine single silicone molds 100 in a 3x3 grid.

[0056] Specifically, such as Figures 6 to 8 As shown, in Embodiment 1, the first tenon 50 includes a protruding strip 51 extending outward from the first splicing edge 20, and the second tenon 60 includes a notch 61 extending inward from the second splicing edge 30. The protruding strip 51 can be fitted into the notch 61. In this embodiment, the protruding strip 51 is located at the lower part of the first splicing edge 20, forming an L-shaped protrusion structure, and the notch 61 is located at the lower part of the second splicing edge 30, forming an inverted L-shaped notch structure. In this way, the L-shaped protrusion structure can extend into the inverted L-shaped notch structure, so that the upper and lower walls and side walls of the two L-shaped structures fit together, forming a tenon structure. Then, the mating surfaces of the two L-shaped structures are glued together.

[0057] Preferably, the first tenon 50 further includes an engaging groove 52 formed on the protrusion 51; the second tenon 60 further includes an engaging protrusion 62 provided on the wall of the notch 61, the engaging protrusion 62 being able to engage with the engaging groove 52. Thus, after gluing, due to the engaging action of the engaging protrusion 62 and the engaging groove 52 themselves, plus the adhesive effect of the glue, the first splicing edge 20 and the second splicing edge 30 of the two silicone molds 100 are more firmly connected and less likely to detach.

[0058] Please refer to Figure 2 Preferably, a boss 21 is provided at the intersection of two adjacent first splicing edges 20 of the silicone body 10. The boss 21 facilitates positioning during splicing.

[0059] Please continue to refer to this. Figure 7 , Figure 8 In this embodiment, the bottom edge of the grouting groove 40 is provided with a chamfer 42. The chamfer 42 facilitates demolding during the process of making the grinding pad.

[0060] Preferably, the grouting groove 40 in this embodiment is a trapezoidal groove (not shown) that is larger at the top and smaller at the bottom. That is, the grouting groove 40 on the silicone body 10 has a trapezoidal structure with a small bottom and a large opening. This design is also to facilitate demolding after the grout has solidified during the grinding pad manufacturing process.

[0061] Example 2, as Figure 9 As shown, the difference between the splicable silicone mold 100 disclosed in this embodiment and that in embodiment one is that the silicone body 10 in embodiment two is fan-shaped, and the two sides containing the radii of the fan shape are the first splicing side 20 and the second splicing side 30, respectively. The first splicing side 20 is still provided with the first tenon 50, and the second splicing side 30 is still provided with the second tenon 60. In this way, multiple silicone molds 100 of embodiment two can be spliced ​​into a semi-circular or circular silicone mold to make a semi-circular or circular grinding pad.

[0062] This utility model also proposes a molding die (not shown) for a splicable silicone mold, which can produce the aforementioned splicable silicone mold 100. This molding die is generally a steel mold and can consist of an upper mold and a lower mold. The upper or lower mold has corresponding structures for processing the silicone body 10, first splicing edge 20, second splicing edge 30, grouting groove 40, first tenon 50, second tenon 60, etc., which are part of the splicable silicone mold 100.

[0063] The present invention relates to a splicable silicone mold 100 and a molding mold. By setting a silicone body 10, a first splicing edge 20 and a second splicing edge 30, a first tenon 50 is provided on the first splicing edge 20 and a second tenon 60 is provided on the second splicing edge 30, two or more silicone molds 100 can be spliced ​​together through the first tenon 50 and the second tenon 60. In this way, a single silicone mold 100 can be made into a relatively small size, and then spliced ​​together to make other silicone molds 100 of various large sizes, so as to make grinding pads of different sizes, while saving the cost of the corresponding molding mold (steel mold).

[0064] The above description is merely an example to clearly illustrate the present utility model and is not intended to limit the patent scope of the present utility model. It is impossible to exhaustively list all the embodiments here. All equivalent structural transformations made using the content of the technical solution of the present utility model under the concept of the present utility model, or direct / indirect applications in other related technical fields, are included within the patent protection scope of the present utility model.
