Abstract
Description
Technical Field
[0001] The present application relates to the technical field of diamond production, and in particular to a pouring mold for integrally forming polishing materials. Background Art
[0002] Rhinestones are also known as crystal diamonds and rhinestones. The main component of rhinestones is crystal glass, which is a kind of jewelry accessory obtained by cutting artificial crystal glass into diamond facets. This material is very popular because it is relatively economical and has a dazzling diamond-like visual effect. It is widely used in low- and medium-end jewelry design, so rhinestones are mainly processed in batches.
[0003] In the fully automatic production process of rhinestones, the processing of rhinestones needs to go through processes such as powder gluing, drilling, grinding, polishing, and cutting. Among them, the rhinestone polishing process requires the use of polishing materials to polish the rhinestone facets so that the rhinestone facets have a smoothness that meets the refraction requirements. In the prior art, the polishing material is solidified and formed by a mold, and then sleeved onto a rotating roller for polishing. Since the polishing material is obtained by solidification, its surface smoothness is not high, and the friction between it and the mold joint surface is relatively large. Considering the final yield of the polishing material obtained during the actual operation, it is usually formed separately in two stages, and the solidified polishing material is taken out of the mold by extrusion, and finally the two stages of polishing material are bonded. Although the mold and preparation method provided by the prior art can ensure that the polishing material is basically 100% obtained, in the actual operation process, a hydraulic press is required and two operators are equipped, which is time-consuming and has a high processing cost. In addition, the polishing material obtained by bonding has an unrepairable joint in the middle, resulting in the polishing of the rhinestones by the joint being unable to be well polished during the use of the polishing material, affecting the polishing yield of the rhinestones.

[0005] The present application provides a pouring mold for integrally forming a polishing material, comprising: a base, an outer cylinder, an inner liner, a first hanger, and a second hanger; one end of the outer cylinder is placed on the base, and the other end provides a fixing interface for the first hanger; the inner liner is placed on the second hanger, and the second hanger is placed on the base; a pouring space for the polishing material is reserved between the inner wall of the outer cylinder and the outer wall of the inner liner.
[0006] Specifically, one of the concepts of the present application is that, through the design of the mold structure, the polishing material can be taken out of the mold at one time by lifting, so that the polishing material can be demolded without hydraulic operation and splicing, thereby reducing the complexity of the demolding operation and improving the demolding efficiency.
[0007] Furthermore, the lining structure is a hollow cylindrical shape, and the smoothness level of its outer wall surface is higher than, or equal to ▽7. Through milling processing, the lining surface has a higher smoothness, which reduces the friction coefficient of the outer wall of the lining, facilitates demolding from the lining after the polishing material solidifies, and improves the success rate of demolding.
[0008] Furthermore, a taper from large to small is provided on the outer wall of the liner from the base toward the first hanging piece, and the taper is less than or equal to 1:800.
[0009] Specifically, another concept of the present application is that, through the tapered design of the outer wall of the lining, the polishing material has a slight inclination angle during the lifting and demolding process, providing demolding assistance during gravity lifting, and further improving the demolding success rate of the polishing material.
[0010] In some embodiments, the base includes a seat body and supporting feet, and the supporting feet are fixedly connected to the ground near the seat body; the seat body is constructed in a ring shape, and its mounting surface is sequentially provided with a sunken first step and a second step, and the accommodation radius of the second step is smaller than that of the first step; the first step is used for placing the outer cylinder through a clearance fit; the second step is used for placing the second hanger through a clearance fit.
[0011] Specifically, another concept of the present application is to provide installation interfaces for various components through a sunken step, so as to make the structure of the entire device more compact.
[0012] Furthermore, the second hanging member includes a bearing plate; the bearing plate is constructed in a ring shape, and a sunken third step is provided on its bearing surface, and the third step is used for placing the liner by means of clearance fit.
[0013] Furthermore, the second hanging member also includes an external plate, a hanging ring mounting hole is arranged in the middle of the external plate; the inner hole radius of the supporting plate is smaller than the inner hole radius of the seat body; the external plate includes a short side and a long side in its working plane, the short side is smaller than the inner hole radius of the supporting plate, and the long side is larger than the inner hole radius of the supporting plate.
[0014] Specifically, the external connecting plate is used to lift the bearing plate and the liner on the bearing plate, so as to remove the liner from the polishing material.
[0015] Furthermore, the external plate is configured as a rectangle with a raised step in the middle; in the short side direction of the external plate, the bottom and the external connecting surface of the step are configured as arcs, the arc of the bottom is clearance matched with the inner hole radius of the base, and the arc of the step is clearance matched with the inner hole radius of the supporting plate.
[0016] In some embodiments, the outer cylinder is a hollow shell, both ends of which extend outward from the cylinder surface to form an outwardly expanded annular mounting surface.
[0017] Furthermore, the first hanging member is structured in a disc shape, the outer wall radius of which is the same as the radius of the annular mounting surface expanded outwardly from the outer cylinder, and a hanging ring mounting hole is provided in the middle thereof.

[0019] Furthermore, the fixing interface is set as an internal threaded hole; the matching part between the first hanging piece and the outer tube is provided with an internal thread identical to the fixing interface; the outer tube and the first hanging piece are connected by detachable bolts.
[0020] In summary, the present application provides a pouring mold for the one-piece molding of polishing materials. Through the structural design of the base, outer cylinder, inner lining, first hanging piece, second hanging piece, etc., the polishing material can be removed from the pouring space through two lifting processes, which changes the traditional demolding method of the polishing material, reduces the difficulty of demolding the polishing material and the investment in production costs, so that the present application has at least the advantages of simple operation, low processing cost, good polishing material integrity, and high demolding success rate.

DETAILED DESCRIPTION
[0027] The following is combined with Figures 1 to 4 , a detailed description of this application is given.
[0028] In order to make the purpose, technical solution and advantages of the present application more clearly understood, the present application is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present application and are not used to limit the present application.
[0029] The present application provides a pouring mold for integrally forming polishing materials, which has at least the advantages of simple operation, low processing cost, good polishing material integrity, and high demoulding success rate.
[0030] See also Figure 1 Shown is a perspective view of a pouring mold for integrally forming a polishing material provided by an embodiment of the present application.
[0031] Specifically, after the assembly is completed, the pouring mold for integrally forming the polishing material provided by the present application is as follows: Figure 1 As shown, the first hanging member 40, the outer cylinder 20 and the base 10 and other components can be seen from the perspective view.
[0032] In order to understand the structure of the pouring mold provided by this application more clearly, please refer to Figure 2 Shown is a cross-sectional view taken along the A axis of a pouring mold for integrally forming a polishing material provided by another embodiment of the present application.
[0033] Specifically, during the polishing material pouring and molding operation, the base 10, the second hanging member 50, the outer cylinder 20 and the inner lining 30 components are placed in sequence to form a pouring space 70 between the inner wall of the outer cylinder 20 and the outer wall of the inner lining 30, and then the polishing material slurry is poured into the pouring space 70. After the slurry is completely solidified, the first hanging member 40 is installed through the fixed interface 21, and the first hanging member 40 is lifted through the lifting ring 60. Since the outer cylinder 20 is placed on the base 10 and connected to the first hanging member 40, the outer cylinder 20 can be lifted out from the solidified outer wall of the polishing material by lifting the first hanging member 40. Finally, the inner lining 30 placed on the second hanging member 50 is lifted out from the inner wall of the polishing material through the second hanging member 50, thereby completing the demoulding of the entire polishing material.
[0034] It is worth noting that, in actual operation, the order of lifting out the outer cylinder 20 and the inner liner 30 can be reversed.
[0035] Furthermore, the lining 30 is constructed as a hollow cylinder, and the smoothness level of its outer wall surface is higher than, or equal to ▽7. Through milling processing, the surface of the lining 30 has a higher smoothness, which reduces the friction coefficient of the outer wall of the lining 30, facilitates demolding from the lining 30 after the polishing material solidifies, and improves the success rate of demolding.
[0036] It is worth noting that the finish grade ▽7 is the lowest grade of the smooth surface, and a liner 30 with a higher finish grade can be selected according to the actual demoulding success rate of the actual polishing material. In theory, the higher the finish grade of the outer wall of the liner 30, the higher the demoulding success rate of the polishing material, and consequently, the higher the processing success of the liner 30.
[0037] Furthermore, the outer wall of the liner 30 is provided with a taper from large to small from the base 10 toward the first hanging member 40, and the taper is less than or equal to 1:800. Through the taper design of the outer wall of the liner 30, the polishing material has a slight inclination during the lifting and demoulding process, providing demoulding assistance during the gravity lifting process, and further improving the demoulding success rate of the polishing material.
[0038] For an explanation of the working principle of the pouring mold provided for this application, see Figure 3 Shown is a schematic diagram of the disassembly of a pouring mold for integrally forming a polishing material provided by another embodiment of the present application.
[0039] Specifically, the base 10 includes a base body 11 and a support foot 12, the support foot 12 is fixed to the ground near the base body 11; the base body 11 is annular in structure, and its mounting surface is sequentially provided with a sunken first step 13 and a second step 14, and the receiving radius of the second step 14 is smaller than the first step 13; the first step 13 is used to place the outer cylinder 20 through a clearance fit; the second step 14 is used to place the second hanging piece 50 through a clearance fit. The support foot 12 allows the base body 11 to have a certain height from the ground, which is convenient for operating the second hanging piece 50 during the hoisting process.
[0040] It is worth noting that the outer cylinder 20 and the second hanging piece 50 are both clearance-fitted with the base body 11 , that is, on the base 10 placed outside on the ground, the second hanging piece 50 is placed on the base body 11 through the sunken second step 14 , and then the outer cylinder 20 is placed on the first step 13 .
[0041] Furthermore, the second hanging member 50 includes a bearing plate 51; the bearing plate 51 is constructed in a ring shape, and a sunken third step 52 is provided on its bearing surface, and the third step 52 is used to place the liner 30 through clearance fitting.
[0042] It is worth noting that the inner liner 30 is also placed on the bearing plate 51 by means of clearance fit. After the bearing plate 51, the inner liner 30 and the outer cylinder 20 are placed, the adjacent surfaces of the three form a semi-enclosed space, namely the pouring space 70 mentioned in this application, so that the slurry can be poured into the pouring space 70.
[0043] In some embodiments, the outer cylinder 20 is a hollow shell, both ends of which extend outward from the cylinder surface to form an outwardly expanded annular mounting surface 22. The widened annular mounting surface 22 facilitates the placement, connection and fixation of the first hanging member 40.
[0044] Further, the first hanging member 40 is configured as a disk, the outer wall radius of which is the same as the radius of the annular mounting surface 22 of the outer cylinder 20, and the center thereof is provided with a hanging ring mounting hole 54. The first hanging member 40 is used to lift the outer cylinder 20 out of the polishing material.
[0045] It is worth noting that, during the pouring of the polishing material slurry, the first hanging member 40 is not installed to the outer cylinder 20. The first hanging member 40 is mainly used to hang the outer cylinder 20 out from the outer wall of the polishing material after the polishing material solidifies.
[0046] Furthermore, the fixing interface 21 is configured as an internal threaded hole; the matching portion between the first hanging piece 40 and the outer cylinder 20 is provided with an internal thread identical to the fixing interface 21; the outer cylinder 20 and the first hanging piece 40 are connected by detachable bolts.
[0047] After the outer cylinder 20 is lifted out by the first hanging member 40 , the detachable bolts can be removed to separate the first hanging member 40 from the outer cylinder 20 , and then the outer cylinder 20 can be used for the next polishing material slurry pouring operation.
[0048] For further information, see Figure 4 Shown is a perspective view of an external board 53 provided in yet another embodiment of the present application.
[0049] Furthermore, the second hanging member 50 also includes an external plate 53, and a hanging ring mounting hole 54 is arranged in the middle of the external plate 53; the inner hole radius of the supporting plate 51 is smaller than the inner hole radius of the seat body 11; the external plate 53 includes a short side 55 and a long side 56 in its working plane, and its short side 55 is smaller than the inner hole radius of the supporting plate 51, and its long side 56 is larger than the inner hole radius of the supporting plate 51.
[0050] Specifically, the external plate 53 is used to lift the supporting plate 51 and the liner 30 on the supporting plate 51 to remove the liner 30 from the polishing material.
[0051] Furthermore, the external plate 53 is configured to be rectangular in shape, with a raised step in the middle thereof; in the direction of the short side 55 of the external plate 53, the bottom and the external connecting surface of the step are configured to be arc-shaped, the arc of the bottom is clearance matched with the inner hole radius of the base 10, and the arc of the step is clearance matched with the inner hole radius of the supporting plate 51.
[0052] It is worth noting that the external plate 53 is not placed under the supporting plate 51 before the slurry is poured. After the slurry solidifies, the short side of the external plate 53, that is, the short side 55 direction, passes through the lining 30 and the supporting plate 51 in sequence, and then the plate body direction of the external plate 53 is twisted, so that the external plate 53 passes through the long side, that is, the long side 56 direction, to lock the supporting plate 51, thereby realizing the lifting of the supporting plate 51 and the lining 30 above the supporting plate 51.
[0053] The present application is described in detail above. The principles and implementation methods of the present application are described in detail using specific examples in the present application. The description of the above embodiments is only used to help understand the present application and its core ideas. It should be pointed out that, for ordinary technicians in this technical field, without departing from the principles of the present application, several improvements and modifications can be made to the present application, and these improvements and modifications also fall within the scope of protection of the claims of the present application.
