Description

Technical Field

[0001] The invention relates to the technical field of mold casting, in particular to a molding mold for cutting polyurethane wear-resistant rubber rings with a rope saw and a use method thereof. Background Art

[0002] When cutting marble, polyurethane rubber strip technology constitutes a key component. These polyurethane rubber strips usually have good physical properties, high wear resistance and fatigue resistance, so as to ensure that the rubber strips can be installed on the wire saw guide wheel to protect the guide wheel from being damaged by the diamond wire when cutting marble slabs. Its design purpose is to provide a smooth surface and utilize the physical properties and wear resistance of polyurethane rubber strips to reduce the wire saw guide wheel from being damaged by the diamond wire when it is running at high speed during the cutting process and maintain the cutting accuracy. Therefore, in the production process, the corresponding rubber strip circular mold is usually made according to the shape and diameter of the customer's guide wheel, and then the round wear-resistant rubber strip is produced by polyurethane casting, and then fine-processed to the required size by CNC lathe.

[0003] However, when the existing casting device is casting a circular mold, as the polyurethane prepolymer is continuously injected into the mold through the casting port, the polyurethane prepolymer needs to continuously move to the side away from the circular mold. Since the mold is in an arc-shaped state, the polyurethane prepolymer requires more power during the circulation process, which slows down the flow rate of the polyurethane prepolymer. When rapid casting is required, the mold may be cooled and demolded before the polyurethane prepolymer is evenly distributed in the mold, resulting in surface defects of the mold. At the same time, the unevenly distributed rubber strips may have insufficient wear resistance during use, frequent replacement of polyurethane rubber strips, reduced stone cutting accuracy, rubber strip derailment, and reduced tensile strength.

[0004] In view of the above problems, it is urgent to carry out innovative design based on the original one. Summary of the invention

[0016] Compared with the prior art, the present invention has the following beneficial effects: 1. First, by changing the traditional long strip casting rubber strip into a circular ring-shaped casting mold, the rubber strip produced according to the present invention is circular in shape, so it can be ensured that there is no tensile rebound stress during use, thereby greatly reducing the possibility of the rubber strip derailing and improving the tensile strength. In addition, because it is a circular mold, it is easier to process and easier to match the guide wheel during installation. The matching accuracy is relatively high, ensuring the fit between the rubber strip and the guide wheel, thereby ensuring the matching accuracy between the rubber strip and the cutting saw, thereby improving the overall accuracy and cutting accuracy. Because of the high matching accuracy, the fit is tighter and the wear rate is reduced, thereby improving the wear resistance of the product, extending the service life of the rubber strip, and reducing the production cost of the enterprise; 2. Furthermore, a reciprocating moving block is arranged on the outer side of the casting mold, so that the moving block periodically collides with the convex block 1 on the outer mold through the movable rod 2 arranged inside the moving block during the continuous reciprocating motion, so that during the casting process, the external force in the direction of the polyurethane prepolymer flow is continuously applied to the outer mold, thereby enabling the internal polyurethane prepolymer to fill the inside of the casting mold faster during the casting process, so that the polyurethane prepolymer can quickly and effectively fill the mold, and prevent the uneven distribution of the polyurethane prepolymer due to insufficient power; 3. Furthermore, the movable plate is pushed to change its position by the electric telescopic rod, so that the movable rod 2 on the movable plate is no longer in contact with the protrusion 3, and the movable rack inside the movable module is periodically pushed by the protrusion 2 on the column, so that the movable rack reciprocates inside the movable module. The reciprocating movable rack meshes with the rotating gear, driving the blowing pipe to deflect up and down in the movable module with the connecting rod 2 as the axis end, so that the casting mold covers a wider area during the cooling process, so that the internal mold is fully cooled, and the casting and demolding of the mold can be better completed.

[0022] As an embodiment of the present invention, a pressure spring 1201 is connected and installed on the movable module 12, and the movable module 12 forms an elastic structure inside the movable plate 5 through the pressure spring 1201, and the inner end of the movable module 12 located on the movable plate 5 is in contact with the arc-shaped end of the protrusion 8, and the movable module 12 is arranged at an equal distance on the movable plate 5, and the rotating gear 17 is meshed with the tooth block 6 on the outer side of the movable plate 5, and two rotating gears 17 are symmetrically arranged about the vertical center of the casting machine 1, and the movable plate 5 is in the shape of a quarter circle when viewed from above.

[0023] The rotating gear 17 is continuously deflected under the drive of the motor 16, and then meshes with the tooth block 6 on the outer side of the movable plate 5, driving the movable plate 5 to reciprocate, so that the moving block 7 on the movable plate 5 periodically collides with the mounting block 4, so that the position of the moving block 7 inside the movable plate 5 changes, thereby changing the positional relationship between the protrusion 8 and the movable module 12.

[0024] As an embodiment of the present invention, the upper end of the electric telescopic rod 18 is slidably installed in the groove opened at the bottom of the movable plate 5, and the casting machine table 1 is slidably installed with a column 9 at the upper limit position, and the upper end of the column 9 is fixedly installed with a protrusion 10, and the upper end of the column 9 is arranged inside the movable plate 5, and the column 9 is symmetrically provided with two protrusions 8, and a connecting rod 11 is fixed between the two columns 9, and the connecting rod 11 passes through the movable groove 81 opened on the protrusion 8; The movable plate 5 is pushed up and down by the electric telescopic rod 18, thereby changing the contact position between the protrusion 2 10 at the upper end of the column 9 and the movable module 12, so that the protrusion 2 10 contacts the movable rack 1503 inside the movable module 12, and at the same time, the protrusion 2 10 moves left and right synchronously with the protrusion 1 8 through the connecting rod 1 11.

[0025] As an embodiment of the present invention, the arc-shaped end of the second protrusion 10 fits with one end of the movable module 12 located inside the movable plate 5, and the inside of the movable module 12 is provided with a blowing pipe 15 through the second connecting rod 1501, and the second connecting rod 1501 is provided with a rotating gear 1502, and the inner wall of the movable module 12 is provided with a second sliding groove 1505, and the inside of the second sliding groove 1505 is connected and installed with a second spring 1506, and the second spring 1506 is connected to the second sliding block 1504, and the sliding block 1504 is connected and installed with a moving rack 1503, and the moving rack 1503 is meshed with the rotating gear 1502; The protrusion 10 moves synchronously with the protrusion 1 8 through the connecting rod 1501, and then the protrusion 10 will periodically press the moving rack 1503, and drive the rotating gear 1502 to rotate back and forth through the movement of the moving rack 1503, so that the rotating gear 1502 drives the blowing pipe 15 to deflect up and down, so as to cool the casting mold 3 more efficiently.

[0026] As an embodiment of the present invention, the method comprises the following steps: S1: When in use, the casting mold 3 is mounted on the casting machine table 1 through the fixing parts, and then the movable top plate 2 pushes the upper inner mold 32 to engage with the lower inner mold 33 inside the outer mold 31, and seals with the provided sealing ring. When the engagement is completed, the inside of the mold is injected through the casting port; S2: During casting, the rotating gear 17 meshes with the tooth block 6 to drive the movable plate 5 to rotate back and forth, so that the moving block 7 periodically collides with the mounting block 4, driving the movable rod 2 14 to be squeezed by the protrusion 3 20, thereby pushing the movable rod 1 13 to collide with the surface of the outer mold 31, generating vibration, and changing the positional relationship between the protrusion 1 8 and the movable module 12, so that the movable rod 2 14 periodically contacts with the protrusion 3 20, thereby ensuring that the impact force is the same as the flow direction of the polyurethane prepolymer; S3: When casting and cooling are performed, the electric telescopic rod 18 pushes the movable plate 5 to move upward as a whole, so that the movable rod 2 14 and the protrusion 3 20 are not on the same horizontal line, thereby stopping the vibration impact of the movable rod 13 on the casting mold 3. At the same time, the protrusion 2 10 on the column 9 abuts against the movable rack 1503, and then the blowing pipe 15 is driven to deflect through the movable rack 1503, so that the cooling area of ​​the casting mold 3 is increased; S4: After the cooling is completed, the electric telescopic rod 18 drives the movable plate 5 to reset, and through the movement of the movable plate 5, the movable rod 13 hits the outer mold 31 again to assist the casting mold 3 in demoulding.

[0027] Working principle: When using the molding mold of the guide wheel rubber strip, firstly, the casting mold 3 is installed on the casting machine 1 through the fixing hole, and the upper inner mold 32 in the casting mold 3 is installed on the movable top plate 2, and then the movable top plate 2 drives the upper inner mold 32 to move downward, so that the upper inner mold 32 and the lower inner mold 33 are mutually engaged inside the outer mold 31, and are sealed by the provided sealing ring, and fixed by the lock buckle 34, and then the polyurethane prepolymer is injected into the casting mold 3 through the casting port, and at this time, the motor 16 drives the rotating gear 17 to reciprocate, meshes with the tooth block 6 outside the movable plate 5, and drives the movable plate 5 to reciprocate on the casting machine 1; During the casting process, through the continuous reciprocating motion of the movable plate 5, the movable rod 2 14 slidably installed on the movable module 12 inside the movable plate 5 is squeezed by the protrusion 3 20 set on the surface of the outer mold 31, so that the movable rod 2 14 moves toward the inside of the movable module 12, and at the same time, the movable rod 2 14 squeezes the elastic airbag 2 1401 connected to the rear side. The elastic airbag 2 1401 is deformed after being squeezed by the outside, and the internal gas is transmitted to the elastic airbag 1 1301 through the hose 19. The elastic airbag 1 1301 is expanded by the gas, thereby pushing the movable rod 13 to move toward the outside of the movable module 12. The front end cylindrical head of the movable rod 13 moving outward is pushed by the elastic airbag 1 1301 to obliquely impact the surface of the outer mold 31, thereby providing an external force in the flow direction of the polyurethane prepolymer, so that the polyurethane prepolymer can always maintain its activity, reducing the polymerization The possibility of urethane prepolymer accumulation is eliminated, and the moving block 7 on the movable plate 5 continuously collides with the mounting blocks 4 at the front and rear ends of the casting machine 1 during movement. When moving in the direction of the flow of the polyurethane prepolymer, the protrusion 1 8 on the moving block 7 presses the tail end of the movable module 12, so that its front end is located outside the movable plate 5, so that the movable rod 2 14 can contact with the protrusion 3 20. When the moving block 7 abuts against the mounting block 4 at the rear end of the casting machine 1, under the action of the movable plate 5, the moving block 7 is shifted in position, so that the protrusion 1 8 is separated from the tail end of the movable module 12, so that the movable module 12 returns to the inside of the movable plate 5, so that the movable rod 2 14 on the movable module 12 no longer contacts with the protrusion 3 20 during the recovery process, so that the movable rod 1 13 no longer impacts the outer mold 31, preventing the internal polyurethane prepolymer from being subjected to the reaction force and flowing back. When the casting is completed, the electric telescopic rod 18 pushes the movable plate 5 to move upward as a whole. In the process of the movable plate 5 moving upward, the protrusion 2 10 on the upper end of the column 9 installed on the casting machine 1 will abut against the moving rack 1503 inside the rising movable module 12, and the arc-shaped protrusion 2 10 will push the moving rack 1503 to move forward, so that the moving rack 1503 and the rotating gear 1502 are meshed, so that the rotating rotating gear 1502 drives the blowing pipe 15 to change its position through the connecting rod 2 1501, and when the moving block 7 abuts against the mounting block 4 at the rear end of the casting machine 1, the protrusion 2 10 and the protrusion 1 8 are synchronously separated from the tail end of the movable module 12, so that the moving rack 1503 is reset under the action of the second spring 1506, so that the blowing pipe 15 is restored, and each collision will change the position of the blowing pipe 15, so that the blowing pipe 15 can cool the casting mold 3 at more angles, so that the internal polyurethane prepolymer can be better cast and formed; When the cooling is completed, the electric telescopic rod 18 drives the movable plate 5 to reset again, repeating the movement process during casting, and assisting the casting mold 3 to be demoulded through the impact of the movable rod 13, making it convenient for the staff to take the materials.

10. A method for using a forming mold for cutting polyurethane wear-resistant rubber rings with a wire saw, suitable for the forming mold described in claim 9, characterized in that: The method comprises the following steps: S1: When in use, the casting mold (3) is mounted on the casting machine table (1) via a fixing member, and then the movable top plate (2) pushes the upper inner mold (32) to engage with the lower inner mold (33) inside the outer mold (31), and seals the engagement with a provided sealing ring. When the engagement is completed, injection is performed into the interior of the mold through the casting port; S2: During casting, the rotating gear (17) and the tooth block (6) are meshed to drive the movable plate (5) to rotate back and forth, so that the moving block (7) periodically collides with the mounting block (4), driving the movable rod (14) to be squeezed by the protrusion (20), thereby pushing the movable rod (13) to collide with the surface of the outer mold (31), generating vibration, and changing the positional relationship between the protrusion (8) and the movable module (12), so that the movable rod (14) periodically contacts with the protrusion (20), thereby ensuring that the impact force is the same as the flow direction of the polyurethane prepolymer; S3: When casting and cooling are being performed, the electric telescopic rod (18) pushes the movable plate (5) to move upward as a whole, so that the movable rod 2 (14) and the protrusion 3 (20) are not on the same horizontal line, thereby stopping the vibration impact of the movable rod 1 (13) on the casting mold (3). At the same time, the protrusion 2 (10) on the column (9) abuts against the movable rack (1503), and then the displacement of the blowing pipe (15) is driven by the movable rack (1503), so that the cooling area of ​​the casting mold (3) is increased; S4: After the cooling is completed, the electric telescopic rod (18) drives the movable plate (5) to reset, and through the movement of the movable plate (5), the movable rod 1 (13) hits the outer mold (31) again to assist the casting mold (3) in demoulding.
