Description

Technical Field

[0001] The present invention relates to the technical field of die casting, and specifically to a forming die for a rope saw cutting polyurethane wear-resistant rubber ring and a using method thereof. Background Technique

[0002] When cutting marble, the polyurethane rubber strip technology constitutes a key component. These polyurethane rubber strips usually have good physical properties, high wear resistance and fatigue resistance to ensure that the rubber strips can be installed on the rope saw guide wheel to protect the guide wheel from being damaged by the diamond wire when cutting marble plates. Its design purpose is to provide a smooth surface and utilize the physical properties and wear-resistant characteristics of the polyurethane rubber strip to reduce the damage of the rope saw guide wheel by the diamond wire during high-speed operation and maintain the cutting accuracy. Therefore, during the production process, a corresponding circular die for the rubber strip is usually made according to the shape and diameter of the guide wheel of the customer, and then the circular wear-resistant rubber strip is produced by means of polyurethane casting, and then finely processed to the required size by a CNC lathe.

[0003] However, when the existing casting device casts the circular die, as the polyurethane prepolymer is continuously injected into the die through the casting port, the polyurethane prepolymer needs to continuously move to the side far from the circular die. Since the die is in an arc state, more power is required for the polyurethane prepolymer to flow, which slows down the flow rate of the polyurethane prepolymer. When rapid casting is required, the polyurethane prepolymer may start to cool and demold the die before it is evenly distributed in the die, resulting in surface defects of the die. At the same time, the unevenly distributed rubber strips may have problems such as insufficient wear resistance, frequent replacement of polyurethane rubber strips, reduced cutting accuracy of stone, derailment of the rubber strip, and weakened tensile strength during use.

[0004] In view of the above problems, there is an urgent need for innovative design on the original basis. Summary of the Invention

[0005] The purpose of the present invention is to provide a forming die for a rope saw cutting polyurethane wear-resistant rubber ring and a using method thereof to solve the problem in the above background technique that when rapid casting is required, the polyurethane prepolymer may start to cool and demold the die before it is evenly distributed in the die.

A movable plate is connected to the surface of the casting machine table through an electric telescopic rod. A rotating gear is installed on the surface of the casting machine table through a motor. Mounting blocks are fixed on the casting machine table at the front and rear ends of the casting mold;

[0007] A tooth block is provided on the outer side of the movable plate, and a moving block is provided inside the movable plate. A convex block one is installed on the inner side of the moving block. An activity module is provided inside the movable plate. One side of the activity module close to the casting mold is provided with a first movable rod and a second movable rod. And a first sliding groove is opened inside the activity module. A first spring is installed inside the first sliding groove, and a first sliding block is movably installed inside the first sliding groove.

[0008] Preferably, an elastic airbag one is connected and installed at one end of the first movable rod inside the activity module. An elastic airbag two is connected and installed at one end of the second movable rod inside the activity module. And the elastic airbag one and the elastic airbag two are mutually communicated through a hose. And one end of the first movable rod close to the outer mold is set to be cylindrical. The second movable rod is fixedly connected with the first sliding block, and the first sliding block is connected with the first spring.

[0009] Preferably, one end of the second movable rod close to the outer mold is set to be arc-shaped, and the second movable rod and the convex block three are on the same horizontal plane. And the convex block three and the second movable rod are set to be the same arc shape. A sealing ring is provided between the upper inner mold, the lower inner mold and the outer mold.

[0010] Preferably, a pressure spring is connected and installed on the activity module. And the activity module forms an elastic structure inside the movable plate through the pressure spring. And one end of the activity module located inside the movable plate is in contact with the arc-shaped end of the convex block one. At the same time, the activity modules are equidistantly arranged on the movable plate.

[0011] Preferably, the rotating gear meshes with the tooth block on the outer side of the movable plate. And two rotating gears are symmetrically arranged about the vertical center of the casting machine table. And the movable plate is in the shape of a quarter circle when viewed from above.

[0012] Preferably, the upper end of the electric telescopic rod is slidably installed in a groove opened at the bottom of the movable plate. And a column is limit slidably installed on the casting machine table. And a convex block two is fixedly installed at the upper end of the column. At the same time, the upper end of the column is arranged inside the movable plate.

[0013] Preferably, two columns are symmetrically arranged at the first bump, and a first connecting rod is fixed between the two columns, and the first connecting rod passes through a moving groove opened on the first bump.

[0014] Preferably, the arc end of the second bump fits with one end of the movable module located inside the movable plate, and a blowing pipeline is installed inside the movable module through a second connecting rod, and a rotating gear is installed on the second connecting rod.

[0015] Preferably, a second sliding groove is opened on the inner wall of the movable module, and a second spring is connected and installed inside the second sliding groove, and the second spring is connected with a second sliding block, and a moving rack is connected and installed on the second sliding block, and the moving rack meshes with the rotating gear.

[0016] Preferably, the method includes the following steps:

[0017] S1: During use, the casting mold is installed on the casting machine table through a fixing member, and then the movable top plate pushes the upper inner mold to be clamped with the lower inner mold inside the outer mold, and is sealed through a set sealing ring. After the clamping is completed, injection is carried out into the mold through the casting port;

[0018] S2: During casting, the rotating gear meshes with the toothed block to drive the movable plate to rotate reciprocally, so that the moving block periodically impacts the mounting block, driving the second movable rod to be extruded by the third bump, thereby pushing the first movable rod to impact the surface of the outer mold, generating vibration, and the position relationship between the first bump and the movable module changes, so that the second movable rod periodically contacts the third bump, thereby ensuring that the impact force is the same as the flow direction of the polyurethane prepolymer;

[0019] S3: When casting and cooling, the electric telescopic rod pushes the whole movable plate to move upward, so that the second movable rod and the third bump are not on the same horizontal line, thereby stopping the vibration impact of the first movable rod on the casting mold. At the same time, the second bump on the column abuts against the moving rack at this time, and then drives the offset of the blowing pipeline through the moving rack, so as to increase the cooling area of the casting mold;

[0020] S4: After cooling is completed, the electric telescopic rod drives the movable plate to reset, and through the movement of the movable plate, the first movable rod impacts the outer mold again to assist the casting mold to demold.

[0021] Compared with the prior art, the beneficial effects of the present invention are:

[0022] 1. First, by changing the traditional long strip casting rubber strip into an annular casting mold, and then for the rubber strip produced according to the present invention, since it is circular when produced, it can ensure that there is no tensile rebound stress during use, thus greatly reducing the possibility of the rubber strip derailing and enhancing the tensile strength. Moreover, because it is a circular mold, processing is easier, and it is also easier to match the guide wheel during installation, with a relatively high fitting precision, ensuring the fit between the rubber strip and the guide wheel, thereby guaranteeing the fitting precision between the rubber strip and the cutting saw, improving the overall precision and cutting precision. Also, due to the high fitting precision and closer fit, the wear rate is reduced, improving the wear resistance of the product, extending the service life of the rubber strip, and reducing the production cost of the enterprise;

[0023] 2. Further, by arranging a moving block that moves reciprocally on the outer side of the casting mold, during the continuous reciprocating movement of the moving block, through the second movable rod arranged inside it, it periodically impacts the first convex block on the outer mold, so that during the casting process, an external force towards the flowing direction of the polyurethane prepolymer is continuously applied to the outer mold, and then the polyurethane prepolymer inside can fill the inside of the casting mold faster during the casting process, enabling the polyurethane prepolymer to quickly and effectively fill the mold, preventing uneven distribution of the polyurethane prepolymer due to insufficient power;

[0024] 3. Even further, by pushing the movable plate to change its position through an electric telescopic rod, the second movable rod on the movable plate no longer contacts the third convex block, and the second convex block on the column periodically pushes the moving rack inside the movable module, so that the moving rack reciprocates inside the movable module. The reciprocating moving rack drives the blowing pipe to deflect up and down with the second connecting rod as the shaft end in the movable module, enabling the casting mold to cover a wider area during the cooling process, fully cooling the internal mold, and then being able to better complete the casting and demolding of the mold.

Detailed implementation manners

[0037] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0038] Please refer to Figures 1-11, the present invention provides a technical solution: a forming mold and a using method for a rope saw to cut a polyurethane wear-resistant rubber ring, including a casting machine table 1, on which a movable top plate 2 is connected through a hydraulic cylinder. An annular casting mold 3 is installed at the upper end of the casting machine table 1. The casting mold 3 includes an outer mold 31, an upper inner mold 32 and a lower inner mold 33. Fixing holes 35 are equally angularly arranged on the upper inner mold 32 and the lower inner mold 33. A buckle 34 is arranged on the outer mold 31, and convex blocks three 20 are equally angularly arranged on the surface of the outer mold 31. A movable plate 5 is connected to the surface of the casting machine table 1 through an electric telescopic rod 18. A rotating gear 17 is installed on the surface of the casting machine table 1 through a motor 16. Mounting blocks 4 are fixed on the casting machine table 1 at the front and rear ends of the casting mold 3;

[0039] A tooth block 6 is arranged on the outer side of the movable plate 5, and a moving block 7 is arranged inside the movable plate 5. A convex block one 8 is installed on the inner side of the moving block 7. An active module 12 is arranged inside the movable plate 5. An active rod one 13 and an active rod two 14 are arranged on the side of the active module 12 close to the casting mold 3. A first sliding groove 1403 is opened inside the active module 12. A first spring 1404 is installed inside the first sliding groove 1403. A first sliding block 1402 is movably installed inside the first sliding groove 1403.

[0040] As an implementation manner of the present invention, an elastic airbag one 1301 is connected and installed at one end of the active rod one 13 located inside the active module 12. An elastic airbag two 1401 is connected and installed at one end of the active rod two 14 located inside the active module 12. The elastic airbag one 1301 and the elastic airbag two 1401 are mutually communicated through a hose 19. One end of the active rod one 13 close to the outer mold 31 is set to be cylindrical. The active rod two 14 is fixedly connected to the first sliding block 1402, and the first sliding block 1402 is connected to the first spring 1404;

[0041] The elastic airbag one 1301 exchanges gas with the elastic airbag two 1401 through the hose 19. Then, the shape of the airbag is correspondingly changed by the flow of the gas, so as to push the active rod one 13 and the active rod two 14 to move in position through the deformation of the airbag;

[0042] As an implementation manner of the present invention, one end of the active rod two 14 close to the outer mold 31 is set to be arc-shaped, and the active rod two 14 and the convex block three 20 are on the same horizontal plane. The convex block three 20 and the active rod two 14 are set to be the same arc shape. A sealing ring is arranged between the upper inner mold 32 and the lower inner mold 33 and the outer mold 31;

[0043] Through the abutment between the top arc-shaped movable rod two 14 and the convex block three 20, the movable rod two 14 moves towards the inside of the movable module 12, and then squeezes the elastic airbag two 1401 inside the movable module 12. Through the conduction of gas, the movable rod one 13 is pushed out of the movable module 12 and impacts the surface of the external mold 31, thereby providing a certain external power to the internal polyurethane prepolymer and accelerating the circulation.

[0044] 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. The inner end of the movable module 12 located on the inner side of the movable plate 5 is fitted with the arc-shaped end of the convex block one 8. At the same time, the movable modules 12 are arranged at equal intervals on the movable plate 5. The rotating gear 17 meshes 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 table 1. When viewed from above, the movable plate 5 is in the shape of a quarter-circle arc.

[0045] The rotating gear 17 continuously deflects driven by 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 perform reciprocating motion. Thus, the moving block 7 on the movable plate 5 periodically impacts the mounting block 4, changing the position of the moving block 7 inside the movable plate 5, and further changing the positional relationship between the convex block one 8 and the movable module 12.

[0046] 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. A column 9 is installed on the casting machine table 1 with limited sliding. The upper end of the column 9 is fixedly installed with a convex block two 10. At the same time, the upper end of the column 9 is arranged inside the movable plate 5. Two columns 9 are symmetrically arranged at the convex block one 8. A connecting rod one 11 is fixed between the two columns 9, and the connecting rod one 11 passes through the moving groove 81 opened on the convex block one 8;

[0047] By setting the electric telescopic rod 18 to push the movable plate 5 to move up and down, the contact position between the convex block two 10 at the upper end of the column 9 and the movable module 12 is changed, so that the convex block two 10 contacts the moving rack 1503 inside the movable module 12. At the same time, the convex block two 10 moves left and right synchronously with the convex block one 8 through the connecting rod one 11.

[0048] As an implementation manner of the present invention, the arc-shaped end of the second bump 10 is attached to one end of the movable module 12 located inside the movable plate 5. A blowing pipe 15 is installed inside the movable module 12 through a second connecting rod 1501, and a rotating gear 1502 is installed on the second connecting rod 1501. A second sliding groove 1505 is formed on the inner wall of the movable module 12, and a second spring 1506 is connected and installed inside the second sliding groove 1505. The second spring 1506 is connected to a second sliding block 1504. At the same time, a moving rack 1503 is connected and installed on the second sliding block 1504, and the moving rack 1503 meshes with the rotating gear 1502;

[0049] The second bump 10 moves synchronously with the first bump 8 through the provided second connecting rod 1501. Furthermore, the second bump 10 periodically presses against the moving rack 1503, and drives the rotating gear 1502 to rotate reciprocally through the movement of the moving rack 1503, so that the rotating gear 1502 drives the blowing pipe 15 to move up and down, and cools the casting mold 3 more efficiently.

[0050] As an implementation manner of the present invention, the method includes the following steps:

[0051] S1: When in use, the casting mold 3 is installed on the casting machine table 1 through a fixing member. Subsequently, the movable top plate 2 pushes the upper inner mold 32 to be clamped with the lower inner mold 33 inside the outer mold 31, and is sealed through the provided sealing ring. After the clamping is completed, the mold interior is injected through the casting port;

[0052] S2: When casting, the rotating gear 17 meshes with the tooth block 6 to drive the movable plate 5 to rotate reciprocally, so that the moving block 7 periodically impacts the mounting block 4, driving the second movable rod 14 to be squeezed by the third bump 20, thereby pushing the first movable rod 13 to impact the surface of the outer mold 31, generating vibration. And due to the change in the positional relationship between the first bump 8 and the movable module 12, the second movable rod 14 periodically contacts the third bump 20, so as to ensure that the impact force is the same as the flow direction of the polyurethane prepolymer;

[0053] S3: When casting and cooling, the electric telescopic rod 18 pushes the whole movable plate 5 to move upward, so that the second movable rod 14 and the third bump 20 are not on the same horizontal line, thereby stopping the vibrating impact of the first movable rod 13 on the casting mold 3. At the same time, the second bump 10 on the column 9 is in contact with the moving rack 1503 at this time, and further drives the offset of the blowing pipe 15 through the moving rack 1503, so as to increase the cooling area of the casting mold 3;

[0054] 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 first movable rod 13 impacts the outer mold 31 again to assist the casting mold 3 in demolding.

[0055] Working principle: When using the forming mold of this guide wheel rubber strip, first install the casting mold 3 on the casting machine table 1 through the fixing holes, and install the upper inner mold 32 in the casting mold 3 on the movable top plate 2. Subsequently, 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 clamped with each other inside the outer mold 31, sealed through the provided sealing ring, and fixed by the buckle 34. Then, the polyurethane prepolymer is injected into the casting mold 3 through the casting port. At this time, the motor 16 drives the rotating gear 17 to rotate reciprocally, meshes with the tooth block 6 outside the movable plate 5, and drives the movable plate 5 to move reciprocally on the casting machine table 1;

[0056] During the casting process, through the continuous reciprocating movement of the movable plate 5, the second movable rod 14 slidably installed on the movable module 12 inside the movable plate 5 is extruded by the third convex block 20 provided on the surface of the outer mold 31. As a result, the second movable rod 14 moves towards the inside of the movable module 12. At the same time, the second movable rod 14 extrudes the second elastic airbag 1401 connected to the rear side. The second elastic airbag 1401 deforms after being externally extruded, and the gas inside is transmitted to the first elastic airbag 1301 through the hose 19. The first elastic airbag 1301 expands due to the gas and pushes the first movable rod 13 to move towards the outside of the movable module 12. The front cylindrical head of the first movable rod 13 moving outward impacts the surface of the outer mold 31 obliquely under the push of the first elastic airbag 1301, thereby providing an external force in the flowing direction of the polyurethane prepolymer, enabling the polyurethane prepolymer to always maintain activity, reducing the possibility of polyurethane prepolymer accumulation, and the moving block 7 on the movable plate 7 continuously impacts the mounting blocks 4 at both the front and rear ends of the casting machine table 1 during the movement. When moving in the flowing direction of the polyurethane prepolymer, at this time, the first convex block 8 on the moving block 7 presses against the tail end of the movable module 12, making the front part of it located outside the movable plate 5, so that the second movable rod 14 can contact the third convex block 20. When the moving block 7 abuts against the mounting block 4 at the rear end of the casting machine table 1, under the action of the movable plate 5, the moving block 7 deflects in position, causing the first convex block 8 to disengage from the tail end of the movable module 12, so that the movable module 12 returns to the inside of the movable plate 5 again, and the second movable rod 14 on the movable module 12 no longer contacts the third convex block 20 during the return process, so that the first movable rod 13 no longer impacts the outer mold 31, preventing the internal polyurethane prepolymer from flowing back due to the reaction force;

[0057] After the casting is completed, the electric telescopic rod 18 pushes the movable plate 5 to move upward as a whole. During the upward movement of the movable plate 5, the second convex block 10 at the upper end of the column 9 installed on the casting machine table 1 will abut against the moving rack 1503 inside the ascending movable module 12. The arc-shaped second convex block 10 will push the moving rack 1503 to move forward, so that the moving rack 1503 meshes with the rotating gear 1502, and the rotating rotating gear 1502 drives the blowing pipeline 15 to change its position through the second connecting rod 1501. And when the moving block 7 abuts against the mounting block 4 at the rear end of the casting machine table 1, the second convex block 10 and the first convex block 8 synchronously disengage from the tail end of the movable module 12, so that the moving rack 1503 resets under the action of the second spring 1506, thus restoring the blowing pipeline 15. Each impact will change the position of the blowing pipeline 15, so that the blowing pipeline 15 can cool the casting mold 3 at more angles, so that the internal polyurethane prepolymer can be better cast into shape;

[0058] After the cooling is completed, the electric telescopic rod 18 drives the movable plate 5 to reset again, repeats the movement process during casting, and assists the casting mold 3 to demold through the impact of the first movable rod 13, which is convenient for the staff to take the materials.

6. The forming die for a rope saw to cut a polyurethane wear-resistant rubber ring according to claim 5, characterized in that: A second sliding groove (1505) is opened on the inner wall of the movable module (12). A second spring (1506) is connected and installed inside the second sliding groove (1505). The second spring (1506) is connected to a second sliding block (1504). At the same time, a moving rack (1503) is connected and installed on the second sliding block (1504). The moving rack (1503) meshes with the rotating gear (1502).

7. A method for using a forming mold for a rope saw to cut a polyurethane wear-resistant rubber ring, using the forming mold described in claim 6, characterized in that: The method includes the following steps: S1: During use, the casting mold (3) is installed on the casting machine table (1) through a fixing member. Subsequently, the movable top plate (2) pushes the upper inner mold (32) to be clamped with the lower inner mold (33) inside the outer mold (31), and is sealed through the provided sealing ring. After the clamping is completed, the mold interior 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 reciprocally, so that the moving block (7) periodically impacts the mounting block (4), driving the second movable rod (14) to be squeezed by the third convex block (20), thereby pushing the first movable rod (13) to impact the surface of the outer mold (31) to generate vibration. Due to the change in the positional relationship between the first convex block (8) and the movable module (12), the second movable rod (14) periodically contacts the third convex block (20), thereby ensuring that the impact force is the same as the flow direction of the polyurethane prepolymer; S3: When casting and cooling, the electric telescopic rod (18) pushes the entire movable plate (5) to move upward, so that the second movable rod (14) and the third convex block (20) are not on the same horizontal line, thereby stopping the vibration impact of the first movable rod (13) on the casting mold (3). At the same time, the second convex block (10) on the column (9) is in contact with the moving rack (1503) at this time, and then drives the offset of the blowing pipe (15) through the moving rack (1503), increasing the cooling area of the casting mold (3). S4: After the cooling is completed, the electric telescopic rod (18) drives the movable plate (5) to reset again, and through the movement of the movable plate (5), the first movable rod (13) impacts the outer mold (31) again to assist the casting mold (3) in demolding.
