Description

Technical Field

[0001] The invention relates to the technical field of molds, in particular to a pressing mold. Background Art

[0002] Rubber polyurethane is a series of elastomeric materials containing a large number of carbamate groups on the main chain of the polymer. When rubber polyurethane is produced into required items, a pressing mold is usually used to process the rubber polyurethane material into the required workpiece. In order to increase the service life of the mold, the mold is usually subjected to wear-resistant treatment.

[0003] The existing patent (Announcement No.: CN212331615U) discloses a wear-resistant rubber polyurethane pressing mold, comprising a pressing table, the top of which is fixedly connected to a lower mold, both sides of the top of the pressing table are fixedly connected to columns, the outer sides of the two columns are slidably connected to sliding sleeves, a moving plate is fixedly connected between the two sliding sleeves, the bottom of the moving plate is fixedly connected to an upper mold, and a hydraulic cylinder is fixedly installed on the top of the moving plate. After molding, the motor drives the rotating disk to drive the rotating rod to rotate, and the cooperation between the rotating rod and the connecting block enables the ejector rod to lift the bottom plate, thereby ejecting the extruded parts upward from the lower mold, which is simple and convenient to operate, improves work efficiency and reduces labor costs, and solves the problem that the existing wear-resistant pressing mold is very inconvenient to remove after the rubber polyurethane is extruded, resulting in reduced work efficiency and increased labor costs.

[0004] In the process of using the above invention, the main problem solved is that the material can be ejected from the inside for easy unloading, but there is still a problem: in the manufacture of rubber polyurethane, some round objects need to be pressed. After pressing, burrs may appear on the top edge, which needs to be trimmed manually. At the same time, because the material is soft, it will easily appear on the top of the mold cavity, which will lead to the phenomenon of difficulty in demolding.

[0005] For this purpose, a pressing die is proposed. Summary of the invention

[0006] The purpose of the present invention is to provide a pressing mold. After the pressing is completed, the internal design of the upper mold and the lower mold can make demolding more convenient. At the same time, the burrs can be removed by moving the blade, which improves the work efficiency. The material can be unloaded through the sweeping rod, which further improves the speed of producing materials to solve the problems raised in the above background technology.

[0007] To achieve the above-mentioned purpose, the present invention provides the following technical solutions: a pressing mold, comprising a shell, a first hydraulic rod is fixedly connected at the center of the upper end of the shell, a cross plate is fixedly connected at the lower end of the first hydraulic rod, a support block is fixedly connected at the center of the lower end of the cross plate, an upper mold is slidably connected at the lower end of the support block, a workbench is arranged at the lower end of the shell, a first groove is provided on the upper end surface of the workbench, a lower mold is fixedly connected inside the first groove, a support plate is connected at the supporting foot of the lower end of the workbench, a second hydraulic rod is fixedly connected at the upper end of the support plate, a first circular hole is provided at the lower end of the first groove, the upper end of the second hydraulic rod is fixedly connected to the lower end of the lower mold through the first circular hole, and a cutting mechanism is provided on the left side of the inside of the first groove;

[0008] The cutting mechanism includes a first support rod, a first rotating wheel, a first protrusion, a first cavity, a T-shaped block, a first spring, a second groove, a moving wheel, a blade, a second circular hole, a stopper, a circle and an annular groove, the first support rod being fixedly connected to the left side of the lower end of the cross plate, a plurality of the first rotating wheels being fixedly connected to the right side of the first support rod, the annular groove being opened at the inner upper end of the workbench, the circle being rotatably connected to the inside of the annular groove, the first protrusion being rotatably connected to the outside of the circle, the stopper being fixedly connected to the outside of the circle, the first cavity being opened at the left side of the upper end of the circle, the T-shaped block being slidably connected to the inside of the first cavity, the blade being fixedly connected to the right side of the T-shaped block, the first spring being movably sleeved on the outside of the T-shaped block, the moving wheel being fixedly connected to the left side of the T-shaped block, the second groove being opened at the left upper end of the annular groove, the second groove being slidably connected to the moving wheel, and the second circular hole being opened on the left side of the workbench.

[0009] Because the material of rubber polyurethane is soft, some burrs will appear on the edges when it is pressed, so manual removal reduces the efficiency of the work;

[0010] When the raw material is put into the lower mold, the first hydraulic rod moves downward, the first hydraulic rod drives the cross plate to move downward, the cross plate drives the support block at the lower end to move downward, and the support block drives the upper mold to move downward until the upper mold moves to the first groove to press the material. At this time, the first hydraulic rod moves upward, driving the cross plate to move upward while driving the first support rod fixedly connected on the left side to move upward inside the circular hole. The first support rod moves upward and drives multiple first wheels to move upward. At this time, multiple first wheels push the first protrusion to slide at one time. Because the first protrusion is designed to be inclined, the rotating circle rotates inside the annular groove. When the rotating circle rotates, due to the second groove, it moves inward against the first rotating wheel. At this time, the first rotating wheel drives the T-shaped block to move inside the first cavity, and the T-shaped block drives the blade to move inward. When the first hydraulic rod moves to the top, the first rotating wheel returns to the inside of the second groove, and the first spring pushes the T-shaped block to move outward, retracts the blade, cuts the edge of the material in a circle, and completes the edge deburring. After the deburring is completed, the second hydraulic rod moves upward, driving the lower mold to move upward at the same time to push the material out.

[0011] Preferably, a second support rod is fixedly connected to the left side of the lower end of the cross plate, and a second rotating wheel is fixedly connected to the right side of the rod wall of the second support rod, a through hole is opened on the left side of the upper end surface of the workbench, and a second cavity is opened on the left side inside the workbench, a moving block is slidably connected to the inside of the second cavity, a second protrusion is fixedly connected to the left side of the moving block, a second spring is fixedly connected to the rear end of the moving block, a first sleeve is fixedly connected to the front end of the second cavity, a first piston is slidably connected to the inside of the first sleeve, a first air pipe is fixedly connected to the front end of the first sleeve, and the first air pipe is fixedly connected to the lower end of the first groove, a vent hole is opened inside the lower mold, a blocking block is fixedly connected to the lower end of the first groove, the blocking block matches the vent hole, and the number of the second rotating wheels is greater than the second protrusion.

[0012] When the second support rod moves downward, it moves against the second protrusion. Since the number of the second wheels is greater than the second protrusion, the second wheel can move the moving block to the back. When the second support rod moves upward, it can move the moving block to the front. The moving block drives the first piston to move forward inside the first sleeve. At this time, the pressure inside the first sleeve increases. When the second hydraulic rod drives the lower mold to move upward, the blocking block is separated from the vent hole. At this time, gas will enter the vent hole, which makes demolding easier. When the first support rod is moved out, the moving block is reset due to the action of the second spring.

[0013] Preferably, sliding grooves are provided on both left and right sides of the interior of the shell, and sliders are slidably connected to the interior of the two sliding grooves. A threaded rod is rotatably connected to the interior of the right sliding groove, and the threaded rod is threadedly connected to the interior of the slider, and a sweeping rod is fixedly connected to the lower end of the rod wall of the threaded rod.

[0014] When the cross plate moves upward, it drives the two sliders to move inside the corresponding slide grooves. When the slider on the right moves downward, it drives the threaded rod connected by the thread to rotate. When the threaded rod rotates, it drives the sweeping rod fixed at the bottom to move, so that the material can be unloaded.

[0015] Preferably, the inner side wall of the upper mold is fixedly connected with a first convex ball, the lower end of the outer side wall of the support block is provided with a third groove, the insides of multiple third grooves are fixedly connected with third springs, and the outer sides of multiple third springs are fixedly connected with second convex balls.

[0016] When the horizontal plate moves upward, it drives the supporting block upward. When the supporting block moves upward, it drives the second convex ball upward. At this time, due to the extrusion of the first convex ball, the second convex ball moves toward the inside of the third groove and squeezes the third spring. When it is misaligned with the first convex ball, the second convex ball moves outward under the tension of the third spring, so that a collision occurs and vibration is generated, and the demoulding effect of the top is better.

[0017] Preferably, the front ends of both sides of the horizontal plate are fixedly connected to the first telescopic rods, the insides of the four first telescopic rods are fixedly connected to the fourth springs, the lower ends of the four first telescopic rods are rotatably connected to a supporting plate, and the left and right sides of the front end bottom of the workbench are fixedly connected to limiting blocks.

[0018] When the sweeping rod pushes the material to the carrying plate, due to the increase in gravity, the carrying plate slowly descends under the action of the fourth spring. At this time, when the cross plate moves downward, when the rear side of the carrying plate passes the limit block, the two first telescopic rods at the rear end contract, causing the entire carrying plate to tilt and unload the material. When the cross plate moves upward, the carrying plate is reset.

[0019] Preferably, a second telescopic rod is fixedly connected to the left side of the lower end of the horizontal plate, a second sleeve is fixedly connected to the left side of the interior of the workbench, a second piston is slidably connected to the interior of the second sleeve, the second piston is fixedly connected to the lower end of the second telescopic rod, a second air pipe is fixedly connected to the lower right end of the second sleeve, and a nozzle is fixedly connected to the upper end of the second air pipe.

[0020] When the horizontal plate moves downward, the horizontal plate drives the second telescopic rod to move downward. When it moves to an appropriate position, it pushes the second piston to move downward, compresses the gas inside the second sleeve, and then sprays the gas inside the second sleeve from the nozzle through the second air pipe, so that the debris on the workbench can be removed.

[0021] Compared with the prior art, the present invention has the following beneficial effects:

[0022] 1. The horizontal plate can be moved up and down to drive the blade to circle around the edge of the mold to remove the hair from the edge of the pressed material, which reduces the workload of workers and improves production efficiency;

[0023] 2. The pressure at the bottom of the lower mold can be increased by moving the horizontal plate and the first piston, so that the internal air pressure is kept greater than the atmospheric pressure during demolding, which makes demolding easier;

[0024] 3. The sweeping rod on the right can be used to unload the material after pressing is completed, which reduces the demand for manpower and can greatly increase the pressing rate. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0036] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0037] Please refer to Figure 1 to Figure 2, the present invention provides a technical solution:

[0038] A pressing die, such as Figures 1 to 3 and Figures 6 to 8 and Fig. 9As shown, it comprises a shell 1, a first hydraulic rod 2 is fixedly connected at the center of the upper end of the shell 1, a cross plate 3 is fixedly connected to the outer surface of the lower end of the first hydraulic rod 2, a support block 4 is fixedly connected at the center of the lower end of the cross plate 3, an upper mold 6 is slidably connected to the outer surface of the lower end of the support block 4, a workbench 5 is arranged at the lower end of the shell 1, a first groove 7 is provided on the upper end surface of the workbench 5, a lower mold 9 is fixedly connected inside the first groove 7, a support plate 8 is connected to the support foot at the lower end of the workbench 5, a second hydraulic rod 11 is fixedly connected to the upper end of the support plate 8, a first circular hole 10 is provided at the lower end of the first groove 7, the upper end of the second hydraulic rod 11 passes through the first circular hole 10 and is fixedly connected to the lower end of the lower mold 9, a cutting mechanism 12 is arranged on the left side inside the first groove 7;

[0039] The cutting mechanism 12 includes a first support rod 1200, a first rotating wheel 1201, a first protrusion 1202, a first cavity 1203, a T-shaped block 1204, a first spring 1205, a second groove 1210, a moving wheel 1211, a blade 1206, a second circular hole 1207, a stopper 1212, a circle 1208 and an annular groove 1209. The first support rod 1200 is fixedly connected to the left side of the lower end of the horizontal plate 3, and the plurality of first rotating wheels 1201 are fixedly connected to the right side of the first support rod 1200. The annular groove 1209 is opened at the inner upper end of the workbench 5, and the circle 1208 is rotatably connected to the inside of the annular groove 1209. The first protrusion 1202 is rotatably connected to the outside of the circle 1208, the stopper 1212 is circularly fixedly connected to the outside of the circle 1208, the first cavity 1203 is opened at the left side of the upper end of the circle 1208, the T-shaped block 1204 is slidably connected to the inside of the first cavity 1203, the blade 1206 is fixedly connected to the right side of the T-shaped block 1204, the first spring 1205 is movably sleeved on the outside of the T-shaped block 1204, the moving wheel 1211 is fixedly connected to the left side of the T-shaped block 1204, the second groove 1210 is opened at the upper end of the left side of the annular groove 1209, the second groove 1210 is slidably connected to the moving wheel 1211, and the second circular hole 1207 is opened on the left side of the workbench 5;

[0040] During operation, when the raw material is placed in the lower mold 9, the first hydraulic rod 2 moves downward, the first hydraulic rod 2 drives the cross plate 3 to move downward, the cross plate 3 drives the support block 4 at the lower end to move downward, and the support block 4 drives the upper mold 6 to move downward until the upper mold 6 moves to the first groove 7. Because the first protrusion 1202 is connected to the circle 1208 for rotation, the circle 1208 will not rotate during the descent, and the material is pressed. At this time, the first hydraulic rod 2 moves upward. The first support rod 1200 fixedly connected on the left side moves upward inside the second circular hole 1207 while driving the horizontal plate 3 upward. The first support rod 1200 moves upward and drives the plurality of first rotating wheels 1201 to move upward. At this time, the plurality of first rotating wheels 1201 push the first protrusion 1202 to slide in turn. Under the action of the stopper 1212, the circle 1208 rotates inside the annular groove 1209. When the circle 1208 rotates, due to the arc-shaped design of the second groove 1210, the moving wheel 1211 moves inward. At this time, the moving wheel 1211 drives the T-shaped block 1204 to move inside the first cavity 1203. The T-shaped block 1204 drives the blade 1206 to move inward. When the first hydraulic rod 2 moves to the top, The moving wheel 1211 returns to the inside of the second groove 1210, and the first spring 1205 pushes the T-shaped block 1204 to move outward, retracting the blade 1206, cutting the edge of the material in a circle, and completing the edge deburring. After the deburring is completed, the second hydraulic rod 11 moves upward, driving the lower mold 9 to move upward at the same time, and ejecting the material. In this way, the edge of the material is directly cut off, which reduces the workload of people and improves production efficiency.

[0041] As an embodiment of the present invention, Figures 2 to 5 As shown, a second support rod 40 is fixedly connected to the left side of the lower end of the horizontal plate 3, and a second rotating wheel 38 is fixedly connected to the right side of the rod wall of the second support rod 40. A through hole 39 is opened on the left side of the upper end table of the workbench 5, and a second cavity 13 is opened on the left side of the interior of the workbench 5. A moving block 14 is slidably connected to the interior of the second cavity 13, and a second protrusion 15 is fixedly connected to the left side of the moving block 14. A second spring 37 is fixedly connected to the rear end of the moving block 14, and a first sleeve 16 is fixedly connected to the front end of the second cavity 13. A first piston 41 is slidably connected to the interior of the first sleeve 16. A first air pipe 17 is fixedly connected to the front end of the first sleeve 16. The first air pipe 17 is fixedly connected to the left side of the lower end of the first groove 7. A vent hole 18 is opened in the interior of the lower mold 9, and a blocking block 19 is fixedly connected to the lower end of the first groove 7. The blocking block 19 matches the vent hole 18, and the number of the second rotating wheels 38 is greater than the number of the second protrusions 15.

[0042] During extrusion, the gas at the bottom is almost squeezed out, which creates a pressure difference between the inside and the outside, making demolding more difficult;

[0043] During operation, when the second support rod 40 moves downward, it moves against the second protrusion 15. Since the number of the second rotating wheels 38 is greater than the second protrusion 15, the second rotating wheels 38 can move the moving block 14 to the back. When the second support rod 40 moves upward, the moving block 14 can be moved to the front. The moving block 14 drives the first piston 41 to move forward inside the first sleeve 16. At this time, the internal pressure of the first sleeve 16 increases. When the second hydraulic rod 11 drives the lower mold 9 to move upward, the blocking block 19 is separated from the vent 18. At this time, the gas will enter the vent 18, which ensures that the bottom pressure is the same as the external air pressure, making demolding easier. When the second support rod 40 is moved out, the moving block 14 is reset due to the action of the second spring 37, so that demolding is easier after the pressure is increased.

[0044] As an embodiment of the present invention, Figure 1 to Figure 2 As shown, the housing 1 has slide grooves 20 on both sides, and the two slide grooves 20 are slidably connected with sliders 21. The right slide groove 20 is rotatably connected with a threaded rod 22, and the threaded rod 22 is threadedly connected to the inside of the slider 21. The lower end of the rod wall of the threaded rod 22 is fixedly connected with a sweep rod 23.

[0045] After the internal parts are suppressed, they need to be moved away manually, which increases the manpower;

[0046] During operation, when the cross plate 3 moves upward, the cross plate 3 drives the two sliders 21 to move inside the corresponding slide grooves 20. When the slider 21 on the right moves downward, the threaded rod 22 connected by the thread is driven to rotate. When the threaded rod 22 rotates, it drives the sweeping rod 23 fixedly connected at the bottom to move, so that the material can be unloaded and the required manpower is reduced.

[0047] As an embodiment of the present invention, Figure 2 and Fig. 9 As shown, the inner side wall of the upper mold 6 is fixedly connected with a first convex ball 24, the lower end of the outer side wall of the support block 4 is provided with a third groove 25, the inner parts of the plurality of third grooves 25 are fixedly connected with third springs 26, and the outer sides of the plurality of third springs 26 are fixedly connected with second convex balls 27;

[0048] After pressing, the upper mold 6 is tightly connected to the material, which makes demoulding more difficult;

[0049] During operation, when the horizontal plate 3 moves upward, it drives the support block 4 to move upward. When the support block 4 moves upward, it drives the second convex ball 27 to move upward. At this time, due to the extrusion of the first convex ball 24, the second convex ball 27 moves toward the inside of the third groove 25 and squeezes the third spring 26. When it is misaligned with the first convex ball 24, the second convex ball 27 moves outward under the tension of the third spring 26, so that a collision occurs and vibration is generated, so that the demoulding effect of the top is better.

[0050] As an embodiment of the present invention, Figure 1 , Figure 2 and Figure 4 As shown, both sides of the front end of the horizontal plate 3 are fixedly connected to the first telescopic rods 28, the insides of the four first telescopic rods 28 are fixedly connected to the fourth springs 29, and the lower ends of the four first telescopic rods 28 are rotatably connected to the bearing plate 30, and the left and right sides of the front bottom of the workbench 5 are fixedly connected to the limit blocks 31;

[0051] If the material is pushed directly by the sweeping rod 23, the material may be damaged during unloading;

[0052] During operation, when the sweeping rod 23 pushes the material to the carrying plate 30, due to the increase in gravity, the carrying plate 30 slowly descends under the action of the fourth spring 29. At this time, when the cross plate 3 moves downward, when the rear side of the carrying plate 30 hits the two limit blocks 31, the two first telescopic rods 28 at the rear end contract, causing the entire carrying plate 30 to tilt and unload the material. When the cross plate 3 moves upward, the carrying plate 30 is reset, which can reduce damage to the material during unloading.

[0053] As an embodiment of the present invention, Figure 2 and Figure 3 As shown, a second telescopic rod 32 is fixedly connected to the left side of the lower end of the horizontal plate 3, a second sleeve 33 is fixedly connected to the left side of the interior of the workbench 5, a second piston 34 is slidably connected inside the second sleeve 33, the second piston 34 is fixedly connected to the lower end of the second telescopic rod 32, a second air pipe 35 is fixedly connected to the lower right end of the second sleeve 33, and a nozzle 36 is fixedly connected to the upper end of the second air pipe 35;

[0054] If there are debris on the upper end of the workbench 5, the debris may be brought in during pressing, which will cause the quality of the material to deteriorate;

[0055] During operation, when the cross plate 3 moves downward, the cross plate 3 drives the second telescopic rod 32 to move downward. When it moves to an appropriate position, it pushes the second piston 34 to move downward, compressing the gas inside the second sleeve 33, and then the gas inside the second sleeve 33 is ejected from the nozzle 36 through the second air pipe 35, so that the debris on the workbench 5 can be removed to avoid damage to the material.

[0056] Working principle:

[0057] During operation, when the raw material is placed in the lower mold 9, the first hydraulic rod 2 moves downward, the first hydraulic rod 2 drives the cross plate 3 to move downward, the cross plate 3 drives the support block 4 at the lower end to move downward, and the support block 4 drives the upper mold 6 to move downward until the upper mold 6 moves to the first groove 7. Because the first protrusion 1202 is connected to the circle 1208 for rotation, the circle 1208 will not rotate during the descent, and the material is pressed. At this time, the first hydraulic rod 2 moves upward. When the horizontal plate 3 is driven to move upward, the first support rod 1200 fixedly connected on the left side is driven to move upward inside the second circular hole 1207. The first support rod 1200 moves upward and drives multiple first rotating wheels 1201 to move upward. At this time, multiple first rotating wheels 1201 push the first protrusion 1202 to slide in turn. Under the action of the stopper 1212, the circle 1208 is rotated inside the annular groove 1209. When the circle 1208 rotates, due to the arc design of the second groove 1210, the moving wheel 1211 is displaced inward. At this time, the moving wheel 1211 drives the T-shaped block 1204 to move inside the first cavity 1203, and the T-shaped block 1204 drives the blade 1206 to move inward. When the first hydraulic rod 2 moves to the top, the moving wheel 1211 returns to the inside of the second groove 1210, and the first spring 1205 pushes the first protrusion 1202 to slide. The T-shaped block 1204 moves outward, the blade 1206 is retracted, and the edge of the material is cut in a circle to complete the edge deburring. After the deburring is completed, the second hydraulic rod 11 moves upward, driving the lower mold 9 to move upward at the same time to push the material out. In this way, the edge of the material is directly cut off, which reduces the workload of people and improves production efficiency. When the second support rod 40 moves downward, it moves against the second protrusion 15. Since the number of the second wheels 38 is greater than the second protrusion 15, the second wheels 38 can move the moving block 14 to the back. When the second support rod 40 moves upward, the moving block 14 can be moved to the front. The moving block 14 drives the first piston 41 to move forward inside the first sleeve 16. At this time, the internal pressure of the first sleeve 16 increases. When the second hydraulic rod 11 drives the lower mold 9 to move upward, the block 19 is separated from the vent 18. At this time, the gas will enter the vent hole 18, which ensures that the pressure at the bottom is the same as the external air pressure, making demoulding easier. When the second support rod 40 is moved out, the moving block 14 is reset due to the action of the second spring 37, so that demoulding is easier after the pressure is increased. When the cross plate 3 moves upward, the cross plate 3 drives the two sliders 21 to move inside the corresponding slide grooves 20. When the right slider 21 moves downward, the threaded rod 22 connected by the thread is driven to rotate. When the threaded rod 22 rotates, it drives the sweeping rod 23 fixedly connected to the bottom to move, so that the material can be unloaded, reducing the required manpower. When the cross plate 3 moves upward,The support block 4 is driven to move upward, and the second convex ball 27 is driven to move upward when the support block 4 moves upward. At this time, due to the extrusion of the first convex ball 24, the second convex ball 27 moves toward the inside of the third groove 25 and squeezes the third spring 26. When it is misaligned with the first convex ball 24, the second convex ball 27 moves outward under the tension of the third spring 26, so that the collision and vibration are generated, so that the demoulding effect of the top is better. When the sweeping rod 23 pushes the material to the carrying plate 30, due to the increase in gravity, at this time, the fourth spring 29 Under the action of the force, the carrying plate 30 slowly descends. At this time, when the cross plate 3 moves downward, when the rear side of the carrying plate 30 hits the two limit blocks 31, the two first telescopic rods 28 at the rear end contract, causing the entire carrying plate 30 to tilt and unload the materials. When the cross plate 3 moves upward, the carrying plate 30 is reset, which can reduce the damage to the materials during unloading. When the cross plate 3 moves downward, the cross plate 3 drives the second telescopic rod 32 to move downward. When it moves to the appropriate position, it moves downward against the second piston 34 to compress the gas inside the second sleeve 33, and then the gas inside the second sleeve 33 is ejected from the nozzle 36 through the second air pipe 35, so that the debris on the workbench 5 can be removed to avoid damage to the materials.
