Description

Technical Field

[0001] This invention relates to the field of hand mold processing technology, and more specifically, to an auxiliary demolding device in a hand mold production line based on waste recycling. Background Technology

[0002] Using recycled waste materials for hand mold production can effectively reduce production costs and improve environmental protection. In the hand mold processing and conveying process, the mold bar pushing and blocking mechanism is a core auxiliary demolding device for achieving precise positioning and transfer of the hand mold. Its main function is to block and limit the hand mold on the mold bar and push it to the designated position, providing the basic conditions for the subsequent robotic arm to grasp the hand mold. In the existing technology, most production lines use a pushing and blocking mechanism whose overall movement is completed by cylinder drive. That is, whether it is blocking and limiting the hand mold on the mold bar or pushing the hand mold to the target position, it is all achieved by the extension and retraction of the cylinder. In actual use, the cylinder controls the blocking shaft to extend and block the mold bar to stop the mold bar from moving. However, it cannot achieve precise stopping of the mold bar at different termination positions, which is not convenient for the robotic arm to grasp in the subsequent process and has a low applicability.

A slide block is slidably connected to the surface of the optical axis, and a sliding plate is fixedly installed on the top of the slide block. Both ends of the sliding assembly are fixedly equipped with blocking components. The blocking components include cylinders, which are fixedly installed on the bottom surfaces of the left and right ends of the sliding plate. The output end of the cylinder is fixedly sleeved with a lifting shaft.

[0005] As a preferred embodiment of the present invention, the transmission assembly includes a drive gear, which is fixedly sleeved on the output end of the motor. A driven gear is rotatably connected to the left end of the fixed base plate. A bevel gear is fixedly installed on the top end of the driven gear. The bevel gear consists of two bevel gears that mesh perpendicularly with each other. The two bevel gears are respectively fixedly sleeved on the top end of the driven gear and the middle part of the rotating shaft.

[0006] In a preferred embodiment of the present invention, the sliding plate and the chain are fixedly connected by a connecting assembly. The connecting assembly includes a connecting seat, which is fixedly installed on the top surface of the sliding plate. A connecting head is fixedly installed on the top end of the chain, and a stud is fixedly installed on the end of the connecting head near the connecting seat. A nut is engaged on the surface of the stud.

[0007] As a preferred embodiment of the present invention, the stud penetrates the connecting seat, and there are two nuts, which are respectively located on the front and rear sides of the connecting seat.

[0008] As a preferred embodiment of the present invention, the top end of the lifting shaft is provided with a positioning component, the positioning component includes a connecting hole, the connecting hole is opened at the top end of the lifting shaft, a rotating block is rotatably connected to the inner cavity of the connecting hole, a blocking block is fixedly installed at the top end of the rotating block, an extension plate is fixedly installed at the right end of the blocking block, an installation box is fixedly installed at the right end of the extension plate, a locking plate is slidably connected to the inner cavity of the installation box, and a spring is fixedly installed at the bottom end of the locking plate.

[0009] As a preferred embodiment of the present invention, the rear side of the top end of the locking plate is inclined, and the top end of the locking plate is located above the extension plate.

[0010] As a preferred embodiment of the present invention, the blocking block is provided with an adjustment component, the adjustment component includes a plug hole, the plug hole is opened at the front end of the blocking block, and locking holes are opened on both the front and rear sides of the lifting shaft, and locking pins are inserted into the plug hole and the locking hole.

[0011] As a preferred embodiment of the present invention, the top end of the locking pin is located above the blocking block, and the projection of the top surface of the locking pin in the vertical direction is located above the connecting seat.

[0012] As a preferred embodiment of the present invention, it further includes a push mold assembly, which includes a mold rod and a support bar. A slide rail is fixedly installed at the bottom end of the support bar, and a hand mold is provided at the top end of the mold rod. Rollers are rotatably connected to both the left and right ends of the mold rod, and the rollers are placed on the slide rail.

[0013] Compared with the prior art, the beneficial effects of the present invention are as follows: 1. This invention uses a motor to drive a rotating shaft and sprocket to rotate, which can move the top of the chain back and forth to a designated position. In other words, it can drive the lifting shaft on the sliding plate to move precisely to a designated position. At this time, when the cylinder drives the lifting shaft to extend, it can move the lifting shaft to the gripping position of the robot arm in the subsequent process according to the actual production needs. When the lifting shaft extends and contacts the mold bar, it can stop the cylinder precisely at different positions, thus improving the applicability of the device.

[0014] 2. When the mold rod moves and contacts the locking plate, the locking plate can be pressed down. Due to the presence of the spring, the mold rod will encounter resistance when pressing down on the locking plate, thereby reducing the impact force of the mold rod. When the mold rod contacts the blocking block, the mold rod and the locking plate are misaligned. At this time, the spring pushes the locking plate up under the action of elasticity and locks it on the other side of the mold rod, thereby achieving the positioning of the mold rod. When the mold rod moves to the blocking block, the impact on the blocking block is reduced, thereby improving the service life of the device. At the same time, it can also prevent the mold rod from moving in the opposite direction after contacting and impacting the blocking block, ensuring the positional accuracy of the mold rod.

[0017] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0018] like Figures 1 to 7 As shown, the present invention provides an auxiliary demolding device in a hand mold production line based on waste recycling, including a fixed base plate 1, a driving component 2 at the top of the fixed base plate 1, a sliding component 3 fixedly installed at the top of the driving component 2, and blocking components 5 fixedly installed on both the left and right sides of the sliding component 3. The drive assembly 2 includes a motor 21, which is fixedly mounted on the front end of the fixed base plate 1. The left and right ends of the fixed base plate 1 are rotatably connected to a rotating shaft 23, and the left and right ends of the rotating shaft 23 are fixedly mounted with sprockets 24. A transmission assembly 22 is connected between the output end of the motor 21 and the rotating shaft 23, and a chain 25 is connected to the surface of the sprocket 24. The sliding component 3 includes an optical axis 31, which is fixedly installed on the left and right sides of the fixed base plate 1. A slide block 32 is slidably connected to the surface of the optical axis 31, and a sliding plate 33 is fixedly installed on the top of the slide block 32. Both ends of the sliding component 3 are fixedly installed with blocking components 5. The blocking components 5 include cylinders 51. The cylinders 51 are fixedly installed on the bottom surfaces of the left and right ends of the sliding plate 33. The output end of the cylinders 51 is fixedly sleeved with lifting shafts 52.

[0019] By driving the rotating shaft 23 and sprocket 24 to rotate via the motor 21, the top of the chain 25 can be moved back and forth to a designated position. This allows the lifting shaft 52 on the sliding plate 33 to be precisely moved to a designated position. When the cylinder 51 drives the lifting shaft 52 to extend, it can move the lifting shaft 52 to the gripping position of the robot in the next process according to the actual production needs. When the lifting shaft 52 extends and contacts the mold bar 81, the cylinder 51 can be precisely stopped at different positions, thus improving the applicability of the device.

[0020] The transmission assembly 22 includes a drive gear 221, which is fixedly sleeved on the output end of the motor 21. A driven gear 222 is rotatably connected to the left end of the fixed base plate 1. A bevel gear 223 is fixedly installed on the top of the driven gear 222. The bevel gear 223 consists of two bevel gears 223 that mesh perpendicularly with each other. The two bevel gears 223 are respectively fixedly sleeved on the top of the driven gear 222 and the middle of the rotating shaft 23.

[0021] When the motor 21 is working, it drives the drive gear 221 to rotate. The meshing of the drive gear 221 and the driven gear 222 drives the lower bevel gear 223 to rotate, which in turn drives the upper bevel gear 223 to rotate, thereby driving the rotating shaft 23 to rotate.

[0022] The sliding plate 33 and the chain 25 are fixedly connected by a connecting component 4. The connecting component 4 includes a connecting seat 41, which is fixedly installed on the top surface of the sliding plate 33. A connector 42 is fixedly installed on the top end of the chain 25. A stud 43 is fixedly installed on the end of the connector 42 near the connecting seat 41. A nut 44 is engaged on the surface of the stud 43.

[0023] The connecting seat 41 is fixed to the sliding plate 33, and then the connecting head 42 is used to connect the connecting seat 41 and the chain 25, thus fixing the chain 25 and the sliding plate 33. When the chain 25 moves, it can drive the sliding plate 33 and the blocking component 5 installed on the sliding plate 33 to move.

[0024] Among them, the stud 43 passes through the connecting seat 41, and there are two nuts 44, which are located on the front and rear sides of the connecting seat 41 respectively.

[0025] By passing the stud 43 through the connector 41 and then locking the stud 43 onto the connector 41 with the nut 44, the connector 41 and the chain 25 can be fixed.

[0026] The lifting shaft 52 has a positioning component 6 at its top end. The positioning component 6 includes a connecting hole 61, which is located at the top end of the lifting shaft 52. A rotating block 62 is rotatably connected to the inner cavity of the connecting hole 61. A blocking block 63 is fixedly installed at the top end of the rotating block 62. An extension plate 64 is fixedly installed at the right end of the blocking block 63. An installation box 65 is fixedly installed at the right end of the extension plate 64. A locking plate 67 is slidably connected to the inner cavity of the installation box 65. A spring 66 is fixedly installed at the bottom end of the locking plate 67.

[0027] When the mold rod 81 moves and contacts the locking plate 67, the locking plate 67 can be pressed down. Due to the presence of the spring 66, the mold rod 81 will encounter resistance when pressing down the locking plate 67, thereby reducing the impact force of the mold rod 81. When the mold rod 81 contacts the blocking block 63, the mold rod 81 and the locking plate 67 are misaligned. At this time, the spring 66 pushes the locking plate 67 up under the action of elasticity, and jams it on the other side of the mold rod 81, thereby achieving the positioning of the mold rod 81. When the mold rod 81 moves to the blocking block 63, the impact on the blocking block 63 is reduced, thereby improving the service life of the device. At the same time, it can also prevent the mold rod 81 from moving in the opposite direction after contacting and impacting the blocking block 63, ensuring the positional accuracy of the mold rod 81.

[0028] The top rear side of the locking plate 67 is inclined, and the top of the locking plate 67 is located above the extension plate 64.

[0029] By setting the inclined surface of the locking plate 67, the locking plate 67 can be pressed down when the mold rod 81 contacts the inclined surface, so that the mold rod 81 can smoothly contact the blocking block 63.

[0030] The blocking block 63 is provided with an adjustment component 7, which includes a plug hole 71. The plug hole 71 is located at the front end of the blocking block 63. Locking holes 72 are provided on both the front and rear sides of the lifting shaft 52. Locking pins 73 are inserted into the plug hole 71 and the locking hole 72.

[0031] After the locking pin 73 is pulled out, the blocking block 63 can be rotated 180 degrees to adapt to the material feeding direction of the die rod 81, so that the die rod 81 can be smoothly stopped by the blocking block 63 from both the front and rear sides of the connecting component 4.

[0032] The top of the locking pin 73 is located above the blocking block 63, and the projection of the top surface of the locking pin 73 in the vertical direction is located above the connecting seat 41.

[0033] To prevent the connecting seat 41 from contacting the mold rod 81, ensure that the mold rod 81 only contacts the blocking block 63 when it moves.

[0034] It also includes a push mold assembly 8, which includes a mold rod 81 and a support bar 84. A slide rail 85 is fixedly installed at the bottom end of the support bar 84. A hand mold 82 is provided at the top end of the mold rod 81. Rollers 83 are rotatably connected to both the left and right ends of the mold rod 81 and are placed on the slide rail 85.

[0035] The support bar 84 and slide rail 85 support the mold rod 81 and position and guide the movement of the mold rod 81, so as to realize the overall forward and backward movement of the mold rod 81.

[0036] Working principle and usage process of this invention: The roller 83 rolls on the slide rail 85, enabling the mold bar 81 and the hand mold 82 to move horizontally back and forth. When it is necessary to stop the mold bar 81, the cylinder 51 drives the lifting shaft 52 to extend upward. At this time, the extension plate 64 is located on the bottom surface of the mold bar 81. When the mold bar 81 moves and contacts the locking plate 67, the locking plate 67 can be pressed down. Due to the presence of the spring 66, the mold bar 81 will be resisted when pressing down the locking plate 67, thereby reducing the impact force of the mold bar 81. When the mold bar 81 contacts the blocking block 63, the mold bar 81 and the locking plate 67 are misaligned. At this time, the spring 66 pushes the locking plate 67 upward under the action of elasticity, and jams it on the other side of the mold bar 81, thereby locking the mold bar 81. Subsequently, the rotating shaft 23 and sprocket 24 are driven to rotate by the motor 21, which can drive the top of the chain 25 to move back and forth, that is, drive the blocking block 63 on the sliding plate 33 to move precisely to the designated position, and push the mold bar 81 to move precisely to the required stop position. After the robotic arm performs the clamping and demolding, the cylinder 51 drives the lifting shaft 52 and the blocking block 63 to move down as a whole. At this time, the locking plate 67 moves down away from the mold rod 81, and the mold rod 81 loses its lock and resets.
