Description

Technical Field

[0001] The present invention relates to the technical field of magnetic tile molds, and in particular to a magnetic tile precision molding mold and a molding method. Background Art

[0002] As a key component of electromagnetic equipment, the molding quality and production efficiency of magnetic tiles have a crucial impact on the overall performance and manufacturing cost of electromagnetic equipment. However, in the manufacturing process of magnetic tiles, the existing molding molds and their supporting equipment have obvious technical bottlenecks in the feeding and demoulding links, which seriously restricts the development of the magnetic tile manufacturing industry.

[0003] First, in the manufacturing process of magnetic tiles, although the automatic feeding system has been introduced into the molding process, the coordination between the system and the mold clamping mechanism is insufficient, resulting in manual intervention to remove the feeding equipment after feeding to make room for mold clamping, and then start the mold clamping cylinder for mold clamping. This operation not only increases the labor intensity of workers and the complexity of the production process, but also significantly slows down production efficiency. In addition, there is a lack of necessary linkage design between the automatic feeding system and the ejection mechanism, resulting in the need for additional steps or reliance on other drive devices to assist the ejection operation after the magnetic tiles are formed. This not only further increases the complexity of the production process, but also increases the time consumption due to equipment start-up and shutdown, reduces the overall production efficiency, and also increases the difficulty of equipment maintenance and inspection.

When the lower mold is reset to the inside of the magnetic tile forming cavity, the arc surface at the bottom end of the push-pull starting rod is in active contact with the high end of the inclined surface of the second right-angled trapezoidal groove. When the upper mold base and the lower mold base are closed, the push-pull starting rod is adapted to slide with the lower end opening of the second right-angled trapezoidal groove, and at this time, the starting cross bar slides through the square groove setting.

[0017] The molding method using the above magnetic tile precision molding mold includes the following steps:

[0018] Step 1: In the initial state, the lower mold is pushed away from the magnetic tile forming cavity; when it is necessary to inject magnetic tile slurry into the magnetic tile forming cavity, first start the lifting cylinder, and the piston end thereof drives the lower mold base to move downward a certain distance, and at the same time, the bracket and the push-pull starting rod move downward accordingly; then, through the cooperation of the push-pull starting rod and the inclined surface of the second right-angle trapezoidal groove, the push-pull force block is pulled back, thereby driving the support rod, the L-shaped connecting rod and the starting cross bar to move; when the starting cross bar moves toward the direction of the first right-angle trapezoidal groove, through the cooperation of its arc surface and the inclined surface of the first right-angle trapezoidal groove, the ejection force rod is driven to move downward, and then the lower mold is pulled into the magnetic tile forming cavity through the ejection rod; when the starting cross bar moves to the high end along the inclined surface of the first right-angle trapezoidal groove, the lifting cylinder is closed, and at this time the push-pull starting rod is still located inside the second right-angle trapezoidal groove and keeps contact with the inclined surface;

[0019] Step 2: Then, feed the material into the magnetic tile forming cavity through the feeding part, and use the driving motor, the screw and the moving beam to realize feeding into multiple magnetic tile forming cavities. When the magnetic tile slurry is fully added into the magnetic tile forming cavity, the mold closing operation is performed;

[0020] Step 3: When closing the mold, start the lifting cylinder again, and its piston end drives the upper mold base and the upper mold to move downward. At the same time, the bracket and the push-pull start rod move downward accordingly. When the push-pull start rod moves downward, the arc surface at its bottom end cooperates with the inclined surface of the second right-angle trapezoidal groove to pull the push-pull force block backward again, thereby driving the support rod, the L-shaped connecting rod and the start cross bar to move; at this time, the start cross bar slides inside the square groove, and when the push-pull start rod moves out from the bottom end of the second right-angle trapezoidal groove, the moving cross beam is dislocated with the lower mold base to prepare for closing the mold;

[0021] Step 4: Then, the upper mold base and the upper mold are driven downward by the lifting cylinder. At this time, the push-pull start rod slides downward along the bottom end of the second right-angle trapezoidal groove, and the start cross bar continues to slide inside the square groove until the upper mold and the lower mold are completely molded, and then the lifting cylinder is closed;

[0022] Step 5: When the mold needs to be opened, the upper mold base and the upper mold are driven to move upward by the lifting cylinder. At the same time, the bracket and the push-pull starting rod rise accordingly. When the push-pull starting rod rises and enters the second right-angled trapezoidal groove and moves from the lower end to the higher end of the second right-angled trapezoidal groove inclined surface, under the action of the rebound force of the second reset spring, the push-pull force block drives the support rod to move toward the lower mold base and reset. During this process, the starting cross bar moves with the support rod. After the starting cross bar moves out of the square groove, it continues to move with the support rod; due to the cooperation between the first right-angled trapezoidal groove inclined surface and the first reset spring, the ejection force rod drives the ejection rod to move upward under the action of the rebound force of the first spring, thereby pushing the lower mold and the magnetic tile formed at its top to move upward; when the starting cross bar moves to the lower end of the first right-angled trapezoidal groove inclined surface, the lifting cylinder is closed. At this time, the lower mold is pushed out of the magnetic tile forming cavity, which is convenient for removing the product, and this cycle is repeated.

[0023] Beneficial effects of the present invention:

[0024] 1. The present invention realizes the automated coordination of feeding, mold closing and ejection operations through precise mechanical linkage design. After the feeding is completed, the feeding unit can be automatically withdrawn during the mold closing process without manual intervention, which significantly reduces the labor intensity of workers and the complexity of the production process, thereby greatly improving production efficiency. At the same time, the linkage design between the ejection unit and the feeding unit also avoids additional operating steps or reliance on other drive devices for assistance, which not only further reduces the complexity of the production process, but also reduces the time consumed by the start and stop of the equipment, thereby further improving the overall production efficiency of the magnetic tile.

[0025] 2. The connection between the feeding, mold closing and ejection operations in the present invention is closer, reducing the risk of failure caused by increased operations. In addition, since manual operations and additional drive devices are reduced, the difficulty of equipment maintenance and inspection is also reduced accordingly, which helps to extend the service life of the equipment and reduce downtime.

[0041] Example 1

[0042] Reference Figure 1-7 , which is the first embodiment of the present invention, provides a magnetic tile precision molding mold, which mainly includes:

[0043] The main unit 100, such as Figure 1-2 The main unit 100 includes a base 101, a top plate 102 located above the base 101, a lifting cylinder 103 fixedly connected to the top of the top plate 102 by bolts, an upper die seat 104 fixedly connected to the bottom piston end of the lifting cylinder 103, an upper die 105 fixedly connected to the bottom of the upper die seat 104 in a linear array, and a lower die seat 106 located directly below the upper die seat 104.

Support columns are fixedly connected to the four corners of the top of the base 101 by bolts, and the tops of the four support columns are fixedly connected to the four corners of the top plate 102 respectively. A magnetic tile forming cavity 107 is provided at the top of the lower die seat 106 corresponding to the upper die 105. The magnetic tile forming cavity 107 is sealed and adapted to slide with a lower die 108 adapted to the upper die 105. When the mold is closed, the upper mold base 104 is driven downward by the lifting cylinder 103, and the upper mold base 104 drives the upper mold 105 to move downward to close the mold.

[0044] The feeding unit 300, such as Figure 2The feeding unit 300 is located at the rear side of the lower mold base 106 and is connected to the base 101 , the ejection unit 200 , and the top of the upper mold base 104 . The feeding unit 300 is used to add magnetic tile forming slurry into the magnetic tile forming cavity 107 .

[0045] Specifically, Figure 4 The feeding unit 300 includes a slide rail 301 fixedly connected to the top of the base 101, a slider 302 adapted to slide with the top of the slide rail 301, a support rod 303 fixedly connected to the top of the slider 302, a moving component 304 fixedly connected to the top of the support rod 303, a feeding part 305 fixedly connected to the bottom of the moving component 304, and a push-pull avoidance component 306 fixedly connected to the side of the support rod 303 away from the lower mold base 106, and the push-pull avoidance component 306 is connected to the base 101 and the upper mold base 104.

[0046] like Figure 4 The moving assembly 304 includes a frame 304-1 fixedly connected to the top of the support rod 303, the frame 304-1 is a rectangular structure connected on the left and right sides, a screw is rotatably installed inside the frame 304-1 through a bearing, one end of the frame 304-1 is fixedly connected to a drive motor 304-2 through a bolt, the output end of the drive motor 304-2 is fixedly connected to one end of the screw, a moving beam 304-3 is threadedly connected to the screw, the moving beam 304-3 is adapted to slide with the inside of the frame 304-1, the purpose of such connection is to limit and guide the moving beam 304-3, so that when the screw rotates, the moving beam 304-3 can move along the screw, so that the feeding part 305 moves for feeding, the feeding part 305 is fixedly connected to the bottom of the moving beam 304-3, the feeding part 305 usually includes a feeding box, a feeding pump, a feeding pipe, a feeding pipe, etc. (Not all are shown in the figure), the feeding box is used to store magnetic tile slurry and can be placed on the base 101 or the nearby ground. The feeding pipe is connected to the deep inside of the feeding box, the feeding pump is installed on the feeding pipe, and the top of the feeding pipe is fixedly connected to the feeding pipe through a hose. In addition, the feeding pipe is fixedly connected to the bottom of the movable crossbeam 304-3, and a filling valve can be installed on the feeding pipe to control the feeding amount. Therefore, when adding material, start the feeding pump, and use the feeding pump to transport the magnetic tile slurry in the feeding box to the feeding pipe, and then enter the feeding pipe through the hose, and then fall into the magnetic tile forming cavity 107 through the feeding pipe. When the slurry in the magnetic tile forming cavity 107 reaches the setting amount of the filling valve, close the feeding pipe and the feeding pump, and then start the drive motor 304-2. The drive motor 304-2 drives the screw to rotate, so that the movable crossbeam 304-3 drives the feeding pipe in the feeding part 305 to move to the top of the next magnetic tile forming cavity 107 for feeding.

[0047] Specifically, Figure 4-5The push-pull avoidance component 306 includes a push-pull force block 306-1 fixedly connected to the rear side of the support rod 303 by bolts, a second slide bar 306-2 fixedly connected to the end of the push-pull force block 306-1 away from the support rod 303, a fixed plate 306-3 slidably connected to the second slide bar 306-2, a push-pull starting component 306-4 connected to the push-pull force block 306-1, and a limit plate 306-5 fixedly connected to the end of the second slide bar 306-2 away from the support rod 303 by bolts, the bottom of the fixed plate 306-3 is fixedly connected to the upper surface of the base 101, and the limit plate 306 -5 is fixedly connected with the fixed plate 306-3 with a second return spring 306-6, and the second return spring 306-6 is movably sleeved on the outside of the second slide bar 306-2. By setting the second return spring 306-6, the feeding part 305 can be gradually reset during the mold opening process, and the push-pull starting component 306-4 is fixedly connected with the upper mold base 104; the upper and lower sides of the push-pull force block 306-1 are provided with second right-angled trapezoidal grooves 306-7 that are interconnected, and the side of the second right-angled trapezoidal groove 306-7 away from the support rod 303 is an inclined surface, and the lower end of the inclined surface is arranged close to the support rod 303.

[0048] like Figure 5 The push-pull starting assembly 306-4 includes a bracket 306-41 fixedly connected to the top of the upper mold base 104, the bracket 306-41 slides through the top plate 102, and a push-pull starting rod 306-42 is fixedly connected to the inner top wall of the bracket 306-41. The push-pull starting rod 306-42 slides through the top plate 102, and the bottom end of the push-pull starting rod 306-42 is set to an arc shape. When the lower mold 108 is reset to the inside of the magnetic tile forming cavity 107, the arc surface of the bottom end of the push-pull starting rod 306-42 is in active contact with the high end of the inclined surface of the second right-angled trapezoidal groove 306-7. When the upper mold base 104 and the lower mold base 106 are molded together, the push-pull starting rod 306-42 is adapted to slide with the lower end opening of the second right-angled trapezoidal groove 306-7, and at this time, the starting cross bar 202-1 slides through the square groove 201-7.

[0049] In summary, when in use, in the initial state, the lower mold 108 is pushed away from the magnetic tile forming cavity 107 (such as Figure 5); when it is necessary to inject magnetic tile slurry into the magnetic tile forming cavity 107, first start the lifting cylinder 103, and the piston end thereof drives the lower mold base 106 to move downward a certain distance, and at the same time, the bracket 306-41 and the push-pull starting rod 306-42 move downward accordingly; then, by using the push-pull starting rod 306-42 in conjunction with the inclined surface of the second right-angle trapezoidal groove 306-7, the push-pull force block 306-1 is pulled back, thereby driving the support rod 303 to move, and when the feeding tube in the feeding part 305 is located directly above the middle of the magnetic tile forming cavity 107, the lifting cylinder 103 is closed, and at this time the push-pull starting rod 306-42 is still located inside the second right-angle trapezoidal groove 306-7 and maintains contact with the inclined surface (such as Figure 6 ), so that when the push-pull start rod 306-42 moves down again, the push-pull start rod 306-42 can also be used in conjunction with the inclined surface of the second right-angle trapezoidal groove 306-7 to pull the push-pull force block 306-1 to continue to retreat. Next, the material is added to the magnetic tile forming cavity 107 through the feeding part 305, and the driving motor 304-2, the screw rod and the moving crossbeam 304-3 are used in conjunction to achieve the feeding of multiple magnetic tile forming cavities 107. When the magnetic tile slurry is fully added to the magnetic tile forming cavity 107, the mold closing operation is performed. When closing the mold, start the lifting cylinder 103 again, and its piston end drives the upper mold base 104 and the upper mold 105 to move downward. At the same time, the bracket 306-41 and the push-pull start rod 306-42 move downward accordingly. When the push-pull start rod 306-42 moves downward, the push-pull force block 306-1 is pulled back again through the cooperation of the arc surface at its bottom end and the inclined surface of the second right-angle trapezoidal groove 306-7, thereby driving the support rod 303 and the L-shaped connecting rod 202-3 to move. When the push-pull start rod 306-42 moves out from the bottom end of the second right-angle trapezoidal groove 306-7, the moving beam 304-3 is misaligned with the lower mold base 106 to prepare for closing the mold. Then, the upper mold base 104 and the upper mold 105 continue to move downward through the lifting cylinder 103. At this time, the push-pull start rod 306-42 slides downward along the bottom end of the second right-angle trapezoidal groove 306-7 until the upper mold 105 and the lower mold 108 are completely molded (such as Figure 7 ), close the lifting cylinder 103. When the mold needs to be opened, the lifting cylinder 103 drives the upper mold base 104 and the upper mold 105 to move upward, and at the same time, the bracket 306-41 and the push-pull start rod 306-42 rise accordingly. When the push-pull start rod 306-42 rises and enters the second right-angle trapezoidal groove 306-7, and moves from the lower end to the higher end of the inclined surface of the second right-angle trapezoidal groove 306-7, under the action of the rebound force of the second reset spring 306-6, the push-pull force block 306-1 drives the support rod 303 to move toward the lower mold base 106 and reset (such as Figure 5The overall operation is simple, and the feeding unit 300 can be automatically removed during the mold closing process without manual intervention, which can significantly reduce the labor intensity of workers and the complexity of the production process, thereby greatly improving production efficiency.

The bottom end of the ejection unit 200 is fixedly connected to the top of the base 101, and the top end is slidably inserted into the magnetic tile forming cavity 107 and fixedly connected to the bottom of the lower mold 108.

[0052] Specifically, Figure 8 The ejection unit 200 includes a plurality of telescopic components 201, each of which corresponds to the lower mold 108 one by one. The bottom end of the telescopic component 201 is fixedly connected to the top of the base 101. The top end of the telescopic component 201 is slidably inserted into the magnetic tile forming cavity 107 and is fixedly connected to the bottom of the lower mold 108. An ejection start component 202 is provided on the front side of the telescopic component 201, and the ejection start component 202 is fixedly connected to the feeding unit 300.

[0053] Furthermore, if Fig. 9The telescopic assembly 201 includes an ejector rod 201-1 fixedly connected to the bottom of the lower mold 108, the bottom end of the ejector rod 201-1 slides through the magnetic tile molding cavity 107 and is fixedly connected to an ejector force rod 201-2, a groove 201-3 is provided at the bottom of the ejector force rod 201-2, a first slide bar 201-4 is adapted to slide inside the groove 201-3, the bottom end of the first slide bar 201-4 is fixedly connected to a mounting plate, the bottom of the mounting plate is fixedly connected to the upper surface of the base 101, a first return spring 201-5 is fixedly connected between the top of the mounting plate and the bottom end of the ejector force rod 201-2, and the first return spring 201-5 is movably sleeved on the outside of the first slide bar 201-4; the ejector force rod 201- A first right-angled trapezoidal groove 201-6 is provided on the side away from the feeding unit 300, and the inner bottom surface of the first right-angled trapezoidal groove 201-6 is an inclined surface, and the lower end of the inclined surface is located at the notch of the first right-angled trapezoidal groove 201-6. A square groove 201-7 connected to the first right-angled trapezoidal groove 201-6 is provided on the side of the ejection force-bearing rod 201-2 facing the feeding unit 300, and the inner bottom wall of the square groove 201-7 is flushly connected with the high end of the bottom inclined surface of the first right-angled trapezoidal groove 201-6, and the connection is set to be in an arc shape. This design facilitates the ejection rod 201-1 to enter the square groove 201-7 from the inclined surface of the first right-angled trapezoidal groove 201-6, and the inner top wall of the square groove 201-7 is flush with the inner top wall of the first right-angled trapezoidal groove 201-6.

[0054] Furthermore, Figure 8 The ejection start assembly 202 includes a plurality of start cross bars 202-1, and the plurality of start cross bars 202-1 are located on the side of the ejection force rod 201-2 away from the feeding unit 300, and correspond to the first right-angle trapezoidal groove 201-6 one by one, and the ends of the plurality of start cross bars 202-1 away from the ejection force rod 201-2 are fixedly connected to the same synchronization rod 202-2, and both ends of the synchronization rod 202-2 are fixedly connected to L-shaped connecting rods 202-3, and the end of the L-shaped connecting rod 202-3 away from the synchronization rod 202-2 is fixedly connected to the support rod 303, so that the L-shaped connecting rod 202-3 can move following the support rod 303.

[0055] One end of the starting cross bar 202-1 facing the first right-angle trapezoidal groove 201-6 is set as an arc surface. When the lower mold 108 is ejected from the magnetic tile forming cavity 107, the arc surface on the starting cross bar 202-1 is in active contact with the lower end of the inclined surface of the first right-angle trapezoidal groove 201-6. When the lower mold 108 is reset to the inside of the magnetic tile forming cavity 107, the starting cross bar 202-1 corresponds to the square groove 201-7. When the feeding unit 300 retreats to make room for the lower mold base 106 to move downward, the starting cross bar 202-1 is adapted to slide with the square groove 201-7.

[0056] The remaining structures are the same as those of Example 1.

[0057] When in use, the L-shaped connecting rod 202-3 moves with the support rod 303, thereby realizing the linkage between the ejection unit 200 and the feeding unit 300, that is, when the feeding unit 200 is reset, the ejection unit 200 can automatically eject the lower mold 108 from the magnetic tile forming cavity 107, making it convenient to remove the product, thereby further reducing the complexity of the production process and reducing the time consumed by equipment start-up and shutdown, thereby further improving the overall production efficiency of the magnetic tiles.

[0058] The molding method using the above magnetic tile precision molding mold is as follows: in the initial state, the lower mold 108 is pushed away from the magnetic tile molding cavity 107; when it is necessary to inject magnetic tile slurry into the magnetic tile molding cavity 107, the lifting cylinder 103 is first started, and the piston end thereof drives the lower mold base 106 to move downward a certain distance, and at the same time, the bracket 306-41 and the push-pull start rod 306-42 move downward accordingly; then, through the cooperation of the push-pull start rod 306-42 and the inclined surface of the second right-angle trapezoidal groove 306-7 When the push-pull force block 306-1 is used, the push-pull force block 306-1 is pulled back, thereby driving the support rod 303, the L-shaped connecting rod 202-3 and the starting cross bar 202-1 to move; when the starting cross bar 202-1 moves toward the first right-angle trapezoidal groove 201-6, the arc surface thereof cooperates with the inclined surface of the first right-angle trapezoidal groove 201-6 to drive the ejection force rod 201-2 to move downward, and then the lower mold 108 is pulled into the interior of the magnetic tile forming cavity 107 (such as the ejection rod 201-1) through the ejection rod 201-1. Figure 6 ); When the start cross bar 202-1 moves to the high end along the inclined surface of the first right-angle trapezoidal groove 201-6, the lifting cylinder 103 is closed, and at this time, the push-pull start rod 306-42 is still located inside the second right-angle trapezoidal groove 306-7 and keeps contact with the inclined surface. Next, the material is added to the magnetic tile forming cavity 107 through the feeding part 305, and the driving motor 304-2, the screw rod and the moving cross beam 304-3 are used in coordination to realize the feeding of multiple magnetic tile forming cavities 107. When the magnetic tile slurry is fully added to the magnetic tile forming cavity 107, the mold closing operation is performed. When the mold is closed, the lifting cylinder 103 is started again, and its piston end drives the upper mold base 104 and the upper mold 105 to move downward. At the same time, the bracket 306-41 and the push-pull starting rod 306-42 move downward accordingly. When the push-pull starting rod 306-42 moves downward, the arc surface at its bottom end cooperates with the inclined surface of the second right-angle trapezoidal groove 306-7 to pull the push-pull force block 306-1 back again, thereby driving the support rod 303, the L-shaped connecting rod 202-3 and the starting cross bar 202-1 to move; at this time, the starting cross bar 202-1 slides inside the square groove 201-7 (such as Figure 7), when the push-pull start rod 306-42 moves out from the bottom of the second right-angle trapezoidal groove 306-7, the moving crossbeam 304-3 is misaligned with the lower mold base 106, preparing for mold closing. Then, the upper mold base 104 and the upper mold 105 are driven downward by the lifting cylinder 103. At this time, the push-pull start rod 306-42 slides downward along the bottom of the second right-angle trapezoidal groove 306-7, and the start crossbar 202-1 continues to slide inside the square groove 201-7 until the upper mold 105 and the lower mold 108 are completely molded, and the lifting cylinder 103 is closed. When the mold needs to be opened, the upper mold base 104 and the upper mold 105 are driven to move upward by the lifting cylinder 103. At the same time, the bracket 306-41 and the push-pull starting rod 306-42 rise accordingly. When the push-pull starting rod 306-42 rises and enters the second right-angled trapezoidal groove 306-7 and moves from the lower end to the higher end of the inclined surface of the second right-angled trapezoidal groove 306-7, under the action of the rebound force of the second reset spring 306-6, the push-pull force block 306-1 drives the support rod 303 to move toward the lower mold base 106 and reset. In this process, the starting cross bar 202-1 moves with the support rod 303. When the starting cross bar 202-1 is After the rod 202-1 moves out from the inside of the square groove 201-7, it continues to move with the support rod 303; due to the cooperation between the inclined surface of the first right-angle trapezoidal groove 201-6 and the first return spring 201-5, the ejection force rod 201-2 drives the ejection rod 201-1 to move upward under the action of the rebound force of the first spring 201-5, thereby pushing the lower mold 108 and the magnetic tile formed at the top thereof to move upward; when the starting cross bar 202-1 moves to the lower end of the inclined surface of the first right-angle trapezoidal groove 201-6, the lifting cylinder 103 is closed. At this time, the lower mold 108 is pushed out of the magnetic tile forming cavity 107, making it convenient to remove the product, and this cycle is repeated.

[0059] It is worth noting that the entire device is controlled by a controller. Since the controller is a commonly used device and belongs to the existing mature technology, its electrical connection relationship and specific circuit structure will not be described in detail here.
