Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of magnetic tile mold, and particularly to a magnetic tile precision forming mold and a forming method. BACKGROUND

[0002] As a key component in electromagnetic equipment, the forming quality and production efficiency of the magnetic tile have a crucial influence on the overall performance and manufacturing cost of the electromagnetic equipment. However, in the manufacturing process of the magnetic tile, the existing forming mold and its supporting equipment have obvious technical bottlenecks in the feeding and demolding links, which seriously restrict the development of the magnetic tile manufacturing industry.

[0003] Firstly, in the manufacturing process of the magnetic tile, although an automatic feeding system has been introduced into the forming process, the cooperation between the system and the mold closing mechanism is insufficient, which causes the feeding to still need manual intervention to remove the feeding equipment to make room for mold closing, and then to start the mold closing cylinder for mold closing. This operation not only increases the labor intensity of the workers and the complexity of the production process, but also significantly slows down the production efficiency. In addition, the automatic feeding system lacks necessary linkage design with the ejection mechanism, which causes the ejection operation to need additional steps or rely on other driving devices for assistance after the magnetic tile is formed. This not only further increases the complexity of the production process, but also increases the time consumption due to the start and stop of the equipment, reduces the overall production efficiency, and also increases the difficulty of equipment maintenance and inspection.

[0017] The forming method using the above-mentioned magnetic tile precision forming die comprises the following steps:

[0018] Step one: in the initial state, the lower die is lifted away from the magnetic tile forming cavity; when it is needed to inject magnetic tile slurry into the magnetic tile forming cavity, first start the lifting cylinder, drive the lower die holder to move downward by a certain distance through the piston end, at the same time, the bracket and the push-pull starting rod move downward; then, through the cooperation of the push-pull starting rod and the inclined surface of the second right-angled trapezoidal groove, pull the push-pull force block to retreat, thereby driving the supporting rod, the L-shaped connecting rod and the starting cross rod to move; when the starting cross rod moves towards the first right-angled trapezoidal groove, through the cooperation of the circular arc surface and the inclined surface of the first right-angled trapezoidal groove, drive the ejection force rod to move downward, and then pull the lower die into the magnetic tile forming cavity through the ejection rod; when the starting cross rod moves along the inclined surface of the first right-angled trapezoidal groove to the high end, turn off the lifting cylinder, and at this time, the push-pull starting rod is still located in the second right-angled trapezoidal groove and keeps contact with the inclined surface;

[0019] Step two: then, add material into the magnetic tile forming cavity through the feeding part, realize the feeding into multiple magnetic tile forming cavities through the cooperation of the driving motor, the screw rod and the moving cross beam, and when all the magnetic tile forming cavities are filled with magnetic tile slurry, perform the closing operation;

[0020] Step three: when closing, start the lifting cylinder again, drive the upper die holder and the upper die to move downward through the piston end, at the same time, the bracket and the push-pull starting rod move downward, when the push-pull starting rod moves downward, through the cooperation of the bottom end circular arc surface and the inclined surface of the second right-angled trapezoidal groove, pull the push-pull force block to retreat again, thereby driving the supporting rod, the L-shaped connecting rod and the starting cross rod to move; at this time, the starting cross rod slides in the square groove, when the push-pull starting rod moves out of the bottom end of the second right-angled trapezoidal groove, the moving cross beam is dislocated with the lower die holder, preparing for the closing operation;

[0021] Step four: then, continue to drive the upper die holder and the upper die to move downward through the lifting cylinder, at this time, the push-pull starting rod slides downward along the bottom end of the second right-angled trapezoidal groove, while the starting cross rod continues to slide in the square groove, until the upper die and the lower die are completely closed, turn off the lifting cylinder.

[0022] Step five: when the mold needs to be opened, the upper mold base and the upper mold are moved upward by the lifting cylinder, at the same time, the support and the push-pull starting rod are lifted, when the push-pull starting rod is lifted into the second right trapezoidal groove and moves from the low end to the high end of the second right trapezoidal groove, the push-pull force block drives the support rod to move to the lower mold base under the rebound force of the second reset spring, in this process, the starting horizontal rod moves with the support rod, and when the starting horizontal rod moves out of the square groove, it continues to move with the support rod; due to the cooperation of the first right trapezoidal groove slope and the first reset spring, the ejection force rod drives the ejection rod to move upward under the rebound force of the first reset spring, thereby pushing the lower mold and the magnetic tile formed at the top of the lower mold upward; when the starting horizontal rod moves to the low end of the first right trapezoidal groove slope, the lifting cylinder is turned off, at this time, the lower mold is pushed out of the magnetic tile forming cavity, which facilitates the removal of the product, and the cycle is repeated.

[0023] The beneficial effects of the present application are:

[0024] The present application realizes the automation of the feeding, clamping and ejection operations through precise mechanical linkage design. After the feeding is completed, the feeding unit can be automatically removed during the clamping process without manual intervention, significantly reducing the labor intensity of workers and the complexity of the production process, thereby greatly improving the production efficiency. At the same time, the linkage design between the ejection unit and the feeding unit also avoids additional operation steps or reliance on other driving devices, 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] The connection between feeding, clamping and ejection operations in the present application is more closely linked, reducing the risk of failure that may be caused by increased operations. In addition, due to the reduction of manual operation and additional driving devices, the difficulty of equipment maintenance and inspection is also reduced, which helps to prolong the service life of the equipment and reduce downtime.

When the mold is closed, the upper die seat 104 is driven to move downward by the lifting cylinder 103, and the upper die 105 is driven to move downward by the upper die seat 104.

[0043] The feeding unit 300, such as Figure 2The feeding unit 300 is located at the rear side of the lower die seat 106 and is connected with the base 101, the ejection unit 200 and the top of the upper die seat 104, and is used for adding the magnetic tile forming slurry into the magnetic tile forming cavity 107.

[0052] Further, as Figure 8 The ejection starting assembly 202 comprises a plurality of starting cross rods 202-1, the starting cross rods 202-1 are located on the side of the ejection force rod 201-2 away from the feeding unit 300, and are in one-to-one correspondence with the first right trapezoidal grooves 201-6, respectively, one end of the starting cross rods 202-1 away from the ejection force rod 201-2 is fixedly connected with a same synchronous rod 202-2, both ends of the synchronous rod 202-2 are fixedly connected with L-shaped connecting rods 202-3, and one end of the L-shaped connecting rods 202-3 away from the synchronous rod 202-2 is fixedly connected with the supporting rod 303, so that the L-shaped connecting rods 202-3 can move with the supporting rod 303.

[0053] The end of the starting cross rod 202-1 towards the first right trapezoidal groove 201-6 is designed in a circular arc surface, when the lower mold 108 is ejected from the magnetic tile forming cavity 107, the circular arc surface on the starting cross rod 202-1 is in movable contact with the low end of the slope of the first right trapezoidal groove 201-6, when the lower mold 108 is reset to the inside of the magnetic tile forming cavity 107, the starting cross rod 202-1 corresponds to the square groove 201-7, when the feeding unit 300 retreats to make the lower mold seat 106 move downward to form a space, the starting cross rod 202-1 is slidably connected with the square groove 201-7.

[0054] The remaining structure is the same as that in Example 1.

[0055] In use, the L-shaped connecting rod 202-3 moves along with the support rod 303, thereby enabling 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. This further reduces the complexity of the production process and the time consumed by equipment start-up and shutdown, thereby further improving the overall production efficiency of magnetic tiles.

[0056] The forming method using the above-mentioned precision forming mold for magnetic tiles is as follows: In the initial state, the lower mold 108 is pushed away from the magnetic tile forming cavity 107; when it is necessary to inject magnetic tile slurry into the magnetic tile forming cavity 107, the lifting cylinder 103 is first activated, and its piston end drives the lower mold base 106 to move downward a certain distance. At the same time, the bracket 306-41 and the push-pull starting rod 306-42 move downward accordingly; subsequently, the push-pull starting rod 306-42 cooperates with the inclined surface of the second right-angle trapezoidal groove 306-7. When used, pulling the push-pull force block 306-1 backward causes the support rod 303, L-shaped connecting rod 202-3, and starting crossbar 202-1 to move. As the starting crossbar 202-1 moves towards the first right-angled trapezoidal groove 201-6, its arc surface engages with the inclined surface of the first right-angled trapezoidal groove 201-6, causing the ejector force rod 201-2 to move downward. This, in turn, pulls the lower mold 108 into the magnetic tile forming cavity 107 via the ejector rod 201-1 (e.g., ...). Figure 6 When the starting crossbar 202-1 moves to the high end along the inclined surface of the first right-angled trapezoidal groove 201-6, the lifting cylinder 103 is closed. At this time, the push-pull starting rod 306-42 is still located inside the second right-angled trapezoidal groove 306-7 and remains in contact with the inclined surface. Next, material is added to the magnetic tile forming cavity 107 through the feeding part 305. By using the cooperation of the drive motor 304-2, the screw, and the moving crossbeam 304-3, material is added to multiple magnetic tile forming cavities 107. After all the magnetic tile slurry has been added to the magnetic tile forming cavity 107, the mold closing operation is performed. When the mold is closed, the lifting cylinder 103 is activated 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. When the push-pull starting rod 306-42 moves downward, through the cooperation of its bottom arc surface and the inclined surface of the second right-angle trapezoidal groove 306-7, it pulls the push-pull force block 306-1 backward again, thereby driving the support rod 303, the L-shaped connecting rod 202-3 and the starting crossbar 202-1 to move. At this time, the starting crossbar 202-1 slides inside the square groove 201-7 (e.g., Figure 7), when the push-pull starting rod 306-42 is moved out from the bottom end of the second right trapezoidal groove 306-7, the moving crossbeam 304-3 is misaligned with the lower die seat 106, preparing for the mold closing. Then, the upper die seat 104 and the upper die 105 continue to be moved downward by the lifting cylinder 103, at this time, the push-pull starting rod 306-42 slides downward along the bottom end of the second right trapezoidal groove 306-7, and the starting crossbar 202-1 continues to slide inside the square groove 201-7, until the upper die 105 is completely closed with the lower die 108, the lifting cylinder 103 is closed. When the mold needs to be opened, the upper die seat 104 and the upper die 105 are moved upward by the lifting cylinder 103, at the same time, the support 306-41 and the push-pull starting rod 306-42 are raised, when the push-pull starting rod 306-42 rises into the second right trapezoidal groove 306-7 and moves from the low end to the high end of the second right trapezoidal groove 306-7, under the action of the rebound force of the second return spring 306-6, the push-pull force block 306-1 drives the support rod 303 to move back to the direction of the lower die seat 106, in this process, the starting crossbar 202-1 moves with the support rod 303, and continues to move with the support rod 303 when the starting crossbar 202-1 moves out of the square groove 201-7; due to the cooperation of the slope of the first right 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 return spring 201-5, and then pushes the lower die 108 and the magnetic tile formed at the top of the lower die 108 upward; when the starting crossbar 202-1 moves to the low end of the slope of the first right trapezoidal groove 201-6, the lifting cylinder 103 is closed, at this time, the lower die 108 is pushed out of the magnetic tile forming cavity 107, facilitating the removal of the product, and the cycle is repeated.
