Description

Technical Field

[0001] This invention relates to the field of magnetic tile manufacturing technology, and in particular to a universal mold for ferrite magnetic tiles. Background Technology

[0002] In current ferrite tile production, the mold frame and mold are designed as a rigid, one-to-one pair: each new mold set requires a custom-made mold frame, and the two are rigidly connected by a fixed structure, making them inseparable. This approach has significant drawbacks:

[0003] 1. Low changeover efficiency: When changing to different specifications of magnetic tile molds, the mold frame and mold assembly need to be completely disassembled, and a single changeover takes as long as 1.5-2 hours, which seriously restricts the flexibility of the production line;

[0004] 2. High cost: Each mold is equipped with an independent mold frame, and the material cost accounts for more than 35% of the total cost of the mold. Moreover, the idle mold frame occupies storage space for a long time.

[0005] 3. Complex debugging: When assembling the new mold frame with the press, the positioning accuracy needs to be recalibrated. A single debugging session takes an average of 1-3 hours, and repetitive work accounts for more than 30%. Summary of the Invention

[0006] To address the above problems, the present invention provides the following solution:

[0007] A universal mold frame for ferrite magnetic tiles includes a floating assembly and a support assembly. The support assembly includes a first support plate and a second support plate. The first support plate has multiple floating connection holes symmetrically arranged, and multiple fixing holes for fixing to a press are arranged along its edge. The second support plate is located at the center of the top surface of the first support plate, and the second support plate and the first support plate are fixedly connected by support connecting bolts. The floating assembly includes a floating plate, a floating connecting plate, a floating guide shaft, and a floating guide sleeve. The center of the floating plate has a floating groove corresponding to the outline of the second support plate, and the floating plate is sleeved on the outside of the second support plate. A floating guide shaft is provided at the bottom of the floating plate corresponding to the floating connection hole, and a floating guide sleeve is provided in the floating connection hole. The lower end of the floating guide shaft passes through the floating guide sleeve and is fixedly connected to the floating connecting plate. The bottom of the floating connecting plate is fixedly connected to the lower cylinder of the press.

[0008] Furthermore, the first support plate has six floating connection holes, which are symmetrically arranged about the long axis of the first support plate.

[0009] Furthermore, in the floating connection holes, the top of the floating guide sleeves located at the four corners extends outward with a guide shaft protective sleeve.

[0010] Furthermore, the top of the floating guide shaft in the floating connection hole at each of the four corners is screwed to the second support plate, and square nuts are provided in the second support plate corresponding to the floating guide shaft at each of the four corners. The top of the floating guide shaft at each of the four corners is screwed to the square nuts.

[0011] Furthermore, a floating guide shaft bolt is fixedly installed at the bottom center of the floating guide shaft, and a floating connection hole is opened on the floating connecting plate corresponding to the floating guide shaft bolt. After the floating guide shaft bolt passes through the floating connection hole, a nut is screwed in to fix the floating guide shaft to the floating connecting plate.

[0012] The beneficial effects of this invention are as follows:

[0013] 1. The same mold frame can be adjusted up and down to accommodate ferrite magnetic tile molds of various specifications, and multiple specifications of products can be produced without changing the mold frame separately;

[0014] 2. Once assembled with the press, the mold frame is fixed in place for a long time. When a new mold is put into service, only the relative position of the mold and the mold frame needs to be calibrated. The debugging cycle is reduced from 2-4 hours to less than 0.5 hours.

[0015] 3. Simple structure, low manufacturing cost, and long service life. Attached Figure Description

[0019] The present invention will now be described in further detail with reference to the accompanying drawings. These drawings are simplified schematic diagrams, illustrating only the basic structure of the invention, and therefore only show the components relevant to the invention.

[0020] Example 1: As Figures 1-2A universal mold frame for ferrite magnetic tiles includes a floating assembly and a support assembly. The support assembly includes a first support plate 5 and a second support plate 4. The first support plate 5 has multiple floating connection holes symmetrically arranged on its surface, and multiple fixing holes for fixing to a press bench 7 are arranged along its edge. The second support plate 4 is located at the center of the top surface of the first support plate 5, and the second support plate 4 and the first support plate 5 are fixedly connected by support connecting bolts 12. The floating assembly includes a floating plate 2, a floating connecting plate 8, a floating guide shaft 3, and a floating guide sleeve 6. The center of the floating plate 2 has a floating groove 15 corresponding to the contour of the second support plate 4, and the floating plate 2 is sleeved on the outside of the second support plate 4. The bottom of the floating plate 2 is provided with a floating guide shaft 3 corresponding to the floating connection hole, and a floating guide sleeve 6 is provided in the floating connection hole. The lower end of the floating guide shaft passes through the floating guide sleeve 6 and is fixedly connected to the floating connecting plate 8. The bottom of the floating connecting plate 8 is connected and fixed to the lower cylinder 10 of the press.

[0021] The first support plate 5 has six floating connection holes, which are symmetrically arranged about the long axis of the first support plate 5. Among the floating connection holes, the top of the floating guide sleeve 6 located in the four corner floating connection holes extends outward to the guide shaft protective sleeve 14. The top of the floating guide shaft 3 located in the four corner floating connection holes is screwed to the second support plate 4. The second support plate 4 is provided with square nuts 1 corresponding to the four corner floating guide shafts 3, and the top of the four corner floating guide shafts 3 is screwed to the square nuts 1.

[0022] A floating guide shaft bolt 13 is fixedly installed at the bottom center of the floating guide shaft 3. A floating connection hole is opened on the floating connecting plate 8 corresponding to the floating guide shaft bolt 13. After the floating guide shaft bolt 13 passes through the floating connection hole, a nut 9 is screwed in to fix the floating guide shaft 3 to the floating connecting plate 8.

[0023] The principle of use of this invention is as follows:

[0024] Assembly: When assembling the mold frame and the press, first, precisely align the fixing holes on the first support plate 5 with the elongated slot holes on the press stool 7 and connect them with bolts and nuts. Then, pre-fix the floating connecting plate 8 and the lower cylinder 10 of the press with bolts. Adjust the position of the bolts in the elongated slot holes to finely adjust the coaxiality of the mold frame center with the press spindle (error ≤ 0.05mm). Finally, tighten the bolts to complete the fixing. Place the lower mold in the floating slot 15, with the lower mold 15 located on the top surface of the first support plate 5.

[0025] Cavity filling: The lower cylinder 10 of the press moves upward, driving the six floating guide shafts 3 and the floating plate 2 to rise synchronously through the floating connecting plate 8. The floating plate 2 pushes the lower mold to close the cavity. At this time, the first support plate 5 and the second support plate 4 remain fixed. When the floating plate 2 rises to the preset position (triggered by the limit switch), the injection system injects material into the cavity of the mold to complete the filling. After filling, the lower cylinder 10 of the press continues to rise, so that the lower mold and the upper mold squeeze each other to complete the pressing.

[0026] Product ejection: After pressing, the lower cylinder 10 of the press moves downward, and the floating guide shaft 3, floating plate 2, and floating connecting plate 8 descend synchronously. When it descends to a certain distance (the descent distance is determined by the thickness of the product, and it can descend up to 115.4 mm, but generally 75.4 mm is sufficient to meet the ejection requirements), it descends until the top end face of the floating plate 2 is flush with the top end face of the second support plate 4. Through relative movement, the lower mold is ejected, so that the formed magnetic tile can be taken out smoothly (the ejection speed can be adjusted by the press hydraulic system, steplessly adjustable from 0.5-2 mm / s), thus avoiding product cracking.

[0027] This invention allows the same mold frame to be adapted to various specifications of ferrite magnetic tile molds through floating and vertical adjustment, enabling the production of multiple specifications of products without the need to replace the mold frame separately; the mold frame and press are fixed for a long time after one assembly, and the new mold only needs to be calibrated to adjust the relative position of the mold and the mold frame, reducing the debugging cycle from 2-4 hours to less than 0.5 hours; the structure is simple, the manufacturing cost is low, and the service life is long.

[0028] Finally, it should be noted that the above examples are merely specific embodiments of the present invention. Obviously, the present invention is not limited to the above embodiments and many variations are possible. All variations that can be directly derived or conceived by those skilled in the art from the disclosure of this invention should be considered within the scope of protection of this invention.
