[0032] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0033] In the description of the present invention, it is necessary to understand that the terms "upper", "lower", "front", "back", "left", "right", "top", "bottom", "inside", "outside", etc. indicate orientations or positional relationships based on the orientations or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation on the present invention.

[0034] like Figure 1-6 As shown, a rubber-metal assembly inlaid mold structure includes a bottom plate 1 and a pressing plate 13. Support rods 12 are vertically arranged at four corners of the upper surface of the bottom plate 1. A top plate 11 is arranged at the upper end of the support rods 12. The top plate 11 is horizontally located above the bottom plate 1. The pressing plate 13 is horizontally located between the bottom plate 1 and the top plate 11. The four corners of the pressing plate 13 are respectively inserted between the four support rods 12. An electric push rod 12 is vertically arranged on the top plate 11. The electric push rod 12 faces downward. The end of the electric push rod 12 is fixed to the upper surface of the pressing plate 13. The extension and retraction of the electric push rod 12 can drive the pressing plate 13 to move up and down.

[0035] A supporting mold base 15 is provided on the upper surface of the bottom plate 1, and a plurality of circular first supporting platforms 2 are provided on the upper surface of the supporting mold base 15. A circular second supporting platform 21 is provided on the upper surface of the first supporting platform 2. The first supporting platform 2 and the second supporting platform 21 are concentric. Four limiting blocks 22 are provided on the surface of the second supporting platform 21. When the inner rubber ring 5 is sleeved on the second supporting platform 21, the four limiting blocks 22 can fix the inner rubber ring 5.

[0036] A lower die seat 16 is provided on the lower surface of the pressing plate 13, and a plurality of mounting plates 3 are installed on the lower surface of the lower die seat 16 by bolts. The bolts pass through the through holes 36 and are then screwed into the lower die seat 16. Six slide seats 4 are slidably installed on the lower surface of the mounting plate 3. The six slide seats 4 are evenly distributed on the lower surface of the mounting plate 3 in a surrounding shape. Six back plates 32 are also provided on the lower surface of the mounting plate 3. The back plates 32 are aligned with the slide seats 4. A telescopic rod 34 and a spring 35 are provided between the back plates 32 and the slide seats 4. The spring 35 is located around the telescopic rod 34. When the slide seat 4 is squeezed, it can move toward the back plate 32. During the movement, the spring 35 can be squeezed, so that the spring 35 has a reverse thrust on the slide seat 4.

[0037] The second support platform 21 is located entirely below the area between the six slide seats 4 , so that when the inner rubber ring 5 is fixed around the second support platform 21 and the outer metal ring 6 is fixed between the six slide seats 4 , the outer metal ring 6 just faces the inner rubber ring 5 below.

[0038] The slide 4 is in an inverted "L" shape, and two slide bars 41 are symmetrically arranged on the upper surface of the slide 4. The slide bars 41 are arranged along the length direction of the horizontal part of the slide 4. A slide groove 31 is arranged on the lower surface of the mounting plate 3. The slide bar 41 is slidably installed in the slide groove 31. The cross-sections of the slide bar 41 and the slide groove 31 are both "T"-shaped. The slide bar 41 moves in the slide groove 31 to guide the movement of the slide 4. The "T"-shaped slide bar 41 and the slide groove 31 can make the slide 4 fit on the lower surface of the lower die seat 16 and will not fall off.

[0039] The back plate 32 faces the vertical portion of the slide 4, one end of the telescopic rod 34 is arranged on the surface of the back plate 32 close to the slide 4, and the other end is arranged on the surface of the slide 4 close to the back plate 32, one end of the spring 35 is arranged on the surface of the back plate 32 close to the slide 4, and the other end is arranged on the surface of the slide 4 close to the back plate 32, there are two telescopic rods 34 and springs 36, which are symmetrically arranged between the slide 4 and the back plate 32, the telescopic rod 34 supports the spring 36, so that the spring 36 will not bend and droop, and the spring 36 can generate a forward thrust on the slide 4 to fix the inner rubber ring 5.

[0040] A plurality of reinforcing ribs 33 are arranged between the side of the back plate 32 facing away from the slide seat 4 and the upper surface of the mounting plate 3, so that the structural strength between the back plate 32 and the mounting plate 3 is relatively strong, and the back plate 32 is not easily deformed under the thrust of the spring 35.

[0041] A plurality of anti-skid grooves 42 are evenly and evenly arranged at equal intervals on one side of the slide seat 4 close to the center of the mounting plate 3, so that when the slide seat 4 squeezes the outer metal ring 6, the anti-skid grooves 42 can increase the friction force, and the outer metal ring 6 is fixed more firmly. An inclined surface 43 is arranged on the lower edge of one side of the slide seat 4 close to the center of the mounting plate 3, so that the lower end of the slide seat 4 is slightly open, which makes it convenient to fix the outer metal ring 6 between the six slide seats 4.

[0042] The four limit blocks 22 are evenly arranged around the second support platform 21 at equal intervals. The thickness of the limit blocks 22 gradually increases from top to bottom. The limit blocks 22 are made of rubber. In this way, when the inner rubber ring 5 is put downward on the second support platform 21, the inner surface of the inner rubber ring 5 can be put on the outside of the four limit blocks 22. The limit blocks 22 play a role in firmly fixing the inner rubber ring 5.

[0043] The lower surface of the mounting plate 3 is further provided with six through holes 36 penetrating the mounting plate 3. The six through holes 36 are evenly distributed around the lower surface of the mounting plate 3 at equal intervals. The six through holes 36 and the six slide seats 4 are staggered. In this way, bolts are passed through the through holes 36 and screwed into the lower die seat 16, so that the various positions of the mounting plate 3 are fixed more firmly.

[0044] There are four electric push rods 14, which are symmetrically distributed on the top plate 11 in front, back, left and right directions. A reinforcing rib block is arranged between the surface of the cylinder of the electric push rod 14 and the upper surface of the top plate 11, so that the structural strength between the electric push rod 14 and the top plate 11 is good. The four electric push rods 14 can generate a relatively strong downward pressure on each position of the lower surface of the pressure plate 13.

[0045] The surfaces of the six slide seats 4 close to the center of the mounting plate 3 are all facing the center of the mounting plate 3 , and the center of the mounting plate 3 is aligned with the center of the second support platform 21 in vertical alignment.

[0046] Multiple first support platforms 2 are evenly distributed along the length and width directions of the upper surface of the support mold base 15, and multiple mounting plates 3 are evenly distributed along the length and width directions of the lower surface of the lower pressure mold base 16; in this way, more inner rubber rings 5 ​​can be placed on the second support platforms 21 at one time.

[0047] In summary: the extension and retraction of the electric push rod 14 can drive the pressing plate 13 and the lower die seat 16 to move up and down. The four corners of the pressing plate 13 are inserted into the support rod 12, and the support rod 12 guides the up and down movement of the pressing plate 13 and the lower die seat 16; the mounting plate 3 and the second support platform 21 are aligned up and down, and the second support platform 21 is just located in the area between the six slide seats 4;

[0048] When inlaying, the inner rubber ring 5 is put on the second support platform 21 and the first support platform 2, and the four limit blocks 22 can slightly tighten the inner rubber ring 5, so that the inner rubber ring 5 can be relatively stably fixed on the second support platform 21, and the outer metal ring 6 is clamped between the six slide seats 4;

[0049] The slide 4 can slide on the mounting plate 3, and the slide 4 is connected to the back plate 32 through the telescopic rod 34 and the spring 35. When the outer metal ring 6 is inserted into the position between the six slides 4, the slide 4 can move toward the back plate 32, and the area between the six slides 4 becomes larger, which makes it easier for the outer metal ring 6 to be placed between the six slides 4. When the outer metal ring 6 is placed, the slide 4 can be firmly attached to the outer surface of the outer metal ring 6 under the action of the reverse thrust of the spring 35, and the anti-slip pattern 42 can increase the friction between the slide 4 and the outer metal ring 6; in this way, the outer metal ring 6 is firmly fixed between the six slides 4;

[0050] The electric push rod 14 extends, which can drive the pressing plate 13 and the lower die seat 16 to move downward, and the mounting plate 3, the slide seat 4 and the fixed outer metal ring 6 also move downward, and the inner wall of the outer metal ring 6 just faces the outer wall of the inner rubber ring 5 below, so that when the outer metal ring 6 moves downward, the outer metal ring 6 just fits in the outer wall of the inner rubber ring 5, and when the electric push rod 14 retracts, the mounting plate 3 and the six slide seats 36 move upward, and the outer metal ring 6 stays on the outer wall of the inner rubber ring 5;

[0051] The operator can remove the embedded outer metal ring 6 and inner rubber ring 5 from the second support platform 21 together; then put the new inner rubber ring 5 on the second support platform 21, fix the new outer metal ring 6 between the six slide seats 4, and embed and assemble them again; the device can embed more inner rubber rings 5 ​​and outer metal rings 6 at one time, the embedding and assembling efficiency is high, and the operation is also convenient.

[0052] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto.
