[0032] Combine Figures 1 to 6 As shown, the utility model discloses a mold capable of realizing rapid mold change, comprising:

[0033] A movable mold 11 and a fixed mold 12; the upper surfaces of the movable mold 11 and the fixed mold 12 are provided with a hanging ring 13;

[0034] Multiple quick connection structures for connecting the movable mold 11 and the fixed mold 12, the quick connection structures including a first boss 21, a second boss 22, a third boss 23, a connecting plate 24 and a stopper 25, wherein the first boss 21 is provided on the fixed mold 12, the second boss 22 is provided on the movable mold 11; and the third boss 23 is provided on the movable mold 11;

[0035] When the movable mold 11 and the fixed mold 12 need to be connected, the connecting plate 24 is simultaneously sleeved on the first protrusion 21 and the third protrusion 23. When the movable mold 11 and the fixed mold 12 need to be separated, the connecting plate 24 is simultaneously sleeved on the second protrusion 22 and the third protrusion 23. The limiting member 25 is used to keep the connecting plate 24 in the sleeved state.

[0036] Compared to the prior art, the present invention innovatively incorporates a quick-connect structure on the mold, enabling quick connection between the movable mold 11 and the fixed mold 12. During lifting, the operator utilizes the quick-connect structure to securely connect the movable mold 11 and the fixed mold 12, integrating the two molds. Multiple slings are threaded through multiple lifting rings 13, with both ends of the slings extending upward. The hooks of the lifting equipment are then used to hook all of the slings, thereby completing the mold lifting process. The present invention utilizes a quick-connect structure to securely connect the fixed mold 12 and the movable mold 11, allowing them to be lifted together, improving the efficiency of mold transfer.

[0037] Furthermore, in order to simplify the structure of the connecting plate 24, the connecting plate 24 only needs two through holes to simultaneously adapt to the diameters of the first boss 21, the second boss 22 and the third boss 23. In the present utility model, the diameters of the first boss 21 and the second boss 22 are the same; the distance between the third boss 23 and the first boss 21 is equal to the distance between the third boss 23 and the second boss 22; the connecting plate 24 is provided with a first through hole adapted to the diameter of the first boss 21 and a second through hole adapted to the diameter of the third boss 23. By limiting the socketing of the second through hole and the third boss 23, the first through hole and the first boss 21 and the second boss 22 are socketed. When the movable mold 11 and the fixed mold 12 are connected, the first through hole is socketed with the first boss 21; when the movable mold 11 and the fixed mold 12 are separated, the first through hole is socketed with the second boss 22.

[0038] Furthermore, the front end of the third boss 23 protrudes from the connecting plate 24, and a groove 231 is provided in the middle of the front end of the third boss 23; the limiting member 25 is an L-shaped thin plate; the L-shaped thin plate has a first thin plate portion 251 and a second thin plate portion 252 vertically connected to the first thin plate portion 251; the L-shaped thin plate is located at the groove 231, and the first thin plate portion 251 is rotatably connected to the third boss 23 via a first pin 26.

[0039] like Figure 2 As shown, Figure 2 Figure 2 shows the state of the quick connection structure after the movable mold and the fixed mold are connected. When the L-shaped thin plate is only subjected to gravity, the first thin plate portion 251 is arranged upright, with the upper and lower sides of the first thin plate portion 251 protruding from the third protrusion 23, and the second thin plate portion 252 is arranged horizontally and located on the side close to the connecting plate 24.

[0040] like Figure 3 As shown, Figure 3It is a state diagram of the L-shaped thin plate in the extended position; when the L-shaped thin plate is rotated by an external force, the L-shaped thin plate has an extended position relative to the connecting plate 24. When the L-shaped thin plate is in the extended position, the first thin plate portion 251 is horizontally arranged, and the upper and lower sides of the first thin plate portion 251 do not protrude from the third protrusion 23 at this time, and the second thin plate portion 252 is upright; when the connecting plate 24 is against the upright second thin plate portion 252, the connecting plate 24 is separated from the first protrusion 21 and the second protrusion 22.

[0041] With the above-mentioned structural scheme, when the L-shaped thin plate is only subjected to the action of gravity, since the upper and lower sides of the first thin plate part 251 protrude from the third protrusion 23, this acts as a limit for the connecting plate 24. When the limiting plate moves toward the direction of the L-shaped thin plate, the side of the first thin plate part 251 facing the connecting plate 24 can limit the connecting plate 24. The connecting plate 24 can only move to a position where it is against the side of the connecting plate 24. When the mold is hoisted, the connecting plate 24 can maintain a socketed state with the first protrusion 21 and the third protrusion 23, so that the movable mold 11 and the fixed mold 12 remain connected; or after the movable mold 11 and the fixed mold 12 are separated, the connecting plate 24 can maintain a socketed state with the first protrusion 21 and the third protrusion 23, so as to avoid the loss of the connecting plate 24. The structure is simple and stable and reliable.

[0042] When the movable mold 11 and the fixed mold 12 need to be changed from the connected state to the separated state, or from the separated state to the connected state, the L-shaped thin plate is rotated to the pulled-away position so that the upper and lower sides of the first thin plate portion 251 do not protrude from the third protrusion 23. In this way, the connecting plate 24 moves outward a greater distance, allowing the second through hole of the connecting plate 24 to be separated from the first protrusion 21 or the second protrusion 22. Only in this way can the connecting plate 24 be rotated with the third protrusion 23 as the rotation center to realize the conversion of the position of the second through hole of the connecting plate 24; and since the second thin plate portion 252 is upright when in the pulled-away position, the connecting plate 24 can only move to a position at which it abuts against the second thin plate portion 252, so that the connecting plate 24 can remain sleeved with the second protrusion 22.

[0043] Furthermore, since the first boss 21 protrudes from the surface of the fixed mold 12, and the mold is usually gradually cut and milled using machine tools, in order to save the material cost of the fixed mold 12, the first boss 21 and the fixed mold 12 are preferably connected in a detachable manner. Considering that the first boss 21 needs to bear the weight of the mold when the mold is hoisted, in the utility model, in order to achieve the detachable connection between the first boss 21 and the fixed mold 12 and make the connection of the first boss 21 stable and reliable, a first concave hole is provided on the side of the fixed mold 12 facing the quick connection structure, and the first boss 21 is installed in the first concave hole. A first pin hole is provided on the side of the fixed mold 12 facing the movable mold 11, and the first pin hole is connected to the first concave hole; a second pin shaft 27 is installed in the first pin hole, which is penetrated by the first boss 21. In this way, the first boss 21 is limited by the first pin shaft 26, and the first boss 21 cannot rotate, and the length protruding from the surface of the fixed mold 12 remains fixed.

[0044] Furthermore, since the third boss 23 protrudes from the surface of the movable mold 11, and the mold is usually gradually cut and milled by machine tools, in order to save the material consumption cost of the fixed mold 12, the third boss 23 and the movable mold 11 are preferably connected in a detachable manner. Considering that the third boss 23 needs to bear the weight of the mold when the mold is hoisted, in the utility model, in order to achieve the detachable connection between the third boss 23 and the movable mold 11 and make the connection of the third boss 23 stable and reliable, a third recessed hole is provided on the side of the movable mold 11 facing the quick connection structure, and the third boss 23 is installed in the third recessed hole; a third pin hole is provided on the side of the movable mold 11 facing the fixed mold 12, and the third pin hole is connected to the third recessed hole; a third pin shaft 28 is installed in the third pin hole, which is penetrated by the third boss 23. In this way, the third boss 23 is limited by the third pin shaft 28, and the third boss 23 cannot rotate, and the length protruding from the surface of the movable mold 11 remains fixed.

[0045] Furthermore, if Figure 5 and Figure 6 As shown, Figure 5 This is a diagram of the state when the first through hole of the connecting plate is sleeved on the second boss; because the second through hole of the connecting plate 24 is sleeved on the second boss 22, it is only for supporting the connecting plate 24 and preventing the connecting plate 24 from swinging. The second through hole only needs to bear the weight of the connecting plate 24, unlike the first through hole, which needs to bear the weight of the mold during lifting in addition to the weight of the connecting plate 24. Therefore, in the utility model, the screw fastener 29 is passed through the second boss 22 in the front-to-back direction and is threadedly connected to the movable mold 11, and only the weight of the connecting plate 24 itself needs to be borne, and the structure is simple.

[0046] The above description is an explanation of the utility model, not a limitation of the utility model. The scope of the utility model is defined by the claims. Any form of modification can be made within the scope of protection of the utility model.

[0047] The present invention is not limited to the above-mentioned embodiments. If various changes or modifications to the present invention do not depart from the spirit and scope of the present invention, and if these changes and modifications fall within the scope of the claims and equivalent technologies of the present invention, the present invention is also intended to include these changes and modifications.
