[0030] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0031] In order to make the above-mentioned objects, features and advantages of the present invention more obvious and easy to understand, the present invention is further described in detail below with reference to the accompanying drawings and specific embodiments.

[0032] Reference Figure 1-Figure 7 The present invention provides a forging die rapid die changing device, comprising:

[0033] The self-locking connection mechanism comprises a connecting top plate 1 and a connecting truncated platform 5 fixedly connected to the top of the mold core 2. A connecting hole 9 is provided at the bottom of the connecting top plate 1. The connecting truncated platform 5 is adapted to the connecting hole 9. A rotating clamping piece is provided between the connecting truncated platform 5 and the connecting hole 9. Two groups of clamping blocks 8 are slidably connected in the horizontal direction in the connecting top plate 1. Two groups of slots 19 are provided on the side wall of the connecting truncated platform 5. The slots 19 are adapted to the clamping blocks 8. Two groups of bolt driving assemblies are provided in the connecting top plate 1. The two bolt driving assemblies are used to drive the clamping blocks 8 to be inserted into the slots 19.

[0034] The mold changing trolley includes a storage trolley 20. A lifting support structure is arranged on one side of the storage trolley 20. The lifting support structure includes a lifting plate 23. A turntable 26 and a movable pulley assembly are arranged on the lifting plate 23. The turntable 26 is used to drive the mold core 2 to perform horizontal deflection.

[0035] The main function of the rotating clamp is that after the connecting truncated cone 5 is inserted into the connecting hole 9, the mold core 2 can be connected to the connecting top plate 1, thereby improving the mold changing efficiency of the mold core and reducing the operation difficulty; the main function of the bolt driving assembly is to drive the clamping block 8 to insert the clamping block 8 into the slot 19 to prevent the connecting truncated cone 5 from rotating in the connecting hole 9, thereby improving the connection stability; the main function of the lifting plate 23 is to support the mold core, and drive the mold core 2 to move up or down under the action of the lifting driving member to realize the disassembly and assembly of the mold core; the main function of the turntable 26 is to drive the mold core 2 to rotate; the main function of the movable pulley assembly is to facilitate the sliding of the mold core 2 on the lifting plate 23. On the whole, the present invention sets a rotating clamping part, and by making the mold core rotate horizontally at a certain angle, the mold core can be connected and released from the connecting top plate, thereby improving the mold changing efficiency. At the same time, the clamping block is used to limit the rotation of the mold core to improve the stability of the connection. At the same time, by setting a turntable and a movable pulley assembly, the mold core can slide smoothly on the lifting plate and easily achieve angle deflection, which is convenient for the connection between the mold core and the connecting top plate.

[0036] A further optimized solution is that the rotating clamping part includes a plurality of connecting blocks 6 fixedly connected to the side wall of the connecting cone 5 at equal intervals and slide grooves 10 vertically and evenly arranged on the side wall of the connecting hole 9. The tops of the side walls of the plurality of slide grooves 10 in the same rotation direction are respectively connected to horizontally arranged transverse slide grooves 25, and the connecting blocks 6 are arranged corresponding to the slide grooves 10 and the transverse slide grooves 25.

[0037] like Figure 1 , Figure 3 and Figure 4 As shown, in this embodiment, three groups of connection blocks 6 and three groups of slide grooves 10 are provided. After the connection block 6 is aligned with the slide groove 10, the connection truncated table 5 can be inserted upward into the connection hole 9 by lifting the mold core 2 upward. Afterwards, the mold core 2 is rotated to slide the connection block 6 into the horizontal slide groove 25, and the mold core 2 is fixedly connected to the bottom of the connection top plate 1 by limiting the connection block 6 with the horizontal slide groove 25.

[0038] Further optimized solution, the driving assembly includes a first hydraulic chamber 13 horizontally opened in the connecting top plate 1, the first hydraulic chamber 13 is arranged on the side of the clamping block 8 away from the connecting hole 9, a first piston 12 is slidably connected in the first hydraulic chamber 13, and one end of the first piston 12 is fixedly connected to the clamping block 8 through the push rod 11;

[0039] It also includes a second hydraulic chamber 15 vertically opened in the connecting top plate 1, a second piston 16 is slidably connected in the second hydraulic chamber 15, the top end of the second hydraulic chamber 15 is connected to the end of the first hydraulic chamber 13 away from the connecting hole 9 through an oil passage 14, the first piston 12, the first hydraulic chamber 13, the second piston 16, the second hydraulic chamber 15 and the oil passage 14 are filled with hydraulic oil, and the side of the second piston 16 away from the oil passage 14 is pushed by a bolt fastener arranged between the connecting top plate 1 and the core 2.

[0040] like Figure 1 and Figure 2 As shown, the mold core 2 is rotated to be in the correct installation position, at which time, the connecting block 6 slides into the horizontal slide groove 25. Afterwards, the second piston 16 is pushed to move in the direction of the oil passage 14 by the bolt fastener, and the second piston 16 squeezes the hydraulic oil and uses the pressure of the hydraulic oil to push the first piston 12 to move in the direction of the connecting hole 9. At this time, the first piston 12 pushes the block 8 to move into the slot 19 through the push rod 11 and inserts into the slot 19, preventing the connecting round table 5 from rotating and increasing the firmness of the connection.

[0041] According to a further optimized solution, a slideway 7 is provided in the connecting top plate 1, one side of the two groups of clamping blocks 8 are respectively slidably connected in the slideway 7 through a stopper, and a second spring is abutted between the two stoppers.

[0042] When the mold core needs to be removed and the bolt fasteners are removed, the second spring can push the two clamping blocks 8 outwards by its own elastic force, so that the clamping blocks 8 are disengaged from the slots 19 .

[0043] A further optimized solution is that the bolt fastener includes a fixing bolt 18, a threaded hole 3 opened at the bottom of the connecting top plate 1 and a through hole 4 opened on the core 2, the threaded hole 3 is connected to the end of the second hydraulic chamber 15 away from the oil passage 14, the threaded end of the fixing bolt 18 passes through the through hole 4 and the threaded hole 3 and pushes the second piston 16 to move in the direction of the oil passage 14.

[0044] like Figure 1 and Figure 2 As shown, when the mold core 2 is in the correct connection position, the threaded hole 3 is aligned with the through hole 4. At this time, the fixing bolt 18 is screwed into the threaded hole 3. As the fixing bolt 18 is screwed, the threaded end of the fixing bolt 18 rises and pushes the second piston 16. When the fixing bolt 18 is tightened, the fixing bolt 18 can also serve to assist in connecting the mold core 2 and the top plate 1.

[0045] Further optimizing the scheme, one side of the storage cart 20 is opened, and two sets of sliding rollers are arranged from top to bottom in the storage cart 20, and the upper and lower sliding rollers are used to store the old mold and the new mold respectively;

[0046] The lifting support structure is arranged on the opening side of the storage vehicle 20. A lifting drive component for controlling the height of the lifting plate 23 is arranged in the lifting support structure. A position locking component is arranged between the movable pulley assembly and the lifting drive component. When the movable pulley assembly is in a high position, the mold core 2 contacts the movable pulley assembly. When the movable pulley assembly is in a low position, the mold core 2 contacts the turntable 26. The turntable 26 is used to drive the mold core 2 to rotate.

[0047] The main function of the sliding roller group is to facilitate the sliding of the mold core 2 in the storage cart 20, and then to facilitate the taking and placing of the mold core 2 from the storage cart 20. By setting up the storage cart, the mold changing trolley can store new mold cores and old mold cores in one mold change, avoiding the problem of reduced efficiency caused by reciprocating taking and placing of new and old mold cores.

[0048] According to a further optimization scheme, the storage cart 20 is provided with an upper and lower storage plate, and two sets of sliding rollers are respectively arranged on the upper and lower storage plates, and the mold core 2 can be pushed into the storage cart 20 or taken out from the storage cart 20 by horizontal pushing and pulling.

[0049] A further optimized solution is that the lifting bracket structure includes two groups of top beams 21 horizontally fixedly connected to the top of the open end of the storage cart 20, the two groups of top beams 21 are respectively arranged on both sides of the storage cart 20, and the bottoms of the two groups of top beams 21 are respectively vertically fixedly connected with two groups of support columns 22, the bottoms of the support columns 22 are provided with wheels 24, the lifting drive components are arranged in the support columns 22, and the lifting plate 23 is arranged between the four groups of lifting drive components.

[0050] like Figure 5 As shown, the lifting space of the lifting plate 23 can be avoided between the two groups of top beams 21, which can ensure that the lifting plate 23 can smoothly enter the forging equipment to perform the mold changing work.

[0051] A further optimized solution is that the lifting drive member includes two groups of sprockets 27 rotatably connected to the top and bottom of the inner side of the support column 22, a chain 28 is wound around the two sprockets 27, the movable pulley assembly is fixedly connected to the chain 28, and a rotating drive member is arranged between a sprocket 27 and the support column 22.

[0052] As a further optimization scheme, the rotating driving member can be in the form of a motor and a reducer, which are used to drive a sprocket 27 to rotate, so that the chain 28 can drive the lifting plate 23 to move up and down.

[0053] According to a further optimized solution, the movable pulley assembly includes two sets of horizontally arranged connecting rods 31, one end of the two sets of connecting rods 31 is fixedly connected with a fixing bar 30, the top of the fixing bar 30 is rotatably connected with a plurality of balls 33, and the other ends of the two connecting rods 31 are respectively fixedly connected with two chains 28 located on the same side;

[0054] Two sets of first grooves that pass through the connecting rod 31 are formed on the side wall of the lifting plate 23, and a spring 32 is abutted between the top of the connecting rod 31 and the first groove. A second groove is formed downward from the top of the lifting plate 23, and the fixing bar 30 is located in the second groove.

[0055] like Figure 5 and Figure 6 As shown, when the position locking assembly does not lock the fixed bar 30, when the chain 28 drives the connecting rod 31 to rise, the connecting rod 31 squeezes the spring 32 and causes the fixed bar 30 to rise relative to the lifting plate 23, so that the height of the ball 33 is higher than the turntable 26. At this time, the operator can easily push the core 2 onto the lifting plate 23 or push it out from the lifting plate 23 through the ball.

[0056] When the position locking assembly locks the fixing bar 30 and the chain 28 drives the connecting rod 31 to rise, the fixing bar 30 directly lifts the lifting plate 23 together through the position locking assembly, so that the height of the ball 33 does not exceed the height of the turntable 26. At this time, the mold core 2 can be controlled to rotate horizontally.

[0057] A further optimized solution is that the position locking assembly includes a plurality of through holes horizontally opened at the bottom of the side wall of the fixing bar 30 and a plurality of limit columns 34 horizontally slidably connected to the lifting plate 23. The plurality of limit columns 34 are arranged corresponding to the plurality of through holes. One end of the limit column 34 is threadedly connected to a screw rod 35, and the end of the screw rod 35 away from the limit column 34 is transmission-connected to a second motor 36.

[0058] like Figure 6 As shown, the cross section of the limiting column 34 is set to be rectangular. When the fixing bar 30 needs to be locked in the second groove, the second motor 36 can drive the screw rod 35 to rotate, and the limiting column 34 is pushed into the through hole on the fixing bar 30 through the threaded transmission of the screw rod 35 to achieve the locking of the fixing bar 30. When the second motor 36 drives the limiting column 34 to be pulled out of the through hole, the fixing bar 30 and the lifting plate 23 can move relative to each other.

[0059] According to a further optimized solution, a first motor 29 is disposed in the lifting plate 23 , and the first motor 29 is transmission-connected to the bottom of the turntable 26 , and the first motor 29 is used to drive the turntable 26 to rotate.

[0060] like Figure 6 As shown, the output shaft of the first motor 29 can be connected to the bottom center of the turntable 26 through a reducer. By controlling the rotation of the first motor 29, the turntable 26 can be controlled to deflect in the horizontal direction.

[0061] The working process of this embodiment is as follows: when the mold core needs to be replaced, the operator first places the mold core 2 to be replaced in the lower roller group of the storage vehicle. After that, the mold changing trolley is driven to the forging equipment, the lifting plate 23 is first lowered to contact the ground, and then the second motor 36 is controlled to rotate so that the limit column 34 is inserted into the perforation. After that, the lifting plate 23 is raised and the storage vehicle 20 is driven forward, and the lifting plate 23 is placed under the mold core 2 to be replaced, and the turntable 26 is made to fit the bottom of the mold core 2. After that, the fixing bolt 18 is unscrewed, and the turntable 26 is driven to drive the mold core 2 to rotate, so that the connecting block 6 rotates to the slide slot 10, and the lifting plate 23 is lowered to drive the mold core 2 to descend and be removed from the connecting top plate 1. The lifting plate 23 is lowered until it contacts the ground, the second motor 36 is controlled to reverse, the limiting column 34 is pushed out from the perforation, and the lifting plate 23 is lifted again. At this time, the ball 33 contacts the bottom of the mold core, the lifting plate 23 is lifted to a suitable height, and the replaced mold core 2 is pushed into the upper sliding roller group of the storage cart 20.

[0062] Afterwards, lower the lifting plate 23 again, push the new mold core 2 onto the lifting plate 23, continue to lower until the lifting plate 23 contacts the ground, control the second motor 36 to rotate, insert the limit column 34 into the through hole of the fixing bar 30, lift the lifting plate 23 to the appropriate position, align the connecting block 6 with the slide groove 10, lift it up until the connecting round table 5 is inserted into the connecting hole 9, then control the turntable 26 to straighten the mold core 2, slide the connecting block 6 into the horizontal slide groove 25, and then use the fixing bolt 18 to penetrate the through hole 4 and screw it into the threaded hole 3, push the block 8 into the slot 19, and use the fixing bolt 18 to assist in fixing the mold core 2.

[0063] In the description of the present invention, it should be understood that the terms "longitudinal", "lateral", "up", "down", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inside" and "outside" etc., indicating orientations or positional relationships, are based on the orientations or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the present invention, and do not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be understood as a limitation on the present invention.
