DETAILED DESCRIPTION Example

[0023] When disassembling the core body 3 of some existing molds, the user needs to pull the fixing posts at two different positions until the fixing posts are separated from the mounting plate. Due to the action of the reset spring on the fixing post, the user needs to keep pulling after pulling the fixing post, otherwise the reset spring will drive the fixing post to combine with the mounting plate again after letting go. When the two fixing posts are separated from the corresponding mounting plates, the user also needs to turn the knob on one side of the base until the mounting plate is separated from the mounting block. Obviously, the entire operation of disassembling the core body 3 cannot be completed by one person, and when installing the core body 3, since the reset spring has reset the fixing post, the user needs to pull the fixing post again. The operation is very troublesome and cannot achieve the effect of quickly replacing the core body 3, which is not conducive to improving the replacement efficiency of the core body 3. The following solution is used to solve this problem.

[0024] See also Figures 1 to 5 A mold with a replaceable mold core for forging upper and lower covers in the air, comprising a base 1, an installation groove 2 is provided on the upper surface of the base 1, a mold core body 3 is movably connected inside the installation groove 2, an electric telescopic rod 4 is fixedly connected to the top of the base 1, there are two electric telescopic rods 4, which are symmetrically arranged on both sides of the mold core body 3, an upper mold 5 is fixedly connected to the output end of the electric telescopic rod 4, a rack 6 is fixedly connected to the bottom of the upper mold 5 and located on one side of the electric telescopic rod 4, the rack 6 vertically penetrates the base 1 and extends to the inside of the base 1, the rack 6 is slidably connected to the base 1, and a gear 7 is rotatably connected to the inside of the base 1, and the gear 7 is connected to the rack 6 The upper mold 5 is meshingly connected, and can drive the rack 6 to move up and down, thereby driving the gear 7 to rotate. The outer sliding connection of the gear 7 is provided with an insert block 8, which vertically penetrates the base 1 and extends to the inside of the mounting groove 2. The insert block 8 is slidably connected to the base 1, and the corresponding two side edges of the core body 3 are provided with slots 9 used in conjunction with the insert block 8. The corresponding two side edges of the gear 7 are provided with slide grooves 10, and the inner sliding connection of the slide groove 10 is provided with a first slide bar 11, which is fixedly connected to the insert block 8. When the gear 7 rotates, the slide groove 10 and the first slide bar 11 can be used to drive the insert block 8 to move, so that the insert block 8 is combined with or separated from the slot 9.

[0025] The slide groove 10 includes a first groove 12 and a second groove 13, the first groove 12 is connected to the second groove 13, the first groove 12 is an arc-shaped structure, and the second groove 13 is a long strip structure. The center of the first groove 12 of the arc-shaped structure is the same as the center of the gear 7, and the radius of the second groove 13 is staggered with the radius of the gear 7. When the first slide bar 11 is located in the first groove 12, the rotation of the gear 7 will not squeeze the first slide bar 11. When the first slide bar 11 is located in the second groove 13, the rotation of the gear 7 will squeeze the first slide bar 11, thereby driving the plug 8 to move.

[0026] A first bevel 14 is provided on the outer side of the plug block 8 away from the gear 7. The first bevel 14 is provided at two upper and lower positions on the same side of the plug block 8 and is symmetrically distributed, so that the cross-section of the side of the plug block 8 is an isosceles trapezoidal structure, which is conducive to the plug block 8 entering the slot 9 and combining with it.

[0027] The utility model uses the following steps: when the mold with replaceable mold core for forging upper and lower covers is in use, if the mold core body 3 needs to be disassembled, the user only needs to control the electric telescopic rod 4 to drive the upper mold 5 that has been separated from the mold core body 3 to continue to move upward, and the upper mold 5 will drive the gear 7 in the base 1 to rotate forwardly through the rack 6. At this time, the first slide bar 11 originally located in the first groove 12 will begin to enter the second groove 13, and squeeze the first slide bar 11 through the inner wall of the second groove 13, so that the gear 7 drives the plug block 8 away from the slot 9 through the second groove 13 and the first slide bar 11, until the plug block 8 is completely separated from the slot 9. At this time, the user can pull the mold core body 3 out of the installation slot 2, and after the mold core body 3 to be replaced is installed into the installation slot 2, the electric telescopic rod 4 is controlled to drive The core body 3 moves downward, at which time the rack 6 drives the gear 7 to rotate in the opposite direction, and uses the second groove 13 and the first slide bar 11 to drive the insert block 8 to approach the slot 9 until the insert block 8 is combined with the slot 9. When the object is subjected to the die-casting treatment, the upper mold 5 needs to continue to move downward, and the rack 6 will continue to drive the gear 7 to rotate in the opposite direction. However, as the gear 7 rotates in the opposite direction, the first slide bar 11 will enter the first groove 12 from the second groove 13. The first groove 12 is an arc-shaped structure, and the center of the circle is the same as that of the gear 7. Therefore, even if the gear 7 continues to rotate in the opposite direction, the first slide bar 11 will not be squeezed, so that the insert block 8 can remain combined with the slot 9, and at the same time will not affect the downward movement of the upper mold 5 and the die-casting treatment of the object, thereby achieving the purpose of quickly replacing the core body 3, and the operation is simple and labor-saving. Example

[0028] After the insert block 8 is combined with the slots 9 on both sides of the core body 3, the installation of the core body 3 can be completed. In order to further improve the stability of the core body 3, the following solution is used to solve this problem.

[0029] See also Figures 3 to 5, the basis of the combined implementation is different in that a third groove 15 is provided at one end of the plug block 8 away from the gear 7, a slider 16 is slidably connected inside the third groove 15, a spring 17 is provided between the slider 16 and the third groove 15, one end of the spring 17 is fixedly connected to the plug block 8, and the other end of the spring 17 is fixedly connected to the slider 16, a fourth groove 18 is provided on the upper surface of the plug block 8, the fourth groove 18 is communicated with the third groove 15, a block 19 is slidably connected inside the fourth groove 18, the block 19 is slidably connected to the slider 16, and an inclined groove 20 is provided inside the slider 16 and on the corresponding two sides of the block 19, the inclined groove The inner sliding connection of 20 is provided with a second slide bar 21, and the second slide bar 21 is fixedly connected to the block 19. A card slot 22 used in conjunction with the card block 19 is provided inside the core body 3, and the card slot 22 is connected to the slot 9. The card slot 22 is arranged at the top position of the inner wall of the slot 9. When the plug block 8 moves and enters the slot 9, the slide block 16 will first contact and press against the inner wall of the slot 9. As the plug block 8 continues to move, the second slide bars 21 on both sides of the card block 19 will be squeezed by the inclined groove 20 on the slide block 16, so that the card block 19 moves upward and engages with the card slot 22, thereby further limiting the core body 3 and ensuring the stability of the core body 3 in the mounting groove 2.

[0030] A second inclined surface 23 is provided on the top of the block 19 near the spring 17. The second inclined surface 23 makes the upper surface of the block 19 smaller than the slot 22. When the block 19 has not completely moved to the bottom of the slot 22, even if the block 19 has started to move upward, the block 19 will not fail to engage with the slot 22.

[0031] The slider 16 is a U-shaped structure. The block 19 can move up and down on the inner side of the fourth groove 18, and the slider 16 slides back and forth on the outer side of the block 19. The U-shaped slider 16 can prevent motion interference between itself and the block 19, ensuring that both the slider 16 and the block 19 can move smoothly.

[0032] Usage steps of the utility model: when the mold with replaceable mold core for forging upper and lower covers with air suspension is in use, after the insert block 8 enters the slot 9, the slider 16 on the insert block 8 will abut against the inner wall of the slot 9, as the insert block 8 continues to enter the slot 9, the spring 17 will be compressed, and the block 19 will move to the bottom of the slot 22. During the process, the second slide bar 21 on both sides of the block 19 will be squeezed by the inclined groove 20 on the slide bar 16, so that the block 19 starts to move upward in the third groove 15 and engages tightly with the slot 22, thereby improving the stability of the core body 3 in the installation groove 2 through the block 19 and the slot 22. When the insert block 8 is separated from the slot 9, the elastic force of the compressed spring 17 will drive the slider 16 to reset, and the slider 16 drives the block 19 to move downward and separate from the slot 22 through the inclined groove 20 and the second slide bar 21.
