Description

Technical Field

[0001] This utility model relates to the field of mold steel casting and forging technology, and in particular to a mold steel casting and forging with a quick-change mold core. Background Technology

[0002] In modern manufacturing, mold steel castings and forgings are widely used in many fields such as automobiles, aerospace, and machinery manufacturing. With the increasing diversification of market demand and the accelerated pace of product updates, higher requirements are placed on the rapid adjustment and efficient production capacity of molds. During the use of molds, the mold core, as a key component that directly participates in product forming, is frequently worn, damaged, or needs to be replaced due to product changes. Therefore, the replacement efficiency of mold cores and the overall stability of molds have become important factors affecting production efficiency and product quality.

[0003] Currently, traditional mold steel castings and forgings have many shortcomings in terms of mold core replacement. Existing mold core fixing methods are often quite complex, usually using multiple bolts or welding. Taking bolt fixing as an example, when replacing the mold core, operators need to use professional tools to unscrew a large number of bolts one by one. This process is not only time-consuming and labor-intensive, but also further increases the difficulty of disassembly due to the potentially hidden locations of the bolts and limited operating space, resulting in a significant increase in the time cost of mold core replacement. If the mold core is fixed by welding, although the connection is strong, once the mold core needs to be replaced, removing the mold core will damage other parts of the mold, making the overall mold maintenance cost high. This inconvenience in mold core replacement directly leads to long equipment downtime, seriously affecting production efficiency and increasing production costs. In response to this technical problem, this application proposes a mold steel casting and forging that allows for quick mold core replacement. Utility Model Content

[0004] The purpose of this invention is to address the shortcomings of existing technologies by proposing a mold steel casting or forging with a quick-change mold core. By pulling the lever or twisting the lever, and with the help of the synergistic effect of the threaded assembly and the limiting assembly, the fixing and limiting of the mold core can be quickly released, enabling convenient removal and replacement of the mold core. The elastic buffering effect of the spring effectively reduces the impact force when the upper and lower molds come into contact, protecting the key components of the mold.

[0005] To achieve the above objectives, the present invention provides the following technical solution:

[0026] Specifically, pulling the pull knob 22 at the middle of the front end of the fixing rod 11 causes the fixing rod 11 to move. Since the rear end of the lead screw 15 is rotatably connected to the slide plate 13 and the front end is fixedly connected to the knob 17, and the knob 17 is rotatably connected to the inner wall of the fixing rod 11, and the threaded sleeve 16 connected to the outer wall of the lead screw 15 is fixed to the front end of the lower mold 6, when the fixing rod 11 moves, under the action of the lead screw 15 and the threaded sleeve 16, the tenon 14 fixed at the rear end of the slide plate 13 moves with the slide plate 13 and disengages from the mold core 8. Then, pull the fixing plates 9 at both ends of the mold core 8 upward, and under the action of the sliding tenon 7, the mold core 8 can be easily removed from the lower mold 6 for replacement.

[0027] Reference Figure 1 , Figure 4 and Figure 5 The knob 17 is located on the inner wall of the right side of the fixed rod 11. The knob 17 is rotatably connected to the inner wall of the fixed rod 11. The rear end of the knob 17 is fixedly connected to the lead screw 15, which is rotatably connected to the front end of the slide plate 13. The outer wall of the lead screw 15 is threadedly connected to the threaded sleeve 16, which is fixedly connected to the front end of the lower mold 6. The slide rod 4 is located at the bottom end of the top plate 1 and is fixedly connected to the inner wall of the lower mold 6. A spring 5 is provided on the bottom side of the outer wall of the slide rod 4, and one end of the spring 5 is connected to the upper... At the bottom of mold 3, the other end of spring 5 is connected to the inner wall of lower mold 6. Pull rod 19 is located on the inner wall of rotating rod 18. The rear end of pull rod 19 is fixedly connected to tenon 20. Tenon 20 is slidably connected to the front end of knob 17. Spring 21 is provided on the outer wall of pull rod 19. One end of spring 21 is connected to the inner wall of rotating rod 18, and the other end of spring 21 is connected to the front end of tenon 20. Rubber strip 10 is fixedly connected to the top of mold core 8. Pull torque 22 is fixedly connected to the middle of the front end of fixed rod 11.

[0028] Specifically, pulling the lever 19 causes the tenon 20, which is fixedly connected to the rear end of the lever 19, to move and compress the spring 21, causing the tenon 20 to disengage from the limit of the knob 17. When it is necessary to reposition the knob 17 and reverse the limit, simply rotate the lever 18 to align the tenon 20 with the slot of the knob 17, and then release the force applied to the lever 19. Under the action of the spring 21, the tenon 20 will spring into the slot of the knob 17 to reposition the knob 17. When the upper mold 3 moves downward, the spring 5, which is sleeved on the bottom side of the outer wall of the slide rod 4, plays a role. One end of it is connected to the bottom of the upper mold 3, and the other end is connected to the inner wall of the lower mold 6. Through its own elastic deformation, it plays a buffering role in the descent of the upper mold 3, preventing the upper mold 3 from being damaged by collision due to excessive speed when it contacts the lower mold 6, and ensuring the integrity and stability of the mold structure. The mold core 8 can prevent molten steel from leaking out from the connection between the mold core 8 and the upper mold 3.

[0029] Working principle: The upper mold 3 is moved downward by the electric push rod 2. During the movement of the upper mold 3, the spring 5 can provide a certain buffer to prevent the upper mold 3 from being damaged due to excessive speed when it comes into contact with the lower mold 6. Then, the molten steel is injected into the mold core 8 through the injection port 23 to cast the part. When the mold core 8 needs to be replaced, the pull rod 19 is pulled to move the tenon 20 out of the limit of the knob 17. Then, the pull torque 22 is pulled. Under the action of the threaded sleeve 16 and the lead screw 15, the tenon 14 can be disengaged from the mold core 8 through the fixing rod 11, the limit rod 12 and the slide plate 13. Then, the mold core 8 is taken out from the lower mold 6 through the fixing plate 9, and then the mold core 8 can be replaced.
