[0021] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and should not be construed as limiting the present invention.

[0022] The embodiments of this utility model will be described below based on its overall structure.

[0023] Please see Figures 1-4 A quick-change device for casting molds includes a mold frame 1 and a mold body 2. A mounting groove is provided on one side of the mold frame 1, into which the mold body 2 can be detachably inserted. A pressure groove 5 is provided on the top of the mold body 2. A die hole is provided on the top of the mold frame 1 corresponding to the pressure groove 5. A support frame 6 is mounted on the top of the mold frame 1, and a press 7 is mounted on the support frame 6 above the die hole. Elastic fixing components are provided between the two sides of the mold body 2 and the mounting groove. The elastic fixing components include fixing pins 4 and support springs 3. Pin holes penetrating the mold frame 1 are provided on both sides of the mounting groove. Sliding grooves are provided on both sides of the mold body 2 corresponding to the pin holes. Fixing pins 4 are slidably disposed within the sliding grooves, with one end of the fixing pin 4 extending out of the sliding groove and inserting into the corresponding hole. The corresponding pin hole has a support spring 3 at the other end. The mold frame 1 is movably connected to the mold body 2, and the fixing pin 4 forms a telescopic structure with the mold body 2 through the support spring 3. The fixing pin 4 is symmetrically arranged with the central axis of the mold body 2 as the center, and the fixing pin 4 is engaged with the mold frame 1. The pressure groove 5 is set at the center position of the mold body 2. The support frame 6 is welded to the mold frame 1. By setting the mold frame, mold body, support spring and fixing pin, the fixing pin is pressed inward. Then the mold body is inserted into the appropriate position in the mold frame. At this time, the fixing pin is pushed out by the elastic force of the support spring, so that the fixing pin is engaged with the mold frame. Compared with the traditional bolt fixing method, the replacement of the mold body is more convenient.

[0024] Please see Figures 1-4A quick-change device for casting molds includes a mold set 1 with a mold ejection assembly on the side away from the mounting slot. The mold ejection assembly includes a push plate 8 and an extrusion plate 10. The push plate 8 is located on the outside of the mold set 1, and the extrusion plate 10 is located in the mounting slot on the side of the mold body 2 near the push plate 8. A push rod is fixedly connected to the extrusion plate 10. The push rod slides through the mold set 1 and is fixedly connected to the push plate 8. A return spring 9 is sleeved on the push rod in the mounting slot. One end of the return spring 9 is fixedly connected to the extrusion plate 10, and the other end is fixedly connected to the inner wall of the mounting slot. A press 7 and... The pressure groove 5 is vertically set, and the push plate 8 forms a telescopic structure with the mold frame 1 through the return spring 9. The push plate 8 is movably connected to the mold frame 1, and the extrusion plate 10 is tightly fitted with the mold body 2. Through the mold frame, push plate, return spring and extrusion plate, when the mold body is inserted into the mold frame, the mold body will push the extrusion plate inward. After the raw material in the pressure groove on the surface of the mold body is cast and formed, the fixing pin is pressed inward. At this time, the extrusion plate pushes the mold body outward by the elastic force of the return spring, realizing automatic material unloading without manual pulling, effectively improving production efficiency.

[0025] Working principle: In use, first move the device to the required position. Select the appropriate mold body 2 according to the different processing shapes. Then press the fixing pin 4 inward. After inserting the mold body 2 into the appropriate position in the mold frame 1, the fixing pin 4 is pushed out by the elastic force of the support spring 3, so that the fixing pin 4 is locked with the mold frame 1. Compared with the traditional bolt fixing method, this utility model makes it more convenient to replace the mold body 2. Then, when the mold body 2 is inserted into the mold frame 1, the mold body 2 will push the extrusion plate 10 inward. After the raw material in the pressure groove 5 on the surface of the mold body 2 is cast, press the fixing pin 4 inward. At this time, the extrusion plate 10 pushes the mold body 2 outward by the elastic force of the return spring 9, realizing automatic material unloading without manual pulling, effectively improving production efficiency. This completes the use of the device. The contents not described in detail in this specification are existing technologies known to those skilled in the art.
