Description

Technical Field

[0001] This utility model relates to the field of die-casting mold technology, specifically a mold with a replaceable mold core. Background Technology

[0002] Die casting molds are tools used to cast metal parts, specifically for completing the die casting process on a specialized die casting and forging machine. The basic die casting process involves molten metal being poured into the mold cavity at low or high speed. The mold has movable cavity surfaces, which are pressurized and forged as the molten metal cools, eliminating shrinkage cavities and porosity defects in the blank and achieving a forged, fragmented grain structure. This significantly improves the overall mechanical properties of the blank.

[0003] According to a die-casting mold with replaceable mold core disclosed in the above application (Announcement No.: CN220782205U), the design of the support structure enables the device to install and fix the stamping structure, thereby completing the stamping. The design of the clamping structure enables the inner side of the die base to clamp the upper end of the mold core, thereby ensuring the stamping quality. The design of the clamping structure enables the die base of the device to install and fix the mold core, thereby ensuring a tight connection between the mold core and the die base.

[0004] The aforementioned die-casting mold requires a clamping structure and a mounting structure to fix the mold core during use. The clamping structure and mounting structure are complex, which increases the cost of using the mold. Utility Model Content

[0005] The purpose of this invention is to provide a mold with a replaceable mold core to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a mold with a replaceable mold core, comprising a mold body, an installation groove on the surface of the mold body, a mold core body placed inside the installation groove, dovetail blocks fixedly connected to four sets of side walls of the mold core body, four sets of positioning components arranged inside the installation groove, each positioning component including a mounting base, a crossbar fixedly connected to the side wall of the mounting base, the crossbar penetrating and slidably connected to the side wall of the mold body, a dovetail groove on the side wall of the mounting base, and a dovetail block inserted into the dovetail groove.

[0007] Preferably, the bottom surface of the mounting groove is provided with a sliding groove, and a support assembly is provided inside the sliding groove. The support assembly includes two sets of sliders, which are slidably connected to the inner wall of the sliding groove. An inclined plate is hinged to the surface of the slider, and a support plate is hinged to the top of the inclined plate.

[0008] Preferably, a guide rod is provided on the bottom surface of the support plate, and the guide rod passes through and is slidably connected to the bottom of the mold body.

[0009] Preferably, the two sets of sliders are connected by a bidirectional threaded rod, which passes through and is rotatably connected to the side wall of the mold body.

[0010] Preferably, a rotating wheel is fixedly connected to the end of the bidirectional threaded rod.

[0011] Preferably, the crossbars are arranged symmetrically in two sets with the center line of the mounting base as the axis of symmetry.

[0012] Compared with the prior art, this utility model provides a mold with a replaceable mold core, which has the following features:

[0013] Beneficial effects:

[0014] 1. This replaceable mold core mold uses a dovetail groove to connect with the dovetail block of the mold core, forming a concave-convex positioning structure. At the same time, four sets of positioning components cooperate with each other to fix the main body of the mold core, preventing the main body of the mold core from moving. The structure is simple and reduces the cost of using the mold.

[0015] 2. The replaceable mold core is driven by a rotating wheel to rotate a bidirectional threaded rod, causing the two sets of sliders connected to it to move towards each other. This reduces the tilt angle of the inclined plate, allowing the support plate to rise steadily under the guidance of the guide rod, thus pushing the mold core body out of the mounting slot for easy removal and replacement of the mold core body.

[0021] like Figures 1-4As shown, this utility model provides a technical solution: a mold with a replaceable mold core, including a mold body 1, a mounting groove 2 on the surface of the mold body 1, a mold core body 3 placed inside the mounting groove 2, dovetail blocks 31 fixedly connected to each of the four side walls of the mold core body 3, and four sets of positioning components 4 arranged inside the mounting groove 2. The mounting groove 2 is used to accommodate the mold core body 3, and the mold core body 3 is positioned and fixed horizontally by cooperating with the four sets of positioning components 4 in the mounting groove 2 through the dovetail blocks 31. The positioning component 4 includes a mounting base 41, with a crossbar 42 fixedly connected to the side wall of the mounting base 41. Two sets of crossbars 42 are symmetrically arranged about the centerline of the mounting base 41. The crossbars 42 provide support and sliding guidance for the mounting base 41, allowing for positional adjustment so that the mounting base 41 can be positioned close to the side wall of the mold core body 3 of different sizes. The crossbars 42 pass through and are slidably connected to the side wall of the mold body 1. A dovetail groove 43 is formed on the side wall of the mounting base 41, and a dovetail block 31 is inserted into the dovetail groove 43. The dovetail groove 43 and the dovetail block 31 of the mold core interlock to form a convex-concave positioning structure. Simultaneously, the four sets of positioning components 4 cooperate to fix the mold core body 3, preventing movement of the mold core body 3. The structure is simple, reducing the cost of using the mold.

[0022] The bottom surface of the mounting groove 2 is provided with a sliding groove 5. A support assembly 6 is installed inside the sliding groove 5. The support assembly 6 includes two sets of sliders 61, which are slidably connected to the inner wall of the sliding groove 5. The two sets of sliders 61 are threaded together by a bidirectional threaded rod 62, which passes through and is rotatably connected to the side wall of the mold body 1. A rotating wheel 63 is fixedly connected to the end of the bidirectional threaded rod 62, driving the bidirectional threaded rod 62 to rotate, causing the two sets of sliders 61 threaded together to move towards each other or away from each other, thereby adjusting the distance between the two sets of sliders 61. An inclined plate 64 is hinged to the surface of the slider 61, and a support plate 65 is hinged to the top of the inclined plate 64. A guide rod 66 is provided on the bottom surface of the support plate 65, which passes through and is slidably connected to the bottom of the mold body 1. By moving the two sets of sliders 61 in opposite directions, the tilt angle of the inclined plate 64 is reduced, and the support plate 65 rises steadily under the guidance of the guide rod 66, thereby pushing the mold core body 3 inside the mounting groove 2 out of the mounting groove 2, thus facilitating the removal and replacement of the mold core body 3.

[0023] In this utility model, during use, the crossbar 42 allows the mounting base 41 to be adjusted in position, so that the mounting base 41 is close to the side wall of the mold core body 3. It is inserted into the dovetail block 31 of the mold core through the dovetail groove 43 to form a positioning structure with concave and convex fit. At the same time, the four sets of positioning components 4 cooperate with each other to fix the mold core body 3 and prevent the mold core body 3 from moving. The structure is simple and reduces the use cost of the mold.

[0024] The rotating wheel 63 drives the bidirectional threaded rod 62 to rotate, causing the two sets of sliders 61 connected to it to move towards each other. This adjusts the distance between the two sets of sliders 61, thereby reducing the tilt angle of the inclined plate 64. Under the guidance of the guide rod 66, the support plate 65 rises steadily, thus pushing the mold core body 3 inside the mounting groove 2 out of the mounting groove 2, making it easier to remove and replace the mold core body 3.

[0025] The present invention has been described in detail above. However, modifications or improvements can be made to it, which will be obvious to those skilled in the art. Therefore, any modifications or improvements that do not depart from the spirit of the present invention are within the protection scope of the present invention.
