Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0023] Please see Figures 1-5 In this embodiment of the utility model, a metal casting forming mold with quick-change components includes a support (1), the support (1) is a rectangular steel structure with a mold frame middle plate (2) fixedly installed on its top by bolts, and a base plate (5) is welded and fixed to one end of the support (1) away from the mold frame middle plate (2).
[0024] The mold frame middle plate (2) is connected to the upper mold frame plate (3) by means of positioning pins and bolts at the end away from the support (1). An injection tube (4) is installed through the upper center of the upper mold frame plate (3), with an inner diameter adapted to the flow rate requirement of molten metal. A material picking groove (6) is opened along the length direction at the upper part of the mold frame middle plate (2), with a depth penetrating 1 / 2 of the thickness of the mold frame middle plate (2).
[0025] A circular groove (9) is coaxially provided on one side of the material feeding groove (6). The inner diameter of the circular groove (9) is in clearance fit with the outer diameter of the mold core (7). An arc buckle (10) is installed at the groove opening of the circular groove (9) by a hinge. Its free end is fixed to the mold frame intermediate plate (2) by a locking bolt.
[0026] A mold core (7) is embedded in the inner side of the circular groove (9);
[0027] The top of the intermediate plate (2) of the mold frame is equipped with pins (8) around the top. The pins (8) are made of 40Cr alloy structural steel. Their bottoms penetrate the upper part of the intermediate plate (2) of the mold frame and are threadedly connected to the upper part of the support (1). The upper part of the mold core (7) is connected to the mold (13) through the positioning key. The cavity size of the mold (13) is adapted to the target casting specification. The upper part of the mold (13) is bolted to the mold cavity box (11). The upper surface of the mold cavity box (11) is vertically connected to the injection pipe (12). The injection pipe (12) and the injection tube (4) are coaxially arranged and connected by a flange seal.
[0028] A connecting pipe (14) is welded and installed at the upper center of the mold (13). The inner diameter of the connecting pipe (14) is the same as that of the injection pipe (12). The connecting pipe (14) is connected to the injection pipe (12). A top column (20) is slidably installed at the bottom of the connecting pipe (14). A return spring is connected to the top of the top column (20).
[0029] The lower part of the mold core (7) is provided with a lower mold base (15) that is bolted to the mold (13). 3-4 support rods (16) are evenly welded and fixed to the bottom of the lower mold base (15). The bottom of the support rods (16) abuts against the top of the support base (1).
[0030] Cooling pipes (17) are embedded in the inner frame of the intermediate plate (2) of the mold frame. The cooling pipes (17) adopt a spiral layout and the distance between them and the outer wall of the mold (13) is 5-8mm.
[0031] A bottom sealing pipe (18) is welded to one end of the cooling pipe (17). The bottom sealing pipe (18) has a three-way structure, with one end connected to the cooling pipe (17), one end connected to the liquid inlet pipe, and one end connected to the liquid outlet pipe.

[0033] The top of the bottom sealing tube (18) abuts against the bottom of the mold (13) for support.
[0034] The working principle of this utility model is as follows:
[0035] Production process: Molten metal enters the cavity of mold (13) through injection pipe (4), injection pipe (12), and connecting pipe (14);
[0036] At the same time, the cooling system is started, and the cooling medium enters the cooling pipe (17) through the bottom sealing pipe (18) to cool the mold (13). After the casting solidifies, the external ejection mechanism pushes the ejector column (20) to eject the casting. The casting is taken out through the material pick-up slot (6), and the ejector column (20) returns to its original position under the action of the reset spring, completing a single production.
[0037] When it is necessary to change the casting specifications, first disassemble the flange connection between the injection pipe (4) and the injection pipe (12); open the arc buckle (10), take out the old mold core (7) and the associated mold (13), mold cavity box (11) and other components; put the mold core equipped with the new specification mold into the round groove (9), lock the arc buckle (10), reconnect the melt channel, and production can be resumed. The entire replacement process takes less than 15 minutes.
[0038] Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
