[0027] like Figures 1-5As shown, this utility model provides a casting mold for a precision batching and mixing sand machine, including: a mold body 1, on which a fixing mechanism 2 is provided;

[0028] The fixing mechanism 2 includes two clamping plates 201, two slots 208, and two positioning slots 210. A rectangular plate 202 is arranged between the two clamping plates 201. Two limiting rods 203 are fixed on both sides of the rectangular plate 202. A cylindrical hole 204 is opened on one side of the rectangular plate 202. A round rod 205 is rotatably connected to the inside of the cylindrical hole 204 through a bearing. Both ends of the round rod 205 are fixed with screws 206. A turntable 207 is installed at one end of one of the screws 206. Two symmetrical positioning blocks 209 are fixed to the bottom of the rectangular plate 202. The two clamping plates 201 are arranged symmetrically, and the two clamping... The clamping ends of plate 201 are respectively located inside two slots 208. The two sides of rectangular plate 202 are in contact with the opposite sides of the two clamping plates 201. The four limiting rods 203 are divided into two groups. The opposite ends of the two groups of limiting rods 203 respectively movably pass through the opposite sides of the two clamping plates 201. The opposite sides of the two groups of limiting rods 203 are respectively fixed to the two sides of rectangular plate 202. The opposite ends of the two screws 206 respectively thread through the opposite sides of the two clamping plates 201. The two positioning blocks 209 are respectively located inside the two positioning slots 210. The mold body 1 includes a lower frame 101 and two... The opposite sides of the clamping plates 201 contact the two sides of the lower frame 101, and the upper frame 102 is placed on the top of the lower frame 101. The opposite sides of the two clamping plates 201 contact the two sides of the upper frame 102, and two slots 208 are symmetrically opened at the bottom of the lower frame 101 near the edge. Two positioning slots 210 are symmetrically opened at the top of the upper frame 102. An upper mold 103 is provided inside the upper frame 102, and the top of the upper mold 103 contacts the bottom of the rectangular plate 202. The top of the upper frame 102 contacts the bottom of the rectangular plate 202. The lower frame 101... The lower mold 104 is provided inside. The bottom of the upper mold 103 is in contact with the top of the lower mold 104. Cylindrical blocks 105 are fixed at the four bottom corners of the lower frame 101. U-shaped rings 106 are fixed on the front surface of the lower frame 101, the rear surface of the lower frame 101, the front surface of the upper frame 102, and the rear surface of the upper frame 102. A feed hole 107 is provided on the lower side of the upper mold 103. Rectangular blocks 108 are fixed at the four top corners of the lower frame 101. Rectangular grooves 109 are provided at the four bottom corners of the upper frame 102. Each rectangular block 108 is located inside each rectangular groove 109.

[0029] The desired effect is as follows: when casting is required using a precision batching and mixing machine to create molds, the precision batching and mixing machine first produces molding sand that meets the requirements. Then, using the produced molding sand, the upper frame 102, and the prepared mold cavity, the upper mold 103 is manufactured. Next, the upper mold 103 is baked and shaped. Then, using the produced molding sand, the lower frame 101, and the prepared mold cavity, the lower mold 104 is manufactured. The lower mold 104 is also baked and shaped. When everything is ready, two U-shaped rings 106, four cylindrical blocks 105, and... The lower mold 104 is moved by the cooperation of the lower frame 101 and then placed stably on the horizontal ground. Next, the upper mold 103 is moved by the cooperation of the other two U-shaped rings 106 and the upper frame 102. Then, the upper mold 103 and the lower mold 104 are quickly and accurately aligned by the cooperation of multiple rectangular slots 109 and multiple rectangular blocks 108. Then, the rectangular plate 202 is moved, which will drive the entire fixing mechanism 2 (except for the two slots 208 and the two positioning slots 210) to move. After that, multiple positioning blocks 209 and multiple positioning slots 210 are used to move the entire fixing mechanism 2. With the cooperation of 0, the rectangular plate 202 is quickly and accurately placed on the upper frame 102. When the rectangular plate 202 is placed, the upper frame 102 and the lower frame 101 are exactly between the two clamping plates 201. Then, the turntable 207 is rotated. At this time, the rotating turntable 207, with the cooperation of the cylindrical hole 204, bearing, two screws 206, two sets of limit rods 203 and round rod 205, causes the two clamping plates 201 to move towards each other. When the locking ends of the two clamping plates 201 move into the two locking slots 208 respectively, the turntable 207 just stops rotating. At this time, the upper mold 103 and the lower mold 104 are ready to be locked. It can be tightly fixed together, and then the molten metal injected into the feed hole 107 is guided to the space between the upper mold 103 and the lower mold 104 using the cooperation of the feed hole 107. When an appropriate amount of molten metal is injected into the space between the upper mold 103 and the lower mold 104, the injection of molten metal into the feed hole 107 is stopped. Then the casting mold is allowed to cool for a period of time. Then the above operation steps are repeated in reverse to separate the upper mold 103 and the lower mold 104, and the required casting can be obtained. The operation is simple and does not require the operator to lift heavy objects repeatedly or frequently, thus ensuring the production efficiency of the casting.

[0030] Working principle: When casting is required using a precision batching and mixing machine to create molds, the machine first produces molding sand that meets the requirements. Then, using the produced molding sand, the upper frame 102, and the prepared mold cavity, the upper mold 103 is manufactured. The upper mold 103 is then baked and shaped. Next, using the produced molding sand, the lower frame 101, and the prepared mold cavity, the lower mold 104 is manufactured. The lower mold 104 is also baked and shaped. When everything is ready, two U-shaped rings 106 and four circular... The engagement of the column block 105 and the lower frame 101 moves the lower mold 104 to a stable position on a horizontal surface. Then, using the engagement of the two U-shaped rings 106 and the upper frame 102, the upper mold 103 is moved. Next, using the engagement of multiple rectangular slots 109 and multiple rectangular blocks 108, the upper mold 103 and the lower mold 104 are quickly and accurately aligned. Then, the rectangular plate 202 is moved, causing the entire fixing mechanism 2 (excluding the two slots 208 and the two positioning slots 210) to move. Finally, using... The cooperation of multiple positioning blocks 209 and multiple positioning slots 210 allows the rectangular plate 202 to be placed quickly and accurately on the upper frame 102. When the rectangular plate 202 is placed, the upper frame 102 and the lower frame 101 are exactly between the two clamping plates 201. Then, the turntable 207 is rotated. At this time, the rotating turntable 207, with the cooperation of the cylindrical hole 204, bearing, two screws 206, two sets of limit rods 203 and round rod 205, causes the two clamping plates 201 to move towards each other. When the locking ends of the two clamping plates 201 move into the two locking slots 208 respectively, the turntable... When 207 stops rotating, the upper mold 103 and the lower mold 104 can be tightly fixed together. Then, using the feed hole 107, the molten metal injected into the feed hole 107 is guided to the space between the upper mold 103 and the lower mold 104. When a suitable amount of molten metal is injected into the space between the upper mold 103 and the lower mold 104, the injection of molten metal into the feed hole 107 is stopped. Then, the casting mold is allowed to cool for a period of time. Then, the above operation steps are repeated in reverse to separate the upper mold 103 and the lower mold 104, and the desired casting can be obtained.

[0031] Among them, the two screws 206 and the round rod 205 can form a bidirectional threaded rod.

[0032] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model in any other way. Any person skilled in the art may make changes or modifications to the above-disclosed technical content to create equivalent embodiments for application in other fields. However, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of the present utility model without departing from the technical solution of the present utility model shall still fall within the protection scope of the present utility model.
