Description

Technical Field

[0001] The invention relates to the technical field of sand casting, in particular to a casting die-cutting process and equipment for a high-precision metal slide. Background Art

[0002] Sand casting refers to a casting method that produces castings in sand molds. Steel, iron and most non-ferrous alloy castings can be obtained by sand casting. Since the molding materials used in sand casting are cheap and easy to obtain, the mold is easy to manufacture, and it can adapt to the single-piece production, batch production and mass production of castings, it has long been the basic process in casting production.

[0003] The basic raw materials for making sand molds are foundry sand and sand binder. The most commonly used foundry sand is siliceous sand. When the high temperature performance of silica sand cannot meet the use requirements, special sands such as zircon sand, chromite sand, and corundum sand are used. In order to make the sand mold and core have a certain strength and not deform or damage during transportation, mold assembly and pouring of liquid metal, it is generally necessary to add a sand binder during casting to bind the loose sand particles together to form sand. The most widely used sand binder is clay, and various drying oils or semi-drying oils, water-soluble silicates or phosphates and various synthetic resins can also be used as sand binders.

[0004] However, after the sand mold is cast, it is usually necessary to further process it, such as cutting and grinding, to make the shape and size of the sand mold more accurate. The existing method is generally to first use a container to complete the casting of the sand mold, and then place the cast sand mold in a cutting device for cutting. This method not only requires the sand mold to be transferred by a conveying device or manpower, resulting in increased production costs and labor intensity, but also has low efficiency.

The terms "vertical", "horizontal", "left", "right" and similar expressions used herein are for illustrative purposes only and are not intended to be the only embodiment.

[0028] See also Figure 1 to Figure 9 In an embodiment of the present invention, a high-precision metal slide casting die-cutting process and equipment includes the following steps: Step 1: Pre-fabricate a container that matches the structural shape, and the inner cavity of the container is roughly the same shape as the metal slide; Step 2: Prepare the required basic raw materials, such as casting sand and sand binder; Step 3: pour the basic raw materials into the casting die-cutting equipment, and use the casting die-cutting equipment to complete the casting and die-cutting of the sand mold; Step 4: After the sand mold die cutting is completed and the casting die cutting equipment is reset, the sand mold is taken out for inspection and cleaning.

[0029] See also Figures 1 to 9 A casting die-cutting device comprises a machine table 1 and a container 2 arranged on the machine table 1, a bracket 3 is slidably arranged on the machine table 1, and a sliding table female mold 4 is movably arranged on the bracket 3 through a vertical reciprocating mechanism; A translation assembly is provided between the platform 1 and the support 3, and the translation assembly can drive the support 3 to move to the top of the container 2; A transmission assembly is also provided between the machine table 1 and the bracket 3, and the transmission assembly is connected to the vertical reciprocating mechanism. When the transmission assembly is running, the vertical reciprocating mechanism will drive the slide table female mold 4 to cut the sand mold in the container 2; The machine platform 1 is provided with a driving mechanism, which is connected to the translation assembly and the transmission assembly respectively, and can alternately drive the translation assembly and the transmission assembly to operate.

[0030] In this scheme, the sand casting can be completed by using the container 2 provided, and the driving mechanism can drive the translation assembly and the transmission assembly to operate alternately. When the translation assembly operates, it can drive the bracket 3 to move and make the slide table female mold 4 located directly above the container 2. During this process, the transmission assembly remains stationary. When the transmission assembly operates, the vertical reciprocating mechanism will drive the slide table female mold 4 to cut the sand mold in the container 2 under the action of the transmission assembly. During this process, the translation assembly remains stationary. In the present application, sand casting is realized through the container 2, and under the action of the driving mechanism, the translation component, the transmission component and the vertical reciprocating mechanism cooperate with each other, so that the slide table female mold 4 is first moved to the top of the container 2, and then the sand mold in the container 2 is cut vertically downward. Compared with the existing technology, the method of integrating the casting and die-cutting of the sand mold not only avoids the transfer of the sand mold, reduces the production cost and labor intensity, but also improves the production efficiency.

[0031] See also Figure 2 , Figure 3 , Figure 4 The translation assembly includes a translation rotating rod 5 and a slide groove 6 horizontally opened along the length direction of the machine 1, and the bottom end of the bracket 3 is located inside the slide groove 6 and slides with each other; One end of the translational rotating rod 5 is horizontally rotatably connected to the inner wall of the slide slot 6, and the other end horizontally penetrates the bracket 3 and the machine platform 1 and extends to the outside of the machine platform 1; The outer wall of the translation rotating rod 5 is provided with a spiral groove 7 , and a ball 8 is rollingly embedded in the interior of the bracket 3 , and the ball 8 is also rollingly embedded in the interior of the spiral groove 7 .

[0032] In this embodiment, since the ball 8 rollingly engaged inside the bracket 3 is also rollingly engaged in the spiral groove 7, and the bottom end of the bracket 3 is located inside the slide groove 6 and slides with each other, when the translation rod 5 rotates, the bracket 3 will slide in the direction of the container 2, thereby moving the slide mold 4 to be directly above the container 2.

[0033] See also Figure 2 , Figure 8 The translation assembly also includes a small gear 9 fixedly disposed on the translation rotating rod 5 and a large gear 10 meshing with the small gear 9 . The large gear 10 is rotatably disposed on the machine platform 1 via a first rotating shaft 11 .

[0034] In this embodiment, since the pinion 9 and the large gear 10 mesh with each other, and the pinion 9 is fixed on the translation rotating rod 5, and the large gear 10 is rotatably arranged on the machine table 1 through the first rotating shaft 11, when the first rotating shaft 11 rotates, the large gear 10 will drive the translation rotating rod 5 to rotate through the pinion 9; Since the diameter of the pinion gear 9 is smaller than that of the large gear 10 , the first rotating shaft 11 can realize the accelerated rotation of the translation rotating rod 5 through the interaction between the large gear 10 and the pinion gear 9 .

[0035] See also Figure 6 , the vertical reciprocating mechanism includes a fixed rod 12 fixedly arranged on the bracket 3 and a spindle 13 horizontally rotatably arranged on the fixed rod 12; A disc 14 is fixedly disposed at one end of the spindle 13, and an eccentric column 15 is eccentrically fixedly disposed on the disc 14; The vertical reciprocating mechanism also includes a lifting rod 16 vertically slidably arranged on the bracket 3, the bottom end of the lifting rod 16 is fixedly connected to the top of the slide female mold 4, and the top end of the lifting rod 16 is rotatably connected to the eccentric column 15 through a connecting rod 17.

[0036] In this embodiment, since the slide mold 4 is vertically slidably set on the bracket 3 through the lifting rod 16, and the lifting rod 16 is rotatably connected with the eccentric column 15 on the disc 14 through the connecting rod 17, when the mandrel 13 on the fixed rod 12 rotates, the disc 14 and the eccentric column 15 will rotate together with the mandrel 13, so that the eccentric column 15 and the connecting rod 17 cooperate with each other to realize the vertical reciprocating movement of the lifting rod 16, so that the slide mold 4 completes the cutting of the sand mold in the container 2.

[0037] See also Figure 6, Fig. 9 The transmission assembly includes a transmission rod 18 and a sleeve 19. The transmission rod 18 is horizontally rotatably arranged on the machine platform 1 through a fixed frame 20. The sleeve 19 is rotatably arranged on the bracket 3 and slidably cooperates with the transmission rod 18. A driving pulley 21 is fixedly disposed on the outer wall of the sleeve 19, and a driven pulley 22 is fixedly disposed on the other end of the spindle 13. The driving pulley 21 and the driven pulley 22 are connected by a transmission belt 23. The outer wall of the transmission rod 18 is fixedly provided with a protruding column 1801 along its length direction, and the inner wall of the sleeve 19 is provided with a groove 1901. The protruding column 1801 is located inside the groove 1901 and slides with each other.

[0038] In this embodiment, since the sleeve 19 is rotatably disposed on the bracket 3 and slidably cooperates with the transmission rod 18, the sleeve 19 will slide on the outer wall of the transmission rod 18 during the sliding process of the bracket 3 toward the container 2. Moreover, since the convex column 1801 fixedly disposed on the outer wall of the transmission rod 18 is located inside the groove 1901 disposed on the inner wall of the sleeve 19 and slidably cooperates with each other, when the transmission rod 18 rotates, the sleeve 19 will rotate along with the transmission rod 18 through the cooperation between the groove 1901 and the convex column 1801. Since the driving pulley 21 fixedly arranged on the outer wall of the sleeve 19 and the driven pulley 22 fixedly arranged on the other end of the spindle 13 are connected through the transmission belt 23, when the sleeve 19 rotates, the driving pulley 21 will rotate synchronously, and at the same time, the spindle 13 will rotate following the driving pulley 21 through the driven pulley 22 and the transmission belt 23; The diameter of the driven pulley 22 is smaller than that of the driving pulley 21 , so the transmission rod 18 can achieve the increased speed rotation of the spindle 13 through the cooperation between the driving pulley 21 and the driven pulley 22 .

[0039] See also Figure 1 , Figure 2 , Figure 8 The driving mechanism includes a driving disk 24, a first driven disk 25 and a second driven disk 26, wherein the driving disk 24 cooperates with the first driven disk 25 and the second driven disk 26 respectively to drive the first driven disk 25 and the second driven disk 26 to rotate alternately; The driving disk 24 is rotatably disposed on the fixing frame 20 via the second rotating shaft 27, the driving disk 24 is rotatably disposed on the first rotating shaft 11, and the second driven disk 26 is rotatably disposed on the transmission rod 18; A motor 28 is fixedly mounted on the machine 1 , and an output end of the motor 28 is fixedly connected to the second rotating shaft 27 . A controller 29 is fixedly mounted on the machine 1 , and the controller 29 is electrically connected to the motor 28 .

[0040] In this embodiment, the driving disk 24, the first driven disk 25 and the second driven disk 26 together form a Maltese cross movement structure, and the first driven disk 25 and the second driven disk 26 can be alternately driven to rotate by the rotation of the driving disk 24; During the rotation of the first driven disk 25 , the first rotating shaft 11 will rotate along with the first driven disk 25 , and the second driven disk 26 remains stationary; During the rotation of the second driven disk 26, the transmission rod 18 will rotate along with the second driven disk 26, and the first driven disk 25 remains stationary; The start and stop of the motor 28 can be controlled by the controller 29. When the motor 28 is running, the output end of the motor 28 will drive the second rotating shaft 27 to rotate, thereby causing the active disk 24 fixed on the second rotating shaft 27 to rotate.
