[0002] In the foundry industry, the core shooter is a key piece of equipment, and its efficient and precise core-making performance plays a decisive role in the quality of castings and production efficiency. Sandblasting, as an important part of the core shooter production process, can effectively remove impurities and oxide scale from the mold surface, ensuring the quality of the mold surface and thus improving the accuracy of sand core forming and the quality of castings.
[0003] Patent searches revealed that an existing patent, CN221870193U, entitled "A Core Shooter for Casting," features a flipping and blowing mechanism that facilitates the cleaning of residual sand from the mold cavity, offering certain advantages. However, the sandblasting machine in this patent can only move linearly in the vertical direction and lacks lateral translation capability. This limitation makes it difficult for the sandblasting machine to adapt to new molds if the lateral position of the sand injection holes changes, resulting in poor environmental adaptability. Therefore, this patent provides an alternative core shooter for casting to solve the aforementioned technical problems. Utility Model Content
[0004] In view of the shortcomings of the prior art described above, the purpose of this utility model is to provide a casting core shooter to solve the problem that the existing core shooter and sandblasting machine adopt a fixed structure, which makes it inconvenient to adjust the position of the sandblasting machine according to different molds to adapt to new molds, resulting in poor environmental adaptability of the equipment.
[0005] To achieve the above objectives, this utility model provides the following technical solution:
[0006] A core shooter for casting includes a base with a cavity on its upper surface. A mold opening and closing device is fixedly installed on the left side of the upper surface of the base, and a mold is detachably installed inside the mold opening and closing device. Support frames are fixedly installed on both the front and rear left surfaces of the base. An L-shaped carrier plate is fixedly installed between the upper surfaces of the two support frames. An opening is formed on the upper surface of the L-shaped carrier plate. A hydraulic telescopic rod A is fixedly installed on the inner surface of the L-shaped carrier plate. A splash guard is fixedly installed on the right surface of the hydraulic telescopic rod A. The splash guard is laterally slidably installed below the L-shaped carrier plate, and an inverted U-shaped frame is fixedly installed inside the splash guard. A hydraulic telescopic rod B is fixedly installed through the inverted U-shaped frame. A sandblasting machine is fixedly installed on the lower surface of the hydraulic telescopic rod B. The sandblasting machine is located inside the splash guard, and the sandblasting nozzle of the sandblasting machine is located above the injection port of the mold.
[0007] In the above technical solution, two track grooves are symmetrically opened on the upper surface of the L-shaped carrier plate, and a traveling platform is rolled between the two track grooves. A sand tank is inserted into the traveling platform, and a sand guide hose is fixedly connected between the discharge end of the sand tank and the feed end of the sandblasting machine.
[0008] In the above technical solution, a folding plate is fixedly installed between the walking platform and the inverted U-shaped frame.
[0009] In the above technical solution, the mold opening and closing device includes a mold connecting plate A and a fixing plate. Both the mold connecting plate A and the fixing plate are fixedly installed on the upper surface of the base. Two guide rods are fixedly installed between the mold connecting plate A and the fixing plate. A mold connecting plate B is slidably installed between the two guide rods. A hydraulic telescopic rod C is fixedly installed between the right surface of the mold connecting plate B and the fixing plate. Mold A and mold B are respectively fixedly installed on the opposite surfaces of the mold connecting plate A and the mold connecting plate B by long screws.
[0010] In the above technical solution, the lower surface of the splash guard is attached to the upper surface of the mold A.
[0011] In the above technical solution, a drawer groove is provided on the left surface of the base. The drawer groove is connected to the cavity of the base, and a material collection box is inserted and installed in the drawer groove. The right surface of the material collection box is attached to the left surface of the mold connecting plate A.
[0012] In the above technical solution, two L-shaped track plates are fixedly installed on the lower surface of the L-shaped carrier plate, and two hanging rods are fixedly installed on the front and rear surfaces of the splash cover. Rollers are rotatably installed on the side of the hanging rods near the inverted U-shaped frame, and the rollers are rolled on the corresponding L-shaped track plates.
[0013] The core shooting machine for casting of this utility model has the following advantages compared with the prior art:
[0014] I. This utility model uses an inverted U-shaped frame to fix the hydraulic telescopic rod B and the sandblasting machine to the splash guard. It can use the hydraulic telescopic rod A to move the splash guard while adjusting the sand injection position of the sandblasting machine into the mold laterally, so as to adapt to the use of molds of different sizes and increase the overall applicability of the core shooting machine.
[0015] II. This utility model sets track grooves on an L-shaped carrier plate, uses two track grooves to set a walking platform with a sand tank on the L-shaped carrier plate, and fixes a folding plate between the walking platform and the inverted U-shaped frame.

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. 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] In this embodiment, front, back, left, right, top, and bottom are... Figure 1 Describe the reference plane. See [link / reference] Figures 1-5 This utility model provides a technical solution:
[0024] A core shooter for casting includes a base 1 with a cavity on its upper surface. A mold opening and closing device 2 is fixedly installed on the left side of the upper surface of the base 1. A mold is detachably installed inside the mold opening and closing device 2. Support frames 3 are fixedly installed on the front and rear left surfaces of the base 1. An L-shaped carrier plate 31 is fixedly installed between the upper surfaces of the two support frames 3. An opening 311 is opened on the upper surface of the L-shaped carrier plate 31. A hydraulic telescopic rod A33 is fixedly installed on the inner surface of the L-shaped carrier plate 31. A splash guard 4 is fixedly installed on the right surface of the hydraulic telescopic rod A33. The splash guard 4 is laterally slidably installed below the L-shaped carrier plate 31. The extension and retraction of the hydraulic telescopic rod A33 can drive the splash guard 4 to move horizontally left and right to adjust its position.
[0025] An inverted U-shaped frame 41 is fixedly installed inside the splash guard 4. A hydraulic telescopic rod B5 is fixedly installed through the inverted U-shaped frame 41. The hydraulic telescopic rod B5 is located inside the opening 311. A sandblasting machine 6 is fixedly installed on the lower surface of the hydraulic telescopic rod B5. The sandblasting machine 6 is located inside the splash guard 4. By moving the position of the splash guard 4, the sandblasting nozzle of the sandblasting machine 6 can be positioned above the injection port of the mold. By extending the hydraulic telescopic rod B5, the sandblasting nozzle of the sandblasting machine 6 can be moved down to align with the sand injection port of the mold for injection.
[0026] Combination Figure 1 and Figure 5 As shown, two L-shaped track plates 32 are fixedly installed on the lower surface of the L-shaped carrier plate 31, and two hanging rods 42 are fixedly installed on the front and rear surfaces of the splash cover 4. Rollers 421 are rotatably installed on the side of the hanging rods 42 near the inverted U-shaped frame 41. The rollers 421 are rolled on the corresponding L-shaped track plates 32. The splash cover 4 is laterally slidably installed under the L-shaped carrier plate 31 through the cooperation of the hanging rods 42, rollers 421 and L-shaped track plates 32.
[0027] like Figure 2 As shown, two track grooves 312 are symmetrically opened on the upper surface of the L-shaped carrier plate 31. A traveling platform 7 with movable wheels at the bottom is rolled between the two track grooves 312. The movable wheels of the traveling platform 7 are respectively located in the corresponding track grooves 312. A sand tank 8 is inserted into the traveling platform 7. A sand guide hose 61 is fixedly connected between the discharge end of the sand tank 8 and the feed end of the sandblasting machine 6. When the sandblasting machine 6 is started, the sand in the sand tank 8 enters the sandblasting machine 6 through the sand guide hose 61.
[0028] During the position adjustment of the sandblasting machine 6, in order to ensure that the sand tank 8 can move accordingly and to prevent the sand guide hose 61 from shortening its service life and reducing its performance due to excessive bending, a folding plate 71 needs to be fixedly installed between the walking platform 7 and the inverted U-shaped frame 41. In this way, when the splash guard 4 moves the sandblasting machine 6 to change position, the inverted U-shaped frame 41 and the folding plate 71 can move the walking platform 7 synchronously, effectively avoiding the problem of bending of the sand guide hose 61 caused by the lateral movement of the sandblasting machine 6, thereby extending the service life of the sand guide hose 61.
[0029] like Figure 1 As shown, the mold opening and closing device 2 includes a mold connecting plate A21 and a fixing plate 22. Both the mold connecting plate A21 and the fixing plate 22 are fixedly installed on the upper surface of the base 1. Two guide rods 23 are fixedly installed between the mold connecting plate A21 and the fixing plate 22. A mold connecting plate B24 is slidably installed between the two guide rods 23. A hydraulic telescopic rod C25 is fixedly installed between the right surface of the mold connecting plate B24 and the fixing plate 22. Mold A and mold B24 are respectively fixedly installed on the opposite surfaces of the mold connecting plate A21 and the mold connecting plate B24 by long screws. Mold B, with its hydraulic telescopic rod C25 extending and retracting, can move left and right via the mold connecting plate B24, thereby causing mold B to engage or disengage with mold A. When replacing mold A and mold B, the corresponding mold can be disassembled by unscrewing the long screw. When replacing and installing mold A and mold B, the upper surfaces of both need to be flush with the upper surface of the mold connecting plate A21 to ensure that after mold A and mold B are engaged, the lower surface of the splash guard 4 can fit against the upper surfaces of mold A and mold B, ensuring the anti-splashing effect when injecting sand into the mold.
[0030] After the sand is injected into the mold by the sandblasting machine 6, residual sand will remain on the top of the mold. When the splash guard 4 moves to the left to reset, the residual sand can be scraped off to the left along the upper surface of the mold. To facilitate the collection of residual sand, a drawer slot 11 is provided on the left surface of the base 1. The drawer slot 11 is connected to the cavity of the base 1, and a collection box 12 is inserted into the drawer slot 11. The right surface of the collection box 12 is attached to the left surface of the mold connecting plate A21. The residual sand falling from the mold falls directly into the collection box 12 for collection. After subsequent screening, it can be recycled and reused.
[0031] Finally, as Figure 1 As shown, a comprehensive controller 9 is fixedly installed on the front surface of the support frame 3. This controller 9 adopts a modular design, integrating a programmable logic controller (PLC) and a high-precision sensor signal processing unit, possessing data acquisition, logic operation, and instruction output functions. Through dedicated control cables, the comprehensive controller 9 is electrically connected to the control signal input terminals of the sandblasting machine 6, hydraulic telescopic rods A33, B5, and C25, forming a closed-loop control system. Operators can preset the extension stroke, movement speed, and start / stop sequence of each hydraulic telescopic rod through the human-machine interface of the comprehensive controller 9, monitor the equipment's operating status in real time, and quickly respond to and diagnose abnormal situations. The comprehensive controller 9 can also control the start and stop of the sandblasting machine 6.
[0032] Working Principle: In use, molds A and B are fixed to mold connecting plate A21 and mold connecting plate B24 respectively using long bolts. Then, the integrated controller 9 drives the hydraulic telescopic rod C25 to extend, moving mold B towards mold A, so that the two are engaged to form a mold platform. Next, according to the preset instructions of the integrated controller 9, the hydraulic telescopic rod A33 extends a certain distance, causing the splash guard 4, inverted U-shaped frame 41, hydraulic telescopic rod B5, and sandblasting machine 6 to move to the right, moving the sandblasting nozzle of the sandblasting machine 6 to the sand injection port position of the mold platform. Then, the integrated controller 9 drives the hydraulic telescopic rod B5 to extend, causing the sandblasting nozzle of the sandblasting machine 6 to move downwards and connect with the sand injection port of the mold platform. Finally, sandblasting is started. The machine 6 injects sand into the mold as a whole. Under high pressure, the sand is shaped inside the mold. Then, the hydraulic telescopic rod A33 is driven to retract, which moves the splash guard 4 to the left to reset. During the reset, the residual sand above the mold is scraped to the left and finally falls into the collection box 12 for collection. Finally, the hydraulic telescopic rod C25 is driven to retract, which drives the mold B to separate from the mold A through the mold connecting plate B24. At this time, the formed product can be manually removed from the mold. Compared with the existing technology, the overall design of this core shooting machine can adjust the sand injection position of the sand shooting machine 6 into the mold by moving the splash guard 4 with the hydraulic telescopic rod A33 when changing to a larger mold, so as to adapt to the use of molds of different sizes and increase the overall applicability of the core shooting machine.
