Description

Technical Field

[0001] This utility model relates to the field of casting equipment technology, and in particular to an interchangeable sand-shooting plate structure. Background Technology

[0002] Currently, in casting production lines, molding machines and core shooters are key equipment for manufacturing sand molds and cores. The ease of use of the sand shooting device, as a crucial component of both the molding and core shooters, is particularly important. Furthermore, the sand shooting device requires adjusting the position of the sand shooting holes according to different molds and necessitates replacing the sand shooting plate. In existing technologies, replacing the sand shooting plate requires lifting it and then securing it with bolts, a cumbersome process. Additionally, sand leakage during plate replacement leads to sand waste and environmental pollution.

[0003] A search revealed that utility model patent document CN219944527U discloses a sand-shooting device with a two-stage sand-shooting plate, including a sand-shooting head, a first-stage sand-shooting plate below the sand-shooting head, and a second-stage sand-shooting plate below the first-stage sand-shooting plate; the sand-shooting head is provided with multiple positioning quick-locking devices around it; the sand-shooting head is installed, disassembled and precisely positioned by the positioning quick-locking devices.

[0004] The aforementioned sand-shooting device requires the combined use of multiple cylinders to complete the fixed connection between the sand-shooting plate and the sand-shooting head. This increases the design and installation costs of the control circuit. Furthermore, the sand-blocking disc in the aforementioned sand-shooting device will, to some extent, obstruct the sand-shooting process and reduce the sand-shooting effect. If the sand-blocking disc is missing, sand leakage will occur when the sand-shooting plate is replaced. Utility Model Content

[0005] The purpose of this invention is to provide an interchangeable sand-shooting plate structure that can reduce the design and installation costs of the control circuit.

[0030] The principles and spirit of this utility model will be explained in detail below with reference to several representative embodiments.

[0031] Please see Figure 1-8 The present invention will now be described in detail with reference to the accompanying drawings and embodiments:

[0032] like Figure 1-2 As shown, an interchangeable sand-shooting plate structure includes a sand-shooting head 1, a primary sand-shooting plate 21 installed below the sand-shooting head 1, and a replaceable movable sand-shooting plate 2 below the primary sand-shooting plate 21. The sand-shooting head 1 is used to store sand for core making. Several blocking components 4 are installed between the sand holes of the primary sand-shooting plate 21 and the movable sand-shooting plate 2 to block the sand. Six locking components 3 are evenly arranged on the four outer sides of the sand-shooting head 1 near the lower end. The locking components 3 can realize the quick installation and disassembly of the movable sand-shooting plate 2, improving processing efficiency. The position of the sand-shooting hole of the movable sand-shooting plate 2 can be adjusted according to the needs of the mold, and there can be several movable sand-shooting plates 2, which facilitates the replacement of the movable sand-shooting plate 2 and improves core making efficiency.

[0033] like Figure 2 As shown, the lower end face of the sand-shooting head 1 is provided with an installation groove 11. The first-stage sand-shooting plate 21 is fixedly installed in the installation groove 11 by bolts. The upper surface of the movable sand-shooting plate 2 near the side is provided with six locking heads 22 at positions corresponding to the locking assembly 3. The locking heads 22 are fixed to the movable sand-shooting plate 2 by bolts.

[0034] like Figure 3-5 As shown, the locking assembly 3 includes a fixed block 31, a sliding block 32 and a fixed frame 34 arranged sequentially from top to bottom. The fixed block 31 and the fixed frame 34 are both fixedly arranged on the outer side of the sand-shooting head 1, and the sliding block 32 is slidably arranged on the outer side of the sand-shooting head 1.

[0035] like Figure 3-5 As shown, T-shaped locking blocks 35 are symmetrically arranged on both sides of the fixed frame 34. A guide groove 12 is opened on the outer side of the shot head 1 at the position corresponding to the locking block 35. A part of the locking block 35 slides in the guide groove 12 to ensure the stability of the locking block 35 sliding laterally. A slider 351 is fixedly arranged on the outer side of the locking block 35 relative to the fixed frame 34. The slider 351 is slidably arranged in the fixed frame 34. A spring 352 is fixedly connected between the two sliders 351. The spring 352 is used to reset the locking block 35 after it has moved.

[0036] like Figure 3-5As shown, the locking head 22 has an inverted T-shaped slot 221 that is adapted to the locking block 35. Rubber pads 222 are fixedly installed on both sides of the vertical inner wall of the slot 221. The rubber pads 222 are used to enhance the connection between the locking block 35 and the locking head 22. An inclined surface is provided at the opening of the slot 221 at the upper end of the locking head 22. The inclined surface is adapted to the inclined surface of the locking block 35 to facilitate the locking block 35 to enter the slot 221.

[0037] like Figure 3-5 As shown, a hinge plate 36 is provided between the locking block 35 and the sliding block 32. The two ends of the hinge plate 36 are respectively hinged to the locking block 35 and the sliding block 32. When the locking block 35 enters the lower half of the slot 221, the angle of the hinge plates 36 on both sides changes due to the descent of the sliding block 32, pushing the locking blocks 35 on both sides to slide outwards, so that the locking block 35 contacts the rubber pad 222. At this time, the locking head 22 and the sand-shooting head 1 are fixedly connected and there will be no loosening.

[0038] like Figure 3-5 As shown, a bolt 33 is provided above the sliding block 32. The surface of the bolt 33 is divided into three parts: the upper surface is threaded, the middle part is a smooth axial surface, and the lower surface is threaded. The bolt 33 passes through the fixing block 31, and the threaded part can be threadedly engaged with the fixing block 31. The smooth axial surface part can slide freely, and the lower end of the bolt 33 is rotated with the sliding block 32.

[0039] In this embodiment, after the primary sand-shooting plate 21 is installed, the movable sand-shooting plate 2 is assembled with the sand-shooting head 1, causing the locking head 22 to push the two side sliders 351 to slide relative to each other. At this time, the smooth axial surface of the bolt 33 slides up and down on the fixed block 31. When the locking block 35 enters the slot 221 of the locking head 22, the bolt 33 is restored to its original position by the spring 352. At this time, the locking block 35 provides support for the locking head 22, and the movable sand-shooting plate 2 no longer needs to be supported. Then, the bolt 33 is tightened so that the upper thread of the bolt 33 engages with the fixed block 31. During this process, the bolt 33 moves down, causing the two side locking blocks 35 to slide outward. When the locking blocks 35 move and contact the rubber pad 222, they compress the rubber pad 222. At this time, the fixed engagement between the movable sand-shooting plate 2 and the sand-shooting head 1 is completed. The installation process is simple and quick, does not require the participation of electrical components, and reduces the design and installation costs of the control circuit.

[0040] Furthermore, when it is necessary to disassemble and replace the movable sand-shooting plate 2, the bolt 33 is turned in the opposite direction until the upper thread of the bolt 33 engages with the fixing block 31. At this time, the locking blocks 35 on both sides are disconnected from the locking head 22, and the movable sand-shooting plate 2 can be easily removed for replacement.

[0041] like Figure 6-8As shown, the plugging assembly 4 includes a support member 41 and a sealing ring 43. The upper cylindrical part of the support member 41 is fitted into the sand hole of the primary sand-shooting plate 21, and the upper cylindrical part of the sealing ring 43 is fitted into the sand hole of the movable sand-shooting plate 2.

[0042] like Figure 6-8 As shown, the lower end face of the support member 41 is provided with a cross-shaped sliding groove 411, and four top blocks 42 are slidably installed in the sliding groove 411. The outer side of each top block 42 is fixedly connected to the inner wall of the sliding groove 411 with a spring 421 to facilitate the reset of the top block 42. When the top blocks 42 are closed, they can seal the inner cavity of the cylinder. A cover plate 412 is installed below the support member 41 to seal the top blocks 42 and facilitate the sliding of the top blocks 42.

[0043] like Figure 6-8 As shown, an ejector 431 is fixedly provided on the upper end face of the sealing ring 43, and an arc-shaped surface is provided on the lower surface of the top block 42. The arc-shaped surface is adapted to the ejector 431, and a plug 432 can be arranged at the lower end of the sealing ring 43 where sand discharge is not required.

[0044] In this embodiment, after the first-stage sand-shooting plate 21 is installed, the inner cavity of the cylindrical support member 41 is closed. When the movable sand-shooting plate 2 is installed, the ejector 431 at the upper end of the sealing ring 43 will squeeze the top block 42, causing the ejector 431 to slide in the sliding groove 411, releasing the seal on the inner cavity of the support member 41, allowing sand to be discharged. When the movable sand-shooting plate 2 is replaced, after the movable sand-shooting plate 2 is separated from the first-stage sand-shooting plate 21, the top block 42 is reset by the spring 421, which can completely prevent the sand above the first-stage sand-shooting plate 21 from falling, and no leakage will occur.
