Description

Technical Field

[0001] This application relates to the field of mold manufacturing technology, specifically to a tooling for manufacturing a fire-proof groove. Background Technology

[0002] Ductile iron, a high-strength cast iron material developed in the 1950s, boasts comprehensive properties approaching those of steel. For parts requiring high strength, toughness, and wear resistance, ductile iron has rapidly become the second most important cast iron material after gray cast iron. Ductile iron is produced by spheroidizing and inoculating to obtain spheroidal graphite, effectively improving the mechanical properties of cast iron, particularly its plasticity and toughness, resulting in strength even higher than carbon steel. During the casting process, due to the structure and shape of ductile iron castings, not all can be made using a two-box molding method; some products require three or more boxes. When using three or more boxes, manual parting lines are necessary.

[0003] In related technologies, the parting surface is made by hand, resulting in poor flatness, which leads to a high risk of fire during pouring and low production efficiency. Utility Model Content

[0004] The purpose of this application is to provide a tooling for manufacturing fire-proof troughs, which solves the problem that poor flatness of the parting surface during manual casting leads to a high risk of fire during casting and low manufacturing efficiency.

[0005] To achieve the objectives of this application, the following technical solution is provided:

[0006] Firstly, this application provides a tooling for manufacturing a fire-proof channel, comprising:

[0007] A push plate, comprising a first side and a second side disposed opposite to each other in a first direction;

[0008] A handle is provided on the first side;

[0009] A groove-shaped component is disposed on the second side surface. The groove-shaped component extends along a second direction. The groove-shaped component includes a connected forming part and a guiding part, which are arranged sequentially in the second direction.

[0010] The size of the guide portion in the third direction gradually decreases from the end closer to the molding portion to the end farther away from the molding portion, and the first direction, the second direction and the third direction are perpendicular to each other.

[0011] In one embodiment, the guide portion includes a first inclined surface and a second inclined surface connected together, both of which are parallel to the first direction.

[0012] In one embodiment, the angle between the first inclined plane and the second inclined plane is in the range of 50° to 55°.

[0013] In one embodiment, the dimension of the forming part in the third direction is smaller than the dimension of the push plate in the third direction.

[0014] In one embodiment, the cross-section of the molding portion perpendicular to the second direction is trapezoidal.

[0015] In one embodiment, the forming part includes a third inclined surface and a fourth inclined surface disposed opposite to each other in the third direction, the third inclined surface being in contact with the first inclined surface and the fourth inclined surface being in contact with the second inclined surface;

[0016] In the first direction, the distance between the third inclined surface and the fourth inclined surface gradually increases from the end away from the push plate to the end closer to the push plate.

[0017] In one embodiment, the angle between the third inclined plane and the fourth inclined plane is in the range of 85° to 95°.

[0018] In one embodiment, the push plate includes a first plate and a second plate, the first plate extending along the second direction, the second plate extending along the first direction, and the second plate disposed at one end of the first plate near the guide portion in the second direction;

[0019] The first side and the second side are the two opposite sides of the push plate in the first direction.

[0020] In one embodiment, the dimension of the first plate in the third direction gradually decreases from the side closer to the second plate to the side farther away from the second plate.

[0021] In one embodiment, the handle extends along the second direction, and one end of the handle along the second direction is connected to the second plate.

[0022] Compared with the prior art, this application has at least the following beneficial effects:

[0023] 1. In this application, the groove-shaped component includes a forming part and a guiding part. The dimension of the guiding part in the third direction gradually decreases from the end closer to the forming part to the end farther away from the forming part, forming a sloping guiding structure. This facilitates the advancement of the tooling for fabricating the anti-sparking groove and improves the fabrication efficiency of the anti-sparking groove. During the advancement of the groove-shaped component, the forming part can form a regular groove shape, reducing the overall mold closing gap and lowering the risk of sparking in the casting during the ductile iron casting process.

[0024] 2. In this application, the first and second sides of the push plate are arranged opposite each other in a first direction, with the first side facing the operator and the second side facing the parting surface. A handle is provided on the first side of the push plate for easy gripping and control of the tooling by the operator.

[0025] 3. In this application, by setting a push plate between the handle and the groove-shaped part, the push plate can ensure the flatness of the sand mold on both sides during the production of the fire escape groove, thereby improving the forming quality of the fire escape groove.

Detailed Implementation

[0034] The following are specific embodiments of this application, which are described in conjunction with the accompanying drawings to further illustrate the technical solutions of this application. However, this application is not limited to these embodiments.

[0035] In the production of ductile iron castings, some castings with complex structures and shapes, such as intricate internal cavities, large planar structures, or special external contours, require the use of three-box or more molding methods. When using three-box or more molding methods, the joints between different sand boxes need to be manually parted to facilitate mold making and demolding, resulting in a manual parting surface. The formation of this manual parting surface depends entirely on the operator's skill and experience, and its flatness is difficult to control precisely.

[0036] During the casting process, after molten metal is injected into the sand mold cavity, under the influence of high temperature and pressure, the molten metal can leak along the mold closing gap, a phenomenon known as "fire run-out." Fire run-out not only wastes molten metal and increases production costs but also affects the quality of the casting. By setting fire-prevention grooves (also called "fire-blocking grooves" or "overflow grooves") on the parting surface, it is possible to prevent molten metal from overflowing from the parting surface, ensuring the safety of the casting process and the quality of the casting.

[0037] refer to Figure 1 , Figure 2 and Figure 3 This application provides a tooling for manufacturing a fire escape channel, including a push plate 100, a handle 200, and a channel-shaped component 300. The push plate 100 includes a first side 110 and a second side 120 disposed opposite each other in a first direction X. The handle 200 is disposed on the first side 110. The channel-shaped component 300 is disposed on the second side 120 and extends along a second direction Y. The channel-shaped component 300 includes a connected forming portion 310 and a guide portion 320, which are sequentially disposed in the second direction Y. The dimension of the guide portion 320 in the third direction Z gradually decreases from the end closer to the forming portion 310 to the end farther away from the forming portion 310, and the first direction X, the second direction Y, and the third direction Z are all perpendicular to each other.

[0038] The push plate 100 is the main part of the tooling for fabricating the fire escape channel, used to support the channel-shaped part 300 and provide an operating surface. The push plate 100 ensures the flatness of the sand molds on both sides during the fabrication of the fire escape channel, improving the forming quality of the channel. The push plate 100 can be made of metal, possessing sufficient strength and rigidity to withstand the pressure and friction during the fabrication process. The first side 110 and the second side 120 of the push plate 100 are arranged opposite each other in the first direction X, with the first side 110 facing the operator and the second side 120 facing the parting surface.

[0039] A handle 200 is provided on the first side 110 of the push plate 100 to facilitate the operator's grip and control of the tooling. The handle 200 may be made of the same or different material as the push plate 100. A through hole 210 for fingers to pass through is provided on the handle 200. Anti-slip textures may be designed on the surface of the handle 200 to improve grip comfort and stability.

[0040] A groove-shaped component 300 is disposed on the second side 120 of the push plate 100 and is used to form a fire-proof groove on the parting surface. The groove-shaped component 300 extends along a second direction Y, which is perpendicular to the first direction X. The groove-shaped component 300 includes a connected forming part 310 and a guide part 320, which are arranged sequentially in the second direction Y, that is, the forming part 310 is close to the push plate 100, and the guide part 320 is located at the end away from the push plate 100.

[0041] The forming part 310 is the main working part of the groove-forming component 300, used to form the required groove shape on the material. The shape and size of the forming part 310 correspond to the shape and size of the fire-proof groove to be manufactured. The forming part 310 is made of wear-resistant material to ensure stability and accuracy during long-term use.

[0042] The guide section 320 is located at the front end of the forming section 310 and is used to guide the tooling into the sand mold and ensure the accurate formation of the groove. The dimension of the guide section 320 in the third direction Z gradually decreases from the end closer to the forming section 310 to the end farther away from the forming section 310, forming a wedge-shaped structure, which facilitates the advancement of the tooling for making the anti-fire-run groove and improves the efficiency of anti-fire-run groove production. It also makes it easier for the guide section 320 to be inserted into the sand mold, reducing initial resistance and gradually guiding the forming section 310 into the sand mold. During the advancement of the groove-making part 300, the forming section 310 can form a regular groove, reducing the overall mold closing gap and lowering the risk of casting fire during ductile iron casting.

[0043] The first direction X, the second direction Y, and the third direction Z are all perpendicular to each other, forming a three-dimensional coordinate system. In practical applications, the first direction X can be understood as the up-down direction, the second direction Y as the front-back direction, and the third direction Z as the left-right direction.

[0044] refer to Figure 2 , Figure 3 and Figure 4 The guide portion 320 includes a first inclined surface 321 and a second inclined surface 322 connected to each other. Both the first inclined surface 321 and the second inclined surface 322 are parallel to the first direction X. The first inclined surface 321 and the second inclined surface 322 are arranged opposite to each other in the third direction Z, together forming a wedge-shaped structure of the guide portion 320. They intersect or nearly intersect at the end away from the forming portion 310, forming the tip of the guide portion 320.

[0045] In one embodiment, the angle α between the first inclined surface 321 and the second inclined surface 322 is in the range of 50° to 55°. Within this range, the angle α ensures that the guide portion 320 is sufficiently sharp for material insertion while also possessing sufficient strength to withstand stress during operation. When the angle α is less than 50°, the guide portion 320 is too sharp, potentially leading to insufficient strength; when the angle α is greater than 55°, the guide portion 320 is too blunt, potentially increasing resistance to material insertion.

[0046] The dimension of the forming part 310 in the third direction Z is smaller than that of the push plate 100 in the third direction Z, so that the push plate 100 can provide sufficient support and protection for the forming part 310, preventing the forming part 310 from deforming or being damaged during operation. At the same time, the larger size of the push plate 100 also helps to ensure the flatness of the parting surfaces on both sides of the fire escape groove.

[0047] The forming part 310 has a trapezoidal cross-section perpendicular to the second direction Y. The trapezoidal cross-section design corresponds to the shape of the fire escape channel, which can form the required channel shape on the sand mold. The upper and lower bases of the trapezoidal cross-section correspond to the upper opening and bottom of the fire escape channel, respectively, and the two inclined sides of the trapezoid correspond to the side walls of the fire escape channel.

[0048] refer to Figure 3 , Figure 4 and Figure 5 The forming part 310 includes a third inclined surface 311 and a fourth inclined surface 312 disposed opposite to each other in the third direction Z. The third inclined surface 311 is connected to the first inclined surface 321, and the fourth inclined surface 312 is connected to the second inclined surface 322. A smooth transition can be made between the third inclined surface 311 and the first inclined surface 321, and a smooth transition can be made between the fourth inclined surface 312 and the second inclined surface 322, ensuring a smooth transition from the guide part 320 to the forming part 310, and reducing the resistance and wear when the anti-fire groove manufacturing tool moves.

[0049] In the first direction X, the distance between the third inclined surface 311 and the fourth inclined surface 312 gradually increases from the end away from the push plate 100 to the end closer to the push plate 100. This allows the forming part 310 to form a groove with a gradually increasing cross-section on the sand mold. The cross-sectional area of ​​the groove gradually increases from the inlet inward, increasing the parting surface stroke and reducing the fluidity of the molten metal.

[0050] In one embodiment, the included angle β between the third inclined surface 311 and the fourth inclined surface 312 ranges from 85° to 95°. Within this range, the included angle β ensures sufficient volume for the fire-prevention channel without making the channel walls excessively steep. When the included angle β is less than 85°, the channel walls are too steep, resulting in a smaller parting surface travel; when the included angle β is greater than 95°, the channel shape is too flat, affecting the fire-prevention effect.

[0051] The push plate 100 includes a first plate 130 and a second plate 140. The first plate 130 extends along a second direction Y, and the second plate 140 extends along a first direction X. The second plate 140 is disposed at the end of the first plate 130 in the second direction Y, near the guide portion 320. The first plate 130 is the main body of the push plate 100, providing the main support and operating surface; the second plate 140 is the end of the push plate 100, perpendicularly connected to the first plate 130, forming an "L"-shaped structure. This design increases the rigidity and stability of the push plate 100, preventing deformation during use.

[0052] The first side 110 and the second side 120 are two opposing sides of the push plate 100 in the first direction X. The first side 110 is the side of the push plate 100 facing the operator, and the second side 120 is the side of the push plate 100 facing the parting surface. The handle 200 is provided on the first side 110 for easy gripping by the operator; the groove-shaped part 300 is provided on the second side 120 and directly contacts the parting surface.

[0053] Specifically, the dimension of the first plate 130 in the third direction Z gradually decreases from the side closer to the second plate 140 to the side farther away from the second plate 140. This forms a wedge-shaped structure for the first plate 130, reducing the overall weight of the fire escape channel fabrication fixture while maintaining sufficient strength and rigidity. The wedge-shaped structure also helps the operator better control the direction of movement and the applied force of the fire escape channel fabrication fixture.

[0054] The handle 200 extends along the second direction Y, and one end of the handle 200 along the second direction Y is connected to the second plate 140. That is, the handle 200 is connected to both the first plate 130 and the second plate 140, which improves the connection stability between the handle 200 and the push plate 100. The handle 200 extends along the second direction Y and is perpendicular to the second plate 140, allowing the operator to apply uniform force to control the movement of the fireproof groove fabrication fixture along the second direction Y.

[0055] When using the fire escape channel fabrication fixture of this application, the operator holds the handle 200, inserts the guide part 320 into the sand mold, and then pushes the fire escape channel fabrication fixture along the second direction Y, so that the channel forming part 300 forms the fire escape channel on the parting surface. The wedge-shaped design of the guide part 320 makes it easier for the fixture to be inserted into the sand mold, and the cross-sectional design of the forming part 310 ensures that the formed fire escape channel has the required shape and size, improving the fabrication efficiency and quality of the fire escape channel.
