[0024] To make the objectives, technical solutions, and advantages of this utility model clearer, the embodiments of this utility model will be described in further detail below with reference to the accompanying drawings.

[0025] Example 1: Reference Figures 1 to 3 This application provides a mold for a pouring basin, including a base plate 1 with a through hole 12, a support member 11 at the bottom of the base plate 1, the support member 11 creating a gap between the base plate 1 and the ground, and also including a pouring frame 2, a jig 3, and a pouring block 4. The pouring frame 2 includes multiple side plates that form a cavity structure with open ends. The pouring frame 2 is disposed on the base plate 1, and the jig 3 is disposed inside the pouring frame 2. The bottom of the fixture 3 is provided with a threaded hole 31. The mold of the sprue basin also includes bolts 5. The bolts 5 pass through the through hole 12 and the threaded hole 31 in sequence to fix the fixture 3 to the base plate 1. The top of the fixture 3 is provided with an opening 32. The bottom of the gate block 4 has an opening. The gate block 4 is set on the fixture 3, and the opening corresponds to the opening 32. The gate block 4 is provided with a positioning pin 41. The positioning pin 41 passes through the opening and is fixed in the opening 32 to fix the gate block 4 on the fixture 3.

[0026] In this embodiment, the support member 11 is made of high-strength cast iron, possessing excellent compressive strength and stability, capable of bearing the weight of the base plate 1 and the entire mold during long-term use. The bottom shape of the support member 11 is designed as a slightly outward-expanding trapezoid, increasing the contact area with the ground when placed on it, further enhancing overall stability and preventing the mold from shaking or tipping over. Simultaneously, at the welding points between the support member 11 and the base plate 1, the welding surfaces are ground to remove rust, oil, and other impurities, ensuring welding quality and forming a robust, integrated structure between the support member 11 and the base plate 1.

[0027] The edges of the through hole 12 are chamfered, and a wear-resistant metal bushing is inlaid on the inner wall of the through hole 12. A high-hardness brass bushing is selected, which is not only wear-resistant but also reduces the coefficient of friction between the bolt 5 and the wall of the through hole 12, making the insertion and removal of the bolt 5 smoother and extending the service life of the through hole 12. Regarding the diameter tolerance of the through hole 12, a suitable clearance fit is ensured between the bolt 5 and the through hole 12, guaranteeing smooth installation without affecting the positional accuracy of the fixture 3 due to excessive clearance.

[0028] The threaded hole 31 of the fixture 3 is drilled first and then tapped. During drilling, the perpendicularity of the hole is ensured using a high-precision drilling machine with a suitable drill bit. After drilling, a tap is used for tapping. Appropriate cutting fluid is used during tapping to ensure the surface quality and accuracy of the thread. Thread-locking agent is applied inside the threaded hole 31 to fill the tiny gaps between the threads, enhancing the friction of the threaded connection and effectively preventing the bolt 5 from loosening due to mold vibration, ensuring that the fixture 3 is always firmly fixed to the base plate 1.

[0029] A ring-shaped groove is provided around the opening 32 at the top of the jig 3. During casting, the casting sand can partially fill the groove, increasing the tightness of the connection between the gate block 4 and the jig 3 at this part, making the structure of the caster basin 7 more robust after molding. Regarding the dimensional accuracy of the opening 32, the shape of the opening 32 is subject to form and position tolerance control to ensure that its roundness or squareness meets the requirements and can cooperate with the positioning pin 41, ensuring the accuracy of the installation position of the gate block 4, thereby ensuring the molding quality of the caster basin 7.

[0030] The side plates are made of steel plates of moderate thickness, whose strength is sufficient to withstand the weight and pressure of the cast sand. After selecting the steel plates, their surfaces must be treated for rust removal and prevention. First, the rust and oxide scale on the surface are removed by sandblasting, and then a layer of anti-rust paint is sprayed on to prevent the side plates from rusting during use, which would affect their performance and service life. It also prevents rust from mixing into the cast sand and affecting the quality of the pouring basin 7.

[0031] The surfaces of the opening and the locating pin 41 undergo fine machining to achieve a high level of surface finish. For example, grinding is used to control the surface roughness to below Ra0.8, which greatly reduces the friction during the fit, making the insertion and removal of the locating pin 41 smoother, and also improving the tightness of the fit and the accuracy of the positioning. Regarding the fit precision, the cylindricity of the locating pin 41 and the opening are controlled within the allowable range, ensuring that the fit achieves the positioning function without affecting the installation and fixation of the gate live block 4 due to excessive tightness or looseness.

[0032] A layer of high-temperature resistant sealant is applied to the mating surfaces of the gate block 4 and the fixture 3. The sealant cures at high temperatures during casting, further enhancing the seal between the two and preventing casting sand from seeping into unwanted areas, thus ensuring the molding quality of the gating basin 7. Multiple corresponding positioning pin holes are provided on the sides of the gate block 4 and the fixture 3. Positioning pins are inserted for lateral positioning assistance. This, combined with the positioning methods using openings, holes 32, and positioning pin blocks 41, ensures the accuracy and stability of the gate block 4's placement on the fixture 3 from multiple angles, ensuring that the dimensions and shape of each part of the gating basin 7 meet design requirements during casting.

[0033] By adopting the above technical solution and using a non-integrated frame, the mold production cost is reduced, the weight is light, and it can be quickly disassembled, making the entire manufacturing process of the sprue basin 7 simple and convenient.

[0034] Example 2: In one feasible embodiment, the casting frame 2 includes two first side plates 21, which are fixedly installed on the base plate 1 and are disposed opposite to each other on both sides of the base plate 1; and two second side plates 22, which are disposed opposite to each other on the base plate 1, with the two ends of one second side plate 22 connected to the first ends of the two first side plates 21 and the two ends of the other second side plate 22 connected to the second ends of the two first side plates 21.

[0035] In this embodiment, mounting holes are precisely drilled on the base plate 1 corresponding to the mounting positions of the first side plate 21. The number of mounting holes can be reasonably determined based on factors such as the length and weight of the first side plate 21, with one mounting hole set every 30-50 cm to ensure the firmness of the first side plate 21 when it is fixedly installed on the base plate 1. Matching holes are also machined at corresponding positions on the bottom of the first side plate 21, and then high-strength fastening bolts are used to fix the first side plate 21 to the base plate 1 through these holes. Before installing the fastening bolts, an appropriate amount of anti-loosening grease is applied to the threaded portion of the fastening bolts to prevent the fastening bolts from loosening due to vibration or other reasons during mold use. A right-angle ruler can be used for calibration during installation to ensure the verticality of the first side plate 21 after installation, so that the first side plate 21 and the edge of the base plate 1 are strictly perpendicular, with the error controlled within a very small range, ensuring the accuracy of subsequent connection with the second side plate 22 and the regularity of the entire casting frame 2 structure.

[0036] A reinforcing rib is welded longitudinally on the inner side of the first side plate 21. The reinforcing ribs can be evenly distributed with a spacing of 20-30 cm. The shape of the reinforcing ribs can be triangular or rectangular. The thickness and height of the reinforcing ribs are determined according to the thickness of the first side plate 21 and the overall mold usage requirements. This is to increase the first side plate 21's ability to withstand the weight of the poured sand and the lateral pressure during pouring, prevent deformation, effectively improve the bending strength of the first side plate 21, ensure that it is not easily deformed during use, and maintain the stable structure of the pouring frame 2.

[0037] In one feasible embodiment, the two ends of the second side plate 22 are connected to the two first side plates 21 by a combination of riveting and welding. Riveting holes are drilled at corresponding positions, and rivets of appropriate specifications are used for initial fixation. Then, based on the rivet fixation, intermittent welding is performed along the edge of the connection. The interval between welding can be controlled at 5-10 cm, which can ensure the firmness of the connection and, to a certain extent, avoid the deformation of the side plates caused by large thermal stress generated by continuous welding.

[0038] Example 3: Reference Figure 2 In one feasible embodiment, a groove 211 is provided at both the first and second ends of the first side plate 21, and both ends of the second side plate 22 are fitted into the groove 211 so that the first side plate 21 and the second side plate 22 form a casting frame 2. A slot is also provided on the base plate 1, and a protrusion 221 is provided on the second side plate 22 corresponding to the slot. When the second side plate 22 is fitted into the groove 211, the protrusion 221 is inserted into the slot.

[0039] In this embodiment, the width of the groove 211 is determined based on the thickness of the second side plate 22. The width of the groove 211 is slightly larger than the actual thickness of the second side plate 22 by 0.5-1 mm, ensuring that the second side plate 22 can be smoothly inserted without causing instability due to excessive gaps. The depth of the groove 211 is designed based on the height of the second side plate 22 and the structural stability requirements of the entire casting frame 2, typically one-third to one-half of the height of the second side plate 22. The corners of the groove 211 are rounded, with a radius of 2-5 mm. This prevents scratches on the side plate surface due to sharp corners during the insertion of the second side plate 22, reduces stress concentration, and improves the durability of the groove 211. After the surface of the groove 211 is processed, it is polished to control the surface roughness to below Ra1.6, making the fit between the second side plate 22 and the groove 211 tighter, reducing gaps, and thus enhancing the sealing after connection, preventing casting sand from seeping out from the groove 211.

[0040] The protrusion 221 is designed in a regular shape, such as a rectangle or trapezoid, and its dimensions are strictly matched to the slot on the base plate 1. The width of the protrusion 221 is slightly smaller than the width of the slot by 0.2-0.5 mm to ensure smooth insertion into the slot. The length of the protrusion 221 is determined based on the width of the second side plate 22 and the stability requirements of the connection; generally, the length is not less than one-third of the width of the second side plate 22. The height of the protrusion 221 matches the depth of the slot, and the height difference is usually controlled within ±0.5 mm to ensure that the second side plate 22 is stably positioned vertically after the protrusion 221 is fully inserted into the slot, preventing vertical wobbling.

[0041] Regarding the fit between the slot and the protrusion 221, a small amount of grease is applied to the inner wall of the slot to make the protrusion 221 insert into the slot more smoothly and securely. A small elastic washer can be placed at the bottom of the slot. When the protrusion 221 is inserted into the slot, the elastic washer will be compressed and deformed, generating an upward elastic force, further enhancing the tightness of the connection between the protrusion 221 and the slot, ensuring that the second side plate 22 can be accurately fixed in both horizontal and vertical directions, and together with the first side plate 21, forming a stable casting frame 2.

[0042] Example 4: Continue to refer to Figure 2 In one feasible embodiment, a through groove is provided on the second side plate 22. The mold of the sprue basin of this application also includes a handle 6, which passes through the side of the second side plate 22 away from the jig 3 and partially extends out of the through groove so that the handle 6 is fixed on the second side plate 22.

[0043] In this embodiment, the position of the through groove is determined based on the ideal position of the handle after the final molding of the gating bowl 7 and the ease of operation. It is opened at a relatively central and appropriately high position on the second side plate 22. For example, if the height of the gating bowl 7 is about 50 cm, the through groove can be opened at a height of 20-30 cm from the bottom of the second side plate 22 to ensure that the handle can be positioned in a convenient gripping position when it is poured laterally. The size of the through groove should be adapted to the outer dimensions of the handle 6. Its length is usually 2-5 mm larger than the lateral dimension of the handle 6 so that the handle 6 can pass through smoothly; the width of the through groove should be 1-3 mm larger than the thickness of the handle 6 to ensure that the handle 6 has enough room to move within the through groove for easy installation and operation, and will not wobble or become unstable due to excessive gaps.

[0044] The through groove can be machined using wire cutting technology. This process can precisely control the shape and size of the through groove, ensuring that the straightness and perpendicularity of the through groove meet the required geometric tolerances, thus maintaining good directionality when the handle 6 passes through it. After the through groove is machined, its edges must be deburred. Sandpaper or small grinding tools can be used to smooth the edges to prevent scratching the operator's hands when the handle 6 passes through or during subsequent use. It also avoids the presence of burrs affecting the tightness of the fit between the handle 6 and the through groove, thereby ensuring the stability of the entire structure.

[0045] The handle 6 can be made of high-temperature resistant and high-strength stainless steel, which can withstand the high-temperature environment during pouring and has good corrosion resistance, ensuring good performance even after multiple uses. The handle 6 can be designed with a cylindrical grip at one end for easy handling; the diameter of the grip can be ergonomically designed to be approximately 2-3 cm for comfortable hand grip. The other end is a flat connecting part that passes through a groove to connect with the second side plate 22. The flat design increases the contact area with the second side plate 22, making the connection more secure. Small holes can also be made in the connecting part for subsequent fixing or auxiliary positioning operations, such as inserting small pins to further secure the handle 6 to the second side plate 22.

[0046] After the handle 6 passes through the through groove, to ensure it is firmly fixed to the second side plate 22, a high-temperature resistant sealant can be applied to the contact area between the connecting part and the through groove. The sealant fills the tiny gaps between them and acts as an adhesive, preventing the handle 6 from loosening or shifting during use. Additionally, a small metal pressure plate can be installed on each side of the flat connecting part of the handle 6. The pressure plates are fixed to the second side plate 22 with screws, clamping the connecting part of the handle 6 in the middle to further enhance the fixing effect. This ensures that the handle 6 can be stably held in the set position during handle casting, so that the shape and position of the cast handle meet the design requirements, ensuring the overall quality of the pouring basin 7.

[0047] Example 5: Continue to refer to Figure 2 In one feasible embodiment, a first pin hole 13 is provided on the base plate 1, and a second pin hole is provided on the bottom of the first side plate 21 corresponding to the first pin hole 13. The first side plate 21 is fixedly installed to the base plate 1 by a positioning pin that passes through the first pin hole 13 and the second pin hole in sequence.

[0048] In this embodiment, the position of the first pin hole 13 on the base plate 1 is determined based on the size of the first side plate 21 and the overall stress distribution. Typically, they are positioned at equal intervals along the two edges of the base plate 1, corresponding to the bottom of the first side plate 21. For example, for a first side plate 21 approximately 1 meter long, a first pin hole 13 can be placed every 20-30 centimeters along its length to ensure even stress distribution when fixing the first side plate 21, making the connection between the first side plate 21 and the base plate 1 more stable and preventing the side plate from shaking or deforming due to uneven local stress. The position of the first pin hole 13 must precisely correspond to the position of the second pin hole at the bottom of the first side plate 21. This can be ensured by pre-marking the base plate 1 and the first side plate 21 or by using a mold for positioning.

[0049] The size of the first pin hole 13 should be determined according to the specifications of the selected locating pin. Its diameter is generally 0.1-0.3 mm larger than the outer diameter of the locating pin to ensure that the locating pin can be inserted smoothly. The machining of the second pin hole at the bottom of the first side plate 21 should correspond to the first pin hole 13 on the base plate 1. The size of the second pin hole is designed according to the specifications of the locating pin, and its diameter tolerance is consistent with that of the first pin hole 13 to ensure the fitting accuracy between the locating pin and the second pin hole.

[0050] A wear-resistant bushing is inlaid in the second pin hole. A copper alloy bushing with high hardness is selected. The inner diameter of the bushing is adapted to the outer diameter of the positioning pin. Its outer diameter is installed in the second pin hole by interference fit. This protects the inner wall of the second pin hole and ensures good fit accuracy between the positioning pin and the bushing. This makes the positioning pin smoother when inserted and pulled out. At the same time, it can also enhance the positioning effect of the positioning pin on the first side plate 21 and ensure the positional stability of the first side plate 21 after it is fixed on the base plate 1.

[0051] Example 6: In one feasible embodiment, the cross-sectional shape of the gate block 4 is a square block or a circular block.

[0052] In this embodiment, when the cross-sectional shape of the gate block 4 is a square block, the side lengths are processed according to design requirements, and the dimensional tolerance can be set within ±0.1 mm to ensure accuracy when mating with the fixture 3 and other related components. The four corners of the square block should be rounded, with a radius of 2-5 mm. During installation and use, this avoids scratching operators due to sharp corners and reduces stress concentration, thereby improving the structural strength and durability of the gate block 4.

[0053] When the cross-sectional shape of the gate block 4 is circular, the diameter tolerance range can be set to approximately ±0.05 mm. High-precision turning processes ensure the accuracy of the diameter, allowing for a tight and precise fit with the corresponding openings 32 and other structures on the fixture 3. The circumferential surface of the circular block undergoes fine grinding to control the surface roughness below Ra0.4. This reduces friction when in contact with the fixture 3, making installation smoother and improving the seal between them. This prevents leakage of casting sand at the joint, ensuring the molding quality of the gate basin 7.

[0054] When machining the circular gating block 4, the deviation of its center position must be controlled within 0.03 mm to ensure that the entire circular block has good rotational symmetry. This plays a crucial role in maintaining a stable position and shape during subsequent installation on the jig 3 and during the casting process. At the same time, for any openings, holes, or other structures on the circular block that may mate with the positioning pin block 41, it must be ensured that they are evenly distributed around the center and machined strictly according to the designed angles and positions to meet the functional requirements of the gating basin 7.

[0055] Example 7: In one feasible embodiment, the jig 3, the casting frame 2, and the gate block 4 are all made of fiberglass.

[0056] In this embodiment, the mold for the sprue basin 7 is made of fiberglass, which reduces the production cost of the mold, makes it lightweight and quick to disassemble, and makes the entire manufacturing process of the sprue basin 7 simple and convenient.

[0057] Fiberglass has a certain degree of elasticity and machinability, making it easy to design easily disassembled structures on various parts of the mold. Taking the casting frame 2 as an example, its side plates are connected by slots and blocks. When using fiberglass, its plasticity allows for more precise dimensional control when manufacturing the blocks and slots, ensuring a tight connection while allowing for easy separation by applying appropriate external force when disassembly is needed. In the case where the fixture 3 is fixed to the base plate 1 with bolts 5, the threaded holes 31 on the fiberglass fixture 3 are less prone to thread damage or stripping compared to metal fixtures when the bolts 5 are repeatedly tightened. This is because fiberglass itself has a certain degree of toughness and can withstand a certain degree of stress variation, thus ensuring the reliability of the connection structure during repeated disassembly and installation. The gate block 4 and the fixture 3 are fixed together by the positioning pin 41. The fiberglass gate block 4 can better cooperate with the positioning pin 41 at the opening. Moreover, due to its light weight, it is easier to operate during disassembly and will not cause damage to related parts during disassembly due to excessive weight. Overall, it enables the quick and convenient disassembly of all parts of the gate basin 7 mold.

[0058] Example 8: Reference Figure 3 This utility model also discloses a pouring basin 7, which is manufactured using the mold described above. A slag-blocking plate is provided at the pouring port of the pouring basin 7. The material of the pouring basin 7 is resin sand or water glass sand.

[0059] In this embodiment, the slag-blocking plate is made of ceramic material or high-chromium alloy material that is resistant to high temperature, wear, and has good chemical stability. Ceramic materials, such as alumina ceramics, have advantages such as high hardness, high temperature resistance, and strong chemical inertness, which can effectively prevent impurities such as molten slag that may be generated during the pouring process of the pouring bowl 7 from entering the pouring channel. Moreover, its surface is relatively smooth and does not easily accumulate slag, which helps to keep the pouring opening of the pouring bowl 7 clean. High-chromium alloy material has excellent high temperature resistance and high strength and toughness. When subjected to the scouring of high-temperature molten metal and the impact of slag, it is not easy to break or deform, and can stably play the role of slag blocking for a long time.

[0060] The slag-retaining plate can be installed at the pouring gate of the pouring basin 7 by either embedding or fixing it with connectors. For embedded installation, a groove adapted to the shape of the slag-retaining plate is pre-machined at the corresponding position at the pouring gate of the pouring basin 7. The size of the groove should ensure that the slag-retaining plate can be tightly embedded in it, with a depth of two-thirds of the thickness of the slag-retaining plate and a width slightly wider than the slag-retaining plate by 0.5-1 mm, to facilitate installation. During installation, a high-temperature resistant adhesive is applied to the groove. After the slag-retaining plate is embedded, the adhesive further enhances the connection between the slag-retaining plate and the pouring basin 7, preventing it from falling off during use. If a connector is used for fixing, mounting holes are set on the edge of the slag-blocking plate, and matching holes are drilled at the corresponding positions of the pouring opening of the pouring basin 7. High-temperature resistant rivets are used to fix the slag-blocking plate to the pouring basin 7 through these holes. The specifications of the rivets should be reasonably selected according to the size and weight of the slag-blocking plate and the operating conditions of the pouring basin 7 to ensure reliable fixing. After installation, the connectors should be treated to prevent loosening, such as by adding anti-loosening washers, to prevent the slag-blocking plate from loosening or shifting due to vibration or other reasons.

[0061] The shape of the slag-blocking plate is usually determined based on the shape of the pouring opening of the pouring basin 7 and the specific slag-blocking requirements. If the pouring opening is circular, the slag-blocking plate can be designed as circular or fan-shaped. The diameter of the circular slag-blocking plate should generally be slightly larger than the inner diameter of the pouring opening, with the excess portion being about 5-10 mm. This ensures complete coverage of the pouring opening and achieves a good slag-blocking effect. For fan-shaped slag-blocking plates, the appropriate central angle and radius can be set as needed, and multiple fan-shaped slag-blocking plates can be combined to completely cover the pouring opening. If the pouring opening is square, the slag-blocking plate can be designed as square or rectangular, with its side length being 5-10 mm larger than the side length of the pouring opening to ensure the integrity of the slag-blocking area. At the same time, the thickness of the slag-blocking plate should also be determined based on the actual usage environment. For pouring basin 7 that withstands large flow rates and impact forces, the thickness of the slag-blocking plate can be set at about 5-10 mm to have sufficient strength to block slag. For situations with smaller flow rates and weaker impact forces, a thickness of 3-5 mm is sufficient.

[0062] Resin sand is a molding material made by mixing synthetic resin as a binder with raw sand such as quartz sand. Its advantages include good plasticity; when using the aforementioned gating basin 7 mold for molding, it can effectively fill all parts of the mold, especially complex areas such as the gap between the jig 3 and the gating block 4, accurately replicating the shape of the gating basin 7. After curing, resin sand has high strength and can withstand certain external forces, making it less prone to damage during demolding, subsequent handling, and use. Furthermore, resin sand has good collapsibility, facilitating the recycling of used sand after the gating basin 7 is used. Through specific recycling processes, impurities such as the resin film on the surface of the sand particles can be removed, allowing the raw sand to be recycled, reducing production costs, and meeting environmental protection requirements. During the preparation of resin sand, the ratio of resin to raw sand must be strictly controlled. Generally, the amount of resin added is about 1%-3% of the weight of the raw sand, which can be adjusted appropriately according to specific process requirements and the performance needs of the gating basin 7. Thorough and uniform mixing is essential to ensure that each sand particle is evenly coated with resin, achieving good bonding and molding quality.
