Description

Technical Field

[0001] This utility model relates to the field of casting processing technology, and in particular to a casting mold for the production of metal tees. Background Technology

[0002] Metal tees are pipe fittings used in piping systems to split or merge flows. They typically have three ports (main pipe and two branch pipes) and can change the direction of fluid flow to achieve the function of splitting one flow into two (flow splitting) or merging two flows into one (flow merging). They are mostly made of cast iron, stainless steel, aluminum alloy, etc., and are suitable for transporting media such as water, gas, and oil. They are widely used in industrial pipelines, building water supply and drainage, heating systems and other scenarios.

[0003] A search revealed that the document with publication number "CN216421010U" states that "this utility model relates to the field of mold technology, specifically a casting mold for flywheel production, including an upper mold and a lower mold. The upper and lower molds are of equal size. Four support plates are provided on the upper surface of the upper mold and the lower surface of the lower mold. Each support plate is located at one of the four corners of the upper and lower molds. Connecting holes are provided on the upper and lower molds corresponding to the support plates. Molds are provided at the bottom of the upper mold and the top of the lower mold and cooperate with each other. A through pipe is connected to the lower mold. The through pipe extends into the lower mold and corresponds to a through pipe groove. The through pipe groove is located on the lower mold. A partition is provided on the upper surface of the lower mold, and the partition cooperates with a partition groove provided at the bottom of the upper mold." In use, this utility model isolates the flow of molten iron, preventing burns to workers and avoiding waste of molten iron, saving manpower and resources, and reducing production costs.

[0004] However, during the production of metal tees, because metal tees are tubular and three-way structures, the inner core is difficult to remove after casting. Forcibly removing it can easily damage the tee structure and cause defects. At the same time, due to the tubular structure of the tee, the sealing of the pipe end is particularly important; otherwise, leakage of molten metal may occur, or weak points may appear in the cast tee pipe. In addition, during the casting process, the commonly used serpentine cooling pipes have a large cooling area, but the water volume is small, resulting in poor heat absorption efficiency.

[0005] Therefore, we provide a casting mold for the production of metal tees to solve the above problems. Utility Model Content

[0006] To achieve the above objectives, this utility model provides the following technical solution:

[0007] A casting mold for producing metal tees includes a lower mold support plate. A tee production casting assembly is disposed on the upper side of the lower mold support plate. The tee production casting assembly includes a lower mold casting cavity welded to the upper side of the lower mold support plate. A tee casting inner cavity is disposed inside the lower mold casting cavity. Sealing grooves are provided at the ends of each tee casting inner cavity. A tee horizontal tube inner core is disposed inside each tee casting inner cavity. A tee vertical tube inner core is connected to the right side of each tee horizontal tube inner core. Both the inner ends of the horizontal tube core and the three-way vertical tube core are welded with sealing plates. A cooling water inlet is connected to one side of the lower mold casting cavity, and a cooling water outlet is connected to the other side of the lower mold casting cavity. A limiting groove is formed on the upper inner wall of the lower mold casting cavity. An upper mold casting cavity is installed on the upper side of the lower mold casting cavity. An upper mold support plate is welded to the upper side of the upper mold casting cavity. A casting gate is provided on the upper side of the upper mold support plate. A fixing component is provided on the outer side of the lower mold support plate.

[0008] As a further description of the above technical solution:

[0009] The inner cavity of the three-way casting has the same shape as the inner cavity of the three-way casting inside the upper mold casting cavity, and they fit together. The casting port passes through the upper mold casting cavity and is connected to the inner cavity of the three-way casting.

[0010] As a further description of the above technical solution:

[0011] The inner cores of the tee horizontal tubes are symmetrically arranged on the front and rear sides, and the inner cores of the tee horizontal tubes are interlocked with each other. The inner cores of the tee vertical tubes are connected to the inner cores of the tee horizontal tubes by a slot. The inner cores of the tee vertical tubes and the inner cores of the tee horizontal tubes pass through the middle of the tee casting cavity. There is a casting gap between the inner cores of the tee vertical tubes, the inner cores of the tee horizontal tubes, and the tee casting cavity.

[0012] As a further description of the above technical solution:

[0013] The lower mold casting cavity is connected to the cooling water inlet and cooling water outlet by a pipe, and the cooling water inlet and cooling water outlet are connected to a cooling cavity inside the lower mold casting cavity.

[0014] As a further description of the above technical solution:

[0015] The sealing plates at the ends of the horizontal and vertical tubes of the tee are connected to the sealing groove by a slot, and the casting cavity of the tee and the sealing groove form a sealed structure through the sealing plates.

[0016] As a further description of the above technical solution:

[0017] The upper mold casting cavity and the lower mold casting cavity are fitted together by a limiting groove, and the upper mold casting cavity and the lower mold casting cavity have the same shape.

[0018] As a further description of the above technical solution:

[0019] The fixing assembly includes load-bearing bolts welded to the four corners of the lower mold support plate, and screw holes provided at the four corners of the upper mold support plate. A hand-operated nut is provided on the upper side of the screw hole. The load-bearing bolts pass through the screw holes and are limited by the hand-operated nut. The lower mold support plate and the upper mold support plate are connected by the load-bearing bolts.

[0020] Compared with the prior art, the beneficial effects of this utility model are:

[0021] 1. This utility model produces casting components through a tee. When needed, the upper and lower casting cavities are interlocked to form a tee casting cavity. Molten metal is then injected through the pouring port. The molten metal flows through the gaps between the vertical and horizontal cores of the tee and the casting cavity, gradually filling to form a complete tee structure. Since the metal tee has a complex structure with three channels, after casting, the vertical and horizontal cores can be disassembled separately and removed from the cast tee structure, ensuring that each channel is smooth and defect-free, and facilitating disassembly.

[0022] 2. This utility model uses a T-joint to produce casting components. Before casting, when the lower and upper mold casting cavities are fastened together, the sealing plates at the ends of the horizontal and vertical cores of the T-joint will engage in the sealing groove, thereby sealing the inner cavity of the T-joint casting and preventing molten metal leakage. This ensures stable flow of molten metal during the casting process. During casting, coolant is injected into the cooling chamber, which is connected to the cooling inlet and outlet, through the cooling inlet. The cooling chamber effectively cools the lower mold casting cavity, ensuring rapid solidification of the molten metal, which is then discharged through the cooling outlet, ensuring stable temperature during the casting process. Furthermore, the upper and lower mold casting cavities are fitted together through a limiting groove, which effectively reduces misalignment errors during the fastening process, ensuring casting accuracy and improving product quality.

[0029] 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.

[0030] Please see Figure 1-5 As shown, this utility model provides a technical solution: a casting mold for producing metal tees, including a lower mold support plate 1, a tee production casting assembly 2 disposed on the upper side of the lower mold support plate 1, the tee production casting assembly 2 including a lower mold casting cavity 201 welded to the upper side of the lower mold support plate 1, a tee casting inner cavity 202 disposed on the inner side of the lower mold casting cavity 201, a sealing groove 203 disposed at the end of each tee casting inner cavity 202, a tee horizontal tube inner core 204 disposed on the inner side of each tee casting inner cavity 202, and a tee vertical tube inner core 205 connected to the right side of the tee horizontal tube inner core 204. The ends of the horizontal tube inner core 204 and the three-way vertical tube inner core 205 are both welded with sealing plugs 206. A cooling water inlet 207 is connected to one side of the lower mold casting cavity 201, and a cooling water outlet 208 is connected to the other side of the lower mold casting cavity 201. A limiting groove 209 is opened on the upper inner wall of the lower mold casting cavity 201. An upper mold casting cavity 210 is installed on the upper side of the lower mold casting cavity 201. An upper mold support plate 211 is welded to the upper side of the upper mold casting cavity 210. A casting port 212 is provided on the upper side of the upper mold support plate 211. A fixing component 3 is provided on the outer side of the lower mold support plate 1.

[0031] Furthermore, the three-way casting inner cavity 202 has the same shape as the three-way casting inner cavity 202 inside the upper mold casting cavity 210, and they fit together. The casting port 212 passes through the upper mold casting cavity 210 and connects to the three-way casting inner cavity 202. When needed, the upper mold casting cavity 210 and the lower mold casting cavity 201 are interlocked to form the three-way casting inner cavity 202. At this time, molten metal is injected through the casting port 212. The molten metal flows in the gap between the three-way vertical tube inner core 205, the three-way horizontal tube inner core 204, and the three-way casting inner cavity 202, gradually filling to form a complete three-way structure.

[0032] Furthermore, the tee horizontal tube inner core 204 is symmetrically arranged on both the front and rear sides, and the tee horizontal tube inner cores 204 are interlocked with each other. The tee vertical tube inner core 205 is connected to the tee horizontal tube inner core 204 by a slot. The tee vertical tube inner core 205 and the tee horizontal tube inner core 204 pass through the middle of the tee casting inner cavity 202. There is a casting gap between the tee vertical tube inner core 205, the tee horizontal tube inner core 204 and the tee casting inner cavity 202. When needed, since the metal tee has a complex structure with three channels, after casting, the tee vertical tube inner core 205 and the tee horizontal tube inner core 204 can be disassembled separately and taken out from the cast tee structure, ensuring that the interior of each channel is smooth and defect-free, and facilitating disassembly.

[0033] Furthermore, the lower mold casting cavity 201 is connected to the cooling inlet 207 and the cooling outlet 208 by a pipe. The cooling inlet 207 and the cooling outlet 208 are connected to a cooling chamber inside the lower mold casting cavity 201. When needed, the coolant is injected into the cooling chamber connected to the cooling inlet 207 and the cooling outlet 208 through the cooling inlet 207. The cooling chamber effectively cools the lower mold casting cavity 201 to ensure that the molten metal solidifies quickly and is then discharged through the cooling outlet 208 to ensure stable temperature during the casting process.

[0034] Furthermore, the sealing plates 206 at the ends of the tee horizontal tube inner core 204 and the tee vertical tube inner core 205 are connected to the sealing groove 203 by a slot. The tee casting inner cavity 202 and the sealing groove 203 form a sealed structure through the sealing plates 206. When needed, when the lower mold casting cavity 201 and the upper mold casting cavity 210 are fastened together, the sealing plates 206 at the ends of the tee horizontal tube inner core 204 and the tee vertical tube inner core 205 will be inserted into the sealing groove 203, thereby sealing the tee casting inner cavity 202, preventing molten metal leakage, and ensuring the stable flow of molten metal during the casting process.

[0035] Furthermore, the upper mold casting cavity 210 and the lower mold casting cavity 201 are fitted together by a limiting groove 209. The upper mold casting cavity 210 and the lower mold casting cavity 201 have the same shape. When needed, the upper mold casting cavity 210 and the lower mold casting cavity 201 are fitted together by the limiting groove 209, which can effectively reduce the misalignment error that occurs during the fitting process, ensure casting accuracy, and improve product quality.

[0036] Furthermore, the fixing component 3 includes load-bearing bolts 301 welded to the four corners of the lower mold support plate 1, and screw holes 302 provided at the four corners of the upper mold support plate 211. A hand-operated nut 303 is provided on the upper side of the screw hole 302. The load-bearing bolts 301 pass through the screw holes 302 and are limited by the hand-operated nut 303. The lower mold support plate 1 and the upper mold support plate 211 are connected by the load-bearing bolts 301. When needed, the load-bearing bolts 301 are passed through the screw holes 302 outside the upper mold support plate 211, and then the hand-operated nut 303 is tightened, thereby achieving the effect of clamping the upper mold casting cavity 210 and the lower mold casting cavity 201 through the lower mold support plate 1 and the upper mold support plate 211, ensuring the sealing effect.

[0037] Working principle: When needed, first place the lower mold support plate 1 in the desired position, then assemble the tee horizontal pipe inner core 204 and the tee vertical pipe inner core 205, inserting them into the tee casting inner cavity 202 within the lower mold casting cavity 201. Also, insert the sealing plates 206 at the ends of the tee horizontal pipe inner core 204 and the tee vertical pipe inner core 205 into the sealing grooves 203. After preparation, tightly fit the upper mold casting cavity 210 under the upper mold support plate 211 with the lower mold casting cavity 201 through the limiting groove 209. Simultaneously, the load-bearing bolts 301 will penetrate the screw holes 302 at the four corners of the upper mold support plate 211. Finally, use the hand-operated nuts 303 to tighten the upper mold support plate 211. The 11 and the lower mold support plate 1 are squeezed together to enhance the sealing effect. Finally, the molten metal is injected through the casting port 212. As the metal tee is formed, the cooling water inlet 207 is injected into the cooling chambers in the lower mold casting cavity 201 and the upper mold casting cavity 210. After heat absorption, the coolant is discharged from the cooling water outlet 208. After solidification, the inner core 205 of the tee vertical pipe is first pulled out from the tee casting inner cavity 202, and then the inner cores 204 of the two tee horizontal pipes are pulled out to form the inner cavity of the metal tee. Then the upper mold casting cavity 210 and the lower mold casting cavity 201 are opened to remove the formed metal tee. This completes the process of using a casting mold for the production of a metal tee.
