Description

TECHNICAL FIELD

[0001] The present application relates to the field of lost foam casting pouring technology, and more particularly, relates to an integrated lost foam casting pouring device and a working method thereof. BACKGROUND

[0002] Lost foam casting pouring is an advanced casting process, and its core step is to bond and combine paraffin or foam models similar in size and shape to the final casting, form a complete model cluster, and then carefully brush the model cluster with refractory coating and dry it thoroughly to ensure that the coating layer is firm and uniform. Then, the processed model cluster is buried in dry quartz sand and tightly fixed by vibration molding. In the pouring process, the molten metal liquid is injected into the negative pressure environment, at which time the model rapidly gasifies at high temperature, and the liquid metal accurately occupies the original model position. With the solidification and cooling of the metal, a casting with the same shape as the model is finally formed. This casting method is widely used in the manufacture of various complex and high-precision castings due to its high casting precision, excellent surface quality, and relatively simple process flow, greatly improving the production efficiency and product quality of the casting industry.

[0003] According to the patent document CN103008542B, a lost foam casting weight pressurizing pouring device is disclosed, which has a sand box sealing cover and a pouring cup, wherein: the sand box sealing cover is composed of two half structures, the combination part of the two half structures is provided with a sealing structure, the middle part of the sand box sealing cover is provided with a circular hole through which the pouring cup passes, the pouring cup passes through the circular hole, the upper end of the pouring cup is connected with a cylindrical base, the cylindrical base is composed of two half structures, the lower part of the cylindrical base is provided with a support which can be supported on the sand box sealing cover, the upper part of the cylindrical base is provided with a cylindrical pressurizing cylinder, the cylindrical pressurizing cylinder is provided with a funnel-shaped piston, the upper surface of the funnel-shaped piston is concave and tapered, the lower surface is provided with a circular opening, a reverse door is installed at the opening position, and a weight is placed on the funnel-shaped piston. Compared with the prior art, the structure is compact, and the defects of casting shrinkage, shrinkage, insufficient pouring, and insufficient pouring are solved.

[0004] During casting operations, workers typically need to manually and accurately place the prepared casting molds into the designated casting positions. However, in practice, due to human factors, it is often difficult to ensure that the mold placement is completely precise. Such minute deviations can significantly affect the final casting quality, leading to defects or non-compliance with design requirements. Furthermore, the molten metal used in the casting process is usually at extremely high temperatures and is considered liquid metal. Workers not only face the serious safety hazard of being burned by the high-temperature molten metal during handling and casting operations, but also risk accidental spillage of molten metal due to the instability of human operation. This not only directly threatens worker safety but may also cause accidents on the production site, resulting in equipment damage, production interruptions, and a series of other serious consequences, ultimately affecting the smooth progress of the entire production process and the stability of product quality. Summary of the Invention

When workers are handling and pouring, they not only face the serious safety hazard of being burned by the high-temperature molten metal, but also, due to the instability of human operation, there is a high possibility that the molten metal may be accidentally splashed out. This will not only directly threaten the safety of workers, but may also cause accidents on the production site, resulting in a series of serious consequences such as equipment damage and production interruption, thereby affecting the smooth progress of the entire production process and the stability of product quality.

The bottom of the bottom pull block 1211 extends to the bottom of the support plate 115 through the support plate groove 116.

A push-pull horizontal plate 1214 is fixedly connected to the rear side of the 18. U-shaped pull frames 1215 are fixedly connected to the left and right sides of the front side of the push-pull horizontal plate 1214. The outer walls of the two U-shaped pull frames 1215 are slidably connected to the inner walls of the two U-shaped side guide plates 113. The mold mechanism 2 includes two mold side pull plates 21. The outer walls of the two mold side pull plates 21 are slidably connected to the inner walls of the two U-shaped side guide plates 113. The top and bottom of the two mold side pull plates 21 are fixedly connected to the front side of the inner side of the two U-shaped pull frames 1215. A mold connecting sleeve 22 is fixedly connected to the front side of the inner side of the two mold side pull plates 21. A mold body 23 is fixedly connected to the inner wall of the mold connecting sleeve 22. The bottom of the mold body 23 is fixedly connected to the top of the sliding plate 1111. When casting is required, the heated molten metal is first injected into the inner wall of the casting tank 1115. Then, the electric push rod 1112 is activated. After the electric push rod 1112 is activated, its push rod extends backward, pushing the bottom pull block 1211 to move backward along the tray slide groove 116. When the bottom pull block 1211 moves backward, it drives the horizontal pull rod 1210 to move backward in sync. During the backward movement of the horizontal pull rod 1210, on the one hand, through the rotational connection between the rotating rod 1212 and the baffle hinge block 1119, the baffle 1118 is pulled downward around the rotation point of its connection with the U-shaped side guide plate 113, so that the baffle 1118 gradually opens, and the nozzle of the casting nozzle 1117, which was originally covered by the baffle 1118, is exposed. On the other hand, the horizontal pull rod 121... 0 drives the columnar push-pull rod 1213 to slide backward on the inner wall of the guide block 118. The push-pull horizontal plate 1214 at the rear end of the columnar push-pull rod 1213 moves backward accordingly. The push-pull horizontal plate 1214 drives the two mold side pull plates 21 to slide backward on the inner wall of the U-shaped side guide plate 113 through the two U-shaped pull frames 1215. Since the mold connecting sleeve 22 is fixedly connected to the front side of the inner side of the mold side pull plate 21, the mold body 23 is fixedly connected to the inner wall of the mold connecting sleeve 22, and the bottom of the mold body 23 is fixedly connected to the top of the sliding plate 1111, and the sliding plate 1111 is slidably connected to the front side of the bottom of the inner side of the pouring area positioning plate 1110, the mold body 23 will move backward precisely to the pouring area as the mold side pull plate 21 moves backward. Meanwhile, the backward movement of the horizontal tie rod 1210 also drives the two short columnar rods 125 to move backward via the two pull blocks 126. The short columnar rods 125 drive the U-shaped pull block 123 to slide on the outer wall of the concave block 122. The columnar horizontal abutment rod 127 fixed inside the U-shaped pull block 123 moves accordingly. The elliptical sliding block 128 fitted on the outer wall of the columnar horizontal abutment rod 127 rotates under the action of the columnar horizontal abutment rod 127. The rotating side plate fixed at the top of the elliptical sliding block 128... 129 slides and rotates on the top of the inner wall of the concave block 122. Since the top of the inner side of the two rotating side plates 129 are rotatably connected to the left and right sides of the outer wall of the pouring nozzle 1117, the rotation of the rotating side plates 129 will drive the pouring nozzle 1117 to rotate around the movable connection point at the top of the pouring nozzle connection plate 1114, adjusting the spray angle of the pouring nozzle 1117 so that the nozzle is pulled downwards to the top of the mold body 23 in the pouring area. When the electric push rod 1112 is pushed to the appropriate position, the mold body 23 accurately reaches the pouring area. After the pouring nozzle 1117 is also adjusted to the appropriate spray angle, the heated molten metal in the pouring tank 1115 is transported to the pouring nozzle 1117 through the heat insulation pipe 1116 under pressure, and is accurately sprayed into the mold body 23 from the pouring nozzle 1117 to complete the casting pouring process. After casting and pouring are completed, simply reverse the electric push rod 1112. After the electric push rod 1112 is reversed, its push rod retracts forward. On the one hand, through the rotational connection between the rotating rod 1212 and the baffle hinge block 1119, the baffle 1118 is pushed to rotate upward around the rotation point of its connection with the U-shaped side guide plate 113, so that the baffle 1118 gradually closes and covers the nozzle of the pouring nozzle 1117 again. On the other hand, the horizontal tie rod 1210 drives the columnar push-pull rod 1213 to slide forward on the inner wall of the guide block 118. The mold body 23 will move forward precisely out of the pouring area as the mold side pull plate 21 moves forward.

[0022] In addition, the present invention also relates to a method for operating an integrated lost foam casting pouring device, comprising the following steps: Step 1: Conduct a comprehensive inspection of the integrated lost foam casting pouring device to ensure that all components are securely connected and undamaged, that the moving parts of the electric push rod 1112, rotating rod 1212, and columnar push-pull rod 1213 move smoothly, and that the pouring liquid tank 1115, heat insulation pipe 1116, and pouring nozzle 1117 are free from blockages and leaks. Step 2: The metal raw materials for casting are placed in a heating device and heated to reach a suitable pouring temperature; Step 3: After the molten metal is heated, according to the casting and pouring operation process described above, the heated molten metal is injected into the inner wall of the pouring tank 1115. The electric push rod 1112 is started to make the mold body 23 accurately reach the pouring area. The pouring nozzle 1117 is adjusted to a suitable spraying angle. Then, the heated molten metal in the pouring tank 1115 is transported to the pouring nozzle 1117 through the heat insulation pipe 1116 under pressure, and accurately sprayed into the mold body 23 from the pouring nozzle 1117. Step 4: After the molten metal is sprayed into the mold body 23, wait for a period of time to allow the molten metal to cool and solidify inside the mold; Step 5: After the molten metal has completely cooled and solidified, start the electric push rod 1112 in reverse again, so that the mold body 23 moves forward precisely out of the pouring area as the mold side pull plate 21 moves forward, and then the formed casting is taken out from the mold body 23.

[0023] The working principle of this invention is as follows: First, the heated molten metal is injected into the inner wall of the casting tank 1115. Then, the electric push rod 1112 is activated. After the electric push rod 1112 is activated, its push rod extends backward, pushing the bottom pull block 1211 to move backward along the slide groove 116 of the support plate. When the bottom pull block 1211 moves backward, it drives the horizontal pull rod 1210 to move backward synchronously. During the backward movement of the horizontal pull rod 1210, it pulls the baffle 1118 to rotate downward around the rotation point of its interaction with the U-shaped side guide plate 113, so that the baffle 1118 gradually opens, revealing the nozzle of the casting nozzle 1117 that was originally covered by the baffle 1118. The horizontal pull rod 1210 drives the columnar push-pull mechanism. Rod 1213 slides backward on the inner wall of guide block 118, and the push-pull horizontal plate 1214 at the rear end of the columnar push-pull rod 1213 moves backward accordingly. The push-pull horizontal plate 1214 drives the two mold side pull plates 21 to slide backward on the inner wall of the U-shaped side guide plate 113 through two U-shaped pull frames 1215. The mold body 23 will move backward precisely to the pouring area as the mold side pull plates 21 move backward. At the same time, the backward movement of the horizontal pull rod 1210 also drives the two columnar short rods 125 to move backward through two pull blocks 126. The columnar short rods 125 drive the U-shaped pull blocks 123 to slide on the outer wall of the concave block 122. The columnar horizontal abutment rod 12 is fixed inside the U-shaped pull block 123. 7. As it moves, the elliptical slide block 128 rotates under the action of the columnar crossbar 127. The rotating side plate 129 fixed at the top of the elliptical slide block 128 slides and rotates on the top of the inner wall of the concave block 122. The rotation of the rotating side plate 129 will drive the pouring nozzle 1117 to rotate around the movable connection point at the top of its connection plate 1114 with the pouring nozzle, adjusting the spray angle of the pouring nozzle 1117 so that the nozzle is pulled downwards to the top of the mold body 23 in the pouring area. When the electric push rod 1112 is pushed to the appropriate position, the mold body 23 accurately reaches the pouring area, and the pouring nozzle 1117 is also adjusted to the appropriate spray angle. After the casting process, the heated molten metal in the casting tank 1115 is transported to the casting nozzle 1117 under pressure through the heat-insulated pipe 1116, and accurately sprayed into the mold body 23 from the casting nozzle 1117, completing the casting process. After the casting process is completed, the electric push rod 1112 is activated in reverse. After the electric push rod 1112 is activated in reverse, its push rod retracts forward. On the one hand, through the rotational connection between the rotating rod 1212 and the baffle hinge block 1119, the baffle 1118 is pushed to rotate upward around the rotation point between it and the U-shaped side guide plate 113, so that the baffle 1118 gradually closes and covers the nozzle of the casting nozzle 1117 again. On the other hand, the horizontal tie rod 1210 drives the columnar push-pull rod 1213 to slide forward on the inner wall of the guide block 118, and the mold body 23 will move forward accurately out of the casting area as the mold side pull plate 21 moves forward.

[0024] The foregoing has shown and described the basic principles, main features, and advantages of the present invention. Those skilled in the art should understand that the present invention is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of the invention.
