Description

Technical Field

[0001] The utility model relates to the technical field of metal ingot making molds, in particular to a metal ingot making mold with a preheating function. Background Art

[0002] Metal ingot production is the process of melting and then casting metal into specific shapes and specifications. It is commonly used in the production of various metal materials, such as aluminum ingots, copper ingots, and steel ingots. The ingot production process includes steps such as metal melting, refining, mold casting, and cooling. During the casting process, mold preheating is crucial. Preheating the mold prevents the molten metal from rapidly cooling upon contact with the cold mold, thereby avoiding defects such as pores, cracks, and stress concentrations, and improving the ingot quality and surface finish. Furthermore, preheating the mold reduces temperature gradients, extending mold life and ensuring a stable and efficient production process. Therefore, mold preheating is an indispensable step in metal ingot production.

[0003] Traditional metal ingot molds are used by first pouring molten metal into a preheated mold, allowing it to gradually cool and solidify. This process ensures even distribution of the metal to avoid air bubbles and irregular solidification. After the metal has completely cooled and solidified, the formed ingot is removed and cleaned and inspected as necessary. This crucial step in ensuring ingot quality contributes to the production of high-quality, defect-free ingots.

[0004] Traditional metal ingot molds are usually made of materials such as steel or cast iron. They do not have internal heating elements and lack effective heating and temperature control mechanisms, making the preheating process complicated and difficult to implement. The molten metal cools rapidly when it contacts the cold mold, which easily produces pores, cracks and internal stress, affecting the ingot quality and mechanical properties. Utility Model Content

[0005] In order to make up for the above shortcomings, the utility model provides a metal ingot mold with a preheating function, which aims to improve the problem that traditional metal ingot molds lack effective heating and temperature control mechanisms, so that the molten metal cools down rapidly when it contacts the cold mold, which is prone to produce pores, cracks and internal stress, affecting the ingot quality and mechanical properties.

[0006] To achieve the above-mentioned purpose, the utility model provides the following technical solution: a metal ingot mold with a preheating function, comprising a lower mold, the bottom of the lower mold is fixedly connected to a base, the interior of the base is fixedly connected to an oil pipe, one end of the oil pipe is fixedly connected to an input pipe, the other end of the oil pipe is threadedly connected to a fixed cover, an interface is provided in the middle of the oil pipe, the outer wall of the oil pipe is fixedly connected to a heat sink, the outer wall of the heat sink is fixedly connected to the interior of the lower mold, the interior of the base is threadedly connected to a sealing cover, an upper mold is provided above the lower mold, the interior of the upper mold is slidably connected to a sealing strip, the lower surface of the sealing strip is affixed to the upper surface of the base, a pushing component is provided inside the sealing strip, and the pushing component is used to push the sealing strip to fit tightly with the base.

[0007] Furthermore, the pushing assembly includes a telescopic rod 1, one end of which is fixedly connected to the inside of the sealing strip, and the other end of the sealing strip is fixedly connected to the inside of the upper mold. The outer wall of the telescopic rod 1 is provided with a spring 1, one end of which is fixedly connected to the inside of the upper mold, and the other end of the spring 1 is fixedly connected to the inside of the sealing strip.

[0008] Furthermore, a handle is fixedly connected to the outer wall of the upper mold, and a positioning column is fixedly connected to the lower surface of the upper mold.

[0009] Furthermore, the outer wall of the positioning column is slidably connected to the inside of the base, the outer wall of the lower mold is fixedly connected to a first fixing plate, and the outer wall of the base is fixedly connected to a second fixing plate.

[0010] Furthermore, a positioning sleeve is fixedly connected to the interior of the first fixing plate, and an outer wall of the positioning sleeve is slidably connected to the interior of the second fixing plate.

[0011] Furthermore, the inner wall of the positioning sleeve is fixedly connected to the bearing 1, and the inner wall of the bearing 1 is fixedly connected to the screw.

[0013] Furthermore, a second telescopic rod is fixedly connected to the interior of the triangular clamping block, a second spring is sleeved on the outer wall of the second telescopic rod, and both ends of the second spring are fixedly connected to the interior of the triangular clamping block.

[0014] The utility model has the following beneficial effects:

[0015] 1. In the utility model, first, hot oil is delivered to the oil delivery pipe through the input pipe, and then the mold is evenly heated in conjunction with the fixed cover, the interface and the heat sink. Then the sealing cover is opened for stable heat dissipation. Finally, the mold, the sealing strip, the telescopic rod and the spring are coordinated to perform efficient sealing. This solves the problem that the mold lacks an effective heating and temperature control mechanism, which easily generates pores, cracks and internal stress, affecting the quality and mechanical properties of the ingot. Preheating and smooth cooling are achieved, reducing the drastic changes between high and low temperatures of the mold, reducing thermal fatigue and thermal stress, and extending the service life of the mold. At the same time, efficient sealing can prevent the leakage of harmful gases and smoke, and improve the working environment.

[0027] Reference Figure 1 - Figure 5 The utility model provides an embodiment: a metal ingot mold with a preheating function, comprising a lower mold 1, the bottom of the lower mold 1 is fixedly connected to a base 2, the interior of the base 2 is fixedly connected to an oil pipe 3, one end of the oil pipe 3 is fixedly connected to an input pipe 4, the other end of the oil pipe 3 is threadedly connected to a fixed cover 5, an interface 6 is provided in the middle of the oil pipe 3, the outer wall of the oil pipe 3 is fixedly connected to a heat sink 7, the outer wall of the heat sink 7 is fixedly connected to the interior of the lower mold 1, the interior of the base 2 is threadedly connected to a sealing cover 8, an upper mold 9 is provided above the lower mold 1, and the upper mold 9 The interior of the sealing strip 10 is slidably connected thereto, the lower surface of the sealing strip 10 is fitted to the upper surface of the base 2, a pushing assembly is provided inside the sealing strip 10, the pushing assembly is used to push the sealing strip 10 to fit tightly against the base 2, the pushing assembly includes a telescopic rod 11, one end of the telescopic rod 11 is fixedly connected to the interior of the sealing strip 10, the other end of the sealing strip 10 is fixedly connected to the interior of the upper mold 9, the outer wall of the telescopic rod 11 is provided with a spring 12, one end of the spring 12 is fixedly connected to the interior of the upper mold 9, and the other end of the spring 12 is fixedly connected to the interior of the sealing strip 10;

[0028] Specifically, before using the mold, first, the hot oil is transported to the inside of the oil pipe 3 through the input pipe 4, and then the oil is spread throughout the inside of the lower mold 1 through the oil pipe 3, and then the heat is evenly distributed inside the lower mold 1 through the oil pipe 3 to fully preheat it. Finally, the fixed cover 5 is driven to rotate on the outer wall of the oil pipe 3 to open one end of the oil pipe 3 so that the oil after heat exchange can be discharged. Then, the upper mold 9 can be covered on the top of the lower mold 1 through the positioning column 13, and the sealing strip 10 is fit to the upper surface of the lower mold 1. At this time, the sealing strip 10 is supported by the lower mold 1 to slide on the inner wall of the upper mold 9 and pressure is applied to the spring 12 to shrink the spring 12. Then, the thrust generated by the contraction of the spring 12 pushes the sealing strip 10 to fit tightly with the lower mold 1, and the ingot is placed to allow the heat to overflow. After the ingot is made, the sealing cover 8 can be driven to rotate so that the sealing cover 8 opens the base 2, and then the heat is evenly and quickly dissipated through the channel inside the base 2.

[0029] Reference Figure 1 、 Figure 6 and Figure 7 The outer wall of the upper mold 9 is fixedly connected to a handle 14, the lower surface of the upper mold 9 is fixedly connected to a positioning column 13, the outer wall of the positioning column 13 is slidably connected to the inside of the base 2, the outer wall of the lower mold 1 is fixedly connected to a fixing plate 15, the outer wall of the base 2 is fixedly connected to a fixing plate 2 16, the interior of the fixing plate 15 is fixedly connected with a positioning sleeve 17, the outer wall of the positioning sleeve 17 is slidably connected to the interior of the fixing plate 2 16, the inner wall of the positioning sleeve 17 is fixedly connected to a bearing 18, the inner wall of the bearing 18 is fixedly connected to a screw 19, the outer wall of the screw 19 is threadedly connected to a trapezoidal push block 20, the outer wall of the trapezoidal push block 20 is slidably connected to a triangular clamping block 21, the outer wall of the triangular clamping block 21 is slidably connected to the interior of the positioning sleeve 17 and the fixing plate 2 16, the interior of the triangular clamping block 21 is fixedly connected to a telescopic rod 22, the outer wall sleeve of the telescopic rod 22 is provided with a spring 23, and both ends of the spring 23 are fixedly connected to the inside of the triangular clamping block 21;

[0030] Specifically, when the upper mold 9 and the lower mold 1 are fitted together, the positioning sleeve 17 will be driven to move to the inside of the fixing plate 2 16 through the fixing plate 15, and then the screw 19 will be driven to cooperate with the bearing 18 to drive the screw 19 to rotate inside the positioning sleeve 17. Due to the threaded relationship between the screw 19 and the trapezoidal push block 20, the trapezoidal push block 20 will slide inside the positioning sleeve 17 as the screw 19 rotates, thereby pushing the two triangular blocks 21 to slide inside the positioning sleeve 17 and the fixing plate 1 15 through the inclined surface of the trapezoidal push block 20. The second spring 23 is moved to realize the connection between the lower mold 1 and the upper mold 9, and at the same time, the spring 23 is stretched. When the triangular clamping block 21 moves to the inside of the fixed plate 15, due to the setting of the inclined surface of the triangular clamping block 21, the distance between the lower mold 1 and the upper mold 9 is gradually reduced, and finally a completely fitting connection is achieved. When disassembling, it is only necessary to rotate the screw 19 in the opposite direction. At this time, the second spring 23 is no longer subjected to force and rebounds, thereby pulling the triangular clamping block 21 back to the inside of the positioning sleeve 17, thereby realizing the installation and disassembly of the lower mold 1 and the upper mold 9.

[0031] Working principle: When a metal ingot-making mold with a preheating function is needed, first send the hot oil into the oil pipe 3, and the hot oil is distributed to the inside of the lower mold 1 through the oil pipe 3 to achieve uniform preheating. After preheating is completed, rotate the fixed cover 5, open one end of the oil pipe 3, and discharge the oil that has exchanged heat. Then, with the help of the positioning column 13, the upper mold 9 is accurately placed on the lower mold 1, and the sealing strip 10 is supported by the lower mold 1 to slide on the inner wall of the upper mold 9, compressing the spring 12. The contraction of the spring 12 pushes the sealing strip 10 to fit closely with the lower mold 1 to prevent heat loss. After the ingot-making process is completed, rotate the sealing cover 8, open the base 2, and dissipate heat quickly through the internal channel of the base 2. At the same time, the upper mold 9 and the lower mold 1 are combined. When closed, the fixing plate 15 pushes the positioning sleeve 17 into the fixing plate 2 16, and then the driving screw 19 rotates in the positioning sleeve 17. Due to the threaded fit between the screw 19 and the trapezoidal push block 20, the trapezoidal push block 20 slides in the positioning sleeve 17 and pushes the triangular clamping block 21 to move in the positioning sleeve 17 and the fixing plate 1 15 through its inclined surface, thereby realizing a close connection between the upper mold 9 and the lower mold 1. At the same time, the spring 2 23 is stretched, and the inclined surface design of the triangular clamping block 21 gradually reduces the distance between the upper mold 9 and the lower mold 1 until they are fully fitted. When disassembling, the screw 19 is rotated in the opposite direction, and the spring 2 23 rebounds to pull the triangular clamping block 21 back into the positioning sleeve 17, completing the installation and disassembly of the mold, ensuring the accuracy of the mold connection and the convenience of operation.

[0032] Finally, it should be noted that the above are only preferred embodiments of the present invention and are not intended to limit the present invention.
