Description

Technical Field

[0001] This utility model relates to the field of crucible extrusion molding technology, and in particular to a crucible extrusion molding die capable of rapid cooling. Background Technology

[0002] Currently, crucible forming methods mainly include vibration molding, extrusion molding, and compression molding. Among these, compression molding has advantages such as high efficiency, simple operation, large production capacity, and low energy consumption, and is therefore widely used. The molding die often plays a crucial role in the molding process; a good die can achieve twice the result with half the effort.

[0003] Chinese patent document CN210939799U discloses a crucible forming mold, belonging to the field of crucible forming technology. This invention includes an inner mold, with a fixed ring and a movable ring sequentially fitted around its outer circumference from top to bottom. The fixed ring has a mounting hole at its bottom that penetrates the thickness of its bottom. The movable ring includes a ring body fitted around the outer circumference of the inner mold, with a guide rod provided on the ring body. The guide rod passes through the mounting hole, and an anti-detachment component is provided at the end of the guide rod away from the ring body to prevent it from falling out of the mounting hole. The purpose of this invention is to overcome the shortcomings of existing crucible forming molds, such as difficulty in demolding, and to provide a crucible forming mold that solves problems such as difficulty in demolding during the forming process, easy deformation of the opening, and cracking, thereby improving the yield of the molded product and thus improving the quality of the green body.

[0004] However, in actual use, the device creates a vacuum inside the crucible after molding, which can easily damage the crucible during demolding and reduce the molding rate. In addition, the device cannot cool the crucible quickly, resulting in relatively low working efficiency. Utility Model Content

[0005] The main purpose of this invention is to provide a crucible extrusion molding die that can be cooled quickly, which can effectively solve the problems of relatively low crucible forming rate and working efficiency.

[0006] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

[0007] A crucible extrusion molding die capable of rapid cooling includes an outer die, a square platform-shaped groove on the right side of the outer die, an inner die on the inner surface of the outer die, ventilation pipes fixed at both the upper and lower ends of the outer die, and a water inlet pipe fixed at the upper end of the outer die.

[0008] Preferably, the inner mold includes two mounting brackets, and a square-shaped guide groove is fixed between the two mounting brackets. The inner mold body is fixed to the left end of the square-shaped guide groove. A through J-shaped pipe I is opened in the interior of the square-shaped guide groove and the inner mold body. A through J-shaped pipe II is also symmetrically opened in the interior of the square-shaped guide groove and the inner mold body. A sealing component is provided on the left side of the inner surface of both the first J-shaped pipe and the second J-shaped pipe.

[0009] Preferably, the sealing assembly includes a conical groove formed on the left side of the pipe cavity, and a plurality of spring telescopic rods are fixed to the side wall of the conical groove, with a conical sealing gasket fixed to the output end of the plurality of spring telescopic rods.

[0010] Preferably, the second J-shaped pipe is connected to the interior of the ventilation pipe, and the first J-shaped pipe is connected to the interior of the water inlet pipe.

[0011] Preferably, when the spring telescopic rod is in its natural state, the conical sealing gasket does not seal the conical groove.

[0012] Compared with the prior art, the present invention has the following beneficial effects:

[0013] 1. This crucible extrusion molding device adopts an internal mold design. Through the cooperation between the internal mold and the J-shaped pipe, cool water can be sprayed into the inside of the crucible after molding to facilitate the cooling and molding of the crucible, facilitate the demolding of the crucible, and improve the working efficiency of the device.

[0014] 2. This crucible extrusion molding device adopts a sealing component design. Through the cooperation between the spring telescopic rod and the conical sealing gasket, air can be injected into the crucible when it moves to the left, preventing a vacuum from forming inside the crucible and thus preventing deformation of the crucible after molding, thereby improving the yield of crucibles.

[0021] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0022] like Figure 1 and Figure 2 As shown, a crucible extrusion molding die capable of rapid cooling includes an outer mold 1 with openings on both sides. A square-shaped groove 2 is provided on the right side of the outer mold 1. During crucible molding, material is fed from the right side of the outer mold 1. Since the material has a low density during transport, when the material is squeezed into the square-shaped groove 2, the density of the material entering the outer mold 1 can be increased through the inclined side wall, so that the crucible after molding is more compact and prevents the side wall of the molded crucible from becoming loose and easily collapsing. An inner mold 4 is provided on the inner surface of the outer mold 1. Ventilation pipes 5 are fixed at both the upper and lower ends of the outer mold 1, and a water inlet pipe 6 is also fixed at the upper end of the outer mold 1.

[0023] like Figure 2 - Figure 4 As shown, the inner mold 4 includes two mounting brackets 41. The mounting brackets 41 are used to mount the truncated square guide groove 42, and the right end of the mounting bracket 41 has a ramp to reduce the resistance caused by the right side of the mounting bracket 41 to the material, allowing the material to enter the forming cavity more smoothly. The truncated square guide groove 42 is fixed between the two mounting brackets 41. Since the sidewalls of the truncated square guide groove 42 and the truncated square groove 2 are both inclined, the pressure inside the forming cavity can be increased, making the formed crucible more compact and preventing it from easily collapsing after forming. The left end of the truncated square guide groove 42 is fixed to the inner mold body 43, which is located inside the outer mold 1. The gap between the inner mold body 43 and the outer mold 1 is the forming cavity. Figure 2 It can be seen that the left side of the inner mold body 43 is located inside the outer mold 1, and the gap between the left side of the inner mold body 43 and the left side of the outer mold 1 is the forming cavity of the crucible bottom.

[0024] In addition, the square-shaped guide groove 42 and the inner mold body 43 are both provided with a through J-shaped pipe 44. The J-shaped pipe 44 is used to spray cool water into the inner cavity of the formed crucible to accelerate the cooling and forming of the crucible, facilitate the demolding of the crucible, and improve the working efficiency of the device. The square-shaped guide groove 42 and the inner mold body 43 are also symmetrically provided with through J-shaped pipes 48. Due to the design of the J-shaped pipes 48, negative pressure can be prevented from being generated in the inner cavity of the formed crucible, which would cause the formed crucible to break. Sealing components 7 are provided on the left side of the inner surface of both the J-shaped pipes 44 and 48.

[0025] Furthermore, to accelerate crucible cooling during use and prevent negative pressure from forming inside the crucible, to prevent multiple grooves or protrusions from appearing at the bottom of the crucible after molding, and to prevent material from clogging J-shaped pipe 44 and J-shaped pipe 48, such as... Figure 5 As shown, the sealing assembly 7 includes a conical groove 71 opened on the left side of the inner cavity of the pipe. Multiple spring telescopic rods 72 are fixed to the side wall of the conical groove 71. The output ends of the multiple spring telescopic rods 72 are jointly fixed with a conical sealing gasket 73 for sealing the conical groove 71. When the conical groove 71 seals the conical sealing gasket 73, water in the J-shaped pipe 44 will not spray into the crucible and air cannot enter the crucible. At the same time, due to the design of multiple conical sealing gaskets 73, materials can be prevented from entering the J-shaped pipe 44 and the J-shaped pipe 48 to ensure the stable operation of the device.

[0026] When the spring telescopic rod 72 is in its natural state, the conical sealing gasket 73 does not seal the conical groove 71, which can prevent material from entering the J-shaped pipe 44 and J-shaped pipe 48 when the bottom of the crucible is being formed, making the device more stable during use.

[0027] J-shaped pipe 48 is connected to the interior of ventilation pipe 5, and J-shaped pipe 44 is connected to the interior of water inlet pipe 6, so as to facilitate the spraying of cool water and the injection of air into the formed crucible during use.

[0028] The specific implementation of this embodiment is as follows: When the device is in use, the left opening of the outer mold 1 is first blocked by a baffle. Then, the material to be used is injected into the outer mold 1 and the square-shaped groove 2. A large amount of material will be filled in the gap between the left side of the inner mold body 43 and the left side of the outer mold 1. After the material cools and solidifies, it forms the bottom of the crucible. Due to the blockage of the baffle and the high pressure of the material, multiple spring telescopic rods 72 will contract, thereby allowing the conical sealing gasket 73 to seal the pipe, which can prevent the material from entering the J-shaped pipe 1 44 and J-shaped pipe 2 48, thus affecting the molding of the crucible. When the bottom of the crucible moves to the left, due to the elastic design of the spring telescopic rod 72, the output end of the spring telescopic rod 72 extends, thereby preventing the conical sealing gasket 73 from sealing the conical groove 71.

[0029] Then water is injected into the water inlet pipe 6. The water will be sprayed to the bottom of the crucible through the J-shaped pipe 44. At the same time, due to the conical design of the conical sealing gasket 73, the spray direction of the water can be changed, so that the water is sprayed to the side wall of the crucible to facilitate the molding of the crucible.

[0030] Meanwhile, when the formed crucible moves to the left, no air enters the crucible and a vacuum is formed between the crucible and the inner mold body 43 due to the design of the inner mold body 43, causing the crucible to deform. At the same time, due to the design of the sealing component 7, air can enter the crucible through the J-shaped pipe 48 when the crucible moves to the left, so as to prevent the crucible from deforming when it moves to the left.

[0031] Once the crucible reaches the set length, it can be cut using a cutting tool. Then, the next crucible can be formed by using a baffle to block out the obstruction.

[0032] It should be noted that the specific installation methods, circuit connection methods, and control methods of the mold, spring telescopic rod 72, and conical sealing gasket 73 in this utility model are all conventional designs, and will not be described in detail in this utility model.

[0033] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claims. The scope of protection of this utility model is defined by the appended claims and their equivalents.
