Description

Technical Field

[0001] The invention relates to the technical field of coal molding equipment, in particular to an ash cone mold and a die pressing device. Background Art

[0002] Coal ash fusibility refers to the physical state of the deformation, softening and flow characteristics of coal ash as the heating temperature changes under specified conditions. Coal ash fusibility is a reference indicator for evaluating whether the coal ash is easy to slag, and it is also an important quality indicator for power coal and gasification coal. The higher the melting temperature of coal ash, the higher the combustion cost; the lower the melting temperature of coal ash, the easier it is to slag in the furnace. Generally, the appropriate combustion or gasification equipment is selected based on the fusibility of coal ash, or the raw coal with a suitable softening temperature is selected based on the type of combustion and gasification equipment.

[0003] In the determination of coal ash fusibility, ash cones need to be used as samples for testing. The production process of ash cones is relatively cumbersome. First, the ash sample needs to be transferred to an ash container, moistened with a small amount of dextrin solution, and stirred evenly, and then the ash sample is placed on an ash cone mold to make an ash cone. In traditional domestic operations, ash cones are usually triangular cones, and the pressing process is manually shoveled in and squeezed with a small blade, which is not only time-consuming and labor-intensive, but also the tip and edges of the prepared ash cones are easily damaged.

[0004] Therefore, how to provide an ash cone mold with a simple structure, easy use, high production efficiency, and the ability to produce high-quality ash cones has become a technical problem that needs to be urgently solved by technical personnel in this field. Summary of the invention

[0005] In order to solve the above technical problems, the present invention provides a ash cone mold, which has a simple structure, is easy to use, has high production efficiency, and can produce high-quality ash cone samples. In addition, the present invention also provides a die pressing device including the ash cone mold, which also has the above technical effects.

DETAILED DESCRIPTION

[0021] In order to enable those skilled in the art to better understand the technical solutions in this application, this application will be described clearly and completely in conjunction with specific embodiments below. Obviously, the embodiments described are only part of the embodiments of this application, not all of them. Based on the embodiments in this application, all other embodiments obtained by ordinary technicians in this field without creative work should fall within the scope of protection of this application.

[0022] like Figures 1 to 3 As shown, the present invention provides an ash cone mold, including an upper mold 1 and a lower mold 2, the upper mold 1 and the lower mold 2 together enclose a model cavity, the upper mold 1 includes at least one feed port 11 and at least one demolding port 12, the lower mold 2 includes discharge ports 21 the same number as the demolding ports 12, and the discharge ports 21 are arranged opposite to the demolding ports 12; a molding core 3 and a core moving part are provided in the molding cavity, the molding core 3 includes a core body, and an ash cone molding cavity 31 arranged on the core body; the core moving part is used to switch the position of the core body so that the ash cone molding cavity 31 is located below the feed port 11 or below the demolding port 12.

[0023] The ash cone mold provided by the present invention is formed by an upper mold 1 and a lower mold 2 enclosing a model cavity. The upper mold 1 includes at least one feed port 11 and at least one demolding port 12. The lower mold 2 includes at least one discharge port 21. The number of the discharge ports 21 is consistent with the number of the demolding ports 12, and the discharge ports 21 are arranged opposite to the demolding ports 12. In order to facilitate the ash cone molding, a molding core 3 and a core moving part are arranged in the model cavity. The molding core 3 includes a core body and an ash cone molding cavity 31 arranged on the core body. The core moving part is used to switch the position of the core body so that the ash cone molding cavity 31 is located below the feed port 11 or below the demolding port 12. When the core molding cavity is located below the feed port 11, the ash cone mold is in a compression molding condition, and the material enters the ash cone molding cavity 31 from the feed port 11 to shape the ash cone; after the ash cone is formed, the position of the core body is switched by the core moving part so that the ash cone molding cavity 31 is located below the demoulding port 12. At this time, the ash cone mold is in a demoulding condition. Since the demoulding port 12 is arranged opposite to the discharge port 21, the ash cone can be squeezed from the demoulding port 12 to be discharged from the discharge port 21. The present invention provides a molding core 3 and a core moving part so that the ash cone mold can realize free switching between compression molding conditions and demoulding conditions, is easy to use, and has high production efficiency; and the setting of the ash cone molding cavity 31 facilitates the manufacture of high-quality ash cones with shapes and specifications that meet requirements.

[0024] Preferably, the mold core moving member comprises an elastic element 41 , one end of the elastic element 41 is connected to the inner wall of the mold cavity, and the other end is connected to the mold core body.

[0025] When the elastic element 41 is in the initial state, the ash cone forming cavity 31 is located below the feed port 11 (or the demolding port 12). Depending on the required working conditions, the elastic element 41 can be compressed (or stretched) by pushing (or pulling) the core body to move the ash cone forming cavity 31 to below the demolding port 12 (or the feed port 11).

[0026] As an embodiment of the present invention, the elastic element 41 may be a coil spring.

[0027] When the coil spring is in the initial state, the ash cone forming cavity 31 is located below the feed port 11. When the material enters the ash cone forming cavity 31 and completes forming, the core mold body is pushed to compress the coil spring, and the ash cone forming cavity 31 is moved to below the demolding port 12. The ash cone is squeezed to be ejected from the discharge port 21. After demolding is completed, the thrust applied to the core mold body is removed, the coil spring is reset, and the core mold body is moved back to below the feed port 11 under the push of the coil spring.

[0028] Preferably, an operating rod is provided at one end of the mold core body, and the operating rod is arranged at one end of the mold core body away from the elastic element 41. The arrangement of the operating rod facilitates pushing (or pulling) the mold core body by grasping the operating rod.

[0029] Preferably, a core pusher 5 is further included. The core pusher 5 is arranged on a side of the core body away from the elastic element 41 . The core pusher 5 is used to push the core body to move so as to deform the elastic element 41 .

[0030] As one embodiment of the present invention, the core pusher 5 can be a push cylinder and a push plate connected to the output end of the push cylinder. When the position of the ash cone forming cavity 31 needs to be switched, the push cylinder drives the push plate to move, and the push plate then transmits the thrust to the operating rod (when there is no operating rod, the push plate directly transmits the thrust to the core body), thereby pushing the core body to move and moving the ash cone forming cavity 31 to the target position.

[0031] In order to prevent the core body from shifting during movement, preferably, a guide block 42 is provided on the core body, and a guide groove 43 matching the guide block 42 is provided in the mold cavity; the guide groove 43 is arranged along the moving direction of the core body.

[0032] Furthermore, through the cooperation between the guide block 42 and the guide groove 43, the moving position of the core body can be limited, and the feed port 11 and the demolding port 12 are correspondingly set at the two ends of the guide groove 43, which can ensure that in the initial position, the core body can be stably located below the feed port 11 under the thrust of the elastic element 41 and the limiting action of the guide groove 43; after the ash cone is formed, the core body is pushed to compress the elastic element 41, and the ash cone forming cavity 31 carrying the formed ash cone moves toward the demolding port 12. Finally, the core body is stably located below the demolding port 12 under the external thrust and the limiting action of the guide groove 43.

[0033] Preferably, the upper mold 1 includes a plurality of feed ports 11 and a plurality of demoulding ports 12, and the lower mold 2 includes a plurality of discharge ports 21, wherein the number of the demoulding ports 12 is the same as that of the discharge ports 21, and the demoulding ports 12 are arranged opposite to the discharge ports 21. In this way, the ash cone mold provided by the embodiment of the present invention can complete the processing and forming of multiple ash cones at the same time.

[0034] In addition, the present invention also provides a die pressing device, including a frame 6 and any one of the above-mentioned ash cone molds, the ash cone mold is arranged on the frame 6, and a die pressing mechanism 7 is also arranged above the ash cone mold, the die pressing mechanism 7 includes a die push rod 71, and a die driving member 72 for driving the die push rod 71 to reciprocate, and the die push rod 71 is arranged directly above the feed port 11.

[0035] When the ash cone mold is in the pressing state, the ash cone forming cavity 31 is located below the feed port 11, and the material enters the ash cone forming cavity 31 from the feed port 11. Then, the pressing mold push rod 71, driven by the pressing mold driving member 72, reciprocates in the vertical direction, so that the material is repeatedly squeezed in the ash cone forming cavity 31 to form a ash cone.

[0036] Preferably, a demoulding mechanism 8 is further provided above the ash cone mold. The demoulding mechanism 8 includes a demoulding ejector pin 81 and a demoulding driving member 82 for driving the demoulding ejector pin 81 to reciprocate. The demoulding ejector pin 81 is arranged directly above the demoulding port 12 .

[0037] When the ash cone mold is in the demolding condition, the ash cone forming cavity 31 is located below the demolding port 12. Under the action of the demolding drive member 82, the demolding push rod 81 reciprocates in the vertical direction, enters the ash cone forming cavity 31 from the demolding port 12, and applies pressure to the ash cone in the ash cone forming cavity 31, so that the ash cone is ejected from the discharge port 21.

[0038] Preferably, the demoulding driving member 82 is a cam mechanism, and the demoulding ejector rod 81 is drivingly connected to the output end of the cam mechanism.

[0039] As one embodiment of the present invention, the die pressing mechanism 7 includes a die pressing driving member 72, a fixed plate connected to the output end of the die pressing driving member 72, and a die pressing push rod 71 installed on the fixed plate. During operation, the fixed plate reciprocates in the vertical direction along with the output end of the die pressing driving member 72, thereby driving the die pressing push rod 71 to also reciprocate in the vertical direction. Furthermore, the demolding mechanism 8 can also be installed on the fixed plate and move with the fixed plate.

[0040] Preferably, an ash cone supporting plate 9 is provided below the ash cone mold, and the ash cone supporting plate 9 is used to receive the processed ash cone.

[0041] Preferably, a rotary drive mechanism 91 is provided below the ash cone support plate 9, and the rotary drive mechanism 91 is used to drive the ash cone support plate 9 to rotate. The rotary drive mechanism 91 drives the ash cone support plate 9 to rotate, thereby preventing the ash cones from piling up on the ash cone support plate 9.

[0042] Preferably, the rotary drive mechanism 91 is a graduated rotary mechanism, which can drive the ash cone support plate 9 to rotate evenly and evenly, so that the ash cones are evenly distributed on the ash cone support plate 9 at equal intervals.

[0043] Preferably, the ash cone forming cavity 31 is a cylindrical cavity. The cylindrical ash cone has a stable structure and is not easily damaged.
