Description

Technical Field

[0001] This utility model relates to the field of brick forming molds, and more specifically, to a magnesium-carbon brick forming mold that automatically cleans up residual material. Background Technology

[0002] The molding and production of magnesia-carbon bricks typically relies on molds for pressing. During the molding process, the magnesia-carbon brick raw material is pressed under high pressure within the mold cavity to form a blank. The basic working principle is as follows: When pressing magnesia-carbon bricks, the raw material is first poured into the mold cavity. Then, the sub-mold of the molding mold presses down, and with the cooperation of the mother mold, the raw material is pressed into shape within the mold cavity. The sub-mold then moves upwards to reset and detaches from the mold cavity. Simultaneously, the mother mold inside the mold cavity moves upwards, pushing the pressed magnesia-carbon brick blank upwards to the outside of the mold cavity. At this point, a cylinder pushing mechanism on the outside pushes the magnesia-carbon brick blank towards the pusher side plate, allowing it to smoothly reach the conveyor belt on the pusher side plate and be transported away.

[0003] Based on the above, although existing magnesia-carbon brick forming molds have many advantages, the inventors have also found the following shortcomings in actual use: For example, when pouring magnesia-carbon brick raw materials into the mold cavity, some inevitably spills onto the edge of the lower mold frame and the top edge of the pusher side plate. Or when the sub-mold presses down to perform pressing, the air pressure inside the mold cavity overflows along the contact gap between the sub-mold edge and the inner wall of the mold cavity, inevitably carrying some magnesia-carbon brick raw materials to the edge of the lower mold frame and the top edge of the pusher side plate. Therefore, when the cylinder pushes the magnesia-carbon brick blank to move onto the conveyor belt, it inevitably comes into contact with the top edge of the pusher side plate, causing the magnesia-carbon brick raw materials to easily stick to the bottom of the magnesia-carbon brick blank, thus affecting the surface smoothness of the magnesia-carbon brick blank in the later sintering. Therefore, we have proposed a magnesia-carbon brick forming mold with automatic cleaning of residual material to solve the above-mentioned problems. Utility Model Content

[0004] 1. Technical problems to be solved To address the problems existing in the prior art, the purpose of this utility model is to provide an automatic residual material cleaning magnesia-carbon brick forming mold. It utilizes a rubber scraper mechanism driven by a rack and gear on the outer side of the pusher side plate. Each time the upper mold base pushes down the sub-mold body, the contact and compression of the positioning guide rod, push rod, connecting plate, steel cable, and winch drive the rubber scraper to scrape from one side of the top of the pusher side plate to the other. When the upper mold base finishes pressing down and resets, the springback drives the rack and gear to the reset state, completing the reset scraping motion of the rubber scraper from one side of the top of the pusher side plate to the other. This thoroughly cleans up any magnesia-carbon brick raw material splashed or spilled on the top of the pusher side plate, preventing the bottom of the formed magnesia-carbon brick blank from contacting and adhering to the magnesia-carbon brick raw material as it moves onto the conveyor belt from the top of the pusher side plate, thus avoiding any impact on the surface smoothness of the magnesia-carbon brick blank.

[0005] 2. Technical Solution To solve the above problems, the present invention adopts the following technical solution.

One end of the steel cable is connected to the inside of the opening through the guide pulley. A mounting base is fixedly welded to one side of the top surface of the rack, and a clamp is fixedly installed on the mounting base. A rubber scraper is fixedly clamped at the bottom of the clamp. The bottom edge of the rubber scraper is on the same horizontal plane as the top surface of the pusher side plate, and the top surface of the pusher side plate is higher than the top surface of the rack.

[0007] Furthermore, a groove is provided on one side of the rack, and a slide bar is slidably connected inside the groove.

[0011] 3. Beneficial Effects Compared with existing technologies, the advantages of this utility model are: This solution utilizes a rubber scraper mechanism driven by a rack and gear on the outer side of the pusher side plate. Each time the upper mold base presses down on the sub-mold body, the contact and compression of the positioning guide rod, push rod, connecting plate, steel cable, and winch drive the rubber scraper from one side of the top of the pusher side plate to the other. When the upper mold base finishes pressing down and resets, the springback drives the rack and gear to the reset state, completing the rubber scraper's reset scraping motion from one side of the top of the pusher side plate to the other. This thoroughly cleans up any magnesia-carbon brick raw material splashed or spilled on the top of the pusher side plate, preventing the bottom of the formed magnesia-carbon brick blank from contacting and adhering to the raw material as it moves onto the conveyor belt from the top of the pusher side plate, thus avoiding any impact on the surface smoothness of the magnesia-carbon brick blank.

A rubber scraper 12 is fixedly clamped at the bottom of the clamp 11.

A groove 301 is provided on one side of the rack 3, and a slide bar 13 is slidably connected inside the groove 301. The slide bar 13 is fixedly installed on the side wall of the pusher side plate 201 by screws. A connecting post 302 is fixedly welded to one end of the rack 3. A ring seat is fixedly welded to one side of the pusher side plate 201 at the position of the connecting post 302. The ring seat and the connecting post 302 are connected by a tension spring 14.

The gear 4 is fixedly installed on the rotating shaft 16, and the winch 5 is fixedly installed at the end of the rotating shaft 16 by bolts. A sub-mold body 17 is fixedly installed at the bottom of the upper mold base 1.

The length of the positioning guide rod 19 is less than the height of the through hole 202, and the push rod 7 and the through hole 202 are respectively provided with anti-detachment edge 1 701 and anti-detachment edge 2021.

[0016] The working principle of this type of magnesia-carbon brick molding die that automatically cleans up residual material is as follows: First, the lower mold frame 2 is installed on the hydraulic brick machine using a bracket. Then, the upper mold base 1, with the sub-mold body 17 installed at the bottom, is installed on the hydraulic rod at the top of the hydraulic brick machine. Finally, the mother mold body 18 is installed on the hydraulic rod at the bottom of the hydraulic brick machine, and the mother mold body 18 is fitted inside the lower mold frame 2. Then, one end of the conveyor belt is close to the outside of the pusher side plate 201, and the cylinder is set on the outside of the lower mold frame 2 on the opposite side of the pusher side plate 201, so that the extension rod of the cylinder can push the magnesia-carbon brick blank at the top of the lower mold frame 2 over the top of the pusher side plate 201 and onto the conveyor belt (the specific installation structure and working principle of the hydraulic brick machine, conveyor belt and cylinder are known and publicly available technologies, so they will not be described in detail here). During brick making, the magnesia-carbon brick forming material is first added into the hollow cavity of the lower mold frame 2. Then, the hydraulic rod at the top of the hydraulic brick machine pushes the upper mold base 1 and the sub-mold body 17 downward, so that the sub-mold body 17 is pressed into the hollow cavity of the lower mold frame 2, and the magnesia-carbon brick forming material inside the hollow mold cavity is squeezed to obtain a complete magnesia-carbon brick blank. During the downward movement of the upper mold base 1, the four positioning guide rods 19 are inserted into the corresponding through holes 202 and push the two push rods 7 downward. Then, the steel cable 9 is pulled through the connection of the connecting plate 8, causing the winch 5 and gear 4 to rotate. Then, through the connection of the rack 3, the rubber scraper 12 is driven to scrape from one side of the top of the pusher side plate 201 to the other side. At the same time, the movement of the rack 3 also pulls the tension spring 14, which facilitates the reset of the rack 3 later. At this time, the extrusion action of the sub-mold body 17 is completed, that is, the mold closing action is completed. Then, the mold opening action is performed. The hydraulic rod at the top of the hydraulic brick machine first drives the upper mold base 1 and the sub-mold body 17 to move upward and reset, causing the sub-mold body 17 to detach from the hollow mold cavity of the lower mold frame 2. During the upward reset of the upper mold base 1, since the push rod 7 loses the squeezing of the positioning guide rod 19, the reset spring 20 pushes the two push rods 7 and the connecting plate 8 upward to the reset state. At the same time, the tension spring 14 pulls the rack 3 to move in the opposite direction and reset, and drives the gear 4 and the winch 5 to rotate in the opposite direction to wind up the steel cable 9. During the reverse reset of the rack 3, the rubber scraper 12 is driven to scrape from the other side of the top of the pusher side plate 201 to one side, thus completing the reset action. At this time, the secondary scraping action of the top of the pusher side plate 201 can be achieved to prevent the spilled and splashed magnesium carbon brick forming raw materials from remaining on the top of the pusher side plate 201. Finally, the hydraulic rod at the bottom of the hydraulic brick machine pushes the mother mold 18 upward, pushing the magnesia-carbon brick blank upward to the top of the lower mold frame 2. At this time, the cylinder can push the magnesia-carbon brick blank onto the conveyor belt through the top of the pusher side plate 201, so that it can be easily transported to the sintering process for sintering.

[0017] Example 2: In view of the above embodiment 1, further description is provided, see reference. Figures 5-7 The design of the bottom edge of the rubber scraper 12 being on the same horizontal plane as the top surface of the pusher side plate 201 facilitates the rubber scraper 12 to be driven to scrape the top surface of the pusher side plate 201 repeatedly through the connection of the mounting base 10 and the clamp 11 when the rack 3 moves back and forth. This avoids the magnesia-carbon brick molding raw material being splashed or splashed and left on the top of the pusher side plate 201, causing the magnesia-carbon brick blank to stick to its bottom when it is pushed. The structural design of the top surface of the pusher side plate 201 being higher than the top surface of the rack 3 allows the magnesia-carbon brick blank to directly contact the top surface of the pusher side plate 201 and the top surface of the conveyor belt when it is pushed, thus preventing the magnesia-carbon brick forming raw materials spilled or splashed from the top surface of the rack 3 from contacting the bottom of the magnesia-carbon brick blank.

[0018] The above description is merely a preferred embodiment of this utility model; however, the protection scope of this utility model is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the technical scope disclosed in this utility model, based on the technical solution and its improved concept, should be included within the protection scope of this utility model.
