Description

Technical Field

[0001] This utility model relates to the field of casting sand core technology, specifically a casting sand core raw material mixing mechanism. Background Technology

[0002] Core making is a casting process that involves mixing core sand materials and forming sand cores using a core box. It is divided into two major systems: manual core making and machine core making. Core sand consists of casting sand, binder, and additives, and must meet technical requirements such as high strength and permeability. Traditional processes use materials such as clay sand and oil sand, while modern industry widely uses resin-coated sand combined with mechanized technologies such as hot core box method and cold core box method. This process directly affects the forming quality of the internal structure of the casting and has been deeply applied in mass production in fields such as automobile manufacturing.

[0003] For example, patent document CN 222790546 U discloses a casting sand core raw material mixing mechanism, including a mixing tank; the mixing tank is used to support the mechanism components, and the mixing tank is equipped with a mixing rack cleaning component, a lifting adjustment component, and a mixing component; this utility model relates to the field of sand core manufacturing technology and has the following beneficial effects: the mixing rack cleaning component can be set around the mixing rack, and high-pressure airflow is used to blow off the raw material adhering to the mixing rack. At the same time, the lifting mixing component can drive all parts of the mixing rack to pass through the cleaning area for cleaning, thereby effectively blowing off the raw material on the mixing rack, keeping the mixing rack clean after each mixing operation, preventing dirt and grime from accumulating on the mixing rack, and facilitating the maintenance of the mechanism.

[0004] However, in actual use, due to its own structural limitations, this structure can only perform simple mixing operations of casting sand core materials. During the mixing process, the casting sand core materials cannot flow fully from top to bottom, which easily leads to uneven mixing of materials. At the same time, the equipment cannot perform more thorough and synchronous mixing operations of casting sand core materials from top to bottom, which cannot meet the needs of daily use. Therefore, it is urgent to design a casting sand core material mixing mechanism to solve the above problems. Utility Model Content

[0005] The purpose of this utility model is to provide a casting sand core material mixing mechanism to solve the problem mentioned in the background art. In actual use, the existing structure is limited by its own structure and can only perform simple stirring and mixing operations of casting sand core materials. During the mixing process, the casting sand core materials cannot be fully flowed up and down, which easily leads to uneven mixing of materials. At the same time, the equipment cannot perform more thorough up and down synchronous stirring of casting sand core materials, which cannot meet the needs of daily use.

[0006] To achieve the above objectives, the present invention provides the following technical solution: a casting sand core raw material mixing mechanism, comprising a mixing barrel, wherein flow guide side covers are fixedly connected to the four corners of the side of the mixing barrel, an adjustment component is provided on the front of the mixing barrel, and stirring components are provided at the upper and lower ends of the mixing barrel;

[0007] The adjustment assembly includes a lifting side cover, which is fixedly connected to the front of the mixing tank, and a lifting push plate is movably connected inside the lifting side cover.

[0008] The mixing assembly includes a top seat and a base. The top seat is fixedly connected to the top of the mixing tank, and the base is fixedly connected to the bottom of the mixing tank. The top seat and the base have the same structure but are oriented in opposite directions.

[0009] Preferably, a drive motor is provided at one end of the top seat and the base that are far apart from each other, one end of the drive motor is fixedly connected to an extension sensor, and one end of the extension sensor is fixedly connected to a stirring blade.

[0010] Preferably, a material control valve seat is fixedly connected to the back of the top seat and the base.

[0011] Preferably, an adjusting motor is provided at the bottom of the lifting side cover, and a reciprocating lead screw is provided inside the lifting side cover.

[0012] Preferably, a sealing sleeve is fitted on the outer surface of the lifting push plate, and limit sliders are fixedly connected to both sides of the sealing sleeve. Positioning plates are fixedly connected to the upper and lower ends of the inner wall of the lifting side cover.

[0013] Preferably, the mixing tank is fixedly connected to two limit side covers on both sides, the bottom of the mixing tank is fixedly connected to a support base, and the inner wall of the flow guide side cover is provided with a flow guide mesh groove.

[0014] Compared with the prior art, the beneficial effects of this utility model are:

[0015] This casting sand core material mixing mechanism, through its mixing tank, guide side cover, lifting side cover, lifting push plate, adjusting motor, reciprocating screw, sealing sleeve, limit slider, positioning plate, limit side cover, support base, and guide mesh channel, enables the equipment to perform more efficient up-and-down flow mixing of casting sand core materials. In actual use, the operator first fills the mixing tank with the casting sand core material to be mixed, and then starts the adjusting motor at the top of the lifting side cover, which drives the lifting push plate up and down in the center of the mixing tank via the internal reciprocating screw. During the lifting and adjusting operation, the lifting push plate can be limited to rise and fall along the limiting side covers on both sides of the mixing tank through the sealing sleeve and limiting slider on the outer surface. The positioning plates at the upper and lower ends of the inner wall of the lifting side cover can also position the lifting push plate at the upper and lower ends of the inner wall of the mixing tank. At the same time, in conjunction with the guide mesh grooves on the inner wall of the four-sided guide side cover of the mixing tank, the casting sand core raw material can be fully squeezed up and down inside the mixing tank, and the up and down circulation mixing operation can be completed, which improves the mixing effect of the equipment on the casting sand core raw material and reflects the practicality of the equipment design.

[0016] This casting sand core material mixing mechanism, through its mixing tank, top seat, base, drive motor, extension sensor, stirring blades, and material control valve seat, further enhances the overall efficiency of the equipment. During daily use, operators can install the top seat and base at the upper and lower ends of the mixing tank, respectively. The mixing tank is then supported and fixed by a support base. The material control valve seat on the back of the top seat and base allows for rapid feeding and discharging of the casting sand core material inside the mixing tank. Simultaneously, the drive motors at opposite ends of the top seat and base can be activated to drive two sets of extension sensors and stirring blades, causing them to move up and down within the mixing tank. This ensures that the casting sand core material receives thorough contact and mixing while the lifting pusher moves up and down within the mixing tank, demonstrating the comprehensive design of the equipment.

Limiting side covers 16 are fixedly connected to both sides of the mixing tank 1. A support base 17 is fixedly connected to the bottom of the mixing tank 1. A flow guide mesh groove 18 is provided on the inner wall of the flow guide side cover 2.

[0025] The mixing assembly includes a top seat 5 and a base 6. The top seat 5 is fixedly connected to the top of the mixing tank 1, and the base 6 is fixedly connected to the bottom of the mixing tank 1. The top seat 5 and the base 6 have the same structure but opposite directions. A drive motor 7 is provided at the ends of the top seat 5 and the base 6 that are far apart from each other.

A material control valve seat 10 is fixedly connected to the back of the top seat 5 and the base 6.

[0026] Working Principle: During use, the operator first fills the mixing drum 1 with the casting sand core material to be mixed. Then, the adjusting motor 11 at the top of the lifting side cover 3 is activated, causing it to drive the lifting push plate 4 to move up and down within the center of the mixing drum 1 via the internal reciprocating screw 12. At this time, the lifting push plate 4 can be limited up and down along the limiting side covers 16 on both sides of the mixing drum 1 by the sealing sleeve 13 and the limiting slider 14 on its outer surface. The positioning plates 15 at the upper and lower ends of the inner wall of the lifting side cover 3 also allow for the lifting and positioning of the lifting push plate 4 at the upper and lower ends of the inner wall of the mixing drum 1. Simultaneously, in conjunction with the guide mesh grooves 18 on the inner wall of the four-sided guide side covers 2 of the mixing drum 1, the casting sand core material can be fully squeezed up and down inside the mixing drum 1, achieving complete mixing. The mixing operation achieves a vertical circulating flow, improving the mixing effect of the casting sand core material. During daily use, the operator can install the top seat 5 and the base 6 at the upper and lower ends of the mixing tank 1, respectively. The mixing tank 1 is then supported and fixed by the support seat 17. The material control valve seat 10 on the back of the top seat 5 and the base 6 can be used to quickly feed and discharge the casting sand core material inside the mixing tank 1. At the same time, the drive motor 7 at the opposite end of the top seat 5 and the base 6 can be started simultaneously to drive the two sets of extension sensors 8 and stirring blades 9 to start stirring inside the mixing tank 1. This ensures that the casting sand core material is fully contacted and mixed while the lifting pusher 4 moves up and down inside the mixing tank 1 to flow the material. The above is the complete working principle of this utility model.
