Technical Field
[0001] This application relates to the technical field of casting equipment, and particularly relates to a core shooter. Background Art
[0002] A shot blasting and pressing molding machine uses compressed air to inject a core sand mixture with a liquid or solid thermosetting resin as a binder into a heated core box. The core sand quickly preheats and hardens to a certain thickness in the core box, and after being taken out, a high-quality core sand product with a smooth surface and precise dimensions is formed.
[0003] During the traditional core sand production process, the pipeline is prone to blockage during the raw material sieving process, resulting in low core sand production efficiency. Utility Model Content
[0004] In order to reduce the probability of pipeline blockage during core sand production and improve core sand production efficiency, this application provides a core shooter.
[0005] A core shooter provided by this application adopts the following technical solution: It includes a sieving structure and a temporary storage box. The temporary storage box is arranged below the sieving structure. The sieving structure and the temporary storage box are connected and communicated through a sand delivery pipe. A flow regulation component is arranged on the sand delivery pipe. The flow regulation component is used to change the flow rate of the raw material from the sieving structure to the temporary storage box. The temporary storage box is connected with a discharge pipe.
[0006] By adopting the above technical solution, the flow regulation component can adjust the flow rate of the raw material from the sieving structure to the temporary storage box according to the actual working conditions, reduce the probability of pipeline blockage during core sand production, and improve core sand production efficiency.
[0007] Preferably, the sieving structure includes a sieving box and a sieving mesh arranged in the sieving box. The sieving box is provided with an open top. The sieving mesh is used to cover the open top of the sieving box. The sieving mesh is detachably connected to the sieving box.
[0008] By adopting the above technical solution, the sieving mesh can sieve out impurities in the raw material entering the temporary storage box, improving the quality of the formed core sand.
[0009] Preferably, an air pump is arranged on one side wall of the temporary storage box. The air pump is connected and communicated with the side wall of the temporary storage box far away from the discharge pipe.
[0010] By adopting the above technical solution, the air pump works to accelerate the discharge speed of the raw material in the temporary storage box from the discharge pipe.
[0011] Preferably, the temporary storage box includes a box body with an open top and a box cover for sealing the open top of the box body. The box cover and the box body are detachably connected. A sealing ring is provided on the box cover, and the side of the sealing ring away from the box cover is closely attached to the top of the box body.
[0012] The detachable connection between the box body and the box cover results in poor sealing of the box cover to the box body. During the operation of the air pump, gas will leak from the gap between the box cover and the box body. By adopting the above technical solution, the sealing ring improves the sealing effect of the box cover to the box body, and further speeds up the discharging speed of the raw materials in the temporary storage box from the discharging pipe.
[0013] Preferably, the flow regulating assembly includes a flow regulating door, which is arranged in the sand conveying pipe. The flow regulating door is used to seal the sand conveying pipe, and the flow regulating door is rotationally connected to the inner wall of the sand conveying pipe in a damped manner with the radial direction of the sand conveying pipe as the axis.
[0014] By adopting the above technical solution, during the damped rotation of the flow regulating door, the opening and closing angle between the flow regulating door and the sand conveying pipe changes, thereby changing the flow rate of the raw materials from the sieving structure to the temporary storage box.
[0015] Preferably, a vibration assembly is arranged on one side wall of the sieving box. The vibration assembly includes a vibration box, a vibration motor and an eccentric vibration wheel. The vibration box is arranged on one side wall of the sieving box. The vibration motor is fixedly arranged at the central position inside the vibration box. The eccentric vibration wheel is eccentrically connected to the output shaft of the vibration motor. The vibration motor drives the eccentric vibration wheel to swing reciprocally, and the peripheral wall of the eccentric vibration wheel is used to strike the inner wall of the vibration box.
[0016] By adopting the above technical solution, when the vibration motor works, it drives the eccentric vibration wheel to swing reciprocally. During the reciprocating swing of the eccentric vibration wheel, the eccentric vibration wheel orderly strikes the inner wall of the vibration box, thereby giving the sieving box vibration, accelerating the sieving speed and improving the efficiency.
[0017] Preferably, a dovetail block is arranged on the output shaft of the vibration motor. A dovetail groove for the dovetail block to slide and be embedded is formed on the end face of the eccentric vibration wheel close to the vibration motor. The depth direction of the dovetail groove is arranged along the axial direction of the eccentric vibration wheel, and the length direction of the dovetail groove is arranged along the radial direction of the eccentric vibration wheel. The dovetail block and the eccentric vibration wheel are connected in a reciprocating sliding manner that can be positioned.
[0018] By adopting the above technical solution, the dovetail block is embedded in the dovetail groove, reducing the probability of the connection relationship between the eccentric vibration wheel and the vibration motor being disengaged; and the eccentric vibration wheel can slide in a positioned manner, so that the eccentricity of the eccentric vibration wheel can be adjusted, thereby making the vibration effect adjustable.

Detailed implementation manners
[0031] The present application will be further described in detail below with reference to the accompanying drawings.
[0032] In order to reduce the probability of pipeline blockage during the production of sand cores and improve the production efficiency of sand cores, the present application provides a sand core machine.
[0033] Refer to Figure 1 、 Figure 2 , a sand core machine, including a screening structure 11 and a temporary storage box 12. The temporary storage box 12 is arranged below the screening structure 11. The screening structure 11 and the temporary storage box 12 are connected and communicated through a sand conveying pipe 113. In this embodiment, the screening structure 11 includes a screening box 111 and a screening mesh 112 arranged in the screening box 111. The temporary storage box 12 is arranged directly below the screening box 111. The sand conveying pipe 113 is arranged vertically and is connected and communicated with the screening box 111 and the temporary storage box 12 at both ends respectively.
[0034] The screening box 111 is provided with an open top. The screening mesh 112 is used to cover the open top of the screening box 111, and the screening mesh 112 is detachably connected to the screening box 111; the temporary storage box 12 includes a box body 121 with an open top and a box cover 122 for sealing the open top of the box body 121. The box cover 122 and the box body 121 are detachably connected, and the box cover 122 and the box body 121 are detachably connected through a plurality of fixing bolts 123. The plurality of fixing bolts 123 are arranged at intervals along the circumferential direction of the temporary storage box 12, and the fixing bolts 123 sequentially pass through the box cover 122 and the top of the box body 121; specifically, the screening mesh 112 is arranged horizontally, and connecting parts 114 are vertically arranged on four sides of the screening mesh 112 perpendicular to the screening mesh 112. One side wall of the connecting part 114 is closely attached to the box wall of the screening box 111. Two connecting bolts 115 are arranged on each connecting part 114. The two connecting bolts 115 are symmetrically arranged along the length direction of the connecting part 114 and pass through the connecting part 114, and the connecting bolts 115 are threadedly connected to the inner wall of the screening box 111 after passing through the connecting part 114.
[0035] Furthermore, an air pump 124 is provided on one side wall of the temporary storage box 12. The air pump 124 is connected to the side wall of the temporary storage box 12 away from the discharge pipe 126. When the air pump 124 works, it accelerates the discharging speed of the raw materials in the temporary storage box 12 from the discharge pipe 126. Since the box cover 122 and the box body 121 are detachably connected, the sealing performance of the box cover 122 on the box body 121 is not good. During the operation of the air pump 124, the gas will leak out from the gap between the box cover 122 and the box body 121. Therefore, a sealing ring 125 is provided on the box cover 122. The side of the sealing ring 125 away from the box cover 122 closely adheres to the top of the box body 121. The sealing ring 125 improves the sealing effect of the box cover 122 on the box body 121 and accelerates the discharging speed of the raw materials in the temporary storage box 12 from the discharge pipe 126.
[0036] Reference Figure 1 、 Figure 3 、 Figure 4 During the sieving process of the raw materials, the pipeline is prone to blockage, resulting in a low production efficiency of the sand core. A flow regulation component is provided on the sand conveying pipe 113. The flow regulation component is used to change the flow rate of the raw materials from the sieving structure 11 to the temporary storage box 12. A discharge pipe 126 is connected to the temporary storage box 12, and a flow regulation component is also provided on the discharge pipe 126. Specifically, the flow regulation component includes a flow regulation door 13. The flow regulation door 13 is arranged in the sand conveying pipe 113 and the discharge pipe 126. The flow regulation door 13 is used to seal the sand conveying pipe 113 and the discharge pipe 126. The flow regulation door 13 is rotatably connected to the inner walls of the sand conveying pipe 113 and the discharge pipe 126 with the radial direction of the sand conveying pipe 113 and the discharge pipe 126 as the axis. During the damping rotation of the flow regulation door 13, the opening and closing angle between the flow regulation door 13 and the sand conveying pipe 113 changes, thereby changing the flow rate of the raw materials from the sieving structure 11 to the temporary storage box 12 and the flow rate of the raw materials discharged from the temporary storage box 12, reducing the probability of pipeline blockage during the production process of the sand core, and improving the production efficiency of the sand core.
[0037] Reference Figure 1 、 Figure 5 、 Figure 6, In order to accelerate the sieving speed, a vibration assembly 14 is provided on one side wall of the sieving box 111. The vibration assembly 14 includes a vibration box 141, a vibration motor 142 and an eccentric vibration wheel 143. The vibration box 141 is arranged on one side wall of the sieving box 111. The vibration motor 142 is fixedly arranged at the central position inside the vibration box 141. The eccentric vibration wheel 143 is eccentrically connected to the output shaft of the vibration motor 142. The vibration motor 142 drives the eccentric vibration wheel 143 to swing reciprocally. The peripheral wall of the eccentric vibration wheel 143 is used to strike the inner wall of the vibration box 141. When the vibration motor 142 works, it drives the eccentric vibration wheel 143 to swing reciprocally. During the process of the eccentric vibration wheel 143 swinging reciprocally, the eccentric vibration wheel 143 orderly strikes the inner wall of the vibration box 141, thereby giving the sieving box 111 vibration, accelerating the sieving speed and improving the efficiency.
[0038] Specifically, a dovetail block 144 is arranged on the output shaft of the vibration motor 142. A dovetail groove 145 for the dovetail block 144 to slide and be embedded is opened on the end face of the eccentric vibration wheel 143 close to the vibration motor 142. The depth direction of the dovetail groove 145 is arranged along the axial direction of the eccentric vibration wheel 143, and the length direction of the dovetail groove 145 is arranged along the radial direction of the eccentric vibration wheel 143. A plurality of positioning and adjusting holes 146 are opened on the eccentric vibration wheel 143. The plurality of positioning and adjusting holes 146 penetrate through the bottom of the dovetail groove 145. A positioning bolt 147 is arranged on the eccentric vibration wheel 143. After passing through the positioning and adjusting hole 146, the positioning bolt 147 is threadedly connected to the dovetail block 144. According to the change of the working condition, when it is necessary to change the vibration effect of the vibration box 141 on the sieving box 111, only need to slide the eccentric vibration wheel 143 along the length direction of the dovetail groove 145, and then pass the positioning bolt 147 through the corresponding positioning and adjusting hole 146 and threadedly connect it to the dovetail block 144, that is, complete the eccentric adjustment of the eccentric vibration wheel 143.
[0039] The implementation principle of a core-making machine in an embodiment of the present application is as follows: During the damping rotation of the flow regulating door 13, the opening and closing angle between the flow regulating door 13 and the sand conveying pipe 113 changes, thereby changing the flow rate of the raw material from the sieving structure 11 to the temporary storage box 12 and the flow rate of the raw material discharging from the temporary storage box 12, reducing the probability of pipeline blockage during the core-making process, and improving the core-making efficiency.

Therefore, all equivalent changes made according to the structure, shape and principle of the present application should be covered within the protection scope of the present application.
