Description

Technical Field

[0001] The present application belongs to the technical field of precision casting molds, and more specifically, relates to a precision casting mold coating cleaning device. Background Art

[0002] With the rapid development of modern industrial technology, the importance of precision casting technology in the production process has become increasingly prominent. It is widely used in the production of blank parts in various fields such as automobiles, aerospace, and industrial machinery, and has a vital impact on product quality and production efficiency.

[0003] The precision casting process usually involves coating the outer surface of a wax mold with quartz sand, curing it, and then heating and melting the wax mold to form a mold shell, i.e., a precision casting mold. During the mold shell production process, the wax mold needs to be dipped in paint (slurry) and adhered with quartz sand multiple times. The above process will cause a large amount of quartz sand particles or paint particles after bonding and curing to be deposited in the paint in the barrel. If they are not removed in time, the quality of the paint will be greatly reduced, which is not conducive to the uniform coating of the paint. Currently, there are some mechanical devices for slurry removal on the market, but most of them have complex structures, are not convenient to operate, and have high production and maintenance costs. Therefore, it is necessary to solve the above technical problems. Summary of the invention

Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of the features. In the description of this application, the meaning of "plurality" is two or more, unless otherwise clearly and specifically defined.

[0030] Please also read Figures 1 to 3Now, a precision casting mold paint cleaning device provided in an embodiment of the present application is described. The precision casting mold paint cleaning device comprises a bracket 101, a material barrel 102, an agitator 103, a mesh sheet 104 and a material discharge assembly. The material barrel 102 is installed on the bracket 101 and has an open top; the agitator 103 is arranged inside the material barrel 102 and is used for rotation; the front end of the mesh 104 along the rotation direction of the agitator 103 is spaced from the side wall of the material barrel 102 and forms an inlet 105, and the end along the rotation direction of the agitator 103 is connected to the side wall of the material barrel 102, the mesh 104 and the side wall of the material barrel 102 form a sedimentation area 106 and the mesh 104 has a number of evenly distributed mesh openings, and the bottom wall of the material barrel 102 located in the sedimentation area 106 is provided with a through blanking hole; the blanking assembly includes a relay pipe 107 and an upper valve 108 and a lower valve 109 installed on the relay pipe 107 and distributed along the axial direction of the relay pipe 107, and the relay pipe 107 is located outside the material barrel 102 and connected to the blanking hole.

[0031] According to the above structure provided in the present embodiment, since the impurity particles in the slurry are heavier than the normal slurry, when the agitator 103 rotates to stir the slurry in the barrel 102, the centrifugal force generated by the impurity particles mixed in the slurry will cause the impurity particles to be thrown to the side wall of the barrel 102, so that the impurity particles will naturally enter the sedimentation area 106 from the inlet 105 under the action of the centrifugal force of the rotation of the slurry. Due to the blocking effect of the mesh 104, the flow speed of the slurry including the impurity particles in the sedimentation area 106 slows down, and the impurity particles will settle and collect in the sedimentation area, and enter the relay pipe 107 through the drop hole set in the sedimentation area 106. The remaining slurry without impurities will pass through the mesh port set on the mesh 104 and continue to rotate in the barrel 102. In this way, the impurities in the slurry can be continuously, efficiently and quickly removed during the process of dipping the wax mold into the slurry, and the cost is low, which is far superior to the prior art. It should be noted that in this embodiment, the upper valve 108 can be set to a normally open state or a closed state. When the upper valve 108 is closed and the lower valve 109 is opened, the impurities that fall into the relay pipe 107 can be discharged from the relay pipe 107, while preventing the slurry in the barrel 102 from being discharged along with the impurities.

[0032] In another embodiment of the present application, please refer to Figures 1 to 3The barrel 102 has two straight side walls 110 arranged at an angle, and a large arc side wall 111 and a small arc side wall 112 connected to the two straight side walls 110, and the agitator 103 is installed at the center of the large arc side wall 111. According to the above structure provided in this embodiment, the straight side wall 110 and the small arc side wall 112 can form a larger sedimentation area 106, which is beneficial to improve the slag removal efficiency of the slurry. The best embodiment is that the straight side wall 110 and the large arc side wall 111 are tangent structures, so that particulate impurities can enter the sedimentation area 106 more easily. In addition, since the agitator 103 is installed at the center of the large arc side wall 111, it can effectively avoid interference with the mesh 104. At the same time, when the agitator 103 rotates to stir the slurry, the flow resistance of the slurry is smaller, which is beneficial to drive the agitator 103 to rotate with less power, which has the effect of energy saving.

[0033] In another embodiment of the present application, please refer to Figures 1 to 3 , the mesh 104 is in an arc shape opposite to the large arc side wall 111. According to the above structure provided in this embodiment, the mesh 104 can be more adapted to the shape of the barrel 102, which can make the impurities in the slurry enter the sedimentation area 106 more conveniently on the one hand, and can better avoid interference with the agitator 103 on the other hand, and is also conducive to making the flow resistance of the slurry smaller when the agitator 103 rotates to stir the slurry, which is conducive to driving the agitator 103 to rotate with less power, thereby achieving energy-saving effect.

[0034] In another embodiment of the present application, please refer to Figures 1 to 3 , the radius of the mesh 104 is the same as the radius of the large arc side wall 111. According to the above effects provided in this embodiment, the mesh 104 can not only effectively avoid interference with the large arc side wall 111, but also help to maximize the use of the space of the barrel 102 and more efficiently use the agitator 103, thereby improving the slurry deslagging efficiency.

[0035] In another embodiment of the present application, please refer to Figures 1 to 3 The precision casting mold paint cleaning device also includes a front support column 113 and a rear support column 114 disposed at both ends of the mesh 104. The front support column 113 and the rear support column 114 are provided with a card slot 115 extending along the height direction of the barrel 102, and the mesh 104 is detachably connected to the card slot 115. According to the above structure provided in this embodiment, when the mesh 104 is blocked, the mesh 104 can be conveniently taken out of the card slot 115 and replaced, which is conducive to the long-term and stable operation and use of the precision casting mold paint cleaning device provided in this embodiment.

[0036] In another embodiment of the present application, please refer to Figures 1 to 3A guide vane 116 is connected to the front support column 113, and the guide vane 116 gradually moves away from the side wall of the barrel 102 in a direction away from the inlet 105. According to the above structure provided in this embodiment, the guide vane 116 can further facilitate the impurities in the slurry to enter the sedimentation area 106 from the inlet 105, thereby improving the slurry deslagging efficiency and reducing the deslagging cost.

[0037] In another embodiment of the present application, please refer to Figures 1 to 3 The material discharge assembly further includes a conical tube 117, the large end of the conical tube 117 is connected to the material discharge hole, and the small end of the conical tube 117 is connected to the relay tube 107. According to the above structure provided in this embodiment, the conical tube 117 can be more conducive to the impurities in the settling area 106 entering the relay tube 107 and facilitating the removal of the impurities, which is conducive to further improving the slurry deslagging efficiency.
