AI Technical Summary
During the disappearing mold casting process, the casting product is prone to stick to sand after being taken out of the sand mold, which leads to difficulty in removing sand, and existing sand removal devices are prone to damage to the castings.
The combination of vibration and wind blowing is used to drive the castings to vibrate through the vibration table, and multiple fans are arranged around the sand removal box to generate wind blows to the castings, causing the adhered sand to fall off, and the fallen sand is collected through the funnel and the sand storage assembly.
The rapid and safe removal of sand from the casting is achieved, avoiding the waste of sand and protecting the outer surface of the casting.

Abstract
Description
Technical Field
[0001] The present application relates to the technical field of lost foam casting, and in particular to a sand removal device for lost foam casting. Background Art
[0002] In the lost foam casting process, firstly, a foam model with the same size and shape as the casting is made. These models can exist alone, or multiple models can be bonded together to form a group of models. The model needs to be coated with refractory material to separate the molten metal from the sand to prevent sand from sticking. Then it is buried in the casting sand, and then the molten metal is poured in. Under the high temperature molten metal, the foam model will be heated and vaporized and disappear, and the molten metal will replace the space occupied by the original foam mold. After solidification, the desired metal casting is obtained.
[0003] After the casting product is taken out of the sand mold, sand will stick to it, so a fast sand removal device that will not scratch the casting is needed. Summary of the invention
[0004] The purpose of the present application is to provide a sand removal device for lost foam casting in order to solve the above-mentioned problem, which adopts a combination of vibration and wind blowing to make the sand adhered to the casting fall off, and is provided with measures for collecting the fallen sand to avoid waste of sand.
[0005] This application achieves the above objectives through the following technical solutions:
[0006] A sand removal device for lost foam casting comprises a sand removal box, a bracket, a vibration table and a fan. The sand removal box is a hollow box with an open top. The bracket is fixedly connected to the inside of the sand removal box, the vibration table is fixedly arranged on the top surface of the bracket, an opening is opened on the bracket for leaking sand, a plurality of fans are fixedly arranged on the side of the sand removal box, and legs are arranged at the four corners of the bottom of the sand removal box.
[0007] Preferably, the bottom of the sand removal box is connected to a funnel, and the bottom outlet of the funnel is connected to a sand storage assembly.
[0008] Preferably, the sand storage assembly comprises a drawer shell and a drawer box, the top of the drawer shell is communicated with the bottom outlet of the funnel, and the drawer box is arranged on the drawer shell.
[0009] Preferably, a box cover is hingedly provided at the top opening of the sand removal box.
[0010] Preferably, there are four fans, which are arranged one by one on four sides of the sand removal box. The fans are arranged obliquely, and the air outlets face the vibration table.
[0011] Compared with the prior art, the present application adopts a vibration table and arranges multiple fans around the sand removal box. While driving the casting to vibrate, the wind generated by the fans blows toward the casting, causing the sand adhering to the casting to fall off, thereby not damaging the outer surface of the casting. Measures are also provided for collecting the fallen sand to avoid waste of sand. BRIEF DESCRIPTION OF THE DRAWINGS

[0018] The technical solutions in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, rather than all of the embodiments.
[0019] In the description of this application, it should be understood that the terms "upper", "lower", "front", "back", "left", "right", "top", "bottom", "inside", "outside" and the like indicate directions or positional relationships based on the attached Figure 1 , and is only for the convenience of describing the present application and simplifying the description, and does not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as limiting the present application.
[0020] like Figure 1-3 As shown, a sand removing device for lost foam casting comprises a sand removing box 1, a bracket 4, a vibrating table 6 and a fan 7. The sand removing box 1 is a hollow box with an open top. The bracket 4 is fixedly connected to the inside of the sand removing box 1, a vibrating table 6 is fixedly arranged on the top surface of the bracket 4, an opening 5 is opened on the bracket 4 for leaking sand, a plurality of fans 7 are fixedly arranged on the side of the sand removing box 1, and legs 8 are arranged at the four corners of the bottom of the sand removing box 1.
[0021] Specifically, the vibration table 6 is a prior art, which drives the casting to vibrate intermittently to cause sand to fall off, and multiple fans 7 can be started at the same time to generate wind to blow toward the casting.
[0022] Preferably, the bottom of the sand removal box 1 is connected to a funnel 3, and the bottom outlet of the funnel 3 is connected to a sand storage assembly.
[0023] Specifically, the bottom of the sand box 1 is open to be connected with the funnel 3, and the funnel 3 collects sand and sends it into the sand storage assembly. At the same time, the bottom outlet of the funnel 3 is a small opening to prevent sand from flowing back.
[0024] Preferably, the sand storage assembly comprises a drawer shell 9 and a drawer box 10 , the top of the drawer shell 9 is communicated with the bottom outlet of the funnel 3 , and the drawer box 10 is arranged on the drawer shell 9 .
[0025] Specifically, the sand falls on the funnel 3 and is then discharged from the bottom outlet of the funnel 3 into the drawer box 10 .
[0026] Preferably, a box cover 2 is hingedly provided at the top opening of the sand removal box 1.
[0027] Specifically, when the sand removal work starts, the box cover 2 is closed to prevent the wind generated by the fan 7 from leaking.
[0028] Preferably, there are four fans 7 , which are arranged one by one on four sides of the desander box 1 . The fans 7 are arranged obliquely, and the air outlets face the vibration table 6 .
[0029] Specifically, the fan 7 is tilted toward the casting on the vibration table 6 so that wind blows toward the casting, and the wind force blows away the sand on the casting.
[0030] In the above structure, the product to be cleaned of sand is placed on the vibration table 6, and then the vibration table 6 is started intermittently, and all the fans 7 are started synchronously to blow toward the product placed on the vibration table 6. The sand adhering to the vibration table 6 is cleaned by driving the product to vibrate and the wind blowing toward the product from all sides. The sand passes through the opening 5 and falls on the funnel 3, and then is discharged from the bottom outlet of the funnel 3 into the drawer box 10, so as to collect the sand adhering to the product for recycling. The drawer box 10 can be taken out of the drawer shell 9 by pulling out the drawer box 10, so as to clean the sand in the drawer box 10.
