Description

Technical Field

[0001] The utility model belongs to the technical field of casting processing, in particular to a sand-turning device for casting processing. Background Art

[0002] In the prior art, in the sand casting process, the fine sand first needs to be stirred and glued to make the fine sand sticky, and then the fine sand is placed in the upper sand box and the lower sand box for sand casting. However, it is difficult to directly obtain the fine sand that meets the composite requirements during processing and production. At this time, the mixed sand body needs to be screened through a screen to obtain suitable fine sand for the mixing process. In the application process of the sand body, there is often a problem of uneven quality of the fine sand in the sand body composition. In order to ensure quality control during the sand body mixing process, pre-screening must be performed before the sand body is mixed with glue. At present, the commonly used screening method is to use a fixed screen, but this method easily causes impurities to accumulate at a fixed position of the screen, thereby reducing the screening efficiency. Utility Model Content

[0003] In order to overcome the above defects, the utility model provides a sand casting equipment for casting processing, which solves the problem that the currently commonly used screening method is to use a fixed screen, but this method easily causes impurities to accumulate at the fixed position of the screen, thereby reducing the screening efficiency.

[0004] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a sand-turning device for casting processing, comprising a base, a tank body is connected through the base, a stirring assembly is arranged in the tank body, a feed inlet is opened on the tank body, a screening device is connected to the tank body, and a fixing device is arranged outside the screening device;

[0005] The screening device includes a feed hopper, a fixed ring is connected to the feed hopper, two fixed blocks are connected to the outside of the feed hopper, a slide rod is slidably connected inside the fixed block, a return spring is provided on the outer sleeve of the slide rod, a connecting plate is connected to one side of the feed hopper, and a vibration motor is connected to the connecting plate.

[0006] As a further solution of the utility model: a screen is installed in the feeding hopper, and a limiting hole is provided in the feeding hopper.

[0007] As a further solution of the utility model: the feed hopper corresponds to the feed port in position, and the slide bar is connected to the tank body.

[0008] As a further solution of the utility model: one end of the pull-back spring is connected under the fixing block, and the other end of the pull-back spring is connected to the tank body.

[0009] As a further solution of the utility model: the fixing device includes two long rods, the long rods are connected to the screen, and one side of the long rods is connected to a fixing plate.

[0010] As a further solution of the utility model: the fixing plate is clamped outside the fixing ring, a limiting rod is slidably connected inside the fixing plate, and the limiting rod is clamped in the limiting hole.

[0011] Compared with the prior art, the beneficial effects of the utility model are:

[0012] 1. The foundry equipment for casting processing is equipped with a hopper, a fixed block, a slide bar, a pull-back spring, a connecting plate, a vibration motor and a screen. When the material needs to be filtered, the vibration motor is started, and then the material is poured into the hopper. At this time, the vibration motor drives the connecting plate to vibrate, and then the connecting plate drives the hopper to vibrate. The hopper drives the two fixed blocks to slide outside the slide bar. At this time, the hopper drives the screen to vibrate, thereby achieving faster screening when filtering materials, avoiding the problem of material accumulation at the fixed position of the screen.

[0013] 2. The sand-turning equipment for processing castings is equipped with a long rod, a fixed plate and a limit rod. When the screen needs to be replaced, the limit rod is pulled out of the limit hole, and then the fixed plate is pulled. The fixed plate drives the long rod to move, and the long rod drives the screen to move, thereby realizing the rapid removal of the screen and facilitating the replacement or cleaning of the screen.

DETAILED DESCRIPTION

[0019] The technical solution of this patent is further described in detail below in conjunction with specific implementation methods.

[0020] like Figure 1-4 As shown, the utility model provides a technical solution: a sand-turning device for processing castings, comprising a base 1, a tank body 2 is connected through the base 1, a stirring assembly 3 is arranged in the tank body 2, a feed port 4 is opened on the tank body 2, a screening device 5 is connected to the tank body 2, a fixing device 6 is clamped outside the screening device 5, the fixing device 6 comprises two long rods 61, the long rods 61 are connected to the screen 58, one side of the long rods 61 is connected to a fixing plate 62, by setting the fixing plate 62 and the fixing ring 52, the fixing plate 62 cooperates with the fixing ring 52, so that the fixing plate 62 can be clamped outside the fixing ring 52, and will not tilt after being clamped;

[0021] The fixing plate 62 is clamped outside the fixing ring 52, and a limiting rod 63 is slidably connected inside the fixing plate 62. The limiting rod 63 is clamped in the limiting hole 59. By setting the limiting rod 63 and the limiting hole 59, the limiting rod 63 cooperates with the limiting hole 59, so that the limiting rod 63 limits the limiting hole 59, and prevents the limiting hole 59 from being separated from the limiting rod 63.

[0022] The screening device 5 includes a feed hopper 51, a screen 58 is installed in the feed hopper 51, a limit hole 59 is provided in the feed hopper 51, the feed hopper 51 corresponds to the feed port 4, a slide bar 54 is connected to the tank body 2, a fixing ring 52 is connected to the feed hopper 51, two fixing blocks 53 are connected to the outside of the feed hopper 51, the fixing blocks 53 are slidably connected with the slide bar 54, and the slide bar 54 is provided with a pull-back spring 55 on the outer sleeve. By setting the pull-back spring 55, when the vibration motor 57 is not started, the pull-back spring 55 applies elastic force to the fixing block 53 to keep it stable. When the fixing block 53 moves down outside the fixing rod, the pull-back spring 55 applies elastic force to the fixing block 53, and the elastic force drives the fixing block 53 to move, so that it can be quickly reset.

[0023] One end of the return spring 55 is connected to the fixing block 53 , and the other end of the return spring 55 is connected to the tank body 2 . A connecting plate 56 is connected to one side of the hopper 51 , and a vibration motor 57 is connected to the connecting plate 56 .

[0024] The working principle of the utility model is:

[0025] When the material needs to be filtered, the vibration motor 57 is started, and the material is poured into the hopper 51. The vibration motor 57 drives the connecting plate 56 to vibrate, and then the connecting plate 56 drives the hopper 51 to vibrate. The hopper 51 drives the two fixed blocks 53 to slide outside the slide rod 54. At this time, the hopper 51 drives the screen 58 to vibrate. When the screen 58 needs to be replaced, the limit rod 63 is pulled out of the limit hole 59, and then the fixed plate 62 is pulled. The fixed plate 62 drives the long rod 61 to move, and the long rod 61 drives the screen 58 to move. At this point, the rapid screening of the material and the splitting of the screen 58 are completed.

[0026] In the description of the present invention, it should be noted that, unless otherwise clearly specified and limited, the terms "connection", "sliding connection" and "hinge" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection, or it can be an indirect connection through an intermediate medium, or it can be the internal communication of two components. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood by specific circumstances.

[0027] The above describes in detail the preferred implementation of this patent, but this patent is not limited to the above implementation. Various changes can be made within the knowledge scope of ordinary technicians in this field without departing from the purpose of this patent.
