Description

Technical Field

[0001] The utility model relates to the technical field of casting moulds, in particular to a casting mould which is convenient for cleaning. Background Art

[0002] Sand casting is a common metal casting method that uses sand molds to create castings;

[0003] In the existing sand mold casting technology, when removing the mold, the casting needs to be clamped out of the sand mold with a clamp, and then the casting needs to be gently tapped with a small hammer to make the sand and soil on the surface of the casting fall off to clean the surface of the casting;

[0004] The existing method of cleaning the surface sand of castings is labor-intensive and only applicable to medium-sized castings, such as motor covers and other shell structures. For small castings, this cleaning method is more complicated and requires cleaning of multiple castings, which is less efficient. Utility Model Content

[0005] The technical problem to be solved by the utility model is that the existing casting cleaning is relatively labor-intensive and inconvenient to clean small castings.

[0006] The technical solution adopted by the utility model is a method for facilitating the cleaning of casting casting molds, including a base, characterized in that: a limiting frame is fixed on the upper side of the base, a casting mold box is placed in the limiting frame above the base, a circular limiting plate is clamped above the limiting frame, a plurality of compression springs are fixed to four inner sides of the limiting frame, an extension plate is fixed to one side of the base, a motor seat is fixed to the upper side of the extension plate, an electromagnetic motor is fixed to the upper side of the motor seat, an output end of the electromagnetic motor is connected to a transmission shaft through a coupling, a cam is fixed to one end of the transmission shaft, a slot is opened on one side of the limiting frame at the cam, and the side surface of the cam passes through the slot and contacts one side of the casting mold box.

[0007] As a further solution of the utility model: one end of the compression spring contacts the outer side of the casting mold box, so that the casting mold box can shake in the limiting frame.

[0008] As a further solution of the utility model: a limiting ring is fixed on one side of the limit frame at the transmission shaft, and a shaft support rod is fixed on the upper side of the extension plate at the transmission shaft to limit the position of the transmission shaft and keep it rotating stably.

[0009] As a further solution of the utility model: the inner width and length of the circular limiting plate are greater than the outer width and length of the casting mold box, so as to facilitate limiting the position of the casting mold box.

[0010] As a further solution of the utility model: the maximum radius of the cam is less than half of the maximum length of the slot hole, so that the cam can rotate smoothly.

[0011] As a further solution of the utility model: the electromagnetic motor is electrically connected to an external power supply.

[0012] Compared with the prior art, the utility model has the following advantages: the utility model adds a cam structure and a compression spring assembly, and the cam periodically strikes the casting mold box. When the casting mold box is displaced, the rebound force of the compression spring assembly causes the casting mold box to continuously vibrate in the limit frame until the sand in the casting mold box is loosened, thereby facilitating demoulding of the casting.

[0018] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0019] The utility model provides a technical solution to solve the existing problems raised in the background technology.

[0020] Combined with Figure 1-2It can be known that the steel pipe has a multi-layer composite structure, including a base 1, characterized in that: a limiting frame 2 is fixed on the upper side of the base 1, a casting mold box 3 is placed in the limiting frame 2 above the base 1, a circular limiting plate 4 is clamped on the limiting frame 2, and a number of compression springs 5 ​​are fixed on the four inner sides of the limiting frame 2, an extension plate 6 is fixed on one side of the base 1, a motor seat 7 is fixed on the upper side of the extension plate 6, an electromagnetic motor 8 is fixed on the upper side of the motor seat 7, the output end of the electromagnetic motor 8 is connected to a transmission shaft 9 through a coupling, and a cam 10 is fixed at one end of the transmission shaft 9 for hitting the outside of the casting mold box 3, a slot 1.1 is opened on one side of the limiting frame 2 at the cam 10, and the side of the cam 10 passes through the slot 1.1 and contacts one side of the casting mold box 3.

[0021] One end of the compression spring 5 is in contact with the outer side of the casting mold box 3 to facilitate the casting mold box 3 to shake in the limit frame 2; a limiting ring 1.2 is fixed to the transmission shaft 9 on one side of the limit frame 2, and an axis support rod 11 is fixed to the transmission shaft 9 on the upper side of the extension plate 6 to facilitate limiting the position of the transmission shaft 9 and keep it rotating stably; the inner width and length of the circular limiting plate 4 are greater than the width and length of the outer side of the casting mold box 3, so as to facilitate limiting the position of the casting mold box 3; the maximum radius of the cam 10 is less than half of the maximum length of the slot 1.1, so that the cam 10 can rotate smoothly.

[0022] The working principle of the present application is as follows: when cleaning the casting, first pour a portion of lubricating oil into the limit frame 2 for lubrication, then place the casting mold box 3 in the limit frame 2, then clamp the circular limit plate 4 on the top of the limit frame 2, and then start the electromagnetic motor 8 to drive the transmission shaft 9 to rotate, and the transmission shaft 9 will drive the cam 10 to rotate. When the cam 10 rotates, it will hit the outside of the casting mold box 3. After the casting mold box 3 is thrust, it will slide on the base 1. When moving, the casting mold box 3 will also contact the compression spring 5, and then the compression spring 5 will move in the opposite direction under the compression. Under the continuous hitting of the cam 10 and the rebound of the compression spring 5, the sand in the casting mold box 3 will gradually loosen, and then the casting can be directly taken out of the casting mold box 3 for subsequent processing.

[0023] The above description of the utility model and its implementation methods is not restrictive. The drawings show only one implementation method of the utility model, and the actual structure is not limited thereto. In short, if ordinary technicians in this field are inspired by it and design structural methods and embodiments similar to the technical solution without creativity without departing from the purpose of the invention of the utility model, they should all fall within the protection scope of the utility model.
