Description

Technical Field

[0001] The utility model belongs to the technical field of casting modeling, in particular to a sand-shooting plate to prevent sand from escaping. Background Art

[0002] The existing sand shooting plate is connected to the sand box by bolts passing through 18 through holes distributed on the edge. However, there are deviations in the processing of the sand shooting plate. The shape of the sand shooting plate or the position of the bolt holes is easy to change, which makes the bolt installation difficult and the sand shooting plate is not tightly sealed. At the same time, the existing sand shooting nozzle uses two bolts to fix the baffle to reduce sand leakage. The installation process is relatively complicated and the buffering effect of the baffle at the sand shooting nozzle is poor, and the anti-sand leakage effect is not ideal. Utility Model Content

[0003] The technical problem to be solved by the utility model is to simplify the installation process of the sand shooting nozzle, improve the sealing effect of the sand shooting plate to slow down the outflow of sand, and provide a sand shooting plate to prevent sand from running away in view of the shortcomings of the prior art.

[0004] In order to solve the above technical problems, the technical solution adopted by the utility model is:

[0005] A sand shooting plate to prevent sand from escaping, comprising: a sand shooting plate, a U-shaped groove, a sand shooting hole, a sealing groove, a sealing gasket, a sand shooting nozzle, a fixing bolt and a buffer cover; the sand shooting plate is evenly provided with 18 U-shaped grooves along the outer edge, the sand shooting holes are evenly distributed on the surface of the sand shooting plate, the surface of the sand shooting plate is provided with the sealing groove, the sealing gasket is located in the sealing groove, the top of the sand shooting nozzle is downwardly provided with a threaded groove, the side of the sand shooting nozzle is provided with a facing opening, the opening is connected with the bottom surface outlet of the sand shooting nozzle through an internal cavity, the sand shooting nozzle is screwed into the sand shooting plate through the inner thread of the sand shooting hole, and the fixing bolt passes through the top opening of the buffer cover to be connected with the sand shooting nozzle.

[0006] Furthermore, the inner diameter width and height of the U-shaped groove are both 9 mm.

[0007] Furthermore, the sealing gasket is made of high temperature resistant silicone, high temperature resistant rubber or asbestos.

[0008] Furthermore, the buffer cover is made of metal or plastic.

[0009] Compared with the prior art, the beneficial effects of the utility model are as follows:

[0010] Compared with the prior art, the utility model provides a sand shooting plate to prevent sand from escaping. The sealing performance of the sand shooting plate is improved by installing a sealing gasket on the sand shooting plate. The U-shaped bolt fixing groove reduces the restricted direction during bolt installation, which facilitates the installation of the fixing bolts of the sand shooting plate. At the same time, the buffer cover and the lateral sand outlet of the sand shooting nozzle increase the path and difficulty of the overflow of the casting sand from the sand box.

[0018] In order to better understand the present invention, the content of the present invention is further clearly described below in conjunction with the embodiments, but the protection content of the present invention is not limited to the following embodiments. In the following description, a large number of specific details are given in order to provide a more thorough understanding of the present invention. However, it is obvious to those skilled in the art that the present invention can be implemented without one or more of these details.

[0019] In the description of the present invention, it is necessary to understand that the terms "upper", "lower", "inside", "outside", etc., indicating orientations or positional relationships, are based on the orientations or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying 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 a limitation on the present invention.

[0020] In the present invention, unless otherwise clearly specified and limited, the terms such as "connection" shall be understood in a broad sense, for example, it may be a fixed connection, a detachable connection, or an integral connection; it may be a direct connection, or an indirect connection through an intermediate medium, or it may be the internal connection of two elements or the interaction relationship between two elements. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0021] Example 1

[0022] See also Figure 3-6 , including a sand shooting plate 1, a U-shaped groove 101, a sand shooting hole 102, a sealing groove 2, a sealing gasket 201, a sand shooting nozzle 3, a fixing bolt 301 and a buffer cover 302; the sand shooting plate 1 is evenly provided with 18 U-shaped grooves 101 along the outer edge, the sand shooting holes 102 are evenly distributed on the surface of the sand shooting plate 1, the surface of the sand shooting plate 1 is provided with the sealing groove 2, the surface of the sand shooting plate 1 provided with the sealing groove 2 is in contact with the sand box, the sealing gasket 201 is located in the sealing groove 2, the top of the sand shooting nozzle 3 is provided with a threaded groove downward, the side is provided with a facing opening and is connected to the cavity connected to the bottom surface of the inside of the sand shooting nozzle 3, the sand shooting nozzle 3 is screwed into the sand shooting plate 1 through the inner thread of the sand shooting hole 102, the fixing bolt 301 passes through the top opening of the buffer cover 302 and is connected to the sand shooting nozzle 3, and a section of the buffer cover 302 in the sand shooting nozzle 3 is located in the sand box.

[0023] The technical solution provided in the embodiment of the present application, the sealing gasket improves the sealing performance of the sand shooting plate, the sand shooting nozzle that is screwed into the sand shooting plate by threading reduces the opening of the sand shooting plate, and reduces the processing difficulty of the sand shooting plate. The U-groove fixing bolts reduce the difficulty of bolt installation and improve work efficiency. At the same time, the allowable range of sand shooting plate processing errors is expanded, and the production difficulty of the sand shooting plate is reduced. The casting sand in the sand box can only enter the side opening of the sand shooting nozzle after it passes through the buffer cover. The sand entering the buffer cover is easy to block the side opening of the sand shooting nozzle only by relying on the pressure of the casting sand in the box itself, which has an obvious buffering effect on slowing down the outflow of sand and can also ensure the casting effect. It has good economy and practicality.
