AI Technical Summary
In the production of large castings in small batches, the uncertainty of the casting size during pit molding leads to the need for a large amount of back sand filling, which increases the amount of manual labor and production costs.
It adopts a filling block structure consisting of cement blocks, steel plates, and handles. The cement blocks have round steel bars and circular baffles inside, and the steel plates are fixed on the outside. There are recesses under the round steel bars to replace the backing sand. By operating the handle, the chain is hung in the recess to hang heavy objects, which prevents the cement blocks from breaking and improves their service life.
By using filler blocks instead of backing sand, molding materials are saved, production costs are reduced, work efficiency is improved, damage to cement blocks is avoided, and service life is extended.

Abstract
Description
TECHNICAL FIELD
[0001] The utility model relates to a filling block structure, especially a filling block for pit molding in foundry production. BACKGROUND
[0002] It is known that, in small batch production of single large castings, the molding process is generally produced in the mode of pit molding, and the shape and size of the workshop pit are determined. Because different customer order drawings result in different shapes and sizes of castings, the size of the castings is uncertain. When producing castings with small profile sizes, a large amount of back sand needs to be filled outside the pit mold in the pit to complete the molding work, which results in a large amount of manual work and increases the production cost. Therefore, a filling block structure that reduces the amount of work and can be used for molding has become the basic demand of those skilled in the art. SUMMARY
[0003] In order to overcome the deficiencies in the background art, the utility model discloses a filling block for pit molding in foundry production.
[0004] In order to achieve the object of the application, the utility model adopts the following technical scheme:
[0005] A filling block for pit molding in foundry production, comprising a filling block body, the filling block body is composed of a cement block, a steel plate and a handle, the cement block is of a rectangular structure, round steels are arranged on the left and right sides inside the cement block, circular baffles are extended outside the two ends of the round steels, the diameter of the circular baffles is greater than that of the round steels, the outer ends of the round steels and the circular baffles form the handle, steel plates are fixed on the upper and lower front and rear surfaces of the cement block, and the handles are located outside the steel plates.
[0006] The filling block for pit molding in foundry production is provided with a recess below the round steel outside the steel plate, and the recess is an arc-shaped recess or a square recess.
[0007] Due to the adoption of the above technical scheme, the utility model has the following beneficial effects:
[0008] The filling block for pit molding in foundry production disclosed by the utility model places the filling block instead of back sand at the back sand position of the pit, thereby saving molding materials; four steel plates are fixed outside the cement block, which avoids the phenomenon of powdering due to heating and the phenomenon of the cement block being broken by the shovel of the excavator when the sand is removed from the box, and the service life is relatively long; the utility model has the advantages of simple structure, convenient use, improved work efficiency and saved production cost. BRIEF DESCRIPTION OF DRAWINGS
[0009] Figure 1 It is a structure schematic view of the utility model.
[0010] In the figure: 1, steel plate; 2, cement block; 3, handle; 4, recess; 5, baffle. DETAILED DESCRIPTION
[0011] The utility model can be explained in detail by the following examples, the purpose of the utility model is to protect all technical improvements within the scope of the utility model.
[0012] The accompanying drawings Figure 1 The filling block for pit molding in foundry production, including filling block body, filling block body is by cement block 2, steel plate 1 and handle 3 is composed, cement block 2 is rectangular structure, and the round steel is arranged in the left and right sides in its inside, and the both ends of the round steel are extended with the circular baffle 5 outside, and the diameter of the circular baffle 5 is greater than the diameter of the round steel, and the outer end of the round steel and the circular baffle 5 form the handle 3, and the steel plate 1 is fixed on the upper and lower front and back of the cement block 2, the handle 3 is located outside the steel plate 1, and the recess 4 is arranged below the round steel outside the steel plate 1, and the recess 4 is arc concave or square concave.
[0013] The filling block for pit molding in foundry production is implemented, when small size castings are cast in the existing ground pit, the filling block body is placed at the back sand of the casting, and one or more can be placed according to the space, the process of manual sand filling is saved, the chain is hung at the recess 4 of the handle 3 by using the crown block, the skidding phenomenon during lifting is avoided, and the round steel of the handle 3 is integrally arranged with the steel plate 1 and the cement block 2, so that the fracture phenomenon in the use engineering is avoided; the filling block body is used instead of filling a large amount of sand and water glass, so that the cost is reduced, and the work efficiency is improved.
[0014] The part not described in the utility model is prior art.
[0015] In order to disclose the invention purpose of the utility model, the examples selected in the text are considered to be appropriate at present, but it should be understood that the utility model aims to include all changes and improvements of all embodiments within the scope of the concept and utility model.
