Description

A sliding sandbox

technical field

The invention belongs to the technical field of casting, and relates to a casting sand box, in particular to a sliding sand box.

Background technique

When sand casting is used for castings, sand boxes are generally required in the casting process, especially in the process of using a production line for operation, it is often necessary to make specific sand boxes according to specific products. The main function of the sand box is to fix the sand mold, which is convenient for demoulding during the molding process, sand mold transfer, and locking the sand mold during the box closing process; ribs are also installed inside the sand box to prevent the sand mold from sinking or deforming.

In the process of design and manufacture of traditional sandboxes, the external dimensions of the sandbox and the structure of the ribs are often designed according to the size of the casting product and the casting process, that is, the special sandbox, to achieve the optimal combination of manufacturability and sand consumption; but for each All kinds of products are designed with special sand boxes. With the increase of product varieties, a large number of sand boxes will be produced. The storage, storage and use of these sand boxes will take up a lot of resources. Moreover, when wanting to use a special sand box to produce other castings (height and inner diameter do not match), either the casting will eat too much sand, wasting molding sand, curing agent and binder; or the sand box needs to be cut ( Ribs interfere with the mold or sprue riser) to accommodate the new casting, which destroys the flask and reduces its service life. Especially when the height of the sand box is not enough, a layer of sand box must be placed on it, so that the machine cannot be used to flip the mold, and the mold can only be flipped manually. If the mold is to be removed by the machine, the sand box must be remade, which is not economical and also reduces production efficiency.

Contents of the invention

The purpose of the present invention is to realize the adjustable height and inner diameter of the sand box by designing a sliding sand box, so as to adapt to the needs of various castings in a large range.

The technical scheme that the present invention adopts in order to realize the above object is:

A sliding sand box, comprising a right-angle frame, a right-angle telescopic block, a length frame, a long-side sliding wall, a width frame, a wide-side sliding wall, a horizontal slide rail, and a vertical slide rail, and the two sides of the right-angle frame are passed through horizontal slides respectively. The rail is slidingly connected with the length frame and the width frame, and the two sides of the right-angle frame are respectively processed with a number of threaded holes at the corresponding positions on the length frame and the width frame, and bolts and different threaded holes are used to fix the relative positions of the right-angle frame and the length frame and width frame ;The longitudinal section of the right-angle frame is processed with a U-shaped groove, and a right-angle telescopic block is embedded in the groove. A number of threaded holes are correspondingly processed on the right-angle frame and the right-angle telescopic fastening. Position: The length frame and the long-side sliding wall are slidingly connected by vertical slide rails, and several threaded holes are processed at the corresponding positions on the length frame and the long-side sliding wall, and the relative positions of the length frame and the long-side sliding wall are fixed by using bolts and different threaded holes The width frame and the wide-side sliding wall are slidingly connected by vertical slide rails, and a number of threaded holes are processed at corresponding positions on the width frame and the wide-side sliding wall, and bolts and different threaded holes are used to coordinate and fix the relative positions of the width frame and the wide-side sliding wall.

Rib fixing frames are also arranged on the long-side sliding wall and the wide-side sliding wall, and the fixing ribs are installed as required.

The beneficial effects of the present invention are: the height and the inner diameter of the sand box can be adjusted through the combined sliding of the sand box frame structure, and then a small number of sand boxes can be used to meet the needs of casting product production in a large range; the design of the sand box can be reduced and production costs; at the same time, it can reduce the amount of molding sand, curing agent, and binder used in a single product, reduce production costs, and improve production efficiency.

Detailed ways

The present invention will be further described below in conjunction with accompanying drawing:

As shown in Figure 1, a kind of sliding type sand box comprises right angle frame 1, right angle telescopic block 2, length frame 3, long side sliding wall 4, width frame 5, wide side sliding wall 6, four right angle frames 1 and two A length frame 3 and two width frames 5 together form a rectangular frame structure. One side of the right-angle frame 1 is slidably connected to the length frame 3 through the horizontal slide rail 17; the other side is slid to the width frame 5 through the horizontal slide rail 2 8 Connection, on one side of the right-angle frame 1 and the corresponding position on the length frame 3, process a number of threaded holes-9, and use bolts-10 and different threaded holes-9 to cooperate to fix the relative position of the right-angle frame 1 and the length frame 3; On the other side, process some threaded holes 2 11 at the corresponding positions on the width frame 5, adopt bolts 2 12 and different threaded holes 11 to coordinate the relative position of the fixed right-angle frame 1 and the width frame 3; process the longitudinal section of the right-angle frame 1 with U-shaped groove 13, the right-angle telescopic block 2 is embedded in the U-shaped groove 13, and several threaded holes 14 are correspondingly processed on the right-angled frame 1 and the right-angled telescopic block 2, and the bolts 15 and different threaded holes 14 are used to cooperate to fix the right-angled frame 1 and The relative position of the right-angle telescopic block 2; the length frame 3 and the long-side sliding wall 4 are slidably connected by the vertical slide rail 16, and the corresponding positions on the length frame 3 and the long-side sliding wall 4 are processed with several threaded holes 4 17, and bolts 4 18 are used. Cooperate with different threaded holes four 17 to fix the relative positions of the length frame 3 and the long side sliding wall 4; Corresponding position is processed some threaded holes 5 20, adopts bolt 5 21 and different threaded holes 5 20 to coordinate the relative position of fixed width frame 5 and wide-side sliding wall 6. The long-side sliding wall 4 and the wide-side sliding wall 6 are also provided with a rib plate fixing frame 22, and a fixed rib plate 23 is installed as required to prevent deformation and sinking of the sand mold.

When using the sand box, the size of the sand box can be adjusted according to the needs. By adjusting the horizontal slide rail, adjust the relative positions of the right-angle frame 1, the length frame 3, and the width frame 5, and then use bolts to match the right-angle frame 1, length frame 3, and width frame 5. Fix the threaded holes on the sand box to adjust the inner diameter of the sand box; adjust the relative position of the right-angle frame 1 and the right-angle telescopic block 2 by adjusting the vertical slide rail, adjust the relative position of the length frame 3 and the long-side sliding wall 4, and adjust the width The relative position of the frame 5 and the wide-side sliding wall 6 is fixed by bolts matching the threaded holes of each component to adjust the height of the sand box, so that the height and inner diameter of the sand box can be adjusted to the required size, which can be adjusted to the minimum state , as shown in Figure 2, can also be adjusted to the maximum state, as shown in Figure 3, at the same time, the ribs 23 can also be installed as required, and the ribs 23 can be fixed to the ribs fixing plate 22 at the corresponding position, as shown in Figure 1 Shown to prevent the deformation and sinking of the sand mold.

The invention has an ingenious design structure, adjusts each part of the sand box through a sliding mechanism, and at the same time performs telescopic deformation in two directions, horizontal and vertical, so that the inner diameter and height of the sand box change, and the size of the sand box can be adjusted arbitrarily to realize a small number of sand boxes.
