Description

Technical Field

[0001] The present application relates to the field of sand molds, and specifically, to a 3D printed sand mold for an intercooler. Background Art

[0002] Sand mold is a casting cavity made of raw sand, binder and other auxiliary materials in the casting production process. Because the molding materials used in sand casting are cheap and easy to obtain, the mold is easy to manufacture, and it can adapt to the single-piece production, batch production and mass production of castings. For a long time, it has been the basic process in casting production. In order to facilitate the production of the casting cavity inside the sand mold, 3D printing of the part mold is usually used, and the sand mold is made through the mold.

[0003] The patent with application number 202022019009.0 discloses a 3D printing sand mold with an ejection structure, including a mounting seat, a base plate and a first plug rod, a base is installed above the base plate through a base, and a mounting seat is installed at the middle position of the top end of the base, a lower mold seat is installed at the bottom end inside the mounting seat, and the top end of the lower mold seat extends to the top of the mounting seat, an upper mold seat is arranged at the top of the lower mold seat, and a mold core is provided at the bottom end of the upper mold seat and the top end of the lower mold seat, mounting grooves are provided on both sides of the lower mold seat inside the mounting seat, and second plug rods are provided on both sides of the mounting seat, and one side of the second plug rod extends to the inside of the mounting groove, and by starting the cylinder to work, the cross plate is pushed to move, driving the ejector rod to move toward the inside of the mold core, so that the ejector rod can quickly eject the cast mold to assist the staff in taking it.

[0004] In the above structure, the upper mold and the lower mold of the sand mold are kept fixed by a locking mechanism. Since the adjusting rod needs to be turned to tighten and fix during the fixing process, the fixing method of the adjusting rod is similar to that of a bolt, and there is still a risk of lateral sliding of the upper mold after the adjusting rods on both sides are fixed, resulting in poor stability of the sand mold installation and poor convenience of use.

The content of this application is not intended to identify the key features or essential features of the technical solution claimed for protection, nor is it intended to limit the scope of the technical solution claimed for protection.

[0006] In order to solve the technical problems mentioned in the above background technology part, some embodiments of the present application provide a 3D printed sand mold for an intercooler, including a lower mold and an upper mold detachably fixed to the top of the lower mold; the lower mold and the upper mold are both provided with sand mold grooves on one side facing each other, and a second protrusion is symmetrically fixed to the top of the outer wall of the lower mold, and a first protrusion corresponding to the second protrusion is fixed to the outer wall of the upper mold, and a first connecting part and a second connecting part are respectively provided on the first protrusion and the second protrusion, and a connecting block is fixed to the top of the second connecting part, and both ends of the connecting block are elastically plugged with card blocks abutting against the top of the first connecting part.

[0007] The first protrusion and the second protrusion are respectively fixed on the upper mold and the lower mold, and the upper mold and the lower mold are fixed by the first protrusion and the second protrusion. During casting, the connecting block on the second connecting part fits through the connecting groove in the first connecting part, and the inclined groove on the side wall of the block abuts against the inner wall of the connecting groove, thereby squeezing the block to shrink into the telescopic groove. After the block passes through the first connecting part, the spring in the telescopic groove pushes the block to protrude from the top end of the first connecting part and is tightly connected to the top of the first connecting part, thereby keeping the upper mold and the lower mold fixed, and after casting, the block is squeezed to shrink into the telescopic groove, thereby removing the connecting block from the connecting groove, facilitating the installation and disassembly of the sand mold, and improving the stability of the installation of the sand mold and the convenience of disassembly.

[0008] Furthermore, a base is fixedly mounted on the bottom end of the lower mold, and a plurality of bolts are mounted on the top end of the base in a rectangular array.

[0009] Furthermore, a casting hole is provided at the top of the upper mold, and an intercooler mold is embedded in the sand mold groove.

[0010] Furthermore, a connection groove is provided at the center of the first connection portion, and the connection block is inserted into the connection groove.

[0011] Furthermore, the connection block is protrudingly arranged at the top end of the first protruding portion, and telescopic grooves are symmetrically provided at the top end of the connection block extending out of the first protruding portion.

[0012] Furthermore, a spring is embedded in the telescopic slot, and two ends of the spring are respectively in contact with the inner wall of the telescopic slot and the block.

[0013] Furthermore, the clamping block is slidably inserted in the telescopic slot, and one end of the clamping block protrudingly abuts against the inner wall of the telescopic slot.

[0014] Furthermore, an inclined groove is formed at one end of the clamping block extending out of the telescopic groove, and the inclined groove abuts against the inner wall of the connecting groove.

[0015] The beneficial effect of the present application is that the first protrusion and the second protrusion are respectively fixed on the upper mold and the lower mold, and the upper mold and the lower mold are fixed by the first protrusion and the second protrusion. During casting, the connecting block on the second connecting part fits through the connecting groove in the first connecting part, and the inclined groove on the side wall of the block abuts against the inner wall of the connecting groove, thereby squeezing the block to shrink into the telescopic groove. After the block passes through the first connecting part, the spring in the telescopic groove pushes the block to protrude from the top end of the first connecting part and is tightly connected to the top of the first connecting part, thereby keeping the upper mold and the lower mold fixed, and after casting, the block is squeezed to shrink into the telescopic groove, thereby removing the connecting block from the connecting groove, facilitating the installation and disassembly of the sand mold, and improving the stability of the installation of the sand mold and the convenience of disassembly.
