Description

Sand mo (u) ld casting supports base

Technical Field

The utility model relates to a precoated sand casting technical field especially relates to a sand mold casting supports base.

Background

Sand casting is a widely used form of casting. The method comprises the steps of manufacturing a sand mould in advance, filling high-temperature resistant particles into a gap between the sand mould and a sand box after the sand mould is placed into the sand box, supporting the side wall of the sand mould, and then pouring molten metal into the sand mould. However, the sand mold is usually irregular in structure, the bottom of the sand mold has a groove structure, and the filled high-temperature resistant particles are difficult to fill the bottom of the sand mold. Therefore, each time of boxing, workers are required to repeatedly adjust the sand mould to ensure that the high-temperature-resistant particles are filled in the bottom of the sand mould to support the groove position of the sand mould. Otherwise, the groove structure at the bottom of the sand mold is suspended, and the condition of bottom leakage of the sand mold often occurs during pouring.

Drawings

Fig. 1 is the utility model provides a base is supported in sand mold casting's structural schematic diagram.

Fig. 2 is the utility model provides a side view structure sketch map of sand mould casting support base with sand box and sand mould complex.

Fig. 3 is the utility model provides a sand mould casting supports overlooking the schematic structure of placing the sand mould on the base.

Detailed Description

As shown in fig. 1 to 3, fig. 1 is that the utility model provides a structural schematic diagram of a sand mold casting support base, fig. 2 is that the utility model provides a sand mold casting support base on with sand box and sand mold complex structural schematic diagram that looks sideways at, fig. 3 is that the utility model provides a sand mold casting supports and places the overlooking structural schematic diagram of sand mold on the base.

Referring to fig. 1, the utility model provides a base is supported in sand mould casting, including pedestal 1, the 1 top of pedestal has the sand mould and places the position, the sand mould is placed and is equipped with the supporting shoe 11 that is used for carrying out the support to sand mould 10 bottom on the position.

In the specific use process of the sand mold casting support base of the embodiment, referring to fig. 2, the sand mold 10 is firstly placed on the sand mold placing position of the base body 1, the groove position at the bottom of the sand mold 10 is supported by the support block to avoid the bottom of the sand mold from being suspended, and then the sand mold 10 is placed into the sand box 20 together through the support base body.

In the embodiment, the sand mold casting support base is provided, wherein a sand mold placing position is arranged at the top of a base body, and a support block for supporting the bottom of a sand mold is arranged on the sand mold placing position; through the support base of above-mentioned optimal design, set up on the support base with the recess complex supporting shoe of sand mould, support the unsettled position in sand mould bottom, the condition that the sand mould warp and the under screen that has significantly reduced takes place, has improved the appearance quality of product greatly, fixes a position the sand mould position through the two cooperation simultaneously, has overcome the sand mould and has slided and shift to workman's intensity of labour and the work degree of difficulty have significantly reduced.

In a specific embodiment, the supporting base further comprises a plurality of hoisting rods 2, the hoisting rods 2 extend upwards from the base body 1 and are arranged around the sand mold placing position, and hoisting parts are arranged at the upper ends of the hoisting rods 2; the hoisting rod is used for conveniently putting the supporting base and the sand mold into the sand box 20 integrally before casting and taking the supporting base and the sand mold out of the sand box 20 integrally after casting.

In the concrete design of hoist and mount pole, hoist and mount pole 2 adopts the screw rod, and the screw rod lower extreme screw thread is installed on pedestal 1.

Because in the casting field, the sand mould often divide into case and nowel, some have one or more middle casees in addition, need the mould assembling before the pouring, for guaranteeing that the metal liquid of die cavity the inside can not outflow during the mould assembling, put forward higher requirement to the die joint laminating sealing degree of last nowel, but when actual operation, the condition of laminating not tight can avoid taking place, will follow the die joint gap that the sand mould contacted like this and ooze the metal liquid, commonly known as "run out fire". Therefore, in order to guarantee the reliability of the upper and lower die closing, the embodiment further comprises a gravity pressing plate 3, wherein the gravity pressing plate 3 is positioned above the sand mold placing position and compresses the upper and lower die closing through the gravity pressing plate.

Referring to fig. 3, in order to prevent the gravity clamp plate from moving when a sand mold is placed in the sand box 20, in other embodiments, the edge of the gravity clamp plate 3 has a positioning groove for engaging with the sand mold pouring gate 101, and the edge of the gravity clamp plate is positioned by engaging with the upper mold through the positioning groove.

In addition, the edge of the gravity pressing plate 3 is provided with a clamping piece 4 matched with the hoisting rod 2, the hoisting rod 2 is sleeved with a limiting nut 5 installed in a threaded manner, and the limiting nut 5 is positioned above the gravity pressing plate 3; on the one hand, the gravity pressing plate is matched with the hoisting rod through the clamping piece, the sand mold is bound on the supporting base, and the reliability during integral movement is guaranteed.

In other concrete implementation modes, the middle part of the gravity pressing plate 3 is also provided with a central hoisting piece 6, and the hoisting part on the hoisting piece and the hoisting rod is convenient for hoisting the base and the sand mould integrally.

The above description is only the specific implementation manner of the preferred embodiment of the present invention, but the protection scope of the present invention is not limited thereto, and any person skilled in the art can substitute or change the technical solution of the present invention and the design of the present invention within the technical scope of the present invention.
