Problems solved by technology

The molten iron buns poured into the front axle housing are generally more than 1m high and the molten iron capacity is 1.5t. If the sand mold of the upper box is formed by surrounding sand, the tightness of the sand is low. The sand breaks up, which leads to lifting the box and scrapping the casting; if the box sand mold is used for molding, it is first necessary to mix clay, sand, coal powder, water, etc. in proportion, and then use the molding machine to shape, not only the process is more complicated, but also the cost is high

Embodiment 1

[0015] Such as Figure 1~Figure 2 As shown, a sand box for casting a front axle housing, the length of the front axle housing is 1.8m~2m, the sand box includes an upper box body 1, a lower box body 2 and a connecting assembly, the connecting assembly includes a screw rod 3 and a nut 4 And the strip-shaped upper pressing plate and the lower pressing plate 7, the upper pressing plate includes the first upper pressing plate 5 and the second upper pressing plate 6 arranged in pairs, the first upper pressing plate 5 and the lower pressing plate 7 are respectively located on the upper side of the upper box body 1 and the lower box The lower side of the body 2 is arranged along the width direction of the box body. The second upper pressing plate 6 is located above the casting cavity and arranged along the length direction of the casting. The second pressing plate 6 is pressed by the first upper pressing plate 5. The two ends of the first upper pressing plate 5 and the lower pressing ...

Embodiment 2

[0019] It differs from Example 1 in that image 3 As shown, the four corners of the lower box are provided with L-shaped positioning plates 10, and the two side walls of the lower box 2 in the length direction are provided with inverted trapezoidal buffer grooves 11, and inverted trapezoidal buffer blocks 12 are installed in the buffer grooves 11. 12 is slid and guided by the guide post 13, and the guide post 13 is covered with a spring 14, and the two ends of the spring 14 are respectively against the bottom wall of the buffer block 12 and the buffer groove 11, and the buffer groove 11 is a non-penetrating structure along the thickness direction of the side wall, and the buffer A pair of limiting plates 15 are provided outside the slot 11 . The setting of the positioning plate can realize the fast positioning and closing of the upper and lower boxes, and the setting of the buffer block, spring and guide post can play a buffer role in the mold closing of the upper box and avoi...

Abstract

The invention provides a sand box for front axle shell casting. The sand box is suitable for an upper box sand mold formed by enclosing sand, avoids box lifting, guarantees the casting quality and reduces cost. The sand box for front axle shell casting comprises an upper box body, a lower box body and a connecting assembly, and is characterized in that the connecting assembly comprises a screw rod, a nut, a strip-shaped upper pressing plate and a strip-shaped lower pressing plate; the upper pressing plate comprises a first upper pressing plate and a second upper pressing plate which are arranged in pairs; the first upper pressing plate and the second upper pressing plate are arranged on the upper side of the upper box body and the lower side of the lower box body correspondingly and are arranged along the width direction of the box bodies; the second upper pressing plate is positioned above a casting cavity and is arranged along the length direction of the casting; the second pressingplate is pressed by the first upper pressing plate; long holes extending along the length direction are formed at the two ends of the first upper pressing plate and the lower pressing plate; and the two ends of the screw rod run through the long holes corresponding to the upper pressing plate and the lower pressing plate and then are locked by the nuts.

Description

technical field [0001] The invention relates to the field of sand casting, in particular to a sand box for casting a front axle housing. Background technique [0002] In the field of sand casting, the traditional sand box for castings generally includes an upper box, a lower box and a connecting assembly. , and bolts and nuts, the upper connecting seat and the lower connecting seat are locked by bolts and nuts after being matched with each other. The molten iron buns poured into the front axle housing are generally more than 1m high and the molten iron capacity is 1.5t. If the sand mold of the upper box is formed by surrounding sand, the tightness of the sand is low. The sand breaks up, which leads to lifting the box and scrapping the casting; if the box sand mold is used for molding, it is first necessary to mix clay, sand, coal powder, water, etc. in proportion, and then use the molding machine to shape, not only the process is more complicated, but also the cost is high ...
