Embodiment Construction

[0027] In order to illustrate the technical solutions of the present invention more clearly, the present invention will be further described in detail below with reference to specific embodiments. Please note that the embodiments described below are exemplary only for explaining the present invention and should not be construed as limiting the present invention.

[0028] The pattern in casting refers to the process equipment or consumable parts that simulate the shape of the casting to form the mold cavity; in order to ensure the formation of the cavity that meets the requirements, the pattern should have sufficient strength, rigidity and appropriate surface accuracy and dimensional accuracy. When molding a large cylinder block mold, the large cylinder block is divided into the upper part of the cylinder block, the middle ring of the second cylinder block, the middle ring of the first cylinder block, and the lower part of the cylinder block. The mold is difficult to form, the ...

Abstract

The invention relates to a pattern for casting, in particular to a pattern capable of being lifted and used for a large cylinder body. The pattern comprises a pattern main body, a lifting auxiliary component, a movable material and a counterweight piece; the pattern main body comprises a wood component and a steel body component, and the steel body component comprises a component main body and a plurality of lifting parts; the component main body is arranged in an inner cavity of the wood component, the first end of the lifting part is connected with the component main body, and the second end of the lifting part extends out of the inner cavity of the wood component; the movable material is detachably connected to the upper side of the wood component; the second end is connected with a lifting pad; the lifting auxiliary component is connected to the upper part of the lifting pad and is matched with the lifting pad for lifting; the counterweight piece is arranged on the pattern main body. The pattern can efficiently lift a middle ring of the large cylinder block mold, is easy to operate and low in difficulty, cannot damage a sand mold and the mold easily, and effectively improves the dimensional stability of the casting and prolong the service life of the mold.

Description

technical field [0001] The present invention relates to a casting pattern, in particular to a pattern having a forming function suitable for a large cylinder block. Background technique [0002] Large cylinders usually weigh more than 10 tons and have dimensions larger than 4m*3m*1.5m. The blanks of large cylinders are usually castings, and the most common molding method for castings is wood mold sand casting. Due to the large size of large cylinder castings, when using template modeling, the template cost is high and it is easy to deform, so it is usually produced without template modeling. And usually the casting direction is to choose the middle flange face down, and the middle flange face as the parting surface. At the same time, limited by the lifting weight of the crane in the factory, easy to operate and based on safety considerations, the parting method usually adopts the method of upper type + lower type + more than 1 middle ring. [0003] In the prior art, large...
