Embodiment Construction

[0013] The present invention will be further described below in conjunction with the accompanying drawings and specific embodiments.

[0014] refer to figure 2 As shown, the casting mold of the present invention can be composed of more than one mold unit connected in series (shown in the figure is a perspective view showing the combination of two mold units), wherein each mold unit is composed of the first mold assembly 10 and the second mold unit respectively. Two mold components 20 are assembled, wherein the first mold component 10 and the second mold component 20 have the same shape and structure and are arranged symmetrically. Therefore, the first mold component 10 is taken as an example to introduce its structural features in detail.

[0015] Such as image 3 shows two first mold components 10 connected in series, the first mold component 10 includes a component body 11, the component body 11 includes a working surface 111 for splicing with the second mold component 20 ...

Abstract

The invention relates to a casting method of a grinding rod, which comprises the following steps: one or more first mould assemblies are connected in series to obtain a first mould assembly of the length of the grinding rod to be casted, the first mould assembly is provided with a work surface, and a first casting slot is formed along the axial direction of the work surface; one or more second mould assemblies are connected in series to obtain a second mould assembly of the length of the grinding rod to be casted, the second mould assembly is provided with a work surface, and a second castingslot is formed along the axial direction of the work surface; the first mould assembly and the second mould assembly which are assembled and connected in series enable work surfaces to be in mutual split joint, and the first casting slot and the second casting slot form a casting space; liquid steel is poured into the casting space from an opening of the casting space; and the grinding rod is manufactured after the liquid steel is cooled and formed. The method uses the series connection of a plurality of mould assemblies for casting, reduces the proportion of the length and the width of the mould in the casting process, and can overcome the breakage problem caused by heat expansion and cold contraction.

Description

technical field [0001] The invention relates to a casting method, in particular to a casting method of a grinding rod. Background technique [0002] Such as figure 1 As shown, it is a grinding rod used in a general grinding machine. This kind of grinding rod is placed in the grinding machine. The grinding machine rotates at a certain speed to drive the multiple grinding rods placed in it to roll, so that the large particles entering the grinding machine The material is broken; most of the current grinding rods are made by forging process, but the manufacturing cost of forging is very high, and the forging process is labor intensive, the working environment is poor, and the workpiece heating time is long; The casting technology has developed rapidly, and many casting processes have greatly changed the traditional casting methods. Not only the labor intensity is low, the operation is simple, but the working environment has also changed greatly compared with before; In the pa...
