Embodiment 1

[0035] Embodiment 1: When a group of steel balls needs to be produced, it is the same as conventional casting at this time, that is, two modular monomers 1 are used for casting. Close the two modular monomers 1, at this time, the cavity 2, sprue 7, sprue 6, runner 4, ingate 5, overflow port 8 and overflow between the two modular monomers 1 The grooves 3 are closed one by one to form a complete casting channel, cavity and overflow channel; the molten iron is injected into the module body 1 through the sprue formed by two sprues 6, and the gas in the cavity passes through the overflow Outlet 8, bottom injection casting, molten iron flows upward from the runner 4 at the bottom, and fills the complete cavity one by one. When the molten iron overflows from the overflow port 8 into the overflow tank 3, the casting of the cavity is completed . After the molten iron is cooled, the module monomer 1 is disassembled, the rough mold is taken out, and redundant waste materials are removed...

Embodiment 2

[0036] Example 2: When it is necessary to produce multiple groups of steel balls, suppose the number of module monomers 1 is S, and the number of steel ball groups is n, that is, S=n+1, n=1, 2, 3... ..n. Taking two sets of steel balls as an example, such as Figure 4 As shown, the three modular monomers 1 are superimposed in sequence. At this time, the two sides of the middle module monomer 1 respectively form a complete casting channel, cavity and overflow channel, that is, two complete casting channels are formed on both sides of the middle module monomer 1. The casting system; the molten iron is injected into the three module bodies 1 through two complete casting ports, and the gas in the cavity is discharged upwards through the overflow port 8, bottom injection casting, and the molten iron flows upwards from the runner 4 at the bottom flow, filling the complete cavities one by one, when the molten iron overflows from the overflow port 8 into the overflow tank 3, that is, ...

Abstract

The invention discloses a two-sided casting mold of steel ball stack boxes. The two-sided casting mold comprises module monomers, wherein a plurality of half cavities arranged in lines are formed in the front and back side surfaces of the module monomers; the half cavities in the same lines are connected through ingates; straight gates are formed in the middles of the front and back side surfaces of the module monomers; cross gates perpendicular to the straight gates are formed in the bottom ends of the straight gates; and the top ends of the cross gates are communicated with the ingates in the bottoms of the cavities. The cavities, the inner cross gates and the straight gates are formed in the front and back sides of one module monomer, that is, the two sides can be cast; and the plurality of module monomers are stacked in the production to form the plurality of complete cavities for casting, so that the usage amount of the module monomers is largely decreased, and the production cost is largely reduced.

Description

technical field [0001] The invention relates to the field of casting technology, in particular to a casting mold, in particular to a steel ball stacked double-sided casting mold. Background technique [0002] Casting molds are needed in the production process of steel balls. The traditional casting method generally adopts sand casting, that is, sand molds need to be made first when pouring; when sanding, the mold moves more times, and the utilization rate of molten steel is low, and the finished product The smoothness is low, the sand falling phenomenon is serious, and the pouring time is long. In order to solve these problems, sandless casting molds are mostly used at present. But existing casting mold generally comprises left and right two formworks, and mold cavity and sprue are provided relatively in the middle part of two formworks, and two formworks are closed up during pouring, promptly adopts the mode of left and right mold closing, completes pouring by sprue.
