Abstract
The invention discloses a wet casting gate milling cutter. The wet casting gate milling cutter comprises a milling cutter, a wear resistant layer, and a mounting hole formed in the milling cutter, wherein the milling cutter is divided into a sprue milling area, a gate cup milling area and a base; the sprue milling area is peach-shaped; the sprue milling area and the gate cup milling area are both in arc transition; the sprue milling area is connected with the gate cup milling area through a curved surface section I inwards recessed from two sides; the gate cup milling area is connected with the base through a curved surface section II inwards recessed from two sides; the milling cutter is a single-piece cutter; and the maximum size of the sprue milling area is smaller than the minimum size of the gate cup milling area. The wet casting gate milling cutter has the advantages of simple structure, convenience for manufacturing, low production cost, high shaping pass percent and reduction of sand defect wastes in wet casting.
Description
Technical field
The present invention relates to a kind of milling cutter, be specifically related to a kind of green casting cast gate milling cutter.
Background technology
Along with, widely using of green casting Renovation on High Pressure Automatic Moulding Line, design, the making of cast gate milling cutter seem particularly important, the shape of the structures shape cup of milling cutter, by the quality of direct relation foundry goods and the production efficiency of foundry goods.Existing cast gate milling cutter as described in Figure 1 in the market, cast gate milling cutter adopts two panels cutter a right-angled intersection to be welded and more anxious in the transition of tool feeding direction, easily cause very large to lifting force in the course of the work, find in process of production: cast gate milling cutter, after the complete cast gate of milling, has column sand lump to drop in die cavity.Therefore sand lump can be caused directly to destroy upper impression; When mould turnover, sand lump rolls and die cavity may be caused to destroy in die cavity, moulding give up case rate raise; The problems such as foundry goods sand defect is more.
Summary of the invention
Technical problem to be solved by this invention is to provide that a kind of structure is simple, easy to make, low cost of manufacture, sand lump is there will not be to drop die cavity in the milling cutter course of work, moulding qualification rate is high, reduces a kind of green casting cast gate milling cutter of the sand defect waste product in green casting.
Technical problem to be solved by this invention realizes by the following technical solutions:
A kind of green casting cast gate milling cutter, it comprises milling cutter, wearing layer and the installing hole be arranged on milling cutter, described milling cutter is divided into sprue milling district, cup milling district and base, described sprue milling district is peach-shaped, described sprue milling district and cup milling district all adopt circular arc excessive, and the curved sections I that sprue milling district is concaved by both sides is connected with cup milling district, and the curved sections II that cup milling district is concaved by both sides is connected with base.
Described milling cutter is monolithic cutter.
Described sprue milling district full-size is less than cup milling district minimum dimension.
The invention has the beneficial effects as follows:
1) structure of the present invention is simple, easy to make, low cost of manufacture, is easy to realize, and there will not be sand lump to drop die cavity in the milling cutter course of work, moulding qualification rate improves greatly;
2) cup that mills out of the present invention and sprue round-corner transition, reduce the sand defect waste product in green casting largely.
Accompanying drawing explanation
Fig. 1 is prior art structural representation;
Fig. 2 is structural representation of the present invention.
Detailed description of the invention
The technological means realized to make the present invention, creation characteristic, reaching object and effect is easy to understand, below in conjunction with concrete diagram, setting forth the present invention further.
As shown in Figure 2, a kind of green casting cast gate milling cutter, it comprises milling cutter 1, wearing layer 2 and the installing hole 3 be arranged on milling cutter 1, milling cutter 1 is divided into sprue milling district 4, cup milling district 5 and base 6, and sprue milling district 4 is in peach-shaped, and sprue milling district 4 and cup milling district 5 all adopt circular arc excessive, the curved sections I that sprue milling district 4 is concaved by both sides is connected with cup milling district 5, and the curved sections II that cup milling district 5 is concaved by both sides is connected with base 6.
Milling cutter 1 is monolithic cutter.
Sprue milling district 4 full-size is less than cup milling district 5 minimum dimension.
Milling cutter 1 adopts a slice cutter, classification milling adopt arc transition, and the molding sand of intermediate alignment sprue first mills, smashes by the sprue milling district 4 at top, avoids just turning down to be blown by the sand lump that milling is logical because of blade thrust upwards flying; The curved sections I that sprue milling district 4 is concaved by both sides is connected with cup milling district 5, can realize the arc transition between cup and sprue.
More than show and describe general principle of the present invention and principal character and advantage of the present invention.The technical staff of the industry should understand; the present invention is not restricted to the described embodiments; what describe in above-described embodiment and description just illustrates principle of the present invention; without departing from the spirit and scope of the present invention; the present invention also has various changes and modifications, and these changes and improvements all fall in the claimed scope of the invention.Application claims protection domain is defined by appending claims and equivalent thereof.
