Description

The glof club head model casting ceramic shell and the preparation method that contain filter

Technical field:

What the present invention relates to is the manufacture method of castable ceramic shell and shell thereof, specifically is a kind of glof club head precision-investment casting ceramic shell of filter and manufacture method of this shell of containing.

Background technology:

Golf is the fashion sports of an elegance, leisure, worldwide presents more and more prosperous development trend.Used equipment is made fineness, quality standard is strict, does not allow cast(ing) surface that any flaw is arranged.Have now in glof club head precision casting preparation technology, adopt traditional teeming formula pouring technology.Harmful substances such as the slag in the casting process in the liquid metals, oxide are easier to enter in the foundry goods, make foundry goods flaw occur, form a large amount of waste products, not only increase manufacturing cost, also seriously reduce production efficiency.Method by soldering is repaired cast(ing) surface, has reduced the quality of product, can't satisfy the presentation quality requirement.When employing is laid the hat screen pack at the cup place liquid metals is filtered since cup place liquid metals changes in flow rate big, unstable, easily splash, easily cause screen pack floating, break through phenomenon, be difficult to the filter effect that reaches desirable.And the liquid metals after filtering flows into casting mold by long distance, and active element still forms the secondary oxidation thing, does not reach the purpose of purification.At the bottom of the manufacture craft process complexity of its existing ceramic shell, the yield rate, be not suitable for the large-scale production manufacturing.

Summary of the invention:

The purpose of this invention is to provide a kind of glof club head model casting ceramic shell and preparation method who contains filter.Device of the present invention can filter removes harmful substances such as slag, oxide in the liquid metals, improves the glof club head cast properties, makes tensile strength, yield strength, percentage elongation improve 15～20%.Its preparation method can reduce manufacturing cost, enhance productivity, is fit to the large-scale production manufacturing.The present invention comprises ceramic case 1, and ceramic case 1 is made up of cup 1-1, die head 1-2, a plurality of ingate 1-3, a plurality of foundry goods chamber 1-4; The cup end mouth end of cup 1-1 connects the upper end charging aperture of die head 1-2, a plurality of lower ends discharging opening of die head 1-2 connects the upper end charging aperture of a plurality of ingate 1-3 respectively, the lower end discharging opening of a plurality of ingate 1-3 connects the upper end charging aperture of a plurality of foundry goods chamber 1-4 respectively, and it also comprises a plurality of filters 2; The outer edge part of filter 2 is embedded on the inwall of middle inside of ingate 1-3, makes ingate 1-3 be filtered device 2 and is divided into two cavitys up and down.Its preparation method is a, the die head mould 3 of making the band cup 1-1 and the 1-2 that gets to know, as Fig. 2; The Wax mold 4 of b, making band ingate 1-3 and foundry goods chamber 1-4 is provided with recessed conduit 1-5 outside the circle on the inwall of the middle part of the ingate 1-3 in Wax mold 4, the degree of depth of conduit 1-5 is 3mm～10mm, as Fig. 3; C, filter 2 is put into ingate 1-3, the outer edge part of filter 2 is embedded among the outer groove of the circle road 1-5 on the inwall of ingate 1-3, make ingate 1-3 be filtered device 2 be divided into about two cavitys, as Fig. 4; D, the wax that melts is poured into respectively in die head mould 3 and the Wax mold 4, treat wax cooling back removal die head mould 3 and Wax mold 4, obtain second wax-pattern 6, as Fig. 6 with first wax-pattern 5 (as Fig. 5) of cup 1-1, die head 1-2 and band ingate 1-3, filter 2, foundry goods chamber 1-4; E, several second wax-patterns 6 and one first wax-pattern 5 are connected into combination module 7, as Fig. 7; F, obtain module 8 after hanging fireproof coating, scab and carrying out drying being coated with on the outer surface of combination module 7, as Fig. 8; G, module 8 usefulness heat steams are melted wax material, then module 8 roasting at high temperature carry out potteryization, promptly obtain containing the ceramic case 1 of filter 2, as Fig. 1.Operation principle: metallic solution flows into from watering rim of a cup 1-1, metallic solution through get to know 1-2, a plurality of ingate 1-3, flow in a plurality of foundry goods chamber 1-4, through a plurality of filter 2 among a plurality of ingate 1-3 the time, metallic solution is filtered device 2 and filters.Device of the present invention can filter removes harmful substances such as slag, oxide in the liquid metals, improve the glof club head cast properties, make tensile strength, yield strength, percentage elongation improve 15～20%, improved the compactness of foundry goods behind the filtration, purification, greatly reduced surface blemish, help the enforcement of electroplating technology, and have advantage simple in structure, that cost is low.Its preparation methods steps is simple, operation easily, cost is low, efficient is high, yield rate is high, be fit to the large-scale production manufacturing, be beneficial to and apply.
