Description
The present invention relates to a kind of with aluminium alloy by one-time formed ice-cream mould of ice-cream of die casting and manufacture method thereof.
Along with the ice cream appearance of (or claiming the ice fruit), it has become one of indispensable cold drink, particularly time in midsummer in people's life.But, can make the mould of ice cream freeze forming also the same with ice cream itself, experienced slow and very long development.Up to the present, the general ice-cream mold of China is still and adopts traditional artisan craftsmanship to make.Its common manufacture method is: be raw material with the copper plate, through stretching, punching press will be done the heat treatment that eliminates stress before the distortion repeatedly in addition at every turn, like this under expect machine-shaping, it is 0.6～1.2 millimeter ice-cream mould of ice-cream that wall thickness will just can be processed into through 15 procedures at least in front and back.In the manual process of this backwardness, waste product in the middle of which procedure is made a fault and all can be produced.Therefore, the ice-cream mould of ice-cream made from such method, not only complex process, percent defective height, and also quality also is difficult to guarantee.Yet,, so again the monotubular mould is welded on the framework with soldering one by one even if an also monotubular mould just of the ice-cream mould of ice-cream of machine-shaping is to be one group with per 30 monotubular moulds because make the used mould of ice cream.Owing to will be immersed in moulding in the freezing liquid (bittern or salt solution) to mould when cooking ice cream, therefore many weld bonds, weld seam and abominable condition of work and being difficult to guarantees mould quality and service life made from said method, so snapping and crack phenomenon of mould often occur in the production process of ice cream.In case when above-mentioned situation occurring, bittern or salt solution just can infiltrate in the ice cream, thereby cause ice cream sometimes to have bitter taste or saline taste.This is not only endangering the healthy of consumer, also can one group of mould all be scrapped because of a mould damages.In addition, because the present price of copper plate is comparatively expensive, add the ice-cream mould of ice-cream made from above-mentioned method with such raw material, its cost is just unknown.
Extrusion process is a comparatively advanced non-ferrous metal extrusion process of rising the sixties, and it not only has advantages such as production efficiency height, good product quality than the foundry goods with normal pouring, and can also satisfy the characteristic requirement of specialities.And as ice-cream mould of ice-cream, it had both required its material to have good thermal conductivity, anti-corrosive properties, also will guarantee the certain intensity when its pattern thickness must not be greater than 1.2 millimeters simultaneously, be that extremely difficulty satisfies the characteristic requirement of ice-cream mould of ice-cream with conventional pouring procedure or other materials therefore.(wall thickness＜3mm) still belongs to a brainstorm subject of world's die casting industry to the die casting thin-wall part in the latter stage seventies, the Bu Le brother company of the mid-80 Switzerland (die casting specialized company) has reached the thin-wall part of 1mm wall thickness, later on again and does not find to have new progress.By China machinery publishing house publish " technical specification in the Special Processes of Metal Castings handbook, general foundry goods area is at 25～100cm
2The time wall thickness also should be between 1.5～4.5mm, moreover the projected area of every ice-cream mould of ice-cream is 26.65cm
2According to the regulation of Japan's " Denso worker machine design standard ", the die casting wall thickness of aluminium alloy can not be less than 1mm.This shows that the desired 0.8～1mm wall thickness of ice-cream mould of ice-cream is " forbidden zone " in the aluminium alloy castings really.
The purpose of this invention is to provide a kind of ice-cream mould of ice-cream made from aluminium alloy.
The object of the present invention is achieved like this: said ice-cream mould of ice-cream factory is the ice-cream mould of ice-cream that adopts the aluminium alloy compression casting method to make.
The process of making this ice-cream mould of ice-cream is: this ice-cream mould of ice-cream adopts the ZL104 aluminium alloy after fusing, in holding furnace, be preheating to 300～450 ℃ through 750～770 ℃ of insulations, casting moulds, 720～750 ℃ of cast temperatures, injection ratio pressure is at 1260～1275kg/cm
2But, again through holding of 1～3 second press and 8～12 seconds prolong pressure just die sinking release the ice-cream mould of ice-cream base.But after remove the mouth of a river, burr and the just copper facing that is up to the standards, zinc-plated, integral solder, until the ice-cream mould of ice-cream that goes out finished product.
Reach embodiment below with reference to the accompanying drawings and be described in detail mould structure of the present invention and manufacture method thereof.
Fig. 1 is a flow process vertical view of making aluminum alloy die casting with conventional method.
Fig. 2 is that schematic diagram cuts open in the office of Fig. 1.
Fig. 3 is the flow process schematic top plan view of aluminium alloy compression casting ice-cream mould of ice-cream of the present invention.
Fig. 4 is that schematic diagram cuts open in the office of Fig. 3.
Shown in Fig. 1～2, Given this product is used the not problem of easy-formation of the casting mould of Fig. 1～2 and flow process because of wall is thin, Mould design will consider that at first the structure of mould and parting line select, and purpose is the melt flow process that will as far as possible shorten in the forming process, makes it can rapid shaping.Resemble shown in Fig. 1～2 by the existing conventional design, the mould of moulding ice-cream mould of ice-cream is that the ground of ining succession is arranged, liquation during die casting just enters the ingate of that mould of termination from sprue 1 through minute running channel 2 and ingate 3, under die casting, make liquation along ingate one by one the terminad mould expand.But because the obstruction of the special thin and pattern core 4 of the die wall of this product, and the common flow process of liquation in mould is long and heat loss that cause is excessive, sometimes liquation in addition all do not enter in the middle of mould in just solidified, so ratio of briquetting is extremely low.Test by repeatedly, grope to sum up,, just must improve mould and running channel flow process if will address the above problem.
Shown in Fig. 3～4: this mould is that the special shape characteristics according to ice-cream mould of ice-cream design, and it has changed some conventional methods for designing, employing be: the method for rising pouring side depoling.Rising pouring is exactly to leave ingate 3 from the mould bottom of ice-cream mould of ice-cream, extracts pattern core 4 out in the side of mould.This method is six ice-cream mould of ice-cream of a die casting, and six moulds divide two to arrange flat crouching, and three of every rows connect together, and sprue 1 and main running channel 5 are in the centres of two row's moulds, and ingate 3 at the bottom of each mould of UNICOM and branch running channel 2 communicate with main running channel 5.This design mainly solves such two problems: the flow process of 1. as far as possible shortened the master, dividing running channel, strengthened the master, divided the sectional area of running channel, cast gate and air discharge duct.Because this foundry goods wall is special thin, spillway discharge is less during pressure injection, moulding is fast, only make the moment flow of liquation strengthen, accelerate, just can make the filling of mould inner melt full, so when mould is made, must suitably increase the width and the degree of depth of exhaust duct, casting gas (gas in die cavity and the molten metal) is discharged, rapidly in order to avoid cause (gas) defective on the foundry goods.After discharging gas and regulus according to vigorous front end, the theory that foundry goods begins moulding from ingate is so the slag trap of this mould is opened end at die cavity-be the edge of ice cream die orifice.Calculate the diameter=casting section thickness of mold running channel * 20mm(coefficient by existing conventional is theoretical), running channel can only be like this: 0.8 * 20=16mm
2, the design after improving then is decided to be running channel: 1.0 * 30=30mm
2 Slide block 6 and Angle Pin 7 on new die, have also been adopted in addition.
Narrate process characteristic of the present invention according to the extrusion process flow chart below.Its extrusion process flow process is as follows: melt → be installed the injection pressure → pressurize → mould → pickup of moving of boosting → water of mould → mould and die preheating → spray paint → matched moulds.The material of selecting for use of ice-cream mould of ice-cream is the ZL104 aluminium ingot, and fusing smelting technology and equipment routinely carries out.When aluminium liquid reaches 760～780 ℃, just put into the holding furnace insulation, the temperature of insulation is at 750～770 ℃, and the process of the mould that is installed is exactly having cleared up mould (mould employing 3Cr in place one by one
2The W8V alloy tool steel), then its preheat temperature is controlled at 320～450 ℃, wherein optimum temperature is 350 ℃, again to mould spray sodium fluoride coating.Die casting machine is selected J1125(250t for use) horizontal casting machine, with φ 50 shot piston, the about 144cm of total projection area of ice-cream mould of ice-cream
2, injection ratio pressure is at 1260～1275kg/cm
2Penetrate and press temperature at 730～750 ℃, every mold pressing firing rate degree is 1.0～1.1m/s, mould can be opened in 1～3 second of pressurize, extracts core rod.So far the ice-cream mould of ice-cream blank that is connected as a single entity with three monotubulars has just formed.
Blank just can carry out copper facing, zinc-plated processing, to prevent the etch of freezing liquid to die body after the assay was approved through simple cleaning, the removal mouth of a river and burr.At last 10 row's loose patterns are connected with soldering that just to have formed 30 tubes together be one group ice-cream mould of ice-cream factory, and its die wall thick only be 0.8～1.0mm.Anticorrosion except that take above-mentioned copper facing, zinc-plated, can also be with the integrated gasification oxide-film, ooze anti-corrosion measures such as anti-corrosion element and physical chemistry vapour deposition.
Technology of the present invention is simple, one-shot forming and yield rate height, its cost and weight only are equivalent to 1/3rd of red copper template die, and its service life red copper template die head and shoulders above. Because its cast is three and is connected as a single entity, thus its no weld bond, and weld seam also lacks more than three times than grand master pattern. Simultaneously, because its body has gently also alleviated ice cream direct labor's labour intensity greatly.
