Abstract
The present invention relates to a lubricant for die cavities and punch heads, which are used for the die casting of aluminium alloy. The lubricant mainly uses cylinder oil which is matched with graphite and/or machine oil, wherein the proportions of the cylinder oil and the graphite by weight percentage are respectively from 80 to 95% and from 5 to 20%, the proportions of the cylinder oil and the machine oil by weight percentage are respectively from 55 to 80% and from 20 to 45%, and the proportions of the cylinder oil, the graphite and the machine oil by weight percentage are respectively from 70 to 90%, from 5 to 20% and from 10 to 30%. The lubricant can also be matched with beeswax, hydraulic oil and/or paraffin wax and/or animal oil and/or silicone oil and/or chloroparaffin and/or various petroleum additives. The dosage is different according to the viscosity of lubricating oil, the thicker the viscosity in need is, the more the dosage is, and the reverse is true. The lubricant can well lubricate die cavities and punch heads, reduce product pull and prolong the service life of the punch heads. In addition, the lubricant which has low cost can effectively replace imports.
Description
Technical field
The invention belongs to lubricate and use the petrochemicals technical field, be specifically related to be used for aluminium alloy compression casting die cavity and the lubricated lubricant of drift.
Technical background
The die cavity of aluminium alloy compression casting and drift must lubricate to guarantee that its equipment reduces wearing and tearing, and equipment is run well, and increase the service life, and also guarantee the quality of product simultaneously.Aluminum current alloy die cast industry has following several method to die cavity and drift lubricated:
1, full-automatic pressure die-casting machine: adopt the import special fat, though effect is good, the price height generally will be about 30-80 unit/kilogram more.
2, the old-fashioned pressure die-casting machine of the homemade or import of part: what have uses gun oil, have with beeswax, butter etc., though price is low, weak effect, product easily turn black, pull, drift is short work-ing life.
3, few general pressure die-casting machine of part home-made: what have use used oil, have in addition use pitch, effect is relative just poorer, and the pyrolysis products that has also may produce carcinogenic substance.
Summary of the invention
The present invention is directed to the die cavity and the lubricated deficiency of drift of existing aluminium alloy compression casting, be to provide a kind of aluminium alloy compression casting die cavity that utilizes locomotive oil, graphite and/or machine oil to be made into, drift lubricant at present for main raw material, it can play good lubricating effect to die cavity and drift, reducing product pulls, improve drift work-ing life, and price is low, effectively import substitutes.
Technical solution of the present invention is as follows:
It is main that aluminium alloy compression casting die cavity, drift lubricating oil adopt locomotive oil, is equipped with graphite again, and the weight percent of locomotive oil and graphite assembly is respectively 80%-95% and 5%-20%.
Need at the difference of the new used equipment of difference is lubricated, on the basis of above-mentioned prescription, also contain beeswax.Further also contain hydraulic efficiency oil and/or paraffin and/or animal oil and/or silicone oil and/or clorafin and/or various petroleum additive, the content of mentioned component all is the difference according to the required viscosity of lubricating oil, and required viscosity is thick more, and content is many more, otherwise few more.
Pressure die-casting machine die cavity and drift can produce very high temperature at work, the die cavity temperature can reach 350-400C in general, and the drift temperature is up to 500-550C, the present invention is based on locomotive oil, be because its heat resistance in lubricating oil is best, the flash-point height, heatproof reaches as high as 450C, can partly satisfy the needs of die cavity, drift.Selecting graphite simultaneously for use, is that 900 ℃ can both reach good lubricant effect in air because graphite is high temperature solid lubricant preferably, and both mix, and can respectively get the chief, satisfies pressure die-casting machine die cavity and the drift needs of effectively lubricating at high temperature.
At the adding mode difference of lubricant, as clamp-on, spray into, mode such as brushing, lubricating oil needs different viscosity, so the present invention has selected the specific machine oil of power lubrication is mixed with locomotive oil, regulates with the different viscosity to this product.
The present invention is the viscosity adjustment that is conceived to this product to selecting for use of beeswax, hydraulic efficiency oil, paraffin, animal oil, silicone oil, clorafin and various petroleum additives, can select its one or more for use according to different particular cases.
The a plurality of producers of this product are on probation for a long time, reflect respond well.Its major advantage is good to die cavity and drift lubricant effect, reduces product and pulls the work-ing life that can improve equipment, improve the quality of products, and price is lower than external like product, alternative imported product.
Embodiment
Embodiment:
This lubricant master joins can adopt following several concrete mode:
1. locomotive oil 9.5Kg graphite 0.5Kg
2. locomotive oil 10Kg beeswax 2Kg graphite 1Kg
3. locomotive oil 10Kg beeswax 3Kg graphite 1.5Kg
4. locomotive oil 8Kg beeswax 2Kg lard 1Kg graphite 1Kg.
