Abstract

The invention provides a powerful anti-cracking aluminum alloy plastic suction mold and a preparation method thereof, and relates to the technical field of plastic suction mold production. The plasticsuction mold is made of the following raw materials including, by weight, 1.5%-2.0% of copper oxide, 0.3%-0.7% of iron, 0.08%-0.12% of chromium, 0.5%-1.0% of manganese, 0.01%-0.03% of vanadium, 0.4%-0.8% of germanium, 0.2%-0.5% of strontium, 0.06%-0.10% of titanium dioxide, 0.06%-0.08% of a light rare earth element, 2.5%-3.0% of alumina fibers, 1.5%-2.0% of wollastonite fibers and the balance aluminum and inevitable impurities. By means of the powerful anti-cracking aluminum alloy plastic suction mold and the preparation method, the deficiencies in the prior art are overcome, the bonding force between components in the raw materials can be effectively improved, the anti-cracking capacity of the plastic suction mold can be effectively improved, influences of mold cracking on normal use areprevented, the strength, compactness and wear resistance of the plastic suction mold can be effectively improved, the overall performance of the plastic suction mold is excellent, the service life islong, and the powerful anti-cracking aluminum alloy plastic suction mold and the preparation method are suitable for promotion.

Description

technical field [0001] The invention relates to the technical field of plastic-absorbing mold production, in particular to a powerful crack-resistant aluminum alloy plastic-absorbing mold and a preparation method thereof. Background technique [0002] Blister is the abbreviation of blister forming, also known as vacuum forming, which is a processing technology of thermoplastics. The main principle is to clamp the sheet or plate material on the frame of the vacuum forming machine, heat and soften it, then pass through the air channel on the side of the mold, and use vacuum to absorb it on the mold, and after a short period of cooling, the formed plastic is obtained. products. The blister process can be divided into thin sheet blister and thick sheet blister according to the thickness of the sheet. Blister products are widely used in industries such as electronics, electrical appliances, food, hardware tools, cosmetics, toys, daily necessities, medicine, health care products...
