Problems solved by technology

Among them, the preparation cost of plaster mold and electrolytic copper mold is moderate, the process is simple, but the service life is low; and the alloy aluminum mold has a good service life and finished product quality, and the performance is stable; With a certain temperature, the plastic sheet is easy to stick to the working surface of the upper mold during the cooling molding process, which is not conducive to the demoulding of the product, thus affecting the quality and production efficiency of the plastic product

Embodiment 1

[0015] The specific preparation steps of the high-performance aluminum alloy blister mold mentioned in the present invention are as follows:

[0016] a) Material selection and preparation, the pretreatment process of the aluminum alloy mold includes: sandpaper grinding, degreasing treatment, water rinsing and drying, etc.; the sandpaper uses No. 1000 water sandpaper; the average particle diameter of the selected molybdenum disulfide particles is 2-2.5 um,

[0017] b) Preparation of electrophoretic deposition solution. The main components and percentage ratio of the electrophoretic deposition solution are: 7% molybdenum disulfide particles, 0.2% surfactant, and the rest is deionized water; triton solution is selected as the surfactant; The preparation process is as follows: Put the raw materials into the electromagnetic stirrer, control the rotation speed of the mixing drum at 400r / min, control the temperature of the mixing drum at about 35°C, and the time is about 1.2 hours; ...

Abstract

The invention discloses a preparation method of a high-performance aluminum alloy blistering mold. The preparation method comprises the following steps: (a) selecting and preparing materials; (b) preparing an electrophoretic deposition solution; (c) performing deposition; (d) performing after treatment of the mold. The invention discloses the preparation method of the high-performance aluminum alloy blistering mold; the preparation method is reasonable in procedure arrangement, simple and convenient in preparation process and moderate in cost; a molybdenum disulfide coating prepared on a working surface of the mold has the advantages of stable film forming property, high presentation quality and the like, so that the blistering mold is excellent in self-lubrication property, and the demolding efficiency and the finished product quality of a blister product are effectively improved.

Description

technical field [0001] The invention relates to a method for preparing a high-performance aluminum alloy plastic-absorbing mold, in particular to a method for preparing an aluminum alloy plastic-absorbing mold with self-lubricating performance, and belongs to the technical field of plastic-absorbing molding machine accessories. Background technique [0002] Blister molding machine is also called thermoplastic molding machine. Its working principle is: use the vacuum suction generated by the vacuum pump to heat and soften thermoplastic plastic sheets such as PVC, PET, PETG, APTT, PP, PE, PS, etc., through the mold suction. It can be molded into vacuum covers of various shapes, or attached to the surface of products of various shapes. The blister process can be divided into thin sheet blister and thick sheet blister according to the thickness of the sheet. [0003] The mold used on the blister forming machine is called a blister mold, which heats a flat plastic sheet to softe...
