Plastic turnover box series mould
(including plastic beer box mold, plastic water tank mold, plastic fruit box mold, storage box mold, storage box mold, plastic box mold, sealed box mold, etc.)
Commonly used mold steels are: 45#, 40Cr, P20, 2738, 2316, 718, NAK80, S136 and so on.
The turnover box mold is generally recommended to use 718, Shanghai Baosteel P20 material (because 718, Shanghai Baosteel P20 through our company's mold making process, not only can improve the life of the mold, but also increase the surface gloss of the product molded by the mold, while not There will be flash/burr.)
Mold cooling system design
The design of the cooling system is a relatively complicated work, that is, the cooling effect and the uniformity of the cooling should be considered, and the influence of the cooling system on the overall structure of the mold should be considered. The specific position and size of the cooling system are determined; Or cooling of the inserts; cooling of the side slides and side cores; design of the cooling elements and selection of cooling standard components. Our company began to analyze these series of problems during mold design. The mold uses circulating water to flow in every part of the mold, reducing the cooling time during injection molding, improving the production efficiency of the product and greatly reducing the production cost.
Mold maintenance is more important than mold maintenance. The more times the mold is repaired, the shorter the life is. The better the mold is maintained, the longer its service life will be. Mold maintenance is mainly divided into three points; Daily maintenance of the mold: various moving parts such as thimbles, rows, guide posts, guide bushings,
The cleaning of the die face, the dredging of the water, which is maintained every day when the mold is produced. 2. Regular maintenance: Regular maintenance, including daily maintenance, also requires the cleaning of the exhaust vents, trapping the black spots and exhausting, and repairing the damage and wear parts. 3. Appearance maintenance: paint on the outside of the mold base to avoid rust. When the lower mold is used, the fixed mold should be coated with anti-rust oil. When the mold is stored, it should be closed tightly to prevent dust from entering the cavity.
