【Mold knowledge】
Plastic spoon mold design
Good mold structure design is the prerequisite for qualified mold manufacturing. Our company's technical department has 10 professional mold structure designers and product stylists, all of whom have more than 5 years of work experience, and can comprehensively design mold structures and product structures. Aspect analysis (including: mold draft angle, product surface microcosm, pouring system design, exhaust system design, cooling system design, etc.) The main and prone problems of these molds will be tested repeatedly during the mold structure design.
Plastic spoon mold steel
Commonly used mold steel choices: 45#, 40Cr, P20, 2738, 2316, 718, NAK80, S136, etc. Generally, it is better to choose P20 and 2738 for plastic cup molds, which are reasonably priced and can also achieve a certain smoothness on the surface of the product. For those with high internal requirements, especially gears, 2316 and 718 are used. If you want to ensure the quality of the mold, you can choose NAK80.
Equipment introduction
It has a complete set of processing equipment, including 8 CNC milling machines (one of which is high-speed milling, the accuracy can reach 0.1mm), 3 EDM machines that can reach 0.1mm, 4 precision carving machines (one of which is slope carving), and 3 large drilling machines. , 4 wire cutting machines, a surface grinder that can reach 0.02mm, and a milling machine.
Plastic spoon mold cooling system design
The design of the cooling system is a relatively complicated task, which requires consideration of the cooling effect and uniformity of cooling, as well as the impact of the cooling system on the overall structure of the mold. The specific location and size of the cooling system must be determined; key parts such as the movable mold Or the cooling of inserts; the cooling of side sliders and side cores; the design of cooling components and the selection of cooling standard components. Our company began to analyze these series of problems when designing the mold. The mold uses circulating water to flow in every part of the mold, reducing the cooling time during injection molding, improving product production efficiency, and greatly reducing production costs.
☆Mold maintenance
Mold maintenance is more important than mold repair. The more times the mold is repaired, the shorter its lifespan; and the better the mold is maintained, the longer its service life will be. Mold maintenance is mainly divided into three points:
1. Daily maintenance of the mold: refueling of various moving parts such as ejector pins, rows, guide posts, and guide sleeves, cleaning of the mold surface, and clearing of water transport are all daily maintenance during mold production.
2. Regular maintenance: In addition to daily maintenance, regular maintenance includes cleaning of the exhaust slot, exhausting the trapped air and burning black spots, and repairing damaged and worn parts.
3. Appearance maintenance: Paint the outside of the mold base to avoid rust. When lowering the mold, the fixed and movable molds should be coated with anti-rust oil. The mold should be closed tightly when stored to prevent dust from entering the cavity.
