Paint Barrel Mould

Plastic bucket mould:

Including plastic food bucket mold, chemical bucket mold, paint bucket mold, anti-theft lid plastic bucket mold, pail mold, bucket mold, packaging bucket mold, trash can mold, etc.


Commonly used mold steels are: 45#, 40Cr, P20, 2738, 2316, 718, NAK80, S136 and so on. It is generally recommended to use 45#, Shanghai Baosteel P20 material for plastic barrel molds

1. Good mold structure design is the prerequisite for the manufacture of a qualified mold. The mold structure and product structure can be analyzed in all aspects (including: mold demolding inclination, product surface microcosm, gating system design, exhaust system Design, cooling system design, etc.) The most important and most prone problems of these molds will be trial and error during mold structure design.

2. mold cooling system design The design of the cooling system is a relatively complicated task, that is, the cooling effect and uniformity of the cooling must be considered, and the impact of the cooling system on the overall structure of the mold must be considered. The specific location and size of the cooling system are determined ; Key parts such as the cooling of the movable mold or the insert; the cooling of the side slider and the side core; the design of the cooling element and the selection of the cooling standard element. 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 to reduce the cooling time during injection molding, improve product production efficiency, and greatly reduce production costs.

3. Mold maintenance Mold maintenance is more important than mold repair. The more the mold is repaired, the shorter its lifespan. The better the mold is maintained, the longer its lifespan will be. Mold maintenance is mainly divided into three points: 1. Daily maintenance of the mold: various moving parts such as thimble, row position, guide post, guide sleeve refueling, mold surface cleaning, and water drainage, which are maintained every day during mold production. 2. Regular maintenance: Regular maintenance includes the cleaning of the exhaust slot in addition to the daily maintenance, the air trapping and the black level and the exhaust, and the correction of damage and wear parts. 3. Appearance maintenance: Paint the outside of the mold base to avoid rust. When lowering the mold, the fixed mold and the movable mold should be coated with anti-rust oil. The mold should be closed tightly to prevent dust from entering the cavity.
