Fin mold maintenance is more important than mold maintenance. The more the mold is repaired, the shorter its life is; the better the mold is maintained, the longer its life will be.

 

The maintenance of the fin mold 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 are the daily maintenance 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 the mold is lowered, 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.

 

Commonly used fin mold steel selection

 

45#, 40Cr, P20, 2738, 2316, 718, NAK80, S136, etc. Generally, it is best to choose P20 and 2738 for the shell mold of fitness equipment. The price is reasonable, and the surface of the product can achieve a certain degree of smoothness. The internal requirements are high, especially the gears using 2316 and 718. If the quality of the mold is more guaranteed, you can choose NAK80.

 

Fin mold three-dimensional structure design, mold structure drawing design: good mold structure design is a prerequisite for a qualified mold manufacturing. The company’s technical department has 10 professional mold structure designers and product stylists, all of whom have more than 5 years of experience Work experience, can conduct all-round analysis of mold structure and product structure (including: mold demolding angle, product surface microcosm, gating system design, exhaust system design, cooling system design, etc.) These molds are also the most important The most prone problems will be repeated trial and error during mold structure design.

 

Fin mold design and processing

 

We will report and track the mold to the customer. After the mold material is purchased, I will send the picture to you. After the original processing is completed, I will send the picture to you, and then report to you when the mold is assembled, and then send the sample to you Yes, I will let you see our process throughout the process.

 

Design of cooling system for fin mould

 

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 influence 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 movable mold Or cooling of inserts; cooling of side sliders and side cores; design of cooling elements and selection of cooling standard elements. 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.
