Breast pump injection mold troubleshooting method

by:Vowin Rapid Prototyping     2023-02-03
What are the troubleshooting methods for the injection mold of the breast pump? The precise size and complete structure of plastic parts need to be mass-manufactured and processed through injection molds. Therefore, the quality of injection mold directly affects the quality and production efficiency of plastic parts. However, the manufacturing and processing procedures of injection molds are cumbersome. Shanghai Mulan Injection Mold Factory has high technical requirements for mold engineers and mold processing masters, and failures are prone to occur if you are not careful. Timely troubleshooting and solving problems can ensure the production cycle of injection molding. So, what are the troubleshooting methods for breast pump injection molds?

1. Difficult gate stripping: The main reason for this is that the smoothness of the gate taper hole is poor, or the raw material for injection molding is too soft, resulting in deformation or damage to the small end of the taper hole after the mold has been used for a period of time. It is recommended to choose standard parts as much as possible during mold manufacturing and processing, and be sure to set up a gate pulling or gate ejection mechanism;

2. Guide post damage: The guide post plays a guiding role in the mold to ensure that the core and the cavity molding surface will not collide under any circumstances, so when designing the guide post in the mold, it cannot be used as a force-bearing part or a positioning part;

3. Bending of the movable formwork: Steel should be selected for the movable formwork, and the thickness can meet the needs of injection molding processing. If necessary, support columns or support blocks can be designed under the movable formwork to facilitate the reduction of the thickness of the formwork and improve the bearing capacity;

4. Poor cooling: The design of the mold cooling system directly affects the quality of injection molding of the breast pump. If the cooling is not good, it will cause uneven shrinkage and warping. The design of the mold cooling system must not be ignored, it needs to be designed according to the shape and quality of the breast pump.

The above is a brief introduction of Shanghai Mulan Injection Mold Factory about 'breast pump injection mold troubleshooting methods'. There are many possible failures of breast pump injection molds, so I won't list them here. When manufacturing and processing breast pump injection molds, it is necessary to conduct a comprehensive evaluation based on breast pump quality requirements, mass production quantity, and service life requirements, and then make a reasonable design, so that the produced molds can achieve high quality and high cost performance.
