Description

TECHNICAL FIELD

[0001] The utility model relates to mould technical field, and specifically is high stable spring guide pillar mould. BACKGROUND

[0002] In the traditional mould design, especially in the injection and drawing forming process, the precision and stability of the mould often have a significant impact on the quality of the formed product. In some existing mould systems, the gap between the mould guide pillar and the guide sleeve is large and uneven, which can cause the mould to be misaligned during operation, thereby affecting the quality of the formed product. Especially in the drawing forming process, the gap between the upper die and the lower die of the mould is too large, which can easily cause the product to have uneven wall thickness during forming, affecting the strength and stability of the product.

[0003] Especially when the mould is frequently moved during the forming process, the uneven gap between the upper die and the lower die can cause the mould to not fit accurately, thereby affecting the coaxiality and wall thickness uniformity of the product. In severe cases, this uneven wall thickness can cause product quality problems, such as inconsistent drawing wall thickness, or problems such as poor machine running during customer use, directly affecting the product's performance and customer satisfaction

[0004] In addition, the stability and precision of the mould are also one of the key factors affecting the quality of the product. During long-term use of the mould, due to frequent mould closing and mould opening, the various components of the mould are prone to wear and deformation, thereby affecting the precision and stability of the mould. In addition, the process of maintaining and replacing parts of the mould is usually tedious and time-consuming, increasing the downtime of the production line and maintenance costs.

[0005] In the prior art, many mould guide pillars adopt a fixed structure, or the cooperation between the guide pillar and the mould is rough, causing instability during mould closing and mould opening, which can easily cause the mould to be misaligned accurately, thereby affecting the quality of the formed product. In addition, the frictional resistance of the guide pillar is large, causing the movement of the mould to be not smooth, reducing the service life of the mould. SUMMARY
