高速护坡模具的质量并不全是厚度决定,并不是说厚度大了,模具就结实,这和模具的原材料还有一定的关系。模具的材质与质量是紧密相连的,材料的好坏决定着塑料模具的外观和质量。零件产量大、外形尺寸稳定的模具要采用高性能的材料制造,这类高速护坡模具材料还能进行低真空表面强化处理,让模具的耐用度提高到新的水平。
The quality of high-speed slope protection molds is not solely determined by the thickness, and it does not mean that a thicker mold will be sturdy, which is also related to the raw materials of the mold. The material and quality of the mold are closely related, and the quality of the material determines the appearance and quality of the plastic mold. Molds with high production capacity and stable external dimensions should be made of high-performance materials. These high-speed slope protection mold materials can also undergo low vacuum surface strengthening treatment, improving the durability of the mold to a new level.
温度在高速护坡模具制造过程中的影响是巨大的,它主要是体现在几个方面,我们都知道在高温条件下,塑料非常容易变形,所以对于壁厚不一致和形状复杂的高速护坡模具来说,经常会因为收缩不均匀而产生模具变形,生产水泥制品的时候影响使用。针对这一特点,合理的冷却系统是模具降温过程中受热均匀。模具在成型过程中,塑件与高速护坡模具接触的面的稳定性比不接触的地方更好。一旦以后由于材料刚度的需要,必须更改材料厚度时,模具就需要进行一定的修改。但是一般情况下,模具塑件的尺寸公差是不能低于收缩率的10%的,也就是说误差要控制在10%以内。
The influence of temperature on the manufacturing process of high-speed slope protection molds is significant, mainly reflected in several aspects. We all know that plastic is very prone to deformation under high temperature conditions. Therefore, for high-speed slope protection molds with inconsistent wall thickness and complex shapes, mold deformation often occurs due to uneven shrinkage, which affects the use of cement products during production. A reasonable cooling system for this characteristic is to ensure uniform heating during the cooling process of the mold. During the molding process, the stability of the contact surface between the plastic part and the high-speed slope protection mold is better than that of the non-contact area. Once the material thickness needs to be changed due to material stiffness in the future, the mold needs to be modified to some extent. However, in general, the dimensional tolerance of molded parts cannot be lower than 10% of the shrinkage rate, which means that the error should be controlled within 10%.
