在使用高速护坡模具时,常常会出现粘滞弯折的现象,使得人们很苦恼,可是该如何解决呢? 首先,我们先了解一下去成因。出现粘滞弯折的现象主要由于模具刚性不足,由于射出压力模具的膨胀鼓起引起的。型腔由于射出压力的作用多少会膨胀一点,如果是在六角六棱模具恢原状,但是实际上模具内的压力仍保持高的状态下使制品冷却固化,模具在恢复原状时用很大的力反作用于模具,使得模具不得不开启一点。所以,要对射出压力进行管理,不要上升到应设定的值以上。设置凹槽,强制调整。因对模具进行试模时容易发生,在模具上附加上千分表。一边监视一边慢升高射出压力。只有这样才能避免更多的粘滞弯折现象的发生。
When using high-speed slope protection molds, there is often a phenomenon of sticking and bending, which makes people very distressed. However, how to solve this problem? Firstly, let's first understand the causes. The phenomenon of viscous bending is mainly due to insufficient rigidity of the mold, which is caused by the expansion and bulging of the injection pressure mold. Due to the effect of injection pressure, the cavity will expand to some extent. If it is restored to its original state in a hexagonal and hexagonal mold, but the pressure inside the mold is still high, the product will cool and solidify. When the mold is restored to its original state, a large amount of force will be exerted on the mold, making it impossible for the mold to not open a little. So, it is necessary to manage the injection pressure and not increase it above the set value. Set grooves and force adjustments. Due to the high risk of mold testing, a dial gauge is attached to the mold. Monitor while slowly increasing and ejecting pressure. Only in this way can more viscous bending phenomena be avoided.
高速护坡模具的材料一般为透明或者半透明的塑料,如果其中夹杂着很多的黑色,红色,暗黄色斑点,而且表面的加工痕迹特别明显,则可以证明这个厂家生产的高速护坡模具根本就不符合要求。当然还要具有高耐腐蚀性,添加剂在很多塑料的使用,甚至化学作用使模具本身容量的都会腐蚀。要保证模具材料要****,因此,所需要的模具要具有高耐磨性,如果塑料模具不耐磨,模具很容易受到过度的磨损而变形。商家如果实现模具专业化生产,以提高模具质量,才能降低成本,推动模具的工作,提高竞争力。
The material of high-speed slope protection molds is generally transparent or semi transparent plastic. If there are many black, red, and dark yellow spots mixed in, and the surface processing marks are particularly obvious, it can prove that the high-speed slope protection molds produced by this manufacturer do not meet the requirements at all. Of course, it also needs to have high corrosion resistance. Additives are used in many plastics, and even chemical reactions can corrode the capacity of the mold itself. To ensure that the mold material is * * * *, the required mold must have high wear resistance. If the plastic mold is not wear-resistant, it is easy for the mold to deform due to excessive wear. If merchants achieve specialized production of molds to improve mold quality, they can reduce costs, promote mold work, and enhance competitiveness.
模具形状多样,拥有方便的可凑性,尺寸也是多种多样的,根据一定的数量与生产工艺选择铁模具.更加的实用。而且,随着我国经济飞速发展,交通运输成了制约经济的重要原因之一,所以公路铁路成了建设和发展成了国家亟待解决的问题,
Mold shapes are diverse, with convenient adjustability and a variety of sizes. Iron molds can be selected based on a certain quantity and production process, making them more practical. Moreover, with the rapid development of China's economy, transportation has become one of the important reasons restricting the economy, so the construction and development of highways and railways have become an urgent problem that the country needs to solve,
