The customization of imitation wooden piles needs to be done according to the customer's requirements, so we need to pay a lot of attention when making them. Manufacturers' imitation wooden piles usually have a significant sharp corner effect, which mainly refers to the stress concentration at the tip when the angle between two or three sides is less than 120 degrees. When the stress reaches a certain level, the tip is a part that is prone to cracking. Under continuous stress, the crack continues to expand, leading to crack propagation, resulting in fracture or cracking of the finished product. Therefore, how to avoid the crack effect in the design of imitation wooden piles?

仿木桩在确保正常释放前提模具注射过程应尽可能简单，易脱模，以避免或尽量减少围绕模具抽芯的各种装置。这不仅极大地简化了模具的结构，而且对注射成型模具，提高生产效率。在模制过程中，由于圆角，以避免应力集中，使用自定义的木模中，部件的强度，以确保角部的应力集中部，同时减少振动的分解产物。当时的受到应力或冲击。如果不恰当的或成形的结构部件不合理的条件，会产生大的变形量。强调特别容易发生应力开裂。

The injection process of the imitation wooden pile should be as simple as possible and easy to demould, in order to avoid or minimize the various devices surrounding the core extraction of the mold, in order to ensure normal release. This not only greatly simplifies the structure of the mold, but also improves production efficiency for injection molding molds. During the molding process, due to the use of rounded corners to avoid stress concentration, the strength of the components in the customized wooden mold is used to ensure stress concentration at the corners while reducing the decomposition products of vibration. At that time, it was subjected to stress or impact. If inappropriate or formed structural components are subjected to unreasonable conditions, significant deformation can occur. Emphasize that stress cracking is particularly prone to occur.

圆角是注塑模具制造商定制仿木护栏时避免尖角效应的佳方法之一，以满足不同物理机械性能的机器在使用中。主要要求产品紧凑，焊接强度高，强度高，内应力低。但在我们日常的注塑或测试过程中，即使对工艺参数进行适当的调整，产品也往往会出现填充不足、内应力高、表面流线等多种现象，主要原因是模具排气有问题。

Round corners are one of the best methods for injection mold manufacturers to avoid sharp corner effects when customizing wooden guardrails, in order to meet the needs of machines with different physical and mechanical properties in use. The main requirements are compact products, high welding strength, high strength, and low internal stress. However, in our daily injection molding or testing process, even with appropriate adjustments to process parameters, products often experience various phenomena such as insufficient filling, high internal stress, and surface streamline. The main reason is the problem of mold exhaust.

在仿木护栏注射制模的生产过程中，如果模具排气不良，模具型腔内的气体会受到挤压，产生较大的背压，严重影响了定制护栏的正常快速填充，给注塑带来困难。 同时，它将迫使注射制模压力增加，保温时间增加，注射制模周期延长，以及注射制模部分生产。

In the production process of injection molding for imitation wood guardrails, if the mold exhaust is poor, the gas in the mold cavity will be squeezed, resulting in significant back pressure, seriously affecting the normal and rapid filling of customized guardrails, making injection molding difficult. At the same time, it will force the injection molding pressure to increase, the insulation time to increase, the injection molding cycle to extend, and the production of injection molding parts.

为了使熔融塑料的流动性保持在良好的状态，在定制木材状屏障的过程中必须提高熔融塑料的温度和注入压力。但是如果压力增加，那么制品的残余也会随之增加，并且还会使塑料模具的裂痕增加。

In order to maintain the fluidity of molten plastic in a good state, it is necessary to increase the temperature and injection pressure of the molten plastic during the process of customizing a wood like barrier. But if the pressure increases, the residue of the product will also increase, and it will also increase the cracks in the plastic mold.
