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?

仿木樁在確保正常釋放前提模具注射過(guò)程應(yīng)盡可能簡(jiǎn)單，易脫模，以避免或盡量減少圍繞模具抽芯的各種裝置。這不僅極大地簡(jiǎn)化了模具的結(jié)構(gòu)，而且對(duì)注射成型模具，提高生產(chǎn)效率。在模制過(guò)程中，由于圓角，以避免應(yīng)力集中，使用自定義的木模中，部件的強(qiáng)度，以確保角部的應(yīng)力集中部，同時(shí)減少振動(dòng)的分解產(chǎn)物。當(dāng)時(shí)的受到應(yīng)力或沖擊。如果不恰當(dāng)?shù)幕虺尚蔚慕Y(jié)構(gòu)部件不合理的條件，會(huì)產(chǎn)生大的變形量。強(qiáng)調(diào)特別容易發(fā)生應(yīng)力開裂。

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.

圓角是注塑模具制造商定制仿木護(hù)欄時(shí)避免尖角效應(yīng)的佳方法之一，以滿足不同物理機(jī)械性能的機(jī)器在使用中。主要要求產(chǎn)品緊湊，焊接強(qiáng)度高，強(qiáng)度高，內(nèi)應(yīng)力低。但在我們?nèi)粘５淖⑺芑驕y(cè)試過(guò)程中，即使對(duì)工藝參數(shù)進(jìn)行適當(dāng)?shù)恼{(diào)整，產(chǎn)品也往往會(huì)出現(xiàn)填充不足、內(nèi)應(yīng)力高、表面流線等多種現(xiàn)象，主要原因是模具排氣有問(wèn)題。

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.

在仿木護(hù)欄注射制模的生產(chǎn)過(guò)程中，如果模具排氣不良，模具型腔內(nèi)的氣體會(huì)受到擠壓，產(chǎn)生較大的背壓，嚴(yán)重影響了定制護(hù)欄的正常快速填充，給注塑帶來(lái)困難。 同時(shí)，它將迫使注射制模壓力增加，保溫時(shí)間增加，注射制模周期延長(zhǎng)，以及注射制模部分生產(chǎn)。

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.

為了使熔融塑料的流動(dòng)性保持在良好的狀態(tài)，在定制木材狀屏障的過(guò)程中必須提高熔融塑料的溫度和注入壓力。但是如果壓力增加，那么制品的殘余也會(huì)隨之增加，并且還會(huì)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.
