快速公路防撞墻模具我國(guó)模具行業(yè)在荊棘中不斷前進(jìn)，技術(shù)支持，更多技術(shù)支持我國(guó)模具行業(yè)在荊棘中不斷前進(jìn)，我國(guó)防撞墻模具行業(yè)在荊棘中不斷前進(jìn)，為保證防撞墻模具零件的產(chǎn)量和模具外形尺寸穩(wěn)定，在大規(guī)模生產(chǎn)模具時(shí)應(yīng)采用高性能材料制造，并對(duì)材料外觀進(jìn)行低真空表面強(qiáng)化處理，其次模具形狀復(fù)雜，精度要求高，制造周期長(zhǎng)，因此模具生產(chǎn)過程中防撞墻鋼模具目前大幅增長(zhǎng)，促使模具行業(yè)向前邁進(jìn)了一大步。從模具的選擇方面來看，必須選擇有質(zhì)量保證的，以質(zhì)量為中心，提高模具的壽命等，考慮模具的室形、分型面、澆注位置和方式、排氣位置等，對(duì)模具的精度、形狀、復(fù)雜性、物理性質(zhì)有重要影響。

Expressway anti-collision wall mold China's mold industry is advancing in the thorns, technical support, more technical support, China's mold industry is advancing in the thorns, and China's national defense wall striking mold industry is advancing in the thorns

It is proved that the output of the anti-collision wall mold parts and the overall dimension of the mold are stable. In the large-scale production of the mold, high-performance materials should be used, and the material appearance should be subject to low vacuum surface strengthening treatment. Secondly, the mold shape is complex and the precision is high

High requirements and long manufacturing cycle, so the anti-collision wall steel mold in the mold production process has increased significantly, which has promoted the mold industry to take a big step forward. From the aspect of die selection, it is necessary to select the one with quality assurance to

Quality as the center, improve the service life of the die, and consider the chamber shape, parting surface, pouring position and mode, exhaust position, etc. of the die, which has an important impact on the accuracy, shape, complexity and physical properties of the die.
