便道砖模具正确使用方法

     为了便于塑料制品从模具中脱出,并防止便道砖模具脱模时擦伤制品表面,在与开模方向平行的塑料制品表面均应有合理的脱模斜度。其斜度的大小取决于塑料的收缩率、塑料制品的形状、壁厚度及其部位等。一般情况下,脱模斜度为30°-45°。当塑料制品有特殊要求或精度要求较高时,应选用较小的斜度;沿开模方向塑料制品尺较大的部位,也宜选用较小的斜度;塑料制品形状复杂,厚壁及不易脱模时,应取较大的斜度;侧面有皮革花纹或加强助的制品,斜度取得更大。在开模时,为了让塑料制品留在模具的某一侧,则应将该侧的成型零件的斜度做得小一些,而另一侧斜度稍大一些。

In order to facilitate the removal of plastic products from the mould and prevent the scratch of the surface of the product when the brick mould is demoulded, the surface of the plastic products parallel to the direction of the mould opening should have a reasonable demoulding slope. The slope depends on the shrinkage of plastic, the shape of plastic products, the thickness of the wall and its position. Generally, the demoulding slope is 30 - 45. When plastic products have special requirements or higher precision requirements, smaller inclination should be selected; along the direction of opening moulds, smaller inclination should also be selected for larger parts of plastic products; when plastic products are complex in shape, thick wall and difficult to demould, larger inclination should be adopted; when leather pattern or reinforced products are on the side, the inclination can be obtained. Larger. In order to keep the plastic products on one side of the mould, the slope of the forming part on the side should be smaller, while the slope on the other side should be larger.

便道砖模具的正确使用方法是:

The correct way to use the mould for the brick is as follows:

    1、首先要有合理的施工场地,要均匀铺放护坡砖塑料模具,经行水泥注入。

    1. First of all, there must be a reasonable construction site. The plastic moulds of slope protection bricks should be laid evenly and injected with cement.

    2、合理的使用润滑油或者专用的脱模剂进行脱模以此来减少模具的磨损情况。

    2. Reasonable use of lubricant or special demoulding agent for demoulding in order to reduce the wear of the die.

    3、一般成型时间为24小时,之后经过振动平台或者振动棒经行辅助脱模。

    3. Generally, the forming time is 24 hours, and then assistant demoulding is carried out through vibration platform or vibration bar.
