目前生产加工的塑料盖板模具主要为以下几个阶段，分别是填充、宝压、冷却、脱模，在加工制
作中采用的是注塑机成型生产工艺，这里需要注意的是高速填充和低俗填充，保压阶段将注塑机里面
的压力控制在一个相当高的程度，这样可以使塑料表现出超强的可压缩性，在这个时候会不断增加注
塑机里面的压力，致使原材料的密度更高，起到很好的收缩和韧性。
At present, the plastic cover plate mold produced and processed mainly includes the
following stages: filling, pressing, cooling and demoulding. The molding production
process of the injection molding machine is adopted in the processing and production.
What needs to be paid attention to here is high-speed filling and vulgar filling. In the
pressure maintaining stage, the pressure in the injection molding machine is controlled
to a very high degree, This can make the plastic show super compressibility. At this
time, the pressure in the injection molding machine will continue to increase, resulting
in higher density of raw materials and good shrinkage and toughness.
对于塑料盖板模具的特点，其主要为轻质，易搬运、易施工等特点，而且模具的韧性比较好，在检修
维护清理期间，可以进行任意的翻动，能够很好的保证盖板模具外观的完整性，而且模具的表面光滑
规整，模具的尺寸也比较统一，模具具有易施工，尤其其它材料具有的特殊性，且用新型承重材料代
替钢筋，实现了可钉、可任意切割，模具的抗老化性能强，使用的期限也比较长。
For the characteristics of the plastic cover mold, it is mainly light, easy to handle,
easy to construct and so on. Moreover, the die has good toughness. During the maintenance
and cleaning, it can be arbitrarily flipped. It can ensure the integrity of the
appearance of the cover mold, and the surface of the mould is smooth and regular, and the
size of the die is relatively uniform. In particular, the particularity of other
materials, and the use of new load-bearing materials instead of reinforcing bars, can be
nailed and can be cut arbitrarily. The mould has strong anti-aging properties and the use
period is longer
对于混凝土盖板模具的制作是非常简单的，直接将混凝土倒入沟盖板模具之中，通过振动平台进行振
动，排除了混凝土里面的气泡使得水泥制品更加的有型和美观，同时混凝土盖板模具易脱模，光亮度
比较高，在如今的市场之中这类模具受到广泛的欢迎，模具采用工程聚丙烯经注塑机注塑成型，模具
在使用初期要注意保养，而且混凝土盖板模具一般生产程序质量都比较好。
The manufacture of the concrete cover plate mold is very simple. The concrete is directly
poured into the ditch cover plate mold and vibrated through the vibration platform to
eliminate the bubbles in the concrete, making the cement products more shaped and
beautiful. At the same time, the concrete cover plate mold is easy to demould and has
high brightness. This kind of mold is widely welcomed in today's market, The mold is made
of Engineering polypropylene and injection molded by injection molding machine. Attention
should be paid to the maintenance of the mold in the early stage of use, and the quality
of the general production procedure of the concrete cover plate mold is relatively good.
