雨水化粪池模具还是方型的,顶部和底部略小,若是将其分开就是上下两个梯形.加工时先加工出来两个凹槽状的模型,再把它们合在一起,即成为一个成品.
The mould of rainwater septic tank is square, the top and bottom are slightly small. If it is separated, it will be two trapezoidal. When processing, first process two groove shaped models, and then combine them together to form a finished product
这种化粪池模具解决了传统化粪池模具不耐腐蚀,易渗漏堵塞的缺点,但是严密性还不够好,抗压性也一般,无法制作大型产品.雨水化粪池模具基本为横卧的圆柱体,但顶部和底部还是设计为平面.车轮状凹凸面封头开始使用.因为是筒状模具,这一阶段的产品一般采用对接的方法连接结合.这种产品的抗压性能要比第一阶段的好,但是产品的严密性还可以再加以改良,而且这种产品的加工程序复杂,不利于工厂化生产,充分的保障化粪池模具顺利脱模。
This kind of septic tank mold solves the shortcomings of traditional septic tank mold, which is not resistant to corrosion and easy to leak and block. However, the tightness is not good enough and the compression resistance is also general, so it is unable to make large products. The rainwater septic tank mold is basically a horizontal cylinder, but the top and bottom are still designed as flat surface. The wheel shaped concave convex head is used, The products in this stage are usually connected by butt joint method. The compressive performance of this product is better than that of the first stage, but the tightness of the product can be further improved. Moreover, the processing procedure of this product is complex, which is not conducive to factory production, which fully ensures the smooth demoulding of septic tank mold.
