哪些因素会影响到检查井模具
What factors will affect the inspection well mold
检查井模具的特点在生产过程中,随着钢模具温度不断上升,当模温过热时,很容易产生粘膜,也会使运动部件失灵。标准型号的检查井钢模具型号为内径2米,外径2.3米的,立方数为9.42方,但是伴随着工程量加大,这种小立方的检查井构件无法满足生产的需要,所以卧式检查井模具进入市政工程领域的范围。
The characteristics of inspection well mould in the production process, with the continuous rise of steel mould temperature, when the mould temperature is overheated, it is easy to produce mucous membrane, which will also cause failure of moving parts. The standard model of inspection well steel mold is 2 meters in inner diameter, 2.3 meters in outer diameter and 9.42 cubic meters in cubic number. However, with the increase of work volume, this small cubic inspection well component can not meet the needs of production, so the horizontal inspection well mold has entered the scope of Municipal Engineering.
检查井模具还是方型的,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.这种检查井模具解决了传统检查井模具不耐腐蚀,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.检查井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.  充分的保障检查井模具顺利脱模。
The inspection well mould is square, the top and the bottom are slightly small, if they are separated, they are two trapezoids. When processing, two groove shaped models are processed first, and then they are combined together, which is a finished product. This inspection well mould solves the shortcomings of the traditional inspection well mould, which is not corrosion-resistant and easy to leak and plug, but the tightness is not good enough, and the compression resistance is general, so it is impossible to make large-scale production Products. The inspection well mold is basically a horizontal cylinder, but the top and bottom are still designed as a plane. The wheel shaped concave convex head is used. Because it is a cylinder mold, the products in this stage are generally connected and combined by butt joint. The compression resistance of this product is better than that of the first stage, but the tightness of the product can be improved, and the processing procedure of this product is complex, It is not conducive to factory production. It can fully guarantee the smooth demoulding of inspection well mold.
