井盖模具选用的工程聚丙烯pp为原料,这种原材料属于塑料制品,本身的重量比较轻,同时这种井盖模具质量一般都是按照尺寸规格比例去确定的。
The engineering polypropylene PP is selected as the raw material for the well cover mold, which belongs to the plastic products, and its weight is relatively light. At the same time, the quality of the well cover mold is generally determined according to the size and specification proportion.

井盖模具精度包括模具整体组合和零、部件的位置与形状尺寸精度、配合精度与定位精度.井盖模具设计时需进行严格的尺寸精度设计与计算.
The precision of the well cover mould includes the overall combination of the mould, the position and shape dimensional accuracy of the parts and components, the matching accuracy and the positioning accuracy. The design of the well cover mould needs to be strictly designed and calculated

同时,还须考虑零、部件的制造工艺性和工艺精度,,以保证井盖模具的精密性能和可靠性.井盖模具运动方向的导向,是由导向装置来保证的.
At the same time, the manufacturability and precision of parts and components must be considered to ensure the precision performance and reliability of the well cover mould. The guide device is used to ensure the movement direction of the well cover mould

同时,导向装置对井盖模具间隙的均匀性,****合模运动还起定位的作用.井盖模具企业要明确自己的助攻方向、加强之间的互相合作,及时有效地对客户的需求做出良好正确的反应。
At the same time, the guiding device also plays a role in positioning the gap uniformity and accurate mold closing movement of the well cover mold. The well cover mold enterprise should make clear its own assist direction, strengthen mutual cooperation, and make a good and correct response to the needs of customers timely and effectively.
