电力检查井模具介绍：在采购的电力检查井模具的时,不能一味的贪图便宜,避免购买劣质电力检查井模具的风险。客户可以从以下个方面来检查：看电力检查井模具整体外观。看模具的整洁度,包括飞边,毛刺,拉伤等,要是有,说明产品在加工时没有做到位,质量也是不过关的；看壁厚。切开模具,看下产品的壁厚,如果壁厚很薄,那么制作电力检查井模具时容易变形和破；看颜色外观,必须选择色泽光亮,质地均匀的新料生产的模具。
Power inspection well mold introduction: when purchasing the power inspection well mold, we can't blindly covet the low price, to avoid the risk of purchasing poor quality power inspection well mold. Customers can check from the following aspects: see the overall appearance of the power inspection well mold. Look at the cleanliness of the mold, including flash, burr, tear, etc. if there is, it means that the product is not in place during processing, and the quality is not up to standard; the wall thickness is also considered. Cut the mold and look at the wall thickness of the product. If the wall thickness is very thin, it is easy to deform and break when making the electric inspection well mold. To see the color appearance, we must choose the mold produced by new material with bright color and uniform texture.
电力检查井模具质量与寿命,根据电力检查井模具结构不同,选择不同的定位方式,定位精度控制主要依靠加工,内模定位主要是设计者充分去考虑,设计出更加合理易调整的定位方式。电力检查井模具精度,即避卡、精定位、导柱、定位销等。定位系统关系到制品外观质量,浇注系统,即由注塑机喷嘴至型腔之间的进料通道,包括主流道、分流道、浇口和冷料流水槽模具 u型槽模具 电缆槽模具 隔离墩钢模具 护坡砖模具 钢制闸门 螺杆式启闭机 卷扬式启闭机穴。特别是浇口位置的选定应有利于熔融塑料在良好流动状态下充满型腔,附在制品上的固态流道和浇口冷料在开模时易于从电力检查井模具内顶出并予以清除。塑料收缩率以及影响制品尺寸精度的各项因素,如电力检查井模具制造和装配误差、电力检查井模具磨损等。
According to the mold structure of power inspection well, different positioning methods are selected according to the mold structure of power inspection well. The positioning accuracy control mainly depends on processing, and the internal mold positioning is mainly considered by the designer to design a more reasonable and easy to adjust positioning mode. The accuracy of electric power inspection well mould includes avoiding jamming, fine positioning, guide pillar, positioning pin, etc. The positioning system is related to the appearance quality of the product. The gating system is the feeding channel from the nozzle to the cavity of the injection molding machine, including the main channel, the diversion channel, the gate and the cold cavity. In particular, the selection of gate location should be conducive to the molten plastic filling the cavity in a good flow state, and the solid runner and gate cold material attached to the products are easy to be ejected from the power inspection well mold and removed during mold opening. Plastic shrinkage and various factors affecting the dimensional accuracy of products, such as manufacturing and assembly error of power inspection well mold, wear of power inspection well mold, etc
