注塑模具浇注系统设计包括主流道的选择、分流道截面形状及尺寸的确定、浇口的位置的选择、浇口形式及浇口截面尺寸的确定，当利用点浇口时，为了确保分流道的脱落还应注意脱浇口装置的设计、脱浇装置和浇口机构。
The design of injection mold gating system includes the selection of main runner, the determination of runner section shape and size, the selection of gate position, the determination of gate form and gate section size. When using point gate, in order to ensure the separation of runner, attention should also be paid to the design of de gate device, de gate device and gate mechanism.
济南注塑模具浇口位置选择直接关系到产品成型质量及注射过程的顺利进行，浇口位置的选择应遵循以下原则：
The gate position selection of Jinan injection mold is directly related to the product molding quality and the smooth progress of the injection process. The gate position selection should follow the following principles:
浇口位置应尽量选择在分型面上，以便于模具加工及使用时浇口的清理;
The gate position should be selected on the parting surface as far as possible, so as to facilitate the cleaning of the gate during mold processing and use;
浇口位置距型腔各个部位的距离应尽量一致，并使具流程为短;
The distance between the gate position and each part of the cavity should be as consistent as possible, and the tool flow should be short;
浇口的位置应保证塑料流入型腔时，对型腔中宽畅，厚壁部位，以便于塑料顺利流入;
The position of the gate should ensure that when the plastic flows into the mold cavity, the wide and thick wall parts in the mold cavity should be controlled to facilitate the smooth flow of plastic;
浇口位置应开设在塑件截面厚处;
The gate position should be set at the thick section of the plastic part;
避免塑料在流下型腔时直冲型腔壁、型芯或嵌件，使塑料能尽快流入到型腔各部位，并避免型芯或嵌件变形;
Avoid the plastic from directly punching the cavity wall, core or insert when flowing down the cavity, so that the plastic can flow into all parts of the cavity as soon as possible, and avoid the deformation of the core or insert;
尽量避免使制品产生熔接痕，或使其熔接痕产生在制品不重要部位;
Try to avoid making the product produce welding lines, or making the welding lines produce in the unimportant parts of the product;
浇口位置及其塑料流入方向，应使塑料在流入型腔时，能沿着型腔平行的方向均匀地流入，并有利于型腔内气体的排出;
The gate position and the plastic inflow direction should make the plastic flow evenly along the parallel direction of the cavity when flowing into the cavity, and be conducive to the discharge of gas in the cavity;
浇口应设置在制品上易清除的部位，同时尽可能不影响产品外观。
The gate should be set on the part of the product that is easy to remove, and at the same time, it should not affect the appearance of the product as much as possible.
