注塑模具澆注（zhù）係統設計包括主流（liú）道的選擇、分流道截（jié）麵形狀及尺寸的確定、澆（jiāo）口的位置的選擇、澆口形式及澆口截（jié）麵尺寸的確定（dìng），當利用點澆口時，為了確保分流道的脫落還應（yīng）注意脫澆（jiāo）口裝置的設計、脫澆裝置和澆口機構。
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.
濟南注塑模具澆（jiāo）口位置選擇直接關係（xì）到產品成型質量及注射過程的順利進行（háng），澆口位（wèi）置的選擇應遵循以下原則：
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:
澆口位置應盡量選（xuǎn）擇（zé）在分型（xíng）麵上，以便於模具加工及使用時澆口的清理（lǐ）;
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;
澆口位置距型腔各個部位的距離應盡量一致，並使具（jù）流程為短;
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;
澆口的位置應保證塑料（liào）流入型（xíng）腔時，對型腔中寬暢（chàng），厚壁部位，以便於塑（sù）料順利流入;
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;
澆口位置應開設在塑件截麵厚處;
The gate position should be set at the thick section of the plastic part;
避（bì）免塑料在流下型腔時直衝型腔壁、型芯或嵌件，使塑料（liào）能盡快流入到型腔各部位，並避免型芯或嵌件變形;
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;
盡量避免使製品產生熔接痕，或使其熔接痕產生在製品不重要部位;
Try to avoid making the product produce welding lines, or making the welding lines produce in the unimportant parts of the product;
澆口位置及其塑料流入方向，應使塑料在流入型腔（qiāng）時，能沿著型腔平行（háng）的（de）方向（xiàng）均勻地流入，並有利於型腔內氣體的排出;
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;
澆口應設（shè）置（zhì）在製品上（shàng）易的部位，同時盡可能不影響產品外觀。
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.
