注塑模具澆注系統(tǒng)設(shè)計(jì)包括主流道的選擇、分流道截面形狀及尺寸的確定、澆口的位置的選擇、澆口形式及澆口截面尺寸的確定，當(dāng)利用點(diǎn)澆口時(shí)，為了確保分流道的脫落還應(yīng)注意脫澆口裝置的設(shè)計(jì)、脫澆裝置和澆口機(jī)構(gòu)。
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(jì)南注塑模具澆口位置選擇直接關(guān)系到產(chǎn)品成型質(zhì)量及注射過程的順利進(jìn)行，澆口位置的選擇應(yīng)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(yīng)盡量選擇在分型面上，以便于模具加工及使用時(shí)澆口的清理;
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;
澆口位置距型腔各個(gè)部位的距離應(yīng)盡量一致，并使具流程為短;
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(yīng)保證塑料流入型腔時(shí)，對(duì)型腔中寬暢，厚壁部位，以便于塑料順利流入;
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(yīng)開設(shè)在塑件截面厚處;
The gate position should be set at the thick section of the plastic part;
避免塑料在流下型腔時(shí)直沖型腔壁、型芯或嵌件，使塑料能盡快流入到型腔各部位，并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;
盡量避免使制品產(chǎn)生熔接痕，或使其熔接痕產(chǎn)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;
澆口位置及其塑料流入方向，應(yīng)使塑料在流入型腔時(shí)，能沿著型腔平行的方向均勻地流入，并有利于型腔內(nèi)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(yīng)設(shè)置在制品上易的部位，同時(shí)盡可能不影響產(chǎn)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.
