模具制造浇注零碎的设计
Design of Casting Fragments in Mold Manufacturing
1.浇注零碎设计包括主流道的选择、分流道截面外形及尺寸确实定、浇口的地位的选择、浇口方式及浇口截面尺寸确实定,当应用点浇口时,爲了确保分流道的零落还应留意脱浇口安装的设计、脱浇安装九章浇口机构。
1. Gating fragmentary design includes selection of main channel, determination of section shape and size of diversion channel, selection of gate position, gate mode and gate section size. When applying point gate, in order to ensure diversion channel fragmentation, attention should also be paid to the design of diversion gate installation and the installation of nine chapters gate mechanism.
2.在设计浇注零碎时,首先是选择浇口的地位。浇口地位选择间接关系到产品成型质量及注射进程的顺利停止,浇口地位的选择应遵照以下准绳:
2. In the design of casting fragments, the first step is to select the gate position. The selection of gate position is indirectly related to the quality of product moulding and the smooth stop of injection process. The selection of gate position should follow the following criteria:
3.浇口地位应尽量选择在分型面上,以便于模具加工及运用时浇口的清算。
3. The position of gate should be chosen on the parting surface as far as possible, so as to facilitate the clearing of gate in die processing and application.

4.浇口地位距型腔各个部位的间隔应尽量分歧,并使具流程爲短。
4. The gap between the gate position and each part of the cavity should be as different as possible, and the tool flow should be the shortest.
5.浇口的地位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。
5. The position of the gate should ensure that when plastic flows into the cavity, the cavity is wide and thick-walled, so as to facilitate the smooth flow of plastic.
6.浇口地位应开设在塑件截面厚处。
6. Gate position should be set at the thickest section of plastic parts.
7.防止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,并防止型芯或嵌件变形。
7. Prevent plastics from directly punching the cavity wall, core or insert when flowing down the cavity, so that plastics can flow into all parts of the cavity as soon as possible, and prevent the deformation of the core or insert.
8.尽量防止使制品发生熔接痕,或使其熔接痕发生在制品不重要部位。
8. Prevent as far as possible the occurrence of weld marks on products or the occurrence of weld marks on unimportant parts of products.
9.浇口地位及其塑料流入方向,应使塑料在流入型腔时,能沿着型腔平行的方向平均地流入,并有利于型腔内气体的排出。
9. The gate position and the direction of plastic inflow should enable the plastics to flow into the cavity equally along the parallel direction of the cavity, and be conducive to the discharge of gas in the cavity.
10.浇口应设置在制品上易肃清的部位,同时尽能够不影响产品外观。
10. Gates should be located in the most easily cleaned parts of the product, while doing everything possible not to affect the appearance of the product.
