【摘要】：现有汽车滤清器上壳体注塑模具成本高、效率低、塑件质量不易保障。针对此问题,开发的模具采用一模两腔布局,将型腔固定在定模板上,将型芯和附加板固定在动模板上。型芯与大侧抽芯及小侧抽芯组成组合型芯,共同形成塑件内表面形状。大侧抽芯在其抽芯方向可与型芯及小侧抽芯分离。小侧抽芯兼有侧滑块的作用,在斜导柱的作用下,沿附加板的导滑槽向斜上方作侧向抽芯。小侧抽芯被斜压板固定到附加板上。附加板为独立结构,其上开有导滑槽,且被固定在动模板上。结果表明:该注塑模具克服了一模两腔布局的大型模具制造成本高、维修不方便的弊端,使得多筋复杂型腔的大型模具制造和维修方便,降低生产成本,保证塑件的精度,提高生产率和模具的使用寿命。
[Abstract]:The injection mold of the shell on the existing automobile filter has high cost, low efficiency, and the quality of the plastic parts is not easy to be guaranteed. In order to solve this problem, the mould developed adopts the layout of one mold and two cavities, and the cavity is fixed on the fixed template. The core and the attached plate are fixed on the moving template. The core, the large side core pulling and the small side core pulling form the combined core, Forming the shape of the inner surface of the plastic parts together. The large side core pulling can be separated from the core core and the small side core pulling in the direction of the core pulling. The small side core pulling has the function of the side slider, under the action of the inclined guide column, Lateral core-pulling along the guide chute syncline of the attached plate. The small side core pulling is fixed to the attached plate by the oblique compression plate. The attached plate is an independent structure with a guide chute on the top. The results show that the injection mould overcomes the disadvantages of high manufacturing cost and inconvenient maintenance of the large mould with one mold and two cavity layout, and makes the manufacturing and maintenance of the large mould with multi-stiffened and complex cavity convenient and reduces the production cost. Ensure the precision of plastic parts, improve the productivity and the service life of the mould.
