The utility model discloses an injection mold for a suspension bottle, which belongs to the technical field of the preparation of infusion bottles. The injection mold of the bottle consists of a gate mold, a cavity mold, a bottom die and a mandrel. The mold is composed of a symmetrical two valve, and the top is matched with the gate die. The two modes form a ring cavity. The bottom end of the mold cavity is matched with the bottom die. The mandrel passes through the inner die of the bottom die and is conformed with the bottom die. The utility model simplifies the injection mold of the bottle billet, and divides the cavity die of the main structure of the molding bottle into two valves. When assembled, the mold cavity die is composed of two valves, and then the mold, the bottom die and the mandrel are fit into the forming cavity of the bottle billet. When the die is removed, the gate die is removed, the mold cavity die is divided into two valves, the bottom die is top out of the bottle billet, and the operation is simple square The die structure is simple, the number of components is small, and the parts are used in conjunction with the conical structure, and the positioning accuracy is high.

本技术涉及输液瓶的制备
,具体涉及一种吊瓶注塑模具。
技术介绍
塑料输液瓶多用于医疗,为了方便使用,在塑料输液瓶底安装吊环以使塑料输液瓶能够直接倒立悬挂,一般塑料输液瓶吊环通过焊接方式固定。现有模具生产的输液瓶吊环结构包括吊环、输液瓶连接件和输液瓶,输液瓶连接件将吊环和输液瓶连接起来,输液瓶连接件利用焊接的方法与输液瓶底部固定连接,在运输时将吊环贴在输液瓶底部与输液瓶连接件平齐;在使用时掰起吊环即可悬挂在输液架上。由于吊环和输液瓶分别在不同的模具上成型,则需要不同结构的模具,这增加了模具成本、生产厂房占地增加,劳动损耗量也大大增加,而且生产工艺变得更加繁杂。采用焊接的方式将吊环固定在输液瓶底部,容易出现焊接应力和焊接不牢,而装有注射液的输液瓶重量较大,容易出现吊环脱落的现象;另外焊接的过程增加了生产时长,降低了生产效率,而且污染环境。专利文献CN103350484A公开了一种PP大输液吊环一体式瓶坯注塑模具,它包括浇口模仁、底模、型腔、模唇、注芯套和注芯,浇口模仁内部开设有浇注熔腔,浇注熔腔的底部设置有注胶口,型腔设置于底模的下方,型腔内侧的上部设置有型腔通孔;注芯套套装在模唇的下侧,注芯套内部设置有注芯套通孔,注芯套通孔内部套装有注芯,注芯的上部依次穿过模唇通孔、型腔通孔并延伸至底模的下部,浇口模仁的底部、底模、型腔、模唇和注芯配合形成的空间为瓶坯成型腔。该结构的瓶坯注塑模具能将吊环与瓶坯一体成型,减少了吊环的成型模具,而且不需焊接,降低了劳动强度,制造成本大幅度降低。但是多腔模具对冷却均匀性要求极高,当各个成型腔温度有差异时瓶坯 ...
