Description
技术领域 technical field
本发明涉及一种吹塑成型模具,具体是指用卧式吹塑成型方式成型汽车油管的一种汽车油管的卧式吹塑成型模具及其吹塑成型方法。The invention relates to a blow molding mold, in particular to a horizontal blow molding mold for automobile oil pipes formed by horizontal blow molding and a blow molding method thereof.
背景技术 Background technique
现有技术汽车油管的吹塑成型沿袭立式吹塑成型塑料瓶的方式,立式吹塑成型塑料瓶为,挤出机挤出的熔融塑料经吹气模头吹成直径小于成品塑料瓶直径的筒状气泡形坯料,气泡借助重力下垂,嵌入立式装置的合符模具的二爿设有瓶子外形的型腔中,合符模具合模,再经吹气,鼓起气泡的泡壁附着在模具型腔壁上,经冷却,气泡成型为中空的塑料瓶;塑料瓶采用立式吹塑成型是为了利用重力使气泡自然下垂,便于气泡嵌入模具合模成型,然而,由于汽车油管是弯曲的,其投影区域大大地大于其实体投影尺寸,沿袭立式吹塑成型油管使得气泡坯料必须覆盖油管制品的投影区域,合模成型后,在油管实体二侧由成型模具分型面形成的连成整体的大面积的飞边,因而需要再通过切边模具切除飞边,飞边切除后在油管制品上留下切痕,而切下的飞边则被送去粉碎、造粒处理,且作再生料降级使用。飞边切痕不仅影响油管的外观质量,因切痕处管壁厚薄不均,还影响油管结构的机械强度质量,在使用中易发生破损泄漏事故;另外,飞边的再生处理增大了能耗,且再生料降级使用使新料损耗严重,增高了制品成本;因此,现有技术存在质量不良、泄漏事故隐患、成本居高、能耗大、原料浪费严重的问题与不足。In the prior art, the blow molding of automobile tubing follows the method of vertical blow molding of plastic bottles. The vertical blow molding of plastic bottles is that the molten plastic extruded by the extruder is blown by the blowing die to make the diameter smaller than the diameter of the finished plastic bottle. The cylindrical bubble-shaped blank, the bubbles droop with the help of gravity, and are embedded in the cavity of the bottle shape in the second valve of the vertical device, which conforms to the mold. On the wall of the mold cavity, after cooling, the air bubbles are formed into hollow plastic bottles; the vertical blow molding of plastic bottles is to use gravity to make the air bubbles sag naturally, so that the air bubbles can be embedded in the mold and molded. However, because the automobile oil pipe is curved The projected area is much larger than the projected size of the solid body. Following the vertical blow molding tubing, the bubble blank must cover the projected area of the tubing product. Integrate a large area of flash, so it is necessary to cut off the flash through a trimming mold. After the flash is removed, a cut mark will be left on the tubing product, and the cut flash will be sent to crushing, granulation, and processed. Recycled materials are downgraded for use. Flash cut marks not only affect the appearance quality of the oil pipe, but also affect the mechanical strength and quality of the oil pipe structure due to the uneven thickness of the pipe wall at the cut mark, which is prone to damage and leakage accidents during use; Consumption, and the downgrading of recycled materials leads to serious loss of new materials and increases the cost of products; therefore, the existing technology has problems and deficiencies such as poor quality, hidden dangers of leakage accidents, high cost, high energy consumption, and serious waste of raw materials.

采用卧式模具有利于机械手将直径小于油管制品直径的中空管状坯料直接装入下模2的弯曲的下半爿型腔中,在合模型腔中完成吹塑成型,成型时不产生飞边,从而避免了立式模具成型时形成飞边带来的诸多弊端。The use of a horizontal mold is beneficial for the manipulator to directly load the hollow tubular blank with a diameter smaller than the diameter of the tubing product into the curved lower half cavity of the
