The utility model provides a new type of feeding cold flow injection mold, which includes the upper and lower formwork and the mold core. The mold cavity is formed between the upper and the lower templates and the core. The injection layer comprises a glue injection hole, a cooling water pipe, an upper and lower injection plate with a plurality of injection grooves, and an injection slot at the beginning end of the injection slot, and the injection mouth is used as the injection port. The starting point is radiated outward, the end is connected with the rubber injection channel, and the cooling water pipe spacing array is arranged in the injection plate. The heating layer, including the heating plate, the heat insulation layer, including the heat insulation board, is located between the heating plate and the lower injection plate; the glue hole channel is connected with the mold cavity, and the heat insulation board and the cooling pipe can control the low temperature in the glue pass. At the curing temperature of the fluid, the fluid enters the mold cavity faster, reduces the waste of the raw material and improves the product's good product rate; the various positions of the mold cavity connected by multiple injection holes can make the raw material enter into the mold cavity synchronously and quickly fill the mold, the product has full shape and no defect, the good product rate is raised, the molding time is reduced, the molding time is reduced. Higher productivity. One

新型节料冷流道注射模具
本技术涉及新型节料冷流道注射模具。
技术介绍
目前,热固性工程材料因众多优良特性,应用领域广泛,在包括家电、办工及工业设备、汽车等行业得到应用,现有的热固性塑料一般是在在热流道模具中注塑成型,模具中热流道和分流道内的温度较高,在一个注射口内注塑液要分流至多个模腔,造成流道的整体长度较长,流体在热流道与分流道中受热固化,原料浪费严重,并且难以清理;同时由于分流道较长,导致流体在流道和分流道中流动阻力大,难以使流体充满模腔,进而造成生产出的产品成型不饱满,出现缺料、有气孔以及质量不稳定的技术问题,从而使得该种热流道模具中成型产品不良率较高,且质量不稳定;同时一般多采用单流道模具,流体经单流道进入模腔,难以快速充满模腔,产品在充满模腔的过程中,更易出现缺料及气孔的现象,造成产品质量不稳定,存在隐患。
技术实现思路
有鉴于此,本技术的目的是提供一种新型节料冷流道注射模具,具有提高产品良品率、快速充满模腔、产品外形饱满无缺陷、降低产品成型时间、减少原料浪费的优点。为解决上述技术问题,本技术的技术方案是:新型节料冷流道注射模具,包括上、下模板及型芯,上、下模板及型芯之间形成模腔,模具包括注射层,包括注胶孔道、冷却水管、设有多条注射槽的上、下注射板,注射槽起始端汇于一处形成注射口,且以注射口为起点向外辐射延伸,末端与注胶孔道连通,冷却水管间隔阵列式均布下注射板内;加热层,包括加热板,位于上模板与下注射板之间,多根加热管间隔阵列式均布加热板;隔热层,包括隔热板,位于加热板与下注射板之间;注胶孔道由上往下延伸,依次穿过下注射板、隔热板及加热板,与模腔连通。该 ...
