Description
技术领域technical field
本发明涉及热塑加工技术领域，尤其是指一种在热塑加工过程中，固定热流道系统主灌咀的隔热式法兰结构。The invention relates to the technical field of thermoplastic processing, in particular to a heat-insulating flange structure for fixing a main filling nozzle of a hot runner system during thermoplastic processing.
背景技术Background technique
随着石油产品的大行其市（如塑料、合成橡胶等），使得热流道加工快速兴起，越来越多传统模具开始转型为新型热流道系统模具，其中热流道的出现，大大提高了许多工厂的生产效率。我们知道，热流道是通过主灌咀1向客户模具3内注入熔融状态的塑胶，如附图1所示。在现有的热流道行业内，普遍都是以法兰2直接固定热流道系统的主灌咀1，其对热流道系统起到定位作用，同时也是整套模具3相对注塑机的定位结构。在注塑机安装模具3时，校正模具3对准注塑机的定位孔，很容易直接撞上模具3上的法兰2，法兰2是直接与主灌咀1本体接触定位，碰撞后容易损伤到主灌咀1，导致主灌咀1螺纹松动，有漏胶风险。主灌咀1的感温元件离发热圈端面较近，法兰2与主灌咀1是直接接触定位，会带走部分热量，造成塑胶从熔融状态注塑进来的时候，喷咀位置剪切热过大，容易造成塑胶分解，进而造成热流道系统加工的产品有发黄、发黑的现象产生。With the popularity of petroleum products (such as plastics, synthetic rubber, etc.), hot runner processing has risen rapidly, and more and more traditional molds have begun to transform into new hot runner system molds. The emergence of hot runners has greatly improved many Factory productivity. We know that the hot runner is to inject molten plastic into the customer's mold 3 through the main nozzle 1, as shown in Figure 1. In the existing hot runner industry, the flange 2 is generally used to directly fix the main nozzle 1 of the hot runner system, which plays a role in positioning the hot runner system, and is also a positioning structure for the entire set of molds 3 relative to the injection molding machine. When installing the mold 3 on the injection molding machine, align the mold 3 with the positioning hole of the injection molding machine, and it is easy to directly hit the flange 2 on the mold 3. The flange 2 is directly in contact with the main filling nozzle 1 for positioning, and it is easy to be damaged after collision. To the main filling nozzle 1, the thread of the main filling nozzle 1 is loosened, and there is a risk of glue leakage. The temperature sensing element of the main nozzle 1 is close to the end face of the heating ring, and the flange 2 and the main nozzle 1 are positioned in direct contact, which will take away part of the heat, causing the nozzle position to shear heat when the plastic is injected from the molten state. If it is too large, it is easy to cause the plastic to decompose, and then cause the products processed by the hot runner system to turn yellow and black.
发明内容Contents of the invention
本发明的目的在于克服上述现有技术中的不足之处，而提供一种热流道隔热式法兰结构。The object of the present invention is to overcome the disadvantages of the above-mentioned prior art, and provide a hot runner heat-insulating flange structure.
本发明是通过如下技术方案实现的：热流道隔热式法兰结构，包括主灌咀及法兰，还包括隔热帽镶件，隔热帽镶件衬垫于法兰内的环槽内，卡簧将隔热帽镶件、主灌咀及法兰固连为一整体。The present invention is realized through the following technical scheme: the heat-insulating flange structure of the hot runner, including the main nozzle and the flange, and also includes the heat-insulating cap insert, and the heat-insulating cap insert is lined in the ring groove in the flange , The retaining spring connects the heat insulating cap insert, the main filling nozzle and the flange as a whole.
所述的隔热帽镶件为塑胶材料。The heat insulating cap insert is made of plastic material.
本发明由于隔热帽镶件为塑胶材料，在安装模具受到碰撞时，会缓解法兰直接作用于主灌咀上的力，起到保护主灌咀的作用，隔热帽镶件避免主灌咀和法兰直接接触，有效减少热传递的损失，减少了主灌咀里面的塑胶的剪切热，使阀针控温更准确。In the present invention, since the heat-insulation cap insert is made of plastic material, when the installation mold is collided, the force directly acting on the main nozzle by the flange will be relieved to protect the main nozzle, and the heat-insulation cap insert can prevent the main The direct contact between the nozzle and the flange can effectively reduce the loss of heat transfer, reduce the shear heat of the plastic inside the main nozzle, and make the temperature control of the valve needle more accurate.

具体实施方式：detailed description:
见附图2～3，热流道隔热式法兰结构，包括主灌咀1及法兰2，还包括隔热帽镶件4，隔热帽镶件4衬垫于法兰2内的环槽内，卡簧5将隔热帽镶件4、主灌咀1及法兰2固连为一整体。See attached drawings 2 to 3, the heat-insulating flange structure of the hot runner, including the main nozzle 1 and the flange 2, and also includes the heat-insulating cap insert 4, the ring of the heat-insulating cap insert 4 lining the flange 2 In the groove, the retaining spring 5 firmly connects the heat insulating cap insert 4, the main filling nozzle 1 and the flange 2 as a whole.
所述的隔热帽镶件4为塑胶材料。The heat insulating cap insert 4 is made of plastic material.
应用本发明时，正常注塑的时候，熔融状态的塑胶通过热流道由主灌咀1注入到模具3内，由于隔热帽镶件4衬垫于法兰2内的环槽内，并且将主灌咀1与法兰2分隔，有效的阻断了由主灌咀1与法兰2之间的热传递，减少了主灌咀里面的塑胶的剪切热，使阀针控温更准确，避免了热流道系统加工的产品发黄、发黑的现象产生。When applying the present invention, during normal injection molding, the plastic in molten state is injected into the mold 3 from the main nozzle 1 through the hot runner, because the heat insulating cap insert 4 is lined in the ring groove in the flange 2, and the main The nozzle 1 is separated from the flange 2, which effectively blocks the heat transfer between the main nozzle 1 and the flange 2, reduces the shear heat of the plastic inside the main nozzle, and makes the temperature control of the valve needle more accurate. It avoids yellowing and blackening of products processed by the hot runner system.
