技术领域technical field
本发明涉及一种注射模具，特别是涉及一种注射模具的顶出机构。The invention relates to an injection mold, in particular to an ejection mechanism of the injection mold.
背景技术Background technique
零件在注射完成后顶出时，现有的顶出机构将料道和零件一起顶出，由于普遍采用切浇口，料道和零件顶出后分离，顶出过程中料道可能会弹飞零件或料道弹伤零件外观，因此需要将料道和零件分别按照次序顶出。When the part is ejected after the injection is completed, the existing ejection mechanism ejects the material channel and the part together. Since the gate is generally used, the material channel and the part are separated after ejection, and the material channel may bounce off during the ejection process. The appearance of the part or the feeder is damaged by bullets, so the feeder and the parts need to be ejected in order.
发明内容Contents of the invention
本发明要解决的技术问题：针对料道和零件同时顶出存在的上述问题，提供了一种将料道和零件依次顶出的机构。The technical problem to be solved by the present invention is to provide a mechanism for sequentially ejecting the material channel and parts in view of the above-mentioned problems of simultaneous ejection of the material channel and parts.
本发明技术方案：Technical scheme of the present invention:

A through hole is opened in the middle of the backing plate of the ejector rod and the bottom plate, and the connecting rod of the machine tool is installed in the hole. The upper half is divided into two halves, and there is a time-delay ejector insert in the groove, and the lower end of the ejector rod of the feedway is pressed on the delay ejector insert.
槽的深度大于顶杆垫板的厚度，延时顶料镶件的宽度大于机床连接杆的直径。The depth of the groove is greater than the thickness of the backing plate of the ejector rod, and the width of the delay ejector insert is greater than the diameter of the connecting rod of the machine tool.
本发明的有益效果：Beneficial effects of the present invention:
通过本机构，可以将料道和零件按照顺序顶出，先顶出零件，再顶出料道，防止料道在顶出过程中弹飞零件或者弹伤零件。Through this mechanism, the material channel and parts can be ejected in sequence, the parts are ejected first, and then the material channel is ejected, so as to prevent the material channel from flying or damaging the parts during the ejection process.

具体实施方式：detailed description:
实施例：如图，零件顶杆5安装在顶杆固定板1上，顶杆固定板1下方依次是顶杆垫板3和底板6，顶杆垫板3和底板6中部开设有通孔，用于安装机床连接杆5，机床连接杆5穿过顶杆垫板3和底板6顶在顶杆固定板1下方。机床连接杆5上开设有一道槽，该槽将机床连接杆5的上半段分成左右两半，槽中有一块矩形的延时顶料镶件4，料道顶杆2的下端穿过顶杆垫板3压在延时顶料镶件4上。槽的深度比顶杆垫板3的厚度超出5-7mm（视为顶出零件距离而定），延时顶料镶件4的宽度比机床连接杆5的直径大10%左右，在合模状态下延时顶料镶件4相对机床连接杆5上设有的槽是悬空状态，顶料镶件4两端压在底板6上。零件顶出时，机床连接杆5推动顶杆垫板3向上运动，同时零件顶杆5向上运动开始顶出料道，而由于延时顶料镶件4此时是悬空在槽中，机床连接杆5此时不能推动延时顶料镶件4运动，从而料道顶杆2也不动，直到槽的底部顶到延时顶料镶件4后才开始将料道顶出。Embodiment: As shown in the figure, the ejector rod 5 of the part is installed on the ejector rod fixing plate 1. Below the ejector rod fixing plate 1 are the ejector rod backing plate 3 and the bottom plate 6 in sequence. A through hole is opened in the middle of the ejector rod backing plate 3 and the bottom plate 6. It is used to install the connecting rod 5 of the machine tool. The connecting rod 5 of the machine tool passes through the backing plate 3 and the bottom plate 6 of the ejector rod and pushes under the fixing plate 1 of the ejector rod. There is a groove on the connecting rod 5 of the machine tool, which divides the upper half of the connecting rod 5 into two halves. There is a rectangular time-delay ejector insert 4 in the groove, and the lower end of the feeder ejector rod 2 passes through the ejector The rod backing plate 3 is pressed on the delay top material insert 4. The depth of the groove is 5-7mm higher than the thickness of the ejector rod backing plate 3 (determined as the distance of the ejected part), and the width of the delay ejector insert 4 is about 10% larger than the diameter of the machine connecting rod 5. Under the state, the groove that the time-delay ejector insert 4 is provided with relative to the machine tool connecting rod 5 is in a suspended state, and the two ends of the ejector insert 4 are pressed on the base plate 6 . When the part is ejected, the machine tool connecting rod 5 pushes the ejector rod backing plate 3 to move upward, and at the same time, the part ejector rod 5 moves upward to start ejecting the material path, and because of the delay, the ejector insert 4 is suspended in the groove at this time, and the machine tool connection Bar 5 can't push delay ejector insert 4 to move at this moment, thereby forehearth push rod 2 also does not move, and just begins to forehearth ejection after the bottom of groove pushes delay ejector insert 4.
