注塑模具的结构组成有哪些?

1、成型零件
1. Molding Parts
赋予成型资料外形、构造、尺寸的零件,通常由型芯(凸模)、凹模型腔以及螺纹型芯、镶块等构成。
Parts endowed with shape, structure and size of forming materials are usually composed of core (punch), concave cavity, threaded core, insert, etc.
2、浇注系统
2. Gating system
它是将熔融塑料由注射机喷嘴引向闭合模腔的通道,通常由主流道、分流道、浇口和冷料井组成。
It is a passage leading molten plastic from injector nozzle to closed die cavity. It is usually composed of main flow passage, shunt passage, gate and cold material well.
3、导向部件
3. Guide Parts
为了保证动模与定模闭合时可以准确对准而设置的导向部件,起导向定位作用,它是由导柱和导套组成的,有的模具还在顶出板上设置了导向部件,保证脱模机构运动平稳牢靠。
In order to ensure the precise alignment of the guide parts when the moving die and the fixed die are closed, the guide parts are composed of the guide pillar and the guide sleeve, and some of the dies are also equipped with the guide parts on the ejector plate to ensure the smooth and reliable movement of the demoulding mechanism.
4、脱模机构
4. Demoulding mechanism
完成塑件和浇注系统脱模的安装,其构造方式很多,常用的有顶杆、顶管、顶板及气动顶出等脱模机构,普通由顶杆、复位杆、弹弓、顶杆固定板、顶板(顶环)及顶板导柱/导套等组成。
There are many ways to complete the demoulding installation of plastic parts and pouring system. The most commonly used demoulding mechanisms are ejector rod, pipe jacking, roof and pneumatic ejector. They are usually composed of ejector rod, reset rod, slingshot, ejector fixing plate, roof (top ring) and roof guide pillar/guide sleeve.

5、抽芯机构
5. Core-pulling mechanism
关于有侧孔或侧凹的塑件,在被顶出脱模之前,必需先停止侧向抽芯或分开滑块(侧向分型),方能顺利脱模。
For plastic parts with side holes or concave side holes, it is necessary to stop side core pulling or separate sliders (lateral parting) before ejection and demoulding.
6、模温调理系统
6. Mould Temperature Conditioning System
为了满足注射成型工艺对模具温度的请求,需求有模温调理系统(如:冷却水、热水、热油及电热系统等)对模具温度停止调理的安装。
In order to meet the requirement of injection moulding process for mould temperature, the installation of mould temperature conditioning system (such as cooling water, hot water, hot oil and electrothermal system) is required.
7、排气系统
7. Exhaust system
为了将模腔内的气体顺利排出,常在模具分型面处开设排气槽,许多模具的推杆或其它活动部件(如:滑块)之间的间隙也可起到排气作用。
In order to discharge the gas in the die cavity smoothly, an exhaust groove is often set up at the parting surface of the die. The clearance between push rods or other movable parts (e.g. sliders) of many dies can also play an exhaust role.
8、其它构造零件
8. Other structural parts
满足模具构造上的请求而设置的零件(如:固定板、动/定模板、撑头、支承板及衔接螺钉等)。
Parts set up to meet the requirements of die construction (e.g. fixed plate, movable/fixed template, brace, supporting plate and connecting screw, etc.).
