What are the structures of nylon cable ties?
The emergence of nylon cable ties has brought a lot of convenience to the cable tie industry. How did he do it? This is to start with the composition of the nylon cable ties mold. Below I will give a detailed introduction to the composition of the nylon cable ties mold.
1. Molded parts
A part that imparts a shape, a structure, and a size to a molding material is usually composed of a core (male), a concave mold cavity, a thread core, an insert, and the like.
2, pouring system
It is the passage that directs molten plastic from the nozzle of the injection machine to the closed cavity, usually consisting of a main flow, a split runner, a gate, and a cold well.
3. Guide parts
In order to ensure that the movable part and the guiding part which can be precisely aligned when the fixed mold is closed are guided and positioned, it is composed of a guide post and a guide sleeve, and some molds are also provided with guiding parts on the ejection board to ensure The demolding mechanism moves smoothly and reliably.
4, demoulding mechanism
The device for demoulding the plastic parts and the casting system has many structural forms. The most commonly used demoulding mechanisms such as ejector pins, top tubes, top plates and pneumatic ejections are generally provided by ejector pins, reset bars, slingshots, and ejector pins. The top plate (top ring) and the top plate guide post/guide sleeve are composed.
5, core pulling mechanism
For plastic parts with side holes or undercuts, it is necessary to perform lateral core pulling or splitting the slider (lateral splitting) before being demolded.
6, mold temperature regulation system
In order to meet the mold temperature requirements of the injection molding process, it is necessary to have a mold temperature adjustment system (such as: cooling water, hot water, hot oil, electric heating system, etc.) to adjust the mold temperature.
7, exhaust system
In order to smoothly discharge the gas in the cavity, a venting groove is often formed at the parting surface of the mold, and the gap between the push rods of other molds or other moving parts (such as a slider) can also function as a venting.
8. Other structural parts Refer to parts that are set to meet the requirements of the mold structure (such as: fixed plate, moving / fixed template, struts, support plates and connecting screws, etc.).
