Working principle of mould of injection pipe:
1, plastic mold is the plastic processing industry and plastic molding machine supporting, to give the plastic products with a complete configuration and precise size of tools. Due to the variety of plastics and processing methods, the structure of plastic molding machines and plastic products is not the same, so the types and structures of plastic molds are also diverse.
2, according to the different molding methods, it can be divided into plastic mold types corresponding to different process requirements, mainly injection molding molds, extrusion molds, suction molds, high-foam polystyrene molds and so on.
Standards for injection moulds:
In order to improve the quality grade of the mold, reduce the number of complaints about the quality of the mold, hand over the mold to the customer's satisfaction, summarize and summarize the common problems of the mold manufacturing, and establish standards and implement them as required. 1. Modules less than 2020, a and B plates need to be made between the mold pits; Modular embryo templates greater than 2020, including thimble plates, are to be primed.
2, mold embryo guide column guide sleeve to process exhaust tank, in order to prevent the guide column guide sleeve strain. There must be no sharp corners on the mold and it needs to be handled upside down. Except where specified. .. No internal mould and die parts shall be soldered without consent. The outer surface of the die product must be opened in the appropriate position, please refer to the mold design manual.
3, as far as possible to avoid the use of grinding machines to polish the mold, if it is necessary to use the grinder to process, must use the oil to save light(is the sub-surface) internal mold rubber surface surface surface treatment must be in accordance with the Bomtable, or other formal notification technical requirements. Processing lines on non-rubber surfaces(wire cutting, milling machines, CNC gongs, Spark machines) also need to be sparklers. The inner mould material and mould embryo grade requirements must be purchased according to the order or the technical requirements formally confirmed during the design review process. Material proof must be provided, and in the case of hard molds, heat treatment reports must be provided. Relevant proof. The front and rear die of the mold, inlay, line position, oblique top, straight top(push block), shovel chicken, etc. need to process a waist round pit on the bottom or side to engrave the material name and hardness.
How to maintain mould of injection pipe:
1, daily maintenance of plastic pipe parts mold: All kinds of sports parts such as thimble, line position, guide post, guide sleeve refueling, cleaning of the mold surface, water transport channel, this is the mold production every day to maintain.
2, plastic pipe mold regular maintenance: regular maintenance, including daily maintenance, but also exhaust tank cleaning, gas burning black plus exhaust, damage, wear site correction and so on.
3, plastic tube mold appearance maintenance: paint on the outside of the mold, so as not to rust, when die, fixed die should be coated with rust-resistant oil, mold preservation should be closed tightly, to prevent dust into the cavity.
4, to pay attention to the surface maintenance of the mold, it directly affects the surface quality of the product, the focus is to prevent Rust, so, choose a suitable, professional anti-rust oil is particularly important. When the mould completes the production task, the residual injection molding should be carefully removed by different methods according to different injection molding. The residual injection molding and other sediments in the mold can be removed with copper rods, copper wire and professional mold cleaning agents, and then dried. It is forbidden to clean hard objects such as wire and steel bars so as not to scratch the surface. If there are corrosive rust points caused by injection molding, use a grinder to grind and polish, and spray professional rust resistant oil, and then store the mold in a dry, cool, dust-free place.
Through the above introduction, I believe that everyone has a certain understanding of the principle of injection pipe mold, in addition, injection pipe mold production, must strictly follow the above mentioned, in addition, injection pipe mold should also pay attention to maintenance, Only reasonable maintenance, can the longer use of injection pipe die, so, save money and save money.
