Injection Mould Daily Maintenance And Maintenance Methods

In today's era of promoting environmental protection and recycling, the maintenance and maintenance of molds is also a top priority. The service life of the mold directly affects the cost of injection moulded products. Therefore, maintaining the quality of injection moulds, maintaining and extending the service life are important issues for injection moulded product processing enterprises to reduce costs and increase efficiency.

The following is a summary of the daily maintenance and maintenance methods of injection moulds for your reference:

1. The injection moulding manufacturer should first equip each pair of molds with a resume card to record and count their use, care (lubrication, cleaning, anti-rust), and damage in detail. Based on this, it can be found which parts and components have been damaged and the degree of wear. Provide information on finding and solving problems, as well as the molding process parameters of the mold and the materials used in the product, so as to shorten the trial run time of the mold and improve production efficiency. the

2. The processing enterprise should test the various properties of the mold under the normal operation of the injection moulding machine and the mold, and measure the size of the final molded plastic part. Through this information, the current state of the mold can be determined, and the cavity and core can be found. According to the information provided by the plastic parts, the damage status of the mold and the maintenance measures can be judged. the

3. At ordinary times, it is necessary to focus on tracking and testing several important parts of the mold: the ejector and guide parts are used to ensure the opening and closing movement of the mold and the ejection of plastic parts. Always keep the mold ejector pin and guide post lubricated (the most suitable lubricant should be selected), and regularly check whether the ejector pin, guide post, etc. are deformed and damaged on the surface. Once found, they should be replaced in time; The working surface, movement, and guide parts of the mold are coated with professional anti-rust oil, and special attention should be paid to the protection of the elastic strength of the mold-bearing parts with gears, racks and spring molds to ensure that they are always in the best working condition; The production time lasts, and the cooling channel is prone to deposit scale, rust, silt, and algae, etc., which makes the cross-section of the cooling channel smaller and the cooling channel narrower, greatly reducing the heat exchange rate between the cooling liquid and the mold, and increasing the production cost of the enterprise. Therefore, convection Attention should be paid to the cleaning of the channel; for hot runner molds, the maintenance of the heating and control system is conducive to preventing production failures, so it is particularly important. Therefore, after the end of each production cycle, the belt heater, rod heater, heating probe, and thermocouple on the mold should be measured with an ohmmeter. Compare and make records so that problems can be discovered in due course and countermeasures can be taken. the

4. Pay attention to the surface maintenance of the mold, which directly affects the surface quality of the product. The focus is to prevent corrosion. Therefore, it is particularly important to choose a suitable, high-quality, professional anti-rust oil. After the mold is produced, different methods should be used to carefully remove the residual injection moulding according to different injection mouldings. Copper rods, copper wires, and professional mold cleaning agents can be used to remove residual injection moulding and other deposits in the mold, and then air dry. It is forbidden to clean with hard objects such as iron wires and steel bars to avoid scratching the surface. If there are rust spots caused by corrosive injection moulding, use a grinder to grind and polish, and spray professional anti-rust oil, and then store the mold in a dry, cool, and dust-free place.
