Problems solved by technology

In the existing production, the aspheric surface of the mold core is sensitive and fragile by manual wiping one by one. If the wiping method is improper, the aspheric surface will become more and more dirty, and even scratches will appear on the aspheric surface, resulting in scrapping or return to factory for repair
In addition, it takes a long time to wipe the mold core, and the wiping efficiency is low

Embodiment

[0027] The invention provides a special mold core cleaning and maintenance method for optical lens molds, which specifically includes the following steps:

[0028] Step 1: Preparation before operation: Prepare relevant tools and supplies, including hexagonal wrench, adjustable wrench, afterburner rod, red copper rod, environmental protection optical mold cleaning agent, ultrasonic wave, alcohol or ether, oil stone, desk lamp, microscope, clean rag , absorbent cotton, cotton swabs, and pliers, but not limited to.

[0029] Specifically, when the mold needs to be maintained, the mold maintenance schedule is first proposed according to the molding process, and the mold room will maintain the mold according to the requirements, and except for the inner hexagonal wrench, adjustable wrench, afterburner, red Copper rods, environmentally friendly optical mold cleaners, ultrasonic waves, alcohol or ether, oil stones, desk lamps, microscopes, clean rags, absorbent cotton, cotton swabs, p...

Abstract

The invention discloses a special mold core cleaning and maintaining method for an optical lens mold, and particularly relates to the technical field of mold core cleaning and maintaining. The methodspecifically comprises the following operation steps: preparing related tools and articles before operation, performing parting, removing a mold core, cleaning the mold, maintaining the mold core, assembling the mold core, assembling all parts of the mold in sequence, confirming actions, closing the mold, and making a mold maintenance schedule table for learning and popularizing. According to themethod, screws for fixing side mold plates are unscrewed but not disassembled, then the mold core and the mold plates are respectively disassembled and cleaned with ultrasonic waves and an environment-friendly optical mold cleaning agent with the aid of alcohol or diethyl ether, meanwhile, the surface of the mold core is further wiped clean by medical degreasing cotton dipped with alcohol or methylbenzene / acetone, and then dirt on other parts of the mold core is thoroughly removed, so that the mold and mold core cleaning mode is changed, the efficiency is improved, the quality is improved, andthe method is suitable for application and popularization.

Description

technical field [0001] The invention relates to the technical field of mold core cleaning and maintenance, and more specifically, the invention relates to a special mold core cleaning and maintenance method for optical lens molds. Background technique [0002] The mold core refers to the precision parts used for the critical operation of the central part of the mold. Mold cores are generally extremely complex in structure, difficult to process, and expensive to manufacture. Often, the labor cost of manufacturing greatly exceeds the material itself. Optical mold cores are used to cast aspheric plastic lenses. [0003] The mold core in the mold for forming optical plastic lenses, in the process of continuous injection molding of plastic lenses, due to the impact of gas or sudden gas failure, power failure, machine failure, etc., indirectly causes scratches, pitting, etc. on the aspheric surface in the mold core. Dirt, etc., resulting in poor appearance of the lens, which make...
