Embodiment 2

[0023] Step 1: Prepare the raw materials of the liquid mold cleaning agent according to the above method, wherein, in terms of parts by mass, first add 15 parts of cleaning agent and put it into the stirring tank, then add 3 parts of surfactant, then add 70 parts of solvent, and start stirring Kettle, stirred for 30 minutes, mixed evenly and put into a watering can with a nozzle for spraying.

[0024] Step 2: Spray the liquid mold cleaning agent used for cleaning the plastic sealing mold on the surface of the injection mold, then place the rubber strip on the injection mold, close the mold and pressurize, heat to 160-190°C, keep curing for 5 minutes, and then Open the mold, take off the rubber strip, the dirt on the injection mold is stuck on the rubber strip, and the injection mold is cleaned. This formula is a unique formula system used in the present invention and used in conjunction with rubber mold clearing glue. The raw materials include ethanolamine, n-butyl ether, diet...

Embodiment 3

[0026] Step 1: Prepare the raw materials of the liquid mold cleaning agent according to the above method, wherein, in terms of parts by mass, first add 20 parts of cleaning agent and put it into the stirring tank, then add 5 parts of surfactant, then add 80 parts of solvent, and start stirring Kettle, stirred for 30 minutes, mixed evenly and put into a watering can with a nozzle for spraying.

[0027] Step 2: Finally, spray the liquid mold cleaning agent used for cleaning the plastic sealing mold on the surface of the injection mold, then place the adhesive strip on the injection mold, close the mold and pressurize, heat to 160-190°C, and keep curing for 5 minutes. Then open the mold, take off the rubber strip, the dirt on the injection mold is stuck on the rubber strip, and the injection mold is cleaned up.

Abstract

The invention discloses a liquid mold cleaning agent for cleaning a plastic package mold, which is used for solving the problems that the traditional mold cleaning method is particularly time-consuming, the labor intensity is high in the mold dismounting process, and a precision mold is easy to damage. The problems that melamine toxic substances exist in mold cleaning glue, the mold cleaning frequency is high, and the occupied production time is long are solved. The liquid mold cleaning agent for cleaning the plastic package mold is prepared from the following components in parts by mass: 10-20 parts of a cleaning agent, 1-5 parts of a surfactant and 60-80 parts of a solvent. The cleaning agent is put into a stirring kettle, the surfactant is added, the solvent is then added, the stirringkettle is started, stirring is conducted for 30 minutes, and after uniformly mixed, the cleaning agent is sprayed on an injection mold for use. The liquid mold cleaning agent for cleaning the plasticpackage mold and the mold cleaning adhesive tape have a synergistic matching effect, so that the mold cleaning capacity can be enhanced, the mold cleaning frequency is reduced, the mold cleaning timeis saved, and the production efficiency is improved.

Description

technical field [0001] The invention relates to the field of cleaning agents, in particular to a mold cleaning agent for plastic sealing molds. Background technique [0002] Injection molding is a method of producing shapes for industrial products. Products usually use rubber injection molding and plastic injection molding. Injection molding can also be divided into injection molding molding method and die casting method. Injection molding machine (referred to as injection machine or injection molding machine) is the main molding equipment for making thermoplastic or thermosetting materials into various shapes of plastic products using plastic molding molds. Injection molding is realized through injection molding machines and molds. Injection mold is a tool for producing plastic products, and it is also a tool for giving plastic products complete structure and precise dimensions. [0003] During the production of injection molds, some plastic sealing compound will inevita...
