Description

Technical Field

[0001] The invention relates to the technical field of mold and jig cleaning, and in particular to a mold and jig cleaning method for curing resin. Background Art

[0002] Epoxy resin is widely used in the production of composite materials and electronic packaging devices. After the epoxy resin is cured at high temperature and the product is taken out, epoxy resin will remain on the surface of the mold. In order to ensure product quality, the residual material on the surface of the mold needs to be cleaned up. Currently, it relies on manual physical methods to clean one by one, which is extremely inefficient and easy to damage the mold due to operational errors, making it difficult to meet large-scale production needs. Summary of the invention

[0003] In view of the above problems, the present invention provides a method for cleaning a mold and jig for curing resin, which improves the cleaning efficiency, reduces the wear of the mold and jig, extends the service life, and meets the needs of large-scale production.

[0004] A method for cleaning a mold and jig for curing resin is characterized in that the mold and jig to be cleaned is immersed below the liquid level of a cleaning agent in a cleaning tank of an ultrasonic cleaning machine, and residual resin on the surface of the mold and jig is removed by ultrasonic cleaning.

[0005] It is further characterized by:

[0006] The cleaning agent uses a mixture of sodium bicarbonate and sodium carbonate as a cleaning solvent, which significantly improves the cleaning efficiency and effectively decomposes the swelling resin stains;

[0007] The cleaning agent is also combined with ethylene glycol butyl ether as a penetrant to ensure that the efficiency of ultrasonic cleaning is improved;

[0008] The cleaning solution comprises a cleaning agent, a penetrant and water;

[0009] The weight formula of the cleaning solution is: 18%±2% sodium bicarbonate, 30%±3% calcium carbonate, 6%±2% ethylene glycol butyl ether, and the rest is water;

[0010] During ultrasonic cleaning, the temperature of the cleaning solution is 30°C to 40°C, which ensures high cleaning efficiency;

[0011] During ultrasonic cleaning, after the set basic time, manually observe whether the mold cavity has been cleaned. After cleaning, shut down the machine in time, take out the mold, and put in the mold to be cleaned;

[0012] During the ultrasonic cleaning of the mold and jig, the mold and jig must be completely immersed in the liquid surface of the cleaning solution, and the mold and jig must not be stacked, and the surface of the mold and jig that needs to be cleaned must be in contact with the clear and dilute solution as a whole;

[0013] If there is no obvious sign of cleaning on the mold and fixture surface within the set basic time, it is determined that the cleaning solution has reached saturation, and the cleaning solution is replaced as a whole, and the cured resin on the mold and fixture surface is ultrasonically cleaned again;

[0014] It can handle the cleaning of cured resin of molds and jigs of different shapes and sizes.

[0015] After adopting the present invention, this cleaning method can accurately and efficiently remove the resin residue stains on the surface of metal molds and fixtures, and occupies an important position in the field of mold cleaning technology. Compared with traditional pure manual cleaning, it ensures cleaning efficiency while preventing damage to molds and fixtures. Its powerful large-scale cleaning ability injects strong impetus into the production and processing flow in the field of composite materials, accelerating the improvement and development of industry production efficiency. DETAILED DESCRIPTION

[0016] A method for cleaning a mold and jig for curing resin: immersing the mold and jig to be cleaned below the cleaning agent liquid level in a cleaning tank of an ultrasonic cleaning machine, and removing residual resin on the surface of the mold and jig by ultrasonic cleaning.

[0017] It includes the following steps:

[0018] S1. Prepare a cleaning solution: The weight formula of the cleaning solution is 18%±2% sodium bicarbonate, 30%±3% calcium carbonate, 6%±2% ethylene glycol butyl ether, and the rest is water;

[0019] S2. Select an ultrasonic cleaning machine of appropriate size according to the shape and size of the mold and fixture, so that the cleaning tank of the ultrasonic cleaning machine can completely immerse the largest mold and fixture;

[0020] S3, pouring the pre-configured clear and diluted solution into the ultrasonic cleaning tank;

[0021] S4, heating the cleaning solution in the ultrasonic cleaning tank to 30°C to 40°C by a heating device, and ensuring that the temperature of the cleaning solution is always maintained at 30°C to 40°C by a heat preservation device;

[0022] S5. The mold and jig to be cleaned is transferred to the bottom of the cleaning tank by the transfer equipment, and is slowly lowered so that the mold and jig to be cleaned is completely immersed below the liquid surface of the cleaning solution in the cleaning tank, and it is ensured that the mold and jig is completely immersed below the liquid surface of the cleaning solution, and the mold and jig is not stacked, and the surface of the mold and jig to be cleaned is in contact with the clean solution as a whole;

[0023] S6, the ultrasonic cleaning machine starts ultrasonic cleaning. After the set basic time, the mold cavity of the mold is manually observed to see if it has been cleaned. After cleaning, the machine is turned off in time, the mold is taken out, and the mold to be cleaned is put in;

[0024] When there is no obvious sign of cleaning on the surface of the mold and fixture within the set basic time, it is determined that the cleaning solution has reached saturation, and the cleaning solution is replaced as a whole, and the cured resin on the surface of the mold and fixture is ultrasonically cleaned again.

[0025] In step S1, the preferred formula of the cleaning solution is 18% sodium bicarbonate, 30% calcium carbonate, 6% ethylene glycol butyl ether, and the rest is water.

[0026] The beneficial effects are as follows: the combination of sodium bicarbonate and sodium carbonate as a cleaning solvent can significantly improve the cleaning efficiency and effectively decompose and swell resin stains; the use of ultrasonic cleaning machines can realize batch processing of molds and jigs, greatly improving the cleaning efficiency, and reducing the wear of molds and jigs, extending their service life; this method has a wide range of applicability and can cope with molds and jigs of different shapes and sizes. Within the applicable range of ultrasonic cleaning agents, it can reduce labor and material costs for related companies, effectively promote the improvement of production efficiency, and has extremely broad market application prospects.
