Description
Technical Field
[0001] The utility model relates to the technical field of injection molds, in particular to an injection mold which is convenient to clean. Background Art
[0002] With the rapid development of the plastics industry, injection molds have been widely used in many fields such as automotive parts, home appliances, daily necessities, medical devices, industrial parts, etc. However, during the use of injection molds, there is usually a small amount of injection material and oil residue in the mold cavity. As these residues continue to accumulate, the surface finish of the mold will often decrease, which will affect the appearance quality and dimensional accuracy of the injection molded product. In addition, the dirt inside the mold may also affect the fluidity and cooling effect of the plastic material, increase the defective rate, and even damage the mold itself, shortening its service life.
[0003] When some existing injection molds are in use, the cleaning mechanisms added thereto need to rely on manual brushing of the inside of the mold, which is time-consuming and labor-intensive to clean, and manual brushing may also cause damage to the mold.
[0004] For example, an injection mold that is easy to clean is disclosed with announcement number CN211440928U. When the injection mold of this patent is used, when it is necessary to clean the lower mold, it is only necessary to use an external water pipe to inject water into the lower mold through a nozzle, and then brush it. After brushing, pull the clamping rod to the left through the operating panel to disengage it from the slot. At the same time, the lower mold is turned by turning the handle to rotate it around the first bearing and the second bearing. When the lower mold rotates one hundred and eighty degrees, all impurities in the lower mold can be discharged. After dumping is completed, it is only necessary to turn the handle to turn the lower mold back to its original position, and under the elastic force of the connecting spring, the clamping rod is clamped in the slot to fix the lower mold, thereby not affecting the normal use of the mold.
[0005] Although the injection mold has made some improvements in terms of cleaning convenience, there are still many links that require manual operation. Although a nozzle is designed to inject water into the mold, the cleaning process still requires the staff to manually use brushes and other tools to brush the inside of the mold to remove stubborn impurities and residues. This manual brushing not only increases the labor intensity of the staff. Although the mold is designed with a flipping mechanism, the flipping process requires the staff to manually operate the handle to achieve it. This not only requires the staff to have a certain amount of physical strength and skills, but may also cause the mold to flip unsteadily or be damaged due to improper operation. In addition, manual flipping of the mold also increases the operation time and reduces work efficiency.
[0006] Therefore, it is necessary to invent an injection mold that is convenient to clean to solve the above problems. Utility Model Content

[0035] The working principle of the utility model:
[0036] Refer to the attached Figures 1-5 description. When using the utility model, first inject an appropriate amount of clean water into the electric heating water tank 6 through the water injection pipe 13. Subsequently, start the heating function of the electric heating water tank 6 to heat the clean water until the water temperature reaches a suitable temperature for cleaning.
[0037] After the injection process is completed, use the electric push rod 3 to slowly lift the injection upper mold 4 upward to ensure that the injection upper mold 4 is completely separated from the injection lower mold 5. Then take out the injection part inside the injection lower mold 5. During the injection process, a small amount of raw materials and oil stains will remain in the cavity of the injection lower mold 5, which need to be cleaned in time to avoid adverse effects on subsequent injection operations.
[0038] Start the first water pump 7 to pump the hot water inside the electric heating water tank 6. The operator holds the high-pressure flushing gun 10 and comprehensively flushes the inside of the injection lower mold 5. Utilize the impact of the high-pressure water flow and the softening of the dirt by the hot water to quickly peel off the dirt on the mold surface.
[0039] After the flushing is completed, place the high-pressure flushing gun 10 back on the lifting bracket 12. Then, the operator holds the waste water suction head 11 and probes it into the mold. Start the second water pump 9 to suck the waste water inside the mold through the pipeline into the waste water tank 8 until there is basically no accumulated water inside the mold. After the waste water tank 8 is full, the waste water can be discharged through the drain pipe 14 for subsequent treatment.
[0040] Start two linear modules 18. Drive the suspension bracket 17 and the air guide cover 16 to move through their sliders until the air guide cover 16 moves directly above the injection mold lower die 5. Start the hot air blower 15.
