Description

Technical Field

[0001] The utility model belongs to the technical field of demoulding of injection molded parts, and in particular relates to a demoulding agent spraying mechanism for injection molded parts. Background Art

[0002] Release agent is an auxiliary lubricant used in the injection molding process. The main function of the release agent is to release the product from the mold cavity. After applying the release agent on the high-temperature surface of the mold, a thin film can be formed to protect the mold surface, prevent the product from sticking to the mold, reduce the impact force on the mold during product formation, reduce the wear of the product and the mold, and play a lubricating role; in addition, it can also adjust the temperature of each part of the mold, play a role in maintaining the temperature balance of the mold, improve the formability of the product, thereby increasing the life of the mold and ensuring the quality of the product to a certain extent.

[0003] There are mainly two types of injection molding release agents. One is bulk release agent, which requires the use of a special spraying device. The material pump is used to pump the release agent and spray it on the inside of the mold cavity. The overall expenditure cost is high, and the material pump and nozzle are easy to clog, and the later maintenance is also troublesome. The other is canned release agent, which is mainly a complete pressure packaging container composed of a valve, a container, and contents (including release agent, propellant, etc.). When the nozzle valve on the top is pressed, the release agent can be released at a predetermined pressure in a controlled manner. The overall use cost is low and no maintenance is required. Therefore, the current injection molding machine mostly uses canned release agent when spraying release agent. However, canned release agent needs to be sprayed manually, and the injection molding process is relatively dangerous, resulting in low safety. Therefore, the utility model proposes an injection molded part release agent spraying mechanism, which can automatically press the canned release agent to spray on the mold cavity surface of the injection molding machine mold to ensure the safety of workers at work.
