Description

Technical Field

[0001] The invention relates to the technical field of spraying equipment, in particular to a release agent spraying equipment. Background Art

[0002] The surface of the mold is usually covered by a very thin or even monomolecular water film. This extremely thin water film reacts with isocyanate to produce strong adhesion. In order to make the product demould well, the mold surface must have a dense and smooth film. The film is required to not react with the raw materials and have a certain adhesion to the mold, and at the same time have a certain flexibility. The effective demoulding material is evenly sprayed on the mold through the medium, and a smooth film is formed after the medium evaporates, thereby achieving a demoulding effect. Traditional mold release agent spraying is all done by manual spraying, which has low spraying efficiency and poor spraying coverage, thus affecting the subsequent demoulding process.

[0003] Those skilled in the art have conducted research on this. For example, in the technical solution of the intelligent release agent sprayer with application number CN202220799671.9, a driving motor is used to realize a rotary spraying of the nozzle, so that the sprayed release agent is better distributed on the side wall of the mold cavity through centrifugal action, which facilitates the subsequent demolding work of the staff. However, the device still has many defects. It is difficult for the device to effectively fix the mold, and the stability during operation is poor. In addition, the release agent is delivered by multiple nozzles, which is easy to splash out and cause waste of resources and affect the working environment. To this end, we propose a release agent spraying equipment. Summary of the invention
