Description

Technical Field

[0001] The utility model relates to the technical field of mold production, in particular to a spray device for mold demoulding. Background Art

[0002] During the production process of the mold, in order to facilitate the complete removal of the molded product from the mold, a release agent is often sprayed in the mold body. As an interface coating located on the surface of the mold, the release agent can make the surface of the mold in contact with the molding material smooth and clean, reduce the adhesion between the mold and the material, and facilitate the demolding of the molded product.

[0003] However, in the prior art, there is a demoulding spray device with patent number "CN208554682U", which includes: a fixed structure and a spray assembly, a guide groove and a feed port located at the top of the fixed structure and connected to the guide groove are opened in the fixed structure, and the spray assembly includes a plurality of first spray pipes arranged at the bottom of the fixed structure, and the plurality of first spray pipes are arranged along the setting direction of the guide groove, and the first spray pipes are connected to the guide groove. On the one hand, the demoulding spray device can realize mechanized spraying of the demoulding agent on the die-casting, which can effectively improve the work efficiency and save labor costs; on the other hand, a plurality of first spray pipes are arranged at the bottom of the fixed structure, so that the first spray pipes can spray the die-casting in all directions, so that the demoulding agent on the die-casting is sprayed more evenly, which is convenient for removing the die-casting from the external mold through the external ejection device.

[0004] Although the above patent enables the first spray pipe to spray the die-casting in all directions, thereby making the release agent on the die-casting sprayed more evenly, making it easier to remove the die-casting from the external mold through an external ejection device, there are still some shortcomings. For example, the device can only spray the release agent on the mold mechanically. Some molds require manual spraying due to the narrow angle when spraying, which results in the inability of the existing release spray device to spray the release agent on the mold evenly.

If manual operation is required, the spray gun can be directly taken out. The installation is simple and convenient, and the economic cost is not high. The size is small and does not occupy too much space. It can be moved at any time for easy access and operation, and the operation is simple.

[0015] 2. In the utility model, an electric telescopic rod is provided to drive the spray gun to move up and down, so that sufficient release agent can be sprayed on the mold in the longitudinal direction so that the mold can fall off smoothly. By the way, a limit frame and a limit column are provided, which can also improve the stability of the entire device and prevent the fixed table from tilting. BRIEF DESCRIPTION OF THE DRAWINGS

[0024] like Figure 2 As shown, the spray gun 2 is a lower pot type spray gun 2, and the gun body and liquid contact part of the spray gun 2 are made of stainless steel and have a long service life.

[0025] like Figure 1 As shown, an electric telescopic rod 11 is fixedly installed on the top of the fixing seat 12, and the output end of the electric telescopic rod 11 is fixedly connected to the bottom of the fixing platform 1. The electric telescopic rod 11 can be used to adjust the height of the spray gun 2, which is suitable for more scenarios.

[0026] like Figure 4 As shown, two limit frames 13 are fixedly installed on the top of the fixed seat 12, and the inner surface walls of the two limit frames 13 are movably inserted with limit columns 14, and the tops of the two limit columns 14 are fixedly connected to the top of the fixed platform 1, so that the fixed platform 1 can be limited when the electric telescopic rod 11 adjusts the height of the spray gun 2.

[0027] like Figure 1 and Figure 4 As shown, a limit block 15 is fixedly installed on the outer wall of the plug block 9, and a slider 17 is fixedly installed on the outer wall of the clamping block 8. The slider 17 is exposed on the outside of the fixed platform 1, which is more convenient for the staff when they need to open or insert the plug block 9.

[0028] like Figure 1 As shown, a pull ring 16 is fixedly installed on one end of the outer wall of the driving rod 6, so that when the staff needs to pull the driving rod 6 out of the slider 17, they can hold the pull ring 16 and pull it, which improves the convenience of use.
