[0018] See also Figures 1 to 3 In a specific embodiment, a device for automatically spraying a mold release agent for rubber and plastic foaming is provided, comprising a support tube 8, a plurality of cantilevers 5 are arranged at intervals on the side of the support tube 8, a receiving groove 6 is arranged inside one end of the cantilever 5 away from the support tube 8, a swing arm 4 is rotatably arranged in the receiving groove 6, a spray rod 2 is arranged on the swing arm 4, a plurality of nozzles 1 are arranged on the spray rod 2, the spray rod 2 is accommodated in the receiving groove 6, and a connecting rod 7 is hinged on the outer wall of the swing arm 4 for swinging the spray rod 2 and the cantilever 5 open at a ninety-degree angle.

[0019] Specifically, the support tube 8 and the cantilever 5 both play a supporting role. In the initial state, the spray rod 2 and the nozzle 1 are accommodated in the receiving groove 6. When the cantilever 5 enters the mold cavity of the hydraulic press and needs to spray the demoulding agent to help the material to be demoulded, the cylinder 9 is driven, and the connecting piece 10 drives the connecting rod 7 to move linearly, and the swing arm 4 drives the spray rod 2 to open to the outside of the receiving groove 6, so that the spray rod 2 and the cantilever 5 are swung open at a ninety-degree angle. The delivery pump 11 is used to pressurize and deliver the demoulding agent, and spray the demoulding agent from the position of the nozzle 1. After the demoulding agent spraying operation is completed, the cylinder 9 is driven, and the connecting piece 10 drives the connecting rod 7 to move linearly, and the swing arm 4 drives the spray rod 2 to be accommodated in the receiving groove 6. When the cantilever 5 is away from the mold cavity of the hydraulic press, the spray rod 2 and the nozzle 1 are prevented from touching the material to cause adverse effects.

[0020] like Figure 1 As shown, as a preferred embodiment of the above embodiment, one end of the connecting rod 7 is connected to the connecting piece 10, the connecting piece 10 is connected to the telescopic shaft end of the cylinder 9, and the cylinder 9 is arranged on the side of the support tube 8.

[0021] Specifically, by driving the air cylinder 9, the swing arm 4 can drive the spray rod 2 to swing open from the receiving groove 6. In addition, the air cylinder 9 can also be equivalently replaced by an electric push rod or an oil cylinder.

[0022] like Figure 1 As shown, as a preferred embodiment of the above embodiment, the spray rod 2 is connected to the delivery hose 3, and the delivery hose 3 is extended to connect the delivery pump 11.

[0025] Specifically, the connecting rod 7 passes through the inside of the supporting tube 8 and the cantilever 5, so that the connecting rod 7 is not arranged outside, and the external environment is prevented from affecting the transmission function of the connecting rod 7, thereby improving the overall practicality of the device.

[0026] like Figure 1 As shown, as a preferred embodiment of the above embodiment, the output port of the nozzle 1 faces away from the cantilever 5.

[0027] Specifically, the output port of the nozzle 1 is located in the mold cavity of the hydraulic press.

[0028] The specific working principle of the utility model is as follows: the support tube 8 and the cantilever 5 both play a supporting role. In the initial state, the spray rod 2 and the nozzle 1 are accommodated in the receiving groove 6. When the cantilever 5 enters the mold cavity of the hydraulic press and needs to spray the demoulding agent to help the material to be demoulded, the cylinder 9 is driven, and the connecting piece 10 drives the connecting rod 7 to make a linear motion, and the swing arm 4 drives the spray rod 2 to open toward the outside of the receiving groove 6, so that the spray rod 2 and the cantilever 5 are swung open at a ninety-degree angle. The delivery pump 11 is used to pressurize and deliver the demoulding agent, and spray the demoulding agent from the position of the nozzle 1. After the operation of spraying the demoulding agent is completed, the cylinder 9 is driven, and the connecting piece 10 drives the connecting rod 7 to make a linear motion, and the swing arm 4 drives the spray rod 2 to be accommodated in the receiving groove 6. When the cantilever 5 is away from the mold cavity of the hydraulic press, the spray rod 2 and the nozzle 1 are prevented from touching the material to cause adverse effects.
