[0026] The demolding assembly 200 includes a push plate 201 installed inside two mounting seats 103, a mold base 202 is installed inside the push plate 201, a push plate insert ring 203 is sleeved on the side surface of the mold base 202, a positioning sleeve 204 is installed inside the mold base 202, an insert 205 is installed on the upper end of the positioning sleeve 204, a plurality of second air holes 206 are opened on the side surface of the insert 205, a positioning ring 207 is sleeved on the side surface of the push plate insert ring 203, and the positioning ring 207 is clamped in the push plate 201, a center top 208 is inserted into the mold base 202, two air paths 209 are opened in the center top 208, two cylinders 210 are installed inside the base 101, and the output ends of the two cylinders 210 are connected to the center top 208, a vent hole 220 is opened on one side of the push plate 201, and a workpiece body 230 is sleeved on the upper end of the mold base 202.

[0027] In a specific embodiment, the stabilizing component 100 cooperates with the demolding component 200 to not only perform gas-assisted lifting operation through a single lifting plate 106, but also improve the demolding stability. At the same time, the above structures cooperate with each other to improve the overall stability of the demolding structure, thereby enhancing the safety of use of the demolding structure. When performing the demolding operation, firstly, the edge vacuum between the workpiece body 230 and the mold base 202 is broken by adding gas through the push plate insert ring 203, so that the clamping force of the lower end edge of the workpiece body 230 is eliminated in advance.

[0035] In a specific embodiment, the positioning shaft 211 has a positioning effect on the push plate 201 , and the connection between the connecting head 212 and the center top 208 can improve the connection stability between the cylinder 210 and the center top 208 .

[0036] See also Figure 4 - Figure 6 A stabilizing frame 221 is installed inside the positioning sleeve 204 .

[0037] In a specific embodiment, the stabilizing frame 221 is used to support and position the insert 205 to prevent the workpiece body 230 from deviating and affecting the production quality.

[0040] Working principle: When performing the demoulding operation, firstly, the vacuum at the edge between the workpiece body 230 and the mold base 202 is broken by adding air through the push plate insert ring 203, so that the clamping force at the lower end edge of the workpiece body 230 is eliminated in advance, and at the same time, the second air hole 206 arranged at the insert 205 can eliminate the side wall and bottom of the entire workpiece body 230 and the clamping force of the mold base 202, and then the mold lifting plate 106 is lifted by the injection molding machine, and the force in the mold opening direction is transmitted by the ejector rod and the center top 208 and the cylinder 210 are ejected synchronously, and at the same time, the gas passing through the gas path 209 can further lift the workpiece body 230 so that the workpiece body 230 can be separated from the mold base 202 as a whole, and finally, after the lifting plate 106 is in place, the cylinder 210 is controlled to pressurize, and the undercut at the edge of the workpiece body 230 is separated from the push plate 201 through the center top 208, so that the demoulding operation of the entire workpiece body 230 can be realized, and the practicality of the demoulding structure is enhanced.
