[0007] As a preferred technical solution of the utility model, the top end of the push rod passes through the inside of the through hole, and the combined pressure rod corresponds to the positioning socket one by one.

[0008] As a preferred technical solution of the utility model, the guide pillars are parallel to each other, and the upper mold base can be lifted and moved outside the guide pillars.

[0009] As a preferred technical solution of the utility model, the lubrication assembly includes a lubrication oil groove, which is arranged at the four corners of the bottom end of the upper mold base outside the guide column. A lubrication pad is embedded in the bottom end of the lubrication oil groove, and an oil filling port is arranged on one side of the lubrication oil groove.

[0010] As a preferred technical solution of the utility model, the lubricating oil groove and the lubricating pad are annular, and the inner side of the lubricating pad fits with the outer side of the guide column.

[0011] Compared with the prior art, the utility model can achieve the following beneficial effects:

[0012] 1. By arranging an ejector assembly inside the fixed mold, when the mold is used to produce the air outlet blades, the movable mold descends and closes with the fixed mold, and at the same time, the combined pressure rod is inserted into the inside of the positioning socket and presses down the lifting plate to make the ejector rod descend and retract to the inside of the perforation. When the air outlet blades are injection molded in the mold and the mold is separated after cooling, the movable mold rises and drives the combined pressure rod to rise. At the same time, the lifting plate is pushed by the reset spring to drive the ejector rod to rise and reset, so that the air outlet blades can be ejected from the mold cavity, thereby facilitating the workers to collect the air outlet blades, greatly improving the safety of the mold when producing the air outlet blades, and reducing the probability of safety accidents when using the mold to produce automobile air outlet blades;

[0013] 2. Lubrication components are arranged outside the guide pillars at the four corners at the bottom of the upper mold base. When in use, lubricating oil is added into the lubricating oil tank through the oil filling port. The upper mold base rises and falls outside the guide pillar, while driving the lubricating oil tank and the lubricating pad soaked with lubricating oil arranged at the bottom to rise and fall outside the guide pillar. The outside of the guide pillar is continuously lubricated by the lubricating pad, thereby ensuring that the upper mold base moves up and down more smoothly on the guide pillar when the mold is used to produce the air outlet blades, reducing the wear of the contact surface between the upper mold base and the guide pillar, thereby ensuring the mold closing accuracy when the mold is injection molding the automobile air outlet blades.
