Detailed Description

As shown in figures 1-11, the injection mold row-position inner inclined ejection mechanism comprises a front template 1, a rear template 2, a rear mold insert 3, a row position 4, a row position seat 5, a pressing block 6, an inclined ejection 7, a guide block 8, an inclined guide pillar seat 9, an inclined guide pillar 10, a front mold insert needle 11, a front mold insert 12 and an injection product 13.

As shown in fig. 5 and 9-11, the surface rib of the injection molding product 13 is provided with an inverted structure, and the row position 4, the inclined top 7 and the front mold insert 11 are in three-responsibility matching contact with the inverted structure of the corresponding injection molding product 13.

As shown in fig. 1 to 11, when the mold is opened, the front mold plate 1 moves vertically upwards and away from the rear mold plate 2, the front mold plate 1 drives the front mold insert 12 and the inclined guide post seat 9 to move vertically upwards, the front mold insert 12 drives the front mold insert needle 11 to move vertically upwards, the front mold insert needle 11 is separated from contact with an injection molding product 13, the inclined guide post seat 9 moves vertically upwards and drives the inclined guide post 10 to move upwards, the inclined guide post 10 drives the slide seat 5 to move horizontally rightwards along a sliding groove on the rear mold plate 2, the slide seat 5 drives the slide 4 to move horizontally rightwards and separate from contact with the injection molding product 13, in the process, the inclined top 7 moves horizontally forwards due to the limit of an L-shaped guide groove formed on the guide block 8, and after the right end of the inclined top 7 protrudes to the corner of the L-shaped guide groove, the inclined top 7 moves horizontally rightwards along with the slide 4 until the inclined top 7 completely moves out of the area above the injection molding product 13, and core pulling action at the back-off position is finished.

After the injection molding cycle is finished, the front template 1 vertically moves downwards to be in matched contact with the rear template 2, the front template 1 drives the front die insert 12, the front die insert needle 11, the inclined guide pillar seat 9 and the inclined guide pillar 10 to move downwards, the front die insert 12 is matched and contacted with the rear die insert 3, the front die insert needle 11 moves to the initial position, the inclined guide pillar 10 moves downwards to drive the row seat 5 and the row seat 4 to horizontally move leftwards, and the row seat 4 drives the inclined roof 7 to horizontally move leftwards and then horizontally move backwards to the initial position so as to prepare for the next injection molding cycle. The mechanism is characterized in that the inclined top is arranged in the row position, so that the internal space layout of the injection mold is optimized, and the core pulling and demolding at the back-off position of the injection product can be realized.

The foregoing is illustrative of the present utility model and is not to be construed as limiting thereof.
