Description

Technical Field

[0001] The utility model relates to the field of automobile accessories, in particular to a large slider one-to-two downward inclined core-pulling mechanism for an injection mold of a lamp base. Background Art

[0002] After the injection molding of the headlight base or interior trim is completed, demolding operation is required, and the meaning of the one-to-two large sliders in the injection mold is that a large slider structure drives two small sliders to move, thereby playing a double locking limit or canceling limit operation at the same time, which can not only save mold space, but also make the demolding operation simpler and more convenient. Due to the buckle structure of the headlight base or interior trim, it will be limited during demolding, so that the headlight base or interior trim fits with the upper mold or lower mold, and normal demolding operation cannot be performed, thereby affecting the production efficiency and the stability of the mold structure and the service life. Based on this, a large slider one-to-two downward inclined core pulling mechanism is provided, which is convenient for quick demolding, improves demolding production efficiency and mold stability, and prolongs service life.

[0031] Working principle: When in use, first start the cylinder 102 and cooperate with the connecting block 123 to lift the slider support plate 121. Under the reaction force, the large slider 101 can be controlled to move away from the slider support plate 121, and the pressure strip 131 moves along the strip groove, so it can play a role in guiding and limiting and improving stability. Then the large slider 101 moves with the inclined I-block 105, and then the moving block 140 can be controlled to move along the guide groove. As the moving block 140 moves, the core pulling 104 can rise from the extraction hole 150, thereby initially ejecting the workpiece attached to the surface of the first insert 103 and separating it from the first insert 103. At the same time, the second insert 111 cooperates with the ejection block 112 to eject the core pulling block 109 along the inclined guide block 108. At this time, the fixed block 106 and the inclined guide column 107 rise, further ejecting the workpiece out of the mold, thereby improving the demolding efficiency.
