AI Technical Summary
In the existing technology, the undercut space on the outside of the BOSS column of the product is small, and the ordinary inclined ejector structure design cannot be adopted, resulting in a slingshot ejector pin ejection process that is complex and costly to process.
A straight top demoulding mechanism with a slider is adopted. When the straight top drives the first slider and the second slider to rise in the straight top groove, the thrust piece pushes the sliders away from each other. Stable movement is achieved through the cooperation of the guide rod and the guide groove, and the side wall of the slider cooperates with the inclined surface of the straight top groove to realize the disengagement of the undercut.
It realizes convenient ejection of products, reduces processing difficulty and cost, and improves processing efficiency.

[0029] The present disclosure will be described in detail below with reference to the accompanying drawings and in conjunction with embodiments.
[0030] like Figure 1-5As shown, a straight ejection mechanism with a slider comprises a movable mold 100, a straight ejector 200, a boss column inlay pin 300, a first slider 201, a second slider 203 and a thrust piece 204. A straight ejector groove is provided on the movable mold 100, and the straight ejector 200 is passed through the straight ejector groove. The straight ejector 200 is fixed to the ejector plate through the movable mold 100. The straight ejector groove is provided so that the straight ejector 200 can move in the movable mold 100 to perform an ejection action; the boss column inlay pin 300 is connected to the straight ejector 200, and the boss column inlay pin 300 can move on the straight ejector 200 but not eject; the straight ejector 200 is provided with a receiving groove to accommodate The receiving groove is connected to the straight top groove, and the first slider 201 and the second slider 203 are both in the receiving groove. The first slider 201 and the second slider 203 are arranged opposite to each other, and the thrust piece 204 is between the first slider 201 and the second slider 203. The side walls of the first slider 201 and the second slider 203 are arranged at an angle, and an inclined surface is provided on the side wall of the straight top groove. The slope of the side wall of the first slider 201 and the second slider 203 corresponds to the slope of the inclined surface; when the straight top 200 drives the first slider 201 and the second slider 203 to rise from the straight top groove, the thrust piece 204 pushes the first slider 201 and the second slider 203 away from each other.
[0031] Furthermore, the thrust piece 204 is a spring; a first groove 2012 is provided on the first slider 201, and a second groove 2032 is provided on the second slider 203. The first groove 2012 and the second groove 2032 are arranged opposite to each other. One end of the thrust piece 204 is against the first groove 2012, and the other end is against the second groove 2032. The first groove 2012 and the second groove 2032 are used to position the thrust piece 204 to avoid damage to the thrust piece 204 after compression and twisting.
[0032] Furthermore, two guide rods 202 are provided in the accommodating groove, a first guide groove 2011 is provided on the first slider 201, and a second guide groove 2031 is provided on the second slider 203. The two guide rods 202 are respectively passed through the first guide groove 2011 and the second guide groove 2031; the guide rod 202 is a cylindrical structure, and the first guide groove 2011 and the second guide groove 2031 are both waist-shaped holes. The first guide block and the second guide block can only move 2 mm with the cooperation of the guide rod 202 and the guide groove.
[0033] A first guide block is provided on the first slider 201, a second guide block is provided on the second slider 203, and a sliding groove for the first guide block and the second guide block to move is provided on the inner wall of the accommodating groove; the first guide block and the second guide block are T-shaped structures, and the sliding groove is a T-shaped groove. The cooperation between the guide block and the sliding groove makes the movement of the first slider 201 and the second slider 203 more stable, and limits the movement trajectory of the first slider 201 and the second slider 203.
[0034] After the product 400 is formed, after the mold is opened and before it is ejected, when the product 400 is ejected, during the ejection process of the straight ejector 200, the first slider 201 and the second slider 203 are driven by the thrust piece 204 to slowly slide outward along the inclined surface of the side wall of the straight ejector groove and disengage from the inverted BOSS column until the inverted BOSS column is completely disengaged. After the product 400 is completely ejected into place, the product 400 can be taken out of the straight ejector 200 normally.
[0035] After the product 400 is taken out, when the top plate retreats, the top plate drives the straight top 200 to move downward, thereby driving the straight top 200 to slowly return to the original position of the straight top groove on the movable mold 100. During the process of returning to the original position, the outer inclined surfaces of the first slider 201 and the second slider 203 hit the inclined surface of the side wall of the straight top groove. Under the action of the inclined matching surface, the first slider 201 and the second slider 203 are forced to resist the force of the thrust piece 204 and slowly close together until they return to their original position. The mold can then begin to be closed.
[0036] The above descriptions are merely some preferred embodiments of the present disclosure and an explanation of the technical principles employed. Those skilled in the art should understand that the scope of the utility model disclosed herein is not limited to the technical solutions formed by a specific combination of the above-mentioned technical features, but should also encompass other technical solutions formed by any combination of the above-mentioned technical features or their equivalents without departing from the concept of the utility model. For example, a technical solution formed by replacing the above-mentioned features with (but not limited to) technical features with similar functions disclosed in the embodiments of the present disclosure.
