Problems solved by technology
The traditional mold oil cylinder is directly connected to the thimble plate, but when repairing or disassembling the thimble plate, the oil cylinder needs to be removed together, which is troublesome, so the applicant designed a connection block for the connection between the oil cylinder and the thimble plate, but in practice In use, since the connecting sleeve and the cylinder rod of the oil cylinder are matched with a circular sleeve rod, the connecting sleeve is easy to rotate, which affects the ejection accuracy of the cylinder.

Embodiment Construction
[0009] The invention relates to a safety buckle for an injection mold oil cylinder connecting sleeve, such as figure 1 , figure 2 As shown, it includes mold thimble plate 1 and ejection cylinder 2, connecting sleeve 3 is installed on ejector plate 1, and cylinder rod 4 of ejecting cylinder 2 is connected to connecting sleeve 3. Its main technical feature is that the connecting sleeve 3 is set U-shaped buckle 6, straight faces 7 are arranged on both sides of the oil cylinder rod 4, and the U-shaped buckle 6 blocks the oil cylinder rod 4, and cooperates with the straight faces on both sides of the oil cylinder rod. The main feature of this scheme is that a U-shaped buckle 6 is set on the connecting sleeve 3, the U-shaped buckle 6 clamps the cylinder rod 4, and cooperates with the straight faces 7 on both sides of the oil cylinder rod 4, and the U-shaped buckle is formed. After buckling, when the ejector plate 1 is working continuously, the cylinder rod 4 will not rotate or shi...

A safe buckle of an oil cylinder connection sleeve of an injection mold comprises a mold ejector pin plate and an ejecting oil cylinder. The ejector pin plate is provided with the connection sleeve, an oil cylinder rod of the ejecting oil cylinder is connected with the connection sleeve, the connection sleeve is provided with a U-shaped snap joint, and the two sides of the oil cylinder rod are provided with vertical faces. The U-shaped snap joint clamps the oil cylinder rod and coordinates with the vertical faces on the two sides of the oil cylinder rod. According to the scheme, the safe buckle of the oil cylinder connection sleeve of the injection mold is mainly characterized in that the connection sleeve is provided with the U-shaped snap joint, the U-shaped snap joint clamps the oil cylinder rod and coordinates with the vertical faces on the two sides of the oil cylinder rod, after the U-shaped snap joint is arranged, when the ejector pin plate continuously works, the situation thatthe oil cylinder rod rotates and deviates due to shake generated by up-down ejection actions of the ejector pin plate cannot occur, and therefore the precision of ejection, driven by the oil cylinder, of the ejector pin plate is guaranteed, clamping accidents cannot occur, and safe production is ensured.
Description
technical field [0001] The invention relates to a safety buckle of an oil cylinder connecting sleeve of an injection mold, belonging to the field of injection molds. Background technique [0002] Injection molds are used to produce plastic products, such as large plastic parts such as automobile bumpers. The molds are large in size and heavy in weight. Therefore, when ejecting, most of them use an additional oil cylinder to drive the ejector plate to jack up. The traditional mold oil cylinder is directly connected to the thimble plate, but when repairing or disassembling the thimble plate, the oil cylinder needs to be removed together, which is troublesome, so the applicant designed a connection block for the connection between the oil cylinder and the thimble plate, but in practice In use, since the connecting sleeve and the oil cylinder rod of the oil cylinder are matched by circular sleeve rods, the connecting sleeve is prone to rotation, thereby affecting the ejection ac...
