Problems solved by technology

[0003] In the extrusion casting process of small extruders, there are many small vertical extruders due to their simple structure and lack of necessary ejection mechanisms. After the mold is opened, the extruded products need to be demolded manually, resulting in low production efficiency and high production costs. , due to the high temperature of the metal extrusion product after extrusion, it is dangerous to use manual demoulding, or the ejector mechanism cannot be pushed in the proper position due to the position limitation, resulting in the extruded product Breakage or cracking occurs, causing damage to extruded products

Embodiment 1

[0021] Example 1: as Figure 1-4 As shown, the metal mold cylinder ejection mechanism of the vertical extruder includes an oil cylinder 10, the oil cylinder 10 is fixed under the upper bottom plate 2, the oil cylinder rod 11 of the oil cylinder is connected with the ejector plate 5, and the ejector bottom plate 7 is arranged on the ejector plate 5 and the lower plate 8, the upper base plate 2 and the lower base plate 8 are connected by two support blocks 3 and the two support blocks are located on both sides of the oil cylinder respectively, the upper base plate 2 is provided with a heat insulation plate I1, and the two support blocks 3 and the lower base plate 8 Insulation board II4 and heat insulation board III6 are respectively arranged between them. One end of the ejector pin 9 is fixedly connected with the ejector pin bottom plate 7, and the other end passes through the through hole on the lower bottom plate 8. The top of the metal mold is fixed on the lower bottom plate 8...

Embodiment 2

[0023] Embodiment 2: The structure of the device of this embodiment is the same as that of Embodiment 1, except that the head of the ejector pin 9 is provided with a flange, which is fixed on the ejector pin bottom plate 7 in the form of a flange, and the upper bottom plate 2 and the support block 3 are connected by bolts.

[0024] When the above-mentioned device is used, after the extrusion process is completed, the mold is opened; driven by the thrust of the oil cylinder, the oil cylinder rod 11 pushes the thimble panel 5, so that the thimble bottom plate 7 and the thimble 9 move downward, and the thimble 9 contacts the extruded product and extrudes. The pressed product is forcibly released from the mold under the push of the ejector pin 9, so as to complete all the demoulding actions.

[0025] After the above scheme is adopted, the structure is simple, the processing and assembly are easy, the workpiece can be ejected conveniently and reliably, the ejector rod is easy to rep...

Abstract

The invention discloses a vertical extruder metal die oil cylinder ejection mechanism and an ejection method thereof. The vertical extruder metal die oil cylinder ejection mechanism comprises an oil cylinder, the oil cylinder is fixed under an upper bottom plate, an oil cylinder rod of the oil cylinder is connected with an ejection pin face plate, an ejection pin bottom plate is arranged between the ejection pin face plate and a lower bottom plate, the upper bottom plate and the lower bottom plate are connected through two supporting blocks, the two supporting blocks are located on the two sides of the oil cylinder separately, a heat insulation plate I is arranged on the upper bottom plate, a heat insulation plate II and a heat insulation plate III are arranged between the two supporting blocks and the lower bottom plate respectively, one end of each ejection pin is fixedly connected with the ejection pin bottom plate, the other ends of the ejection pins penetrate through the lower bottom plate, and the top of a metal die is fixed to the lower bottom plate. According to the vertical extruder metal die oil cylinder ejection mechanism and the ejection method thereof, the structure issimple, machining and assembling are easy, a workpiece can be conveniently and reliably ejected out, an ejection rod is easy to replace, and a set of an ejection system is suitable for multiple setsof dies; and in addition, the die structure is simplified, the die difficulty and manufacturing cost are reduced, the die development cycle is shortened, and the economical benefit is improved.

Description

technical field [0001] The invention belongs to the technical field of extrusion casting of vertical extruders, in particular to an ejection mechanism of a metal die oil cylinder of a vertical extruder and an ejection method thereof. Background technique [0002] The movement direction and discharge direction of the main components of the vertical extruder are perpendicular to the ground, so the floor area is small, but it requires a higher workshop and a deeper pit. The latter is to ensure that the extruded tube is straight and rounded for subsequent pickling cold rolling or cored head drawing. Because the moving parts move vertically on the ground, the wear is small, the parts are deformed evenly after being heated and expanded, the center of the extruder is not easy to be out of balance, and the eccentricity of the tube is small. The maximum capacity of the extruder is more than 15MN, and the commonly used one is 6-10MN. It is mainly used for the production of small-size...
