Embodiment 1）

[0023] like figure 2 and image 3 As shown, the combined ejector rod of this embodiment includes a sleeve rod 1, a driving rod 2, a driven rod 3 and a sealing ring 4. The sleeve rod 1 is a two-stage structure, including a sleeve rod upper section 11 and a sleeve rod lower section 12. The upper section 11 of the rod and the lower section 12 of the sleeve rod are hollow rods with one end open and one end perforated. The open ends of the upper section 11 of the sleeve rod and the lower section 12 of the sleeve rod are respectively provided with external threads and internal threads. The open ends of the lower section 12 are relatively connected and combined to form a complete sleeve rod 1; the upper section 11 of the sleeve rod is provided with a refueling port 14, and the lower section 12 of the sleeve rod is provided with a mounting seat 13, and the mounting base 13 is provided with a mounting hole. Through the mounting hole The sleeve rod 1 can be installed on the mould, usi...

Abstract

The invention relates to a combined ejector rod which comprises a loop bar, a driving rod, a driven rod and sealing rings, wherein the loop bar is a rod piece with interior being hollow and two ends being opened, the driving rod and the driven rod are respectively inserted into the holes at two ends of the loop bar, and the sealing rings are respectively arranged at the connecting part of the driving rod and the loop bar and at the connecting part of the driven rod and the loop bar. According to the ejector rod disclosed by the invention, by utilizing hydraulic transmission, a conventional ejector rod is divided into two parts which are not in contact with each other, so that the ejector rod still has good stability even if in a die with great depth, and a product can be smoothly ejected out.

Description

technical field [0001] The invention relates to an ejector pin, in particular to an ejector pin inside a mold for ejecting products. Background technique [0002] After the mold product is formed, in order to release the product smoothly, it is necessary to use an ejection mechanism to eject the product from the mold. figure 1 It is a schematic diagram of the working principle of a common mechanical ejection mechanism in the mold. The guide post 5 drives the top plate 6 to drive the ejector rod 7 to move upward to eject the product 8 . [0003] This traditional ejection mechanism has a simple structure and is widely used, but this ejection mechanism is not suitable for larger molds in depth. Because the movement of the overly long ejector pin in the mold is unstable, ejection is difficult. Contents of the invention [0004] The technical problem to be solved by the present invention is: in order to solve the problem that the traditional ejector pin is difficult to eject ...
