Embodiment 1

[0041] Please refer to Figure 4 , this embodiment uses the above-mentioned coil synchronous ejector device to demould the coil in the mold, which specifically includes the following steps:

[0042] First, a first annular groove 91 or a first annular protrusion (not shown) is provided along the inner wall of the coil inner mold 9, and a second annular groove 101 or a second annular protrusion is provided along the outer wall of the coil outer mold 10. (not shown);

[0043] Then, the second movable block 51 is pressed against the coil 8 and the coil inner mold 9 at the same time, and the first movable block 41 is put into the second annular groove 101 on the coil outer mold 10 or the second annular protrusion. Below; after the second movable block 51 presses the coil 8 and the coil inner mold 9 at the same time, install the sleeve 7 of the same height on all the guide shafts 3 on the inner synchronous ring 5 to press the inner synchronous ring 5, and then Install the nut 11 o...

Embodiment 2

[0047] In this embodiment, the above-mentioned coil synchronous ejection device is used to demould the coil in the mold, which specifically includes the following steps:

[0048] First, a first annular groove 91 or a first annular protrusion is provided along the inner wall of the coil inner mold 9, and a second annular groove 101 or a second annular protrusion is provided along the outer wall of the coil outer mold 10;

[0049] Next, press the first movable block 41 against the coil 8 and the coil outer mold 10 at the same time, and put the second movable block 51 into the first annular groove 91 of the coil inner mold 9 or below the first annular protrusion After the first movable block 41 presses the coil 8 and the coil outer mold 10 at the same time, install sleeves 7 of the same height on all the guide shafts 3 with the outer synchronous ring 4 to press the outer synchronous ring 4, and then guide Install the nut 11 on the end of the shaft 3 to compress the sleeve 7; plac...

Abstract

The invention discloses a synchronous coil ejector and a method for releasing coils from molds by the aid of the synchronous coil ejector. The synchronous coil ejector comprises a base, a plurality of guide shafts, an outer synchronous ring and an inner synchronous ring. The guide shafts are fixed onto the base, the outer synchronous ring and the inner synchronous ring sleeve the guide shafts, fixing components are arranged on the tops of the guide shafts, a plurality of first movable fixture blocks are arranged on the outer synchronous ring, and a plurality of second movable fixture blocks are arranged on the inner synchronous ring. The synchronous coil ejector and the method have the advantages that the synchronous coil ejector is provided with the inner synchronous ring and the outer synchronous ring, the synchronous rings can slide up and down along the guide shafts fixed onto the base, and the guide shafts and the synchronous rings are matched with one another, so that the consistency of the lifting heights of various points of the synchronous rings can be guaranteed in ejection procedures; mold releasing devices act on the synchronous rings instead of directly ejecting the coil molds, accordingly, the coils can be assuredly stably and safely released from the molds, the cost can be reduced, and the synchronous coil ejector can be operated easily and conveniently.

Description

technical field [0001] The invention relates to a coil demoulding tool and a demoulding method thereof, in particular to a coil synchronous ejection device and a demoulding method thereof. Background technique [0002] Part of the coils in the MR (Nuclear Magnetic Resonance) superconducting magnet are wound separately on the winding mold. The wound coils need to be filled with glue, and finally the glue-filled coils are released from the mold. After the coil is filled with glue, the demoulding force is very large, and special ejection equipment is required. Moreover, due to the large diameter of this coil, multiple points are required to be ejected at the same time (usually 4 points). In order to ensure that the coil is not damaged during the ejection process, multiple ejection points need to generate force synchronously. [0003] Existing ejectors on the market that can guarantee synchronous ejection use independent hydraulic cylinders with displacement sensors, and read ...
