The terms "one embodiment" and "an embodiment" mean "at least one embodiment". The term "another embodiment" means "at least one other embodiment". The terms "first," "second," and the like may refer to different or the same object. Other definitions, whether explicit or implicit, may be included below. The definition of a term is consistent throughout the specification unless the context clearly dictates otherwise.

Fig. 1 schematically shows a mold having a capacitor core. The mold for manufacturing the capacitor core includes an outer mold 1 and an inner mold 2. The outer mould tool 1 may be configured as a hollow cylinder closed at one end and the inner mould tool 2 may be configured as a cylinder. The outer mould tool 1 and the inner mould tool 2 may be arranged concentrically. One end of the inner mould 2 is pressed against the closed end of the outer mould 1, and the other end of the inner mould 2 extends out of the outer mould 1. Resin constituting the capacitor core 3 is filled between the outer mold 1 and the inner mold 2. In order to release the capacitor core 3 from the outer mold 1, the demolding is generally performed using an oil cylinder mechanism as shown in fig. 2. And after the capacitor core 3 is released from the outer mold 1, the capacitor core is taken out of the inner mold 2.

Fig. 2 schematically shows a capacitor core demoulding mechanism according to the prior art. The demolding mechanism comprises a cylinder mechanism with a cylinder 5 and a piston rod 4, a roller assembly 6 and a frame with a one-way stopper 7. The free end of the piston rod 4 is fixedly connected to the end of the inner mould tool 2 protruding from the outer mould tool 1. The cylinder 5 is fixedly arranged relative to the frame. The outer mould tools 1 are fixedly connected to the roller assemblies 6 and are movably supported on the frame by the roller assemblies 6. When the piston rod 4 is extended, the inner mould 2 together with the capacitor core 3 and the outer mould 1 is pushed to the right in fig. 2. At the maximum extension of the piston rod 4, the piston rod 4 in turn drives the inner mould together with the capacitor core 3 to retract, i.e. to move to the left in fig. 2. However, during the retraction of the piston rod 4, the outer mold 1 is prevented from moving leftward by the one-way stopper 7, so that the capacitor core 3 moves leftward with respect to the outer mold 1. After the piston rod 4 reciprocates for a plurality of times, the capacitor core 3 is released from the outer mold 1. With the capacitor core demolding mechanism in the prior art, the capacitor core 3 can move by one reciprocating stroke relative to the outer mold 1 in one reciprocating motion of the piston rod 4.

Fig. 3 schematically shows a capacitor core demoulding device according to the invention. According to the utility model discloses an electric capacity core shedder includes base frame 8, two at least gyro wheels 9, hydro-cylinder mechanism and two times stroke device. The double-stroke device is fixedly connected to the rollers 9 and is mounted movably on the base frame 8 via the rollers 9. The oil cylinder mechanism comprises an oil cylinder 5 and a piston rod 4. The double stroke device is fixedly connected to the piston rod 4 and the inner mould 2 (not shown in fig. 2). The double stroke device is configured to convert the movement of the piston rod 4 into the movement of the inner mold 2, and to make the moving stroke of the inner mold 2 twice the actuating stroke of the piston rod 4.

In the embodiment shown in fig. 3, the double-stroke device comprises a transition bar 10, a connecting head 11 and a pulley assembly. The transition bar 10 has a first section 10a, a second section 10b and a third section 10c. The second and

third sections

10b, 10c are parallel to each other and perpendicular to the first section 10a. Both ends of the first segment 10a are fixedly connected with the second segment 10b and the third segment 10c, respectively. The embodiment of fig. 3 comprises 4 rollers 9, two rollers 9 being fixed to each of the second section 10b and the third section 10c. It is also conceivable that the capacitor core stripping means comprise only two rollers 9, both rollers 9 being fixed to the third section 10c of the transition bar 10 and movably supporting the transition bar 10 on the base frame. It is also envisaged that the capacitor core stripping means comprises three rollers 9, two of which rollers 9 are fixed to the third section 10c of the transition bar 10 and one roller 9 is fixed to the second section 10b of the transition bar 10. Of course, it is also conceivable to provide and arrange a larger number of rollers 9, as long as they are able to movably support the transition bar 10 and thus the double stroke device on the base frame 8. A connection 11 is fastened to the first section 10a, by means of which connection 11 the double stroke device is rigidly connected to the inner mold part 2.

As shown in fig. 3, the first, second and

third sections

10a, 10b, 10c of the transition bar 10 form a rectangle that is open to the left. The sheave assembly is disposed within the rectangle. The pulley assembly comprises two sets of sprockets 12 and a chain 13. Two sets of sprockets 12 and chains 13 are arranged on either side of the axis of the cylinder 5. The two chain wheels 12 are connected to one another in a positionally fixed manner by a chain wheel connecting rod. The sprocket connecting rod is fixedly connected to the free end of the piston rod 4 perpendicularly with respect to the piston rod 4. In the embodiment of fig. 3, the free end of the piston rod 4 is connected at the midpoint of the sprocket connecting rod. In the first set of sprockets 12 and the chain 13, both ends of the chain 13 are fixed to the second section 10b of the transition bar 10 and the side wall of the oil cylinder 5, respectively, and are wound around the sprockets 12. In the second set of the sprockets 12 and the chain 13, both ends of the chain 13 are fixed to the third section 10c of the transition lever 10 and the side wall of the cylinder 5, respectively, and are wound around the sprockets 12. The pulley assemblies in fig. 3 are arranged symmetrically with respect to the axis of the ram mechanism.

Thus, when the piston rod 4 moves to the right by the stroke L, the end of the chain 12 connected to the transition rod 10 moves to the right by the stroke 2L, so that the connector 11 carries the inner mold 2 together with the capacitor core 3 and the outer mold 1 to the right by the stroke 2L (not shown in fig. 3). When the piston rod 4 is extended to its maximum stroke, the double stroke device can be pushed back to the left in fig. 3 by the operator until the piston rod 4 returns to its initial position. Thereby, the inner mold 2 is driven and the condenser core 3 is ejected leftward from the outer mold 1 by a length of 2L. In order to facilitate the pushing back of the double stroke device by the operator, a handle can be provided, which can be fixedly connected to the connector 11 or the transition rod 10 in a suitable position. Of course, the handle may be provided at other locations on the double stroke device, as long as it facilitates the operator to push back. Furthermore, instead of manually driving the roller 9 in motion, an additional drive can also be provided for the roller 9 in order to return the piston rod 4 into the initial position.

It should be understood that although the specification has been described in terms of various embodiments, not every embodiment includes every single embodiment, and such description is for clarity purposes only, and it will be appreciated by those skilled in the art that the specification as a whole can be combined as appropriate to form additional embodiments as will be apparent to those skilled in the art.

The above description is only exemplary of the present invention, and is not intended to limit the scope of the present invention. Any equivalent changes, modifications and combinations that may be made by those skilled in the art without departing from the spirit and principles of the invention should be considered within the scope of the invention.
