Embodiment Construction
[0016] Such as Figure 1-4 As shown, the present invention is a special mold for closing the ball pin shell of a double-headed ball hinge, including an upper mold 1, a guide post 2, a lower mold 3 and a positioning sleeve 4, and a cavity is opened on the body 5 of the lower mold 3 6 and the working chamber 7, the lower part of the working chamber 7 is a straight hole, and the upper part is an outwardly inclined taper hole. The diameter is consistent with the diameter of the straight hole, and a through hole perpendicular to its center line is arranged on the side wall of the positioning sleeve 4. During work, the pin shaft passes through the through hole on the side wall of the positioning sleeve 4 and the hole at the end of the ball stud 9, Connect the two together.
[0017] When working, after assembling the pre-prepared ball pin 9 and ball pin shell 8, in order to prevent the ball hinge from running off when closing, install the pin shaft of the positioning sleeve 4 on the...

The invention relates to a special die for closing a double-end spherical hinge ball pin shell, which solves the problem of no mature pressing method for an integrally-formed spherical hinge at present. The special die comprises an upper die, guide posts, a lower die and a positioning sleeve, wherein a cavity and a working cavity are formed in a body of the lower die, a straight hole is formed in the lower part of the working cavity, a conical hole which is inclined outwards is formed in the upper part of the working cavity, the straight hole is connected with the working cavity, the diameter of the straight hole is consistent with that of the small end of a ball pin shell which is not pressed, the diameter of the positioning sleeve is consistent with that of the straight hole, a through hole which is perpendicular to the center line of the positioning sleeve is formed in the side wall of the positioning sleeve, and during operation, a pin shaft passes through the through hole in the side wall of the positioning sleeve and the hole in the end of a ball pin so as to connect the positioning sleeve and ball pin into a whole. By utilizing the special die, the purpose of tight fitting of the ball pin shell and the ball pin can be achieved, the integrality of the ball pin shell is guaranteed, and the product reliability is increased.
Description
[0001] Technical field: [0002] The invention relates to a special mold for closing the ball pin shell of a double-headed ball hinge. [0003] Background technique: [0004] Double-headed ball hinges are widely used in suspension systems and have strong reliability and maintainability. At present, for the closing of the ball pin shell of the double-headed ball hinge, the method often used is to process the pin shell separately, and then put the ball stud into the ball pin shell and press it as a whole. In the case of precise fit, it is often required that the ball pin housing adopts an integral structure so that the ball hinge is integrally formed to achieve the purpose of compact structure. But for integrally formed ball hinges, there is no mature press-fitting method at present. [0005] Invention content: [0006] The invention solves the problem that there is no mature press-fitting method for integrally formed ball hinges by providing a special mold. [0007] The pres...
