Matching structure of combined mold and punching machine for manufacturing flexible circuit board

[0020] Examples:

[0021] See figure 1 , The upper mold 1 and the lower mold 2 are given, and an upper mold handle 11 whose structure is not restricted by the figure is fixed on the end face of the end facing outward when the upper mold 1 is in use, and the lower mold 2 is in use A lower mold handle 21 whose structure is not restricted by the figure is fixed on the end surface of one end facing downward. The upper and lower mold handles 11 and 21 are in this embodiment a handle or pull tab structure, but they can also be a gourd head-shaped handle.

[0022] The press platform 3, the upper mold base 5 and the lower mold base 4 of the punching machine are given. On the press platform 3 and located in the center position in the width direction, a screw is opened from one end of the press platform 3 to the other end. The moving groove 31, the cross-sectional shape of the screw moving groove 31 is a T-shape of an English letter, more precisely, a T-shape inverted by 180°. Both ends of the lower mold base 4 are equipped with a fixed foot 42 (also called a presser foot). Preferably, the fixed foot 42 has a 7-shaped or L-shaped shape, which passes through a screw 421 and corresponds to the aforementioned screw moving groove. The position of 31 is fixed with the press platform 3 and is defined by the nut 4211, that is, the nut 4211 is screwed to the end of the screw 42 protruding from the fixing foot 42. The upper mold base 5 corresponds to the upper side of the lower mold base 4 through a set of four guide pillars 51 in a vacant state. As shown in the figure, the lower end of the set of guide pillars 51 is fixed with the lower mold base 4, and The upper end is slidingly fitted with the upper mold base 5 through a guide sleeve 511. The guide sleeve 511 is fixed in the guide sleeve hole at the corner of the upper mold base 5, and a buffer 512 filled with a spring is sleeved on the guide post 51.

[0023] As the technical point of the technical solution provided by the present invention, a lower mold drawer mechanism 6 is provided on the surface of the aforementioned lower mold base 4 facing the upper mold base 5. Similarly, the upper mold base 5 faces a side of the lower mold base 4 An upper mold drawer mechanism 7 is provided on the side surface, and the upper and lower mold drawer mechanisms 7, 6 correspond to each other. The aforementioned upper mold 1 is pluggable and compatible with the upper mold drawer mechanism 7, and the aforementioned lower mold 2 is pluggably matched with the lower mold drawer mechanism 6.

[0024] The preferred, but not absolutely limited, structure of the aforementioned lower mold drawer mechanism 6 is as follows: It includes a pair of lower mold guide rails 61 and a first back baffle 62. A pair of lower mold guide rails 61 are spaced apart from each other and parallel to each other. The width of the lower mold 2 is adapted to each other, and each lower mold guide rail 61 constitutes a lower mold guide groove 611, and a pair of lower mold guide grooves 611 correspond to each other (in a face-to-face state). In this embodiment, the cross-sectional shape of the pair of lower mold guide rails 61 is L-shaped, but it can also be U-shaped with a cross-sectional shape that is deflected by 90°. The pair of lower mold guide rails 61 can be fixed to the lower mold frame 4 by first fixing screws 612. One end of the first rear baffle 62 is fixed to the end of one of the aforementioned pair of lower mold rails 61 by the second fixing screw 621, and the other end is also fixed to the end of one of the aforementioned pair of lower mold rails 61 by the second fixing screw 621. Fix the end of the other one of the lower mold rails 61 to the end end of the lower mold rail 61 of the pair of lower mold rails 61 by the first rear baffle plate 62. The end port) is blocked, and the front end ports of the lower mold rail groove 611 of the pair of lower mold rails 61 are constituted as open ends. The so-called open end refers to the end that is not closed (in use, it faces outward, that is, faces the operator One end). When the lower mold 2 shown in the figure is inserted between the pair of lower mold guide rails 61 from the open end, it slidably fits with the lower mold guide grooves 611 of the pair of lower mold guide rails 61. The lower mold 2 is pushed in following the lower mold guide groove 611, and when it touches the first rear baffle 62, it indicates that it is pushed in place. In order to prevent the lower mold 2 from moving outward from the lower mold rail groove 611 during operation, it is used on the lower mold frame 4 and corresponding to the aforementioned open ends of the lower mold rail groove 611 of the pair of lower mold rails 61. The lower mold limit block 41 is fixed by the third fixing screw 411. When the lower mold 2 is matched with the pair of lower mold guide rails 61, that is, after being inserted into the pair of lower mold guide grooves 611, the lower mold limit block 41 limits its end surface ( figure 2 Show).

[0025] See you figure 1 The preferred but not absolutely limited structure of the aforementioned upper mold drawer mechanism 7 is as follows: It includes a pair of upper mold guide rails 71 and a second back baffle 72. A pair of upper mold guide rails 71 are spaced apart from each other and parallel to each other, and are also connected to each other. The aforementioned pair of lower mold guide rails 61 correspond to each other. The distance between the pair of upper mold guide rails 71 should match the width of the upper mold 1, and each upper mold guide rail 71 is connected to the upper mold base 5 with a fourth fixing screw 712. fixed. The cross-sectional shape of the pair of upper mold rails 71 is as described for the lower mold rail 61. One end of the second back plate 72 is fixed to the end of one of the upper mold rails 71 of the pair of upper mold rails 71, and the other end is to the end of the other of the pair of upper mold rails 71 The end port of the upper mold rail groove 711 of the pair of upper mold rail 71 is blocked by the second back plate 72, and the front end port of the upper mold rail groove 711 of the pair of upper mold rail 71 is configured as Open end, the concept of open end refers to the unclosed end. When the upper mold 1 shown in the figure is inserted between the pair of upper mold guide rails 71 from the open end, it is slidably fitted with the upper mold guide grooves 711 of the pair of upper mold guide rails 71. The upper mold 1 is pushed in along the upper mold guide groove 711, and when it touches the second back baffle 72, it indicates that it is pushed in place. In order to prevent the upper mold 1 from moving outwards from the upper mold rail groove 711 during the working process, the upper mold frame 5 and the position corresponding to the aforementioned opening end of the upper mold rail groove 711 of the upper mold rail 71 are used for each The fifth fixing screw 521 fixes an upper mold limiting block 52. When the upper mold 1 is matched with the pair of upper mold guide rails 7, that is, after being inserted into the pair of upper mold guide grooves 711, the upper mold limit block 52 defines its end surface ( figure 2 Show).
