In the description of the present utility model, the meaning of "a plurality" is two or more, unless explicitly defined otherwise.

Referring to fig. 1 to 3, the present utility model provides an upper die with dust collection function, which is mainly applied to a punching die (punching machine) of a flexible circuit board, and of course, the upper die can also be applied to other machine equipment.

The upper die comprises: the base 10 and the punch 20, the base 10 mainly plays a bearing and supporting role. The punch 20 is disposed on the base 10, most of the punch 20 is disposed in the base 10, only a punch portion 21 at the lower end of the punch 20 is exposed from the bottom surface of the base 10, and when the upper punch is pressed down, the punch portion 21 punches a workpiece.

The dust hood 30 having the downward opening is provided on the base 10, and the dust hood 30 is not limited to be fixed on the bottom surface of the base 10, but may be fixed on other surfaces of the base, as long as the dust hood 30 covers the punch 21.

The dust collecting cover 30 has a dust collecting space 301 in the inner space, the punch 21 is located in the dust collecting space 301, the dust collecting cover 30 is provided with a dust collecting hole 302 communicated with the dust collecting space 301, a suction nozzle or a suction pipe can be arranged at the position of the dust collecting hole 302, the other end of the suction nozzle or the suction pipe is communicated with a negative pressure machine, and the negative pressure machine works to suck impurities such as waste scraps in the dust collecting space 301. Through being equipped with dust cage 30 in the periphery of drift portion 21, when the drift portion 21 punches a hole the work piece, the sweeps impurity etc. that produce can collect in dust collecting space 301, sweeps impurity etc. are being sucked away through dust absorption hole 302, guarantee the cleanliness factor on work piece surface and the cleanliness factor on drift portion surface to effectively avoid processing in-process, sweeps remain on work piece surface or drift portion surface, prevent then in follow-up processing in-process, produce the damage to the work piece, thereby promote the goodness ratio of product.

In one embodiment of the present utility model, the dust hood 30 includes a main body hood 31 and an elastic hood 32, and the main body hood 31 is provided on the bottom surface of the base 10, and optionally, the main body hood 31 is screwed to the bottom surface of the base 10. The main body cover 31 is made of hard material, preferably, the main body cover 31 is made of metal material, which ensures structural strength and heat dissipation. The dust collection holes 302 penetrate through the inner and outer surfaces of the outer wall of the main body cover 31, and the size and number of the dust collection holes 302 can be set according to practical requirements. The elastic cover 32 is disposed at the lower end of the main body cover 31, the elastic cover 32 is made of an elastic material, and preferably, the elastic cover 32 is made of a polyurethane material. When the upper punch die is pressed downwards to punch, the elastic cover 32 can contact the workpiece, and the elastic cover 32 made of elastic materials can elastically deform, so that the damage to the workpiece caused by hard pressing is effectively avoided.

The bottom surface of the elastic cover 32 is located below the bottom surface of the punch portion 21. When the upper punch die is used for pressing and punching, the bottom surface of the elastic cover 32 firstly contacts the workpiece, after the elastic cover 32 is elastically deformed, the bottom surface of the punch head 21 contacts the workpiece, so that the elastic cover 32 is ensured to be tightly pressed on the surface of the workpiece, gaps between the elastic cover 32 and the workpiece are effectively avoided, and scraps generated in the punching process are prevented from escaping out of the dust collecting cover.

Illustratively, the bottom surface of the main body cover 31 is convexly provided with a positioning boss 311, and the inner wall of the elastic cover 32 is elastically abutted against the outer wall of the positioning boss 311. Optionally, the positioning boss 311 is annular, and correspondingly, the elastic cover 32 is annular, which is to be understood that the diameter of the circular hole inside the elastic cover 32 is slightly smaller than the diameter of the positioning boss 311, and the elastic cover 32 is sleeved on the positioning boss 311 after being pulled to be larger, so that the elastic cover 32 is tightly clamped on the positioning boss 311 under the action of elastic force. Of course, the structure of the elastic cover 32 to be connected to the main body cover 31 is not limited thereto, and may be connected by other structures.

The main body cover 31 and the elastic cover 32 are integrally connected, which means that the elastic cover 32 can be integrally formed on the main body cover 31 by vulcanization injection molding. Or, the main body cover 31 and the elastic cover 32 are connected in a split type, and the split type structure is more beneficial to replacement and maintenance of subsequent parts.

In one embodiment of the present utility model, the punch segment 21 is sleeved with an elastic glue 40, and the elastic glue 40 is elastically deformable, preferably, the elastic glue 40 is made of polyurethane material. The bottom surface of the elastic glue 40 is provided with a gland 50, the gland 50 is preferably made of metal materials, the gland 50 is made of hard materials, workpieces are effectively prevented from being attached to the gland 50, and the workpieces are prevented from being carried up when the upper punch is lifted. The upper and lower surfaces of the pressing cover 50 are penetrated with a through hole 501 through which the punch part 21 passes.

In the initial state, the bottom surface of the dust cap 30 is located below the bottom surface of the pressing cover 50. When the upper punch die is used for pressing and punching, the elastic cover 32, the gland 50 and the punch part 21 are sequentially contacted with a workpiece, and when the gland 50 is contacted with the workpiece, the gland 50 presses the elastic glue 40 to promote the elastic glue 40 to deform and shorten, namely the gland 50 moves upwards, so that the punch part 21 extends out of the position of the through hole 501 to punch the workpiece. After punching is completed, the upper punch die rises, the punch head 21, the gland 50 and the elastic cover 32 are sequentially separated from the workpiece, after the gland 50 is separated from the workpiece, the elastic rubber 40 is elastically restored, and in the elastic restoration process of the elastic rubber 40, the elastic rubber 40 drives the gland 50 to move downwards, so that the workpiece is pushed to be separated from the upper punch die, the upper punch die is prevented from carrying the workpiece, and the stripping is more convenient.

Illustratively, the upper end surface of the gland 50 is provided with a positioning ring 51 protruding upwards, the upper and lower surfaces of the elastic glue 40 are penetrated with a mounting hole 401, and the inner wall of the upper end of the mounting hole 401 is in interference fit with the outer wall of the upper end of the punch part 21; the positioning ring 51 is inserted into the lower end of the mounting hole 401, and the outer wall of the positioning ring 51 is in abutting fit with the inner wall of the lower end of the mounting hole 401.

The utility model also provides a punching die, which comprises the upper punching die. The punching die adopts all the technical schemes of all the embodiments, so that the punching die has all the beneficial effects brought by the technical schemes of the embodiments, and the details are not repeated here.

The foregoing description of the preferred embodiments of the utility model is not intended to be limiting, but rather is intended to cover all modifications, equivalents, and alternatives falling within the spirit and principles of the utility model.
