Description

Thimble batch processing jig structure and assembling and processing method thereof [ Field of technology ] The invention relates to the technical field of mold thimble processing jigs, in particular to a thimble batch processing jig structure and an assembling and processing method thereof. [ Background Art ] In the injection mold, the ejector pin is an important functional mold part for demolding a product, and the top surface of the ejector pin is required to be processed according to the shape of the plastic product due to contact with the plastic product. The top surface of the thimble is usually processed by two modes, namely, manual polishing, namely, after the thimble is assembled into a die, excessive materials at the tops of the thimbles are removed by a polisher, although the cost of the mode is low, the processing time is short, the processing quality is low, namely, the processing quality is rough, the appearance of a formed product is influenced, the die is easy to damage, and the thimble is assembled into the die after the die core and the die carrier are processed, CNC (numerical control) machine tool) is adopted for processing, and although the processing quality is high, the formed product is attractive, but the cost is high, and the processing efficiency is low. In view of the foregoing, it is necessary to provide a batch processing jig structure for thimble and an assembling and processing method thereof to solve the above-mentioned problems. [ Invention ] The invention aims to solve the technical problems that the top surface of a common thimble is usually machined in two ways, namely, after the thimble is assembled into a die, excessive materials at the tops of the thimbles are removed by a grinding machine, but the machining quality is low, namely, the processing is rough, the appearance of a formed product is influenced, the die is easy to damage, and the thimble is assembled into the die after the die core and the die frame are machined, CNC machining is adopted, but the cost is high and the machining efficiency is low. Therefore, the invention provides a thimble batch processing jig structure and an assembling and processing method thereof to solve the problems. The invention solves the technical problems by adopting a thimble batch processing jig structure, which comprises: The upper middle plate is internally provided with at least one group of first positioning holes; The lower middle plate is internally provided with a first positioning group, the first positioning group comprises a first placing groove and a second positioning hole, the first placing groove is arranged on one side of the lower middle plate away from the upper middle plate, and the first placing groove is internally provided with the second positioning hole at a position corresponding to the first positioning hole; the foot pad is fixedly connected between the upper middle plate and the lower middle plate through a first fixing piece; The top plate is fixedly connected to one side, far away from the lower middle plate, of the upper middle plate through a second fixing piece, a second positioning group is arranged in the top plate, the second positioning group comprises a second placing groove and a third positioning hole, the second placing groove is arranged on one side, close to the upper middle plate, of the top plate, and the third positioning hole is formed in the position, corresponding to the first positioning hole, in the second placing groove; the head bush penetrates through a third positioning hole in the second placing groove of the top plate at one side of the head bush, which is far away from the first convex end, and the head bush is fixedly connected between the top plate and the upper middle plate through the first convex end; The tail bushing penetrates through the second positioning hole in the first placing groove of the lower middle plate at one side, far away from the second convex end, of the tail bushing, the tail bushing is fixedly connected between the lower middle plate and the bottom plate through the second convex end, and the outer diameters of the tail bushing and the head bushing are standard sizes; the bottom plate is fixedly connected to the lower middle plate through a third fixing piece. Preferably, the first, second and third fasteners all include, but are not limited to, bolts. Preferably, at least one set of positioning members are arranged among the top plate, the upper middle plate and the foot pad, and among the bottom plate, the lower middle plate and the foot pad, and the positioning members comprise, but are not limited to, positioning pins for uniformly referencing all plates. Preferably, an anti-rotation block is arranged on one side of the tail bushing close to the second convex end and used for preventing the tail bushing and the thimble from rotating.
