Description
Technical field
The utility model is related to mould applications, more particularly to a kind of novel trimming mold.
Background technology
Trimming Die is device more commonly used in parts machining, mainly by the cooperation between punch-pin and cavity plate,
The part on parts blank is cut off, and then completes deburring shaping.During die trimming, due to the type of parts blank
Face is mostly curved surface, and the curvature of every part in the type face is not quite similar, and in order to ensure deburring quality, the direction for repairing punching is generally wanted
It asks the direction on surface at the deburring with parts consistent, or carries out the adjustment in zone of reasonableness, it is complete to reduce parts machining
At the burr of rear formation.
However, for the larger parts of surface curvature amplitude of variation, when deburring usually require multiple sets of molds carry out it is multiple
Trimming just can guarantee the size of part, cause that the production cost increases.
Invention content
The purpose of this utility model is to provide a kind of novel trimming molds that production cost is low.
The purpose of this utility model is achieved through the following technical solutions：
A kind of novel trimming mold, including upper die holder, retainer frame and lower die holder, the upper die holder bottom surface middle part are machined with recessed
Slot, groove is interior to be equipped with upper mold core, and die shank is equipped at the top of the upper mold core, is connect with forcing press across upper die holder at the top of die shank, institute
It states upper mold core to be spliced by multiple knife tools, cavity slot, the lower die holder surface middle part is machined in the middle part of upper mold core bottom surface
Equipped with lower mold core, the punch-pin to match with cavity slot bottom facial contour is equipped with above lower mold core, the punch-pin is by multiple deburring tool aprons
It is spliced, retainer frame is provided on the lower die holder on the outside of lower mold core, is machined with and lower mold core side wall wheel in the middle part of the retainer frame
The through-hole that exterior feature matches, retainer frame bottom are equipped with air cushion bar, and retainer arch unloads material nail and multiple limited posts equipped with multiple.
Guide plate is equipped between retainer frame and lower mold core.
The utility model is by being arranged cavity slot and in the punch-pin of cavity slot cooperation, workpiece being made to be surrounded with cavity slot and punch-pin
Profile match, to improve the stability of workpiece, further increase die trimming precision, reduce production cost；Lead to simultaneously
Crossing setting and unloading the gentle lining bar of material nail makes workpiece and mold quick separating, raising processing efficiency.

Specific implementation mode
Embodiment
As shown in Figure 1 to 4, novel trimming mold provided in this embodiment includes upper die holder 1, retainer frame 4 and lower die holder
5,1 bottom surface of upper die holder middle part processing fluted 11, groove 11 is interior to be equipped with upper mold core 2, and 2 top of the upper mold core is equipped with die shank
3,3 top of die shank is connect across upper die holder 1 with forcing press, and the upper mold core 2 is spliced by multiple knife tools 21, upper mold core
Cavity slot 22 is machined in the middle part of 2 bottom surfaces, 5 surface middle part of the lower die holder is equipped with lower mold core 51, and 51 top of lower mold core is equipped with and type
The punch-pin 52 that 22 bottom profile of cavity groove matches, the punch-pin 52 are spliced by multiple deburring tool aprons 53,51 outside of lower mold core
Lower die holder 5 on be provided with retainer frame 4, be equipped with guide plate 54 between retainer frame 4 and lower mold core 51, the middle part of the retainer frame 4 plus
Work has the through-hole 41 to match with 51 side wall profile of lower mold core, 4 bottom of retainer frame to be equipped with air cushion bar 42, and 4 top of retainer frame is equipped with
It is multiple to unload material nail 43 and multiple limited posts.
The application method of the utility model：
Workpiece is placed on lower die holder 5 first, 1 downlink of upper die holder is then controlled, when 1 bottom surface of upper die holder is contacted with workpiece
Afterwards, forcing press drives the drive of die shank 3 to make 2 downlink of upper mold core, and cooperation punch-pin 52 is by workpiece punching press to cavity slot 22, then upper mold
The deburring tool apron 53 on knife tool 21 and lower mold core 51 on core 2 carries out deburring shaping to workpiece, 1 uplink of subsequent upper die holder,
Workpiece is stuck on punch-pin 52 at this time, and retainer frame 4 moves up under the drive of air cushion bar 42, while being unloaded material nail 43 and being jacked up workpiece,
Workpiece is set to be detached with punch-pin 52.
