Abstract
A kind of clamp fixture for processing core rod, it is characterized in that: the frock matrix comprising cuboid, there is the locating slot of two transverse directions apart from upper and lower dual-side equal height position at the leading flank of described matrix, the trailing flank of described matrix and leading flank two locating slot relative positions also each to there being a locating slot, equidistantly have several through holes through front and back locating slot, with internal thread in described through hole, pilot pin with internal thread coupling is installed in described each through hole, described pilot pin length is greater than the degree of depth of through hole, the rear side of described pilot pin is furnished with nut, the utility model design is ingenious, by the core pieces that the cooperation positioning and locking of screens screw bolt and nut is to be processed, coordinates grinding machine, can process the front of combined type mold core block, the utility model structure is simple, practical, greatly improves the production efficiency of core rod processing and the precision of core rod.
Description
Technical field
The utility model relates to field of machining, is specifically related to a kind of clamp fixture for processing core rod.
Background technology
Core rod, as the precision component of mold center's position key running, is directly connected to the price of mold use life-span and mould.Carbide alloy is especially with the material for making core rod that the carbide alloy of wolfram steel is more common at present, and it has high rigidity, high strength, corrosion-resistant, the feature that the high temperature resistant and coefficient of expansion is little, and this also makes wolfram steel core rod difficulty of processing large, and cost is high.Therefore in use how to extend the service life of core rod, the production cost saving enterprise is particularly important.
The core rod of existing a kind of processing rigid alloy is integrated core rod (as shown in Figure 1), when mould is at converted products, raw material pressurized rear mold in-core chamber will produce very large pressure, this not only can cause very large impact to core rod, core rod pressurized easily ruptures, increase the production cost of enterprise, first core rod is improved as combined type mold core, be made up of multiple core pieces (as shown in Figure 2), for carrying out the processing of this core rod, the core pieces (as shown in Figure 3) of frock clamp to combination is needed to carry out meticulous polishing, for realizing the polishing processing of core pieces, needing to develop multiple clamping apparatus frock coordinates grinding machine each face to core pieces to process, to reach good combined effect.
Utility model content
The utility model, for the problems referred to above, designs a kind of clamp fixture for processing core rod, by using this clamp fixture to coordinate grinding machine to realize the processing of combined type mold core, adopts following technical scheme.
A kind of clamp fixture for processing core rod, it is characterized in that: the frock matrix comprising cuboid, there is the locating slot of two transverse directions apart from upper and lower dual-side equal height position at the leading flank of described matrix, the trailing flank of described matrix and leading flank two locating slot relative positions also each to there being a locating slot, equidistantly have several through holes through front and back locating slot, with internal thread in described through hole, pilot pin with internal thread coupling is installed in described each through hole, described pilot pin length is greater than the degree of depth of through hole, the rear side of described pilot pin is furnished with nut, described clamp fixture is irony.
The utility model design is ingenious, by the core pieces that the cooperation positioning and locking of screens screw bolt and nut is to be processed, coordinates grinding machine, can process the front of combined type mold core block, the utility model structure is simple, practical, greatly improves the production efficiency of core rod processing and the precision of core rod.

Detailed description of the invention
A kind of clamp fixture for processing core rod, comprise the frock matrix 1 of cuboid, there is the locating slot 2 of two transverse directions apart from upper and lower dual-side equal height position at the leading flank of described matrix 1, the trailing flank of described matrix and leading flank two locating slot relative positions also each to there being a locating slot 3, equidistantly have several through hole 4 through front and back locating slots, with internal thread in described through hole 4, pilot pin 5 with internal thread coupling is installed in described each through hole 4, described pilot pin 5 length is greater than the degree of depth of through hole 4, the rear side of described pilot pin 5 is furnished with nut 6, described clamp fixture is irony.
In the present embodiment, for 6 through holes 4, core pieces is inserted in the locating slot of front side, by location screw bolt and nut lock core pieces, coordinate grinding machine, can process the front of combined type mold core block, the utility model structure is simple, practical, greatly improve the production efficiency of core rod processing and the precision of core rod.
Above a kind of clamp fixture for processing core rod that the embodiment of the present invention provides is described in detail, for one of ordinary skill in the art, according to the thinking of the embodiment of the present invention, all will change in specific embodiments and applications, in sum, this description should not be construed as limitation of the present invention.
Claims (2)
1. one kind for processing the clamp fixture of core rod, it is characterized in that: the frock matrix comprising cuboid, there is the locating slot of two transverse directions apart from upper and lower dual-side equal height position at the leading flank of described matrix, the trailing flank of described matrix and leading flank two locating slot relative positions also each to there being a locating slot, equidistantly have several through holes through front and back locating slot, with internal thread in described through hole, pilot pin with internal thread coupling is installed in described each through hole, described pilot pin length is greater than the degree of depth of through hole, the rear side of described pilot pin is furnished with nut.
