Specific embodiment
To further illustrate the technical scheme of the present invention below with reference to the accompanying drawings and specific embodiments.
It is as shown in Figure 1 the robot leg sliding block made of mold, as seen in Figure 1, the robot leg
Sliding block is formed by connecting by multiple components, and has multiple curved-surface structures, and structure is more complicated, is illustrated in figure 2 the prior art
In the die cut view for robot leg sliding block, due to this for robot leg sliding block mold not in master mold
400 and male model 500 on set up special location structure, therefore when embryo material is processed into robot leg sliding block finished product, male model 500
It misplaces frequent occurrence with master mold 400, leads to seam out-of-flatness at parting, be easy to appear segment difference, in the situation that sliding block glue position is larger
Under, flash situation is serious at parting, is not easy to improve, and it is low using robot leg sliding block finished product accuracy made of the mold, it is whole
Intensity is low, is not able to satisfy production needs.
As shown in Figures 3 to 6, the mold of robot leg sliding block, including 1 He of master mold are used for provided in the present embodiment
Male model 2 is fixedly installed upper cores 3 inside master mold 1, and lower mode 6, upper cores 3 and lower mode 6 are fixedly installed in male model 2
Between slide core 4 has been fixedly mounted, as shown in figure 3, slide core 4 is fixed on using 40Cr or 45 Jing Guo modulation treatment
On wedge block 5 made of number steel and just opposite with the lozenges of wedge block 5, the upper surface of slide core 4 is and upper cores 3
The mutually stitching surface of pressing, is provided with standard station 402, the bottom surface of standard station 402 is bonded with stitching surface, standard station on the stitching surface
Wedge locating block 401 is provided on 402 top surface, the bottom surface of wedge locating block 401 is bonded with the top surface of standard station 402, wedge shape
Lozenges and the vertical plane just opposite with the lozenges and 3 slide guide of upper cores on locating piece 401, which match to merge, constitutes positioning surface, wedge
The angle of the lozenges of shape locating piece 401 be greater than wedge block 5 on lozenges angle, differential seat angle preferably within 30 degree,
Such a differential seat angle successively removes wedge block 5 and slide core 4 convenient for positioning and dividing when mould, remote on standard station 402
Facade from lozenges on wedge locating block 401, with composition datum level is merged, is arranged useful with 3 slide guide of upper cores in upper cores 3
In the locating slot 301 of positioning wedge locating block 401,301 cavity shape of locating slot is identical as 401 shape of wedge locating block, size
It is slightly larger, in order to the disengaging of wedge locating block 401.
In use, master mold 1 is buckled on male model 2, and the space for accommodating blank is formed between upper cores 3 and lower mode 6,
Under the effect of external force, robot leg sliding block as shown in Figure 1 is made in embryo material deformation, due to being provided in slide core 4
Wedge locating block 401,3 slide guide of lozenges and the vertical plane just opposite with the lozenges and upper cores on wedge locating block 401
Constitute positioning surface with merging, efficiently located slide core 4 and upper cores 3, it is therefore prevented that male model 2 and master mold 1 occur dislocation and
Occur segment difference at parting, improve the efficiency with mould during mold assembling significantly, has saved with the time needed for mould, improved
The quality of product finished product, precision and stability.
In order to promote locating effect, the process screw hole of auxiliary positioning is provided on wedge block 5 and upper cores 3
302, in addition to this, the globality of wedge block 5 and upper cores 3 can be improved in process screw hole 302, makes electric discharge, processing, polishing
Can be carried out with portion with techniques such as textures, the number in process screw hole 302 be it is multiple, rectangular array is arranged in wedge block 5
In upper cores 3, in the present embodiment, the diameter in process screw hole 302 is M8, the process screw hole 302 on wedge block 5
Number is four, and in the column arrangement of two rows two, the number in the process screw hole 302 in upper cores 3 is similarly four, is arranged in two rows two
Arrangement.
In order to improve the processing efficiency of robot leg sliding block, two upper cores being arranged symmetrically are provided in master mold 1
3, it is equally symmetrically arranged with the lower mode 6 being used cooperatively with upper cores 3 in male model 2, can be produced simultaneously by once molding
Two robot leg sliding blocks, improve the utilization rate of mold.
Obviously, the above embodiment of the present invention is just for the sake of clearly illustrating examples made by the present invention, and being not is pair
The restriction of embodiments of the present invention.For those of ordinary skill in the art, may be used also on the basis of the above description
To make other variations or changes in different ways.There is no necessity and possibility to exhaust all the enbodiments.It is all this
Made any modifications, equivalent replacements, and improvements etc., should be included in the claims in the present invention within the spirit and principle of invention
Protection scope within.
