Specific embodiment
The utility model will be further described below with reference to the accompanying drawings, but the utility model is not subject in any way
Limitation based on any changes and modifications that the utility model training centre is made, belongs to the scope of protection of the utility model.
As shown in Fig. 1~2, the utility model includes upper mold seat 4, upper mold core 10, die holder 1 and lower mold core 2, the upper mold
The top that seat 4 is arranged on die holder 1 is machined with rectangular channel on the length direction on the die holder 1 along die holder 1, under
The both sides of the upper surface of die holder 1 are symmetrically arranged with 2 activity of lower mold core described in positioning column 3 and put on the length direction along die holder 1
It puts in rectangular channel and knob 17 is installed in the end of wherein one end of lower mold core 2, the upper surface of the lower mold core 2 is machined with
Hinge placing groove 12 is machined with and the corresponding location hole 5 of 3 quantity of positioning column and position, the upper mold core on the upper mold seat 4
10 are movably arranged on the lower surface of upper mold seat 4, and the shape and the shape of hinge placing groove 12 of the lower surface of the upper mold core 10 are matched
Setting is closed, the upper surface of the upper mold seat 4 is equipped with the driving mechanism 6 that driving upper mold seat 4 moves back and forth up and down, it is preferable that institute
Driving mechanism 6 is stated as hydraulic cylinder.
The utility model is when in use：The computer hinge of shaping is needed to be placed in the hinge placing groove 12 of lower mold core 2, so
Push knob 17 that can easily be pushed into lower mold core 2 in the rectangular channel of die holder 1 afterwards, lower mold core 2 pushes to suitable position
Afterwards, then by upper mold core 10 it being mounted on upper mold seat 4, starts driving machine 6 later, driving mechanism 6 drives upper mold seat 4 to move down,
After the location hole 5 on upper mold seat 4 is made to pass through the positioning column 3 on die holder 1, die holder 1 is allowed to be pressed on upper mold seat 4, at this point, sharp
Shaping can be carried out to the computer hinge in lower mold core 2 with the extruding force of upper mold core 10, the effect of the positioning column 3 is to
Accurate positioning to upper mold seat 4 and die holder 1 makes remaining in the same plane for upper mold seat 4 and die holder 1, avoids
It shifts, influences the precision of shaping, after shaping, driving mechanism 6 drives upper mold seat 4 to move up, and upper mold seat 4 returns to original
Position, then lower mold core 2 is pulled out by knob 17, the product after shaping is taken out, the product for needing shaping is relay, according to above-mentioned
Step carries out shaping.On the one hand the shaping tool of this structure has saved the set-up time of mold, can quickly realize
It mold core and die holder quick fixed and detaches, it is only necessary to Rational Change mold core, it is complete to can be realized as to various specifications and type
Product carries out shaping；On the other hand use drawer type mold core formula structure, it is not only once can simultaneously the multiple products of shaping, carry
High working efficiency, and product can be limited by upper mold core 10 and lower mold core 2, the extruding force for allowing upper mold core 10 is direct
Acting on product needs the position of shaping, so as to fulfill the accurate shaping to product.
In order to meet the shaping to the computer hinge of different structure, the rectangle trench bottom of the die holder 1 is under
The sliding slot 13 being recessed inwardly is symmetrily processed on the length direction of die holder 1, the bottom of the lower mold core 2 is machined with and 13 phase of sliding slot
