Abstract
A kind of positioning key of adjustable stock mould cavity dimension, comprise the location division I and location division II that are fixedly connected with, and be stuck in the locating slot of neighbouring stock mould template, stock mould die cavity is formed to make neighbouring stock mould template, described location division I is consistent with the width of location division II, and in the direction of the width, one end of location division I protrudes from the edge of location division II respective end, to form the adjustment end for adjusting cavity dimension.The utility model is arranged on after in the locating slot of neighbouring stock mould template respectively by location division I and location division II, two stock mould templates are made to produce relative displacement, thus the size of adjustment stock mould die cavity, do not need finishing template can adapt to the requirement of technique, structure is simple, easy to operate, with low cost.
Description
Technical field
The utility model relates to a kind of positioning key of adjustable size, especially relates to a kind of positioning key for adjusting stock mould cavity dimension in profiled bar extrusion die.
Background technology
Extrusion moulding special shapes stock mould is a part for extrusion moulding special shapes extrusion die, stock mould part is jointly formed by positioning key location and screw fastening by between each template, the die cavity surrounding of stock mould is processed with cooling water hole and vacuum hole, in normal productive process from mouth mould part type embryo out by stock mould cooling and shaping, then become qualified product through negative pressure of vacuum water tank cooling twice final production.In process of production because various different reason needs to carry out various finishing to cavity portion size, structure due to existing positioning key does not possess the effect of adjustment template die cavity, therefore the method increasing material or remove material in template is generally adopted to carry out, its process all more complicated, cost is high, expense is large, very high to the technical requirement that repairs a die, great destabilizing factor is in use brought to mould, such as layer comes off, and easily make template become defective, can not reuse.
Utility model content
For solving cavity dimension finishing problem, the purpose of this utility model is to provide a kind of positioning key of adjustable size, by the improvement of positioning key structure, do not need to repair the finishing that template can realize stock mould cavity dimension in profiled bar extrusion die, to adapt to the requirement of technique, structure is simple, easy to operate, with low cost.
For solving the problems of the technologies described above, the utility model by the following technical solutions:
A kind of positioning key of adjustable stock mould cavity dimension, comprise the location division I and location division II that are fixedly connected with, and be stuck in the locating slot of neighbouring stock mould template, stock mould die cavity is formed to make neighbouring stock mould template, described location division I is consistent with the width of location division II, and in the direction of the width, one end of location division I protrudes from the edge of location division II respective end, to form the adjustment end for adjusting cavity dimension, after in the locating slot that location division I and location division II are arranged on neighbouring stock mould template respectively, two stock mould templates are made to produce relative displacement, thus the size of adjustment stock mould die cavity.
The utility model compared with prior art, there is following beneficial effect: the utility model is when adjusting cavity dimension, only need according to size changing amount, common positioning key is changed into the positioning key in the utility model meeting size changing amount requirement, because in template, the width of locating slot is certain, therefore under the constraint of the utility model positioning key, between upper and lower stock mould, produce relative displacement, the object of adjustment stock mould cavity dimension can be reached.Whole adjustment process, does not need the character changing positioning key, does not adopt the way of welding or removal material to reach requirement to template yet, thus realize the object of whole stock mould cavity dimension adjustment, greatly simplifie operation, reduce production cost, extend the mold use life-span.

Detailed description of the invention
Below in conjunction with accompanying drawing, by specific embodiment, the utility model is further described.
As shown in Figure 2, a kind of positioning key of adjustable stock mould cavity dimension, comprise and be stuck in location division in neighbouring stock mould template 7 locating slot I 3 and location division II 4, location division I 3 is consistent with the width of location division II 4, and in the direction of the width, one end of location division I 3 protrudes from the edge of location division II 4 respective end, to form the adjustment end 5 for adjusting cavity dimension.
As shown in Figure 3, conventional positioning key 1 of the prior art is screwed between the neighbouring stock mould template 7 being arranged on profiled bar extrusion die 6, the cavity dimension that stock mould is surrounded reaches the 27.93mm of designing requirement, in process, when cavity dimension is adjusted to 27.63mm by needs, usually throat thickness on template interior plate 8 is needed to be that the workpiece of 0.3mm is to reach designing requirement in the prior art, this method operates very complicated, high cost, very high to the technical requirement that repairs a die, and in use bring great destabilizing factor to mould, such as layer comes off.
As shown in Figure 4, after the positioning key 2 being of a size of the adjustable stock mould cavity dimension of 0.3mm with adjustment part replaces conventional positioning key 1, one end due to location division I 3 forms adjustment end 5, make after in the locating slot that location division I 3 and location division II 4 are arranged on neighbouring stock mould template respectively, two stock mould templates 7 are made to produce relative displacement, therefore, stock mould interior plate 8 moves 0.3mm to the inside, cavity dimension is made to be corrected for 27.63mm, reach the size required by technique, and in this adjustment process, do not change the character of positioning key, also the way of welding or removal material is not adopted to reach requirement to template 7, finally complete the whole process of whole stock mould partly molding cavity size adjusting.
Claims (1)
1. the positioning key of an adjustable stock mould cavity dimension, comprise the location division I (3) and location division II (4) that are fixedly connected with, and be stuck in the locating slot of neighbouring stock mould template (7), stock mould die cavity is formed to make neighbouring stock mould template (7), it is characterized in that: described location division I (3) is consistent with the width of location division II (4), and in the direction of the width, one end of location division I (3) protrudes from the edge of location division II (4) respective end, to form the adjustment end (5) for adjusting cavity dimension, after in the locating slot that location division I (3) and location division II (4) are arranged on neighbouring stock mould template (7) respectively, two stock mould templates (7) are made to produce relative displacement, thus the size of adjustment stock mould die cavity.
