Abstract
The invention provides a cutting die for die-cutting a rubber foot pad and belongs to the field of die-cutting parts. The cutting die comprises a die carrier and a cutter, wherein the cutter is arranged on the die carrier and extends upward from the upper surface of the die carrier, and the cutting edge of the cutter faces upward; the upper surface of the die carrier is provided with threaded through holes which are distributed in a rectangular array mode, and the die carrier is connected with a bolt by virtue of the threaded through holes; the bolt penetrates through the threaded through holes; the head of the bolt is clamped at the lower surface of the die carrier; the other end surface of a stud is parallel to the lower surface of the die carrier; the cutter is fixedly arranged on the stud of the bolt; the upper surface of the die carrier is connected with a spring; the other end of the spring is connected with a movable die carrier; the shape of the spring corresponds to that of the die carrier, and the spring is provided with a through hole which corresponds to the cutter. The cutting die has the advantages that the cutter can be replaced conveniently by virtue of the arranged bolt, so that resources are saved; furthermore, due to the existence of the movable die carrier, the through holes are firstly contacted with a material, so that the position of the material is adjusted the centering condition of die cutting is good.
Description
Technical field
The present invention relates to the die-cut part of rubber, refer more particularly to a kind of cutting die for die-cutting rubber foot pad.
Background technology
Rubber industry is one of important foundation industry of national economy, the light industry rubber product such as daily, medical that it provides daily life indispensable for people, rubber mat good looking appearance in rubber, there is effect that is anti-skidding, crashproof, shockproof, anti-scratch, along with the growth in the living standard of people, rubber mat has been common in each large top-grade furniture, showing stand, electronic product, handicraft etc.
Many household electrical appliance play a supportive role as electric cooker or notebook computer etc. are all provided with rubber mat on four of bottom angles, this rubber mat is generally many with circular globoidal structure, its manufacturing process is as follows: the multi-cave mould moulded rubber substrate by die cavity being first circular globoidal structure, namely rubber substrate has the rubber mat of multiple circular globoidal structure, adopt the cutting die identical with the geomery of rubber mat to carry out die-cut to on-chip foot pad, independently many rubber mat finished products can be obtained.Existing cutting die for die-cutting rubber foot pad comprises mould bases and cutter, the shape of cutter is offered according to the geomery correspondence of foot pad, and cutter and mould bases are the metalworks integrally made, once there be a damage in the multiple cutters on mould bases, whole cutter and mould bases all will be changed, and greatly waste resource.In addition, when foot pad die-cut with cutting die, sometimes because the slight shift of cutter and foot pad, the foot pad finished product of die-cut gained can be caused to have boss or scarce limit, affect the quality of product.
Through retrieval, China Patent No.: ZL201020670838.9, authorized announcement date: on August 10th, 2011, denomination of invention is: a kind of cutting die for die-cutting rubber foot pad, comprise mould bases, be arranged on mould bases and upwards extend from the surface of mould bases and edge of a knife cutter upward, the shape of cutter is offered according to the shape correspondence of rubber mat, and the knife back activity of cutter is embedded in mould bases, and in mould bases, can move horizontally certain limit to all directions.In this application case, during the die-cut rubber mat of cutting die, cutter by moving horizontally adjustment self-position and having certain flexible rubber mat corresponding matching voluntarily, can cause the rubber mat finished product of die-cut gained substantially without boss or scarce limit, the qualification rate of improving product.But because flush shear force is large, speed is high, rely on cutter can move horizontally adjustment self-position and have certain flexible rubber mat effect of corresponding matching not obvious voluntarily, and, cutter can not be changed, once there be a damage in multiple cutters on mould bases, whole cutter and mould bases all will be changed, and are also waste the one of resource.
Summary of the invention
Technical problem to be solved by this invention is to provide a kind of cutting die for die-cutting rubber foot pad, once have a rear whole cutter of damage and mould bases all will change in the multiple cutters in solution prior art on mould bases, wastes resource; And the slight shift of cutter and foot pad, the foot pad finished product of die-cut gained can be caused to have boss or scarce limit, affect the problem of product quality.
For solving the problems of the technologies described above, a kind of cutting die for die-cutting rubber foot pad of the present invention, comprise mould bases and be arranged on also surperficial from it on mould bases upwards extension and edge of a knife cutter upward, wherein, described mould bases upper surface is provided with tapped through hole, rectangular array distribution, bolt is connected with by screwed hole, described bolt-through tapped through hole, bolt head is stuck in the lower surface of described mould bases, the other end of stud is parallel with the lower surface of described mould bases, and described cutter is fixedly installed on the stud of bolt; Described mould bases upper surface is connected with spring, and the described spring other end is connected with movable mould bases, and described movable mould bases shape is corresponding with mould bases, and is provided with the through hole corresponding with cutter.
Further, the upper surface 1 ~ 10mm higher than the edge height of cutter of described movable mould bases.
Further, the openings of the upper surface of described movable mould bases is provided with rounding, and rounding radii is 0.5 ~ 2mm.
Adopt technical scheme provided by the invention, compared with existing known technology, there is following beneficial effect:
(1) a kind of cutting die for die-cutting rubber foot pad of the present invention, when occurring when there being cutter damaging, by the bolt arranged, makes cutter changing convenient, saving resource.
(2) a kind of cutting die for die-cutting rubber foot pad of the present invention, due to the existence of movable mould bases, time die-cut, the through hole on movable mould bases first contacts with rubber substrate, and adjustment positions of materials, die-cut is good to conditional, can prevent the appearance of boss or scarce limit problem.
(3) a kind of cutting die for die-cutting rubber foot pad of the present invention, structure is simple, is easy to manufacture, low production cost.
