Abstract
The invention relates to a punching die of a deadening felt, which comprises an upper die set and a lower die set. A die cavity is disposed between the upper die set and the lower die set. The punching die of the deadening felt further comprises a leftover material punching assembly which is distributed around the die cavity. Compared with the prior art, the punching die of the deadening felt has the advantages of low development cost, short period and the like.
Description
Technical field
The present invention relates to a kind of die cutting die, especially relate to a kind of die cutting die of deadening felt.
Background technology
The die cutting die of felt is divided into two kinds of moulds at present, and a kind of is the male and female die cutting dies; Another kind is to chop mould, and the operation principle of male and female die cutting die is: the semi-finished product felt part of forming is sheared, and the operation principle of chopping mould is, thereby making it to rupture through edge of a knife extruding felt material reaches the purpose that cuts the part leftover pieces.We are not difficult to find out that the product periphery quality that the male and female die cutting die makes will get well from operation principle, but development cost is big, and the construction cycle is long, operation and maintenance cost height.And chop mould, the product periphery of making is of poor quality, and chops mould individual distinct disadvantage is arranged, edge of a knife rapid wear, often maintaining mould.
Summary of the invention
The object of the invention is exactly the die cutting die that the deadening felt that a kind of development cost is low, the cycle is short is provided for the defective that overcomes above-mentioned prior art existence.
The object of the invention can be realized through following technical scheme:
A kind of die cutting die of deadening felt comprises top mold frame, following mould bases, described top mold frame, is provided with mold cavity between the mould bases down, it is characterized in that, also comprises the die-cut assembly of leftover pieces, the die-cut assembly of these leftover pieces be distributed in mold cavity around.
The die-cut assembly of described leftover pieces comprises that serrated knife, sawtooth tool rest, heating resistor, heat insulating mattress, polyurethane goes into edge bearing; Described serrated knife one end is fixed on the sawtooth tool rest, and when matched moulds, the described serrated knife other end inserts polyurethane and goes in the edge bearing; Described sawtooth tool rest is fixedly connected with top mold frame through heat insulating mattress; Described polyurethane is gone into edge bearing and is fixed on down on the mould bases, and described heating resistor is contained on the sawtooth tool rest, and is connected with serrated knife.
Compared with prior art, the present invention has the following advantages:
1, through heating resistor serrated knife is heated, let die-cut neat more agile of product periphery, and stop under the heat through heat insulating mattress and to pass to die ontology, prevent to cause energy waste and other damages of avoiding bringing to mould because of generating heat;
2, increase the service life of polyurethane; Because melting, the heated serrated knife of fiber has no progeny; Just do not go into edge bearing putting into polyurethane, the serrated knife of the heating plasticity of also having accelerated the shape of polyurethane is recovered simultaneously, and equally also being has increased the service life that polyurethane is gone into edge bearing;
3, development cost is low, and the cycle is short;
4, can be applied to the automotive sound-proof felt mould, in the moulds such as car carpeting mould, automobile panel, have good market prospects.
Description of drawings
Fig. 1 is a structural representation of the present invention;
Fig. 2 is the A portion enlarged drawing of Fig. 1.
The specific embodiment
Below in conjunction with accompanying drawing and specific embodiment the present invention is elaborated.
Embodiment
As shown in Figure 1, a kind of die cutting die of deadening felt comprises top mold frame 1, following mould bases 2, described top mold frame, is provided with mold cavity between the mould bases down, also comprises the die-cut assembly of leftover pieces, the die-cut assembly of these leftover pieces be distributed in mold cavity around.
As shown in Figure 2, the die-cut assembly of described leftover pieces comprises that serrated knife 6, sawtooth tool rest 4, heating resistor 5, heat insulating mattress 3, polyurethane goes into edge bearing 7, and described serrated knife 6 one ends are fixed on the sawtooth tool rest 4; When matched moulds; Described serrated knife 6 other ends insert polyurethane goes in the edge bearing 7, and described sawtooth tool rest 4 is fixedly connected with top mold frame 1 through heat insulating mattress 3, and described polyurethane is gone into edge bearing 7 and is fixed on down on the mould bases 2; Described heating resistor 5 is contained on the sawtooth tool rest 4, and is connected with serrated knife 6.
Operation principle is following:
The half-finished parts of forming is put into mold cavity, accomplish the location after, the opening mold matched moulds, go into edge bearing 7 through sawtooth blade 6 incision polyurethane after, cut off the leftover pieces of product, accomplish the purpose of die-cut part.Can reach the general requirement of die cutting die in fact like this; The effect of heating resistor 5 is that the energising back is heated to certain suitable temperature to serrated knife 6; The effect of heat insulating mattress 3 is to stop under the heat to pass to die ontology, other damages that cause energy waste and avoid bringing to mould because of heating.
The effect of serrated knife 6 heating is following:
The one, let die-cut neat more agile of product periphery, (because the fiber of the part of most of felt all is more weak and long, so not die-cut to certain temperature of serrated knife heated blade, the part of going out is peripheral to be compared mao);
The 2nd,, increase service life of polyurethane; Because melting, the heated serrated knife of fiber has no progeny; Just do not go into edge bearing putting into polyurethane, the serrated knife of the heating plasticity of also having accelerated the shape of polyurethane is recovered simultaneously, and equally also being has increased the service life that polyurethane is gone into edge bearing.
Claims (2)
1. the die cutting die of a deadening felt comprises top mold frame, mould bases down, described top mold frame, is provided with mold cavity between the mould bases down, it is characterized in that, also comprises the die-cut assembly of leftover pieces, the die-cut assembly of these leftover pieces be distributed in mold cavity around.
2. the die cutting die of a kind of deadening felt according to claim 1; It is characterized in that the die-cut assembly of described leftover pieces comprises that serrated knife, sawtooth tool rest, heating resistor, heat insulating mattress, polyurethane goes into edge bearing, described serrated knife one end is fixed on the sawtooth tool rest; When matched moulds; The described serrated knife other end inserts polyurethane goes in the edge bearing, and described sawtooth tool rest is fixedly connected with top mold frame through heat insulating mattress, and described polyurethane is gone into edge bearing and is fixed on down on the mould bases; Described heating resistor is contained on the sawtooth tool rest, and is connected with serrated knife.
