Abstract
The invention relates to a felt punching die which is composed of an upper die frame and a lower die frame. After the upper die frame and the lower die frame are closed, a die cavity used for containing semi-finished parts is formed between the upper die frame and the lower die frame, the periphery of the die closing surface of the upper die frame and the lower die frame is provided with a jagged blade used for cutting the semi-finished parts, and the jagged blade is connected to the upper die frame through a tool holder; the tool holder is connected with a heating resistor and a thermal insulation pad, and a blade-in pad matched with the jagged blade is arranged on the periphery of the die closing surface of the lower die frame and the upper die frame. Compared with the prior art, according to the felt punching die, by heating the jagged blade, punching of the peripheries of the semi-finished parts can be more tidy and neat; in addition, punching can be completed only needing to add one heating resistor; the cost is low, convenience is achieved, and the service life of the blade-in pad can be prolonged.
Description
Technical field
The present invention relates to a kind of mould, especially relate to a kind of die cutting die of felt.
Background technology
The die cutting die of current felt is important is divided into two kinds of moulds, and one is male and female die cutting dies; One chops mould, and the operation principle of male and female mould is: sheared by the semi-finished product felt part of forming, the operation principle chopping mould is, made it fracture by edge of a knife extruding felt material thus reached the object cutting part leftover pieces.Be not difficult to find out that the product periphery quality that die cutting die is made will be got well from operation principle, but development cost is large, the construction cycle is long, and operation and maintenance cost is high.And it is of poor quality to chop the product periphery that mould makes, and chops mould and have individual distinct disadvantage, edge of a knife rapid wear, must frequent maintaining mould.How to solve the problem is a difficult problem urgently to be resolved hurrily at present.
Summary of the invention
Object of the present invention is exactly provide a kind of more neat agile, the die cutting die that increases the felt in service life that make half-finished parts periphery die-cut to overcome defect that above-mentioned prior art exists.
Object of the present invention can be achieved through the following technical solutions:
A die cutting die for felt, is made up of top mold frame and lower mold holder, forms the mold cavity placing half-finished parts in the middle of after top mold frame and lower mold holder matched moulds,
The surrounding of described top mold frame and lower mold holder land area is provided with sawtooth blade for cutting half-finished parts,
Described sawtooth blade is connected in top mold frame through tool rest, this tool rest is connected with heating resistor and heat insulating mattress,
The surrounding of described lower mold holder and top mold frame land area be provided with match with sawtooth blade enter edge bearing.
Described tool rest is coated on the outside of sawtooth blade.
Described heating resistor is located at the outside of tool rest, and heat sawtooth blade through tool rest conduction, heating-up temperature is determined according to the material of die-cut felt, is in general heated to 70 DEG C-90 DEG C.
By heating sawtooth blade, can allow die-cut more neat agile of half-finished parts periphery, because the fiber of the part of most of felt is all more weak and long, therefore not die-cut to certain temperature of serrated knife heated blade, the part periphery gone out compares hair; The service life of polyurethane can also be increased in addition, have no progeny because fiber is melted by the serrated knife heated, just do not enter in edge bearing at plug at polyurethane, the plasticity that the serrated knife simultaneously heated also accelerates the shape of polyurethane is recovered, and is equally also the increase in the service life that polyurethane enters edge bearing.
Described heat insulating mattress is arranged on the junction of tool rest and top mold frame, stops heat conduction on mould bases, thus avoid causing energy waste and bring to mould because of heating other damage.
The described edge bearing that enters is that polyurethane enters edge bearing.
Compared with prior art, the present invention has the following advantages:
One, because the fiber of the part of most of felt is all more weak and long, therefore not die-cut to certain temperature of serrated knife heated blade words, the part periphery gone out compares hair, therefore by heating sawtooth blade, can allow die-cut more neat agile of half-finished parts periphery, only need increase heating resistor namely can complete in addition, cost is lower and more convenient;
Two, the service life of polyurethane can also be increased, have no progeny because fiber is melted by the serrated knife heated, just do not enter in edge bearing at plug at polyurethane, the plasticity that the serrated knife simultaneously heated also accelerates the shape of polyurethane is recovered, and is equally also the increase in the service life that polyurethane enters edge bearing;
Three, requirement on machining accuracy is not high, and lower than the machining accuracy of male and female die cutting die is many, has development cost low, the feature that the cycle is short.
Four, the present invention can be applied to automotive sound-proof felt mould, in the moulds such as car carpeting mould, automobile panel, has good market prospects.
Accompanying drawing explanation
Fig. 1 is structural representation of the present invention;
Fig. 2 is the close-up schematic view in Fig. 1.
In figure, 1 for top mold frame, 2 for lower mold holder, 3 for heat insulating mattress, 4 for tool rest, 5 for heating resistor, 6 for sawtooth blade, 7 for entering edge bearing.
Detailed description of the invention
Below in conjunction with the drawings and specific embodiments, the present invention is described in detail.
Embodiment
A die cutting die for felt, its structure as shown in Figure 1-2, forms primarily of top mold frame 1 and lower mold holder 2, forms the mold cavity placing half-finished parts in the middle of after top mold frame 1 and the 2-in-1 mould of lower mold holder.Sawtooth blade 6 is provided with for cutting half-finished parts in top mold frame 1 and the surrounding of the 2-in-1 die face of lower mold holder, this sawtooth blade 6 is connected in top mold frame 1 through tool rest 4, tool rest 4 is connected with heating resistor 5 and heat insulating mattress 3, wherein, tool rest 4 is coated on the outside of sawtooth blade 6, and heating resistor 5 is located at the outside of tool rest 4, conducts heat sawtooth blade 6 through tool rest 4, temperature is determined according to the material of die-cut felt, and the present embodiment is heated to 70 DEG C-90 DEG C.Heat insulating mattress 3 is arranged on the junction of tool rest 4 and top mold frame 1, and what lower mold holder 2 and the surrounding of top mold frame 1 land area were provided with the polyurethane material matched with sawtooth blade 6 enters edge bearing 7.
By heating sawtooth blade 6, allow die-cut more neat agile of half-finished parts periphery, because the fiber of the part of most of felt is all more weak and grows, thus not die-cut to certain temperature of serrated knife heated blade, the part periphery gone out compares hair; The service life entering edge bearing 7 of polyurethane material can also be increased in addition, have no progeny because fiber is melted by the serrated knife heated, just do not enter in edge bearing 7 at plug in polyurethane material, the plasticity that the sawtooth blade 6 simultaneously heated also accelerates the shape of polyurethane is recovered, and is equally also the increase in the service life entering edge bearing 7 of polyurethane material.Heat insulating mattress 3 can stop heat conduction on mould bases, thus avoid causing energy waste and bring to mould because of heating other damage.
