Abstract
The utility model discloses a punch die structure capable of preventing a product from showing a bottom color. The punch die structure capable of preventing the product from showing the bottom color comprises an upper die core and a lower die core, wherein the upper die core is matched with the lower die core to form a die body. The punch die structure capable of preventing the product from showing the bottom color is characterized in that tool edges which are meshed with each other are arranged on the periphery of the upper die core and the periphery of the lower die core respectively, and the outer side of the tool edge of the upper die core extends downward in the direction of the lower die core to form an extension portion. According to the punch die structure capable of preventing the product from showing the bottom color, due to the adoption of the extension portion, composite boards are cut after being basically formed through extrusion and pre-stretching, and the phenomenon that the bottom color of the product is shown after the product edge is abraded by the tool edges is avoided.
Description
Technical field
The utility model relates to the production mould, relates in particular to a kind of die cutting die structure of avoiding product to show money or valuables one carries unintentionally.
Background technology
The materials such as vehicle interior ceiling adopt composite panels such as also having nonwoven, glass mat to make, and wherein, the tensile property of nonwoven is poor.
When this composite is carried out punching press, moulding, at first composite is carried out infrared heating, then carry out moulding, die-cut.In die-cut process, composite directly contacts with the edge of a knife, produces friction, thereby makes the material cutting have larger sequencing, and simultaneously, the tensile property of nonwoven is poor, easily causes product to show money or valuables one carries unintentionally.
The utility model content
The purpose of this utility model is to overcome above deficiency, and a kind of die cutting die structure of avoiding product to show money or valuables one carries unintentionally is provided.
The die cutting die structure that product shows money or valuables one carries unintentionally of avoiding that the utility model provides comprises: upper cores and lower die, upper cores, lower die cooperatively interact, form die ontology, it is characterized in that, upper cores and lower die periphery are provided with the intermeshing edge of a knife, and under upper cores edge of a knife lateral, the die direction is extended with extension section.Thus, before die-cut, the outer edge of composite, at first through extruding, prestretched, is cut after making composite draw thin, basic forming again, prevent from that product and the edge of a knife from directly contacting to produce to rub, the phenomenon that shows money or valuables one carries unintentionally occurs.
In some embodiments, the upper edge of a knife of upper cores is positioned at the lower edge of a knife outside of lower die, and the upper edge of a knife and the lower edge of a knife are vertical and tangent.Thus, the effect of pressure to, the upper edge of a knife and the lower edge of a knife cooperatively interact, and realize cutting.
In some embodiments, extension section is positioned at the periphery of the edge of a knife, and plane, extension section place, lower than the plane at the edge of a knife place of upper cores, is provided with gap between extension section and the upper edge of a knife.Thus, product is well stretched.
In some embodiments, the distance in gap is 1-1.5mm.Thus, guarantee that product does not namely show money or valuables one carries unintentionally, also not there will be remaining limit.
In some embodiments, the height of extension section is 5-8mm.Thus, guarantee die-cutly front product fully to be pushed prestretched, improved drawing effect.
The die cutting die structure that product shows money or valuables one carries unintentionally of avoiding of the present utility model compared with prior art has the following advantages:
The die cutting die structure of avoiding product to show money or valuables one carries unintentionally of the present utility model,, by adopting extension section, allow composite board first through the extruding prestretched, substantially realize moulding, and then just cutting, avoided product along with edge of a knife friction, producing the phenomenon that shows money or valuables one carries unintentionally.
Description of drawings
Fig. 1 is the cutaway view of avoiding the die cutting die structure that product shows money or valuables one carries unintentionally of a kind of embodiment of the utility model.
Fig. 2 is the structural representation of avoiding A part in die cutting die structure that product shows money or valuables one carries unintentionally shown in Figure 1.
The specific embodiment
, in order to deepen understanding of the present utility model, below in conjunction with embodiment and accompanying drawing, to of the present utility model, avoid the die cutting die structure that product shows money or valuables one carries unintentionally to be described in further detail.
Fig. 1 and Fig. 2 have schematically shown the die cutting die structure of avoiding product to show money or valuables one carries unintentionally according to a kind of embodiment of the present utility model, and this embodiment only is used for explaining the utility model, does not form the restriction to the utility model protection domain.
As shown in the figure, the compound ejection die of die-cut acanthopore of the present utility model comprises: upper cores 10 and lower die 20, and upper cores 10, lower die 20 cooperatively interact, and form die ontology 1, and wherein, upper cores 10 and lower die 20 peripheries are provided with the intermeshing edge of a knife 30.
As shown in the figure, the upper edge of a knife 301 of upper cores 10 is positioned at the lower edge of a knife 302 outsides of lower die 20, and the upper edge of a knife 301 and the lower edge of a knife 302 are vertical and tangent.Under upper cores 10 edge of a knife laterals, die 20 directions are extended with extension section 40, and extension section 40 is positioned at the periphery of the edge of a knife 301, and extension section 40 planes, place are lower than the plane at the edge of a knife place of upper cores 10.The height of extension section 40 is 5-8mm, and in this embodiment of the present utility model, the height of extension section 40 is made as 6mm, guarantees die-cutly front product fully to be pushed prestretched, has improved drawing effect.301, extension section 40 and the upper edge of a knife are provided with gap 4301, and the distance in gap is 1-1.5mm, and in this embodiment of the present utility model, the distance in gap is made as 1.2mm,, to guarantee that product does not namely show money or valuables one carries unintentionally, also not there will be remaining limit.
When die cutting die uses, to composite board after infrared heating, then by containing the die cutting die of the die cutting die structure that product shows money or valuables one carries unintentionally of avoiding of the present utility model, carry out molding press cutting.The die cutting die structure of avoiding product to show money or valuables one carries unintentionally of the present utility model,, by adopting extension section, allow composite board first through the extruding prestretched, substantially realize moulding, and then just cutting, avoided product along with edge of a knife friction, producing the phenomenon that shows money or valuables one carries unintentionally.
