Abstract

A kind of die cutting die with tooth form that the utility model relates to a kind of can thoroughly to thrust the plastic film of overlay film lid in Easy tearing lid production line, including punching cavity plate and punching punch-pin, the upper surface of the punching cavity plate or the lower surface for being punched punch-pin are toothed surface；Or the upper surface of punching cavity plate and the lower surface of punching punch-pin are toothed surface.Advantage: not only solving the continuous phenomenon of coupling silk existing for background die cutting die punching plastic film, and blanking pressure needed for reducing die cutting die, saves energy consumption.

Description

A kind of die cutting die with tooth form

Technical field

The utility model relates to a kind of can thoroughly to thrust the plastic film of overlay film lid in Easy tearing lid production line A kind of die cutting die with tooth form belongs to Easy tearing lid die cutting die manufacturing field.

Background technique

For being punched the die cutting die of plastic film in structure design in existing Easy tearing lid production line, die cutting die The upper surface of cavity plate and the lower surface of punching punch-pin are plane die cutting die, and blanking pressure is big, but when being punched plastic film, by In plastic film there is good toughness to be not easy thoroughly to thrust film, it is often separated but still in each other's thoughts.

The utility model solves the problems, such as to reduce blanking pressure very well and is punched plastic film.

Summary of the invention

Purpose of design: avoiding the shortcoming in background technique, design one kind in Easy tearing lid production line can thoroughly by A kind of die cutting die with tooth form that the plastic film of overlay film lid is thrust.

Design scheme: in order to realize above-mentioned purpose of design.The utility model is on the basis of background technique, by existing punching It cuts the upper surface for being punched cavity plate in mould or is designed to tooth-shape structure, or the upper surface that cavity plate will be punched on the lower surface for being punched punch-pin Toothed surface structure is designed to on the lower surface of punching punch-pin, the purpose of this design is: institute's communications centre in Easy tearing lid production line Film is cut in punching, when plastic film is punched by toothed surface die cutting die, die cutting die is punched the toothed surface of mouth for institute It is punched film and is divided into multiple punching faces, at this time when die cutting die is punched plastic film, plastic film is in mold toothed surface It is easy to be cut off under effect, to fundamentally not only solve the defect of background technique, and reduces blanking pressure.

Technical solution: a kind of die cutting die with tooth form, including punching cavity plate and punching punch-pin, it is described to be punched the upper of cavity plate Surface or the lower surface for being punched punch-pin are toothed surface；Or the upper surface of punching cavity plate and the lower surface of punching punch-pin are toothed surface.

The utility model compared with the background art, not only solves coupling silk existing for background die cutting die punching plastic film Continuous phenomenon, and blanking pressure needed for reducing die cutting die, save energy consumption.

Specific embodiment

Embodiment 1: referring to attached drawing 1-7.A kind of die cutting die with tooth form, including punching cavity plate 2 and punching punch-pin 1, institute The upper surface D for the stating punching cavity plate 2 or lower surface C for being punched punch-pin 1 is toothed surface；Or it is punched the upper surface D of cavity plate 2 and is punched convex The lower surface C of mould 1 is toothed surface.The tooth form quantity is greater than two, and the distribution of tooth form radially distributes or non-radioactive shape Distribution.The depth of profile is greater than 0.02mm, is less than 2mm.The section of the tooth form is sharp tooth or non-sharp tooth.

Embodiment 2: it on the basis of embodiment 1, is arbitrarily taken in the depth of profile most preferably 0.05-1mm value range It is worth and including end value.

It should be understood that being: although above-described embodiment has made detailed verbal description to the utility model mentality of designing, But the description of these texts, only the simple text of the utility model mentality of designing is described, rather than to the utility model The limitation of mentality of designing, any combination, increase or modification without departing from the utility model mentality of designing, each falls within the utility model Protection scope in.
