The utility model is characterized in that the upper die is provided with two rows of colliding hole deep drawing needles, piece falling needles and tearing needles; the spacing of corresponding adjacent two needles of the two rows of colliding hole deep drawing needles, piece falling needles and tearing needles is identical; the lower die is provided with colliding hole deep drawing needle holes, piece falling needle holes and tearing needle holes, which are corresponding to the two rows of colliding hole deep drawing needles, piece falling needles and tearing needles. The utility model has the advantages of high productive efficiency and low cost at the time of producing corns.

Description

A kind of Corn die

Technical field:

The utility model relates to a kind of mould, particularly a kind of mould of producing the stationery accessory.

Background technology:

The mould of existing production corn is that a mould once can only be produced a corn.This mould production efficiency is low, the production cost height.

Goal of the invention of the present utility model is to provide the corn mould of a kind of production efficiency height, low cost of manufacture.

The utility model is to realize like this, comprise mold, bed die, its special feature is that two row that mold is provided with side by side hit hole pull and stretch pin, the part pin that falls, tear pin, two row hit hole pull and stretch pin, the part pin that falls, the spacing of tearing corresponding adjacent two pins of pin are identical, and bed die is provided with two row and hits hole pull and stretch pin, the part pin that falls, tear at what answer and hit hole pull and stretch pin hole, the part pin hole that falls, tear pin hole.During work, stock metal plate is imported the bed die porch, start under the mold and dash, whenever after dashing, station of pulling stock metal plate reach, and then dash under the startup mold, like this, progressively stock metal plate is struck out each corn, last, by tearing pin the corn punching press of moulding is separated.

Here, for when the punching press securely with the stock metal plate positioning and fixing, on bed die, be provided with stock guide and holding pad, correspondence is hit hole pull and stretch pin hole, the part pin hole that falls, is torn pin hole and be provided with guide hole on stock guide, the holding pad.During work, mold presses down, and by stock guide, holding pad stock metal plate is compressed, and simultaneously, two row hit hole pull and stretch pin, the part pin that falls, tear pin and pass corresponding guide hole stock metal plate is carried out punching press, pull and stretch, the part that falls, torn.

Stock metal plate reach for convenience, holding pad can be gone up bullet, is provided with the Drawing Die that can the go up bullet bar that inclines below bed die.During work, after mold is finished a punching press, on move, holding pad also moves on immediately, and the Drawing Die bar that inclines is also gone up the top, with stock metal plate jack-up, hinder moving of stock metal plate with the part of avoiding being stamped recessed on the stock metal plate, the punch forming of corn can be finished smoothly.

Here, be provided with the location bobbin on mold, the bed die of corresponding location bobbin is provided with locating hole, and stock guide, the holding pad of corresponding location bobbin are provided with guide hole.Here, the location bobbin is arranged between two adjacent pull and stretch pins of every row.

Maintenance is for convenience hit hole pull and stretch pin hole, the part pin hole that falls, is torn pin hole and be arranged on respectively on the corresponding cylinder steel inserts, then cylinder steel inserts is fixed on the bed die to form on the corresponding position.Like this, when hit hole pull and stretch pin hole individually, the part pin hole that falls, when tearing pin hole and damaging, only need corresponding cylinder steel inserts is taken out, change first-class cylinder steel inserts and just can continue processing corn, keep in repair and mould need not be taken off, only need cylinder steel inserts to the damage that disassembles to keep in repair and get final product, thereby saved maintenance time.

Compared with the prior art the utility model owing to adopted a mould, produces the structural design of two corns simultaneously, therefore, and production efficiency height, advantage of low manufacturing cost when having the corn of production.

Description of drawings:

Fig. 1 is a structural representation of the present utility model;

Fig. 2 is the upward view of Fig. 1 mold;

Fig. 3 is the vertical view of Fig. 1 bed die;

Fig. 4 is the product stock layout figure in the corn process.

The specific embodiment:

Now in conjunction with the accompanying drawings and embodiments the utility model is described in further detail:

As shown in the figure, the utility model comprises mold 1, bed die 2, its special feature is that two row that mold 1 is provided with side by side hit hole pull and stretch pin 3, part pin 4 falls, tear pin 5, hit hole pull and stretch pin 3 and have 10, hit hole pull and stretch pin 3 length from short to long, part pin 4 falls, tear respectively one on pin 5, two row hit hole pull and stretch pin 3, part pin 4 falls, the spacing of tearing pin 5 corresponding adjacent two pins is identical, bed die 2 is provided with two row and hits hole pull and stretch pin 3, part pin 4 falls, that tears pin 5 correspondences hits hole pull and stretch pin hole 6, part pin hole 7 falls, tear pin hole 8, on bed die 2, be provided with stock guide 9 and the holding pad 10 that can go up bullet, stock guide 9, correspondence is hit hole pull and stretch pin hole 6 on the holding pad 10, part pin hole 7 falls, tear pin hole 8 and be provided with the guide hole that runs through, below bed die 2, be provided with the Drawing Die that can the go up bullet bar 11 that inclines, on mold 1 the 6th hits hole pull and stretch pin and rises every one and hit hole pull and stretch pin 3 or the part pin 4 or tear pin 5 and be equipped with location bobbin 13 of falling, the bed die 2 of corresponding location bobbin 13 is provided with the locating hole 12 that runs through, the stock guide 9 of corresponding location bobbin 13, holding pad 10 is provided with guide hole, hit hole pull and stretch pin hole 6, part pin hole 7 falls, tearing pin hole 8 is arranged on the corresponding cylinder steel inserts 14 respectively, then cylinder steel inserts 14 is fixed on the bed die 2 and forms on the corresponding position, end at mould is provided with scrap cutter 15, so that will process the waste material excision after the corn, prevent that it from hindering normally carrying out of producing.
