Description

A kind of wear-resisting knife mold of abnormal shape

Technical field

The utility model relates to a kind of mold more particularly to a kind of wear-resisting knife molds of abnormal shape.

Background technique

The right side for the product of resistance to sharpening begins with a fillet and turn left downwards from centre to be extended always, until the left end of product Face, and thickness direction of the product from right side to left side is more and more thinner.

It please refers to shown in Fig. 8 to Fig. 9, used wear-resisting knife mold includes mold core 91, upper punch 92, low punch 93, limit Device 94, two-way cushion block 95 and heelpiece 96 etc., mold core 91 are equipped with die cavity, and the lower end of upper punch 92 and the upper end of low punch 93 are placed in this In membrane cavity, and it is opposite up and down, and 93 upper end of low punch has arc corners 930, and production procedure is as follows: (1) heelpiece 96 is symmetrical It puts well；(2) mold core 91 is placed on heelpiece 96；(3) low punch 93 is put into from the top of mold core 91 until bottommost；(4) it charges； (5) it is put into two-way cushion block 95；(6) upper punch 92 is put into progressive die chamber above mold core 91；(7) it is put into limiter 94；(8) pressure is used Machine presses upper punch 92 from top to bottom, unclamps again press machine after pushing down limiter 94；(9) two-way cushion block 95 is extracted；(10) again It is pressed from top to bottom with press machine, unclamps again press machine after mold core 91 is pressed onto heelpiece 96；(11) limiter 94 and heelpiece are taken away 96；(12) mold core 91 is pushed down toward bottom knockout with stripper until product 97 deviates from die cavity.

There are following several disadvantages using the production of above-mentioned mold: (1) because 93 upper end of low punch is too sharp, being easy when operating operation It breaks；(2) in operation, low punch 93 is not lacked, and be pressurized at 930 position of arc corners maximum in production pressing process, out The case where now lacking formed punch is very frequent, and after producing several products, the position of 93 upper end arc corners 930 of low punch is easy bad；(3) Maintenance needs at least three days of a low punch 93 are lacked, production efficiency is extremely low.

Utility model content

Specific embodiment

Further details of explanation is done to the utility model with reference to the accompanying drawings and detailed description, but it should reason Solution is not limited by the specific implementation for the protection scope of the utility model.

Refering to Figure 1, the utility model discloses a kind of wear-resisting knife mold of abnormal shape, including mold core 4, upper punch 1, limit Device 2, die sleeve 3, mold core 4, low punch 6, Bidirectional-pressure cushion block 7 and heelpiece 8, low punch 6 are placed on two-way cushion block 7, and it is two-way plus Pressure pad block 7 is placed on heelpiece 8.

Please refer to shown in Fig. 2 to Fig. 3, upper punch 1 include the first front end face 11, the first rear end face 12, the first left side 13, First right side 14, the first upper surface 15 and the first lower end surface 16, the first lower end surface 16 is horizontal plane, for suppressing object downwards Material.

It please refers to shown in Fig. 4 to Fig. 5, mold core 4 is nested in die sleeve 3, and mold core 4 is equipped with receiving 1 lower end of upper punch and undershoot First type chamber 40 of first 6 upper end.

It please refers to shown in Fig. 6 to Fig. 7, low punch 6 includes the second upper surface 601, the second lower end surface 602, the second front end face 61, inner face 621 behind the second rear end face 62, the second left side 63, the second right side 64, second, the second right inner face 641 and interior Bottom surface 65, inner face 621 after second, the second right inner face 641 are formed with one between 40 inner sidewall of inner bottom surface 65 and the first type chamber Second type chamber 60, second type chamber 60 are that recess is formed downwards from the second upper surface 601, and second type chamber 60 is contained in the first type chamber 40, it is a part of the first type chamber 60, is designed in this way, the product produced is hardly visible spue line, product appearance On all straight flanges and fillet or angle joint be very smooth round and smooth.1 upper end of upper punch is placed in limiter 2, under End is placed in second type chamber 60.Inner face 621 and the second right inner face 641 after the second of low punch 6, first with upper punch 1 Rear end face 12 is consistent with 14 profile of the first right side.Circular arc is equipped with close to the adjoiner of the second right inner face 641 on inner bottom surface 65 Turning 66.

The second front end face 61, the second rear end face 62, the second left side 63, second of first type chamber, 40 inner wall and low punch 6 The profile of right side 64 is consistent.When work, material is placed in second type chamber 60, low punch 6 is motionless, and upper punch 1 moves up and down Far from or close to low punch 6, material compression moulding in second type chamber 60 is realized, product 5 is ultimately formed, due to upper punch 1 It is maintained at up and down in second type chamber 60, material is lower than the upper end of low punch 6, and material will not be to the sharper place in 6 upper end of low punch It is suppressed, prevents 6 upper end of low punch from being broken, extend the service life of low punch 6.

The resistance to sharpening shape produced in the special-shaped wear-resisting knife mold of the utility model is that a point of a knife is small, knife tail is wide as cattle horn shape Shape, and have point or so two, according to existing mold design mode, a product needs one set of die, practical new using this The special-shaped wear-resisting knife mold of type, which produces two product, can share the same mold core 4, as long as changing formed punch 1, low punch 6.

Advantage of the special-shaped wear-resisting knife mold of the utility model compared with existing mold in production efficiency and production cost is such as Under:

1,6 long service life of low punch of the utility model, can be used for multiple times, and save cost.

2, wear-resisting two product of knife mold of the utility model can share a mold core, which offers a saving mold core at This.

3, low punch 6 will not just will affect production efficiency because often lacking formed punch, improve production efficiency, shorten delivery week Phase.

4, because formed punch will not be lacked, the time of maintenance has just been lacked, a class can normally produce, and improve production efficiency.

5,100,000 products can be at least produced in the case where 6 normal use of low punch, reduces production cost.

6, because of the phenomenon that being not in frequent maintenance die, lacking formed punch, waste product is also just few, and qualification rate will also improve, and add The yield of upper per tour rises, and the phase is handed over to shorten, and production cost directly just has dropped.

Although for illustrative purposes, preferred embodiments of the present invention are had been disclosed, but the common skill of this field Art personnel will realize the situation of the scope of the utility model and spirit disclosed in not departing from by appended claims Under, various improvements, additions and substitutions are possible.
