Abstract

A kind of structure for molding foaming, including moulding section, die sinking sync section, ejection part, the moulding section include cavity plate (2), punch-pin (3), male mold inserts (10), injecting products (1);The die sinking sync section includes backing plate (4), upper ejector pin fixed plate (6), upper push pedal (7), synchronous push rod (13), nitrogen spring (11), brute spring (12);The ejection part point includes oil cylinder (5), upper ejector pin fixed plate (6), upper push pedal (7), lower push rod fixed plate (8), lower push pedal (9), synchronous push rod (13), push rod (14);It is characterized in that:Punch-pin (3) floats by nine nitrogen springs (11) to realize floating;Simultaneously, push rod (14) is fixed in upper ejector pin fixed plate (6), synchronous push rod (13) is fixed in lower push rod fixed plate (8), it is synchronous with upper push pedal (7) holding by 8 brute springs (12) and lower push rod fixed plate (8) is located in lower push pedal (9).This structure, it is simple and reliable, it can effectively solve the problems, such as product cross section wall unevenness.

Description

A kind of structure for molding foaming
Technical field
The utility model is related to a kind of structure for molding foaming, that is to say, that provide a kind of effectively solution for injection mold The new construction of the injection mold of product cross section wall unevenness.
Background technology
The shape of mould product becomes increasingly complex, in traditional injection moulding, product cross section wall unevenness, larger wall unevenness meeting Cause product to shrink, cause the buckling deformation of product, have impact on the size and weight of product.Accordingly, it is desirable to provide a kind of effective Solve the new construction of the injection mold of product cross section wall unevenness.
The content of the invention
To solve the above problems, the utility model proposes a kind of technical scheme, i.e.,:A kind of structure for molding foaming, including Moulding section, die sinking sync section, ejection part, the moulding section include cavity plate (2), punch-pin (3), male mold inserts (10), Injecting products (1);The die sinking sync section includes backing plate (4), upper ejector pin fixed plate (6), upper push pedal (7), synchronous push rod (13), nitrogen spring (11), brute spring (12);The ejection part point includes oil cylinder (5), upper ejector pin fixed plate (6), upper push pedal (7), lower push rod fixed plate (8), lower push pedal (9), synchronous push rod (13), push rod (14);It is characterized in that:Punch-pin (3) floats and leaned on Nine nitrogen springs (11) realize floating;Meanwhile, push rod (14) is fixed in upper ejector pin fixed plate (6), synchronous push rod (13) Be fixed in lower push rod fixed plate (8), and lower push rod fixed plate (8) be located at lower push pedal (9) on, by 8 brute springs (12) with Upper push pedal (7) keeps synchronous.
This is simple and reliable for structure, is floated foaming using die sinking, can be effective come the foamed zones of the local thickness that controls die cavity The problem of solving product cross section wall unevenness.
Brief description of the drawings
Accompanying drawing 1 is the product structure figure of embodiment of the present utility model.
Accompanying drawing 2 is the structure chart of the utility model embodiment.
Accompanying drawing 3 is the part-structure sectional view of the utility model embodiment.
Embodiment
Below in conjunction with the accompanying drawings and example is further described to the utility model.
As a kind of embodiment, its technical scheme is:I.e.:A kind of structure for molding foaming, including moulding section, die sinking are together Step part, ejection part, the moulding section include cavity plate 2, punch-pin 3, male mold inserts 10, injecting products 1;The die sinking is synchronous Part includes backing plate 4, upper ejector pin fixed plate 6, upper push pedal 7, synchronous push rod 13, nitrogen spring 11, brute spring 12;The ejection Part includes oil cylinder 5, upper ejector pin fixed plate 6, upper push pedal 7, lower push rod fixed plate 8, lower push pedal 9, synchronous push rod 13, push rod 14; It is characterized in that:Punch-pin 3 floats by nine nitrogen springs 11 to realize floating;Meanwhile, push rod 14 is fixed on upper ejector pin fixed plate 6 On, synchronous push rod 13 is fixed in lower push rod fixed plate 8, and lower push rod fixed plate 8 is located in lower push pedal 9, by 8 brute springs 12 keep synchronous with upper push pedal 7.
During work, punch-pin 3 floats by nine nitrogen springs 11 to realize floating 1.6mm, product foamed zones wall thickness 3.1mm;Not foamed zones wall thickness 2.5mm, by the floating 1.6m of punch-pin 3.
This structure is floated foaming using die sinking, come the foamed zones of the local thickness that controls die cavity, efficiently solves production The problem of product section wall unevenness.Meanwhile, injection machine dwell pressure and dwell time are reduced, injection cycle is shortened;Reduce Mold temperature.Because of plastic viscosity reduction, same filling speed, injection pressure can lower 34%;Because reducing in die cavity Pressure, reduces the generation of overlap, reduces internal stress, extends die life, reduces locked mode pressure, alleviate the weight of product Amount.
