Abstract
The utility model relates to a mould ultralong in service life, which is used for batch plastic production and comprises a positioning ring (1), an upper fixed plate (2), a female mould plate (3), a male mould plate (5), a female mould backing plate (6), an ejector plate (7), an ejector backing plate (8), a mould pin (9), a lower fixed plate (10), a supporting column (11), a plate push guide column (21), a reset rod (19), a reset spring (20), a temperature control system (17) and connecting screws (12, 13, 14 and 15). The positioning ring (1) is positioned on a machine, the female mould plate (3) and the male mould plate (5) are made of alloy mold steel, a guide column and a guide sleeve (4) are mounted on the male mould plate and the female mould plate respectively, the freedom degrees of the male mould plate and the female mould plate in the X-axis direction and the Y-axis direction are limited by a concave-convex fine positioning unit (16), and the plate pushing guide column (21) is used for guiding the ejector plate so that the ejector plate can move stably. During assembly of the mould, the ejector plate can reset to the original position in advance by the aid of the reset rod (19) and the reset spring (20), and the temperature of the mould is controlled by the temperature control system (17).
Description
Technical field
The utility model relates to a kind of mould that carries out the superelevation life-span of plastic product production use in enormous quantities.
Background technology
In the modern life, production in enormous quantities is the inevitable development direction that reduces cost and boost productivity, and general die life is limited; The output that the same mould of a lot of covers satisfies plastic product to be done during mass production, a lot of raw-material inputs can be increased, designer's input; In order to make such mould, also to drop into a lot of machinery equipments, increase a lot of material resources and human resources; For reducing cost, carrying out large quantities of volume productions with a mold is effective methods.The development of modern machine and cutter, more and more ripe for the technology of processing die, core rod, mould standard spare and other the accessory of mould have the very high life-span now, and the bottleneck that influences die life goes out on mould bases.
Summary of the invention
For solving above-mentioned prior art problem; The utility model proposes the mould in a kind of superelevation life-span, comprising: centring ring 1 is used to be positioned at machine, 2 fixing usefulness of upper mounted plate, caster 3, adopts alloy die steel; Hardness is accomplished HRC48-52 °, male model plate 5; Adopt alloy die steel, hardness is accomplished HRC48-52 °, and they install the mold insert that has moulding respectively.Guide pillar, guide pin bushing added and are not installed on the male and female template in 4 minutes, were used for male model and master mold and when matched moulds, play the guiding role, and concave-convex fine positioning 16 leans on jog accurately to locate; Four direction, they have limited the X of male and female template, the free degree of Y direction respectively, and cavity support plate 6 strengthens the rigidity and the processability of caster, ejector retainner plate 7; Thimble backing plate 8 through thimble, ejects workpiece from die cavity, mould pin 9; Assurance ejects the activity space of part, upper mounted plate 2, bottom plate 10, support column 11; Push pedal guide pillar 21 is used for the guiding of ejector retainner plate, makes the ejector retainner plate easy motion, and release link 19 makes ejector retainner plate return to the origin-location in advance by release link when matched moulds; Back-moving spring 20, the temperature of a whole set of mould of temperature control system 17 controls connects compositions such as screw 12,13,14,15.
The utility model adopts alloy die steel to carry out the template of Quenching Treatment; The hardness that makes it is to HRC48-52 °; Make the crystal of material change state; Thereby antifatigue, the resistance to deformation of increase template, the rigidity, toughness and other the mechanical performance that strengthen template improve greatly, make the progress that a leap is arranged die life.
Since caster and male model plate use alloy die steel, the rigidity of Precision Machining after heat treatment, so its fatigue resistance, material, toughness, anti-deformation all have very raising, dimensional stability all very good.
The main application of the superhard mould of the utility model is to improve the service life of mould, reduces raw material, equipment and personnel's production cost.

The specific embodiment
Embodiment 1
As illustrated in fig. 1 and 2; The mould in a kind of superelevation life-span comprises: centring ring 1 is used to be positioned at machine, 2 fixing usefulness of upper mounted plate, caster 3, adopts alloy die steel; Hardness is accomplished HRC48-52 °, male model plate 5; Adopt alloy die steel, hardness is accomplished HRC48-52 °, and they install the mold insert that has moulding respectively.Guide pillar, guide pin bushing added and are not installed on the male and female template in 4 minutes, were used for male model and master mold and when matched moulds, play the guiding role, and concave-convex fine positioning 16 leans on jog accurately to locate; Four direction, they have limited the X of male and female template, the free degree of Y direction respectively, and cavity support plate 6 strengthens the rigidity and the processability of caster, ejector retainner plate 7; Thimble backing plate 8 through thimble, ejects workpiece from die cavity, mould pin 9; Assurance ejects the activity space of part, upper mounted plate 2, bottom plate 10, support column 11; Push pedal guide pillar 21 is used for the guiding of ejector retainner plate, makes the ejector retainner plate easy motion, and release link 19 makes ejector retainner plate return to the origin-location in advance by release link when matched moulds; Back-moving spring 20, the temperature of a whole set of mould of temperature control system 17 controls connects compositions such as screw 12,13,14,15.
In the mould use, male model plate, caster are used general common iron, and die life is about 300,000 times; Male model plate, caster are used perhardened steel; General die life, the utility model mould adopted alloy die steel, after heat-treating about 40-50 is ten thousand times; Material hardness can reach HRC48-52 °, can make die life to 400 more than ten thousand times like this.
