Abstract

The utility model discloses an injection mold provided with an X-shaped runner, relates to the technical field of injection molds, and aims to solve the problem that the form of a subrunner cavity in the conventional injection mold has both advantages and disadvantages. The injection mold comprises a cavity formed by an upper mold and a lower mold matched with each other, wherein, the upper mold comprises a panel, a runner plate and an upper template which are fixedly connected in sequence from top to bottom; the lower mold comprises a lower template, a lower mold heat insulating plate, a lower mold backing plate and a lower mold bottom plate which are fixedly connected in sequence from top to bottom; and at least an X-shaped runner respectively communicated with a gate of the cavity and a material feeding opening of the injection mold is arranged on the upper template. The injection mold is particularly suitable for producing multi-cavity injection products.

Description

A kind of injection mold with X-shaped runner
Technical field
This patent relates to the injection mold technical field, relates in particular to a kind of injection mold with X-shaped runner.
Background technology
Injection moulding is one of plastics or the high efficiency production method of rubber, also is a kind of important method of plastics and rubber molding, mainly is applicable to the shaping of thermoplastic.Its basic structure is classified as follows according to the effect difference: one, running gate system, and be about to plastics and guide the passage of die cavity into by the injector nozzle, it is by sprue, runner, compositions such as ingate and cold slug well; Two, forming part, it is the various parts that directly constitute working of plastics shape and size, is made up of core, die cavity, curved lever and inserting etc.; Three, constitutional detail plays installation, guiding, effects such as mechanism action and temperature adjustment in mould.
Wherein, runner be molten plastic from the ejaculator nozzle to die cavity must channel.Flow passage system is made up of sprue, runner and die cavity charging aperture.Sprue is meant the runner till ejaculator nozzle and part to runner that the mould sprue bush contacts.This part is that molten plastic gets into the part of flowing through at first behind the mould.Runner is the transitional region between sprue and cast gate, can make the flow direction of molten plastic obtain mild conversion.The arrangement form of flow passage system is divided into balanced type and unbalanced.Balanced type is meant runner and the sectional dimension and the equal correspondent equal of length of die cavity charging aperture from sprue on the sprue to each die cavity, can directly reach the purpose of the even charging of each die cavity.Unbalanced is meant that runner and the sectional dimension and the length of die cavity charging aperture from the sprue sprue to each die cavity is not whole correspondent equals, needs the die cavity charging aperture is designed to different size, to reach the purpose of the balanced charging of each die cavity filling simultaneously.
In the existing injection mold, the die cavity configuration of runner is linear, H shape and circular arrangement.See that from flow channel length it is the shortest that the linear runner is arranged the path, be easy to the fusion sizing material and inject die cavity fast, but its distribution on mould is even inadequately; And see that from Runner Balance H shapes circular and four chambeies are arranged better, and have the function of uniform distribution plastics simultaneously for multi-cavity mold to each die cavity, can reach the purpose of the balanced charging of die cavity filling simultaneously, but its path is longer, the sizing material temperature is difficult for controlling.It is thus clear that every kind of flow channel shape is all both advantageous and disadvantageous.
The utility model content
To the both advantageous and disadvantageous deficiency of runner cavity version in the existing injection mold.The purpose of this patent provides and a kind ofly can improve the injection mold with X-shaped runner that flow velocity can shorten path again.
This patent solves the technical scheme that its technical problem adopted: constitute die cavity by the upper die and lower die that match; Said patrix forms by panel, runner plate and cope match plate are affixed successively from top to bottom; Said counterdie is by down template, counterdie thermal insulation board, counterdie backing plate and following baffle plate is affixed successively from top to bottom forms, said cope match plate be provided with at least one respectively with the X-shaped runner of the feeding inlet of the cast gate of said die cavity and said injection mold.
On the said X-shaped runner by the equal in length of said charging aperture to the path of the said cast gate that is positioned at said X-shaped flow field end, the equal rounding off of the inwall of said X-shaped runner.
The vertical sectional shape of said X-shaped runner is circular, semicircle, trapezoidal or U-shaped.
Said cope match plate and the said edge that is positioned at said die cavity of template down are equipped with the flash limit of cross section semicircular in shape.
Further, it also comprises the liftout attachment of the shaping plastic that is used for ejecting said die cavity.
The beneficial effect of this patent is: the X-shaped runner in this patent mould, and sprue can reach the purpose of the even charging of each die cavity to the equal correspondent equal of path of the runner of each die cavity on the sprue; In addition, compare circle or H shape runner, in the X-shaped runner of inwall rounding off, the path that sizing material flows shortens, and the glue flow resistance diminishes, and more help the fusion sizing material and fill quickly and evenly, and this mould structure is simple, and is easy to manufacture.

The specific embodiment
In conjunction with Fig. 1 to Fig. 3 a kind of injection mold with X-shaped runner of this patent is described, this mould is a mould two cavity configurations, is used for producing the closed hoop sealing ring of automobile.It comprises the upper die and lower die that match, and patrix forms by panel 1, runner plate 2 and cope match plate assembly are affixed successively from top to bottom, and counterdie forms by mo(u)ld bottom half board component, counterdie thermal insulation board 7, counterdie backing plate 8 and following baffle plate 9 are affixed successively from top to bottom.For ease of the manufacturing of mould and the demoulding of goods, the cope match plate assembly is made up of first cope match plate 3 and second cope match plate 4 of suit, and the mo(u)ld bottom half board component that matches with it is made up of first time template 5 and second time template 6 of suit.Cope match plate assembly and mo(u)ld bottom half board component constitute the die cavity of sealing ring jointly, are the mould of many die joints structure.
X-shaped runner in this patent mould is the balanced arrangement mode.Communicate with charging aperture 33 on the runner plate 2 through running channel 32 at 31, two " X " shapes of two " X " shape runners runner 31 that symmetry is set on first cope match plate 3 and communicates.Running channel 32 is the taper type of downward flaring, and its tapering is 5 °.The vertical sectional shape of " X " shape runner 31 is circular, semicircle, trapezoidal or U-shaped." X " shape runner inner wall rounding off, and by identical length of charging aperture 33 to die cavity charging aperture etc., can make fused materials flow velocity uniform and stable makes the even charging of each die cavity, and product property can be consistent.The edge that is positioned at die cavity of first cope match plate 3, second cope match plate 4, first time template 5 and second time template 6 is equipped with the flash limit of cross section semicircular in shape, stops flash that goods are stuck on the mould, influences the demoulding.
In addition; Also be provided with liftout attachment in the mould, constitute by top board and the elastic mechanism that is arranged at the top board bottom, when die joint is opened; Heat-resisting brute spring generation relative motion in the elastic mechanism ejects the completion demoulding through top board with the waste material in sealing ring goods and the runner.
Those skilled in the art will recognize that; The above-mentioned specific embodiment is exemplary; Be in order to make those skilled in the art can better understand this patent content; Should not be construed as is the restriction to this patent protection domain, changes or modifies so long as disclose spiritual any being equal to of being done according to this patent, all falls into this patent protection domain.
