Abstract
The utility model discloses an injection mould with multiple cavities, relating to the technical field of injection mould. The utility model aims at solving the problem existing in the current injection mould with multiple cavities that the similarity of qualities of the formed products can not be ensured caused by unevenness of flow passage arrangement. The utility model comprises an upper mould and a lower mould, which are cooperated with each other; the upper mould is composed of an upper flow passage plate, a lower flow passage plate, an upper insulating board, an upper heating board and an upper mould board, which are sequentially and fixedly connected from the top to the bottom; the lower mould is composed of a lower mould board, a lower mould heating board, a lower mould insulating board and a lower mould fixing board, which are sequentially and fixedly connected from the top to the bottom; the upper flow passage plate and the lower flow passage plate are provided with flow passages symmetrical along the axle line. The utility model is particularly suitable for producing small injection products in mass production.
Description
Technical field
This patent relates to the injection mold technical field, relates in particular to a kind of multi-point mould injection mold.
Background technology
Injecting molding die is that the sizing material that preheats into mecystasis is injected the mould first cure through the running gate system of injection mould, is applicable to make large-scale, heavy wall, thin-walled, complex-shaped rubber.
The basic structure of injecting molding die 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, by core (moulding plastic interior shape), die cavity (moulding plastics outer shape), curved lever and formation such as insert; Three, constitutional detail plays installation, guiding in mould, effects such as mechanism action and temperature adjustment, and guide elements is like guide pillar, guide pin bushing, and Assembly part is like crack, location, fixed clamping plate, solid plate, moving platen, dynamic model backing plate and mould pin etc.
Wherein, runner be molten plastic from the ejaculator nozzle to die cavity must channel.Flow passage system comprises sprue, runner and cast gate.The multi-point mould mould has a plurality of identical die cavities, can produce a plurality of products simultaneously by an injecting glue, can improve the production efficiency of injecting products greatly.Therefore, in the multi-point mould mould, conventional runner setting such as imbalance, molten plastic can not fill up each die cavity simultaneously, and then the quality of each die cavity moulding article can not guarantee unanimity, so that can not satisfy the production requirement of product.
The utility model content
In existing multi-point mould mould,, runner cause moulding article quality can not guarantee consistent deficiency because of being provided with imbalance.The purpose of this patent provides a kind of multi-point mould injection mold.
This patent solves the technical scheme that its technical problem adopted: it comprises the upper die and lower die that match; Patrix by upper reaches guidance tape, dirty guidance tape, go up thermal insulation board, go up heating plate and cope match plate is affixed successively forms from top to bottom; Counterdie is by down template, counterdie heating plate, counterdie thermal insulation board and the counterdie fixed head is affixed successively from top to bottom forms, and said upper reaches guidance tape and said dirty guidance tape are provided with along the runner of axis symmetry.
The die cavity shape of cross section of said runner is H shape.
The vertical sectional shape of said runner is circular, semicircle, trapezoidal or U-shaped.
Further, said going up in heating plate and the said counterdie heating plate is evenly equipped with heating tube.
Said heating plate, counterdie heating plate and the heating tube gone up cast by Cu alloy material.
The beneficial effect of this patent is: the multi-point mould injection mold structure compact of this patent; Runner on the runner plate adopts the arrangement of balanced type; And observe the Flow of Goods and Materials behavior, and the die cavity of H shape runner does not have rapid expansion or dwindles, and fusion sizing material flow velocity is even; Guarantee many plastics consistency of product, improved the quality and the production efficiency of product.

The specific embodiment
The multi-point mould injection mold of this patent is described in conjunction with Fig. 1 to Fig. 3; This mould is a mould four cavity configurations; It comprises the upper die and lower die that match; Patrix by upper reaches guidance tape 1, dirty guidance tape 2, go up thermal insulation board 3, go up heating plate 4 and cope match plate 5 is affixed successively forms from top to bottom, counterdie is by template 6, counterdie heating plate 7, counterdie thermal insulation board 8 down and counterdie fixed head 9 is affixed successively from top to bottom forms.
Flow passage system in the mould 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; Have the function of uniform distribution plastics simultaneously for multi-cavity mold to each die cavity.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.
Upper reaches guidance tape 1 in the multi-point mould injection mold of this patent is provided with along the H shape runner 11 of axis symmetry; Molten plastic or rubber get into H shape runner 11 by sprue 12; Pass dirty guidance tape 2 successively, go up thermal insulation board 3 and go up heating plate 4 through the running channel 10 that is uniformly distributed with and get in four die cavities that constitute by cope match plate 5 and following template 6 filling of completion fusion sizing material by the die cavity charging aperture.
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.
