Abstract
The utility model belongs to the field of manufacturing of moulds and discloses a double-color injection mould. The double-color injection mould comprises a first nozzle and a second nozzle, wherein the first nozzle is connected with a first mould core; the second nozzle is connected with a second mould core; the second mould core is fixed on a fixed plate; the fixed plate is connected with a first oil cylinder. The work principle is that double-color injection molding is realized by withdrawal of the second mould core. Two sets of mould finished products are reduced into one set of mould finished product, so work efficiency is greatly improved, the injection mould does not need to rotate in the application process, and the product quality is easy to control. The double-color injection mould is simple in structure, low in manufacturing cost and favorable for large-area popularization.
Description
Technical field
The utility model relates to the Mold Making field, is specifically related to a kind of bicolor injection mould.
Background technology
Mould is a kind of instrument of producing the product that definite shape and dimensional requirement are arranged, the reasonability of mould structure and machining accuracy etc. have direct impact to quality and the production efficiency of product, therefore countries in the world are all very paid close attention to the design and fabrication technology of mould, all trying to explore new technology, the development new equipment is to meet the needs of Modern Mold development.
Double-shot moulding has been widely applied to electronic product, electric tool, medical product now, household electrical appliances, the plastic cement field that toy etc. is nearly all, a kind of method of double-shot moulding is to use two molds at present, after the first mould molding completes the first material product, put into the second mould, further moulding the second material product, this kind of method needs two molds, in actual production process, operation is trouble and the control of difficult quality handle very, is only suitable for the goods that quality requirements is lower; Another more advanced method is exactly to adopt the injection machine with two front moulds and a rear mold to complete double-shot moulding, die sinking after the first forming materials completes, one side Rotate 180 degree of further injection molding machine, further matched moulds start injection the second material is to form end article, this kind of method need to adopt the injection machine with spinfunction, not only cost is high, and because injection machine has two front moulds and a rear mold, required precision to mould is very high, causes enterprise to need substantial contribution to put into above mould.
The Chinese patent that the patent No. is CN201516677U, a kind of bicolor injection mould is disclosed, its technical scheme adopts mold cavity assembly and mold cores assembly to locate and be combined into injection mold by alignment pin, ejecting push rod one end withstands on the mold cores assembly, described technical scheme contributes to reduce die cost, but, because its structure is too simple, complicated a little any product just is difficult to produce with it.
The Chinese patent that publication number is 200610061499.2, a kind of bicolor injection mould is disclosed, described mould contains front mould and rear mold, and front mould and rear mold all contain a plurality of slide blocks, the parts that described technical scheme contains a plurality of complexity, in the process of practical application, to the required precision height very of mould, the material of making mould is also had to high requirement, be unfavorable for spread and production.
The Chinese patent that application number is 200910107954.1, a kind of bicolor injection mould is disclosed, its technical scheme adopt by above dynamic model slidably in guide pillar realize double-shot moulding, its defect is need to be by the acting in conjunction of fixed half and moving half, Product Precision is difficult to control.
The Chinese patent that application number is 200910101626.0, disclose a kind of double coloured plastic injection machine, and described injection machine needs fixed half and moving half, and in the process of application the Rotate 180 degree, Product Precision is difficult to control.
The utility model content
Reasonable in order to meet double-shot moulding function and the product structure that can produce different product, cost is low, and the utility model provides a kind of bicolor injection mould.
Described a kind of bicolor injection mould, comprise base plate, be provided with ejector retainner plate above described base plate, described bicolor injection mould also comprises the first nozzle, the second nozzle, and described the first nozzle is connected with the first core, and described the second nozzle is connected with the second core, described the second core is fixed on above fixed head, described fixed head is connected with the first oil cylinder, and described the first nozzle is connected with the first flow distribution plate, and described the second nozzle is connected with the second flow distribution plate.
Wherein, the first nozzle is for injecting body, and the second nozzle is for injecting flexible glue.
Wherein, the second core glides when preventing the first nozzle injection, and described the second core is connected with the second oil cylinder by the oil cylinder mold insert.
Wherein, described fixed head is by the limited block connection backing plate.
The utility model operation principle: the first step, the mould matched moulds, the first nozzle starts injection, further moulding the first material product; Second step, the second oil cylinder drives the oil cylinder mold insert and leaves the second core, and further the first oil cylinder drives the second core by fixed head and moves down, and when fixed head arrives the backing plate place, the second nozzle starts injection, further moulding the second material; The 3rd step, the second material and the first material merge and form end article; The 4th step, die sinking after supercooling, thimble ejects goods.
The utility model completes goods by two molds and is reduced to a mold and completes goods, and operating efficiency significantly improves, simultaneously in the injection mold application process without rotation, product quality is easy to control.The utility model is simple in structure simultaneously, and cost of manufacture is low, is beneficial to spread.
