Abstract
The invention discloses a glue-feeding flowing passage structure of a mould for manufacturing the plastic upper cover of a display, comprising a glue-injecting port for being connected with an injection moulding machine, a glue-injecting passage for being conducted with each cavity of the mould, and a cold slug well, wherein the glue-injecting port and the cold slug well are arranged on the glue-injecting passage in a conducting manner, and the glue-injecting passage is a Z-shaped passage; the glue-injecting passage comprises an upper passage, a lower passage and a middle passage, the upper passage, the lower passage and the middle passage form the Z-shaped passage, and the upper passage and the lower passage are vertically arranged on the two end heads of the middle passage in a conducting manner; and the cold slug well is formed by the outwards linear extension of the two end heads of the middle passage. According to the invention, the direct glue-feeding mode of the previous mould for manufacturing the plastic upper cover of the display is changed into a glue-feeding mode adopting the Z-shaped passage, and the cold slug well is additionally arranged, thus the glue-feeding flowing passage structure of the mould for manufacturing the plastic upper cover of the display is realized, wherein in the structure, a cold slug part cannot be completely injected in a product during a glue-injecting process, and obvious rushing-in traces are avoided at the glue-injecting port.
Description
Technical field
The present invention relates to mould applications, especially relate to a kind of mould for the manufacture of the display upper plastic cover and advance solation road structure.
Background technology
The display upper plastic cover is to be formed by the mould injecting glue.In traditional mould injecting glue process, usually in the mode of directly advancing glue glue is injected mold cavity.In production practices, we find to make and have following defective in the injecting glue process of display upper plastic cover:
The cold burden part is all injected product surface, causes product surface to have the material flower;
Directly pour product surface, need to carry out pressurize in the moulding later stage, expect that rushing of cast gate place trace is more obvious, cause surface, Jiao Kou place to have plastic material to pour vestige.
Therefore, need exploitation badly and a kind ofly can overcome defects, can all not inject product to realize injecting glue process cold burden part, and the Jiao Kou place do not have obviously pour vestige advance solation road structure for the manufacture of the mould of display upper plastic cover.
Summary of the invention
Purpose of the present invention proposes a kind ofly can overcome defects exactly, realizes that injecting glue process cold burden part can all not inject product, and the Jiao Kou place does not have the mould for the manufacture of the display upper plastic cover that obviously pours vestige and advances solation road structure.
The present invention solves the problems of the technologies described above a kind of mould for the manufacture of the display upper plastic cover of the technical scheme that adopts to advance solation road structure, comprises for the gum-injecting port that is connected with injection machine, is used for glue injection channel and slag well with each die cavity conducting of mould; Described gum-injecting port and slag well conducting are arranged on the described glue injection channel, and described glue injection channel is the Z-type passage.
As a further improvement on the present invention, described glue injection channel comprises upper channel, lower channel and center-aisle, described upper channel, lower channel and center-aisle form described Z-type passage, and described upper channel and lower channel vertical conducting are arranged on the two ends of described center-aisle, have further improved and have reduced the washmarking degree that injecting glue produces.
As a further improvement on the present invention, described slag well is that the outside straight line of described center-aisle two ends extends to form, and further effectively reduces cold burden and is flushed in the product.
The invention has the beneficial effects as follows: describedly advance mode that mould that the structural change of solation road originally made the display upper plastic cover directly advances glue and change to the Z-type passage and advance glue, and add slag well.Change to the Z-type passage and advance glue so that when advancing glue by turning round so that plastic cement has a buffering, be unlikely to directly to pour product, cause product surface to produce serious current mark; Add slag well and realized that the cold burden part of moulding front end can enter in the described slag well, reduce on the runner product as far as possible, cause surface material flower.Description of drawings
Fig. 1 is the application schematic diagram of this specific embodiment.
Fig. 2 is the structural representation of a specific embodiment of the present invention.
The specific embodiment
In order to be illustrated more clearly in the embodiment of the invention or technical scheme of the prior art, the below will do to introduce simply to the accompanying drawing of required use in embodiment or the description of the Prior Art, apparently, accompanying drawing in the following describes only is some embodiments of the present invention, for those of ordinary skills, under the prerequisite of not paying creative work, can also obtain according to these accompanying drawings other accompanying drawing.
As shown in Figure 1, a kind of mould for the manufacture of the display upper plastic cover of the present embodiment advances solation road structure, comprises for the gum-injecting port that is connected with injection machine, is used for glue injection channel and slag well with each die cavity conducting of mould; Described gum-injecting port and slag well conducting are arranged on the described glue injection channel, and described glue injection channel 1 is the Z-type passage.
The further specific embodiment as the present embodiment, in conjunction with shown in Figure 2, glue injection channel 1 comprises upper channel 3, lower channel 4 and center-aisle 2, upper channel 3, lower channel 4 and center-aisle 2 form the Z-type passage, and upper channel 3 and lower channel 4 vertical conductings are arranged on the two ends of center-aisle 2, gum-injecting port is arranged on the centre position of center-aisle 2, and upper channel and lower channel connect and be connected in the mold cavity.Be flushed in the product for further effectively reducing cold burden, slag well 5 extends to form for the outside straight line of center-aisle 2 two ends, and certain, slag well also can be that other forms of well body is arranged on other positions of glue injection channel.
Exemplary, the present embodiment is to use like this: glue-injection machine is connected on the gum-injecting port 6, injects colloid, and the center-aisle 2 that advances glue by the Z-type passage is diverted in upper channel 3 and the lower channel 4, colloid flows out after buffering has been realized in the corner again, avoids occurring serious washmarking; The slag well 5 that arranges has reduced cold burden and has flowed in the product so that the cold burden of moulding front end partly enters in the described slag well, causes surface material flower.
The above only is preferred embodiment of the present invention; should be pointed out that for those skilled in the art, under the prerequisite that does not break away from the principle of the invention; can also make some improvements and modifications, these improvements and modifications also should be considered as protection scope of the present invention.
