Abstract
The utility model discloses a mould for manufacturing a plastic upper cover of a display. The mould comprises a male mould and a female mould matched with the male mould, wherein a rubber position for manufacturing the plastic upper cover of the display is arranged on the female mould; draft angles of 1-3 degrees are formed in the inner side walls of the rubber position; and preferably, the draft angles of 1 degrees are formed in the inner side walls at the periphery of the rubber position. According to the mould, the draft angles are formed in the inner side walls of the original rubber position for the convenience of demoulding, so that the mould is not frequently damaged by pulling when being opened, the product appearance is better protected, and the appearance effect is better.
Description
Technical field
The utility model relates to mould applications, especially relates to a kind of mould for the manufacture of the display upper plastic cover.
Background technology
The display upper plastic cover is to be formed by the mould injecting glue.Original mould that uses has comprised a male model and a master mold that cooperates with it, and madial wall is vertical plane around the described master mold, and in production practices, we find that phenomenon often appears pulling in product when die sinking.
Therefore, need exploitation badly and a kind ofly can overcome defects, can often not occur pulling the mould for the manufacture of the display upper plastic cover of phenomenon when suffering die sinking to realize product.
The utility model content
The purpose of this utility model proposes a kind ofly can overcome defects exactly, realizes that the mould for the manufacture of the display upper plastic cover of phenomenon can often not appear pulling in product when die sinking.
The utility model is to solve 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, comprise a male model and one and the adaptive master mold of male model, be provided with the glue position for the manufacture of the display upper plastic cover on the described master mold, described glue position madial wall is provided with 1-3 ° pattern draft.
As further improvement of the utility model, madial wall is provided with 1 ° pattern draft around the described glue position.
The beneficial effects of the utility model are: increase pattern draft in original glue position madial wall, conveniently stripped, so that phenomenon can often not occur pulling during die sinking, product appearance is better protected, and appearance effect is better.
Description of drawings
Fig. 1 is the structural representation of an implementation of the present utility model.
Fig. 2 is the structure enlarged diagram of a specific embodiment glue position of the present utility model.
The specific embodiment
In order to be illustrated more clearly in the utility model embodiment 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 embodiment more of the present utility model, 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, comprise a male model 1 and one and the adaptive master mold 2 of male model 1, be provided with the glue position 3 (as shown in Figure 2) for the manufacture of the display upper plastic cover on the master mold 2, madial wall 4 is provided with 1 ° pattern draft β around the glue position 3, certainly, the madial wall 4 of glue position 3 can also be set to the pattern draft β of other angles such as 2 ° or 3 °.
Exemplary, the application of the present embodiment is such: improve existing mold according to said structure and add pattern draft β, and when producing the mould temperature is set in 100 °, so that product strengthens amount of contraction when die sinking, cooperate pattern draft, so that be unlikely to be pulled by master mold during product stripping.
The above only is preferred embodiment of the present utility model; should be pointed out that for those skilled in the art, under the prerequisite that does not break away from the utility model principle; can also make some improvements and modifications, these improvements and modifications also should be considered as protection domain of the present utility model.
