Abstract
The utility model discloses a positioning column structure applicable to injection molding. The positioning column structure is characterized by comprising a central block and a plurality of ribs which are integrally formed together with the central block, wherein each rib is provided with a first end part and a second end part; the first end parts of the ribs are connected with the central block to enable the central block and the ribs to form a whole body; and the second ends of the ribs are separated from the central block. According to the positioning column structure applicable to the injection molding, the second parts of the ribs of the conventional positioning column structure applicable to the injection molding are treated in a complete smoothing way, so that the edges on the conventional second end parts are removed, molten plastic can be quickly filled in each part of the positioning column structure applicable to the injection molding along the second end parts which are completely smoothened, and therefore, the shortcomings such as bubble occurrence can be avoided, the yield of products under the injection molding can be greatly improved, and the structural strength of the products can be greatly ensured.
Description
Technical field
The utility model relates to a kind of locating dowel structure that is suitable for injection mo(u)lding, especially relates to a kind ofly for the locating dowel structure that is suitable for injection mo(u)lding on the plastics touch-screen frame mold, belongs to the Design of Plastic Mould field.
Background technology
When making the touch-screen framework; need to use the touch-screen frame mold; touch-screen frame mold structure needs to use the locating dowel structure sometimes; locating dowel structure of the prior art has corner angle usually; the plastic cement that this angular type end usually can hinder molten is full of die cavity fully rapidly; therefore and be not suitable for injection molding, usually can cause the yield of product of injection mo(u)lding lower, this structure also is difficult to guarantee the structural strength of product in addition.
The utility model content
In order to overcome the deficiencies in the prior art, the purpose of this utility model is to provide a kind of locating dowel structure that is suitable for injection mo(u)lding, and it is lower to solve preferably in the prior art product yield of injection mo(u)lding, the problem that structural strength is difficult to guarantee.
The utility model is achieved through the following technical solutions:
Be suitable for the locating dowel structure of injection mo(u)lding, it is characterized in that, comprise: the integrated rib of central block and some and above-mentioned central block forms, described rib has first kind end and Equations of The Second Kind end, the first kind end of described rib is connected with described central block makes above-mentioned central block and rib consist of an integral body, and Equations of The Second Kind end and the described central block of described rib are separated from each other.
Further, the Equations of The Second Kind end of described rib is complete fillet.
Further, described rib is " one " font, " ten " font, in " soil " font any.
Further, the cross section of described rib be in square, trapezoidal, the triangle any.
Further, each described central block is fixedly connected with four described ribs, and the first kind end of described rib distributes symmetrically with described central block.
The beneficial effects of the utility model are: the utility model has carried out the processing of Full Round to the Equations of The Second Kind end of existing locating dowel structure center rib, the corner angle on the existing Equations of The Second Kind end have been eliminated, so that the plastic cement of molten can be full of fast along the Equations of The Second Kind end of complete fillet the various piece of locating dowel structure, thereby avoid occurring the defectives such as bubble, improve widely the yield of the product of injection mo(u)lding, effectively guaranteed the structural strength of product.
Description of drawings
Fig. 1 is a kind of structural representation of touch-screen frame mold;
Fig. 2 is the enlarged drawing of locating dowel structure described in the described touch-screen frame mold of Fig. 1;
Fig. 3 is the structural representation that is suitable for the locating dowel structure of injection mo(u)lding described in the utility model.
Main Reference numeral implication is among the figure:
1, is suitable for locating dowel structure 2, central block 3, the rib of injection mo(u)lding.
The specific embodiment
Below in conjunction with accompanying drawing, describe the specific embodiment of the present utility model in detail:
Fig. 1 is the structural representation of existing a kind of touch-screen frame mold; Fig. 2 is the enlarged drawing of locating dowel structure described in the described existing touch-screen frame mold of Fig. 1; Fig. 3 is the structural representation that is suitable for the locating dowel structure of injection mo(u)lding described in the utility model.
Shown in Fig. 1-2, the locating dowel structure 1 that is suitable for injection mo(u)lding described in the utility model, in reality processing be connected with other partial fixings of touch-screen frame mold.As shown in Figure 3: the locating dowel structure 1 that is suitable for injection mo(u)lding, formed by central block 2 and some ribs 3, rib 3 has first kind end and Equations of The Second Kind end, the first kind end of rib 3 is fixedly connected with central block 2, Equations of The Second Kind end and the central block 2 of rib 3 are separated from each other, it is characterized in that the Equations of The Second Kind end of rib 3 is complete fillet.
This shows, just because of the utility model the processing of Full Round has been carried out in the Equations of The Second Kind end of existing locating dowel structure 1 center rib 3, the corner angle on the existing Equations of The Second Kind end have been eliminated, so that the plastic cement of molten can be full of fast along the Equations of The Second Kind end of complete fillet the various piece of the locating dowel structure 1 that is suitable for injection mo(u)lding, thereby avoid occurring the defectives such as bubble, improve widely the yield of the product of injection mo(u)lding, effectively guaranteed the structural strength of product.
It should be noted that the locating dowel structure 1 that is suitable for injection mo(u)lding described in the utility model can be applied to the touch-screen frame mold, also can be applied to the mould of other types.Simultaneously, the utility model does not limit the factors such as the concrete material selection, concrete shape structure, size of central block 2 and rib 3, and those skilled in the art can be selected according to actual conditions.Can be " one " font such as rib 3, also can be " ten " font, " soil " font or other shapes.Can be square, trapezoidal, triangle or other shapes such as the cross section of rib 3 again.In addition, the utility model does not limit the mode that is fixedly connected with of rib 3 and central block 2 yet, the factors such as concrete link position of the quantity of the rib 3 that is connected with central block 2 or rib 3 and central block 2, those skilled in the art can be selected according to actual conditions equally.Preferred as the utility model, each central block 2 is fixedly connected with four root bars 3, and the first kind end of these ribs 3 distributes symmetrically with central block 2.This optimal way can further improve the yield of product of injection mo(u)lding and the structural strength of product.
Below disclose the utility model with preferred embodiment, so it is not to limit the utility model, and all employings are equal to replaces or technical scheme that the equivalent transformation mode obtains, all drops within the protection domain of the present utility model.
