Abstract
The utility model discloses a mould ejection pin for manufacturing a plastic upper cover of a display. The mould ejection pin comprises a cylindrical ejection pin rod, wherein an integrated countersunk head is arranged at one end of the ejection pin rod; the other end of the ejection pin rod is an ejection end for ejecting a product; an ejection positioning block with an inverted U-shaped longitudinal cross section is arranged on the upper end surface of the ejection end; and the outer diameter of the ejection positioning block is smaller than that of the upper end surface of the ejection end. According to the utility model, the design of the conventional ejection end is changed, the mould ejection pin with the ejection positioning block is creatively designed, the conventional plane ejection mode is replaced by the stereotactic ejection mode, the ejection deviation phenomenon is not caused in the mould head ejection process, the ejection frequency can be effectively reduced, and the ejection cycle can be shortened.
Description
Technical field
The utility model relates to a kind of mold parts, especially relates to a kind of die ejector pin for the manufacture of the display upper plastic cover.
Background technology
Die ejector pin is the plastic mould accessory, in plastic mould, is commonly used to product is separated from mould.Traditional die ejector pin comprises the cylindrical, top shank, and described thimble rod one termination is for being used for the termination that ejects of ejecting product, and another termination is the countersunk head with described thimble rod Construction integration; It is described that to eject the upper surface that the termination contacts with product be plane layout; When needs ejected moulded products, the thimble rod of die ejector pin stretched out from the installing hole in the mould; In actual production process; die ejector pin directly ejects goods with the plane; often can eject in the process of stub bar at die ejector pin; stub bar can be by the thimble top partially; cause ejecting and have some setbacks, even stub bar needs at most time can to eject, prolonged ejection cycle; thereby so that the lengthening of whole molding cycle, and owing to eject the acceleration damage that the increase of number of times also can cause mould.
Therefore, need exploitation badly and a kind ofly can overcome defects, to realize the die ejector pin for the manufacture of the display upper plastic cover that ejects smoothly of mould stub bar.
The utility model content
The purpose of this utility model proposes a kind ofly can overcome defects exactly, realizes the die ejector pin for the manufacture of the display upper plastic cover that ejects smoothly of mould stub bar.
The utility model is to solve the problems of the technologies described above a kind of die ejector pin for the manufacture of the display upper plastic cover of the technical scheme that adopts, and comprises the cylindrical, top shank, and described thimble rod one termination is provided with the countersunk head of Construction integration; It is characterized in that: another termination of described thimble rod is for being used for the termination that ejects of ejecting product, and the described upper surface that ejects the termination is provided with realizes the three-dimensional locating piece that ejects that ejects of locating.
Further preferably, the described longitudinal section that ejects locating piece is the inverted U cross section.
Further preferably, the described external diameter of locating piece that ejects is all less than the described upper surface external diameter that ejects the termination.
The beneficial effect of a kind of die ejector pin for the manufacture of the display upper plastic cover of the utility model is: described die ejector pin has changed the design that in the past ejects the termination, the creationary die ejector pin that ejects locating piece with aforesaid of designing, the mode that conventional planar is ejected is changed into three-dimensional location and is ejected, realize that the mould stub bar is in the process that ejects, inclined to one side phenomenon can not appear pushing up again, can effectively reduce and eject number of times, shortened ejection cycle, thereby whole molding cycle is shortened, simultaneously owing to ejecting the damaged condition that the minimizing of number of times has also reduced mould, prolong the mold use life-span, improved the quality of product.
Description of drawings
Fig. 1 is the structural representation of a specific embodiment of the present utility model.
Fig. 2 is the application schematic diagram of this specific embodiment.
Fig. 3 is the enlarged diagram that ejects locating piece and stub bar part of A section among Fig. 2.
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 die ejector pin for the manufacture of the display upper plastic cover of the present embodiment comprises cylindrical, top shank 1, and thimble rod 1 one terminations are provided with the countersunk head 2 of Construction integration; Another termination of thimble rod 1 ejects termination 3 for what be used for ejecting product, the upper surface that ejects termination 3 be provided with the longitudinal section be the inverted U cross section eject locating piece 4, eject the external diameter of locating piece 4 all less than the described upper surface external diameter that ejects termination 3.
Exemplary, the application of this specific embodiment is shown in accompanying drawing 2 and accompanying drawing 3.Make the mould of display upper plastic cover when the demoulding, adopt die ejector pin to eject stub bar 5, eject the positioning relation that exists between locating piece 4 and the stub bar 5 as shown in Figure 3, guaranteed that stub bar is unlikely to be pushed up partially when ejecting, thereby stub bar is ejected in mould smoothly.
In other specific embodiments, the utility model can also be done corresponding distortion, as eject the shape of locating piece can also be for other shapes, such as taper shape, cylindricality or other irregular three-dimensional shapes.
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.
