Abstract
The invention provides a puller pin which comprises a puller pin body and a pin head. The pin head is provided with an inverted fastener, and the inverted fastener is divided into two sections. The pin head of the puller pin is provided with the inverted fastener, and the inverted fastener is divided into the two sections, so that the width of the upper portion of the inverted fastener is consistent with that of the puller pin body, the tensile strength of the pin head of the puller pin is greatly improved, the puller pin is not easy to break when pulling a spure, and production cost is lowered.
Description
Technical field
The present invention relates to the die apparatus field, be specifically related to a kind of material pin that draws.
Background technology
When mould is three template dies, when injecting products is soft material, because product is soft material, so generally increase at mould and draw the material pin, add man-hour so that produce, take out smoothly stub bar, and traditional drawing expected latch structure generally as shown in Figure 1, the plunger of drawing the material pin of this structure only has a back-off 4, and the width of the L2 of back-off 4 is necessary sufficiently large, just can pull out stub bar, and the L2 width of increasing back-off 4 can cause the top width L1 of back-off 4 to dwindle, the reduced width of L1 can cause again when drawing stub bar, draws the material pin to be easy to be broken.
Summary of the invention
For having defects and the problem of drawing the material pin easily to break now, the purpose of the embodiment of the invention provides a kind of tensile strength material that draws large, that be not easy to fracture and sells.
In order to achieve the above object, the embodiment of the invention provides following technical scheme: a kind of material pin that draws comprises and draws material pin body, plunger; Described plunger is provided with back-off, and described back-off is divided into two sections.
Preferred as technique scheme, described back-off is divided into two sections, and whole back-off is Pear-Shaped.
Preferred as technique scheme, the opening Breadth Maximum of described back-off is with to draw material to sell the width of body consistent.
What the embodiment of the invention provided draws the material pin by establishing back-off in the plunger of drawing the material pin, and back-off is divided into two sections, so that the width on back-off top is consistent with the width that draws material pin body, strengthened greatly the tensile strength of drawing material pin pull head, when pulling out stub bar, draw the material pin to be not easy to be broken, reduced production cost.
Description of drawings
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.
Fig. 1 is the structural representation that prior art is drawn the material pin;
Fig. 2 is the structural representation that draws the material pin of the embodiment of the invention.
The specific embodiment
Below in conjunction with accompanying drawing of the present invention, technical scheme of the present invention is clearly and completely described, obviously, described embodiment only is the present invention's part embodiment, rather than whole embodiment.Based on the embodiment among the present invention, those of ordinary skills belong to the scope of protection of the invention not making the every other embodiment that obtains under the creative work prerequisite.
As shown in Figure 2, a kind of material pin that draws that the embodiment of the invention provides comprises and draws material pin body 1, plunger 2; Described plunger is provided with back-off 3, and described back-off 3 is divided into two sections.
Described back-off 3 is divided into two sections, and whole back-off is Pear-Shaped.
The opening Breadth Maximum of described back-off 3 is consistent with the width that draws material pin body, is L.
The above; be the specific embodiment of the present invention only, but protection scope of the present invention is not limited to this, anyly is familiar with those skilled in the art in the technical scope that the present invention discloses; can expect easily changing or replacing, all should be encompassed within protection scope of the present invention.Therefore, protection scope of the present invention should be as the criterion by described protection domain with claim.
Claims (3)
