The invention relates to an inclined pin structure which is used for shaping products with a large area of barbs inside. The inclined pin structure comprises a core that is provided with a plurality of inclined pin holes; an inclined pin group that comprises one or a plurality of inclined pins one-to-one corresponding to the inclined pin holes, and each inclined pin comprises an inclined pin lever and an inclined pin insert that is inserted and fixed near to the top of the inclined pin lever and is movably arranged in the corresponding inclined pin hole by the respective inclined pin lever. Excellently, the bottom of one or a plurality of inclined pin inserts is provided with one or a plurality of positioning parts respectively, and the core is provided with one or a plurality of positioning holes correspondingly. By adopting the inclined pin structure and the inclined pin insert that is inserted and fixed on the inclined pin lever, and a corresponding shape for barb shaping of products is formed by the inclined pin group formed by piecing together the inclined pins, thus achieving the purpose of shaping the products with a large area of barbs inside easily.
Description
[technical field]
The relevant a kind of inclined pin structure of the present invention is meant a kind of inclined pin structure that there is the large tracts of land barb product inside that is applied to especially.
[background technology]
When producing plastic cement products, run into the situation that has overhead kick on the product through regular meeting.See also Fig. 1, it illustrates the inclined pin structure schematic perspective view into prior art.As shown in the figure, for there being barb 101 this situations on the product 100, if do not adopt inclined pin structure, then barb 101 can not break away from die (figure does not show) during die sinking, therefore can't be fully by die (figure does not show) moulding.And, then solved the problems referred to above so adopt simple one-body molded 200 pairs of barbs 101 of taper pin to do corresponding moulding because barb 101 is simple in structure and area is less.After the die sinking, product 100 directions of motion are consistent with the die sinking direction, and taper pin 200 is because the direction of motion and die sinking direction are angled, its movement travel can be decomposed into the die sinking direction stroke and with the stroke of the perpendicular direction of die sinking direction, when the movement travel of taper pin 200 and the perpendicular direction of die sinking direction is enough, 200 barbs 101 that break away from the product 100 of taper pin, the so convenient product 100 that takes out.
Yet for product inside complexity, product has the large tracts of land barb, and when the product barb partly was irregularly shaped, this simple taper pin form just can not satisfy.See also Fig. 2, it illustrates to the product schematic perspective view of large tracts of land barb is arranged.As shown in the figure, there is large tracts of land barb 10 in this product 1.If produce this product 1, adopt above-mentioned simple taper pin form just to be difficult to finish.
In view of this, be necessary to develop a kind of inclined pin structure in fact, this inclined pin structure is applied to the moulding that there is the product of large tracts of land barb inside, utilizes this inclined pin structure, then can finish the moulding that there is the product of large tracts of land barb inside easily.
[summary of the invention]
Therefore, the object of the present invention is to provide a kind of inclined pin structure, this inclined pin structure is applied to the moulding that there is the product of large tracts of land barb inside, utilizes this inclined pin structure, then can finish the moulding that there is the product of large tracts of land barb inside easily.
For reaching above-mentioned purpose, inclined pin structure of the present invention, this inclined pin structure is applied to the moulding that there is the product of large tracts of land barb inside, and this inclined pin structure comprises:
One male model benevolence which is provided with several taper pin holes;
One taper pin group, this taper pin group comprises one or several taper pins, these taper pins are corresponding one by one with above-mentioned taper pin hole, each taper pin comprises that respectively a taper pin bar and an edge establish and be fixed near near the taper pin mold insert the taper pin masthead end position, and each taper pin all is located in its corresponding taper pin hole by taper pin bar separately is movable.
Preferably, above-mentioned one or several taper pin mold inserts bottom are respectively equipped with one or several location divisions, and correspondence is provided with one or several locating holes on the male model benevolence, so can be when inclined pin return, by location division and accurate return of cooperating of locating hole.
Preferably, above-mentioned one or several taper pin bars are the T type, and these taper pin holes of answering for the taper pin pole pair of T type are the T type, so can make things convenient for the return of taper pin, eject.
Compared to prior art, inclined pin structure of the present invention, this inclined pin structure is applied to the moulding that there is the product of large tracts of land barb inside, utilize this inclined pin structure, establish fixedly taper pin mold insert by edge on the taper pin bar, taper pin group that these taper pins are combined into forms the pairing shape of product barb moulding, and is like this then can finish the moulding that there is the product of large tracts of land barb inside easily.
For purpose of the present invention, structural feature and function thereof are had further understanding, conjunction with figs. is described in detail as follows now:
