Abstract
The invention relates to a two-section angle pin that is applied to a mold. The two-section angle pin comprises: an angle pin seat, which is disposed in an upper ejector plate of the mold; a first section angle pin, one end of which is arranged on the angle pin seat and the other end of which is provided with a groove; a second section angle pin, which is mounted on the first section angle pin and provided with a stop pin, with one end of the stop pin located in the groove. For the two-section angle pin of the invention, when producing a product having an undercut at an inverse hook in the angle pin exit direction, the first section angle pin makes tilt movement to exit from the inverse hook of the product, and the second section angle pin makes vertical movement so as to make the two-section angle pin exit smoothly, thus finishing a demolding action.
Description
[technical field]
The present invention relates to a kind of taper pin, be specifically related to a kind of two-part taper pin.
[background technology]
When producing plastic cement products, the overhead kick and the less overhead kick of body of inboard generally adopt taper pin to withdraw from the plastic cement products, and when withdrawing from the product overhead kick, taper pin ejects the effect of product in addition, so taper pin is used on plastic mould widely.
Yet, when producing plastic cement products,, cause on the product overhead kick place taper pin exit axis and produce back-off sometimes because of the restriction of plastic cement products structure, see also shown in Figure 1ly, it illustrates the sketch map that the product of back-off is arranged on the taper pin exit axis.Because of product 10 is provided with back-off 12 on overhead kick 11 place's taper pin exit axis, taper pin can't withdraw from, and product can't 10 demouldings, causes the puzzlement of mould design.
In view of this, be necessary to develop a kind of novel two-part taper pin in fact, when on production overhead kick place taper pin exit axis, the product of back-off being arranged, this two-part taper pin can successfully withdraw from, and makes product stripping.
[summary of the invention]
Therefore, the purpose of this invention is to provide a kind of two-part taper pin, when this two-part taper pin has the product of back-off on production overhead kick place taper pin exit axis, can successfully withdraw from, make product stripping.
In order to achieve the above object, two-part taper pin of the present invention, it is applied in the mould, and this two-part taper pin comprises:
The taper pin seat, it is located in the upper ejector plate of above-mentioned mould;
First section taper pin, one of which end are located on the above-mentioned taper pin seat, and this first section taper pin other end is provided with groove;
Second section taper pin, it is located on above-mentioned first section taper pin, and this second section taper pin is provided with fixing pin, and this fixing pin one end is located in the above-mentioned groove.
Especially, above-mentioned second section taper pin also comprises the copper plug.
Especially, above-mentioned groove is a dovetail groove.
Compared to prior art, two-part taper pin of the present invention is when having the product of back-off on production overhead kick place taper pin exit axis; First section taper pin banking motion withdraws from the overhead kick of product; Second section taper pin moves both vertically, and this two-part taper pin is successfully withdrawed from, and accomplishes demoulding action.
[description of drawings]
Fig. 1 illustrates the sketch map that the product of back-off is arranged on the taper pin exit axis.
Fig. 2 illustrates the sketch map of two-part taper pin matched moulds state of the present invention.
Fig. 3 illustrates the sketch map of two-part taper pin die opening state of the present invention.
[specific embodiment]
See also shown in Figure 2ly, it illustrates the sketch map of two-part taper pin matched moulds state of the present invention.Two-part taper pin of the present invention, it is applied in the mould, and this two-part taper pin comprises:
Taper pin seat 400, it is located in the upper ejector plate 40 of above-mentioned mould;
First section taper pin 300, one of which end are located on the above-mentioned taper pin seat 400, and the other end is provided with groove 310, and in present embodiment, this groove 310 is a dovetail groove;
Second section taper pin 200; It is located on above-mentioned first section taper pin 300, and this second section taper pin 200 is provided with fixing pin 210, and these fixing pin 210 1 ends are located in the above-mentioned groove 310; And when mould matched moulds state; This fixing pin 210 and above-mentioned groove 310 1 contacts side surfaces, this second section taper pin 200 also comprises copper plug 220, this copper plug 220 is used to stop above-mentioned fixing pin 200.
See also shown in Figure 3ly, it illustrates the sketch map of two-part taper pin die opening state of the present invention.During the mould die sinking, male model plate 30 was opened with caster in 20 minutes, and the ejecting mechanism of mould moves upward; Upper ejector plate 40 moves upward, and taper pin seat 400 these the first section taper pin 300 of drive that are fixed in this upper ejector plate 40 move together, because first section taper pin 300 has gradient; It is along first section taper pin 300 gradient direction move (direction shown in first section taper pin place arrow); This first section taper pin 300 is when moving upward, and the overhead kick 11 of product 10 is withdrawed from motion backward, and the fixing pin 210 in while second section taper pin 200 is movable in above-mentioned groove 310; Make second section taper pin 200 move vertically upward (direction shown in second section taper pin place arrow); Make product 10 demouldings with this, and make back-off 12 demouldings of product 10, accomplish demoulding action.
