Abstract

The utility model discloses a dual-oblique-pin mechanism, which is used for producing a product, wherein the product includes a clamping hook and an inverted fastener which is in parallel or approximately in parallel with the clamping hook. The dual-oblique-pin mechanism comprises a first oblique pin and a second oblique pin, wherein the first oblique pin is provided with an oblique pin clamping hook and the shape of the oblique pin clamping hook is matched with the shape of the clamping hook of the product; and the top end of the second oblique pin is provided with an extension part which extends towards the first oblique pin, the bottom surface of the extension part is in contact with the top surface of the first oblique pin, and the top surface of the extension part is in contact with the bottom surface of the inverted fastener of the product. Compared with the prior art, when the product is ejected out, since the top surface of the first oblique pin and the bottom surface of the extension part of the second oblique pin slide relatively, the oblique pin clamping hook of the first oblique pin can be withdrawn from the clamping hook of the product. Finally, the product is taken out from the second oblique pin. Therefore, the situation that a mold cannot be opened because the top surface of the oblique pin and the inverted fastener of the product interfere with each other is avoided.

Description

The diclinic pin mechanism

[technical field]

The utility model relates to a kind of diclinic pin mechanism, particularly relates to a kind of diclinic pin mechanism that withdraws from after the die sinking that makes things convenient for.

[background technology]

In process, run into the situation that not only has grab but also have back-off sometimes to plastic cement products.See also Fig. 1, Fig. 1 illustrates the structural representation into a kind of plastic cement products.These product 10 at least one ends extensions are provided with grab 11, and have back-off 12 with these grab 11 parallel or substantially parallel directions.

Please consult Fig. 2, Fig. 2 illustrates the taper pin mechanism into prior art.This taper pin 20 has the taper pin grab 21 that cooperates above-mentioned grab 11 moulding, and the end face 22 of this taper pin 20 cooperates back-off 12 moulding of said product 10.Yet; When adopting this taper pin mechanism to produce product 10, owing to withdraw from the taper pin grab 21 of taper pin 20 on the exit axis of grab 11 of product 10, the end face 22 of taper pin 20 exists with the back-off of product 10 12 and interferes; And cause taper pin 20 to withdraw from, thereby can't die sinking.

In view of this, be necessary to develop a kind of diclinic pin mechanism in fact, to address the above problem.

[summary of the invention]

Therefore, the purpose of the utility model provides a kind of diclinic pin mechanism, both makes the product that can moulding has grab and the back-off parallel with grab, again can be so that taper pin normally withdraws from.

In order to achieve the above object, the diclinic pin mechanism that the utility model provides is used to produce product, said product comprise grab and with the parallel or substantially parallel back-off of grab, this diclinic pin mechanism comprises:

First taper pin, it has the taper pin grab, and said taper pin grab is shaped as the grab shape that cooperates said product;

Second taper pin, its top have the extension of extension to said first taper pin, and the bottom surface of said extension contacts with the end face of said first taper pin, and the end face of said extension contacts with the bottom surface of the back-off of said product.

Optional, said first taper pin and vertical direction are an angle, and said second taper pin is parallel with vertical direction.

Optional, the said second taper pin bottom is connected with the taper pin push rod.

Compared to prior art; Utilize the diclinic pin mechanism of the utility model; Because when ejecting, relative slip is done in the bottom surface of the extension of the end face of said first taper pin and said second taper pin, thereby the taper pin grab of said first taper pin withdraws from the grab of said product.Take out product from said second taper pin at last.Like this then can not cause the back-off of taper pin end face and product to interfere and situation that can't die sinking.

[specific embodiment]

Please consult Fig. 1, Fig. 3 jointly, Fig. 3 is the structural representation of the utility model diclinic pin mechanism one preferred embodiment at the matched moulds state.

The mould that this diclinic pin mechanism is applied to comprises upper mounted plate 100, caster 101, mother module core 102, male model benevolence 103, male model plate 104, upper plate 105, lower roof plate 106, the bottom plate of setting up in regular turn 107 and is located at said male model plate 104 and the foot pad 108 of 107 of said bottom plates.

In order to achieve the above object, the diclinic pin mechanism that the utility model provides is used to produce product 10, said product 10 comprise grab 11 and with the parallel or substantially parallel back-off 12 of grab 11, this diclinic pin mechanism comprises:

First taper pin 109, it has taper pin grab 110, and said taper pin grab 110 is shaped as grab 11 shapes that cooperate said product 10;

Second taper pin 111, its top have the extension 112 of extension to said first taper pin 109, and the bottom surface of said extension 112 contacts with the end face of said first taper pin 109, and the end face of said extension 112 contacts with the bottom surface of the back-off 12 of said product 10.

Wherein, said first taper pin 109 is an angle with vertical direction, and said second taper pin 111 is parallel with vertical direction.

In present embodiment, said second taper pin 111 bottoms are connected with taper pin push rod 113, said taper pin push rod 113.Said lower roof plate 106 is fixed in said first taper pin 109 and said taper pin push rod 113 bottoms.Said first taper pin 109 is arranged in male model benevolence 103, male model plate 104, upper plate 105, and is said; Said second taper pin 111 is located at said male model benevolence 103, and said taper pin push rod 113 is arranged in male model plate 104, upper plate 105.

Please consult Fig. 4, Fig. 5, Fig. 4 is the structural representation of the utility model diclinic pin mechanism one preferred embodiment at the state of ejecting for one preferred embodiment of the utility model diclinic pin mechanism at structural representation, Fig. 5 of die opening state.

When die sinking, said first taper pin 109, said second taper pin 111 and said product 10 are stayed in the male model together.When ejecting product 10; Said first taper pin 109, said second taper pin 111 are done together and are ejected action; Because said first taper pin 109 and vertical direction are at an angle; Therefore it has a componental movement in the horizontal direction, thereby relative slip is done in the bottom surface of the extension 112 of the end face of said first taper pin 109 and said second taper pin 111, and the taper pin grab 110 of said first taper pin 109 withdraws from the grab 11 of said product 10.Take out product 10 from said second taper pin 111 at last.

Compared to prior art; Utilize the diclinic pin mechanism of the utility model; Because when ejecting; Relative slip is done in the bottom surface of the extension 112 of the end face of said first taper pin 109 and said second taper pin 111, thereby the taper pin grab 110 of said first taper pin 109 withdraws from the grab 11 of said product 10.Take out product 10 from said second taper pin 111 at last.Like this then can not cause the back-off 12 of taper pin end face and product 10 to interfere and situation that can't die sinking.

Be pointed out that the utility model is not limited to above-mentioned embodiment, any simple modification, equivalent variations and modification that any professional and technical personnel of being familiar with does the foregoing description based on technical scheme of the present invention all fall in the protection domain of the utility model.
