Abstract

The invention discloses a mould angle pin structure and a mould with the structure. The mould angle pin structure comprises a cavity and an angle-pin hole, wherein the cavity and the angle-pin hole are in the mould, and the cavity is matched with a product to be processed. An angle pin slides and penetrates through the angle-pin hole. One side of the tail end of the angle pin is matched with the cavity, and a template in the other side is provided with a vertical surface. A gap is formed between the vertical surface and the angle pin. An ejector pin slides and penetrates through the angle pin. An end of the ejector pin is abutted against the cavity and the other end of the ejector pin is abutted against the vertical surface. A spring applying acting force towards the template on the ejector pin is disposed in the angle pin. The invention also provides the mould. The mould angle pin structure is simple in structure and has characteristics of capability of avoiding product strain and deformation caused by pulling, capability of reducing generation of defective products, and capability of reducing waste. The mould angle pin structure needs large space so that the structure is suitable for large-scale moulds.

Die pitched roof structure according to the present invention is by thimble is set, and the one end on pin top is vertical plane, and during die sinking, oblique top is up moved along angle, pin withstands under the effect of vertical plane, with respect to (towards the die cavity) motion forward of pin top, play and withstand all the time product, oblique top is separated with product.Hence one can see that, and die pitched roof structure of the present invention is simple in structure, has and effectively avoid product to pull, be pulled out of shape, can greatly reduce the generation of defective products, the feature cutting the waste.The present invention is larger because of needs space, is applicable to large mold.
In addition, die pitched roof structure according to the present invention also has following additional technical feature:
Preferably, described die cavity is located between mother module core and male die core, and described inclined top hole is located on described male die core.
Preferably, in described oblique top, be provided with spring groove, described thimble is provided with Ka Tai, and described spring is located between described spring groove and Ka Tai.
Preferably, described Ka Tai is provided with cover plate outward, and described thimble slides through described cover plate.
Preferably, described template is provided with arc surface above vertical plane.
The present invention proposes a kind of mould on the other hand, and it has above-mentioned die pitched roof structure.
Mould of the present invention, owing to possessing this mould mould item structure, effectively avoids product to pull, be pulled out of shape, can greatly reduce the generation of defective products, the feature cutting the waste therefore have.
Additional aspect of the present invention and advantage in the following description part provide, and part will become obviously from the following description, or recognize by practice of the present invention.

Fig. 2 is the structural representation state a of die pitched roof structure of the present invention;
Fig. 3 is the structural representation state b of die pitched roof structure of the present invention;
Fig. 4 is the structural representation state c of die pitched roof structure of the present invention.
description of reference numerals:
Mother module core 1; Male die core 2; Die cavity 3; Oblique top 4; Thimble 5; Spring 6.
The specific embodiment
Describe embodiments of the invention below in detail, the example of described embodiment is shown in the drawings, and wherein same or similar label represents same or similar element or has the element of identical or similar functions from start to finish.Below by the embodiment being described with reference to the drawings, be exemplary, only for explaining the present invention, and can not be interpreted as limitation of the present invention.
In description of the invention, unless otherwise prescribed and limit, it should be noted that, term " installation ", " being connected ", " connection " should be interpreted broadly, for example, can be mechanical connection or electrical connection, can be also the connection of two element internals, can be to be directly connected, also can indirectly be connected by intermediary.For the ordinary skill in the art, can understand as the case may be the concrete meaning of above-mentioned term.
Below with reference to Fig. 2,3,4, describe according to a kind of die pitched roof structure of the embodiment of the present invention.As in Figure 2-4, die pitched roof structure of the present invention comprises mother module core 1, male die core 2, die cavity 3, oblique top 4, thimble 5 and spring 6.
Male die core 2 is located at the below of mother module core 1, forms the die cavity 3 adapting with processed product between mother module core 1 and male die core 2.Male die core 2 is provided with inclined top hole, has slid through oblique top 4 in inclined top hole, and matches with described die cavity 3 on the left of the upper end of this oblique top 4, and opposite side is male die core 2, and male die core 2 is provided with vertical plane, shape space between this vertical plane and described oblique top 4; In described oblique top 4, slid through thimble 5, described thimble 5 one end are mounted on described die cavity 3, and the other end is mounted on described vertical plane, in described oblique top 4, is also provided with described thimble 5 is applied to the spring 6 towards the active force of template.
Die pitched roof structure according to the present invention is by thimble 5 is set, and the one end on pin top is vertical plane, and during die sinking, oblique top 4 is up moved along angle, pin withstands under the effect of vertical plane, with respect to (towards the die cavity 3) motion forward of pin top, play and withstand all the time product, 4 of oblique tops are separated with product.Hence one can see that, and die pitched roof structure of the present invention is simple in structure, has and effectively avoid product to pull, be pulled out of shape, can greatly reduce the generation of defective products, the feature cutting the waste.The present invention is larger because of needs space, is applicable to large mold.
In described oblique top 4, be provided with spring groove, described thimble 5 is provided with Ka Tai, and described spring 6 is located between described spring groove and Ka Tai.Thus, can make the installation of spring 6 more reasonable, be conducive to save space.
Described Ka Tai is provided with cover plate outward, and described thimble 5 slides through described cover plate.Cover plate is bolted in oblique top 4.Hence one can see that, and cover plate makes the easier for installation of spring 6 and oblique top 4.
In addition, as preferred exemplary of the present invention, described template is provided with arc surface above vertical plane.Described arc surface bends towards male die core 2 one sides.Like this, can be can be when die sinking thimble 5 return rapidly, in order to avoid the left end of thimble 5 damage product, oblique top 4 return smoothly while simultaneously guaranteeing matched moulds.
Operation principle, Fig. 2-Fig. 4 has shown the process of this ramp-roof structure die sinking.
(1) Fig. 2 is matched moulds state;
(2) Fig. 3 is oblique top 4 while ejecting, and thimble 5 withstands finished product all the time, and oblique top 4 is separated with finished product;
(3) Fig. 4 is after oblique top 4 ejects, and thimble 5 separates completely with oblique top 4 and finished product.
Wherein: the value principle of A size: when oblique top 4 ejects A stroke, finished product completes and separates with oblique top 4.
It is excessive that B place is shaped as circular arc, thimble 5 return smoothly while guaranteeing oblique top 4 matched moulds.
The embodiment of the present invention also proposes a kind of mould, and it has above-mentioned die pitched roof structure.Mould of the present invention, owing to possessing this mould mould item structure, effectively avoids product to pull, be pulled out of shape, can greatly reduce the generation of defective products, the feature cutting the waste therefore have.
