Abstract

The utility model discloses a novel oblique pin structure, which comprises a male die and a female die capable of opening and closing, wherein, the molding space is arranged between the male die and the female die. Furthermore, the male die is provided with a communicated oblique pin. One end of the oblique pin is provided a bending portion for extending into molding space to form the bending part of molding product. The bending portion connected with the oblique pin is a smooth transitionary arc plane, which make the stress not concentrate on the bending portion in molding products by the oblique pin. The utility model has a simple structure and reduces the break of the oblique pin.

Description

A kind of inclined pin structure
Technical field
The utility model relates to a kind of mould structure, particularly relates to a kind of inclined pin structure.
Background technology
When utilizing mould-forming process to make plastic product, need to utilize the mould structure of making in advance, and the plastics of fusion are injected among the mould to reach the purpose of shaped article by injection machine.
As shown in Figure 1, be the side view of inclined pin structure in the existing mold.This taper pin 10 comprises a taper pin post 101 and a kink 102 that links to each other with this taper pin post 101 1 ends bending, this kink 102 is in order to participate in shaped article, and itself and this taper pin post 101 connecting places form a bending angle, because this bending angle is a right angle, cause when formed product ejects, stress concentrates on this bending angle, makes this place that the situation of fracture take place easily.
Summary of the invention
In view of the above problems, the utility model has disclosed a kind of novel inclined pin structure, and this inclined pin structure is simple, and is difficult for taking place the situation of taper pin fracture.
For reaching above-mentioned purpose, the utility model has adopted following technical scheme: a kind of inclined pin structure, this structure is mainly used in the mould that comprises a male model and a master mold, but this male model and this master mold is oppositely arranged and folding, and reserve the space of a shaped article between this male model and this master mold, in addition, also be penetrated with a taper pin on this male model, this taper pin one end bends out a kink, this kink is stretched and is placed this molding space and participate in shaped article, and the bending place that this kink links to each other with this taper pin forms a bending angle, and this bending angle is made as a cambered surface.
Preferable, the utility model also provides a kind of inclined pin structure, and wherein, this cambered surface can be 45 ℃ of angles of a slyness or is a R angle cambered surface, and so, when product ejected moulding, stress was difficult for concentrating on herein.
Above-mentioned technical scheme provides a kind of novel inclined pin structure, and this inclined pin structure is simple, and when product ejected moulding, stress was difficult for concentrating on the bending place, reduces the situation that the taper pin fracture takes place in process of production, has guaranteed the intensity of taper pin.

The specific embodiment
See also Fig. 2 and shown in Figure 3, be side view of the present utility model and constitutional diagram.Wherein, the utility model is mainly used in the mould with male model part and master mold part, this master mold part mainly comprises a caster 20, be combined with a mother module core 201 on it, but this caster 20 is oppositely arranged and folding with the male model plate 30 of this male model part, and set in advance effigurate molding space between this caster 20 and this male model plate 30, it utilizes an injection machine (not shown) that the plastics of fusion are injected in this molding space, can mold the product consistent with this molding space shape 40.
In addition, this male model plate 30 is away from a side and a upper ejector plate 304 adjacent settings of this caster 20, and this upper ejector plate 304 and liftout plate once 305 be adjacent lays equal stress on to stack and puts, on these, following liftout plate 304 and 305 is provided with a taper pin seat 303, in addition, run through in this male model plate 30 and be provided with a strip taper pin 302, fixedly connected this taper pin seat 303 of these taper pin 302 1 terminal 3022 usefulness screws, its another end bends out a kink 3021, this kink 3021 is stretched and is placed in the above-mentioned molding space, participate in shaped article 40 directly, and this kink 3021 forms a bending angle 3023 with these taper pin 302 connecting places, and this bending angle 3023 can be the cambered surface of rounding off, as a R angle or a C angle cambered surface, in the present embodiment, this bending angle 3023 is a R angle cambered surface, and so, the R angle or the C angle of this rounding off can be when product eject, stress is difficult for concentrating on this bending angle 3023 places, has guaranteed the intensity of this taper pin 302.
After the dispensing end (not shown) of make-up machine is filled molding space, it is formable products 40, in the die sinking process, at first male and female template 30 and 20 is opened certain space, these upper and lower liftout plates 304 and 305 move upward, thereby the kink 3021 that drives this taper pin 302 moves to the direction that withdraws from shaped article 40, at this moment, stress is difficult for concentrating on this bending angle 3023 places, has reduced the situation of taper pin 302 fractures; When mould once more during matched moulds, before contacting, male and female template 30 and 20 touches caster 20 earlier by the release link (not shown) that is loaded in the mould structure on upper and lower liftout plate 304 and 305 earlier, promote upper and lower liftout plate 304 and 305 move downward reach return after, thereby make mould be in the matched moulds state once more.

Claims (2)

1. inclined pin structure, this structure is mainly used in the mould that comprises a male model and a master mold, but this male model and this master mold is oppositely arranged and folding, and reserve the space of a shaped article between this male model and this master mold, in addition, also be penetrated with a taper pin on this male model, this taper pin one end bends out a kink, and this kink is stretched and placed this molding space and participate in shaped article, and forms a bending angle between this kink and this taper pin, it is characterized in that this bending angle is made as a cambered surface.
2. inclined pin structure according to claim 1 is characterized in that, this cambered surface can be a C angle of rounding off or is the cambered surface at a R angle.
