Trace generates easy to crack（Intensity is insufficient）Influenced with weld mark it is beautiful, cause largely to waste and can not consign to client carry out using
Be sold to market.Have dealer by change into pour a position, forming temperature, mold temperature and increase the countermeasures such as die venting come into
Row adjustment, can weaken obvious degree or the position of weld mark, but be most still embodied on product ontology, and different degrees of influence produces
The appearance and intensity function of product.
Utility model content
The technical problems to be solved in the utility model is host front cover there are stress concentration region and the position is easy cracking, mentions
For a kind of novel mould structure for self-service breathing apparatus host front cover.
In order to realize the purpose, the technical solution of the utility model is as follows：One kind is for before self-service breathing apparatus host
The mould structure of lid, is made of front cavity and rear cavity, before the front cavity is provided commonly for molding main-machine with the rear cavity
Lid, the host front cover have planar portions and bending part, there is function setting area and evaporator area, institute is arranged in the planar portions
It states and is formed with top notch on bending part, evaporator setting area is adjacent to the top notch, and the bending part is in described
The region in top notch and evaporator setting section constitutes stress concentration region, and the type chamber in the rear cavity, which has, to be corresponded to
The function setting zone type cavity portion in function setting area, corresponding to evaporator setting area evaporator setting zone type cavity portion and
Stress concentration region type cavity portion corresponding to the stress concentration region.It is arranged to be formed in area in the evaporator in the rear cavity and draws
Flow pattern cavity portion, the conduction type cavity portion is adjacent to stress concentration region type cavity portion and the two is connected, so that injection material is most
It terminates in the conduction type cavity portion.
As a kind of preferred embodiment of mould structure for self-service breathing apparatus host front cover, the conduction type cavity portion by
Annular groove section and straight-line groove section composition, the straight-line groove section is for connecting the stress concentration region and the annular groove section.
As a kind of preferred embodiment of mould structure for self-service breathing apparatus host front cover, area is arranged in the evaporator
For square through hole.
Compared with prior art, the beneficial effects of the utility model at least that：The design of conduction type cavity portion penetrates injection molding
Forming end position is shifted out, is transferred to increased conduction type cavity portion from stress concentration region type cavity portion.Stress end and molten
Lapping defect is transferred on the molding non-functional muscle in conduction type cavity portion, then removes this non-functional muscle with mach mode, makes it
Meet the intensity and appearance requirement of product.
In addition to the utility model described above solve the technical issues of, constitute technical solution technical characteristic and by
Except beneficial effect brought by the technical characteristic of these technical solutions, other technologies problem that the utility model can solve,
The other technical characteristics for including in technical solution and these technical characteristic bring beneficial effects, will make in conjunction with attached drawing into one
Step detailed description.
Detailed description of the invention
Fig. 1 is the main view of host front cover in the prior art.
Fig. 2 is the side view of host front cover in the prior art.
Fig. 3 is the structural schematic diagram of an embodiment of the present invention.
Fig. 4 is the main view of host front cover in an embodiment of the present invention.
Specific embodiment
The utility model is described in further detail below by specific embodiment combination attached drawing.It needs herein
It is bright, the explanation of these embodiments is used to help to understand the utility model, but do not constitute the limit to the utility model
It is fixed.In addition, as long as technical characteristic involved in the various embodiments of the present invention described below is each other not
Constituting conflict can be combined with each other.
Fig. 3 and 4 are referred to, a kind of mould structure for self-service breathing apparatus host front cover is shown in the figure.For
The mould structure of self-service breathing apparatus host front cover 1.The host front cover 1 has planar portions 11 and bending part 12.The plane
There is function setting area 111 and evaporator area 112 is arranged in portion 11（In the present embodiment, square through hole）.On the bending part 12
It is formed with top notch 121.Evaporator setting area 112 is adjacent to the top notch 121.The bending part 12 is in described
Region between top notch 121 and evaporator setting area 112 constitutes stress concentration region 122.
Forming die structure is made of front cavity and rear cavity 2.The front cavity is provided commonly for forming with the rear cavity
Host front cover 1.
Relative to existing mould structure, the structure of the front cavity does not have any variation, and the structure of the rear cavity
There is difference.Rear cavity part same as the prior art：Type chamber in the rear cavity has to be set corresponding to the function
Set area 111 function setting zone type cavity portion 21, corresponding to the evaporator setting area 112 evaporator setting zone type cavity portion 22 and
