Description
Technical field
The present invention relates to the depanning accessory of mould, a kind of ejecting structure of plastic mould is specifically referred to.
Background technology
Injection moulding is to inject the plastic material for heating state in the closed die cavity in mould with required shape at a high speed, is treated
Plastic material is cooled and solidified, and is opened mould and is ejected the plastic cement products of solidification, the processing method to obtain shaped article.Due to note
Modeling method for processing forming has low shaping expense, short molding cycle, forming process simple and is easy to the complicated plastic cement of forming shape
The features such as product, therefore in plastic cement products application field using extremely wide.
Injection mold is one of important method of plastic rubber shaping, when interiors of products has back-off, is generally taken out using oblique top
Core mechanism is so that product is smoothly stripped.Among mold design, when run into need to use at present using ramp-roof structure by the way of master
All to develop from following two structure types：A kind of structure type is as shown in figure 1, the ejecting mechanism among mould is sharp
Designed at an angle with the ejection direction of mould with inclined plane principle, i.e. pitched roof mechanism, when oblique top 1 is outwards pushed out, due to
Inclined-plane 2 is acted on, and oblique top 1 can produce the displacement of certain level or other angle directions simultaneously, so as to realize the de- of product back-off
From；Second of structure type as shown in Figure 2 and Figure 3, the characteristic having in itself using spring steel, when mould is in matched moulds state
When, the oblique top that spring steel 3 is made is in restrained state, the generation product back-off feature of oblique top 1 now；When oblique top 1 is released,
Constraint suffered by spring steel 3 is released, and the back-off of product is deviate from from mould.
However, to be required to design space larger for above two structure type, some products are caused not apply to, and to oblique top
The abrasion of surrounding mould meat is larger, influences the long lifespan of mould, and requirement reduction (especially second structure to die steel
Form).
The content of the invention
The purpose of the present invention be overcome weak point of the prior art there is provided the simple in construction, applicability of one kind it is wide, to oblique
