Abstract
The utility model discloses the hot mouth protection mechanism of a kind of hot runner mould, the lastics plate comprising cover half He match, and cover half is provided with the hot mouth be connected with hot flow path, is provided with protective jacket crashes for directly contacting with lastics plate during matched moulds in all sides of hot mouth.Protective jacket in hot mouth portion is formed and draws material end for pulling out cold runner stub bar during die sinking.The utility model also has the function of drawing material pin simultaneously at the hot mouth of available protecting, meet mould structure requirement, have structure simple, save space, assemble simple advantage.
Description
Technical field
The utility model discloses the hot mouth protection mechanism of a kind of hot runner mould, divides belong to technology of die manufacturing field by International Patent Classification (IPC) (IPC).
Background technology
Present mould uses TOP-TIP to get more and more, some shape of product is little, but need multiple spot to enter glue, in order to cost-saving, the hot mouth of single-point will be done and turn cold runner multi-point adhesive mouth, hot mouth will inevitably and lastics plate between produce and crash, easily damage, and the close together put between glue mouth runner and hot mouth, cannot make the smooth demoulding of cold runner with drawing material pin.
Summary of the invention
For the deficiencies in the prior art, the utility model provides the hot mouth protection mechanism of a kind of hot runner mould, by increasing protective jacket on hot mouth, increases the service life of hot mouth.
For achieving the above object, the utility model is achieved through the following technical solutions:
The hot mouth protection mechanism of a kind of hot runner mould, the lastics plate comprising cover half He match, cover half is provided with the hot mouth be connected with hot flow path, is provided with protective jacket crashes for directly contacting with lastics plate during matched moulds in all sides of hot mouth.
Further, described protective jacket is coated with hot mouth and is fixed as one, and the protective jacket in hot mouth portion is formed and draws material end for pulling out cold runner stub bar during die sinking.
Further, the material end that draws of described protective jacket is provided with overhead structure to pull out cold runner stub bar.
The utility model is on hot mouth, add protective jacket La Liao mechanism; cold runner stub bar is pulled out when die sinking; hot mouth is protected during matched moulds; avoid directly contacting with lastics plate crashing; the utility model also has the function of drawing material pin simultaneously at the hot mouth of available protecting; meet mould structure requirement, have structure simple, save space, assemble simple advantage.
Accompanying drawing explanation
Fig. 1 is the utility model matched moulds view.
Fig. 2 is the utility model die sinking pull-out stub bar schematic diagram.
Fig. 3 is the whole die opening state schematic diagram of the utility model.
Detailed description of the invention
Below in conjunction with accompanying drawing, the utility model is described in further detail:
Embodiment: refer to Fig. 1 to Fig. 3, the hot mouth protection mechanism of a kind of hot runner mould, the lastics plate 2 comprising cover half 1 and match, cover half 1 is provided with the hot mouth 3 be connected with hot flow path, is provided with protective jacket 4 crashes for directly contacting with lastics plate 2 during matched moulds in hot mouth 3 weeks sides.Protective jacket 4 is coated with hot mouth 3 and is fixed as one, and the protective jacket in hot mouth portion is formed and draws material end 41 for pulling out the stub bar of cold runner 5 during die sinking.The material end that draws of protective jacket is provided with overhead structure to pull out cold runner stub bar, is cast gate 50 in cold runner bottom.
The utility model general principle:
As Fig. 1 to Fig. 3, together with hot mouth protective jacket is fixing with hot mouth, during die sinking, the La Liao mechanism pull-out spot pouring mouth cold runner stub bar of protective jacket makes its smooth demoulding, during matched moulds, protective jacket directly contacts with lastics plate and crashes, hot mouth reaches protective action with contactless the crashing of lastics plate in protective jacket, strengthens the life-span of hot mouth.
The utility model, through accurate Calculation, design, utilizes the effect of hot mouth protective jacket La Liao mechanism, the hot mouth of effective protection, and has the function of drawing material pin, meets mould structure requirement.Have structure simple, save space, assemble simple advantage, have very large promotion prospect.
Above, be only the embodiment utilizing this origination techniques content, the modification that any those skilled in the art use this creation to do, change, all belong to the scope of the claims that this creation is advocated, and be not limited to those disclosed embodiments.
