Abstract
The utility model discloses a cover half tunnel structure of loosing core for die casting, it includes that hydro -cylinder, take -up housing and tunnel loose core, the outside at the cover half frame is fixed to the hydro -cylinder, the output shaft of hydro -cylinder is connected with the take -up housing, take -up housing swing joint is on the cover half frame, the one end of loosing core in the tunnel is connected with the take -up housing, and the other end passes in the die cavity that cover half benevolence stretched into the mould. Adopt the utility model provides a cover half tunnel structure of loosing core can make the concave station shaping department outward appearance of product level, can not produce appearance imperfections such as the compound die is disconnected poor, burr for the overall structure of mould is simple, and the preparation is convenient, and the mould that opens and shuts operation is reliable.
Description
Technical field
The utility model relates to a kind of cover half tunnel loose core structure for die casting, belongs to die casting technical field.
Background technology
Complicated due to die-cast product structure, usually needs to arrange cover half tunnel loose core structure and helps die sinking.And the actuator of traditional cover half tunnel loose core structure is arranged in mould, so that mold integral complex structure, be difficult to processing and fabricating; In addition, because the slide block for tunnel loose core is all arranged at rear mold usually, after die sinking, easily there is the open defects such as matched moulds offset, burr in the shaping place of concave station of product, needs to carry out secondary operations, not only waste time and energy, and add production cost.
Utility model content
For the problems referred to above that prior art exists, the purpose of this utility model is to provide a kind of cover half tunnel loose core structure for die casting, causes product appearance defect to avoid loosing core.
For achieving the above object, the utility model adopts following technical scheme:
A kind of cover half tunnel loose core structure for die casting, comprise oil cylinder, take-up housing and tunnel loose core, described oil cylinder is fixed on the outside of cover half frame, the output shaft of described oil cylinder is connected with take-up housing, described take-up housing is movably connected on cover half frame, one end of described tunnel loose core is connected with take-up housing, and the other end stretches in the die cavity of mould through fixed mold core.
As a kind of embodiment, described oil cylinder is fixed on the outside of cover half frame by oil cylinder fixing base.
As a kind of embodiment, the output shaft of described oil cylinder is connected by dovetail groove with between take-up housing.
As a kind of embodiment, described tunnel loose core is connected by dovetail groove with between take-up housing.
Compared to prior art, Advantageous Effects of the present utility model is:
The cover half tunnel loose core structure provided due to the utility model adopts external loose core of oil cylinder shaping, therefore there is unitary mould structure simple, be convenient to advantages such as making, operation of loosing core is reliable, can effectively avoid die-cast product to occur the open defects such as matched moulds offset, burr having very strong practicality.
Accompanying drawing explanation
The schematic diagram of a kind of cover half tunnel loose core structure for die casting that Fig. 1 provides for the utility model.
Number in the figure is schematically as follows: 1-oil cylinder; 11-output shaft; 2-take-up housing; 21-dovetail groove; 3-tunnel loose core; 4-cover half frame; 5-fixed mold core; 6-oil cylinder fixing base.
Detailed description of the invention
Below in conjunction with the drawings and specific embodiments, the technical solution of the utility model is described in further detail.
Embodiment
As shown in Figure 1: a kind of cover half tunnel loose core structure for die casting that the present embodiment provides, comprise oil cylinder 1, take-up housing 2 and tunnel loose core 3, described oil cylinder 1 is fixed on the outside of cover half frame 4, the output shaft 11 of described oil cylinder 1 is connected with take-up housing 2, described take-up housing 2 is movably connected on cover half frame 4, one end of described tunnel loose core 3 is connected with take-up housing 2, and the other end stretches in the die cavity of mould through fixed mold core 5.
Described oil cylinder 1 is fixed on the outside of cover half frame 4 by oil cylinder fixing base 6.The output shaft 11 of described oil cylinder 1 is connected by dovetail groove 21 with between take-up housing 2.Described tunnel loose core 3 is also connected by dovetail groove with between take-up housing 2.
When die sinking, twitch take-up housing 2 to take tunnel loose core 3 out of by external oil cylinder 1, tunnel loose core 3 and product are departed from, thus realizes the demoulding of product.When matched moulds, take-up housing 2 and tunnel loose core 3 reset by oil cylinder 1.The cover half tunnel loose core structure adopting the utility model to provide, can make the concave station of product shaping place flat appearance, can not produce the open defects such as matched moulds offset, burr.In addition, because oil cylinder 1 is arranged on the outside of cover half frame 4, make the overall structure of mould simple, easy to make, folding modulo operation is reliable.
Finally be necessary to herein means out: the foregoing is only the utility model preferably detailed description of the invention; but protection domain of the present utility model is not limited thereto; anyly be familiar with those skilled in the art in the technical scope that the utility model discloses; the change that can expect easily or replacement, all should be encompassed within protection domain of the present utility model.
