Abstract
The utility model discloses a reverse pushing mechanism for a fixed die of a die-casting die. The reverse pushing mechanism comprises a push plate, wherein one end of the push plate is fixedly connected with a fixed plate, a push rod and a return rod are fixedly arranged on the fixed rod, the push rod penetrates through the die, the return rod penetrates through the fixed die, and an elastic device for pushing the push plate and the fixed plate to move is arranged at the upper end of the push plate. The reverse pushing mechanism disclosed by the utility model can prevent local wrapping force of the fixed die from being larger than the wrapping force of a moving die during die-casting processing, thereby preventing the deformation problem of a product.
Description
Technical field
The utility model relates to field of die casting machines, more specifically, designs a kind of compression mod cover half thrust reverser mechanism.
Background technology
Because various automobile fitting diecast parts mechanism is complicated, during die-casting process since the local Bao Li of cover half greater than the Bao Li of dynamic model, workpiece is adsorbed on this part easily when the demoulding, thereby produces the product distortion, therefore is necessary prior art is improved.
Summary of the invention
In order to overcome the deficiency that prior art exists, the utility model provides a kind of compression mod cover half thrust reverser mechanism, when effectively having avoided die-casting process because local Bao Li greater than dynamic model, produces the problem of product distortion.
In order to solve the problems of the technologies described above; The utility model is able to solve through following technical proposals: compression mod cover half thrust reverser mechanism, comprise push pedal, and an end of said push pedal is fixedly connected with fixed head; Be set with push rod and release link on the said fixed head; Said push rod connects mould, and said release link connects cover half, is provided with the elastic device that promotion push pedal and fixed head move on the said push pedal.
In the technique scheme, preferred, described elastic device is a spring.
In the technique scheme, preferred, described spring is provided with a plurality of, and evenly distributes.
The utility model compared with prior art; Has following beneficial effect: when the mould die sinking; Make foundry goods can stick on the dynamic model through push rod; When having avoided die-casting process because cover half part Bao Li is greater than the Bao Li of dynamic model, and workpiece is adsorbed on this part easily when the demoulding, thereby produces the problem of product distortion.
Description of drawings
Fig. 1 is the structural representation of the utility model.
The specific embodiment
Below in conjunction with the accompanying drawing and the specific embodiment the utility model is described in further detail: referring to Fig. 1, compression mod cover half thrust reverser mechanism comprises push pedal 1; One end of said push pedal 1 is fixedly connected with fixed head 2; Be set with push rod 5 and release link 3 on the said fixed head 2, said push rod 5 connects mould 7, when mould is installed; Described push rod 5 contacts with foundry goods; Said release link connects cover half 10, and said push pedal 1 upper end is provided with and promotes the elastic device 4 that push pedal 1 and fixed head 2 move, and the elastic device that uses in the present embodiment is spring.
Do detailed description in the face of concrete principle down: the state that Fig. 1 carries out die casting when being the utility model matched moulds; This moment is because the elastic deformation of release link 3; Make fixed head 2 and push pedal 1 receive an active force that makes progress, lean spring, make spring be in impaction state.
When die sinking, cover half 10 separates with dynamic model 11, and the spring compression state release is given push pedal 1 and 2 one downward power of fixed head, makes to make foundry goods 8 stick on the dynamic model 11 by push rod 5 squeeze castings 8.
