Abstract
The utility model provides an extrusion die casting die, which belongs to the field of extrusion casting and pressure casting machinery equipment. The extrusion die casting die arranged on a die casting machine comprises two parts, namely a fixed die and a movable die. The fixed die comprises a fixed die core and a fixed die plate. The fixed die core and the fixed die plate are connected together. An inclined pin and a wedging block are arranged on the fixed die plate. The movable die comprises a movable die core and a movable die plate. The movable die core and the movable die plate are connected together. A lateral slide block and an extrusion core are arranged on the movable die core. The movable die plate is connected with a support arranged at the outer side of the lateral slide block. An extrusion cylinder and an extrusion piston are arranged on the support. Aiming at the defective parts of die castings manufactured through the conventional die casting technology, the local extrusion feeding is additionally performed through the extrusion die casting die so as to realize the purposes of conventional die casting and filling, and extrusion die casting and feeding. Due to the adoption of a novel die casting machine equipped with the above extrusion die casting die, the highest specific pressure of the extrusion die casting and feeding is about 5 to 10 times that of the conventional die casting and press-shoot.
Description
Technical field
The utility model relates to a kind of die casting machine with the extruding die casting, belongs to extrusion casint, compression casting machinery apparatus field.
Background technology
Though the development of present domestic die casting industry is very fast, existing die casting machine can only satisfy common extrusion process production, and there are problems such as the not up to standard and mechanical strength of crackle, shrinkage and air-tightness is low relatively in the die casting that adopts common extrusion process to make.Push extrusion process on the other hand and can solve the existing quality problems of die-cast product that original simple extrusion process is produced.And existing common die casting machine is not provided with extruding die casting application function, can not satisfy the demand of extruding extrusion process.
Summary of the invention
In order to solve the problem of above-mentioned existence, the utility model provides a kind of functional structure that is applicable to the extruding die casting of installing on the common die casting machine that can satisfy extruding extrusion process demand.
The purpose of the utility model realizes through following technical proposals: the extruding die casting, and it is characterized in that: be made up of cover half, dynamic model two parts, cover half comprises cover half core, solid plate; The cover half core is connected with solid plate, and taper pin, wedge block are installed on solid plate, and dynamic model comprises moving-mould-core, moving platen; Moving-mould-core is connected with moving platen, and moving-mould-core is provided with side slide, extrusion die, and moving platen is connected with support; Support is positioned at the outside of side slide, and extrusion oil cylinder and extrusion piston are installed on support.
The beneficial effect of the utility model: the utility model adopts said structure, and through increasing the extruding die casting, the rejected region of the die casting that common extrusion process is made carries out part extruding feeding, realizes that common die casting fills type, pushes the purpose of die casting feeding.Adopt the die casting machine of the utility model extruding die casting, the highest extruding feeding specific pressure of extruding die casting is about 5-10 times of common die casting injection ratio pressure.This extruding die casting can be provided with extrusion oil cylinder in any open ended angle, space, guarantees that die casting obtains effective extrusion modling at the position that is prone to generation pore, shrinkage cavity.
Description of drawings
Fig. 1 is the structural representation that on common die casting machine, installs the extruding die casting additional.
Fig. 2 is the structural representation of extruding die casting among Fig. 1.
The specific embodiment
The extruding die casting is made up of cover half, dynamic model two parts, and cover half comprises cover half core 1, solid plate 11; Dynamic model comprises moving-mould-core 3, moving platen 12, and fixed half and moving half is installed in respectively on the quiet template 13 and movable plate 14 of common die casting machine, and cover half core 1 is connected with solid plate 11; Taper pin 5, wedge block 6 are installed on solid plate 11; Moving-mould-core 3 is connected with moving platen 12, and moving-mould-core 3 is provided with side slide 7, extrusion die 4, and moving platen 12 is connected with support 9; Support 9 is positioned at the outside of side slide 7, and extrusion oil cylinder 10 and extrusion piston 8 are installed on support 9.
The extrusion die 4 of extruding die casting, extrusion piston 8, extrusion oil cylinder 10 are as the local feeding mechanism of pushing; Reversal valve through die casting machine; The extrusion oil cylinder of control extruding die casting; Make extrusion piston 8 reaches, promptly when die casting machine carried out the injection supercharging, the extruding die casting was accomplished local extrusion modling.
The operation principle of extruding die casting: when die casting machine extruding die casting was in the matched moulds state, the taper pin 5 on the cover half slided to position shown in Figure 2 with the side slide on the dynamic model 7, and by wedge block 6 wedging side slides 7.At this moment between moving-mould-core 3 and the side slide 7, between taper pin 5 and the side slide 7, all leave 4-6 millimeters spacing between wedge block 6 and the side slide 7.When the Programmable Logic Controller (PLC) of die casting machine will push the compression signal notice extruding reversal valve of die casting; Extrusion oil cylinder 10 is in the die casting machine injection supercharging; Extrusion piston 8 reaches, extrusion die 4 carries out local extrusion modling to being in semi-solid foundry goods 2 in real time.The pressurize time-delay ends, the switching-over of extruding reversal valve, and machine die sinking after extrusion piston 8 backhauls, the side slide 7 on the dynamic model is thrown off wedge block 6, and taper pin 5 slips off side slide 7, pulls out extrusion die 4, the die sinking terminal point, the liftout tank of die casting machine ejects foundry goods 2.To ending, whole local extrusion process is accomplished.
