Description

A kind of trestle component investment casting mold

Technical field

It the utility model is related to a kind of trestle component investment casting mold.It is to be related to irregularly logical hole type parts model casting Field question.

Background technology

The framework that trestle component is played a supporting role in the electrical apparatus, larger power can be born, there is positioning action, Make to keep correct positional precision between part.Support small in volume, durability are high, will not waste unnecessary body during installation Product space, carry out mo(u)lded piece blank using hot investment casting, hot investment casting is different from conventional pressure casting or sand casting, precision casting Relatively accurate contoured and higher casting accuracy can be obtained by making.The relatively conventional compression casting of size of casting is much smaller, expands The size range of casting is opened up.Hot investment casting does casting mold raw material with wax, and modification is flexible, and can recycle, can be big It is big to save production cost.More widespread practice is：The mould of wax-pattern needed for making first, then wax is cast with the method for casting, obtain Obtain original wax-pattern.Resistant to elevated temperatures liquid sand material is painted in wax-pattern last layer layer.Treat to dry after enough thickness, then heat, The wax-pattern of inside is melted away, obtains the die cavity consistent with required blank.Then, will be outer after solidification to molten iron of casting in die cavity Shell removes, and just can obtain high-precision finished product.

In view of the economy and precision of the processing of trestle component investment casting mold volume block, original uses cylindrical type Core, it is actual according to factory so selection automatic wax injector making wax-pattern because part is high-volume and quality is again smaller, The casting mouth of the wax injector is in the side of mould.

The content of the invention

The purpose of this utility model is exactly to solve the above problems, there is provided a kind of trestle component investment casting mold, it With the advantages of simple in construction, easy to operate.

To achieve these goals, the utility model adopts the following technical scheme that：A kind of trestle component investment casting mold, It is characterized in that it includes moving platen and two cores, described two cores are arranged on moving platen, and two cores lead to moving platen Cooperation is crossed to fix, moving platen is connected by soket head cap screw with Bottom clamp plate, two cores on moving platen, with cushion block and Top clamping plate is connected by hexagon socket cap head screw, and during matched moulds, moving platen synthesizes near closed hollow ring with core and solid plate.

Trestle component investment casting mold is upper lower open die, and two cores are installed on Bottom clamp plate, for convenience of institute is molded So that the core is fixed together with moving platen by coordinating.Two push rods, ejecting mechanism are provided with the bottom of solid plate Coordinate the push rod of automatic casting motor spindle, wax part automatic ejection can be achieved.

The utility model has the advantages that：

The utility model is simple in construction, easy to operate, solves the problems, such as the model casting difficulty of support parts, and carry High operating efficiency.

Embodiment：

The utility model is described in further detail with embodiment below in conjunction with the accompanying drawings：

As shown in Figures 1 to 7, a kind of trestle component investment casting mold, it is characterized in that, it includes solid plate 4, core one 1 and core 2 19, the core 1, core 2 19 are arranged on moving platen 3, and core 1, core 2 19 pass through interference respectively Cooperation is fixed with moving platen 3, and moving platen 3 is connected by eyelet bolt 2 and wing nut 18 with solid plate 4, and the solid plate 4 is Solid die, it is connected with cushion block 6 and top clamping plate 8 by soket head cap screw 11.

During matched moulds, because mould is acted on by downward thrust, move downward moving platen 3, in order to ensure to Alignment pin is mounted with the accuracy of the lower direction of motion, moving platen 3 and solid plate 4, moving platen 3 and solid plate 4 synthesize enclosed type Chamber, complete matched moulds process and start to penetrate wax；Penetrate after the completion of wax, the core 1 of mould rises, and departs from wax part, then push rod is fixed Plate 7 and push pedal 9 are moved upwards, in order to ensure the accuracy of the upward direction of motion, in ejector pin retaining plate 7 and push pedal 9 and solid plate 4 Push pedal guide pillar 15 is mounted directly, hexagon socket cap head screw is connected by coordinating with top clamping plate 8, in the He of ejector pin retaining plate 7 In 9 upward motion process of push pedal, push rod 12 releases wax part, and after wax part takes out completely, ejector pin retaining plate 7 and push pedal 9 move to Initial position, complete the process for taking out wax part.
