Description
Technical field
It the utility model is related to a kind of core preparation facilities, specifically a kind of portable moltening mold castings core for preparing
Preparation facilities.
Background technology
Model casting is also known as lost-wax casting, is a kind of common casting method, and model casting includes making wax-pattern pressure
The processes such as type, compacting wax-pattern, group weldering module, cleaning, shell making, dewaxing, Baking, smelting and pouring.This method can give birth to
The complex-shaped casting of output, and the casting dimension produced is accurate, surface roughness is small；Carbon steel, steel alloy, resistance to heat seal
The shaping of the alloy-steel castings such as gold, stainless steel, titanium alloy, copper alloy, aluminium alloy can use lost-wax casting.
Generally require directly to cast out tiny through hole or blind hole during casting, on investment-casting, the diameter of through hole or blind hole is 2
In the range of ~ 8mm, the through hole of formation small diameter or blind hole generally have two methods on investment-casting, and one kind is on wax-pattern
Direct coating stucco is formed, and another kind is special to make ceramic core and be installed on wax-pattern at respective through hole or blind hole.Due to
The inwall of elongated hole and blind hole is not easy to coat and stucco on investment-casting during shell processed, and therefore, second method becomes existing
The common method of investment-casting is produced in technology.
In the prior art, the preparation method of moltening mold castings ceramic core is mainly the most extensive with hot drape process, hot pressing note
The production process of method is：Using matrix material and mineralizer as dispersed phase, organic plasticizers are medium, make powder after heated mixing
Slurry is formed with plasticizer, by slurry injection-compression molding, required ceramic core is formed after repairing, be calcined, strengthen.It is but hot
Pressure injection ceramic core needs special mold and advanced hot pressing note equipment, invests larger, complex procedures, and operation is difficult, the cycle
Slowly, the cost of small lot production is larger for longer, reaction, is unsuitable for small lot production；Therefore, it is low suitable for small quantities of to need a kind of cost badly
Measure the core preparation facilities of production.
The content of the invention
The purpose of this utility model is to provide a kind of cost the low core preparation facilities suitable for small lot production.
To achieve the above object, the technical solution of the utility model is：
A kind of portable core preparation facilities, including sleeve pipe and the push rod for being oriented in threading, inside pipe casing structure
Into the forming cavity for filling core material, sleeve pipe is externally provided with handle, the push rod to the inwall having less than front end with sleeve pipe
The outer peripheral face of cooperation is slidingly sealed, the front end face of push rod is for being compacted core material and releasing the preceding pressure surface of core material.
The handle is butterfly handle, butterfly handle include two Handheld Divisions in left and right and between two Handheld Divisions with set
The connecting portion of pipe connection.
The connecting portion of handle offers threaded perforations, and sleeve outer wall is provided with external screw thread, and the handle is removable by screw thread
It is connected on sleeve pipe.
Each Handheld Division includes the transition that becomes larger of transverse width and the constant constant-breadth section of transverse width, transition
The larger one end of width is gradually reduced after elder generation gradually increases from left to right towards connecting portion, the transverse width of connecting portion.
One end of the remote transition of constant-breadth section is circular arc.
One end of the push rod is provided with the gear edge being used for the spacing cooperation in end face of sleeve pipe.
The beneficial effects of the utility model are：Core preparation facilities of the present utility model is portable, including sleeve pipe and pushes away
Bar, inside pipe casing form the forming cavity for filling core material, and the outside of sleeve is provided with handle.The front end face of push rod be for
Compacting core material simultaneously releases the preceding pressure surface of core material, and push rod extremely has less than front end to be used to be slidingly sealed with the inwall of sleeve pipe
The outer peripheral face of cooperation.After core material is filled in sleeve pipe, push rod is oriented to and is installed in sleeve pipe, the preceding pressure surface extrusion pressing type of push rod
Core material consolidates core material, and when push rod is oriented to slip in sleeve pipe, there is push rod the inwall with sleeve pipe to be slidingly sealed cooperation
Outer peripheral face, prevent core material from being extruded between internal surface of sleeve pipe and push rod.It is manual using push rod after core material is filled
Core material after shaping is released outside sleeve pipe from sleeve pipe.Core preparation facilities cost in the utility model is low and is easy to take
Band, core is prepared using manual operation, substantially reduces manufacturing cost, produced suitable for small lot.
