Abstract

The utility model is related to a kind of shell mould with anti-cracking function, including wax tree and the shell mould body being wrapped in outside wax tree, the wax tree includes wax-pattern and tree core, is connected between the wax-pattern and tree core by running channel, and the shell mould body is provided with sprue gate in tree core bottom;The wax-pattern is provided with wax-pattern projection, is wrapped in the shell mould body outside wax-pattern and forms the shell mould projection for being easy to cut on a corresponding position, the shell mould projection is provided with the dewaxing hole communicated with wax-pattern projection.The utility model existing shell mould be difficult on the position of de-waxing also can de-waxing completely, effectively prevent from causing shell mould spalling during de-waxing.

Description

A kind of shell mould with anti-cracking function
Technical field
The utility model is related to hardware product production field, more particularly to a kind of shell mould with anti-cracking function.
Background technology
In the lost wax casting technique of hardware, Making mold wax-pattern need to be first used, by drenching sand, being stained with slurry outside wax-pattern The shell mould of parcel wax-pattern is formed, recycles high steam to discharge the wax in shell mould.Current shell mould de-waxing process, be usually from The sprue gate dewaxing of shell mould.If product area is larger, complicated, running channel is caused to design unreasonable, shell mould is in de-waxing De-waxing will be produced not smooth, cause shell mould spalling, the product of cast out just occurs that the situation of string is scrapped or leaked in bulge.
Utility model content
In view of the shortcomings of the prior art, the purpose of this utility model is a kind of shell mould with anti-cracking function, and it is conducive to De-waxing, prevents from causing shell mould spalling during de-waxing.
To reach the purpose of this utility model, the technical scheme used for:
A kind of shell mould with anti-cracking function is provided, including wax tree and the shell mould body that is wrapped in outside wax tree, it is described Wax tree includes wax-pattern and tree core, is connected between the wax-pattern and tree core by running channel, and the shell mould body is provided with tree core bottom Sprue gate;The wax-pattern is provided with wax-pattern projection, is wrapped in the shell mould body outside wax-pattern and is formed on a corresponding position and is easy to The shell mould projection cut, the shell mould projection is provided with the dewaxing hole communicated with wax-pattern projection.
Preferably, a diameter of 3-5mm in the dewaxing hole.It is further preferred that a diameter of 4mm in the dewaxing hole.
Preferably, the dewaxing hole is the hole formed by drilling on shell mould.
Preferably, the dewaxing hole is that wax bar is connected on wax-pattern and is cut after shell mould body is finished formed by wax bar Hole.
The utility model can obtain following beneficial effect:
(1) the utility model is by setting dewaxing hole so that area is larger, baroque product shell mould is being unfavorable for From the position of running channel de-waxing also can de-waxing completely, effectively prevent shell mould spalling;
(2) the utility model is provided with the projection for being easy to cut, after the completion of de-waxing, and projection is cut, then cutting rear shape Into hole fill, the moulding by casting of hardware is not influenceed.
Brief description of the drawings
Fig. 1 is positive structure schematic of the present utility model;
Fig. 2 is the wax tree structural representation that wax bar is connected on the utility model wax-pattern used before shell mould is prepared;
Fig. 3 is the shell mode structure schematic diagram of prior art.
Embodiment:
The utility model is further described below with reference to the drawings and specific embodiments:
A kind of shell mould with anti-cracking function as shown in Figure 1, including wax tree 1 and the shell mould for being wrapped in the outside of wax tree 1 Body 2, the wax tree 1 includes wax-pattern 11 and tree core 12, is connected between the wax-pattern 11 and tree core 12 by running channel 13, the shell Mould body 2 is provided with sprue gate 21 in tree core 12 bottom;The wax-pattern 11 is provided with wax-pattern projection 14, is wrapped in the outside of wax-pattern 11 Shell mould body 2 forms the shell mould projection 22 for being easy to cut on a corresponding position, and the shell mould projection 22 is provided with convex with wax-pattern The dewaxing hole 23 that block 14 is communicated.A diameter of 4mm in the dewaxing hole 23.
In one embodiment of the present utility model, the dewaxing hole 23 is the hole formed by drilling on shell mould.
In another embodiment of the present utility model, the dewaxing hole 23 is that wax bar 15 is connected on wax-pattern 11 and is being done Hole formed by wax bar 15 is cut after complete shell mould body 2.The wax tree structure of wax bar is connected on wax-pattern used before shell mould is prepared As shown in Figure 2.
Shell mould of the present utility model is in dewaxing, and wax is mainly discharged from sprue gate 21, is difficult in shell mould on the position that dewaxes, Wax can be discharged from dewaxing hole, effectively prevent shell mould spalling;After the completion of de-waxing, projection can be cut, then after cutting The hole of formation is filled, and the moulding by casting of hardware is not influenceed.
As a comparison, the shell mould of prior art as shown in Figure 3, including wax tree 1 and the shell mould for being wrapped in the outside of wax tree 1 Body 2, the wax tree 1 includes wax-pattern 11 and tree core 12, is connected between the wax-pattern 11 and tree core 12 by running channel 13, the shell Mould body 2 is provided with sprue gate 21 in tree core 12 bottom.During dewaxing, wax can only be discharged from sprue gate 21, in baroque position On, wax is difficult to discharge, and is easily caused shell mould spalling.
Described above is only preferred embodiment of the present utility model, it is noted that for the general of the art For logical technical staff, on the premise of the utility model principle is not departed from, some improvements and modifications can also be made, these change Enter and retouch the scope also recorded without departing from the utility model.
