Show the various grotesque profiles of various concave curved surfaces, it is impossible to use side gate.Two is, in order to drop this section, to reduce the size of mould,
If with side gate it is necessary to reserve cast gate left and right sides channel size on mould, the increase cold burden hole on mould, jogger hole,
View picture die width, including the expense of some secondary process are increased, also includes wasting the runner in each mould product certainly
Gate materials.Three is that in order to attractive in appearance, the shearing of side gate occurs turns white and burr phenomenon.
But many unthinkable problems can be encountered in daily die trial, near the spot pouring mouth of product, it may appear that " climb
Stricture of vagina " is it sometimes appear that burr, needle-valve can make mould be difficult to repair spot pouring mouth outer ring jack-up during most serious.
Utility model content
This utility model provides a kind of spot pouring mouth and grinds guide-localization auxiliary device, there is provided the trickle reparation at cast gate,
Amendment cover half spot pouring mouth seals the surface roughness of charge level, and ensures that envelope material angle is consistent with thimble angle.
To solve above-mentioned technical problem, employ the following technical solutions：
Main body pipe fitting is respectively arranged at two ends with the first positioning sleeve and the second positioning sleeve, and grinding needle is sequentially inserted into described second determines
In position set, main body pipe fitting and the first positioning sleeve, grinding needle cutter head guide-localization to first positioning sleeve, the main body pipe fitting
Surface roughness requirements are 3.2 microns, and one end of first positioning sleeve is provided with groove, and a part of lapping liquid can be stored during grinding,
One end of the other end guide-localization of first positioning sleeve to the main body pipe fitting；The second positioning sleeve guide-localization is to institute
State the other end of main body pipe fitting；The Rockwell hardness number reached after first positioning sleeve and the second positioning sleeve heat treatment is
HRC48°-50°；Scalable centring ring is enclosed within outside the pipe shaft of the main body pipe fitting, the scalable centring ring bore area extra coarse
3.2 microns of degree, is 0.005mm-0.01mm with the fit clearance of the main body pipe fitting；The profile and cover half of first positioning sleeve
Hot-runner nozzle envelope charge level coordinates positioning, second positioning sleeve to position with model frame hot runner nozzle position location, and described first
The endoporus of positioning sleeve and second positioning sleeve and the diameter matches of the grinding needle, the endoporus of the main body pipe fitting is more than described
The endoporus of the endoporus of the first positioning sleeve and second positioning sleeve.
The beneficial effects of the utility model are：1st, quick positioning precision is high；2nd, various model cast gate amendments can be suitable for.

Specific embodiment
As shown in Figure 1：Main body pipe fitting 4 is respectively arranged at two ends with the first positioning sleeve 1 and the second positioning sleeve 3, the first positioning sleeve 1
One end be provided with groove, a part of lapping liquid can be stored during grinding, the other end guide-localization of the first positioning sleeve 1 is to main body pipe fitting 4
One end；The other end of the guide-localization of the second positioning sleeve 3 to main body pipe fitting 4；First positioning sleeve 1 and the heat treatment of the second positioning sleeve 3
The Rockwell hardness number for reaching afterwards is HRC48 ° -50 °；Scalable centring ring 2 is enclosed within outside the pipe shaft of main body pipe fitting 4, the first positioning sleeve 1
Coordinate with grinding needle with the endoporus of the second positioning sleeve 3, the endoporus of main body pipe fitting 4 is more than the endoporus of first positioning sleeve and described
The endoporus of the second positioning sleeve.
Fig. 2 show the schematic diagram of main body pipe fitting 4, and surface roughness requirements are 3.2 microns, that is, the part processing table for marking
Face has small peak valley unevenness, and the arithmetic average deviation of its rough surface profile crest to trough is 3.2 μm.
Fig. 3 show the schematic diagram of the first positioning sleeve 1, and there is one groove 7 in the first positioning sleeve left side, one can be stored during grinding
Divide lapping liquid, right side section guide-localization.Using the HRC standards processing in Rockwell hardness in heat treatment process, HRC is this part
Adopt 150KG load and drift angle and bore the hardness that injector is tried to achieve for 120 ° of diamond, be generally used for the very high material of hardness, such as quench
Firer's part, it is desirable to which the Rockwell hardness number reached after this part heat treatment is HRC48 ° -50 °.The endoporus of the first positioning sleeve 1 and grinding
