Abstract
The utility model discloses an investment casting mold which is characterized in that an integral water-dissolving urea core is divided into eight parting cores; eight S-shaped parting cores are reverse arranged; the eight S-shaped parting cores, a lower mold body and a core head of a central block are fixed together; eight bolts are fixed with the lower mold body; two square slide ways on the central block are tightly matched with the chute on the lower mold body, and finally matched together with the other assembled mold components. Therefore, the reverse installation avoids the problem of inaccurate positioning in the conventional assembly; during the mold opening process, the mold is reversely opened, a loose core and the bolts are respectively pulled up, and then an upper mold body is separated from a mold main body; due to the contraction of investment casting wax pattern, the wax pattern is tightly clasped with the central block, and the lower mold body is utilized for pulling up a formwork, so that the chute and the slide way can smoothly open the central block, a mold pulling-up mechanism is not required for being additionally designed.
Description
Technical field
The utility model relates to the investment casting mold of a kind of investment casting mold, particularly a kind of simplification.
Background technology
At present, for the foundry goods of die cavity more complicated, adopt of mould manufacturing loosed core methods such as ceramic core more in the model casting.Wherein whole water-soluble cored structure complexity, and whole water-soluble core is in use as easy as rolling off a log impaired, in addition, manufacture difficulty height, manufacturability are poor, assembly manipulation difficulty, manufacturing cost height.
Summary of the invention
In order to overcome the high problem of complex structure, operating difficulties, manufacturing cost that exists in the existing mould, it is a kind of under the prerequisite that guarantees casting dimension accuracy and quality that the utility model provides, the investment casting mold of simplification.
For achieving the above object, the utility model has been taked following technical scheme: investment casting mold comprises: upper die body, " S " shape divide core, loose core, latch, take out piece, lower mold body, middle pellet, slide groove, slideway.This mould is that the water-soluble urea core of integral body is divided into 8 branch cores; 8 " S " divides core oppositely to install; 8 " S " shapes divide the core print of core, lower mold body, middle pellet to be fixed together; 8 latches and lower mold body are fixed; Two square slideways on the central block and the slide groove on the lower mold body closely cooperate together, and last and other mold components that assemble fit together.The coarse problem in location in the conventional assembling has been avoided in reverse installation like this; In the die sinking process; adopt reverse die sinking; pull out respectively loose core, latch; subsequently upper die body and die main body are separated; because the contraction of model casting wax pattern makes that wax pattern and middle pellet obvolvent are tighter, utilizes lower mold body to do lifting plate; pellet during slide groove, slideway can be opened smoothly need not the otherwise designed pattern drawing mechanism.
The beneficial effects of the utility model adopt reverse assembling can accurately locate the branch core, make assembly be convenient to install; Utilize lower mold body to do lifting plate, making does not need the otherwise designed pattern drawing mechanism, has simplified investment casting mold, has more practicality under the prerequisite that guarantees dimensional accuracy, part quality.
Description of drawings
Fig. 1 is a general assembly drawing of the present utility model;
Fig. 2 is a fractionation structural representation of the present utility model.
Below in conjunction with drawings and Examples the utility model is further specified.
The specific embodiment
The utility model is to adopt patrix for the part that has " S " shape core, counterdie, and middle pellet, compositions such as alignment pin is characterized in that reverse installation mold, reverse die sinking utilizes slideway that patrix and middle pellet are taken up the branch mould.The water-soluble core of integral body is split as 8 branch core somatotype cores installations, and the method for reverse assembling can be accurate; alignment core is in the die sinking process; utilize lower mold body to do lifting plate, the design of slideway, slide groove makes that mold integral is simple in structure without the otherwise designed pattern drawing mechanism.
The utility model investment casting mold comprises: upper die body 1, " S " shape divide core 2, loose core 3, latch 4, take out piece 5, lower mold body 6, slide groove 7, middle pellet 8, slideway 9.
As shown in Figure 2, the utility model fusible pattern adopts oppositely assembling, and the water-soluble urea core of integral body is split as 8 branch cores, and is earlier that middle pellet 7 is fixing with lower mold body 6, divides 8 " S " shapes the core 2 and the core print of lower mold body 6, middle pellet 7 to be fixed together again; Divide core 7 fixing with counterdie 10 with 8 " S ", 8 latches 8 are fixing with counterdie 10, and two square slideways 9 on the middle pellet 8 closely cooperate together with the slide groove 7 on the lower mold body 6, and last and other mold components that assemble fit together.
In the die sinking process, adopt reverse die sinking, pull out respectively loose core 3, latch 4, subsequently upper die body 1 and die main body are separated, because the contraction of model casting wax pattern, make that wax pattern and 8 obvolvents of middle pellet are tighter, utilize lower mold body 6 to do lifting plate, pellet 8 during cooperation slide groove 7, slideway 9 can be opened smoothly.
