The other end be fixed on the side of type core sliding block 15.
As shown in Fig. 4, Fig. 7 and Figure 20, for the structural schematic diagram before product 7 and latent cast gate 11 separation of casting, such as Figure 21
For the schematic diagram after separation.Product such as tail-gate outside plate.
It is as in figs. 17-19 the course of work of the present apparatus, Figure 17 is that core package is fastened in mold cavity component, for molding
State, Figure 18 are that 3 cylinder rod of oil cylinder is shunk, and the direction for pulling movable block 4 towards oil cylinder is mobile, since guide pad 14 is towards oil cylinder 3
One end is tilted to the left, therefore with movable slider 8 towards left slight movement, the mobile shovel base 6 of drive exists towards left slightly movement, type core sliding block 15
Towards moving left in slide opening 19, separate product 7 and latent cast gate 11.Figure 19 is that core package and mold cavity component separate, core package
Interior spring 16 withstands type core sliding block 15, collision when molding after preventing mobile shovel base 6 to be subjected to displacement in a free state.
After oil cylinder 3 is shunk, power is converted, the power of left and right directions is converted into power in the front-back direction, why is needed
The conversion of power is because if being directly connected to sliding block 8 with oil cylinder 3, and injection molding power is big, and 3 cylinder rod one of oil cylinder retreats, and it is extra to have
Material come out, injection molding power will pour greatly more, the power of sliding block 8 can be made bigger by the power of conversion, the power of injection molding can be withstood.
Mold is not drawn in figure, is not the protection content of this case.
The above is only the preferred embodiment of the utility model only, is not intended to limit the utility model, all at this
Within the spirit and principle of utility model, any modification, equivalent replacement, improvement and so on should be included in the utility model
Protection scope within.
