Detailed description of the invention
Referring to figs. 1 through Fig. 6, embodiment of the present utility model is described further.
As Fig. 1, Fig. 2, shown in Fig. 3 and Fig. 4, a kind of side core-pulling mould, comprise template 0 and die cavity 01, template 0 can be cope match-plate pattern 0 or lower bolster 0, bolster 0 is the difference of the setting position of side core-pulling mechanism, template 0 is provided with side core-pulling mechanism, side core-pulling mechanism comprises side slide 1 and controls the power part 2 of side slide 1 movement, power part 2 is cylinder or oil cylinder, cylinder is fixedly connected with side slide 1 with the piston rod of oil cylinder, side slide 1 is provided with the first thimble 12, first thimble 12 can be set directly on side slide 1, in order to process and convenient disassembly, on side slide 1, shoulder hole is offered in the utility model, the end of the first thimble 12 is arranged in shoulder hole, as shown in Figure 4, the quantity of the first thimble 12 is three, three described first thimbles 12 are around mold insert 41 distribution triangular in shape, therefore hole profiled sheeting 4 and ejector retainner plate 3 are provided with for wearing the first thimble 12, shoulder hole is coated with thimble fixed head 11, thimble fixed head 11 serves the effect fixing the first thimble 12, when facilitating Mould Machining, side slide 1 is holed and holes location, ejector retainner plate 3 and profiled sheeting 4 is slidably connected in side slide 1, lead 15 is provided with in side slide 1, ejector retainner plate 3 and profiled sheeting 4 are respectively arranged with the pilot hole 5 coordinated with lead 15, therefore ejector retainner plate 3 and profiled sheeting 4 can move in the guide direction of lead 15, the setting direction of lead 15 of the present utility model is identical with the moving direction of power part 2, profiled sheeting 4 is fixedly connected with side slide 1, therefore profiled sheeting 4 and side slide 1 are in company with movement, profiled sheeting 4 is provided with the mold insert 41 for forming part, ejector retainner plate 3 slippage on lead 15 connects, ejector retainner plate 3 is provided with the second thimble 31, second thimble 31 contacts with the surface of part, serve the effect of part when being supported on the demoulding, prevent part from moving along with mold insert 41 and sticking in forming surface, template 0 offers slippage slot, stroke block 14 is slidably connected in slippage slot, slippage slot 13 is offered in stroke block 14, profiled sheeting 4 is provided with the stroke block 14 coordinated with slippage slot 13, the both sides of stroke block 14 are provided with the bearing surface that can abut with the inwall of slippage slot.
The course of work of the present utility model is, cylinder controls side slide 1 and moves backward, then the first thimble 12 and mold insert 41 carry out the demoulding, second thimble 31 serves the effect of the thin-walled of support part, prevent when the first thimble 12 and second thimble 31 demoulding, mold insert 41 drags the problem that part carries out movement, forming surface is broken when preventing mold insert 41 from moving, then along with the continuation of the piston rod of cylinder is moved, profiled sheeting 4 can move backward, stroke block 14 now on profiled sheeting 4 can move along with the movement of profiled sheeting 4, until stroke block 14 abuts against with the bottom of slippage slot 13, then stroke block is made to move, until the bearing surface of stroke block 14 abuts with the sidewall of ejector retainner plate 3, thus stroke block 14 drags ejector retainner plate 3 moves backward, second thimble 31 leaves the arcwall face of injection-moulded plastic part, make the arcwall face demoulding of injection-moulded plastic part.
As shown in Figure 5, slippage slot 13 is at right angles trapezoidal, stroke block 14 is in trapezoidal, the bottom surface of stroke block 14 can abut with the right-angle surface of slippage slot 13, the inclined-plane of stroke block 14 can abut with the inclined-plane of slippage slot 13, prevent when stroke block 14 moves, huge tangential force is produced with stroke block 14, thus stroke block 14 is cut off, by inclined-plane is arranged on a surface of stroke block 14, can there is instantaneous abutting with the inclined-plane on slippage slot 13 in the inclined-plane on stroke block 14, thus fully contact, and prevents the contact position of the sidewall of slippage slot 13 and stroke block 14 from cutting off.
In the utility model, template 0 is provided with holder 3, slippage slot is arranged in holder 3, thus avoid be provided with slippage slot in core or die cavity 01, only need to have milled out slippage slot in holder 3, process convenient, decrease the difficulty of Mould Machining.As shown in Figure 2, in order to further fix the first thimble 12, in side slide 1, shoulder hole is provided with, the end of the first thimble 12 is arranged in shoulder hole, shoulder hole is coated with thimble fixed head 11, thus makes the shaping more accurate of the first thimble 12, and without the need to one-body molded.
As shown in Figure 5, groove 42 is provided with in forming surface, elastic component 43 is provided with in groove 42, one end of elastic component 43 abuts with stroke block 14, the other end of elastic component 43 plays the bottom abutting of groove 42, thus when the side of holder 3 abuts with stroke block 14, elastic component 43 can make stroke block 14 be compressed in groove 42, what then provide stroke block 14 and holder 3 side abuts power, strengthens the fixed effect between fixed block and profiled sheeting 4 further.
The above is only preferred embodiment of the present utility model, protection domain of the present utility model be not only confined to above-described embodiment, and all technical schemes belonged under the utility model thinking all belong to protection domain of the present utility model.It should be pointed out that for those skilled in the art, do not departing from the some improvements and modifications under the utility model principle prerequisite, these improvements and modifications also should be considered as protection domain of the present utility model.
