Abstract
The utility model relates to a double-side sliding core pulling mechanism of an injection mold, which comprises a fixed mold plate, an inclined guide pillar is arranged on the fixed mold plate, one end of the inclined guide pillar is provided with a slave slide block capable of sliding along the inclined guide pillar, a cylinder is also arranged on the fixed mold plate, the cylinder is arranged in an inclined way, the inclination degree of a piston rod is equal to the inclination degree of the inclined guide pillar, a main slide block is installed at the end part of the piston rod, cores for partially forming plastic products are arranged on both the main slide block and the slave slide block, and the main slide block and the slave slide block are linked through a telescopic mechanism. The core stripping of the traditional plastic product can be realized only through one to two cylinders. Compared with the traditional core stripping mechanism, the double-side sliding core pulling mechanism has simpler structure and lower mold manufacturing cost. Core stripping is carried out during the mold opening process, the entire production period of the product is shortened, and the production efficiency is increased.
Description
Technical field
The utility model relates to a kind of bilateral slip core puller of injection mold, belongs to the injection mold technical field.
Background technology
Plastic box as shown in Figure 5, that uses at present is quite extensive.According to actual needs, four of this plastic box sides generally all are shaped on pit 33.Therefore make in this plastic box process, before the demoulding, need the side direction fuse of these pits be extracted out earlier.The release method that adopts at present is four sides an oil cylinder (cylinder) to be installed all, and oil cylinder drives these fuses earlier and detaches plastic box before the demoulding.The complex structure of this injection mold, its cost are also quite high.And loose core earlier, the demoulding again causes the production cycle of product also longer.
The utility model content
The purpose of the utility model provides the bilateral slip core puller of a kind of simple in structure, low cost of manufacture, injection mold that production efficiency is high.
For reaching the technical scheme that above-mentioned utility model purpose the utility model adopted be:
The bilateral slip core puller of injection mold; Comprise solid plate, said solid plate is provided with Angle Pin, an end that it is characterized in that said Angle Pin be provided with can along this Angle Pin slide from slide block; Also be provided with oil cylinder on the said solid plate; Said oil cylinder tilts to place, and the gradient of its piston rod equates that with the gradient of said Angle Pin master slider is installed in the end of said piston rod; Said master slider and saidly from slide block, the fuse that makes plastic products locally-shaped is installed all, said master slider and said from slide block through the telescoping mechanism interlock.
In the technique scheme, said telescoping mechanism comprises that an end is fixed on the pole from the slide block, and said pole is provided with guide pin bushing outward, and said guide pin bushing is fixed on the said master slider.
The utility model only needs to compare with existing core-pulling mechanism having loosing core of plastic products now once realizing to two oil cylinders, and structure is simpler, and die manufacturing cost is lower.And in the process of die sinking, loose core, shortened the whole production cycle of product, improved production efficiency.
Further specify below in conjunction with the embodiment of accompanying drawing the utility model.

The specific embodiment
Shown in Fig. 1-4, a kind of bilateral slip core puller of injection mold comprises top board 2 and base plate 11, and said top board 2 is installed solid plate 7 through board 4, and cover half 15 is installed on the said solid plate 7, is shaped on die cavity on the said cover half 15.Moving platen 10 is installed on the said base plate 11, dynamic model 9 is installed on the said moving platen 10, be shaped on core on the said dynamic model 9, said core and said die cavity constitute die cavity.Said cover half 15 two ends are provided with Angle Pin 6, and Angle Pin 6 is installed on the solid plate 7.One end of said Angle Pin 6 be provided with can along this Angle Pin 6 slide from slide block 8; Also be provided with oil cylinder 18 on the said solid plate 7, said oil cylinder 18 tilts to place, and the gradient of its piston rod equates with the gradient of said Angle Pin 6; Master slider 19 is installed in the end of said piston rod; Said master slider 19 all is equipped with fuse with said from slide block 8, the effect of these fuses is to make 33 moulding of the pit of plastic products side, and said master slider 19 links through telescoping mechanism 27 from slide block 8 with said.Said telescoping mechanism 27 comprises that an end is fixed on the pole 26 from the slide block 8, and said pole is provided with guide pin bushing 25 outward, and said guide pin bushing 25 is fixed on the said master slider 19.
The course of work of present technique scheme is following:
Behind plastic product forming, injection machine drives dynamic model makes core separate with die cavity, in this process, oil cylinder drive master slider along the direction of piston rod outwards, to downslide, its downward component velocity equates with the dynamic model movement velocity.Master slider in motion process through telescoping mechanism outwards drive from slide block along Angle Pin, to downslide, the fuse on master and slave slide block breaks away from plastic products.By ejecting mechanism plastic products are ejected at last and accomplish whole demoulding action.
This core-pulling mechanism can be provided with one to two oil cylinder as required.When an oil cylinder is set, from slide block drive time from slide block (the opposite side slide block relative) with master slider outwards, to downslide.When two oil cylinders were set, the piston rod of another oil cylinder drove inferior to slide block (becoming master slider this moment) slip, and its stability is far above the stability that an oil cylinder only is set, so the present technique scheme adopts two oil cylinders to drive.
More than describe the preferred embodiment of the utility model in detail.The ordinary skill that should be appreciated that this area need not creative work and just can make many modifications and variation according to the design of the utility model.Therefore, all technical staff in the art, all should fall in the protection domain of the utility model on the basis of existing technology through the available technical scheme of logical analysis, reasoning, or a limited experiment according to the design of the utility model.
