Background technology
In existing injection forming mold structure, the general independently core-pulling mechanism that adopts separately of back-off in the goods on the different directions, and for internal core-pulling mechanism, when there are three limit back-offs the inboard of plastic products, when particularly there is back-off the both sides of the oblique top direction of motion, adopt above-mentioned independent separately core-pulling mechanism, when oblique top is moved, then can reciprocal influence, thus can't loose core.
The utility model content
The purpose of this utility model be for provide a kind of in the injection mold goods side back-off position of view picture is arranged, have simultaneously in the direction of motion both sides of taking off back-off the glue position or even when also having one or both sides face back-off, can realize the core-pulling mechanism of the little oblique top of big oblique top band of loosing core smoothly.
For achieving the above object, the little oblique top core-pulling mechanism of a kind of big oblique top band comprises big oblique top, big angle ejector rod, big oblique top pipe position piece, oblique top slide block and ejector retainner plate; Big oblique top pipe position piece is located in the mould, and has the guide runner for big angle ejector rod motion; The upper end of big angle ejector rod is connected with big oblique top, and the lower end passes guide runner and the oblique top slide block is fixed, and the oblique top slide block is connected with ejector retainner plate by T type structure; Be provided with second guide mechanism between described big oblique top and the mould; Described big oblique top both sides are provided with little oblique top; Big oblique top and and little oblique top between be provided with first guide mechanism that can make little oblique top horizontal movement; Little oblique top lower end is provided with little angle ejector rod; The middle part of little angle ejector rod is provided with little oblique top pipe position piece, and little oblique top pipe position piece is provided with the guide runner of supply and marketing angle ejector rod motion, and little oblique top pipe position piece is installed in the mould.
Said structure, owing to be provided with big oblique top, big angle ejector rod, big oblique top pipe position piece, oblique top slide block and ejector retainner plate, between big oblique top and mould, be provided with second guide mechanism, when ejector retainner plate moves, big oblique top moves upward, simultaneously, big oblique top is also to the internal motion of plastic products, thereby reaches the purpose of throwing off plastic products one side back-off; Owing to be provided with little oblique top in big oblique top both sides, be provided with first guide mechanism between big oblique top and the little oblique top, when big oblique top was moved, little oblique top was also followed big oblique top and is moved upward, simultaneously, under the effect of first guide mechanism, little oblique top moves horizontally on big oblique top direction, thereby arrives the purpose of throwing off the other both sides of plastic products back-off, therefore, adopt said structure, can simultaneously the back-off on plastic products three limits be thrown off simultaneously.
Specialize as of the present utility model, described first guide mechanism is the T shape bar and the sliding tray that is located on the little oblique top that is located on the big oblique top.This simple in structure, easy to process.
Specialize as of the present utility model, described second guide mechanism is second guide runner and the 2nd T shape bar that is located on the mould that is located on the big oblique top.This simple in structure, easy to process.

The specific embodiment
Below in conjunction with the drawings and specific embodiments the utility model is further elaborated as Fig. 1 to the little oblique top core-pulling mechanism of big oblique top band shown in Figure 6, comprises big oblique top 1, little oblique top 2, big angle ejector rod 3, little angle ejector rod 4, big oblique top pipe position piece 5, little oblique top pipe position piece 6 and ejector retainner plate (not shown), oblique top slide block 15; Big angle ejector rod 3 is fixing with oblique top slide block 15, and oblique top slide block 15 links to each other with ejector retainner plate by T type structure; Big oblique top pipe position piece 5 and little oblique top pipe position piece 6 are installed in the mould, have the guide runner for big angle ejector rod 3 motions on big oblique top pipe position piece 5, have the guide runner for little angle ejector rod 4 motions on little oblique top pipe position piece 6; As shown in Figure 6, big oblique top 1 and big angle ejector rod 3 are installed together; As shown in Figure 5, little oblique top 2 and little angle ejector rod 4 are installed together; As shown in figures 1 and 3, be located at the both sides of big oblique top 1 in little oblique top 2, between little oblique top 2 and big oblique top 1, be provided with first guide mechanism that makes little oblique top horizontal movement, as shown in Figure 3 and Figure 4, described first guide mechanism comprises T shape bar 7, the sliding tray 8 of processing on little oblique top 2, described T shape bar 7 is installed on the big oblique top 1 by press strip 12, and under the effect of sliding tray 8 and T shape bar 7, little oblique top 2 can move horizontally on big oblique top 1; As Fig. 3, on big oblique top 1, also be provided with second guide mechanism, comprise the 2nd T shape bar 9 and second sliding tray 10, the 2nd T shape bar 9 is installed on the mould, and second sliding tray 10 is provided with second press strip 11, like this, when second press strip 9 is moved, do not break away from second sliding tray 10 in second sliding tray 10.
The core-pulling mechanism of said structure, in the time of after plastic product forming is intact, need ejecting, ejector retainner plate promotes big angle ejector rod by the oblique top slide block and little angle ejector rod moves upward, and in motion process, big angle ejector rod promotes big oblique top motion, little angle ejector rod promotes little oblique top fortune merit, big oblique top not only moves upward when motion, under the guide effect of the big angle ejector rod and second guide mechanism, also to horizontal motion, to reach the purpose of throwing off the inboard back-off of plastic products; Little oblique top is when motion, because the motion gradient of big angle ejector rod is greater than the motion gradient of little angle ejector rod, the horizontal motion stroke of little oblique top is less than the horizontal motion stroke of big oblique top when ejecting, simultaneously owing to be provided with first guide mechanism, therefore, little oblique top not only moves upward under the guide effect of little angle ejector rod, under the effect of T shape bar and sliding tray, little oblique top moves horizontally to big oblique top direction, like this, the back-off that just can throw off the plastic products inboard on other both directions except that big oblique top.Therefore, adopt the core-pulling mechanism of said structure, can realize throwing off simultaneously the purpose of plastic products three limit back-offs smoothly, and simple in structure, easy to process.
