Fig. 2 is that a kind of synchronous different of the present invention is to the two core-pulling sliding block mechanism scheme of installation on mould of formula.
Detailed description of the invention
Fig. 1-2 is depicted as related description figure of the present invention; A kind of synchronous different is to the two core-pulling sliding block mechanism of formula, comprise compact heap pull bar screw 1, double trapezoid compact heap 2, outward take out slide body 3, outward take out slide body pull bar screw 4, limiting plate 5, outward take out slide body spring 6, in take out slide body pull bar screw 7, limiting plate screw 8, in take out slide body spring 9, in take out slide body 10, as shown in Figure 1.
Described core-pulling sliding block mechanism is loosed core inside and outside synchronously carrying out simultaneously; Described double trapezoid compact heap 2 is installed on mould template by compact heap pull bar screw 1; Limiting plate 5 is installed on mould template by limiting plate screw 8; Take out slide body about 10 in described and offer T-slot, lower T-slot and mould template slidable fit are installed, upper T-slot with take out slide body 3 outward and be slidably installed; Described double trapezoid compact heap 2 designs the design of two-layer trapezoidal faces; Take out in described in slide body 10 is provided with and take out slide body pull bar screw 7; Inside take out slide body spring 9 be placed in take out slide body pull bar screw 7, take out between slide body 10 and limiting plate 5 in installation site is in, for interior slide body 10 of taking out provides to inner core pulling power of loosing core; Described outer take out slide body 3 is provided with take out slide body pull bar screw 4 outward, take out cover on slide body pull bar screw 4 outward and take out slide body spring 6 outside having, taking out slide body spring 6 is outward installed on outside limiting plate 5, outwards loose core for taking out slide body 3 outward power of loosing core is provided, after mould is closed under static state, take out outward slide body spring 6, in take out slide body spring 9 and be in compressive state;
Further, illustrate for ease of operation principle of the present invention, the mould mating parts that Fig. 2 need point out comprises impression bolster 14, die cavity mold insert 13, core mold insert 12, core fixing plate 11; Corresponding, N is product wall thickness value, and L is outer outer Core-pulling distance distance values of taking out slide body 3, and M is product inwall blind hole depth value, and S takes out slide body 10 inner core pulling distance value in being; Double trapezoid compact heap 2 is installed on mould template impression bolster 14 by compact heap pull bar screw 1; Limiting plate 5 is installed on mould template core fixing plate 11 by limiting plate screw 8.
During real work, as shown in Figure 2, its motion operation principle is as follows:
Overall basic functional principle is: after mould die sinking, double trapezoid compact heap 2 respectively with take out slide body 3 outward and be separated with interior slide body 10 of taking out, take out outward under slide body 3 takes out the pulling of slide body spring 6 outside and outwards loose core, inside take out slide body 10 to take out to inner core pulling under the promotion of slide body spring 9 interior, thus reach same mechanism synchronous inside and outside the object of loosing core; Detailed process is:
1), when the synchronous complete mould of core-pulling die injection moulding is opened, under the pulling of injection machine push rod, mould dynamic model part moves down and is progressively separated with cover half part, now, and impression bolster 14, die cavity mold insert 13, compact heap pull bar screw 1, double trapezoid compact heap 2 stays in fixed die plate of injection molding machine side motionless, core mold insert 12, core fixing plate 11, take out slide body 3 outward, take out slide body pull bar screw 4 outward, limiting plate 5, take out slide body spring 6 outward, inside take out slide body pull bar screw 7, limiting plate screw 8, inside take out slide body spring 9, inside take out slide body 10 to follow dynamic model and retreat together, on double trapezoid compact heap 2 Yu outward, take out slide body 3, inside taking out slide body 10 presses the inclined-plane touched immediately to be separated, thus, take out slide body 3 outward and take out slide body spring 6 outside by under the pulling of taking out slide body pull bar screw 4 outward, the upper T-slot of slide body (10) is taken out by the slip pull-out of right shown in Fig. 2 in edge, take out slide body 3 to slide into limiting plate 5 position and blocked position until outer by it, complete outer the loosing core of L value distance, L=N+2 ~ 3mm, synchronously, inside take out slide body 10 interior take out the promotion of slide body spring 9 under, along in take out slide body (10) lower T-slot to slide passing by left shown in Fig. 2, until in take out slide body 10 and slide into the position that core fixing plate 11 limits, complete the inner core pulling of S value distance, S=M+2 ~ 3mm,
2) when resetting, under the promotion of injection moulding push rod, mould dynamic model part moves up and progressively to close with cover half part, now double trapezoid compact heap 2 respectively with take out slide body 3 outward and contact with the interior side trapezoidal inclined plane taken out on slide body 10, compressing is outer take out slide body 3 overcome outer take out slide body spring 6 resistance, in take out slide body 10 overcome in take out slide body spring 9 resistance return and reset, mould is completely closed, waits for the beginning of next injection cycle.
Specific embodiment described herein is only to the explanation for example of the present invention's spirit, those skilled in the art can make various amendment or supplement or adopt similar mode to substitute to described specific embodiment, but can't depart from spirit of the present invention or surmount the scope that appended claims defines.
