The specific embodiment
(embodiment 1)
Fig. 1 to Fig. 6 has shown a kind of specific embodiment of folding modular system in the utility model.Wherein, Fig. 1 is a kind of left view of folding modular system in the present embodiment; A kind of full sectional view that dissects along the A-A line when Fig. 2 is in the matched moulds state for folding modular system among Fig. 1; A kind of full sectional view that dissects along the A-A line when Fig. 3 divides the mould state for the first time for folding modular system among Fig. 1 is in; A kind of full sectional view that dissects along the A-A line when Fig. 4 divides the mould state for the second time for folding modular system among Fig. 1 is in; A kind of cutaway view of Fig. 5 for dissecing along the B-B line among Fig. 4; Fig. 6 is a kind of perspective view of the positioning clamping pin of folding modular system in the utility model.
A kind of folding modular system of long service life, to shown in Figure 5, it comprises actuation arm 11, following actuation arm 31 and elastic reset spare 21 like Fig. 1; Said top of going up actuation arm 11 is fixedly connected with the side of moving platen 1 through pin 4, and the other end is to extending below; The bottom of said down actuation arm 31 is fixedly connected with the side of solid plate 3 through pin 4, and the other end extends upward; The inboard of said down actuation arm 31 is provided with and its guide chute that is provided with in the same way 32, saidly goes up that actuation arm 11 is arranged in the guide chute 32 of said actuation arm 31 down and along with the carrying out of folding mould action moves reciprocatingly at guide chute 32.
Said elastic reset spare 21 comprises elastic reset spare 23 and following elastic reset spare 24, said go up elastic reset spare 23 be positioned at said following elastic reset spare 24 directly over; Elastic reset spare 23 and following elastic reset spare 24 promptly are set no matter in matched moulds or die sinking process, can both produce enough reseting elasticities actuation arm 11 that makes progress and exert pressure through two elastic reset spares are set in the present embodiment; Prevent when carrying out corresponding actions; Last actuation arm 11 squints in guide chute 32, has also guaranteed the precision of entire die to a certain extent.Each said elastic reset spare 21 is arranged in the installing hole 22 of intermediate die plate 2 and is provided with over against said actuation arm down 31; Said actuation arm 31 down is provided with block 33; As shown in Figure 1; During matched moulds; The outboard end of said elastic reset spare 21 is against on the madial wall of actuation arm 11; The said top end face of going up elastic reset spare 23 is against down on the block 33 of actuation arm 31, thus this moment since the top end face of last elastic reset spare 23 be against down on the block on the actuation arm 31 with centre panel 2 with decide panel 3 relative fixed together, the outboard end of said elastic reset spare 21 of while is against on the madial wall of actuation arm 11 and has also guaranteed stablizing of intermediate die plate 2.
Each said elastic reset spare 21 comprises the positioning clamping pin 211 in said installing hole 22 and between installing hole 22 and positioning clamping pin 211, is used to the back-moving spring 212 that positioning clamping pin 211 provides reseting elasticity; The basic configuration of each said positioning clamping pin 211 is square, and its outer end is provided with first guiding surface 213, and is as shown in Figure 6; The said medial extremity of going up actuation arm 11 is provided with second guiding surface 13; The said medial extremity of actuation arm 31 down is provided with the 3rd guiding surface 34; Said block 33 is positioned at the top of said the 3rd guiding surface 34; During matched moulds, said second guiding surface 13 is between said block 33 and the 3rd guiding surface 34.
Said bottom of going up actuation arm 11 is provided with slide block 12, and the lower surface of said slide block 12 is a flat surface; Because frequent folding mould action; Will inevitably often rub between said upward actuation arm 11 lower ends and the elastic reset spare 21 is connected with slide block 12 through the bottom in last actuation arm 11, and this slide block 12 and said going up between the actuation arm 11 removably connect; In time its replacing is got final product in the time of normally to use in slide block 12 wearing and tearing; Need not change actuation arm 11, maintenance work is comparatively convenient, has good result of use.The width of said elastic reset spare 21 is greater than the said width of actuation arm 31 down, and is as shown in Figure 1.
The mould open/close modular system that scheme in the employing present embodiment is processed is when carrying out the action of folding mould; Through last actuation arm 11, closely cooperate between actuation arm 31 and the elastic reset spare 21 and accomplish the action of folding mould down; It is rational in infrastructure, the employing unique design; Having avoided traditional utilizes spring to carry out the folding mould to move issuable hidden danger, effectively guaranteed the quality of converted products, prolonged service life.
The course of work of this kind mould open/close modular system is roughly following:
During die sinking; At first moving platen 1 moves up and drives actuation arm 11 and moves up; Last actuation arm 11 is in the process that moves up; Said first inclined-plane 213 of going up elastic reset spare 23 streaks from said second guiding surface of going up on the actuation arm 11 13, and elastic reset spare 23 stressed being compressed get in intermediate die plate 2 installing holes 22 on this moment; And elastic reset spare 24 promptly resets owing to leaving away of last actuation arm 11 down; Its outer end is stretched out installing hole 22 and is against on the lower surface of actuation arm 11 (being the lower surface of slide block 12 in the present embodiment); Thereby prevent that moving platen 1 from moving downward to the matched moulds state, be in this moment and divide the mould state as shown in Figure 3 for the first time; Divide that to get into die sinking for the second time behind the mould be the die sinking of intermediate die plate the first time of accomplishing moving platen 1; As shown in Figure 4; Intermediate die plate 2 moves upward; And because the lower end of the last actuation arm 11 of moving platen 1 is against on the elastic reset spare 23, so said moving platen 1 keeps static relatively with intermediate die plate 2 and together moves upward, mold process was accomplished in whole minute.
Matched moulds is just in time opposite with the branch mold process; At first; Intermediate die plate 2 keeps static relatively with moving platen 1 and together moves downward, and when elastic reset spare 24 moved to down the 3rd guiding surface 34 of actuation arm 31 instantly, following elastic reset spare 24 was compressed in the installing hole 22 of intermediate die plate 2; Therefore last actuation arm 11 has also been broken away from the constraint of time elastic reset spare 24 and has been moved downward; Said first guiding surface 213 of going up elastic reset spare 23 streaks second guiding surface 13 of actuation arm 11, puts in place thereby make intermediate die plate 2 and moving platen 1 move in succession, accomplishes whole mould assembling action.
Obviously, the foregoing description of the utility model only be for explain clearly that the utility model does for example, and be not to be qualification to the embodiment of the utility model.For the those of ordinary skill in affiliated field, on the basis of above-mentioned explanation, can also make other multi-form variation or change.Here need not also can't give exhaustive to all embodiments.And conspicuous variation that these connotations that belong to the utility model are extended out or change still belong to the protection domain of the utility model.
