Description

The master mold forced demoulding mechanism

[technical field]

The utility model relates to a kind of mold mechanism, is specifically related to a kind of master mold forced demoulding mechanism.

[background technology]

When producing plastic cement products, when the product outer ledge has the mechanism that needs forced stripper mechanism, product 100 as shown in Figure 1; The overhead kick 110 of its outer rim needs forced stripper mechanism; Traditional moulds needs two plate half module structures to produce, yet two plate half module structures are complicated, open mold twice; Part is more, thereby makes die cost higher.

In view of this, be necessary to provide a kind of novel master mold forced demoulding mechanism in fact, this master mold forced demoulding mechanism is simple in structure, only needs a die sinking, and can realize forced stripper mechanism with less part.

[summary of the invention]

Therefore, the purpose of the utility model provides a kind of master mold forced demoulding mechanism, and this master mold forced demoulding mechanism is simple in structure, only needs a die sinking, and can realize forced stripper mechanism with less part.

In order to achieve the above object, the master mold forced demoulding mechanism of the utility model, it is applied in the mould, and this mould comprises caster, male model plate, mother module core and male model benevolence, and this master mold forced demoulding mechanism comprises:

Guide pad, one of which end are fixed in the caster and mother module core of said mould;

Master mold is gone into son, and it is located in the said mother module core and also and between mother module core is provided with flexible member, and this master mold is gone into son above-mentioned guide pad slid in edge when the mould die sinking;

Block, one of which end are located at above-mentioned master mold and are gone in the son, and the other end stretches out this master mold and goes into son, and this block and this master mold go into to be provided with the stroke space between son;

Take off by force into son, its be located in the mother module core and and mother module core between be provided with flexible member, this takes off by force and is connected in above-mentioned master mold into son and goes into son and product overhead kick.

Especially, said guide pad is provided with the T type projection of inclination.

Especially, said master mold is gone into the T type groove that son is provided with inclination, and the T type groove of this inclination matches with the T type projection of above-mentioned inclination, thereby and above-mentioned T type projection be located at make in this T type groove master mold go into the son when the mould die sinking along the guide pad slid.

Especially, said flexible member is a spring.

Especially, to go into to be provided with in the son corresponding spatial accommodation located therein for block one end for said master mold.

Compared to prior art, the master mold forced demoulding mechanism of the utility model is simple in structure, only needs a die sinking, and can realize forced stripper mechanism with less part, has reduced die cost.

[specific embodiment]

See also shown in Figure 2, in present embodiment, the master mold forced demoulding mechanism of the utility model, it is applied in the mould, this mould comprises caster 200, mother module core 201, male model plate 300 and male model benevolence 301, this master mold forced demoulding mechanism comprises:

Guide pad 400, one of which end are fixed in the caster 200 and mother module core 210 of said mould, and this guide pad 400 is provided with the T type projection of inclination;

Master mold is gone into son 500; It is located in the

mother module core

201 and and 201 of mother module cores be provided with first flexible member 501; This first flexible member 501 is in compressed state when the mould matched moulds; This first flexible member 501 is a spring in present embodiment; This master mold is gone into the T type groove 502 that son 500 is provided with inclination, and the T type groove 502 of this inclination matches with the T type projection of above-mentioned inclination, thereby and above-mentioned T type projection be located at make in this T type groove 502 master mold go into sub 500 when the mould die sinking along guide pad 400 slid;

Block 600; The one of which end is located at above-mentioned master mold and is gone in the son 500; The other end stretches out this master mold and goes into son 500, and this master mold is gone into son, and to be provided with corresponding spatial accommodation in 500 located therein for block 600 1 ends, and this block 600 and this master mold are gone into sub 500 and be provided with the stroke space; Move behind the trip space so that this master mold is gone into son 500, this block 600 sticks master mold and goes into sub 500 and make its stop motion;

Take off by force into son 700; It is located in the

mother module core

201 and and 201 of mother module cores be provided with second flexible member 701; This second flexible member 701 is in compressed state when the mould matched moulds; This second flexible member 701 is a spring in present embodiment, and this takes off by force into son 700 and is connected in the overhead kick 110 that above-mentioned master mold is gone into son 500 and product 100.

See also Fig. 3 and shown in Figure 4; After the mould die sinking, male model plate 300 and caster 200 first die sinkings, male model plate 300 is to the direction motion away from caster 200; Because first flexible member 501 and second flexible member 701 stretch after the die sinking; Master mold go into son 500 under the elastic force effect of first flexible member 501 along guide pad 400 banking motions, promptly master mold is gone into both motions straight down of son 500, simultaneously level (away from product 100 overhead kicks 110 directions) motion left again; Going into son 500 when master mold is moving under the elastic force effect behind the stroke space of 600 of itself and blocks; Master mold is gone into son 500 stop motions under the barrier effect of block 600; This moment, master mold was gone into the overhead kick 110 that son 500 has broken away from product 100, let the overhead kick 110 of product 100 that certain deformation space 503 is arranged; When master mold is gone into sub 500 banking motions, take off son by force and 700 under the elastic force effect of second flexible member 701, move downward, take off son 700 motions then by force and accomplish stop motion behind its strokes.

See also shown in Figure 5ly, mould continues die sinking, makes product 100 accomplish forced stripper mechanisms.

When the mould matched moulds, take off by force into sub 700 breaking returns and get final product matched moulds.
