Abstract

The utility model discloses an die opening orderly, belonging to the technique field of die, which comprises an upper match-plate, a middle match-plate, and a lower match-plate, wherein a push rod is installed on the upper match-plate, the upper end of a resetting swing hook which is close to the push rod is installed on the middle match-plate, and the lower end is installed between a backing pin and the push rod on the lower match-plate. The utility model combines the push rod on the upper match-plate and the resetting swing hook the upper end of which is installed on the middle match-plate, and the lower end is installed between the backing pin and the push rod on the lower match-plate to ensure the die to open orderly, thereby the service life of the die is prolonged, the cost is reduced and the working reliability of the orderly opening of the die is improved.

Description

The mould of die sinking in order

Technical field

The utility model discloses a kind of mould of die sinking in order, belong to the technical field of mould.

Background technology

In the plastic mould production process, mould first die joint is opened, promptly alleged order die sinking prior to second die joint.For reaching this purpose, industry has been thought many ways, has designed many different servicing units, and what also have produces as standard component, uses.The servicing unit that uses mainly contains nylon and draws glue at present, spring, and five metals shutter and magnetic on/off device etc. are several.The shortcoming of these devices is: nylon draws glue, and spring easily lost efficacy, and the life-span is not long; Five metals shutter and magnetic on/off device then are that manufacturing cost is too high.

The utility model content

In order to overcome above-mentioned shortcoming, the utility model provides a kind of long-life, low cost and the mould of die sinking in order that has high reliability again.

To achieve these goals, the technical scheme that the utility model adopted is: a kind of mould of die sinking in order, comprise cope match-plate pattern, middle template, lower bolster, be installed with push rod on the described cope match-plate pattern, the swing hook upper end that resets that is close proximity to push rod is installed on the middle template, and the lower end places between the backing pin and push rod that is installed on the lower bolster.

Preferred as such scheme, described push rod and arranged on left and right sides is respectively equipped with the swing hook that resets, and the lower end of two swing hooks that reset links to each other by extension spring, also correspondingly on the lower bolster simultaneously is installed with two backing pins.In the push rod and arranged on left and right sides swing hook that resets is set respectively, but the balance push rod is stressed; The setting of extension spring can make the action of the swing hook disengaging backing pin that resets more reliable, and the swing hook of can further avoiding resetting simultaneously freely swings so that interfere with backing pin in the matched moulds process.

Offer groove on the described push rod, be installed with on the template in the while and draw pin, draw pin to place in the groove, both can slide relatively.Groove and the setting of drawing pin can use push rod simultaneously as controlled interval pull rod, further provide cost savings.

The described swing hook upper end that resets is fixedly arranged on the middle template by pivot pin and the swing hook that resets can rotate around pivot pin.

Described push rod, the swing hook that resets are made by metallic plate punching, can reduce cost.

Described pivot pin, backing pin selection standard screw can reduce cost.

The utility model in order die sinking mould in conjunction with the push rod on the cope match-plate pattern, be close proximity to push rod and an end be installed on the template, the other end places backing pin on the lower bolster and the swing hook that resets between the push rod, realize the orderly unlatching of mould, not only prolonged the service life of mould, reduce cost, and improved the functional reliability that mould is opened in order.

Description of drawings

Below in conjunction with the drawings and specific embodiments the utility model is described in further detail.

Fig. 1 is in the structural representation of matched moulds state for the utility model specific embodiment;

Fig. 2 is in the structural representation of the first somatotype state for Fig. 1;

Fig. 3 is the structural representation that Fig. 1 is in the first somatotype latter end;

Fig. 4 is that Fig. 1 is in first somatotype and finishes the structural representation of the state that second somatotype is just beginning;

Fig. 6 is the structural representation that Fig. 1 is in the state that first, second somatotype all finishes, i.e. die sinking finishes.

The specific embodiment

As shown in Figure 1, the utility model in order the mould of die sinking comprise cope match-plate pattern 5, middle template 6, lower bolster 7.Be installed with push rod 1 on the cope match-plate pattern 5, be close proximity to push rod 1 and arranged on left and right sides and respectively be provided with the swing hook 3 that resets, on the lower bolster 7, be positioned at that push rod 1 and arranged on left and right sides is also corresponding to be installed with a backing pin 4 respectively.Reset swing hook 3 upper ends be installed on the template 6, the lower end places between backing pin 4 and the push rod 1, promptly backing pin 4 is buckled in the swing hook 3 that resets.The lower end of two swing hooks 3 that reset also links to each other by extension spring 10.Also offer groove 12 on the push rod 1, be installed with on the template 6 in the while and draw pin 11, draw pin 11 to place in the groove 12, both can slide relatively.Reset swing hook 3 upper ends be fixedly arranged on by pivot pin 2 on the template 6 and the swing hook 3 that resets can rotate around pivot pin 2.Push rod 1, the swing hook 3 of resetting are made by metallic plate punching.Pivot pin 2, backing pin 4 selection standard screws.

The utility model working process of mould of die sinking in order is: shown in Fig. 2,3, when the mould die sinking, lower bolster 7 is motionless, up move by machine drive cope match-plate pattern 5 and push rod 1, the terminal chamfering transition position of the backing pin 4 because restriction of push rod 1, the swing hook 3 that resets can keep linking closely up to the place arrival push rod 1 that the swing hook 3 that resets contacts with push rod 1.During this period of time, because the swing hook 3 that resets in being installed on the template 6 fastens the backing pin 4 that is fixed on the lower bolster 7, template 6 is in closure state with lower bolster 7 in making, and opens the purpose of opening template so in order earlier than second die joint 9 all the time thereby reach first die joint 8.

As shown in Figure 4, after first somatotype finishes, the no longer restriction of drawn stem 1 of swing hook 3 that resets, then reset swing hook 3 under the effect of extension spring 10 to the centre swing, the swing hook 3 that resets breaks away from backing pins 4, no longer include between middle template 6 and the lower bolster 7 and pin down, under the drive of other die-sinking devices (scheme shown in this figure is that push rod 1 uses as pull bar, draws pin 11), shown in Fig. 5,6, middle template 6 is up moved, and finishes second somatotype.So far, die sinking finishes.
