Abstract
The utility model discloses a high-angle pitched roof demoulding guide mechanism of a plastic mould. The mechanism comprises a mould bottom plate, wherein a support block is arranged on the bottom plate; a mold core is arranged on the support block; an upper top plate and a lower top plate are arranged in the support block; a combined sliding seat is arranged in the upper top plate and the lower top plate; an angle ejector rod is connected to the combined sliding seat and extends into the mold core; and the head part of the angle ejector rod is provided with an ejector cam insert. The high-angle pitched roof demoulding guide mechanism is characterized in that the bottom plate is internally provided with a lower guide rod fixing seat; a guide sleeve is arranged in the combined sliding seat; the bottom of the mold core is provided with an upper guide rod fixing seat; a guide rod penetrates through the guide sleeve; two ends of the guide rod are respectively connected with the upper guide rod fixing seat and the lower guide rod fixing seat; and the inclination of the guide rod is consistent with that of the angle ejector rod. Through adding the guide rod and the guide sleeve, the requirement of the large-button displacement demoulding of the plastic mould can be met, safety and reliability are achieved, and the service life of the plastic mould is ensured.
Description
Technical field
The utility model relates to the oblique top demoulding guiding mechanism of a kind of mould of plastics wide-angle, big stroke, belongs to the mould of plastics field.
Background technology
In mould of plastics, for the mould emptier of imperial palace button bit goods, cost is paid very high part often, generally is no more than 140MM with the oblique ejection stroke safe distance that pushes up of common oblique top mechanism; The angle maximum is no more than 14 degree; Through trigonometric function formula X (goods demoulding distance)=tan14 * 140-5 (safe distance), can get goods button bit maximum and must not surpass 30mm like this, replace otherwise get only the use cost height and make inner core pulling or inner slide mechanism complicated, that the cycle is long; For example oil cylinder or three template dies are that power drives big internal core-pulling mechanism and realizes; So not only cost of manufacture is high, risk is also very big, and the error of some annelet sometimes has very big influence to the normal demoulding of entire mechanism; Follow-uply just can only improve in process of production with constantly repairing a die; Modification repeatedly can be had a greatly reduced quality to the life-span and the Products Quality of mould, and particularly the reasonability of design organization is not grasped, and serious meeting causes whole pair of mould to scrap.
Summary of the invention
The purpose of the utility model is in order to overcome the shortcoming of prior art, to provide a kind of and can satisfy the big button bit demoulding of goods requirement through increasing guide rod, guide pin bushing, and is safe and reliable again, guarantees the large-angle inclined top demoulding of the mould of plastics guiding mechanism of die life.
The technical scheme of the large-angle inclined top demoulding of the utility model mould of plastics guiding mechanism is: comprise die bottom plate, the mould pin is installed on the base plate, on the mould pin core is installed; Upper plate and lower roof plate are set in the mould pin, are equipped with the combination slide in the upper and lower top board, connect angle ejector rod on the combination slide; Angle ejector rod stretches in the core, and the head of angle ejector rod is installed slanted kicking block, it is characterized in that installing in the described base plate lower guide rod holder; Mounting guide sleeve in the combination slide, the bottom of core is installed leader fixed, passes guide rod in the described guide pin bushing; Two of guide rod connects top guide bar holder and lower guide rod holder respectively, and the gradient of guide rod is consistent with the gradient of angle ejector rod.
The large-angle inclined top demoulding of the mould of plastics of the utility model guiding mechanism during work, drives combination slide and the angle ejector rod jack-up upwards together in the upper and lower top board by injection machine power; Owing in the combination slide, guide pin bushing has been installed, pass guide rod in the guide pin bushing, two of guide rod is connected on top guide bar holder and the lower guide rod holder; Like this when angle ejector rod makes progress jack-up; Guide rod and guide pin bushing just play the guiding role, and increase the intensity of angle ejector rod, make angle ejector rod can satisfy the big button bit demoulding of goods requirement; Safe and reliable again, guarantee die life.
Description of drawings
Fig. 1 is the structural representation of the large-angle inclined top demoulding of the utility model mould of plastics guiding mechanism.
The specific embodiment
The utility model relates to the large-angle inclined top demoulding of a kind of mould of plastics guiding mechanism, and is as shown in Figure 1, comprises die bottom plate 1; Mould pin 2 is installed on the base plate, core 3 is installed on the mould pin, upper plate 4 and lower roof plate 5 are set in the mould pin; Be equipped with combination slide 8 in the upper and lower top board, connect angle ejector rod 6 on the combination slide, angle ejector rod stretches in the core 3; The head of angle ejector rod 6 is installed slanted kicking block 7, it is characterized in that installing in the described base plate 1 lower guide rod holder 9, mounting guide sleeve 10 in the combination slide 8; The bottom of core 3 installs leader fixed 11; Pass guide rod 12 in the described guide pin bushing 10, two of guide rod 12 connects top guide bar holder 11 and lower guide rod holder 9 respectively, and the gradient of guide rod 12 is consistent with the gradient of angle ejector rod 6.During work, drive combination slide 8 and angle ejector rod 6 jack-up upwards together in the upper and lower top board 4,5 by injection machine power, owing in combination slide 8, guide pin bushing 10 has been installed; Pass guide rod 12 in the guide pin bushing 10; Two of guide rod 12 is connected on top guide bar holder 11 and the lower guide rod holder 9, and when angle ejector rod 6 made progress jack-up, guide rod 12 just play the guiding role with guide pin bushing 10 like this; Increase the intensity of angle ejector rod 6; Make angle ejector rod can satisfy the big button bit demoulding of goods requirement, safe and reliable again, guarantee die life.
