Abstract
The utility model discloses a buckling position demolding auxiliary system. The buckling position demolding auxiliary system comprises a moving platen, an angle-lift block, a spring, a rotating plate, a baffle, and a rotating rod. The angle-lift block is slantingly connected with a side of the moving platen in sliding mode. A counterbore is arranged on the inner side of the top of the angle-lift block. The spring is sleeved in the counterbore. The middle of the rotating plate is connected with the upper portion of the angle-lift block in hinge mode. The outer side of the upper portion of the rotating plate is pressed against the outer end of the spring. The lower portion of the rotating plate is connected with the inner portion of the rotating rod in hinge mode through a rotating shaft. The outer end of the rotating rod comes out from the angle-lift block and extends into a mold cavity. The buckling position demolding auxiliary system is provided with the rotating plate, so that the rotating plate swings around a stationary shaft of the rotating plate under the action of spring force when a mold is opened and the rotating rod connected with the lower end of the rotating plate in hinge mode is driven to eject outward. The rotating rod can push the buckling position of a molded plastic product outward to break the buckling position away from a step face on the upper portion of the angle-lift block. Thus, smooth demolding of plastic products is achieved, the problems caused by product buckling position demolding such as product stress marks, product drag marks, products incapable of demolding and the like are effectively prevented, and demolding operation is reliable.
Description
Technical field
The utility model relates to a kind of injection mold, particularly relates to a kind of button bit demoulding accessory system.
Background technology
Development is plastics injection mould faster in the mould for plastics.Its plastic product is also being applied more and more widely in daily life, like each industrial circles such as building, machinery, electronics, instrument, instrument.When plastic shaping, not only require to improve the quality of products, enhance productivity, but also require mould structure simple, reduce producing wood.But to the working of plastics complex structure and have the product of button bit (protruding to the inside), the mould that has has a strong impact on the service life and the maintenance of injection mold in the mould emptier of deviating from product automatically more complicated also.
The utility model content
The purpose of the utility model is to provide a kind of button bit demoulding accessory system of simple in structure, demoulding reliable in action.
For realizing above-mentioned purpose, the technical solution of the utility model is:
The utility model is a kind of button bit demoulding accessory system, and it comprises moving platen, angled-lift splits, spring, flap, baffle plate, bull stick; The oblique side of slipping of described angled-lift splits at moving platen; Angled-lift splits inside top as a die cavity part is offered a counterbore, and described spring is nested with in this counterbore, and the flap middle part is hinged on the top of angled-lift splits through fixed axis; The upper outside roof pressure of flap is in the outer end of spring; The affixed baffle plate of the upper inner of flap, the bottom of flap is inner hinged through rotating shaft and bull stick, and the outer end of bull stick passes that angled-lift splits stretches into die cavity and over against the female parts of die cavity.
Described angled-lift splits has two, slips the both sides at moving platen respectively, and slip in gathering sill respectively the lower end of two angled-lift splitses.
The utility model also comprises the acceleration ejecting mechanism, and the push rod in this mechanism passes moving platen and stretches into die cavity.
After adopting such scheme; Because the utility model is provided with flap, during die sinking, this flap is swung around its fixed axis under the effect of spring force; And can drive with the hinged bull stick in its lower end and outwards eject; Bull stick can be located outside release with the button bit (protruding to the inside) of the plastic product of moulding, the cascaded surface that makes button bit break away from angled-lift splits top, thus realize the smooth demoulding of plastic product; When effectively having prevented the demoulding of product button bit caused product top white, draw white, can't the demoulding etc. problem, demoulding reliable in action.The parts of the utility model are less, and are simple in structure.
Below in conjunction with accompanying drawing and specific embodiment the utility model is further described.
Description of drawings
Fig. 1 is the structural representation of the utility model.
The specific embodiment
As shown in Figure 1, the utility model is a kind of button bit demoulding accessory system, and it comprises moving platen 1, angled-lift splits 2, spring 3, flap 4, baffle plate 5, bull stick 6, gathering sill 7 and quickens ejecting mechanism 8.
Described angled-lift splits 2 has two, oblique respectively slipping on the prism of moving platen 1 both sides, and slip respectively in gathering sill 7 lower end of two angled-lift splitses 2.Angled-lift splits 2 inside top as a die cavity part are offered a counterbore 21; Described spring 3 is nested with in this counterbore 21; Flap 4 middle parts are hinged on the top of angled-lift splits 2 through fixed axis 41, and the upper outside roof pressure of flap 4 is in the outer end of spring 3, the affixed baffle plate of the upper inner of flap 45 outsides; These baffle plate 5 medial roof lean against on the prism of moving platen 1, and moving platen 1 prism has limited the swing of flap 4 through baffle plate 5; The bottom of flap 4 is inner hinged through rotating shaft 42 and bull stick 6, and the outer end of bull stick 6 passes that angled-lift splits 2 stretches into die cavity and over against the female parts of die cavity, i.e. button bit 101 places of product 10.
In the present embodiment, be that example is described with two angled-lift splitses, each angled-lift splits 2 structure all is the same, repeats no more.
In order to satisfy the demoulding needs of finished product 10, the utility model also comprises acceleration ejecting mechanism 8, and the push rod 81 in this mechanism passes moving platen 1 and stretches into die cavity.
The operation principle of the utility model:
During die sinking; Angled-lift splits 2 moves up along moving platen 1 prism, breaks away from the restriction of moving platen 1 prism when moving to baffle plate 5, and flap 4 is outwards swung around fixed axis 41 under the effect of the spring force of spring 3; Drive with the hinged bull stick 6 in its lower end and outwards eject; Bull stick 6 can outwards be released button bit 101 places of the plastic product 10 of moulding, the cascaded surface 22 that makes button bit 101 break away from angled-lift splitses 2 tops, thus realize the smooth demoulding of plastic product.
The emphasis of the utility model just is: adopt flap to drive the mechanism that bull stick outwards ejects.
The above; Be merely the utility model preferred embodiment; The quantity of angled-lift splits can be had needs and decided; So can not limit the scope that the utility model is implemented with this, the equivalence of promptly doing according to the utility model claim and description changes and modifies, and all should still belong in the scope that the utility model patent contains.
