Abstract
The invention discloses a snap joint demoulding auxiliary system, which comprises a movable template, oblique sliding blocks, springs, rotating plates, baffles and rotating rods, wherein the oblique sliding blocks are obliquely connected with the side of the movable template in a sliding way, and the inner side of the top of each oblique sliding block is provided with a counterbore; each spring is sleeved in the counterbore, and the middle of each rotating plate is hinged with the upper part of each oblique sliding block; the outer side of the upper part of each rotating plate is pressed at the outer end of each spring, and the lower part of each rotating plate is hinged with the inner end of each rotating rod through a rotating shaft; and the outer end of each rotating rod penetrates through each oblique sliding block and extends into a mold cavity. Since the rotating plates are arranged in the auxiliary system, when a mold is opened, the rotating plate swings around a fixed shaft of the rotating plate under the action of spring force and can drive the rotating rod hinged with the lower end of the rotating plate to eject out; and the rotating rod can push a snap joint of a molded plastic product out, so that the snap joint is separated from a step surface of the upper part of the oblique sliding block, and thus the plastic product is smoothly demoulded, the problems that stress marks, drag marks, non-demoulding and the like caused during the snap joint demoulding of the product can be effectively solved, and the demoulding action is reliable.
Description
Technical field
The present invention relates to a kind of injection mold, particularly relate 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.
Summary of the invention
The object of the present invention is to provide a kind of button bit demoulding accessory system of simple in structure, demoulding reliable in action.
For realizing above-mentioned purpose, technical solution of the present invention is:
The present invention 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 present invention 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 present invention is provided with flap, during die sinking; This flap around the swing of its fixed axis, and can drive with the hinged bull stick in its lower end and outwards ejects under the effect of spring force, and bull stick can be located outside release with the button bit (protruding to the inside) of the plastic product of moulding; Make button bit break away from the cascaded surface on angled-lift splits top; Thereby 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.Parts of the present invention are less, and are simple in structure.
Below in conjunction with accompanying drawing and specific embodiment the present invention is further described.
Description of drawings
Fig. 1 is a structural representation of the present invention.
The specific embodiment
As shown in Figure 1, the present invention 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 present invention also comprises acceleration ejecting mechanism 8, and the push rod 81 in this mechanism passes moving platen 1 and stretches into die cavity.
Operation principle of the present invention:
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.
Emphasis of the present invention just is: adopt flap to drive the mechanism that bull stick outwards ejects.
The above; Be merely preferred embodiment of the present invention, the quantity of angled-lift splits can be had needs and decided, so can not limit the scope that the present invention implements with this; The equivalence of promptly doing according to claim of the present invention and description changes and modifies, and all should still belong in the scope that patent of the present invention contains.
