Specific embodiment
Present invention will be further explained below with reference to the attached drawings and specific embodiments.As shown in figures 1 to 6, injection mold The multi-direction core-pulling mechanism of sliding block, including sliding block 1, the sliding block 1 are slidably mounted on dynamic model, are formed with curved cotter way in the sliding block 1 101, the curved cotter way 101 is interior, and through curved pin 2 is equipped with, the curved pin 2 is fixed on cover half, is also formed with inclination in the sliding block 1 The oblique top slot 103 of setting, the oblique top slot 103 is interior through oblique top is equipped with, and the oblique top includes keeping product back-off 13 molding oblique The angle ejector rod 4 of top 12 and the connection oblique top head 12, as shown in Fig. 2, product back-off 13 is located in product a-quadrant.
In above-mentioned technical proposal: as shown in figure 4, the side of the sliding block 1 is equipped with auxiliary slider 8, the auxiliary slider 8 Side is formed with the fixture block 81 of protrusion, is formed with card slot on the corresponding position of the sliding block 1, on the fixture block 81 is located in the card slot Lower slider.
In above-mentioned technical proposal: the bottom of the auxiliary slider 8 is formed with I-shaped slot 82, and cooperation is equipped in the I-shaped slot 82 I-shaped guide rail 9, the I-shaped guide rail 9 are obliquely installed, and the I-shaped guide rail 9 is higher than far from one end of mould cavity close to mold The tilt angle of one end of die cavity, the I-shaped guide rail 9 is identical as core pulling angle needed for the demoulding of product B area, the present embodiment The tilt angle of middle I-shaped guide rail 9 is 15 ° (with 15 ° of horizontal direction angle).Groove is formed in the middle part of 9 two sides of I-shaped guide rail 91, the groove 91 is interior to be equipped with press strip 10, and the I-shaped guide rail 9 is fixed on the dynamic model by the press strip 10, the I-shaped Guide rail 9 is equipped with limited block 11 far from the bottom of mould cavity one end, and the limited block 11 is fixed on the dynamic model.The limit Block 11 plays certain supporting role to I-shaped guide rail 9, so that I-shaped guide rail 9 is obliquely installed.The inclination of I-shaped guide rail 9 is set It sets, is moved obliquely so that auxiliary slider 8 is driven by sliding block 1 along I-shaped guide rail 9, auxiliary slider 8 and the area product B are realized with this The core pulling in domain.
In above-mentioned technical proposal: as shown in figure 3, the tail portion of the angle ejector rod 4 is equipped with slider guide 7, the slider guide 7 is fixed On the dynamic model, the slider guide 7 includes sliding slot 71 and the slip plane 74 positioned at 71 two sides of sliding slot, the sliding The end of plane 74 is formed with limit plate 72, and the binding site of the slip plane 74 and the limit plate 72 is formed with arc groove 73, The arc groove 73 is communicated with the sliding slot 71.The tail portion of the angle ejector rod 4 is further fixed on shoes 6, as shown in fig. 6, the cunning Foot 6 includes the shoes main body being fixedly connected with the angle ejector rod 4 and the convex block 61 positioned at shoes main body two sides, described convex The bottom surface of block 61 is higher than the bottom surface of the shoes main body and forms shoes step 62 therewith, and the convex block 61 is located at the arc groove In 73, the shoes main body is in the sliding slot 71 between the limit plate 72, i.e., shoes 6 is limited by slider guide 7, so that sliding block It is unable to drive oblique top when 1 core pulling and does horizontal core pulling campaign, prevents product back-off 13 from being drawn by oblique top bad.
In above-mentioned technical proposal: being formed with the first limiting slot 41 and the second limit that section is arc-shaped on the angle ejector rod 4 Slot 42, the plane between first limiting slot 41 and second limiting slot 42 is lower than the upper surface of the angle ejector rod 4, described The limit steel of the planar movement between first limiting slot 41 and second limiting slot 42 is also equipped in oblique top slot 103 Pearl 5.42 pairs of limit steel balls 5 of first limiting slot 41 and the second limiting slot play the role of limit, when molding, limit steel ball 5 In first limiting slot 41;After injection molding, limit steel ball 5 is driven by sliding block 1 in the first limiting slot 41 and described the Planar movement between two limiting slots 42, since the upper surface of the angle ejector rod 4 is higher than the first limiting slot 41 and second limit Plane between the slot 42 of position, when limit steel ball 5 is moved in the second limiting slot 42, limit steel ball 5 is stuck.
In above-mentioned technical proposal: as shown in figure 5, the limit steel ball 5 includes cylinder 51, the cylinder 51 is fixed on described On the oblique top slot 103 of sliding block 1, it is formed with spring groove 52 in the cylinder 51, spring 53, the bullet are installed in the spring groove 52 One end of spring 53 is fixed on the slot bottom of the spring groove 52, and the other end is connected with ball 54.The limit steel ball 5 and the first limit The principle that slot 41, the second limiting slot 42 cooperate is: when sliding block 1 starts to be translated in core pulling, limit steel ball 5 is driven disengaging first Limiting slot 41, spring 53 is compressed at this time, and ball 54 is retracted in spring groove 52;When limit steel ball 5 moves to the second limiting slot 42 When, 53 elasticity release of spring, ball 54 is caught in the second limiting slot 42.
In above-mentioned technical proposal: the two sides of the sliding block 1 are equipped with press strip 3, and the lower part of the press strip 3 is recessed slide guide Step 31, the top of the 1 two sides side of sliding block are recessed the sliding block step 102 with the slide guide step 31 cooperation.It is described The cooperation of slide guide step 31 and the sliding block step 102 plays the role of slide guide to the core pulling process of sliding block 1, keeps its sliding more suitable Freely.
The course of work of the invention is as follows, and injection molding finishes, and active and inactive mold separation, curved pin 2 does translation core pulling with movable slider 1 backward Movement, sliding block 1 progressively disengage product, and auxiliary slider 8 is driven during being somebody's turn to do moves obliquely along I-shaped guide rail 9, with this reality The disengaging of existing auxiliary slider 8 and product B area.Since shoes 6 is limited by slider guide 7, while sliding block 1 translates core pulling, oblique top The core pulling straight up under the action of oblique top slot 103, the upward sliding in arc groove 73 of shoes 6 play the work of slide guide to oblique top With so that oblique top head 12 is detached from product back-off 13.At the same time, limit steel ball 5 is driven by sliding block 1 in the first limiting slot 41 and institute State and moved in the plane between the second limiting slot 42, due to the angle ejector rod 4 upper surface be higher than the first limiting slot 41 with it is described Plane between second limiting slot 42, when limit steel ball 5 is moved in the second limiting slot 42, limit steel ball 5 is stuck, next Oblique top is with 1 synchronous translational of sliding block.Convex block 61 has skidded off arc groove 73 at this time, i.e. shoes step 62 and slip plane 74 is located at same One plane, therefore during oblique top and 1 synchronous translational of sliding block, 71 translation along the chute of shoes 6 makes oblique top head 12 be detached from product A Region.
The preferred embodiment of the present invention has been described in detail above.It should be appreciated that those skilled in the art without It needs creative work according to the present invention can conceive and makes many modifications and variations.Therefore, all technologies in the art Personnel are available by logical analysis, reasoning, or a limited experiment on the basis of existing technology under this invention's idea Technical solution should all be fallen within the scope of protection of the present invention.
