The product rib for stating the head and the oblique top surface of bullet needle contacts, and the tail portion for playing needle passes through the oblique top and is located at described
On the sliding slot of cushion block.
Advanced optimize as to above-mentioned technical proposal: the tail portion for playing needle is formed with ramp and lower inclined plane, described
Ramp is consistent with the ejection tilt angle of section, and the lower inclined plane is consistent with the tilt angle of reset section.
Advanced optimize as to above-mentioned technical proposal: the left end for playing pin hole, which is fixedly installed with, prevents the ejection
Block skids off the limited block of the macropore.
Compared with prior art, the utility model plays needle by being arranged in oblique top, when realizing ejection device on product
Rib and the mutual adhesion of oblique top so that product smoothly demoulds, clever structure is reliable, improves the qualification rate of product, more in fact
The property used.
Detailed description of the invention
Fig. 1 is the schematic diagram of the section structure before the utility model ejection.
Fig. 2 is the enlarged diagram in Fig. 1 at A.
Fig. 3 is the schematic diagram of the section structure of cushion block in the utility model.
Specific embodiment
The utility model is described in further detail with reference to the accompanying drawings and detailed description.As shown in Figure 1-3, injection mould
The oblique top Dan Zhen mechanism of tool, including cushion block 1 and oblique top 3, the cushion block 1 is fixed on oblique top slot, as shown in figure 3, the cushion block 1
On be formed with the sliding slot of V-shaped, the sliding slot includes ejection section 11 and reset section 12, and the both ends of the sliding slot are also formed with block face 13,
Non-shaded portion in Fig. 3 is the cell wall of sliding slot.Bullet pin hole is formed in the oblique top 3, the bullet pin hole is by macropore 31 and aperture
32 compositions, the macropore 31 are located at the left side of the aperture 32, and step 33, institute are formed between the macropore 31 and the aperture 32
It states to play to be equipped in pin hole and plays needle 2, ejection block 21 is formed on the bullet needle 2, is also arranged with spring 4, the top on the bullet needle 2
Block 21 and the spring 4 are respectively positioned in the macropore 31 out, and the both ends of the spring 4 are kept off with the step 33 and ejection respectively
Block 21 is in contact, and the head for playing needle 2 is contacted with the rib on 3 surface product of oblique top, and the tail portion for playing needle 2 passes through
The oblique top 3 is simultaneously located on the sliding slot of the cushion block 1.The bullet needle 2 is driven by oblique top 3 when moving, and plays the tail portion fitting of needle 2
Sliding slot translation on cushion block 1, block face 13 prevent the tail portion for playing needle 2 from skidding off cushion block 1.
In above-mentioned technical proposal: as shown in Fig. 2, the tail portion for playing needle 2 is formed with ramp 22 and lower inclined plane 23, it is described on
Inclined-plane 22 is consistent with the ejection tilt angle of section 11, and the lower inclined plane 23 is consistent with the tilt angle of reset section 12, that is, when ejecting
Ramp 22 fits with ejection section 11, and lower inclined plane 23 fits with reset section 12 when reset, so that the tail portion of bullet needle 2 is in cushion block
Movement on 1 is more smooth, does not shake, and stablizes to realize and play needle ejection device.In the entire ejection process of oblique top 3, needle 2 is played
It is resetted in retraction oblique top 3 again after completing ejection device movement therewith, playing needle 2 and increasing a reseting procedure is in order to avoid when oblique
Push up 3 core pulling strokes it is too long when, play the ejection part partial volume frangibility on needle 2, while being also prevented from and playing needle 2 long lasting for withstanding product
Make product holes.
In above-mentioned technical proposal: it is described play pin hole left end be fixedly installed with prevent the ejection block 21 skid off it is described greatly
The limited block 5 in hole 31.
In the present embodiment, since the surface of product rib is inclined-plane, oblique top 3 needs to be bonded rib surface and is obliquely installed, tiltedly
Bullet pin hole in top 3 also offsets from horizontal direction and is obliquely installed, the tilt angle of oblique top 3 be 12 ° (with 12 ° of vertical direction angle),
At the same time, cushion block 1 is also arranged with angle tilt, and the tilt angle of cushion block 1 is vertically arranged ejection section 11 just, correspondingly
The ramp 22 for playing 2 tail portion of needle is also vertically arranged, and guarantees that ramp 22 can be with ejection section during as oblique top 3 moves
11 fit, the rib on ejecting product.
The course of work of the utility model is as follows, injection mold die sinking after, oblique top 3 be injection molding machine drive do ejection fortune
It is dynamic, since oblique top 3 tilts 12 ° of settings, so the angle of the direction of motion of oblique top 3 and vertical direction is also 12 °, pacify at the same time
Bullet needle 2 in oblique top 3 is moved up also along 3 direction of motion of oblique top, and ramp 22 is moved along ejection section 11, due to ejecting section
11 are vertically arranged, and playing can move when needle 2 moves up under the active force of ejection section 11 in oblique top 3, while eject the extruding of block 21
Spring 4, the head for playing needle 2 are pierced by the surface of oblique top 3 gradually and slowly eject the rib of product.When moving to certain distance,
Rib on product has completely disengaged oblique top 3, and the tail portion for playing needle 2 at this time is just moved to reset section 12 and starts to reset, oblique top 3
Band needle 2 of moving continues to move up, while the elastic force of spring 4 also starts to discharge, and lower inclined plane 23 is moved along reset section 12, plays needle 2
Head slowly retracts in oblique top 3, limits until ejection block 21 is limited block 5, and lower inclined plane 23 is moved to the end of reset section 12,
The head for playing needle 2 is fully retracted in oblique top 3, is played the reset of needle 2 and is finished.The above are a complete ejection process, next entering
Before a injection cycle, position as shown in Figure 1 can be moved to again by playing needle 2.
The preferred embodiments of the present invention have been described in detail above.It should be appreciated that the ordinary skill people of this field
Member according to the present utility model can conceive without creative work makes many modifications and variations.Therefore, all this technology necks
Technical staff passes through logic analysis, reasoning or limited reality according to the design of the utility model on the basis of existing technology in domain
Available technical solution is tested, should all be fallen into the protection scope of the utility model.
