Part.
The inclined guide pillar band movable slider and angle ejector rod that the core-pulling mechanism of the utility model is opened process by mold are first to plastic
Rib and grab position carry out core pulling, sliding block, angle ejector rod, cunning are then made by the elbow collective effect of inclined guide pillar and curved pin again
Block support base and tilted footstock synchronize move to right so that oblique top leaves the bent hook part of plastic, facilitate the ejecting mechanism of injection molding machine that will mould
The core pulling of different angle is realized in part ejection by a secondary mold.
Detailed description of the invention
Fig. 1 is the assembly structure diagram of the utility model.
Fig. 2 is the structural schematic diagram of Fig. 1 inclined-tip core mechanism.
Fig. 3 is the partial enlargement structural representation at the plastic core pulling position in Fig. 1.
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, refrigerator doors
The curved pin secondary core-pulling mechanism of frame injection mold, including the sliding block support base 5 being slidably mounted on dynamic model and is fixed on cover half
On inclined guide pillar 2, be slidably fitted with sliding block 3 on the sliding block support base 5, be formed with slanting guide pillar hole 33 on the sliding block 3, it is described tiltedly
Guide post 2 is inserted into the slanting guide pillar hole 33, and tilted footstock 6, the tilted footstock 6 are also fixedly installed on the sliding block support base 5
On be formed with oblique top guide runner 61, the angle ejector rod at an angle with 5 upper surface of sliding block support base is also formed on the sliding block 3
Hole 32, i.e. oblique top rod aperture 32 have certain gradient, which is arranged according to core pulling angle.It is provided in the oblique top rod aperture 32 tiltedly
Mandril 4, one end of the angle ejector rod 4 are formed with oblique top 42, and the other end of the angle ejector rod 4 is equipped with oblique top guide sliding base 41, described
Oblique top guide sliding base 41 is slidably mounted on the oblique top guide runner 61, oblique top 42 therein make plastic 82 outer profile of grab and
Rib 81 forms.The sliding block 3 is formed with sliding block fuse 31 close to the end of the oblique top 42, and the sliding block fuse 31 makes plastic
Grab 82 inside form.Moving die insert 7 is installed, the moving die insert 7 is close to the end of the oblique top 42 on the dynamic model
It is formed with insert core 71, insert core 71 to form inside the crotch 83 of plastic.Curved pin is also fixedly installed on the cover half
1, elbow 11 is made far from the end of the cover half in the curved pin 1, and wherein elbow 11 is parallel with the inclined guide pillar 2.The sliding block
Support base 5 is formed with curved pin hole 51, and the curved pin 1 runs through curved pin hole 51 and the dynamic model.
It advanced optimizes: being inlaid on curved 1 surface of pin and curved pin hole 51 wear-resisting as to above-mentioned technical proposal
Mold insert.Maintenance cost is lower, and improves action stability, and extends die life.
The working principle of the utility model is as follows: when mold is opened, active and inactive mold is opened, and dynamic model band movable slider support base 5 is slided
Block 3, tilted footstock 6 move down, as shown in Figure 1, simultaneously under the action of inclined guide pillar 2, sliding block 3 relative to sliding block support base 5 to
It moves right, the sliding block fuse 31 on sliding block 3 starts the grab 82 for being detached from plastic.Since oblique top rod aperture 32 has tiltedly during being somebody's turn to do
Degree, angle ejector rod 4 start to move down to realize that oblique top 42 is right under the oblique top rod aperture 32 and the collective effect of oblique top guide sliding base 41
The rib 81 of plastic carries out core pulling.Until sliding block support base 5 reaches 11 position of elbow of curved pin 1, so far complete to plastic
The core pulling of rib 81 and grab 82, oblique top 42 not yet touches crotch 83 at this time.
Then active and inactive mold continues to open, and dynamic model band movable slider support base 5, sliding block 3, tilted footstock 6 continue to move down, sliding block
Support base 5 drives tilted footstock 6 and angle ejector rod 4 to start to the right in the case where the elbow 11 of curved pin 1 is acted on while moving down
It is mobile, so that oblique top 42 leaves the crotch 83 of plastic in horizontal position.Should during, sliding block 3 under the action of inclined guide pillar 2 also after
It is continuous to move right, due to elbow 11 with inclined guide pillar 2 be it is parallel, so sliding block 3 and sliding block support base 5 synchronize move to right, this mistake
Journey sliding block 3, angle ejector rod 4, sliding block support base 5 and tilted footstock 6 do not generate relative motion between any two.
Plastic is ejected vertically finally by the ejecting mechanism of injection molding machine, so that insert core 71 is detached from the crotch of plastic
83, it realizes the core pulling to 83 position of crotch, so far completes entire core_pulling demoulding movement.
The preferable specific, embodiment of the utility model is 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.
