It is advanced optimized as to above-mentioned technical proposal:It is inlaid with wear-resisting edge on the curved pin surface and curved pin hole
Part.
The core-pulling mechanism of the present invention is by the inclined guide pillar of mold die sinking process with movable slider and angle ejector rod first to the muscle of plastic
Item and grab position carry out core pulling, then make sliding block, angle ejector rod, sliding block branch by the elbow collective effect of inclined guide pillar and curved pin again
Support seat and tilted footstock synchronize move to right so that oblique top leaves the bent hook part of plastic, facilitates the ejecting mechanism of injection molding machine by plastic top
Go out, i.e., realizes the core pulling of different angle by a secondary mold.
Description of the drawings
Fig. 1 is the assembly structure diagram of the present invention.
Fig. 2 is the structural schematic diagram of Fig. 1 inclined-tip core mechanisms.
Fig. 3 is the partial enlargement structural representation at the plastic core pulling position in Fig. 1.
Specific implementation mode
Present invention will be further explained below with reference to the attached drawings and specific embodiments.As shown in Figs. 1-3, refrigerator doorframe is noted
The curved pin secondary core-pulling mechanism of mould, including the slider support seat 5 that is slidably mounted on dynamic model and be fixed on cover half
Inclined guide pillar 2 is slidably fitted with sliding block 3 on the slider support seat 5, slanting guide pillar hole 33, the inclined guide pillar is formed on the sliding block 3
2 are inserted into the slanting guide pillar hole 33, and tilted footstock 6 is also installed on the slider support seat 5, is made on the tilted footstock 6
There is oblique top guide runner 61, the oblique top rod aperture at an angle with 5 upper surface of slider support seat is also formed on the sliding block 3
32, i.e. there is oblique top rod aperture 32 certain gradient, the gradient to be arranged according to core pulling angle.It is provided with oblique top in the oblique top rod aperture 32
One end of bar 4, the angle ejector rod 4 is formed with oblique top 42, and the other end of the angle ejector rod 4 is equipped with oblique top guide sliding base 42, described oblique
Top guide sliding base 42 is slidably mounted on the oblique top guide runner 61, and oblique top 42 therein makes 82 outer profile of grab and muscle of plastic
Item 81 is molded.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
82 inside molding of grab.Moving die insert 7, end system of the moving die insert 7 close to the oblique top 42 are installed on the dynamic model
There is insert core 71, insert core 71 is so that 83 inside of crotch of plastic is molded.Curved pin 1 is also installed on the cover half,
Elbow 11 is made in 1 end far from the cover half of the curved pin, and wherein elbow 11 is parallel with the inclined guide pillar 2.The sliding block branch
Support seat 5 is formed with curved pin hole 51, and the curved pin 1 runs through curved pin hole 51 and the dynamic model.
It is advanced optimized as to above-mentioned technical proposal:It is inlaid on 1 surface of curved pin and curved pin hole 51 wear-resisting
Mold insert.Maintenance cost is relatively low, and improves action stability, and extends die life.
Working principle of the present invention is as follows:When mold molds, active and inactive mold is opened, dynamic model drive slider support seat 5, sliding block 3,
Tilted footstock 6 moves down, as shown in Figure 1, simultaneously under the action of inclined guide pillar 2, sliding block 3 moves right relative to slider support seat 5
Dynamic, 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 gradient during being somebody's turn to do, tiltedly
Mandril 4 starts to move down to realize oblique top 42 to plastic under the oblique top rod aperture 32 and the collective effect of oblique top guide sliding base 41
Rib 81 carry out core pulling.Until slider support seat 5 reaches 11 position of elbow of curved pin 1, the rib to plastic is so far completed
81 and grab 82 core pulling, at this time oblique top 42 not yet touch crotch 83.
Then active and inactive mold continues to open, and dynamic model drives slider support seat 5, sliding block 3, tilted footstock 6 to continue to move down, sliding block
Support base 5 drives tilted footstock 6 and angle ejector rod 4 to start to move right in the case where the elbow 11 of curved pin 1 is acted on while moving down
It is dynamic so that oblique top 42 leaves the crotch 83 of plastic in horizontal position.During being somebody's turn to do, sliding block 3 also continues under the action of inclined guide pillar 2
Move right, due to elbow 11 with inclined guide pillar 2 be it is parallel, so sliding block 3 and slider support seat 5 synchronize move to right, this process
Sliding block 3, angle ejector rod 4, slider support seat 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 action.
The preferable specific, embodiment of the present invention 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.
