Description
Technical field
The present invention relates to injection mold technologies, and in particular to a kind of handle concave arc core-pulling mechanism.
Background technology
Handle (knob) shown in similar Fig. 4 and Fig. 5 is widely used in every field due to highly practical.But at present
Handle by demoulding core pulling technology restriction, it is smooth excessive that the bottom 16 of indent can not be formed as the arc that Fig. 4 and Fig. 5 shows,
It is general more straight, seriously affect feel and usage comfort.
The content of the invention
The shortcomings that the purpose of the invention is to overcome prior art, provides one for the handle injection mold with arc concave shape
Kind can smooth core pulling and the successful handle concave arc core-pulling mechanism demoulded.
It is for realization goal of the invention the technical solution adopted by the present invention：
Handle concave arc core-pulling mechanism including arc-shaped core pulling block, pull rod, two hollow screw rods and is mounted on
Cooling water pipe on cover half, through hole is formed in the arc-shaped core pulling block, and two screw rods are respectively and fixedly installed to the arc and take out
The both ends of pellet through hole, the cooling water pipe run through the screw rod and the arc-shaped core pulling block through hole, the screw rod and institute
Stating arc-shaped core pulling block can rotate around the cooling water pipe, and one end of the arc-shaped core pulling block, which is made, makes the molding arc of handle indent
Hook, the lateral surface of the other end are formed with arc-shaped gear, rack are formed on the pull rod, and the arc-shaped gear is meshed with the rack, institute
The one end for stating pull rod is equipped with sliding block, and the sliding block is slidably arranged on the cover half, and the sliding block is driven by oil cylinder.
In above-mentioned technical proposal, the hot runner manifold above the cover half is further included, peace is fixed on the hot runner manifold
Equipped with closing piece, the closing piece is in handstand U-shaped, and the closing piece stretches into right in the cover half when injection mould closing is molded
The arc-shaped core pulling block is locked.
In above-mentioned technical proposal, graphite copper sheathing is installed between the screw rod and the cover half.
Compared with prior art, the handle that simultaneously can be smoothly demoulded using the injection mold injection molding of the present invention, indent
Bottom surface is the arcwall face unanimous on the whole with digital flexion direction, and comfort level is preferable.
Description of the drawings

Fig. 2 is the main parts sizes three-dimensional assembling structure schematic diagrames such as arc-shaped core pulling block in Fig. 1, pull rod；
Fig. 3 is sectional views of the Fig. 2 along pull rod centerline direction；
Fig. 4 is the handle dimensional structure diagram using the injection mold injection molding of the present invention；
Fig. 5 is the handle schematic cross-sectional view using the injection mold injection molding of the present invention.
Specific embodiment
With reference to the accompanying drawings and detailed description, the invention will be further described.As shown in Figs. 1-5, handle indent
Formula arc core-pulling mechanism, including arc-shaped core pulling block 1,2, two hollow screw rods 6 of pull rod and cold on cover half 13
But water pipe 7 are formed with through hole in the arc-shaped core pulling block 1, and two screw rods 6 are respectively and fixedly installed to the arc by pin 8
The both ends of 1 through hole of Loose core block.The cooling water pipe 7 runs through the screw rod 6 and 1 through hole of arc-shaped core pulling block so that spiral
Bar 6 and the arc-shaped core pulling block 1 can be rotated around the cooling water pipe 7.One end of the arc-shaped core pulling block 1, which is made, makes handle indent
Molding arc shaped hook 12, the lateral surface of the other end are formed with arc-shaped gear 11, rack 21, the arc-shaped gear 11 are formed on the pull rod 2
It is meshed with the rack 21, one end of the pull rod 2 is equipped with sliding block 4, and the sliding block 4 is slidably arranged in the cover half 13
On, the sliding block 4 is driven by oil cylinder 9.
Present invention additionally comprises the hot runner manifold 14 above the cover half 13, it is installed on the hot runner manifold 14
Closing piece 3, the closing piece 3, which is stretched into the cover half 13, when injection mould closing is molded carries out the arc-shaped core pulling block 1
Locking, since closing piece 3 therein is in handstand U-shaped, lock-out state pull rod 2 is placed exactly in the handstand U-shaped slot of closing piece 3.
The core pulling process of the present invention is as follows：Handle shaping postcooling water pipe 7 leads to cold water and arc-shaped core pulling block 1 is cooled down,
Risen again by injection molding machine driving hot runner manifold 14 and separated with cover half 13, until closing piece 3 releases the locking to arc-shaped core pulling block 1, most
Oil cylinder 9 is slided with movable slider 4 to 9 direction of oil cylinder afterwards, and during being somebody's turn to do, pull rod 2 drives arc-shaped core pulling block 1 to rotate, until arc is taken out
The arc shaped hook 12 of pellet 1 departs from the female parts of handle, completes core pulling.
In above-mentioned technical proposal, graphite copper sheathing 5, wherein graphite copper are installed between the screw rod 6 and the cover half 13
Set 5 is fixed on cover half 13, and screw rod 6 is rotatable compared with graphite copper sheathing 5, therefore graphite copper sheathing 5 is equivalent to bearing.It sets
The purpose of graphite copper sheathing 5 is to extend the service life of mold, and repairs and replaces more convenient, and cost is relatively low.
The preferred embodiment of the present invention described in detail above.It should be appreciated that those of ordinary skill in the art without
Creative work is needed according to the present invention can to 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.
