Detailed Description

The technical scheme of the utility model is further explained in the following with the attached drawings. The following examples are only for illustrating the technical solutions of the present invention more clearly, and the protection scope of the present invention is not limited thereby.

As shown in fig. 1, the utility model discloses a mould of many sliders, including oblique guide pillar 6, still include interior slider core 4 and cover and establish the outer slider core 5 in interior slider core 4 periphery, interior slider core 4 is connected with interior slider core fixing base 2, outer slider core 5 is connected with outer slider core fixing base 3, be provided with first through-hole 21 on the interior slider core fixing base 2, first through-hole 21 is the same with the diameter of oblique guide pillar 6, be provided with second through-hole 31 on the outer slider core fixing base 3, the diameter of second through-hole 31 is greater than the diameter of oblique guide pillar 6, first through-hole 21 and second through-hole 31 are passed to oblique guide pillar 6.

When the die is used, because no gap exists between the inner slide block core fixing seat 2 and the inclined guide post, the die opening can pull the inner slide block core fixing seat 2 instantly, after the stroke is several millimeters, the gap distance between the outer slide block core fixing seat 3 and the inclined guide post 6 does not exist, the inclined guide post 6 can pull the outer slide block core fixing seat 3, finally, the inclined guide post 6 is also separated from the slide block, the die is opened, and the product is ejected under the action of the push plate 10 and the delay pin 11.

Furthermore, a first limiting block 8 is arranged on the outer slider core fixing seat 3, and a first limiting clamping groove 22 corresponding to the first limiting block 8 is arranged on the inner slider core fixing seat 2. The inner slide block core fixing seat 2 stops moving along with the inclined guide post 6 through the first limiting block 8, the first limiting block 8 is a limiting stopper, a spring is arranged below the limiting stopper, and the limiting stopper touches the first limiting clamping groove 22 to play a limiting role.

Furthermore, a first limit screw 12 is arranged on the outer slide block core fixing seat 3. The first limit screw 12 prevents the inner slide core fixing seat 2 from flying out.

Furthermore, a second limit block 9 is arranged on the mold 1, and a second limit clamping groove 32 corresponding to the second limit block 9 is arranged on the outer slide block core fixing seat 3. The outer slide block core fixing seat 3 stops moving along with the inclined guide post 6 through the second limiting block 9, the second limiting block 9 is a limiting stopper, a spring is arranged below the limiting stopper, and the limiting stopper touches the second limiting clamping groove 32 to play a limiting role.

Furthermore, a second limiting screw 13 is arranged on the die. The second limit screw 13 prevents the outer slide core fixing base 3 from flying out.

Furthermore, a cooling water pipe (not shown) is arranged on the inner slide core fixing seat 2. In the inside slider core 4, water-proof piece and hot exchange pipe have been used, have guaranteed the biggest cooling area, design 90 degrees return bends and connect the injection molding machine water route alone simultaneously on slider core fixing base 2 including, have guaranteed the independence and the cooling effect in water route.

The push plate 10 is pushed out under the drive of the KO column of the injection molding machine, and because a gap exists between the push plate 10 and the product, the push plate 10 can be empty-topped for a certain distance, and because the delay needle 11 is arranged below the ejector pin, under the action of the delay needle 11, the ejector pin plate is timely pushed by the KO column of the injection molding machine, the ejector pin can also keep the same distance as the gap between the push plate and the product, and then the ejector pin and the push plate can push out the product together.

Let inside and outside slider core not need the order to withdraw from, interior slider core 4 withdraws from a few millimeters earlier, because the product inboard can not be strained to the removal more, because the gluey position of interior slider core 4 is tapered, and after withdrawing from, there is the clearance in gluey position and interior slider core 4, and the product inboard just has not had the rubber coating power when outer slider core 5 withdraws from again, has also had deformation space, and outer slider core 5 just can withdraw from smoothly to can not strain the outside gluey position.

The foregoing is only a preferred embodiment of the present invention, and it should be noted that, for those skilled in the art, a plurality of modifications and variations can be made without departing from the technical principle of the present invention, and these modifications and variations should also be considered as the protection scope of the present invention.
