Specific embodiment
It, below will knot to enable the purpose of utility model, feature, advantage of the utility model more obvious and understandable
The attached drawing in the utility model embodiment is closed, the technical scheme in the utility model embodiment is clearly and completely described,
Obviously, the embodiments described below are only the utility model a part of the embodiment, and not all embodiment.Based on this reality
It is obtained by those of ordinary skill in the art without making creative efforts all other with the embodiment in novel
Embodiment is fallen within the protection scope of the utility model.
Further illustrate the technical solution of the utility model below with reference to the accompanying drawings and specific embodiments.
In the description of the present invention, it should be understood that term " on ", "lower", "top", "bottom", "inner", "outside" etc.
The orientation or positional relationship of instruction is to be based on the orientation or positional relationship shown in the drawings, and is merely for convenience of description the utility model
It is described with simplifying, rather than the device or element of indication or suggestion meaning must have a particular orientation, with specific orientation structure
It makes and operates, therefore should not be understood as limiting the present invention.
It please refers to shown in Fig. 1-3, a kind of mechanism for preventing core pulling from falling back, including core pulling 2 and slide 9, the core pulling 2 tilt
Be slidably mounted in core bore 13, and core bore 13 inclination be provided on 1 outer surface corresponding position of insert, described 13 one end of core bore with
Corresponding 8 bottom of sliding slot connection, and sliding slot 8 is provided with 3 top side surface of mold, 2 one end end face of core pulling offer the
One horizontal plane 12 and the first inclined-plane 10；
The slide 9 is slidably mounted in sliding slot 8, and 9 one end end face of slide is mounted on 7 one end of push rod, 9 bottom of slide
Portion is equipped with the second horizontal plane 4 and the second inclined-plane 11, and 7 other end of push rod in piston and oil cylinder 6 by being slidably connected, and oil cylinder
6 are mounted on 5 side of take-up housing.
3 side of mold offers the structure grooves 301 of corresponding construction, and structure grooves 301 and insert 1 mutually inlay company
It connects, the installation convenient for insert 1 is fixed；8 internal structure of sliding slot is consistent with 9 structure matching of slide, ensure that phase between the two
To the consistency of sliding fitting；The angle that described 12 one end of first level face and 10 one end of the first inclined-plane intersect to form is equal to second
The angle that 4 one end of horizontal plane and 11 one end of the second inclined-plane intersect to form staggeredly reclines convenient for the movement between subsequent respective face；Institute
It states 5 one end of take-up housing to be mounted on 3 side side corresponding position of mold, is conducive to erect the oil cylinder 6 for being located at side and fix；
The corresponding space of the mold 3 and insert 1 form an injection molding space, and are molded the internal structure and product structure one in space
It causes, is convenient for subsequent injection molding.
When the utility model is used, the oil cylinder 6 shunk by operation drives push rod 7 to move backward, it is connected to drive
The slide 9 for connecing end also moves backward, and the second horizontal plane 4 is gradually separated with first level face 12 at this time, and first level face 12 with
The first inclined-plane 10 rib end that interlocks starts sliding and sticks on the second inclined-plane 11 until separation between each other so that the second inclined-plane 11 with
First inclined-plane 10 mutually reclines, and the core pulling 2 at 10 end of the first inclined-plane at this time also slowly protrudes into cunning under the action of corresponding external force simultaneously
In slot 8, to achieve the effect that core pulling 2 is extracted out, the second inclined-plane 11 and 9 side of slide are acted against to the vertical stress in the first inclined-plane 10
Staggeredly on rib end, and oil cylinder 6 remain stationary state, thus be conducive to that core pulling 2 is avoided to retreat, and component is not present in 2 stress of core pulling,
Traditional structure is changed to 2 stress condition of core pulling, the reset of core pulling 2 is carried out by opposite mode of operation.
