The utility model discloses the swinging direct ejection core pulling mechanism of a kind of injection mold, including guiding mold insert, straight push rod, tip-lever support；Described guiding mold insert is arranged on moving platen, and the lower end of straight push rod is hinged in tip-lever support, and the top movable of straight push rod is located in a top part as die cavity for guiding mold insert inside groove and straight push rod, and tip-lever support is fixedly mounted in top board.Owing to this utility model includes guiding several parts such as mold insert, straight push rod, tip-lever support, structure is relatively simple；Straight push rod of the present utility model is the motion of upright direction and can swing around tip-lever support, can deviate from back-off ejecting product through swing, and the problem so solving the slant-top core-pulling that is not easy to do owing to space is the least has saving die space, the advantage such as is convenient to process and mount.
Description
Technical field
This utility model relates to a kind of injection mold, particularly relates to the swinging direct ejection core pulling mechanism of a kind of injection mold.
Background technology
Plastics injection mould is the instrument producing plastic, and application is widely.In plastic injection mo(u)lding, by
Having indent in the inside of some plastic, need to carry out side core-pulling, the core-pulling mechanism commonly used is required for greatly the portions such as Angle Pin
Part, structure is complex, takes up room bigger.
Summary of the invention
The purpose of this utility model is to provide the swinging direct ejection of the injection mold that a kind of simple in construction, die space are little to take out
Core mechanism.
For achieving the above object, technical solution of the present utility model is:
This utility model is the swinging direct ejection core pulling mechanism of a kind of injection mold, including guiding mold insert, straight push rod, push rod
Seat；Described guiding mold insert is arranged on moving platen, and the lower end of straight push rod is hinged in tip-lever support, and the top movable of straight push rod is worn
Being located at a top part as die cavity for guiding mold insert inside groove and straight push rod, tip-lever support is fixedly mounted in top board.
Described guiding mold insert is made up of left guiding mold insert and right guiding mold insert, and left guiding mold insert and right guiding mold insert are fixed
In being arranged on moving platen and relatively setting, left guiding mold insert and right guiding mold insert medial wall are convex recessed cascaded surface；Described
Straight push rod is made up of two left straight push rods relatively set and the straight push rod in the right side, and the lower end of left straight push rod and the straight push rod in the right side is passed through respectively
Hinge is on tip-lever support, and the top outer of left straight push rod and the straight push rod in the right side is all provided with the groove as button bit, left straight push rod
The top movable of push rod straight with the right side is located in the inside groove of left guiding mold insert and right guiding mold insert composition and left directly push rod and the right side are straight
The top of push rod as a part for die cavity, the upper outside step surface of left straight push rod and the straight push rod in the right side respectively with left guiding mold insert
Lean with right guiding mold insert medial wall cascaded surface.
After using such scheme, owing to this utility model includes guiding several parts such as mold insert, straight push rod, tip-lever support, knot
Structure is relatively simple；Straight push rod of the present utility model is the motion of upright direction and can swing around tip-lever support, can take off through swinging
Go out back-off ejecting product, the problem so solving the slant-top core-pulling that is not easy to do owing to space is the least, there is saving die space, add
The advantages such as work is easy for installation.
With specific embodiment, this utility model is further described below in conjunction with the accompanying drawings.
Accompanying drawing explanation
Fig. 1 is axonometric drawing of the present utility model；
Fig. 2 is application example figure of the present utility model.
Detailed description of the invention
As it is shown in figure 1, this utility model is the swinging direct ejection core pulling mechanism of a kind of injection mold, including guiding mold insert 1, directly
Push rod 2, tip-lever support 3, bearing pin 4.
Described guiding mold insert 1 is made up of left guiding mold insert 11 and right guiding mold insert 12, left guiding mold insert 11 and right guiding
In mold insert 12 is fixedly mounted on moving platen 5 and relatively setting, left guiding mold insert 11 and right guiding mold insert 12 medial wall are convex recessed
Cascaded surface 111,121.
Described straight push rod 2 is made up of two left straight push rods 21 relatively set and the straight push rod in the right side 22, left straight push rod 21 He
The lower end of right straight push rod 22 is hinged on tip-lever support 3 by bearing pin 4 respectively, left straight push rod 21 and the top outer of the straight push rod in the right side 22
All being provided with the groove 211,221 as button bit, the upper outside of left straight push rod 21 and the straight push rod in the right side 22 is shunk and shape respectively inwards
Becoming a step surface 212,222, the top movable of left straight push rod 21 and the straight push rod in the right side 22 is located in left guiding mold insert 11 and the right side is led
In the inside groove that mold insert 12 is constituted and the top of left straight push rod 21 and the straight push rod in the right side 22 is as the part of die cavity, left straight push rod 21
The upper outside step surface of push rod 22 straight with the right side respectively with left guiding mold insert 11 and right guiding mold insert 12 medial wall cascaded surface 111,
121 lean.
Described tip-lever support 3 is fixedly mounted in top board 6.
Operation principle of the present utility model:
As shown in Figure 1 and Figure 2, when die sinking, left straight push rod 21 and the right side straight push rod 22 after ejecting 20mm, left straight push rod 21
The upper outside step surface 212,222 of push rod 22 straight with the right side is at left guiding mold insert 11 and right guiding mold insert 12 medial wall cascaded surface
111, the top pressure of 121 can inwardly swing 1mm, i.e. left straight push rod 21 and the straight push rod in the right side 22 can mutually be drawn close so that left straight push rod
21 and the top outer of the straight push rod in the right side 22 depart from the button bit of product 10 as the groove 211,221 of button bit, and smoothly ejecting product
10。
Emphasis of the present utility model is that and uses swingable straight push rod structure.
The above, only this utility model preferred embodiment, therefore can not limit what this utility model was implemented with this
Scope, the equivalence change i.e. made according to this utility model claim and description and modification, all should still belong to this reality
In the range of containing with new patent.
