Description
Technical field
The utility model is related to injection-moulding device technical field, specifically a kind of multistage undercut machine for injection mold
Structure.
Background technology
Injection is a kind of method that industrial products produce moulding.Product is usually using rubber injection mold and plastic injection.Injection
Can also dispensing molding die platen press and casting die.Injection (mo(u)lding) machine (abbreviation injector or injection machine) is by thermoplastic or heat
Solidity material is made the main former of variously-shaped plastic products using mould for plastics, and injection moulding is by injection
Machine and mould are realized.
When the product of hole, groove or boss is contained in injection-molded work side, during die sinking, due to this some holes or concave and convex direction with it is de-
Mould trust it is inconsistent, interfered with core and cannot the normally demoulding, now need to be completed using undercut mechanism, but
Existing undercut mechanism realizes function using Angle Pin mostly, but Angle Pin needs fine processing technology, it is desirable to essence
Degree is high, spends more.
Utility model content
The technical problems to be solved in the utility model is the defect for overcoming prior art, there is provided a kind of for injection mold
Multistage undercut mechanism.
In order to solve the above technical problems, the utility model provides following technical scheme：A kind of multistage for injection mold
Undercut mechanism, including：Fixing mould, vertical flexible mould, lateral flexible mould, chute, support plate, connecting rod, vertically tiltedly
The oblique split block of split block, level, described fixing mould matches with vertical flexible mould, lateral flexible mould, and described chute is consolidated
Fixing mould side is connected on, described lateral flexible mould is slidably connected on chute, and described support plate is fixed in vertical activity
On mould, described connecting rod top is connected on support plate, and described vertical oblique split block is fixed in connecting rod end, described water
Put down oblique split block and be fixed in lateral flexible mould side, the oblique split block of level matches with vertical tiltedly split block.
Further, described fixing mould side is connected with a column, and the side of described column is connected with a reset
Spring, the described back-moving spring other end is connected with lateral flexible mould.
Further, through hole is provided with described support plate, described connecting rod is slidably connected on support plate, is covered in connecting rod
There is compression spring, described compression spring two ends are connected with vertical tiltedly split block, support plate respectively.
Further, on described lateral flexible mould shrinkage pool or projection direction is level.
The utility model has an advantageous effect in that compared with prior art：
1. simple structure, cheap；
2. it is simple to operate, easy to use；
3. the release problems of side shaggy block are solved, and using effect is good.
The utility model has the advantages that simple structure, easy to use, using effect are good.
Brief description of the drawings
Fig. 1 is the utility model structural representation；
In figure marked as：1- fixing moulds；The vertical flexible moulds of 2-；The lateral flexible moulds of 3-；4- chutes；5- support plates；6-

Specific embodiment
In order that the purpose of this utility model, technical scheme and advantage become more apparent, below in conjunction with accompanying drawing and implementation
Example, is further elaborated to the utility model.It should be appreciated that specific embodiment described herein is only used to explain
The utility model, is not used to limit the utility model.
A kind of multistage undercut mechanism for injection mold as shown in Figure 1, including：Fixing mould 1, vertical activity
Mould 2, lateral flexible mould 3, chute 4, support plate 5, vertically connecting rod 6, the oblique split block 8 of oblique split block 7, level, described stent
Tool 1 matches with vertical flexible mould 2, lateral flexible mould 3, and described chute 4 is fixed in the side of fixing mould 1, described
Lateral flexible mould 3 is slidably connected on chute 4, and described support plate 5 is fixed on vertical flexible mould 2, described connecting rod 6
Top is connected on support plate 5, and described vertical oblique split block 7 is fixed in the end of connecting rod 6, and the oblique split block 8 of described level is fixed in
The lateral side of flexible mould 3, the oblique split block 8 of level matches with vertical tiltedly split block 7.
The described side of fixing mould 1 is connected with a column 9, and the side of described column 9 is connected with a back-moving spring 10,
The described other end of back-moving spring 10 is connected with lateral flexible mould 3, and back-moving spring 10 is acted on its own resilient, laterally
Flexible mould meeting 3 is opened, and the male and fomale(M＆F) of side surface of workpiece is separated with lateral flexible mould 3, you can carry out the demoulding；
Through hole is provided with described support plate 5, described connecting rod 6 is slidably connected on support plate 5, pressure is cased with connecting rod 6
Contracting spring 11, described two ends of compression spring 11 are connected with vertical tiltedly split block 7, support plate 5 respectively, and compression spring 11 can solve by
In the deformation that the influence such as temperature is caused, play a part of to protect mould；
