Description
Technical field
The present invention relates to a kind of demoulding mechanism more particularly to a kind of oblique slot type impeller core-drawing demoulding mechanisms three times.
Background technique
For trade effluent irrigation and drainage machine impeller plastic, the internal groove impeller injection molding based on fluid mechanical design is tired
Difficulty, main problem are the molded part difficult designs of impeller, and mold is difficult to manufacture；Focal issue is the molding of impeller inside groove and takes off
Mould, mechanism design improper or will need bigger die carrier structure space, so, the cost of mold will sharply increase.
Structure mold temporarily without such plastic and respective leaves slot demoulding mechanism in the prior art.Or have, substantially use
Oil cylinder driving or motor driven realize the molding and demoulding of plastic leaf slot, certainly will increase the complex degree of structure of mold, mould
Tool cost certainly will sharply increase.
Summary of the invention
The present invention provides oblique slot type impeller core-drawing demoulding mechanisms three times, make full use of the die sinking power of mold, pass through machine
The transmitting of tool power, to drive the oblique type core core pulling positioned at dynamic model side, mechanism is installed on the inside of mold dynamic model side, uses
Substep is delayed to carry out the core pulling of leaf slot.
The present invention provides oblique slot type impeller core-drawing demoulding mechanism, including inclined guide pillar three times, the inclined guide pillar is arranged with
One sliding block, the inclined guide pillar are arranged with the second sliding block, second sliding block below first sliding block, first sliding block and
Second sliding block joint is formed with cavity, and spring is provided in the cavity, and the spring one end connects first sliding block, institute
It states the spring other end and connects second sliding block, second sliding block lower surface is provided with the first groove and the second groove, described
Inclined guide pillar is arranged with third sliding block, and below second sliding block, the third sliding block connects the third sliding block with the second sliding block
The face of touching, which is provided with, dials pearl, and the third sliding block is arranged with curved pin, and the curved inclined protrusion in pin upper end is plugged in described the
Three sliding blocks, the curved pin are fixed on bottom plate.
The first sliding block and the movement of the second sliding block is driven to be demoulded by inclined guide pillar, since plastic needs core pulling simultaneously, no
Product can be so destroyed, therefore the movement of curved pin drives the movement of third sliding block, third sliding block will drive the first sliding block and second and slide
Block movement, finally by product core pulling simultaneously.
The present invention is further, and the direction of the first sliding block sliding is provided with the first banking pin.
The present invention is further, and the direction of the third sliding block sliding is provided with the second banking pin.
The present invention is further, is provided with the first latch segment on first sliding block.
The present invention is further, is provided with the second latch segment on the third sliding block.
Oblique slot type impeller provided by the invention core-drawing demoulding mechanism three times, makes full use of the die sinking power of mold, passes through machine
The transmitting of tool power, to drive the oblique type core core pulling positioned at dynamic model side, mechanism is installed on the inside of mold dynamic model side, uses
Substep is delayed to carry out the core pulling of leaf slot, realizes the automation injection molding production of plastic, mechanism occupancy mould bases space is small, processing and fabricating
It is convenient, advantageously reduce the manufacturing cost of mold.
Detailed description of the invention
Fig. 1 is the schematic diagram of oblique slot type impeller core-drawing demoulding mechanism and plastic three times.
Specific embodiment
With reference to the accompanying drawing, it elaborates to a specific embodiment of the invention.
As shown in Figure 1, oblique slot type impeller core-drawing demoulding mechanism, including solid plate 1 three times, the solid plate 1 are connected with tiltedly
Guide post 2, the inclined guide pillar 2 are arranged with the first sliding block 3, and the first latch segment 14, first lock are provided on first sliding block 3
Tight block 14 is connected on solid plate 1, and when not being opened, the first latch segment 14 can head on the first sliding block 3 and be fixed on plastic A
On, the direction that first sliding block 3 slides is provided with the first banking pin 6, plays the role of limit.The inclined guide pillar 2 is arranged with
Second sliding block 5,3 below first sliding block, first sliding block 3 and 5 joint of the second sliding block are formed second sliding block 5
There is cavity, spring 4 is provided in the cavity, described 4 one end of spring connects first sliding block 3, and 4 other end of spring connects
Second sliding block 5 is connect, 5 lower surface of the second sliding block is provided with the first groove 9 and the second groove 10, second sliding block 5
On be provided with the second latch segment 15, second latch segment 15 is connected to solid plate 1, and when not having on-mode, the second latch segment 15 can
It is fixed on plastic A with heading on the second sliding block 5, the direction that second sliding block 5 slides is provided with the second banking pin 11, plays limit
The effect of position.The inclined guide pillar 2 is arranged with third sliding block 7, and the third sliding block 7 is below second sliding block 5, the third
The face that sliding block 7 is contacted with the second sliding block 5, which is provided with, dials pearl 8, the specification phase of described group of pearl 8 and the first groove 9, the second groove 10
Symbol, the third sliding block 7 are arranged with curved pin 12, and the inclined protrusion in curved 12 upper end of pin is plugged in the third sliding block 7, institute
Curved pin 12 is stated to be fixed on bottom plate 16.
For oblique slot type impeller plastic A, as shown in Figure 1, inclined guide pillar 2 can be moved up, inclined guide pillar 2 when die sinking
It will drive the first sliding block 3 to be moved to the left, can not be moved since spring 4 does not reach maximum elastic second sliding block 5, when the first sliding block
3 stoppings when being moved to the first banking pin 6, which carries out first time demoulding, when inclined guide pillar 2 is moved upwards up to one
When positioning is set, the tail end of inclined guide pillar 2 can encounter the second sliding block 5, since spring 4 is moved to maximum bullet by the first sliding block 3
Property, the movement of the second sliding block 5 is also hauled, second sliding block 5, due to there is overhead kick on plastic A, can need past up and toward moving left
On lift and can just demould, therefore the second sliding block 5 realizes second of demoulding, and it is recessed that described group of pearl 8 from the first groove 9 reaches second
It can achieve limit when slot 10.When last curved pin 12 moves down with bottom plate 16, third sliding block 7 past can be moved left, by
It is limited in the first sliding block 3 and the second sliding block 5, plastic A is reached whole demouldings by no sufficient space, and sliding 7 pieces of third will drive
First sliding block 3 and the second sliding block 5 are completed third time and are demoulded, finally demould plastic A completely toward moving left.
Mechanism makes full use of the die sinking power of mold, by the transmitting of mechanical force, to drive positioned at the oblique of dynamic model side
To type core core pulling, mechanism is installed on the inside of mold dynamic model side, and the core pulling of leaf slot is carried out using substep delay, realizes plastic
Automation be molded production, mechanism occupies that mould bases space is small, and processing and fabricating is convenient, advantageously reduces the manufacturing cost of mold.
