Description
Technical field
The utility model belongs to technical field of mold, and in particular to a kind of ejecting mechanism of silica gel mould.
Background technology
Silicon moulds can use reaction formable plastics to carry out type vacuum injecting and forming after completing, and answer prototype exemplar
System, obtains the plastic part of small lot, process is as follows:Silicon moulds upper die and lower die are tightly molded and are bound with adhesive tape by 1；2
Calculate and weigh moulding material (generally two component polyurethane) according to the size of part, and by its A, B two groups be respectively put into A, B
In two containers, container A, B are placed in above type vacuum injecting and forming machine and Silicon moulds are placed below, connect material injection pipe, close the door and take out
Vacuum；3 mix the formable plastics in two containers of A, B, Silicon moulds, and Open valve immediately are injected after stirring, by one
Atmospheric pressure makes material be full of Silicon moulds；4 are put into curing oven and cure, and are kept for a period of time with certain temperature；After 5 solidifications,
It opens Silicon moulds and obtains vacuum injection part.
After obtaining injection-moulded plastic part, part sticks on mold, needs to be demoulded, be manually demolded it is time-consuming and laborious, so need
It is demoulded by the way of automation.

Description of the drawings
It is required in being described below to embodiment in order to illustrate more clearly of the technical scheme in the embodiment of the utility model
Attached drawing to be used is briefly described.
Fig. 1 is the structural schematic diagram of the utility model；
Wherein, 1, pushing mechanism；11, crank；12, disk；13, second connecting rod；2, ejecting unit；21, wedge block；22、
Spring；23, washer；3, lower die；4, pedestal；5, upper mold.
Specific implementation mode
The following will be combined with the drawings in the embodiments of the present invention, carries out the technical scheme in the embodiment of the utility model
Clearly and completely describe.
As shown in Figure 1, the utility model proposes a kind of ejecting mechanism of silica gel mould, ejecting mechanism is located at silica gel mould
Lower die 3 lower section, including multiple ejecting units 2, ejecting unit 2 includes washer 23, first connecting rod and wedge block 21, and first connects
Bar one end connects washer 23, and the other end connects wedge block 21, washer 23 be used for the feature contacts that process, in order not to accidentally injure zero
Part surface, washer 23 use flexible material.
Connecting rod passes through spring 22,22 one end of spring to be connect with 3 plate of lower die, and the other end is connect with wedge block 21, passes through setting
Spring 22 can provide the power moved downward to ejecting unit 2.
Pushing mechanism 1 is arranged in the lower section of each ejecting unit 2, and rotatable disk 12 is arranged in the top of pushing mechanism 1,
Disk 12 is opposite with the lozenges of wedge block 21, and disk 12 is connect with crank 11, connects by second between adjacent pushing mechanism 1
Bar 13 connects, and any crank 11 is connect with motor, drives crank 11 to rotate by the output end rotation of motor, passes through second connecting rod
13 drive all cranks 11 to do synchronous rotary motion.
The groove for placing washer 23 is arranged in the upper surface of lower die 3, and the depth of groove is equal with 23 thickness of washer, works as pad
When circle 23 drops to groove location, the extreme lower position of the movement of ejecting unit 2 is limited.
Pedestal 4 is arranged in the lower section of lower die 3, through-hole is arranged on pedestal 4, wedge block 21 passes through through-hole, in about 2 ejecting unit
During movement, wedge block 21 will slide up and down in through-hole, and through-hole limits the track of the movement of ejecting unit 2.
Motion mode：
After the completion of part injection molding, when need to be taken out from silica gel mould, connecting motor makes one of crank 11 rotate,
Due to the effect of second connecting rod 13, all cranks 11 is driven to rotate together, when rotating to disk 12 and wedge block on crank 11
21 lozenges contact when, disk 12 by hold up wedge block 21 move upwards, wedge block 21 head on first connecting rod and washer 23 to
Upper movement leaves lower die 3 to lift part, and part no longer sticks in lower die 3, and spring 22 is compressed at this time；
When crank 11 bypasses, wedge block 21 will decline under the action of 22 power of its own gravity and spring, until it is attributed to original flavor,
When needing demoulding again next time, this step is repeated.
A variety of modifications of embodiment will be apparent to those skilled in the art, determine herein
The General Principle of justice can be realized in other embodiments without departing from the spirit or scope of the present utility model.Cause
This, the utility model is not intended to be limited to the embodiments shown herein, and is to fit to and principles disclosed herein
The widest range consistent with features of novelty.
