Product external surfaces are directly acted on by thimble, thimble is plastic mould accessory, in plastic mould, thimble can also to be named and be pushed away
Bar, pin, middle needle, support needle etc., in the prior art, since thimble is metal material, directly being impacted to injection product surface can make
It is damaged at product surface, patent announcement number is：The utility model patent of 206952042 U of CN uses shock-proof spring and dish
Spring, but the balance of disc spring is poor, cannot ensure thimble position well, simultaneously as thimble is in a mold in use, oil
Dirt easily corrodes thimble, reduces the service life.
Utility model content
In order to solve the above technical problems, the utility model proposes a kind of adjustable thimble, including first body of rod and activity are pacified
Loaded on second body of rod in first body of rod, second body of rod stretches out first body of rod and bottom is equipped with sealing plate, institute
It states and is equipped with spring in first body of rod, the sealing plate is pressed on the spring, and the spring lower part is equipped with pushing block, on the pushing block
Equipped with air inlet, gas off-take is equipped in second body of rod, the gas off-take is connected to the sealing plate；First body of rod and
Horizontal limiting mechanism is equipped between second body of rod.
Preferably, the Horizontal limiting mechanism includes being located at the bulge loop of first body of rod inner wall, vertical in the bulge loop
It is provided with slot, second body of rod is equipped with fixture block, and the fixture block inserts in the slot.
Preferably, the sealing plate includes round plate body, and the circle plate body circumference is equipped with rubber ring.
Preferably, first body of rod and second body of rod outer wall are equipped with polytetrafluoroethylene ethylene layer.
Preferably, first rod end is equipped with limited block.
The utility model proposes adjustable thimble have following advantageous effect：1, used polytetrafluoroethylene (PTFE) as coating, energy
The outer greasy dirt of enough quickly erasing thimbles；2, using spring and Horizontal limiting mechanism, when can ensure that second body of rod is up and down, newspaper
Crooked, while spring its cushioning effect does not occur, prevents from directly impacting product, damages product surface for vertical state；3, it especially sets
Induction part has been set, can will not damage product surface from the second mandril center outlet convenient for exiting thin-wall product.

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；
Fig. 2 is first body of rod sectional view of the utility model；
Fig. 3 is the jack-up status diagram of the utility model；
Wherein, 1, first body of rod；2, second body of rod；3, sealing plate；4, spring；5, pushing block；6, air inlet；7, gas off-take；
8, bulge loop；9, fixture block；10, slot；11, polytetrafluoroethylene ethylene layer；12, limited block.
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 FIG. 1 to 3, it the utility model proposes a kind of adjustable thimble, including first body of rod 1 and is movably installed in
Second body of rod 2 in first body of rod 1, second body of rod 2 stretches out first body of rod 1 and bottom is equipped with sealing plate 3,
Spring 4 is equipped in first body of rod 1, the sealing plate 3 is pressed on the spring 4, and 4 lower part of the spring is equipped with pushing block 5, institute
It states pushing block 5 and is equipped with air inlet 6, be equipped with gas off-take 7 in second body of rod 2, the gas off-take 7 is connected to the sealing plate 3；
Horizontal limiting mechanism is equipped between first body of rod 1 and second body of rod 2.
The working method of the utility model is：Thimble is installed in mold, is fixed on jacking mechanism, jacking mechanism pushes away
It moves entire first body of rod 1 to move upwards, realizes primary jack-up, if desired when Double-ejection, lower part pushes pushing block 5, pushes second
The body of rod 2, second body of rod 2 peak on injecting products, product are ejected, and in first body of rod, 1 end set limited block 12, are convenient for mould
Plate positions first body of rod 1, limits the distance pushed for the first time, is convenient for the promotion of secondary jack-up, the secondary work pushed due to spring 4
With being buffered when second body of rod 2 can be made to move upwards, will not directly impact product surface, cause rigid damage, together
When, for the ejection suitable for thin-wall product, thin-wall product thimble impact not easy to use, in second body of rod, 2 centrally disposed outlet
