Description
Technical field
The utility model relates to injection mold fields, more particularly to a kind of pneumatic jack structure of injection mold.
Background technique
It is smoothly produced in order to facilitate product, pneumatic jack is widely used in injection mold.But traditional pneumatic jack structure because
Inclined-plane cooperation, when production, need very high machining accuracy.Pressure in injection moulding process squeezes pneumatic jack core constantly in pneumatic jack,
Or the deformation after temperature raising, all pneumatic jack core can be caused to be stuck, smoothly be demoulded to influence product, and failure repeatedly is not
Production efficiency is only influenced, causes to waste, the damage of mold and other equipment is even caused when serious.
Summary of the invention
The technical problem to be solved by the utility model is to provide a kind of pneumatic jack structures of injection mold, and structure is simple, move
Without clamping stagnation when making, the stability for improving production avoids maintenance caused by pneumatic jack Block failure and its therefore damages to equipment bring
Evil.
Technical solution adopted by the utility model to solve its technical problems is：A kind of pneumatic jack knot of injection mold is provided
Structure, including the gentle plunger tip of pneumatic jack ontology, the inside of the pneumatic jack ontology are axially disposed with pneumatic jack core bore gentle plunger tip hole one end
Limit inner hole, the pneumatic jack core is inserted into pneumatic jack core bore, and one end of the pneumatic jack core, which is disposed with, to be located in limit inner hole
The two sides of base station, the limit inner hole have been arranged symmetrically kidney slot, are horizontally through in the base station and are disposed with pin, described
The both ends of pin be inserted into corresponding kidney slot, the two sides of the pneumatic jack core have been arranged symmetrically plane groove, described
It is socketed with one end on the outside of pneumatic jack core to withstand with base station, the spring that the other end is withstood with pneumatic jack core bore inside side walls.
As a kind of supplement, lateral arrangement has grafting through-hole in the base station, and the pin is inserted into grafting through-hole
It is interior.
Further, it is disposed with a ring slot on the outside of the end of the pneumatic jack core, which is connected with plane groove.
Beneficial effect：The utility model relates to a kind of pneumatic jack structures of injection mold, and structure is simple, abandoning tradition pneumatic jack core
Inclined design carried out under the action of compressed air and spring straight using pneumatic jack core and the direct shaft hole matching of pneumatic jack ontology
The manner of execution directly gone out, in ejection movement, compressed air is flowed through by the processing gap of pneumatic jack core and pneumatic jack ontology, when movement
Without clamping stagnation, the stability for improving production avoids maintenance caused by pneumatic jack Block failure and its therefore damages to equipment bring.
Detailed description of the invention
Fig. 1 is that the utility model does not eject the half-sectional structure chart of state main view；
Fig. 2 is the half-sectional structure chart of ejection state main view of the utility model；
Fig. 3 is the main structure figure of pneumatic jack core described in the utility model；
Fig. 4 is the half-sectional structure chart of main view of pneumatic jack ontology described in the utility model.
Specific embodiment
The present invention will be further illustrated below in conjunction with specific embodiments.It should be understood that these embodiments are merely to illustrate this
Utility model rather than limitation the scope of the utility model.In addition, it should also be understood that, in the content for having read the utility model instruction
Later, those skilled in the art can make various changes or modifications the utility model, and such equivalent forms equally fall within this Shen
It please the appended claims limited range.
As shown in Figs 1-4, the embodiments of the present invention is related to a kind of pneumatic jack structure of injection mold, including pneumatic jack sheet
The gentle plunger tip 2 of body 1, the inside of the pneumatic jack ontology 1 are axially disposed in the limit of gentle 8 one end of plunger tip hole of pneumatic jack core bore 8
Hole 7, the pneumatic jack core 2 are inserted into pneumatic jack core bore 8, and one end of the pneumatic jack core 2 is disposed with the base station being located in limit inner hole 7
6, the two sides of the limit inner hole 7 have been arranged symmetrically kidney slot 4, are horizontally through in the base station 6 and are disposed with pin 5, institute
The both ends for the pin 5 stated are inserted into corresponding kidney slot 4, and the two sides of the pneumatic jack core 2 have been arranged symmetrically plane groove 9,
The outside of the pneumatic jack core 2 is socketed with one end and withstands with base station 6, the spring that the other end is withstood with 8 inside side walls of pneumatic jack core bore
3。
In the movement for ejecting and resetting, limited by the cooperation of pneumatic jack ontology and pin.
As a kind of supplement, lateral arrangement has grafting through-hole 11 in the base station 6, and the pin 5 is inserted into grafting
In through-hole 11.
Further, it is disposed with a ring slot 10 on the outside of the end of the pneumatic jack core 2, the annular groove 10 and plane groove 9
It is connected, guarantees the mobility of high pressure gas.
The utility model structure is simple, the inclined design of abandoning tradition pneumatic jack core, direct using pneumatic jack core and pneumatic jack ontology
Shaft hole matching carries out the straight manner of execution directly gone out under the action of compressed air and spring, in ejection movement, compressed air
It is flowed through by the processing gap of pneumatic jack core and pneumatic jack ontology, without clamping stagnation when movement, the stability for improving production avoids pneumatic jack clamping stagnation
It repairs caused by failure and its therefore equipment bring is damaged.
