Abstract

The utility model relates to a kind of thimble exhaust structures of plastic mould, including preceding mould, rear mold, type chamber, gas cap, thimble, spring, the type chamber is in caudacoria, the thimble is located at type chamber front end, and thimble and type chamber are integrally formed, the gas cap is socketed on the outside of thimble, and the spring is located in gas cap.The utility model benefit both optimizes mold design, break the limitation of conventional exhaust design position, will not result in blockage again and be difficult to clear up, the gas in type chamber can be smoothly discharged from the groove designed in thimble, make product will not because be vented it is unsmooth due to the bad phenomenons such as cause trapped gas, burn, in addition the dust cap of equipment addition, the further tight anti-dust performance for increasing equipment, structure is simple, and material is common, facilitate manufacture, preferably promotes the use of.

Description

A kind of thimble exhaust structure of plastic mould

Technical field

The utility model relates to mould manufacturing field more particularly to a kind of thimble exhaust structures of plastic mould.

Background technique

In plastic mould design, traditional exhaust mode is exactly to design air discharge duct, but have the place much limited to, It is generally located in stream end or the larger position of plastic wall thickness.It is exactly that die joint gap is utilized to be vented there are also a kind of mode, still This mode also has at a limitation, and the time has been grown may block later, also wants periodic cleaning.Both the above exhaust mode is all With certain limitation, maximum exhaust effect can not achieve.

Utility model content

The purpose of this utility model is to provide a kind of thimble exhaust structures of plastic mould, are asked with solving above-mentioned technology Topic, the utility model uses following technical scheme to achieve the above object:

A kind of thimble exhaust structure of plastic mould, including preceding mould, rear mold, type chamber, gas cap, thimble, spring, the type chamber In caudacoria, the thimble is located at type chamber front end, and thimble and type chamber are integrally formed, and the gas cap is socketed on the outside of thimble, The spring is located in gas cap.

On that basis of the above technical scheme, the thimble rear end is equipped with annular external groove, and the gas cap rear end is equipped with annular Inner groovy, the thimble side is equipped with bulge loop and scarce item mouth, and the scarce item mouth of thimble is not contacted with the inner wall of gas cap.

On that basis of the above technical scheme, the gas cap rear end is equipped with internal projecting ring and outer bulge loop, and the internal projecting ring contacts bullet Spring tail end, outer bulge loop outside are equipped with dust cap.

On that basis of the above technical scheme, the gas cap, thimble, type chamber are made of brass material, the preceding mould, after Mould, dust cap are made of rubber material, and the spring is made of carbon steel material.

Compared with prior art, the utility model has the advantage that the utility model benefit both optimizes mold design, breaks The limitation of conventional exhaust design position, and will not result in blockage and be difficult to clear up, the gas in type chamber can be designed out of thimble Groove in be smoothly discharged, make product will not because be vented it is unsmooth due to the bad phenomenons such as cause trapped gas, burn, in addition equipment addition Dust cap, the further tight anti-dust performance for increasing equipment, structure is simple, and material is common, facilitates manufacture, preferably promotes the use of.

Specific embodiment

The utility model is further elaborated in the following with reference to the drawings and specific embodiments.

A kind of thimble exhaust structure of plastic mould, including preceding mould 2, rear mold 1, type chamber 7, gas cap 4, thimble 3, spring 6, institute Type chamber 7 is stated in caudacoria 2, the thimble 3 is located at 7 front end of type chamber, and thimble 3 and type chamber 7 are integrally formed, 4 sets of the gas cap It connects in 3 outside of thimble, the spring 6 is located in gas cap 4.

3 rear end of thimble is equipped with annular external groove 8, and 4 rear end of gas cap is equipped with interior annular groove 9,3 side of thimble Face is equipped with flange collar 11 and scarce item mouth 10, and the scarce item mouth 10 of thimble 3 is not contacted with the inner wall of gas cap 4.

4 rear end of gas cap is equipped with internal projecting ring 12 and outer bulge loop 13,12 contact spring of internal projecting ring, 6 tail end, outer bulge loop 13 outsides are equipped with dust cap 5.

The gas cap 4, thimble 3, type chamber 7 are made of brass material, and the preceding mould 1, rear mold 2, dust cap 5 are by rubber Material is made, and the spring 6 is made of carbon steel material.

Utility model works principle: when using equipment, being mounted at port, when needing to discharge the air pressure in mold, Dust cap is removed, the rear end of air compressing cap is then pressed, spring receives compression at this time, and gas cap is moved to close to cavity side, herein mistake Cheng Zhong, annular external groove and interior annular groove are close to each other, and when repeating completely and being opposite, the air pressure in mold is released, Gas in mold is flowed in interior annular groove and annular external groove by type chamber, then thinks external eruption by but item mouth, works as release After finishing, gas cap top Hui Yuanwei, gas cap and bulge loop are in close contact by spring, thus sealed mold.

The above is the utility model preferred embodiment, for the ordinary skill in the art, according to this reality With novel introduction, in the case where not departing from the principles of the present invention and spirit, the change that is carried out to embodiment is repaired Change, replacement and variant is still fallen within the protection scope of the utility model.
