Abstract
The utility model provides a mold which adopts the following structure and is used for manufacturing a corrugated pipe. The mold comprises a pair of mold bodies provided with symmetrical semi-circular arc chutes, wherein circumferentially distributed corrugated grooves are formed in the inner walls of the arc chutes in the mold; and the corrugated grooves are formed in the inner walls of the semi-circular arc chutes, and air seams which radially penetrate through two sides of the mold are distributed along the corrugated grooves in the mold.
Description
Technical field:
The utility model relates to a kind of bellows mfg. moulding die.
Background technology:
In prior art; the manufacturing technology of bellows is comparatively ripe; apply also more extensively, wherein the ripple struction on bellows is to match with outer mold by swing arm, rotation inside the Pass being inserted in manufacture process; body in mould is forced into to corrugated; the produced bellows of this mould structure is second-rate, and the inwall of bellows often there will be various flaws, affects the service property (quality) of bellows; and the mould of this structure, manufacture efficiency also lower.And in the bellows manufacture process, for guaranteeing the even running that can cooperatively interact of separate mould, needing to add proper lubrication oil between mould is lubricated, mould can avoid occurring inordinate wear in running, the problems such as heating, but due to mould all the time in moving process, therefore, lubricating oil is easy to be penetrated into from the gap between adjacent molds the inside of mould, for with less demanding product, a small amount of lubricating oil there is no big harm, but to some special products, such as being applied in Medical Devices, requirement to the bellows quality is just higher, the infiltration meeting of lubricating oil causes severe contamination to bellows, this contaminated bellows can't use at medical field.
The utility model content:
For solving above-mentioned technical problem, the utility model provides a kind of bellows mfg. moulding die that is conducive to improve the bellows cleannes.
The technical solution of the utility model is, a kind of a kind of bellows mfg. moulding die with following structure is provided, it comprises a pair of die body that is provided with symmetrical semi-circular arc groove, on die body, the inwall of arc groove is provided with the wave groove of circumferential arrangement, the inwall of semi-circular arc groove is provided with wave groove, arranges and radially run through the air cleft of die body both sides on described die body along wave groove.
Wherein, between the air cleft in described wave groove, be provided with supplementary air cleft in end, several air clefts in wave groove are linked to be multistage air cleft section through supplementing the air cleft air cleft that each is adjacent.
Moreover an end of described air cleft section is provided with the passage that runs through the die body both sides.
In addition, the arris of described die body is the rounding structure, and the lower end of die body is provided with the transmission teeth, and upper surface obtains both sides and is provided with the arc concave station for matching with slideway.
As improvement, described die body is provided with the oil strain groove.
Wherein, described oil strain groove is positioned at the two ends of die body.
After adopting said structure, the utlity model has following advantage:
After on mould, air cleft being set, by extraneous vacuum air pump, from die body go out bled, in the process of manufacturing bellows, by air cleft, realize die body inside is vacuumized, the plastic material entered in bellows just is attracted in wave groove, thereby formation bellows, the inwall of the bellows that this mode is made is very smooth, better quality, and production efficiency is also higher, the air cleft of space is linked to be to integral body and is conducive to improve the vacuum suction effect, be conducive to the moulding of ripple, teeth on die body and concave station all are conducive to the steady transmission of die body.And after corrugated pipe forming groove surrounding is arranged the oil strain groove, from inward the infiltration lubricating oil will be blocked by this oil strain groove, can not enter in the corrugated pipe forming groove, can not pollute product, the cleannes of product are also just higher, just can meet the instructions for use in medical treatment.
The accompanying drawing explanation:
The side view that Fig. 1 is the utility model bellows mfg. moulding die;
The front view that Fig. 2 is the utility model bellows mfg. moulding die;
The rear view that Fig. 3 is the utility model bellows mfg. moulding die;
The upper surface view that Fig. 4 is the utility model bellows mfg. moulding die;
The lower surface view that Fig. 5 is the utility model bellows mfg. moulding die.
The specific embodiment:
Below in conjunction with drawings and the specific embodiments, the utility model is described in further detail.
As shown in Figure 1, Figure 2, shown in Fig. 3, Fig. 4, Fig. 5, the utility model bellows mfg. moulding die, it comprises a pair of die body 2 that is provided with symmetrical semi-circular arc groove 1, on die body 2, the inwall of arc groove 1 is provided with the wave groove 3 of circumferential arrangement, the inwall of semi-circular arc groove 1 is provided with wave groove 3, it is characterized in that: the air cleft 4 of arranging and radially run through die body 2 both sides on described die body 2 along wave groove 3.
Wherein, be the effect that raising vacuumizes, be provided with in end between the air cleft 4 in wave groove 3 and supplement air cleft 5, several air clefts 4 in wave groove 3 are linked to be multistage air cleft section through supplementing air cleft 5 air cleft 4 that each is adjacent.
Further, the end in described air cleft section is provided with the passage 6 that runs through die body 2 both sides.
For adapting to the improvement of applicant to the die body chute, the arris of die body 2 is to the rounding structure, the lower end of die body 2 is provided with transmission teeth 7, upper surface obtains both sides and is provided with the arc concave station 8 for matching with slideway, certainly, in die body 2 lower surface side one sides, arc concave station 8 also is set, such purpose is to guarantee that die body 2 keeps stable in transport process.
For avoiding the pollution of lubricating oil to product, described die body 2 is provided with oil strain groove 9.Wherein, oil strain groove 9 is positioned at the two ends of die body 2.From die body 2, the lubricating oil of infiltration will be blocked by this oil strain groove inward, can not enter in the corrugated pipe forming groove, can not pollute product, and the cleannes of product are also just higher, just can meet the instructions for use in medical treatment.
