Abstract

The invention relates to a detachable residue-free core rod mould for a rubber pipe. A Z-shaped cutting track is designed according to a limiting position, namely a core rod is downwards cut along a limiting surface by the depth being 1/2 of the length of a bolt III, leftwards cut by the horizontal length exceeding the length of a positioning pin by 110-15 mm and downwards cut until the core rod is divided into two parts; the core rod is cut according to a linear cutting process and decomposed into a core rod I and a core rod II, and the positioning pin, a countersunk threaded hole, a positioning hole and a threaded hole are correspondingly formed in the plane after the cutting process. According to the mould, the core rod can be smoothly decomposed when residue is removed from the lower hoop of the core rod, so that the lower hoop is separated from the core rod and the purpose of simplicity in cleaning is achieved.

Description

Detachable without stub bar core rod mould

Technical field

The present invention relates to sebific duct Mould Machining field, particularly a kind of automotive hose with detachable without stub bar core rod mould.

Background technology

Automotive hose is used without stub bar mould, that iron hoop is welded on plug, by iron hoop, along plug, move axially and combine, although the sebific duct processing technology that is applied as without stub bar plug has solved stub bar waste problem, also reduced cutting action, improved working (machining) efficiency, but because hoop under plug is to be enclosed within mandrel tip, by what be welded and fixed, can not dismantle, cause without stub bar plug in coming into operation for a long time, be difficult to the defective material that remains in lower hoop inwall to clear, and each cleaning all will be cut iron hoop along cut surface, iron hoop is departed to plug, again welding again after cleaning defective material, as shown in Figure 1, iron hoop defective material after long-term use can be bonded on iron hoop inwall 5, and because iron hoop is enclosed within on plug, instrument can not enter iron hoop inwall and clear up, so must dismounting just can clear up, not only wastes time and energy but also increases cost.

The present invention is designed to plug detachable, solves problem as above.

Summary of the invention

The object of the present invention is to provide a kind of detachable without stub bar core rod mould, detachable is will along planned course, cut without hoop place under stub bar plug by wire cutting technology without stub bar rod mould, be separated into two parts, then by alignment pin, with bolt, two separated parts are being combined, realize detachablely without stub bar core rod mould, solve and be difficult at present cleaning problem.

The present invention is achieved by the following technical solutions:

Along confined planes, cut downwards, the degree of depth is 1/2 of bolt III length, and then the spacing position of reference is according to zigzag cutting track, and lateral length is advisable for surpassing alignment pin 110～15mm, and then cutting is downwards until be divided into two parts by plug; Use wire cutting technology to cut, after cutting, plug is resolved into plug I, plug II two parts, in the plane after cutting, correspondence arranges alignment pin, countersunk head screwed hole, locating hole and screwed hole.

For sebific duct processing detachable without stub bar core rod mould as a Fig. 2, it is comprised of plug I, plug II and bolt III, is provided with alignment pin 1, countersunk head screwed hole 2, locating hole 3 and screwed hole 4 between plug I and plug II; By the alignment pin of plug I and plug II 1 and locating hole 3 assemblings, then bolt III is packed in countersunk head screwed hole 2 and screwed hole 4 and fixed, complete the detachable technical scheme without stub bar core rod mould.

Effect of the present invention: as Fig. 1 is used for a long time without stub bar plug, easily produce defective material in plug iron hoop inner side, under plug, hoop is owing to can not departing from plug, so be difficult to cleaning.By the present invention, as Fig. 2 can disassemble hoop under plug smoothly in cleaning defective material by plug, make lower hoop depart from plug, reach the object of easy cleaning.

Fig. 3: with reference to spacing Position Design zigzag cutting track schematic diagram.

The specific embodiment

Below in conjunction with marginal data the specific embodiment of the present invention.

The present invention is a kind of detachable without stub bar plug.

Design, the embodiment of design cutting track:

As Fig. 3, with reference to spacing Position Design zigzag cutting track, (track requires as to cut downwards along confined planes, length is 1/2 of bolt III length, then cutting left, length is advisable for surpassing alignment pin 110～15mm, then cutting is downwards until be divided into two parts by plug), use wire cutting technology to cut, after cutting, plug is resolved into plug I, plug II two parts, requirement according on chat cutting track, as carried out the processing of alignment pin 1, countersunk head screwed hole 2, locating hole 3, screwed hole 4 in the plane of Fig. 2 after cutting.

The detachable preparation method without stub bar core rod mould that the present invention processes for sebific duct: as Fig. 2 processes 1, one countersunk head screwed hole 2 of an alignment pin on plug I.In plug II, process 3, one screwed holes 4 of a locating hole.During assembling, the alignment pin of plug I and plug II 1 and locating hole 3 are assembled, then bolt III is packed in countersunk head screwed hole 2 and screwed hole 4 and fixed, complete the detachable assembling without stub bar core rod mould.

As Fig. 1, without stub bar core rod mould, be monolithic construction in the past, lower hoop cannot depart from plug, and in long-time use, lower hoop inwall easily produces defective material, and cannot clear up.As the present invention, will be designed to Demountable without stub bar core rod mould, by disassembling of plug, can make lower hoop depart from plug, clear up, after combination, become complete plug, can put into production.

As shown in Figure 2, during dismounting, bolt III is backed out, plug I and plug II are slowly pulled down and can complete the detachable detachable technical scheme without stub bar core rod mould of having disassembled without stub bar core rod mould along alignment pin.

Structure of the present invention is without any pro forma restriction, allly according to example of the present invention, does any simple modification and modification, within all belonging to technical scheme scope of the present invention.

Claims

One kind detachable without stub bar core rod mould, it is characterized in that cutting downwards along confined planes, the degree of depth is 1/2 of bolt length, and then the spacing position of reference is according to zigzag cutting track, lateral length is for surpassing alignment pin 110～15mm, and then cutting is downwards until be divided into two parts by plug; Use wire cutting technology to cut, after cutting, plug is resolved into plug I, plug II two parts, in the plane after cutting, correspondence arranges alignment pin, countersunk head screwed hole, locating hole and screwed hole.
