Abstract

The present invention relates to a method for jetting and blowing mould seats. A plurality of core moulds on both sides of a core mould seat are respectively fixed by a core mould trimming seat so that an inserting type core mould trimming seat and the core moulds can replace a sleeve plug; a plurality of jetting hole moulds of a mould jetting seat are fixed in an inserting mode; the sleeve plug can be replaced; a bottle bottom mould of a bottle mould plug can replace a cover plate. Consequently, the integral mould jetting seat, the bottle mould seat and the core mould seat do not need replacing one by one for the transformation production of large quantity, middle quantity and small quantity according to products of needed sizes and diameters; the present invention reduces mould opening cost and shortens mould replacing time.

Description

The jet-blow moulding seat of convertible die cavity number

The present invention relates to a kind of jet-blow moulding seat.

At present, general ejaculator, bottle blowing machine all penetrate the bottle embryo with the involutory single core in single mode cave, replace together with the bottle embryo and by swivel mount Rotate 180 degree with single core again, and involutory single bottle blowing mould is made bottle blowing moulding, with regard to single ejaculation, bottle blowing, can't blow machinery and make maximum ejaculation amount and fill part and to utilize penetrating, form the restricted number of single mode ejaculation, bottle blowing, when making machinery can't suitably bring into play efficient and its to change the mould of size diameter, weight product, need with the integral core die holder, penetrate die holder, the bottle die holder change one by one, operating performance is numerous and diverse, and mould replacing time is long.

In view of this, the jet-blow moulding seat that the purpose of this invention is to provide a kind of convertible die cavity number, it is can change a plug sleeve at the ejaculation casement of penetrating die holder not shoot material, should penetrate the core and the core fine setting seat of casement institute left-and-right-hand core die holder simultaneously, also tear the transducer set plug open, and change a cover plate at the bottom mould of bottle die holder, penetrate casement, bottle mold, bottom mould, core fine setting seat and core as long as therefore change, just an available die holder can be made required size diameter product.

The object of the present invention is achieved like this: a kind of convertible die cavity is counted the jet-blow moulding seat and is comprised penetrating for one and blow machine, penetrate the core seat both sides of blowing the machine centre at this and respectively be provided with several cores, blow the ejaculation casement that machine is penetrated on the die holder installing and core equal number penetrating, at the bottom of penetrating the bottle mould that blows machine, be provided with bottom mould with the core equal number, this bottom mould front side has one bottle of mold, and connect by the rotating seat of a bracing frame on the core seat, and promote the core seat with pneumatic cylinder and just doing 180 °, oppositely transposition rotation, cooperate with core again and penetrate a casement do ejaculation bottle embryo, and and bottom mould, the bottle mold is done the bottle blowing demoulding, it is characterized in that: several cores of core seat both sides are fixing with core fine setting seat respectively, make insertion type mould fine setting seat and the removable transducer set plug of core, and several ejaculation moulds of penetrating die holder are that insertion type is fixed, removable transducer set plug, and the bottle bottom mould that formpiston had can change a cover plate.

Owing to adopt such scheme: can fill a part utilization and penetrate maximum ejaculation amount and the maximum die space that blows machine, reduce the die sinking expense simultaneously and shorten mould replacing time.

The present invention is further described below in conjunction with drawings and Examples.

Figure 12 is second kind of the third state diagram of embodiment of the present invention;

Among the figure: 1. core seat 11. cores 12. core holes 13. cores fine setting seat 14. cover plugs 2. are penetrated die holder 21. nibs 22. and are penetrated 31. bottles of molds of casement 23. cover 3. bottles of die holders of plug, 32. nibs, 33. bottom moulds, 34. cover plates, 4. rotating seats, 5. pneumatic cylinder A, B, C, D, E die cavity

As shown in Figure 1, the present invention system comprises penetrating for one blows machine, penetrate core seat 1 both sides of blowing the middle place of machine at this and respectively be provided with several core holes 12, this core hole 12 is can be for core fine setting seat 13 covers solid and plug core 11 (shown in Fig. 2,3), and the core 11 of both sides correspondence is respectively penetrated die holder 2, bottle die holder 3, penetrated die holder 2 and be provided with several nibs 21 and mould 11 same quantity.Plug (as shown in Figure 4) for penetrating casement 22, penetrate blow machine the bottle die holder 3 be provided with several bottom moulds 33, and with ejaculation casement 22, core 11 equal numbers, again the bottle 33 front side devices, one left side, the end, the bottle mold 31 of right opening and closing, this bottle mold 31 offers nib 32 with bottom mould 33 equal numbers (as Fig. 5, shown in 6), wherein, core seat 1 is to be connected by a rotating seat that supports 1, promoting Rotate 180s ° just with pneumatic cylinder 5, oppositely commutation, core 11 is cooperated penetrate casement 22 do ejaculation bottle embryos, and with bottom mould 33, bottle mold 31 is done the bottle blowing demoulding, it is characterized in that:

Core seat 1, as Fig. 2, shown in 3, several cores 11 of its both sides are respectively fixing with freestanding core fine setting seat 13, make insertion type mould fine setting seat 13 and core 11, removable transducer set plug 14, and several ejaculation moulds 22 of penetrating die holder 2 (as shown in Figure 4) are that insertion type is fixed, removable transducer set plug 23, and bottle die holder 3 is (as Fig. 5, shown in 6) bottom mould 33 that had can change a cover plate 34, so that single just changeing penetrated casement 22, bottle mold 31, bottom mould 33, core fine setting seat 13 and core 11, need not integral body penetrated die holder 2, bottle die holder 3, core seat 1 changes one by one, can comply with required size diameter product, it is big to do conversion, in, small lot batch manufacture, it is short to reduce die sinking cost mould replacing time.

Required size diameter product can be complied with by first embodiment system, does large, medium and small batch process, as being example with three die cavitys, shown in Fig. 7～9.

1. single mode cave: use B mould (A, C mould clog with overlapping), as shown in Figure 7, can produce the product greater than bimodulus cave diameter or weight, the die cavity number is less, can reduce the die sinking expense, is suitable for limited production.

2. bimodulus cave: use A, C (the B mould clogs with overlapping), as shown in Figure 8, can produce product, be suitable for medium quantity batch processing greater than three die cavity diameters or weight.

3. three die cavitys: use A, B, C mould, as shown in Figure 9, be suitable for a large amount of productions.

Second embodiment is as being example with five die cavitys, shown in Figure 10～12.

1. single mode cave: use C mould (A, B, D, E mould clog with cover), as shown in figure 10, can produce the product greater than bimodulus cave diameter or weight, the die cavity number is less, can reduce the die sinking expense, suitable limited production.

2. bimodulus cave: use B, D (A, C, E mould clog with overlapping), as shown in figure 11, can produce the product greater than bimodulus cave diameter or weight, the die cavity number is less, can reduce the die sinking expense, is suitable for small lot batch manufacture.

3. five die cavitys: use A, B, C, D, E mould, as shown in figure 12, be suitable for a large amount of productions.
