Description

A kind of blow molding stock mould of plastic bottle

Technical field

The utility model relates to a kind of blow molding stock mould in plastic bottle producing industry, and in particular to arrives a kind of plastics The blow molding stock mould of bottle.

Background technique

Currently, the blow molding stock mould of traditional plastic bottle, structure includes: a pair of openable and closable blow molding sizing half module, is blown The bottle body type chamber being connected and bottleneck type chamber are offered in modeling sizing half module.This structure blow molding stock mould corresponds to a kind of bottle The bottle material bottle of mouthful screw thread, moreover, being limited by bottle body type chamber, bottle mouth position can only open up the lesser cooling hole of flow, cannot open up with The cooling chamber that bottleneck is harmonious cannot be sufficiently cool bottleneck, so that the molding time of bottleneck is longer.

Utility model content

Various whorl of bottleneck are suitable for the technical problem to be solved by the utility model is to provide one kind and can be to bottleneck The blow molding stock mould for the plastic bottle being fully cooled.

In order to solve the above technical problems, the technical solution adopted by the utility model is: a kind of blow molding stock mould of plastic bottle, Its structure includes: a pair of openable and closable blow molding sizing half module, offers the bottle matched with bottle body type chamber in blow molding sizing half module Body cooling chamber, blow molding sizing half module offer the big stairstepping in inboard small outside at position corresponding with the bottleneck of plastic bottle upwards Bottleneck mold insert gap is installed, the two sides of the bottom of bottleneck mold insert installation gap offer communicates with the bottle body cooling chamber respectively Bottleneck cooling hole, bottleneck mold insert installation gap in be disposed with bottleneck Hough mold insert and mold insert pressing plate, mold insert outside by inner Pressing plate is fixed on blow molding sizing half module, is offered respectively on the both sides of the face of bottleneck Hough mold insert inner end cold with corresponding bottleneck But the bottleneck cooling chamber that hole communicates, bottleneck Hough mold insert offer the seal groove of closed loop, seal groove on the periphery of bottleneck cooling chamber In be provided with sealing ring.

As a preferred embodiment, in a kind of blow molding stock mould of plastic bottle, the bottleneck cooling chamber T-shaped barrier block has been centrally located on the bottom wall of outside.

As a preferred embodiment, in a kind of blow molding stock mould of plastic bottle, the peace of the mold insert briquetting Dress mode are as follows: offer at least one respectively on the two sides step of bottleneck mold insert installation gap and threaded hole, the edge is fixedly mounted The two sides of part pressing plate offer the fixed installation through-hole matched with the fixing screwed hole of corresponding side respectively, and fixed-use bolt is worn Cross corresponding fixed installation screw thread of the fixed hole tightening on mold insert pressing plate on bottleneck mold insert installation gap corresponding side step Kong Zhong.

The beneficial effects of the utility model are: the utility model is by the way that position corresponding with the bottleneck of plastic bottle to be arranged At bottleneck mold insert, to only need to change bottleneck mold insert when preparing the plastic bottle of different bottle mouth screw thread；Furthermore, it is possible in bottle The bottleneck cooling chamber matched with bottleneck is opened up on mouth mold insert, which adds the cooling effects to bottleneck, so as to contract Short cooling time, production efficiency is improved by a relatively large margin.

Detailed description of the invention

Fig. 1 is the structural schematic diagram of the blow molding stock mould of plastic bottle described in the utility model.

Fig. 2 is the enlarged structure schematic diagram of bottleneck Hough mold insert in Fig. 1.

Fig. 3 is the present invention looks up structural representation of Fig. 2.

Appended drawing reference of the Fig. 1 into Fig. 3 are as follows: 1, blow molding sizing half module, 11, bottle body type chamber, 2, bottleneck Hough mold insert, 20, Bottleneck cooling chamber, 201, T-shaped barrier block, 21, whorl of bottleneck, 22, sealing ring, 3, mold insert pressing plate, 4, fixed-use bolt.

Specific embodiment

Below with reference to Fig. 1 to Fig. 3, one kind described in the utility model is described in detail so that one goes out two blow molding stock mould as an example The specific embodiment of the blow molding stock mould of plastic bottle.

As shown in Figure 1, the blow molding stock mould of plastic bottle described in the utility model, comprising: a pair of openable and closable blow molding is fixed Type half module 1 offers the bottle body cooling chamber matched with bottle body type chamber 11 and (belongs to the usual of this field in blow molding sizing half module 1 Technology is not shown in the figure), blow molding sizing half module 1 offers inboard small outside at position corresponding with the bottleneck of plastic bottle upwards Big step-like bottleneck mold insert installs gap, and the two sides of the bottom of bottleneck mold insert installation gap offer and the bottle body respectively The bottleneck cooling hole (belonging to the conventional techniques of this field, be not shown in the figure) that cooling chamber communicates, the bottleneck mold insert installation are slitted It is disposed with bottleneck Hough mold insert 2 and mold insert pressing plate 3 in mouthful outside by inner, mold insert pressing plate 3 is fixed on blow molding sizing half module 1 On, the specific mounting means of mold insert pressing plate 3 are as follows: offer at least one respectively on the two sides step of the bottleneck mold insert installation gap A fixed installation threaded hole (it is usually two that threaded hole, which is fixedly mounted, quantity can according to the actual situation depending on), the mold insert The two sides of pressing plate 3 offer the fixed installation through-hole matched with the fixing screwed hole of corresponding side respectively, and fixed-use bolt 4 is worn Cross corresponding fixed installation screw thread of the fixed hole tightening on mold insert pressing plate 3 on bottleneck mold insert installation gap corresponding side step Kong Zhong；As shown in Figures 2 and 3, it is offered respectively on the both sides of the face of 2 inner end of bottleneck Hough mold insert cold with corresponding bottleneck But the bottleneck cooling chamber 20 that hole communicates, bottleneck Hough mold insert 2 offers the seal groove of closed loop on the periphery of bottleneck cooling chamber 20, close Sealing ring 22 is provided in sealing groove；In order to increase cooling effect, it is centrally located on the outside bottom wall of the bottleneck cooling chamber 20 There is T-shaped barrier block 201, the top of T-shaped barrier block 201 is arranged to the cambered surface matched with bottleneck.

The utility model (is breathed out by the way that position corresponding with the bottleneck of plastic bottle is arranged to bottleneck mold insert by a pair of of bottleneck Husband's mold insert 2 forms), to only need to change bottleneck mold insert when preparing the plastic bottle of different bottle mouth screw thread；Furthermore, it is possible to The bottleneck cooling chamber 20 matched with bottleneck is opened up respectively on a pair of of bottleneck Hough mold insert 2, and which adds to the cold of bottleneck But effect improves production efficiency so as to shorten cooling time by a relatively large margin.

In conclusion the preferred embodiment of only the utility model, is not used to limit the utility model implementation Range, it is all according to equivalent change made by shape described in the utility model claims range, construction, feature and spirit with repair Decorations, should all include in the scope of the claims of the utility model.
