Abstract
The utility model discloses a kind of thermoplasticity PET many specifications injection moulding bottle base core bar, it comprises the three cover injection moulding core bars that external diameter is respectively 17mm, 18mm and 19mm, and be wherein equipped with cooling water pipe in each injection moulding core bar, the bottom opening of this cooling water pipe is multiple tooth structure.The utility model, by the increase of core bar external diameter, can make bottle base reduce PET materials and reach about 15%; The design optimization of cooling water pipe head can improve the internal stress quality problems bottom bottle base, thus makes to be beneficial to the effect that stretching reaches the rate of reducing the number of rejects and seconds in bottle blowing process.
Description
Technical field
The utility model belongs to injection mold field, is specifically related to a kind of thermoplasticity PET many specifications injection moulding bottle base core bar.
Background technology
Vertical injection molding machine injection mold mainly comprises: the parts such as lip mould, injection moulding die cavity, assembly, injection moulding core bar, cooling water pipe, top board, lower platen, ejecting device, hot flow path.A set of vertical injection molding machine injection mould processing cost is higher, and current PET bottle base subtracts this energy-saving low-carbon bottle of grammes per square metre bottle lightweight processing trend, traditionally processes that a set of to subtract grammes per square metre injection mold cost higher.
Avoid the problems referred to above, just must improve the preparation method that vertical injection molding machine subtracts grammes per square metre injection mold, that reduces mold component repeats processing, is optimized design again processes the object reaching and subtract grammes per square metre to section components, thus reduces manufacturing cost.
Summary of the invention
The purpose of this utility model redesigns preform mould, by regulating core bar size, carries out the preparation of blowing same bottle-type Different Weight bottle base, adapts to bottle base and subtract this energy-saving low-carbon bottle of grammes per square metre bottle lightweight processing trend.
The technical solution of the utility model is: a kind of thermoplasticity PET many specifications injection moulding bottle base core bar, it comprises the three cover injection moulding core bars that external diameter is respectively 17mm, 18mm and 19mm, wherein be equipped with cooling water pipe in each injection moulding core bar, the bottom opening of this cooling water pipe is multiple tooth structure.
Further, the bottom opening of the cooling water pipe of injection moulding core bar inside is multiple tooth lace shape structure.
The utility model reaches by replacing existing mold being carried out to key components and parts the weight decreasing bottle base, decreases the consumption of raw material simultaneously, improves yield rate, reduces manufacturing cost.It is 18mm and 19mm injection moulding core bar that the utility model moulds increase by two cover external diameters on the basis of core bar external diameter 17mm in reservation original annotation, by changing tack bottom core bar inner cooling water pipe into multiple tooth lace shape, reaching bottle base and subtracting grammes per square metre and the shaping good object of bottle base.
The beneficial effects of the utility model:
1, by the increase of core bar external diameter, bottle base can be made to reduce PET materials and to reach about 15%;
2, the core bar processing by increasing subtracts grammes per square metre Mould Machining and can save medicine cost more than 50%;
3, the design optimization of cooling water pipe head can improve the internal stress quality problems bottom bottle base, thus makes to be beneficial to the effect that stretching reaches the rate of reducing the number of rejects and seconds in bottle blowing process.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Fig. 2 is the polycrystalline substance upward view of the cooling water pipe of injection moulding core bar inside.
Fig. 3 is the injection moulding core bar of original outside diameter 17mm.
In figure, 1-injection moulding core bar, 2-cooling water pipe, at the bottom of the cooling water pipe of the multiple tooth lace shape structure of 3-, at the bottom of 4-tack cooling water pipe.
Detailed description of the invention
Below in conjunction with drawings and Examples, the utility model is further described.
As shown in Figure 1, thermoplasticity PET many specifications injection moulding bottle base core bar of the present utility model comprises three cover injection moulding core bars 1, is respectively 17mm, 18mm and 19mm from a left side from its external diameter right.In each injection moulding core bar 1, be equipped with cooling water pipe 2, the bottom opening of this cooling water pipe 2 is multiple tooth lace shape structure.The mouth of pipe wall that described multiple tooth lace shape structure refers to cooling water pipe has circumferentially been covered with some teeth, and the crown of each tooth and tooth root length can be consistent along the mouth of pipe wall of nozzle diameter direction and cooling water pipe.The upward view of the multiple tooth lace shape structure at the bottom of this cooling water pipe a kind of as shown in Figure 2.
Many specifications injection moulding bottle base core bar of the present utility model adopts the scheme that external diameter increases and cooling water pipe head is optimized, as compared to only adopting at the bottom of 17mm external diameter core bar and tack cooling water pipe in Fig. 3, bottle base can be made when injection moulding to reduce PET materials and reach about 15% and the percent defective that obviously can reduce bottle blowing process.
