Description
Technical field
The utility model relates to mould, particularly relates to a kind of complete pre-embedding needle cylinder mould of hot flow path.
Background technology
Syringe for human injection worldwide successively experienced by four generation product:
(1) nonexpondable all-glass syringe;
(2) disposable aseptic plastic syringe;
(3) disposable pre-encapsulated injector;
(4) nitrogen high pressure needleless injector.
At present, the less use of first generation all-glass syringe.The disposable aseptic plastic syringe of the second generation generally uses in the whole world, although it is low to have cost, advantage easy to use, himself is defectiveness also, as not acid and alkali-resistance, reclaims use, contaminated environment etc.Therefore, developed countries and regions progressively promotes the use of the pre-encapsulated injector of the third generation.Forth generation product is also in the development stage.
Pre-encapsulated injector is widely used at European & American Market, and in China, its superiority has also obtained the generally accreditation of pharmacy corporation and consumer, but market capacity only has several ten million.Wherein the high price of syringe is undoubtedly one of principal element of its application of restricting current.
The syringe of pre-encapsulated injector mainly uses glass material at present, in transport, use procedure, there is very easily cracked problem.COP(optical material newly developed in industry) plastics pre-embedding syringe while avoiding cracked problem, keep high transparent, the stability (low-protein adsorptivity) of good wet sterilization and good chemistry.
Same as a kind of new material, COP due to its mobility poor, still do not use the mould of the pre-embedding syringe of full hot runner molding COP both at home and abroad.The such as industry-leading person such as domestic Wei Gao group and the only smart machine of Japan, when the pre-embedding syringe of trial COP, mainly remains and uses cold runner injection mo(u)lding.During the pre-embedding syringe of the shaping COP of cold runner die, mainly there is following problem points:
1) for medical product, cold runner gate waste cannot reclaim and reuse, and causes COP syringe product sizing material high cost;
2) cold runner die, in injection molding process, needs cool cold runner the extra cool time of more than 2 seconds, causes injection cycle long, production high cost;
3) cold runner die is in injection molding process, due to injection pressure and wavefront temperature losses excessive, the 8 above multi-cave moulds in cave cannot be realized, cause production efficiency low.

As further improvement of the utility model, described front mould is provided with sprue gate, and described first hot flow path exothermic sleeve is arranged in described sprue gate.
The beneficial effects of the utility model are: pass through such scheme, enter the full hot flow path of glue by the first hot flow path exothermic sleeve, the second hot flow path exothermic sleeve heated side, the sizing material that side is entered in the full hot flow path of glue keeps molten condition in process of production, and sizing material can not cool and freeze, the mobility of sizing material can be kept, be conducive to carrying out the production of many caves, enhance productivity, and, do not need extra cool time, production cycle is shorter, can save cold runner sizing material cost, is lowered into and generates this.
Accompanying drawing explanation
Fig. 1 is the structural representation of the pre-embedding needle cylinder mould of a kind of full hot flow path of the utility model.
Detailed description of the invention
To illustrate below in conjunction with accompanying drawing and detailed description of the invention further illustrates the utility model.
Drawing reference numeral in Fig. 1 is: the full hot flow path 1 of glue is entered in side; Front mould 2; Front mould mold insert 3; Product 4; Rear mold mold insert 5; First hot flow path exothermic sleeve 11; Second hot flow path exothermic sleeve 12; Glue sprue mold insert 13 is entered in side.
As shown in Figure 1, a kind of complete pre-embedding needle cylinder mould of hot flow path, comprise front mould 2 and rear mold, described front mould 2 is provided with side and enters the full hot flow path 1 of glue, described front mould 2 is provided with the first hot flow path exothermic sleeve 11 and the second hot flow path exothermic sleeve 12, described first hot flow path exothermic sleeve 11, second hot flow path exothermic sleeve 12 is coaxially arranged, and described side is entered the full hot flow path of glue 1 and is set in respectively in described first hot flow path exothermic sleeve 11, second hot flow path exothermic sleeve 12.
The product 4 of a kind of full hot flow path pre-embedding needle cylinder mould that the utility model provides is described for the pre-embedding syringe of COP.
As shown in Figure 1, described side is entered the full hot flow path 1 of glue and is connected with side and enters glue sprue mold insert 13.
As shown in Figure 1, described side is entered the full hot flow path 1 of glue and is connected with at least two sides and enters glue sprue mold insert 13.
As shown in Figure 1, the full hot flow path of glue 1 is entered in described side is one go out four sides and enter the full hot flow path of glue.
As shown in Figure 1, described one goes out the single-point side gate entering the full hot flow path of glue in four sides is directly overlapped on the pre-embedding syringe of COP, described one go out four sides enter the full hot flow path of glue 4 be 90 degree uniform.
As shown in Figure 1, described front mould 2 is provided with front mould mold insert 3, and described rear mold is provided with rear mold mold insert 5, and front mould mold insert 3, rear mold mold insert 5 enclose the die cavity of product 4.
As shown in Figure 1, the top that the full hot flow path 1 of glue is entered in described side is provided with top contraction portion.
As shown in Figure 1, described first hot flow path exothermic sleeve 11 both ends open, described second hot flow path exothermic sleeve 12 one end open, the other end are closed.
As shown in Figure 1, the pre-embedding needle cylinder mould of described full hot flow path does not arrange cold runner.
As shown in Figure 1, described front mould 2 is provided with sprue gate, and described first hot flow path exothermic sleeve 11 is arranged in described sprue gate.
As shown in Figure 1, the pre-embedding needle cylinder mould of the full hot flow path of the one that the utility model provides, by heating and the precise temperature control effect of described first hot flow path exothermic sleeve 11, second hot flow path exothermic sleeve 12, the COP sizing material that described side is entered in the full hot flow path 1 of glue keeps molten condition in process of production, under injection pressure effect, enter glue sprue mold insert 13 by side during injection, directly enter the shaping COP syringe of mold cavity.When injection terminates to cancel injection pressure, COP sizing material is still in side and enters glue sprue mold insert 13 sharp-tongued place's maintenance molten condition, continues shaping at next injection cycle.Compare traditional cold runner mold, the full hot flow path of the one that the utility model provides pre-embedding needle cylinder mould is in whole injection moulding process, the hot flow path connected between injection machine nozzle and mold cavity cast gate keeps molten condition always, there will not be in cold runner die forming process, because cold runner cooling is freezed, need the shaping cold runner of extra sizing material.
The pre-embedding needle cylinder mould of the full hot flow path of the one that the utility model provides has the following advantages:
1, there is no cold runner, save the cold runner sizing material cost of production process.
2, compare cold runner die, avoid the extra cold runner cooling cycle at injection molding cycle, shorten life cycle of the product.
3, owing to using full hot flow path, avoid in cold runner injection molding process, injection pressure and the excessive problem of wavefront temperature losses, for the making of the multi-cave mould realizing more than 8 caves provides possibility.
Above content is in conjunction with concrete preferred embodiment further detailed description of the utility model, can not assert that concrete enforcement of the present utility model is confined to these explanations.For the utility model person of an ordinary skill in the technical field, without departing from the concept of the premise utility, some simple deduction or replace can also be made, all should be considered as belonging to protection domain of the present utility model.
