Abstract
The utility model is related to a kind of cassette bottleneck formation die cores, mold core seat including integral structure and the mold core at mold core seat top center, the bottom of mold core seat is equipped with mounting hole, the top surface of the mold core seat is conical surface type structure, the bottom periphery of mold core is extended at the top of conical surface type structure, the bottom of conical surface type structure extends to the outer wall on mold core seat top.The utility model employs the mold core seat that top surface is conical surface type structure, in the bottleneck for making clamped bottle so that the contact area of bottleneck and mold core seat greatly reduces, and the bottleneck molded is highly polished, and size is more accurate.
Description
Technical field
The utility model is related to a kind of cassette bottleneck formation die cores, are molded for the bottleneck of clamped bottle.
Background technology
Borosilicate glass sleeve for pen type syringe is commonly called as clamped bottle, applied to necks such as genetic engineering, bioengineering, insulin
Domain.The similar syringe without push rod of clamped bottle, is equivalent to " bottle for not having bottom ".This bottle of forepart is equipped with the note of rubber seal protection
It penetrates and uses syringe needle, bottleneck is sealed with rubber plug aluminium lid, and tail portion is sealed with rubber piston.The cassette injection holder that clamped bottle merging is reused
Or used in injection pen, it is not contacted using process liquid with syringe any part.
When in use, the contact surface with bottleneck is plane to traditional clamped bottle mold core seat, and contact area is larger, causes to make
Bottleneck might have tongue and groove, influence appearance and accuracy of gauge.
Utility model content
According to the above-mentioned deficiencies in the prior art, the technical problems to be solved in the utility model is：One kind is provided to solve
The above problem, reduce the contact area of bottleneck and mold core seat, make that the bottleneck molded is highly polished, and size is more accurately blocked
Formula bottleneck formation die core.
Technical solution is used by the utility model solves its technical problem：Cassette bottleneck formation die core includes integral type
The mold core seat of structure and the mold core at mold core seat top center, the bottom of mold core seat are equipped with mounting hole, the mould
The top surface of core print seat is conical surface type structure, and the bottom periphery of mold core, the bottom of conical surface type structure are extended at the top of conical surface type structure
Extend to the outer wall on mold core seat top.
The taper of the conical surface type structure of the mold core seat top surface be 10-30 degree, preferably 20 degree.
Use principle is：
Mold core seat is fixed by mounting hole, in the bottleneck for making clamped bottle, since the top surface of mold core seat is conical surface type knot
Structure so that the contact area of bottleneck and mold core seat greatly reduces, and the bottleneck molded is highly polished, and size is more accurate.
Advantageous effect is possessed by the utility model：The utility model employs the mold core that top surface is conical surface type structure
Seat, in the bottleneck for making clamped bottle so that the contact area of bottleneck and mold core seat greatly reduces, the bottleneck finish molded
Height, size are more accurate.
Description of the drawings
Fig. 1 is the structure diagram of the utility model.
In figure：1st, mold core seat；2nd, mold core；3rd, mounting hole.
Specific embodiment
The embodiment of the utility model is described further below in conjunction with the accompanying drawings：
As shown in Figure 1, cassette bottleneck formation die core includes the mold core seat 1 of integral structure and in 1 top of mold core seat
Mold core 2 at heart position, the bottom of mold core seat 1 are equipped with mounting hole 3, and the top surface of the mold core seat 1 is conical surface type structure, the conical surface
The taper of formula structure is 10-30 degree, and the bottom periphery of mold core 2, the bottom of conical surface type structure are extended at the top of conical surface type structure
Extend to the outer wall on 1 top of mold core seat.
Use principle is：
Mold core seat 1 is fixed by mounting hole 3, in the bottleneck for making clamped bottle, since the top surface of mold core seat 1 is conical surface type
Structure so that the contact area of bottleneck and mold core seat 1 greatly reduces, and the bottleneck molded is highly polished, and size is more accurate.
