Abstract
The utility model relates to a kind of open-core type single port mold insert structures, bottleneck for clamped bottle forms, 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 fixation hole, cavity is equipped in the mold core, cavity is communicated with fixation hole, and cavity is located at the position of center line of mold core.For the utility model due to being provided with cavity, so that the straight line portion of mold core becomes hollow-type structure, hollow-type structure plays certain insulation effect, improves the temperature of mold core at work, so as to avoid there is fried mouth phenomenon, ensure that product quality.
Description
Technical field
The utility model relates to a kind of open-core type single port mold insert structure, the bottleneck for clamped bottle is formed.
Background technique
Borosilicate glass sleeve for pen type syringe is commonly called as clamped bottle, is applied to the neck such as genetic engineering, bioengineering, insulin
Domain.The syringe of the similar not push rod of clamped bottle, is equivalent to " bottle for not having bottom ".This bottle of front 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, use process medical fluid is not contacted with syringe any part.
Clamped bottle in the production process, is needed using to open-core type single port mold insert structure, existing open-core type single port mold core
Structure head straight line portion be it is solid, fuse and drop time of contact are short, and fuse temperature is low to be easy to appear fried mouth, especially exist
It is especially prominent in the case that machine speed is slow.
Utility model content
According to the above-mentioned deficiencies in the prior art, being solved technical problem to be solved by the utility model is: providing one kind
The above problem, core temperature is improved, the open-core type single port mold insert structure for fried mouth phenomenon occur is avoided.
The technical scheme adopted by the utility model to solve the technical problem is as follows: open-core type single port mold insert structure includes one
The mold core seat of formula structure and the mold core at mold core seat top center, the bottom of mold core seat is equipped with fixation hole, described
Cavity is equipped in mold core, cavity is communicated with fixation hole, and cavity is located at the position of center line of mold core.
The cavity is circular cylindrical cavity, and the diameter of cavity is 4mm smaller than the diameter of mold core.Heat insulation effect is more preferable.
Use principle are as follows:
Due to being provided with cavity, so that the straight line portion of mold core becomes hollow-type structure, hollow-type structure plays one
Fixed insulation effect improves the temperature of mold core at work, so as to avoid there is fried mouth phenomenon, ensure that product quality.
Beneficial effect possessed by the utility model is: the utility model is due to being provided with cavity, so that the straight line of mold core
Part becomes hollow-type structure, and hollow-type structure plays certain insulation effect, improves the temperature of mold core at work,
So as to avoid there is fried mouth phenomenon, product quality ensure that.
Detailed description of the invention
Fig. 1 is the structural schematic diagram of the utility model.
In figure: 1, mold core seat；2, mold core；3, fixation hole；4, cavity.
Specific embodiment
The embodiments of the present invention are described further with reference to the accompanying drawing:
As shown in Figure 1, open-core type single port mold insert structure includes the mold core seat 1 of integral structure and is located at the top of mold core seat 1
The mold core 2 of center position, the bottom of mold core seat 1 are equipped with fixation hole 3, are equipped with cavity 4 in the mold core 2, cavity 4 and fixed
Hole 3 communicates, and cavity 4 is located at the position of center line of mold core 2.
Cavity 4 is circular cylindrical cavity, and the diameter of cavity 4 is 4mm smaller than the diameter of mold core 2.
Use principle are as follows:
Due to being provided with cavity 4, so that the straight line portion of mold core 2 becomes hollow-type structure, hollow-type structure is played
Certain insulation effect improves the temperature of mold core 2 at work, so as to avoid there is fried mouth phenomenon, ensure that product matter
Amount.
