Background technique
Blood sampling test tube is used widely in medical industry in existing life, in the production process of current blood sampling test tube
In, it is most of to push push rod or push plate that the plastic cement in running channel is directly released and cleared up using artificial.But blood sampling examination
The plastic material rigidity that pipe uses is weaker and sticky larger, and thus making the plastic cement in running channel, inclined to puddle is pouring in process of production
It is in road and not easily to fall off, affect the normal die sinking of mold.And there is still a need for the plastic cement in artificial removal's running channel, drops after being opened
The low production efficiency of product, extends the production cycle of product.
Utility model content
The purpose of this utility model is to provide a kind of test tube molds, examine the artificial taking-up of needs behind the scenes to solve existing mold
The problem of plastic cement in running channel.
The technical solution that the utility model solves above-mentioned technical problem is as follows:
A kind of test tube mold, the multiple groups forming cavity to be formed is fastened including upper die and lower die and upper die and lower die, and upper mold includes
Upper cores and the male template being arranged in upper cores are equipped with the running channel being connected to forming cavity between upper cores and male template, public
In template and it is located above running channel equipped with air flue, the output end inside of air flue is equipped with inverted draw cut, is equipped with mandril in inverted draw cut；Mandril includes
The sliding part that is arranged in inverted draw cut and sliding part is set close to the top of running channel side, sliding part is close to running channel side and cunning
Reset spring is equipped between slot, reset spring is set in top outer.
When the utility model injection molding finishes and mold is opened, the plastic cement in running channel is adhesive in running channel and can not take off automatically
It falls, will be reached at mandril with the gas of certain air pressure by air flue at this time, gas applies pressure to mandril, by mandril from air flue
It is interior to release a distance and eject the plastic cement in running channel, so that the plastic cement in running channel is fallen off.When mold clamping continues injection molding, pour
Melt is again filled in road, mandril is reset in inverted draw cut in the case where the pressure of melt and the elastic force of reset spring push.
Preferably, being equipped with annular seal groove on the outside of sliding part, sealing ring is equipped in annular seal groove.
The utility model passes through the sealing ring being arranged on the outside of sliding part, and gas is avoided to reveal from sliding part, reduces top
The top power of bar.
Preferably, being equipped with multiple groups runner between running channel and forming cavity, runner both ends are passed through with running channel and forming cavity respectively
It is logical.
The utility model enables melt to enter in forming cavity from multiple positions by multiple groups runner, avoid pouring less than
The case where position.
Preferably, male template is equipped with the injection orifice being connected to running channel.
Preferably, air flue includes intake section, outlet portion and the connector being arranged between intake section and outlet portion.
Preferably, intake section intersects at connector with outlet portion and is mutually communicated.
The utility model has the following beneficial effects:
The utility model passes through the cooperation of mandril and air flue being arranged in air flue, using gas push mandril and by running channel
Interior plastic cement ejection is solved plastic cement and is adhesive in and poured instead of the artificial mode for directly being released plastic cement using push rod or push plate
In road and the problem of mold is normally opened is influenced, while reducing the workload of the following process of operator, shortens production
The product manufacturing cycle, improve production efficiency.

Specific embodiment
The principles of the present invention and feature are described below in conjunction with attached drawing, example is served only for explaining that this is practical
It is novel, it is not intended to limit the scope of the utility model.
Embodiment
Referring to Fig. 1 to Fig. 3, the utility model is by 1 and of upper mold 1, the lower die being arranged in below upper mold 12 and multiple groups upper mold
Lower die 2 fastens the forming cavity 3 formed and forms, upper mold 1 include upper cores 11 and the male template 12 that the top of upper cores 11 is set,
Injection orifice 121 is equipped in male template 12, after melt is sent to injection orifice 121 by external equipment, injection orifice 121 is by melt by pouring
Road 4 and two groups of runners 10 are injected into forming cavity 3.The both ends of forming cavity 3 are connected to runner 10 respectively, and such design is convenient
Melt is injected into all corners of forming cavity 3, injecting products is prevented and forms incomplete situation.
In male template 12 and be located at the air flue 5 that L-type is equipped with above running channel 4, air flue 5 include intake section 51, outlet portion 52 with
And the connector 53 between intake section 51 and outlet portion 52 is set.Intake section 51 is separately positioned in male template 12 and close to male model
12 outside of plate, outlet portion 52 is arranged above running channel 4.Intake section 51 intersects at connector 53 with outlet portion 52 and is mutually communicated.
Air flue 5, which is located on the inside of one end of running channel 4, is equipped with inverted draw cut 6, and the diameter of inverted draw cut 6 is greater than the diameter of air flue 5.In inverted draw cut 6
Equipped with the mandril 7 for ejecting plastic cement in running channel 4, mandril 7 includes the sliding that is arranged in inverted draw cut 6 and can slide along inverted draw cut 6
Portion 71 and sliding part 71 is set close to the top 72 of 4 side of running channel, 72 bottom end of top is contacted with the plastic cement in running channel 4.
