To achieve the above object, a kind of needle base lid injection mold provided by the utility model comprising from top to bottom
Top plate, cope plate, lower template, push plate, stripper plate, backing plate and the bottom plate being set in sequence；The cope plate and the lower template
Opposite face setting be formed with die cavity chamber, the intracavitary stream for being provided with several die cavitys and several die cavitys of connection of the die cavity
Road, the die cavity include several die cavity units；The die cavity unit includes the first die cavity, the second die cavity, third die cavity and the
Four die cavitys and the runner is connected in X-type, be connected with along two adjacent die cavity units that the cope plate is axially arranged
The runner forms big die cavity unit, and axially adjacent two big die cavity unit is externally connected with the runner to mold certainly respectively
Total runner mouth.
In above-mentioned needle base lid injection mold comprising be evenly distributed in four big die cavitys in intracavitary four corner of the die cavity
The runner of unit, four big die cavity units is connected to total runner mouth of mold.
In above-mentioned needle base lid injection mold, discharging spring is provided between the stripper plate and the backing plate.
In above-mentioned needle base lid injection mold, the quantity of the discharging spring is 4, and is distributed in the four of the stripper plate
A corner.
A kind of needle base lid injection mold provided by above-mentioned technical proposal, compared with prior art, its advantages packet
It includes: the die cavity connected by the runner being arranged in X-type, the flowing for enabling mold more uniform when into glue, so that often
A die cavity unit can have preferably into glue balance, and by being connected between runner, realize between each big die cavity unit
Into glue balance, improve depanning rate.
Detailed description of the invention
Fig. 1 is one of the structural schematic diagram of the needle base lid injection mold of the utility model；
Fig. 2 is the second structural representation of the needle base lid injection mold of the utility model.
Wherein, 1- cope plate, 2- lower template, 3- die cavity unit, the big die cavity unit of 4-, 5- runner, 6- discharging spring.
Specific embodiment
With reference to the accompanying drawings and examples, specific embodiment of the present utility model is described in further detail.Below
Embodiment is not intended to limit the scope of the present invention for illustrating the utility model.
Please refer to attached drawing 1-2, a kind of needle base lid injection mold provided by the utility model comprising from top to bottom according to
Top plate, cope plate 1, lower template 2, push plate, stripper plate, backing plate and the bottom plate of sequence setting；The cope plate and the lower template
Opposite face setting be formed with die cavity chamber, the intracavitary runner for being provided with several die cavitys and several die cavitys of connection of the die cavity
5, the die cavity includes several die cavity units 3；The die cavity unit 3 includes the first die cavity, the second die cavity, third die cavity and the
Four die cavitys and the runner 5 is connected in X-type, connect along two adjacent die cavity units 3 that the cope plate is axially arranged
There is the runner 5 to form big die cavity unit 4, axially adjacent two big die cavity unit 4 respectively from be externally connected with the runner 5 to
Total runner mouth of mold.
Based on above-mentioned technical characteristic, the die cavity connected by the runner 5 being arranged in X-type, so that mold is into glue
When can be more uniform flowing, each die cavity unit 3 is had preferably into glue balance, and pass through the runner
Between be connected to, realize balancing between each big die cavity unit 4 into glue, improve depanning rate.
It includes the four big die cavity unit 4 for being evenly distributed in intracavitary four corner of the die cavity, four big die cavity lists
The runner 5 of member 4 is connected to total runner mouth of mold, makes it have four big die cavity unit 4, improves depanning quantity, contracting
Short production cycle.
It is provided with discharging spring 6 between the stripper plate and the backing plate, by the way that the discharging spring 6 is arranged, improves mould
Has stability when discharging.
The quantity of the discharging spring 6 is 4, and is distributed in four corners of the stripper plate, further increases mold
Stability.
