Even, 7 both ends of drive rod are movably connected with guide rail 2.
Rack 1 is equipped with cover half 8, and cover half 8 is located at the lower end of dynamic model 3, and 8 both ends of cover half are fixedly arranged on 1 two sides of rack, and cover half 8 is set
There is cover half mode 9 compatible with dynamic model mode 4, cover half mode 9 is equipped with die cavity 10, and 10 bottom end of die cavity is equipped with and wears cover half 8
Centre hole (does not identify) in figure, and 8 lower end of cover half is equipped with the ejector pin mechanism 100 being connected with centre hole.
Ejector pin mechanism 100 includes the thimble 11 being threaded through in centre hole, and 11 one end of thimble is connected with cover half mode 9, another
End is connected with driving plate 12, and driving plate 12 is connected away from 11 one end of thimble with cylinder 13, and cylinder 13 is fixedly arranged on 1 bottom of rack.
Before injection molding, plastic material is poured into toward injection tube 5, plastic material is melted in the heating coil fever of 5 side of injection tube.
Dynamic model 3 presses down on guide rail, presses with cover half 8, and cover half mode 9 agrees with dynamic model mode 4, the interior type for forming forming plastic pieces
Chamber.After dynamic model 3 and cover half 8 press, the melt plastic cement in 6 injection injection tube 5 of injection rod by melt plastic cement injection dynamic model 3 and is determined
In the type chamber formed in mould 8, make forming plastic pieces.Herein it should be understood that being equipped with through-hole in dynamic model, through-hole connection injection
Cylinder and dynamic model mode 4, so that the melt plastic cement in injection tube 5 under the injection of injection rod 6, enters type chamber out of injection tube 5.
After melt plastic cement in injection tube 5 is injected into type chamber, plastic parts is shaped to type is intracavitary, dynamic model 3 and drive rod 7 one
With up sliding, dynamic model 3 is separated with cover half 8.The thimble 11 of ejector pin mechanism 100 up jacks up 8 mould of cover half under the driving of cylinder
Plastic parts is taken out so that plastic parts is detached from 8 die cavity 10 of cover half, completes the molding of plastic parts by the plastic parts in chamber 10.
In this embodiment, it is preferred that 3 both ends of dynamic model and 7 both ends of drive rod are equipped with range sensor 14, monitor on dynamic model

With being closer for drive rod 7；After dynamic model 3 is separated with cover half 8, injection rod 6 is off injection, and dynamic model 3 and drive rod 7
It up moves together, at this moment dynamic model 3 is constant at a distance from injection rod 6；After the melt plastic cement in injection tube 5 is finished, injection rod 6
Injection is to the bottom of injection tube 5, and at this moment drive rod 7 is nearest at a distance from dynamic model 3, and range sensor 14 will sound an alarm, and reminds
Plastic material is added toward injection tube 5 in operator.In injection tube 5 plus when plastic material, injection rod 6 is detached from injection molding cylinder 5,
Injection tube 5 is added convenient for raw material.
On the basis of mold is equipped with injection tube 5 and 6 structure of injection rod, injection rod 6 and 5 connected end of injection tube are equipped with injection
Chock plug 15.The design of injection chock plug 15 makes injection rod 6 and the connection of injection tube 5 form closed space, so that the pressure of injection rod 6
Injection pressure all acts in melt plastic cement.Further, the material of injection chock plug 15 is ceramics, in zirconium oxide, quartz
One kind, since 5 side of injection tube is equipped with heating coil, temperature is higher, the injection caused by ceramics, zirconium oxide and quartz system
Chock plug 15, high temperature resistant and higher with the adaptation of injection tube 5.
In the present embodiment, 10 quantity of die cavity of cover half mode 9 is preferably 6-12, due to the structure letter of the utility model
It is single, and small volume, in order to guarantee the quality of forming plastic cement part, 10 quantity of die cavity of cover half mode 9 is a for 6-12, both cover half 8
It is pressed once with dynamic model 3, molding plastic parts quantity is 6-12 part.When 10 quantity of die cavity is very little, high production cost, production speed
Degree is slow；When 10 quantity of die cavity is too many, the ability to bear beyond mold, the plastic parts fraction defective manufactured is high.
11 quantity of thimble of die cavity bottom end is no less than 3, in order to which molding plastic parts intact can be ejected from die cavity 10, pushes up
The quantity of needle 11 is no less than 3, so that thimble 11 is uniform to the active force of plastic parts, reduces the deformation of plastic parts.It needs herein
Annotated to be: when dynamic model 3 and cover half 8 press, the top and 10 bottom of die cavity of thimble 11 maintain an equal level thimble 11, both push up
Needle 11 blocks centre hole, so that the type chamber that dynamic model mode 4 and cover half mode 9 are formed is closed.
The both ends of dynamic model 3 are connected with driving mechanism 16 respectively with the both ends of drive rod 7, and dynamic model 3 and drive rod 7 are in guide rail 2
On sliding driven by driving mechanism 16.Driving mechanism is by motor, the composition such as screw rod and guide rod；Either by cylinder and
The composition such as guide rod.The group of above-mentioned driving mechanism becomes preferred embodiment, but driving mechanism of the invention is not limited to above-mentioned structure.
5 upper end of injection tube is equipped with loading hopper 17.Since the upper end opening of injection tube 5 is smaller, meeting during charging
There is the case where material leakage, and the problem of the setting very good solution of loading hopper 17 feed inlet material leakage.
