Description
Technical field
The utility model relates to a kind of moulds, and the mould being molded to double-colored product can be completed by particularly relating to one kind
Tool.
Background technique
It is well known that injection mold is a kind of tool for producing plasthetics；Also be to confer to plasthetics complete structure and
The tool of accurate dimension.Injection molding is a kind of processing method used when producing certain complex-shaped components in batches.It refers specifically to
The plastics of heated thawing are injected into die cavity by injection molding machine high pressure and obtain formed products after cooling and solidifying.
But traditional injection mold is merely able to support a kind of production method of material single injection-molded, and current production
Product are mostly made of two or more materials, and traditional production method is all to make multiple components respectively, then pass through the side of gluing
Formula obtains finished product, but its overall structure stability of this finished product is poor, and complex manufacturing technology, and this is the master for traditional technology
Want disadvantage.
Utility model content
The technology employed by the present utility model is a kind of bicolor injection mould comprising the first injecting head, the second note
Head and molding mode are moulded, first injecting head and second injecting head are arranged at the top of the molding mode simultaneously, the molding
The first forming cavity and the second forming cavity are offered on mode top surface, which is provided with first runner, this
One runner is connected with first forming cavity, which is provided with second flow channel, the second flow channel and this second
Forming cavity is connected.
The bicolor injection mould further includes rotating unit, which is arranged at the top of the rotating unit, the rotation list
Member can drive the molding mode to rotate, which includes fixed station, shaft, transmission gear and driving gear, wherein
The fixed station is fixedly connected on the molding mode bottom surface, is fixedly connected on the fixed station at the top of the shaft, the shaft bottom
It is screwed in the transmission gear, which is meshed with the driving gear, and when specific implementation, which connects
It connects on the output shaft of motor.
The shaft bottom is provided with external screw thread, corresponding with the external screw thread, offers spiral shell in the transmission gear central location
Pit is provided with internal screw thread in the threaded hole, and the external thread spiro fastening is in the threaded hole.
When work, which drives the driving gear to rotate, which drives the transmission gear to rotate, when this
When transmission gear rotates, firstly, screw togather relationship by between the external screw thread and the threaded hole, make the shaft drive this at
Pattern benevolence is rotated and is moved down, when the external screw thread moves to the external screw thread extreme limit of travel, the shaft and the driving cog wheel lock
Extremely, so make the transmission gear by the shaft drive the molding mode rotate, with change the first injecting head, the second injecting head with
Relative position between first forming cavity and the second forming cavity.
The utility model has the following beneficial effects: first injecting head is docked to first when utility model works
In the first runner, then material is molded by first injecting head and finished product first is formed and formed in first forming cavity
Point, then, which is docked in the first runner by molding mode rotation, is infused material by second injecting head
It moulds and is formed in first forming cavity and form finished product second part, at the same time, which is docked to the second
In road, material is molded by first injecting head to be formed in second forming cavity and forms finished product first part, is so recycled past
It is multiple, the injection molding by several times to finished product first part and second part is completed, and combine first part with second part
Finished product is formed, first part has different colors from second part in practice, and to realize double-shot moulding, the utility model has
The characteristics of high degree of automation, high production efficiency.
Detailed description of the invention
Fig. 1 is the schematic perspective view of the utility model.
Fig. 2 is the dimensional decomposition structure diagram of the utility model.
Fig. 3 is the structural schematic diagram of the utility model rotating unit.
Specific embodiment
As shown in Figure 1-3, a kind of bicolor injection mould comprising the first injecting head 10, the second injecting head 20 and molding
Mode 30.
First injecting head 10 and second injecting head 20 are arranged simultaneously at 30 top of molding mode.
The first forming cavity 40 and the second forming cavity 50 are offered on 30 top surface of molding mode.
First forming cavity, 40 side is provided with first runner 41, which is connected with first forming cavity 40
It is logical.
Second forming cavity, 50 side is provided with second flow channel 51, which is connected with second forming cavity 50
It is logical.
When utility model works, first injecting head 10 is docked in the first runner 41 first, then object
Material is molded by first injecting head 10 to be formed in first forming cavity 40 and forms finished product part A.
Then, which is docked in the first runner 41 by the molding mode 30 rotation, by second note
Material is molded by modeling head 20 to be formed in first forming cavity 40 and forms finished product part B.
At the same time, which is docked in the second flow channel 51, and material is molded by first injecting head 10
Finished product part A is formed and formed into second forming cavity 50, is looped back and forth like this, and is completed by several times to finished product part A and the portion B
The injection molding divided, and part A and part B is made to be grouped together into finished product, part A has different colors from part B in practice,
To realize double-shot moulding, the utility model has the characteristics of high degree of automation, high production efficiency.
The bicolor injection mould further includes rotating unit 60, and the molding mode 30 setting, should at 60 top of rotating unit
Rotating unit 60 can drive the molding mode 30 to rotate.
