Secondary molding various materials or multi-color injection molded, but still those hollow sealing mouldings for needing second of processing can not be carried out, in this way
It needs more equipment or manpower to carry out secondary operation, consumes manpower and material resources and hall space, increase cost of investment.
Summary of the invention
The technical problems to be solved by the invention: overcome the above-mentioned insufficient of the prior art and provide simple a kind of hollow
Injection molding forming method, can be certain hollow injection moulded products with sealing for needing secondary process processing；Design exists
It is executed in mold, when leaving die cavity, oneself is final finished product to the hollow plastic part of sealing.
The technical scheme adopted by the invention to solve the technical problem are as follows: a kind of hollow injection molding forming method, including movable plate,
Dynamic model, submodule driving device, submodule, fixed board, cover half and injection mechanism；It is characterized in that: dynamic model, submodule, cover half have molded
Cheng Hou, injection molding machine carry out action of injection, and to distance is needed, dynamic model passes through submodule driving device driving for die sinking after the completion of injection
Mould matches next station, then carries out mould assembling action again, originally separated different component products is stitched together, then
Biphasic injection is carried out, together by plastic-injection by separated different products, completes hollow injection moulded products.The present invention
The process of certain second of processing of needs, the hollow product with sealing of welding is especially needed；Design is held in mold
Row, band seal hollow plastic part when leaving die cavity oneself be final finished product, improve product assembly quality stability and
Cooperate compactness, saves manpower and material resources and hall space.
The submodule driving device can be driven by rotation oil motor electrical motor driven or oil cylinder driving；It needs
It wants molding hollow product to can be symmetrical or equal product, is also possible to asymmetric or unequal product, molding modeling
Glue part can be the product of different material same color, or be the product of identical material different colours, or different for different colours
The product of material, or formed for the product of the identical material of same color.
The injection mechanism can be it is same penetrate platform, can also be made of multiple platforms of penetrating.
Beneficial effects of the present invention: a kind of hollow injection molding forming method, it can be the band of certain second of processing of needs
The hollow injection moulded products of sealing, design execute in mold, and when leaving die cavity, oneself is final finished product to plastic parts, is mentioned
High product assembly quality stability and cooperation compactness, save manpower and material resources.
Detailed description of the invention

In the figure, it is marked as 1. movable plates；2. dynamic model；3. submodule；4. fixed board；5. cover half；6. injection mechanism；7. hollow product；
8. submodule driving device.
Fig. 2 is a kind of work flow schematic diagram of hollow injection molding forming method, from Fig. 2-1 to Fig. 2-5.
Specific embodiment
The present invention will be described in further detail below with reference to the embodiments of the drawings.
As shown in Figure 1, a kind of hollow injection molding forming method, including movable plate (1), dynamic model (2), submodule driving device (8), son
Mould (3), fixed board (4), cover half (5), injection mechanism (6) and product produced (7)；It is characterized in that: dynamic model (2) is mounted on
On movable plate (1), cover half (5) is mounted on fixed board (4), dynamic model (2), submodule (3), after the completion of cover half (5) molding, injection molding machine injection
Mechanism (6) carries out action of injection for the first time, and two stations inject product into two respectively in mold, is then opened, dynamic model (2) passes through
Submodule driving device (8) drives submodule (3) to match next station, and then injection molding machine carries out mould assembling action again, will separate originally
Different component products be stitched together, then injection mechanism of injection machine (6) carry out biphasic injection movement, by separated hollow system
Product together, complete the hollow injection moulded products with sealing by plastic-injection.
A kind of hollow injection molding forming method, it is characterized in that: submodule driving device (8) is driven by rotation oil motor,
Or electrical motor driven or oil cylinder drive.
A kind of hollow injection molding forming method, it is characterized in that: injection mechanism (6) can be it is same penetrate platform, can also be with
It is made of multiple platforms of penetrating.
A kind of hollow injection molding forming method, it is characterized in that: molding hollow product can be identical for different material
The product of color, or be the product of identical material different colours, or be the product of different colours different material, or be same color
The product of identical material forms.
The present invention relates to a kind of hollow injection molding forming methods, are mainly used in certain hollow injection-molded items for needing to seal,
In order to which package technique core can obtain juror and be familiar with this those skilled in the art in just this mould, analysis, schema are further appreciated that
Example then needs the circular hollow floating ball plastic parts sealed to be described in detail with one, but and this non-limiting hollow injection forming technique.
