[0002] Injection molding is to use an external auxiliary heat source to melt plastic particles, inject the molten plastic liquid into the mold with the help of an injection molding machine, and then cool and solidify to form the required plastic products. The whole process includes five steps: adding materials → melting → pressure injection → mold cooling → mold opening and taking out parts;

[0003] Among the five links of the injection molding process of the injection molding machine mentioned above, pressure injection and mold cooling both require cooling. Among them, the pressure injection cooling system is mainly used to cool the hydraulic oil or coolant, and the mold cooling process is mainly used to cool the injection molded products. Considering the influence of multiple mold cavities and mold coolant supply arrangement on the overall cooling efficiency and cooling effect in the processing station, the coolant inlet and outlet of the prior art usually adopts the inlet and outlet supply pipelines arranged in units for real-time control. However, when faced with more or fewer local control scenarios, it is often impossible to achieve a fast control response, and it is often necessary to cooperate with manual control and management of a single valve body pipeline of a single unit, so that its arrangement method limits the control accuracy of the equipment.

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0022] Please refer to Figures 1-3 , for a further description of the embodiments of the present utility model;

[0023] A cooling water inlet and outlet control device for a bottle cap injection molding machine, comprising a coil pipe seat 1 and a valve pipe 2. The valve pipe 2 is penetrated and arranged at one end of the coil pipe seat 1. A liquid storage chamber 7 is arranged in the coil pipe seat 1. At one end of the coil pipe seat 1 opposite to the valve pipe 2, a liquid pipe socket 4 and an air valve pipe 5 are symmetrically arranged, and the liquid pipe socket 4 is communicated with the liquid storage chamber 7;

[0024] A shunt pipe 15 is arranged in the valve pipe 2. The shunt pipe 15 communicates with the liquid storage chamber 7. A plurality of valve orifice plugs 6 are penetrated and arranged on the shunt pipe 15;

[0025] An air pipe 11 is arranged adjacent to the side of the shunt pipe 15. The air pipe 11 is slidably matched with the valve pipe 2. A connecting pipe fitting 12 is inserted between each valve orifice plug 6 and the air pipe 11. A column pipe plug 13 is penetrated between each valve orifice plug 6 and the air pipe 11. And the air pipe 11 and the column pipe plug 13 are both communicated with the air valve pipe 5.

[0026] In this device, the valve orifice plugs 6 distributed on the valve pipe 2 are mainly used as the shunt channel interfaces from the liquid storage chamber 7 to the shunt pipe 12 to each coolant pipeline in the injection molding machine, so that the device can use the collective valve orifice plugs 6 to unitize the layout of the coolant pipelines;

[0027] During shunt control, the air pipe 11 can slide axially in the valve pipe 2 to adjust the position of the connecting pipe fitting 12 at the docking end of the valve orifice plug 6, so as to open and close the connection between the valve orifice plug 6 and the shunt pipe 12 through the movement of the connecting pipe fitting 12. At the same time, due to the synchronous linkage of the air pipe 11 and each connecting pipe fitting 12, the management and control of the valve orifices of the entire unit valve orifice plug 6 can be realized. And further, by connecting an external air source to the air valve pipe 5, the column pipe plug 13 under a single valve orifice plug 6 can be controlled pneumatically, which further improves the operability of the device;

[0028] Compared with the prior art, due to the use of a unitized pipeline layout method, the operability of the control device for inlet and outlet control is poor. In the face of more or fewer local control scenarios of pipelines, it is often impossible to achieve a rapid control response. This control device can combine pneumatic control to complete the overall valve body inlet and outlet control and local valve body control in the unit, improving the practicability of the device.

[0029] Preferably, a main machine box 3 is fixed on one side of the coil pipe seat 1. A hydraulic pump 9 is fixed in the main machine box 3. The hydraulic pump 9 communicates with the liquid storage chamber 7. This inlet and outlet control device mainly completes the coolant feeding from the liquid pipe socket 4 to the liquid storage chamber 7 through the braking of the hydraulic pump 9 in the main machine box 3.

[0030] Preferably, a transfer valve pipe 8 extends from the pneumatic pipe 11 into the coil pipe base 1. The transfer valve pipe 8 communicates with the liquid chamber 7. The transfer valve pipe 8 is used to connect the air valve pipe 5, the pneumatic pipe 11 and the liquid chamber 7, so that when the valve body is in a normal opening and closing state, the coolant in the pipeline can be cleared along the pipeline by the filled air pressure for subsequent inflow and outflow management.

[0031] Preferably, a pressure relief plug pipe 10 is inserted on one side of the connection end of the transfer valve pipe 8 and the liquid chamber 7. The provided pressure relief plug pipe 10 is used to facilitate the later maintenance personnel to remove the gas in the pipeline by opening the pressure relief plug pipe 10, so as to reduce the pipeline air pressure and facilitate the subsequent pipeline maintenance operation.

[0032] Preferably, the connecting pipe fitting 12 is a double-ended hinged sliding structure, and the connecting pipe fitting 12 is connected in series at the valve port on-off of the valve port plug 6. As Figure 3 shown, the double-ended hinged sliding enables the connecting pipe fitting 12 to complete the axial position change in cooperation with the pneumatic pipe 11 when the pneumatic pipe 11 feeds and slides, so as to realize linkage in cooperation with the movement of the pneumatic pipe 11 and improve the structural stability when the entire pneumatic pipe 11 and the connecting pipe fitting 12 move.

[0033] Preferably, a cross-shaped valve port plate member is arranged at the connection end of the connecting pipe fitting 12 and the valve port plug 6. In the structure, the hinged movement of the connecting pipe fitting 12 and the opening and closing control of the valve port plug 6 and the shunt pipe 15 are mainly realized by the rotation of the cross-shaped valve port plate member driven by the connecting pipe fitting 12 during the hinged movement to switch the opening and closing states between the valve port plug 6 and the shunt pipe 15.

[0034] Preferably, a slide rail groove 14 is provided by grooving on the outside of the connection end of the connecting pipe fitting 12 and the pneumatic pipe 11. Further, the linkage between the connecting pipe fitting 12 and the pneumatic pipe 11 is restricted in the slide rail groove 14 by the provided slide rail groove 14 to improve the movement accuracy and stability of the pneumatic pipe 11.

[0035] Preferably, the column pipe plug 13 is a pneumatic axial valve port opening and closing structure. With the axial valve port structure cooperating with the pneumatic opening and closing control, when the column pipe plug 13 moves axially in a pneumatic manner, the opening and closing control of the valve port plug 6 can be completed by the axial expansion and contraction of the column pipe plug 13.

[0036] The implementation mode of the device is as follows:

[0037] In this device, the valve port plugs 6 distributed on the valve pipe 2 are mainly used as the shunt channel interfaces from the liquid chamber 7 to each coolant pipeline in the injection molding machine through the connecting pipe fitting 12, so that the device can use the collective valve port plugs 6 to unitize the layout of the coolant pipelines. Then, the liquid pipe socket 4 is connected to the coolant source pipeline, and the air valve pipe 5 is connected to the pneumatic air source;

[0038] During shunt control, the coolant in the liquid storage tank 7 is pressurized and conveyed into the shunt pipe 15 through the braking of the hydraulic pump 9, and is output along each valve port plug 6. During inlet and outlet control, the air pressure transferred by the air valve pipe 5 can be used in a pneumatic control manner to act on the pneumatic pipe 11. The piston sliding in the inflated state of the pneumatic pipe 11 is used to change its position in the valve pipe 2, thereby driving multiple connecting parts 12 to move hingedly along with the position of the pneumatic pipe 11 until the valve port plate in the pneumatic pipe 11 completes the opening and closing of the valve port plug 6 to the shunt pipe 15. At the same time, the column pipe plug 13 under the valve port plug 6 at a specified position can be independently pneumatically controlled. The valve body in the column pipe plug 13 is inserted into the connection end of the valve port plug 6 and the shunt pipe 15 through pneumatic feeding to complete the opening and closing control, realizing the inlet and outlet control of the coolant pipeline under the entire unit.

[0039] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention and not to limit them. Although the present invention has been described in detail with reference to the preferred embodiments, those of ordinary skill in the art should understand that the technical solutions of the present invention can be modified or equivalently replaced without departing from the purpose and scope of the technical solutions of the present invention, and they should all be covered by the scope of the claims of the present invention.
