Description

Technical Field

[0001] The utility model relates to a glue injection mold, in particular to a constant temperature glue injection mold. Background Art

[0002] At present, a Chinese patent with authorization announcement number CN206201379U discloses a glue injection mold, including a lower pressing block, a placing component arranged on the lower pressing block for placing a carbon ring and a copper strip, and an upper pressing block arranged on the placing component. The lower pressing block and the placing component enclose a glue injection space for connecting the carbon ring and the copper strip, and a glue injection port is opened on the lower pressing block, and the glue injection port is connected to the glue injection space.

[0003] This glue injection mold connects the carbon ring and the copper strip by setting a special glue injection mold. The fixture itself has a simple structure and can effectively improve the glue injection efficiency and quality of the carbon ring and the copper strip. However, this glue injection mold cannot maintain a constant temperature for the glue. When the glue temperature is too high, the glue is easily damaged. When the glue temperature is too low, the fluidity of the glue is poor, so it is inconvenient to use. Utility Model Content

[0004] In view of this, the purpose of the utility model is to provide a constant temperature injection mold, which adjusts the temperature by setting a heating pipe layer and a cooling pipe layer to achieve a constant temperature effect, improve the injection quality and reduce the glue residue on the injection port and the outlet.

[0005] In order to solve the above technical problems, the technical solution of the utility model is: a constant temperature injection mold, including a mold plate, a glue injection port and a glue outlet port are provided on the mold plate, a flow channel for connecting the glue injection port and the glue outlet port is provided on the mold plate, and a heating pipe layer and a cooling pipe layer are provided on the mold plate, and the heating pipe layer and the cooling pipe layer are located between the glue injection port and the glue outlet.

[0006] To implement the above technical solution, hot oil is injected into the heating pipe layer to heat the flow channel. At the same time, cold water is injected into the cooling pipe layer to cool the flow channel. When the temperature of the glue is too high, the hot oil flow rate is reduced and the cold water flow rate is increased to achieve cooling; when the temperature of the glue is too low, the hot oil flow rate is increased and the cold water flow rate is reduced to achieve heating, thereby achieving a constant temperature effect.

[0007] As a preferred embodiment of the present invention, the heating pipe layer includes a heating inlet, a heating outlet, a first heating channel, a turning channel, and a second heating channel. The heating inlet and the heating outlet are both opened on the mold plate. One end of the first heating channel is connected to the heating inlet, and the other end of the first heating channel is connected to the turning channel. One end of the second heating channel is connected to the turning channel, and the other end of the second heating channel is connected to the heating outlet.

[0008] To implement the above technical solution, hot oil enters the first heating channel from the heating inlet, then passes through the turning channel and the second heating channel, and is finally discharged from the heating outlet to realize hot oil circulation. Through the turning effect of the turning channel, multiple second heating channels and multiple turning channels can be set on the mold plate to realize rapid heating of the convection channel.

[0009] As a preferred solution of the utility model, the cooling pipe layer includes a cooling inlet, a cooling outlet, a first cooling pipe, a heat dissipation component, and a second cooling pipe. The cooling inlet and the cooling outlet are both opened on the mold plate. One end of the first cooling pipe is connected to the cooling inlet, and the other end of the first cooling pipe is connected to the heat dissipation component. One end of the second cooling pipe is connected to the heat dissipation component, and the other end is connected to the cooling outlet. The heat dissipation component is close to the flow channel.

[0010] To implement the above technical solution, cold water enters the first cooling pipe from the cooling inlet, then enters the second cooling pipe after passing through the heat dissipation component, and finally is discharged from the cooling outlet to realize cold water circulation. The flow channel is close to the heat dissipation component, so that the glue in the flow channel can be cooled quickly.

[0011] As a preferred solution of the utility model, the heat dissipation assembly includes a first branch hole, a second branch hole, a fixing seat, and a connecting pipe. The fixing seat is fixedly connected to the mold plate, a connecting hole is provided on the fixing seat, the connecting pipe is fixed in the connecting hole and connected to the glue outlet, the first branch hole and the second branch hole are both provided on the fixing seat, one end of the first branch hole is connected to the first cooling pipe, and the other end is connected to the connecting hole, one end of the second branch hole is connected to the connecting hole, and the other end is connected to the second cooling pipe.

[0012] To implement the above technical solution, cold water is injected from the first cooling pipe into the first branch hole, then from the first branch hole into the connecting hole, then from the connecting hole into the second branch hole, and then discharged from the cold water outlet along the second cooling pipe. The glue enters the connecting pipe from the glue outlet and is then discharged from the connecting pipe. Since the cold water contacts the surface of the connecting pipe, the glue can be quickly cooled down.

[0013] As a preferred solution of the utility model, a first spiral sheet and a second spiral sheet are arranged on the outer wall of the connecting tube, and the first spiral sheet and the second spiral sheet are distributed along the axis of the exchange tube.

[0014] To implement the above technical solution, through the guiding effect of the first spiral sheet and the second spiral sheet, the cold water has a tendency of spiral conduction in the connecting hole, so that the connecting pipe is in contact with the cold water more comprehensively, thereby improving the cooling effect. At the same time, the first spiral sheet and the second spiral sheet have a heat conducting effect, thereby further improving the heat dissipation of the connecting pipe.

[0015] As a preferred solution of the utility model, the pitch of the first spiral sheet and the second spiral sheet is greater than or equal to the inner diameter of the first branch hole and the second branch hole, and the inner diameter of the first branch hole and the second branch hole are equal.

[0016] By implementing the above technical solution, cold water enters the first spiral sheet along the first branch hole, moves to the end of the first spiral sheet and then enters the second spiral sheet, and finally is discharged from the second branch hole, so that the cold water conduction is more stable and orderly, and the heat dissipation efficiency and cooling effect of the connecting pipe are improved.

[0017] As a preferred solution of the utility model, a pressing plate is fixedly connected to the mold plate, a connecting hole is opened on the pressing plate, an end of the fixing seat extends out from the connecting hole, and an inner wall of the connecting hole contacts the fixing seat.

[0018] The above technical solution is implemented to make the connection between the fixing seat and the mold plate more stable and tight, and less likely to cause water leakage and oil leakage. BRIEF DESCRIPTION OF THE DRAWINGS
