Description

Technical Field

[0001] The utility model relates to a mold, in particular to a mold insert with a water cooling function. Background Art

[0002] With the development of the times, industrial production technology is also developing rapidly, and injection molds are also being used more and more in industrial production. In order to ensure rapid cooling of the workpiece, a water-cooling pipeline is usually set inside the insert. In addition, in order to ensure smooth demoulding, an air blowing pipeline is usually required to be set inside the insert. The current existing solution is to set water-cooling pipelines and air blowing pipelines at the same time, and set a fixing mechanism for fixing the water-cooling pipeline and the air blowing pipeline inside the insert. The above structure easily causes the insert to be too large and the structure to be not compact enough, which increases the production cost of the entire mold. It lacks competitiveness in the industrial field that emphasizes cost reduction and efficiency improvement, and is not conducive to large-scale promotion and industrial production.

When the heat dissipation liquid flows to the top of the inner core, since the tops of the two spiral grooves are connected to each other, the heat dissipation liquid flows into the heat dissipation channel formed by the other spiral groove and the inner cavity. At this time, the heat dissipation liquid flows downward in a spiral along the heat dissipation channel until the heat dissipation liquid flows into the liquid outlet channel, and then the heat dissipation liquid flows into the liquid outlet pipeline and flows out through the liquid outlet valve. The heat dissipation liquid flows in the heat dissipation channel. During the flow in the duct, the heat of the insert body is removed, cooling the insert body. Furthermore, the gas can enter the air inlet pipe through the air inlet valve and then into the air pipe. Finally, the gas is ejected through the air outlet at the top of the air pipe. Because the top of the air pipe and the inner wall of the air vent do not contact each other, the gas ejected from the air outlet can be ejected from the gap between the top of the air pipe and the inner wall of the air vent, blowing the workpiece away from the insert body. By providing a spiral groove on the inner core and arranging the air pipe inside the inner core, the dual functions of liquid cooling and air blowing are achieved. Compared with the existing design structure that requires separate water cooling pipes and air blowing pipes to achieve the corresponding functions, the structure is simpler. Since only a single inner core is required to take into account the formation of the heat dissipation flow channel and the fixing of the air pipe, not only is the structure more compact, but it is also more conducive to the miniaturization of the insert body. It has the advantage of compact structure. BRIEF DESCRIPTION OF THE DRAWINGS

[0019] In order to more clearly understand the technical means of the present invention and implement it according to the contents of the specification, the specific implementation methods of the present invention are further described in detail below in conjunction with the drawings and examples. The following examples are used to illustrate the present invention but are not used to limit the scope of the present invention.

[0020] This specific embodiment describes in detail the mold insert with water cooling function described in this application, such as Figure 1-Figure 3As shown, the mold insert with water cooling function includes: a template 1, an insert body 2, an inner core 3, an air pipe 4, a liquid inlet valve 5, a liquid outlet valve 6 and an air inlet valve 7. An inner cavity is provided in the insert body 2 along the vertical direction, the bottom end of the inner cavity is an open end, and a vent hole 8 connected to the inner cavity is provided at the top of the insert body 2. The inner core 3 is cylindrical, and two spiral grooves 9 are provided on the outer wall of the inner core 3 along the vertical direction. The tops of the two spiral grooves 9 are connected to each other, and the inner core 3 can be extended into the cavity and fit tightly into the cavity. The spiral groove 9 can be surrounded by the inner wall of the cavity to form a heat dissipation channel for liquid circulation. A connecting hole is provided in the middle of the inner core 3 along the vertical direction, and the hollow air pipe 4 is passed through the connecting hole and fits tightly into the connecting hole. An air outlet hole 10 is provided on the side wall of the top end of the air pipe 4, and the top end of the air pipe 4 can be extended into the vent hole 8. 4 does not contact the inner wall of the vent 8, the insert body 2 is fixed to the top surface of the template 1, and an inlet channel 11 and an outlet channel 12 are provided on the insert body 2. The first end of the inlet channel 11 is connected to the bottom end of one of the spiral grooves 9, and the first end of the outlet channel 12 is connected to the bottom end of the other spiral groove 9. The inlet valve 5, the outlet valve 6 and the air inlet valve 7 are fixed to the side of the template 1, and a liquid inlet pipeline 13, a liquid outlet pipeline 14 and an air inlet pipeline 15 are provided in the template 1. The first end of the liquid inlet pipeline 13 is connected to the second end of the liquid inlet channel 11, the second end of the liquid inlet pipeline 13 is connected to the liquid inlet valve 5, the first end of the liquid outlet pipeline 14 is connected to the second end of the liquid outlet channel 12, the second end of the liquid outlet pipeline 14 is connected to the liquid outlet valve 6, the first end of the air inlet pipeline 15 is connected to the bottom end of the air pipe 4, and the second end of the air inlet pipeline 15 is connected to the air inlet valve 7.During use, the heat dissipation liquid enters the liquid inlet pipe 13 through the liquid inlet valve 5 and flows into the liquid inlet channel 11, and then flows into the heat dissipation channel formed by one of the spiral grooves 9 and the inner cavity. The heat dissipation liquid flows upward along the heat dissipation channel. When the heat dissipation liquid flows to the top of the inner core 3, since the tops of the two spiral grooves 9 are connected to each other, the heat dissipation liquid flows into the heat dissipation channel formed by the other spiral groove 9 and the inner cavity. At this time, the heat dissipation liquid flows downward along the heat dissipation channel until the heat dissipation liquid flows into the liquid outlet channel 12, and then the heat dissipation liquid flows into the liquid outlet pipe 14 and flows out through the liquid outlet valve 6. The heat dissipation liquid can take away the heat of the insert body 2 during the flow in the heat dissipation channel, thereby cooling the insert body 2. External air can flow through the air inlet valve 7 into the air inlet pipe 15 and then into the air pipe 4. Finally, the air is ejected through the air outlet 10 at the top of the air pipe 4. Because the top of the air pipe 4 does not contact the inner wall of the air vent 8, the air ejected from the air outlet 8 can be ejected from the gap between the top of the air pipe 4 and the inner wall of the air vent 8, blowing the workpiece away from the insert body 2. By providing the spiral groove 9 on the inner core 3 and arranging the air pipe 4 within the inner core 3, the dual functions of liquid cooling and air blowing are achieved. Compared with the existing design structure that requires separate water cooling pipelines and air blowing pipelines to achieve the corresponding functions, the structure is simpler. Since only a single inner core 3 is required to simultaneously take into account the formation of the heat dissipation flow channel and the fixing of the air pipe 4, not only is the structure more compact, but it is also more conducive to the miniaturization of the insert body 2. It has the advantage of a compact structure.

[0021] In this embodiment, a first sealing ring 16 is optionally provided between the top of the inner core 3 and the inner wall of the inner cavity, and a second sealing ring 17 is provided between the top surface of the template 1 and the bottom end of the inner core 3. The insert body 2 is fixedly connected to the template 1 by bolts. The first sealing ring 16 and the second sealing ring 17 provide a seal to prevent the heat dissipating liquid from flowing into the space between the inner core 3 and the air pipe 4 and causing contamination.

[0022] Optionally, in this embodiment, the liquid inlet channel 11 and the liquid outlet channel 12 are obliquely formed and extend through the interior of the insert body 2. A third sealing ring 18 is provided at the second end of the liquid inlet channel 11, corresponding to the top surface of the template 1 and the bottom surface of the insert body 2. A fourth sealing ring 19 is provided at the second end of the liquid outlet channel 12, corresponding to the top surface of the template 1 and the bottom surface of the insert body 2. The third sealing ring 18 and the fourth sealing ring 19 can isolate air, preventing the mixing of air and heat dissipation liquid, which may cause bubbles to form in the heat dissipation channel and affect the heat dissipation effect.

[0023] Optionally, in this embodiment, a side wall at the top end of the trachea 4 is provided with an annular groove around the circumference of the trachea 4 , and the air outlet 10 is provided in the groove.

[0024] Optionally in this embodiment, a first limiting piece is provided at the bottom end of the inner core 3 along the radial protrusion of the inner core 3, a first limiting notch is provided at the bottom end of the inner cavity for the first limiting piece to be inserted into, a second limiting piece is provided at the bottom end of the trachea 4 along the radial protrusion of the trachea 4, and a second limiting notch is provided at the bottom end of the connecting hole for the second limiting piece to be inserted into.

[0025] Optionally, in this embodiment, the number of the air outlet holes 10 is four, and the four air outlet holes 10 are arranged at intervals in the circumferential direction around the air pipe 4 .

[0026] Optionally, in this embodiment, the top end of the trachea 4 is flush with the top end of the vent hole 8 .

[0027] In this embodiment, the outer wall of the trachea 4 below the annular groove is optionally in sealing contact with the inner wall of the vent hole 8, while the outer wall of the trachea 4 above the annular groove does not contact the inner wall of the vent hole 8. The sealing contact between the outer wall of the trachea 4 below the annular groove and the inner wall of the vent hole 8 can prevent gas from flowing back, so that gas can be blown out from the top of the vent hole 8.

[0028] Optionally, in this embodiment, the distance between the outer wall of the trachea 4 above the annular groove and the inner wall of the vent hole 8 is 0.02 mm.
