Description

Technical Field

[0001] This utility model relates to the field of mold technology, and more specifically, to a mold with high-efficiency heat dissipation. Background Technology

[0002] Molds are various molds and tools used in industrial production to obtain desired products through methods such as injection molding, blow molding, extrusion, die casting, forging, smelting, and stamping. In short, molds are tools used to make shaped objects. These tools are composed of various parts, and different molds are composed of different parts. They mainly achieve the processing of the shape of objects by changing the physical state of the material being molded, and are often referred to as the "mother of industry".

[0003] After material is fed into the mold, existing molds typically use cooling pipes laid inside the mold to remove heat in a timely manner and accelerate the cooling speed of the material. However, after long-term use, the pipes may become clogged due to impurities, scale, etc. in the water, which will prevent the cooling medium from flowing normally. At the same time, the limited outer surface area of ​​the cooling pipes and the small contact area with the mold restrict the speed at which heat is transferred from the mold to the cooling medium, thus affecting the cooling efficiency. Utility Model Content

[0004] In order to overcome the above-mentioned defects of the prior art, the embodiments of this utility model provide a mold with high-efficiency heat dissipation. The technical problem to be solved by this utility model is that the outer surface area of ​​the cooling pipe is limited and the contact area with the mold is small, which limits the speed at which heat is transferred from the mold to the cooling medium, thereby affecting the cooling efficiency.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A high-efficiency heat dissipation mold includes an upper mold and a lower mold, with a positioning mechanism between the upper and lower molds. A first water outlet pipe is fixed and connected to the outer side of the upper mold, and a water inlet pipe and a second water outlet pipe are fixed and connected to the outer side of the lower mold. An upper cavity is fixedly installed inside the upper mold, and multiple injection channels are fixed and connected to the top surface of the upper mold, with each injection channel connected to the upper cavity. A lower cavity is fixedly installed inside the lower mold, and multiple heat-conducting plates are fixedly installed on the outer sides of both the lower and upper cavities. A square groove is formed inside the upper mold, and a square block is fixedly installed on the top surface of the lower mold, with the square block fitting into the square groove. Square airbags are installed on both outer sides of the square block, and multiple square airbags are connected. An air injection mechanism is provided inside the lower mold, and the air injection mechanism is connected to each square airbag.

[0007] like Figure 1-3As shown, the specific implementation method is as follows: By setting a positioning mechanism, the lower mold and the upper mold can be accurately positioned, thereby aligning the upper cavity and the lower cavity. By setting a water inlet pipe, a second water outlet pipe, a first water outlet pipe, an air injection mechanism, a square air bag, and a square groove, the square block is locked in the square groove, and the square air bag is inflated, thereby achieving a seal between the upper mold and the lower mold. Then, water is injected into the lower mold through the water inlet pipe until the upper mold and the lower mold are filled with cooling water, and the hot water is discharged through the first water outlet pipe, thereby achieving rapid heat dissipation between the upper cavity and the lower cavity.

[0008] In a preferred embodiment, the gas injection mechanism includes multiple gas injection boxes, which are symmetrically installed on the bottom wall of the lower mold. Each gas injection box is connected to one of the square air bladders. Each gas injection box has a piston that is elastically slidably connected inside. A push rod is fixedly installed on the top surface of each piston. Multiple pressure rods are symmetrically installed on the top wall of the upper mold, and the bottom surface of each pressure rod abuts against the top surface of the corresponding push rod.

[0009] In a preferred embodiment, each of the air-filled boxes is fixed to and connected to a connecting pipe on its outer side, and each connecting pipe is connected to one of the square airbags.

[0010] In a preferred embodiment, a plurality of spring telescopic rods are symmetrically installed on the bottom wall of each of the gas injection boxes, and the other end of each spring telescopic rod is fixedly connected to the bottom surface of the piston.

[0011] In a preferred embodiment, the positioning mechanism includes a plurality of positioning pins, which are symmetrically installed on the outer side of the upper mold. A plurality of positioning seats are symmetrically installed on the outer side of the lower mold, and each positioning pin is engaged in the corresponding positioning seat.

[0012] In a preferred embodiment, each of the heat-conducting plates has multiple through slots.

[0013] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0014] 1. This utility model, by setting up a square groove, a square airbag, a square block, an upper cavity, a lower cavity, a water inlet pipe, and a first water outlet pipe, realizes that when the upper mold slides downward, the pressure rod pushes the push rod to slide, and the piston pushes the air in the air injection box into the square airbag. Thus, the expansion of the square airbag seals the upper mold and the lower mold. Then, coolant is injected through the water inlet pipe to cover the upper cavity and the lower cavity, increasing the heat exchange area and thus achieving efficient heat dissipation. At the same time, hot water rises and cold water sinks, so that hot water can be discharged through the first water outlet pipe.

[0015] 2. This utility model achieves precise alignment between the upper and lower molds by setting positioning pins, positioning seats and other devices, thereby facilitating the sliding of the push rod by the pressure rod.

[0016] In summary, this utility model is simple to operate and can achieve a seal between the upper and lower molds. At the same time, the upper and lower cavities can be wrapped with coolant to increase the heat exchange area and thus achieve efficient heat dissipation. Attached Figure Description

Detailed Implementation

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0022] Reference Figure 1-3A high-efficiency heat dissipation mold includes an upper mold 1 and a lower mold 2. A positioning mechanism is provided between the upper mold 1 and the lower mold 2. A first water outlet pipe 4 is fixed and connected to the outer side of the upper mold 1. A water inlet pipe 3 and a second water outlet pipe 5 are fixed and connected to the outer side of the lower mold 2. An upper cavity 11 is fixedly installed inside the upper mold 1. Multiple injection channels 8 are fixed and connected to the top surface of the upper mold 1, and each injection channel 8 is connected to the upper cavity 11. A lower cavity 9 is fixedly installed inside the lower mold 2. Multiple heat-conducting plates 10 are fixedly installed on the outer side of both the lower cavity 9 and the upper cavity 11. A square groove 12 is opened inside the upper mold 1. A square block 13 is fixedly installed on the top surface of the lower mold 2 and is locked in the square groove 12. Square airbags 19 are installed on both outer sides of the square block 13, and multiple square airbags 19 are connected. An air injection mechanism is provided inside the lower mold 2, and the air injection mechanism is connected to each square airbag 19.

[0023] like Figure 1-3 As shown, the specific implementation method is as follows: By setting a positioning mechanism, the lower mold 2 and the upper mold 1 can be accurately positioned, thereby aligning the upper cavity 11 and the lower cavity 9. By setting a water inlet pipe 3, a second water outlet pipe 5, a first water outlet pipe 4, an air injection mechanism, a square air bag 19, and a square groove 12, the square block 13 is locked in the square groove 12, and the square air bag 19 is inflated, thereby achieving a seal between the upper mold 1 and the lower mold 2. Then, water is injected into the lower mold 2 through the water inlet pipe 3 until the upper mold 1 and the lower mold 2 are filled with cooling water, and the hot water is discharged through the first water outlet pipe 4, thereby achieving rapid heat dissipation between the upper cavity 11 and the lower cavity 9.

[0024] The air injection mechanism includes multiple air injection boxes 14, which are symmetrically installed on the bottom wall of the lower mold 2. Each air injection box 14 is connected to one of the square air bags 19. Each air injection box 14 has a piston 16 elastically slidably connected inside. Each piston 16 has a push rod 17 fixedly installed on its top surface. Multiple pressure rods 18 are symmetrically installed on the top wall of the upper mold 1, and the bottom surface of each pressure rod 18 abuts against the top surface of the corresponding push rod 17. It should be noted that, through the positioning mechanism installed on the outside of the upper mold 1, the pressure rod 18 can abut against the push rod 17 each time, thereby pushing the push rod 17 to slide downward, which in turn drives the piston 16 to slide, injecting the air in the air injection box 14 into the square air bag 19.

[0025] Each air-filled box 14 is fixed to the outside and connected to a connecting pipe 20, and each connecting pipe 20 is connected to one of the square airbags 19.

[0026] Multiple spring telescopic rods 15 are symmetrically installed on the bottom wall of each gas injection box 14, and the other end of each spring telescopic rod 15 is fixedly connected to the bottom surface of the piston 16. The spring telescopic rods 15 facilitate the reset of the piston 16.

[0027] The positioning mechanism includes multiple positioning pins 6, which are symmetrically installed on the outside of the upper mold 1. Multiple positioning seats 7 are symmetrically installed on the outside of the lower mold 2, and each positioning pin 6 is locked in the corresponding positioning seat 7. Multiple through slots are opened on each heat conduction plate 10.

[0028] When this utility model is used, the upper mold 1 can be driven to slide downward by the hydraulic cylinder, and the upper mold 1 and the lower mold 2 can be aligned and fitted by the locking of the positioning pin 6 and the positioning seat 7. At this time, the upper cavity 11 and the lower cavity 9 are fitted together. Then, the material can be injected into the upper cavity 11 through multiple injection channels 8. The material fills the upper cavity 11 and the lower cavity 9, and finally forms the finished product.

[0029] As the upper mold 1 slides downward, the push rod 17 is pushed downward by the pressure rod 18, thereby pushing the air in the air injection box 14 into the square air bladder 19 through the sliding of the piston 16. Then, as the upper mold 1 and the lower mold 2 fit together, the square block 13 is locked in the square groove 12, and the square air bladder 19 on the outside of the square block 13 expands, thereby achieving a seal between the upper mold 1 and the lower mold 2.

[0030] Next, coolant can be injected into the lower mold 2 through the water inlet pipe 3. At the same time, the heat of the material in the upper cavity 11 and the lower cavity 9 is conducted to the coolant through the heat conduction plate 10 and participates in heat exchange. As the coolant is continuously injected, the coolant will gradually fill the upper mold 1 and the lower mold 2, enveloping the upper cavity 11 and the lower cavity 9, increasing the heat exchange area, thereby achieving efficient heat dissipation. At the same time, hot water rises and cold water sinks, so the hot water can be discharged through the first water outlet pipe 4. After the material has cooled down, all the coolant in the upper mold 1 and the lower mold 2 can be discharged through the second water outlet pipe 5, so that the upper mold 1 and the lower mold 2 can be separated and the finished product can be taken out.

[0031] The foregoing description only illustrates certain exemplary embodiments of the present invention. Undoubtedly, those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
