Description

Technical Field

[0001] This application relates to the field of injection molding, and more specifically, to an injection molding apparatus with high-efficiency cooling. Background Technology

[0002] Injection molding is a method of industrial product manufacturing. Products are typically produced using rubber injection molding and plastic injection molding. Injection molding can also be divided into injection compression molding and die casting. An injection molding machine (or simply injection molding machine) is the main molding equipment used to create various shapes of plastic products from thermoplastic or thermosetting materials using plastic molds. Injection molding is achieved through an injection molding machine and molds. Injection molding, also known as injection molding, is a molding method that combines injection and molding.

[0003] Currently, in the process of using injection molding molds, in order to accelerate the cooling and molding of products, there are often cooling water circulation channels inside them. This will undoubtedly increase the thickness of the mold and affect the cooling and temperature reduction. Cooling by water alone is not efficient enough, and the molded products are inconvenient to remove quickly. Utility Model Content

[0004] To overcome the above deficiencies, this application provides an injection molding apparatus with high-efficiency cooling, which aims to improve the problems mentioned in the background art.

[0005] This application provides an efficient cooling injection molding apparatus including a cooling component and an auxiliary component.

[0006] The cooling assembly includes a base, a lower mold, an upper mold, a guide post, a heat-conducting plate, a cooling pipe, an electric telescopic rod, and a fan. The lower mold is disposed on the top of the base, the guide post is fixedly connected to the base, the upper mold is slidably sleeved on the guide post, the heat-conducting plate is fixedly connected to both the lower mold and the upper mold, the cooling pipe is fixedly inserted through the heat-conducting plate, the electric telescopic rod is fixedly connected to the base, the electric telescopic rod is fixedly connected to the upper mold, and the fan is disposed at the end of the upper mold.

[0007] The auxiliary component includes a transmission rod, an elastic element, and a push rod. The elastic element is disposed within the base. The transmission rod is fixedly connected to the elastic element. The push rod is fixedly connected to the elastic element. The push rod slides through the lower mold. The transmission rod slides through the base.

[0008] In one specific implementation, the upper mold has an injection port and a through hole that is adapted to the guide post.

[0009] In the above implementation process, an injection port is set to inject high-temperature injection liquid into the mold, and the upper mold is slidably fitted with a guide post through a through hole.

[0010] In one specific implementation, a connecting plate is fixedly connected to the side of the upper mold, and the connecting plate is fixedly connected to the electric telescopic rod, with the transmission rod and the connecting plate aligned.

[0011] In the above implementation process, a connecting plate is set up to connect the upper mold and the electric telescopic rod on the one hand, and to push the transmission rod by pressing down on the other hand.

[0012] In one specific implementation, the cooling pipe is S-shaped and has a connecting head.

[0013] In the above implementation process, by setting up S-shaped cooling pipes, heat exchange is facilitated for cooling, and the connector makes it easy to connect to external pipes.

[0014] In one specific implementation, the base has a connecting groove, and both the transmission rod and the elastic element are located within the connecting groove.

[0015] In one specific implementation, the elastic element includes a spring and a sliding plate, the spring being disposed within the communicating groove, the sliding plate being slidably disposed within the communicating groove, the transmission rod being fixedly connected to the sliding plate, and the top rod being fixedly connected to the sliding plate.

[0016] In the above implementation process, by setting up a spring and a sliding plate, when compressed, the transmission rod pushes the sliding plate down to compress the spring, and the sliding plate drives the top rod down. When the transmission rod is not compressed, the elastic recovery of the spring pushes the sliding plate, so that the sliding plate drives the top rod up to eject the molded product, which is conducive to quick material removal.

[0017] In one specific implementation, the top of the transmission rod is higher than the top rod, and there are two transmission rods arranged symmetrically.

[0018] In the above process, the two symmetrically arranged transmission rods are first squeezed by the connecting plate, and then the transmission drives the top rod to move down together.

[0019] In one specific implementation, the base has a mounting block on its side and mounting holes.

[0020] In the above implementation process, installation is facilitated by setting up mounting blocks and opening mounting holes.

[0021] Beneficial effects: This application provides a highly efficient cooling injection molding device. By setting up a base, lower mold, upper mold, guide pillar, heat-conducting platen, cooling pipe, electric telescopic rod and fan, multiple heat-conducting plates are used to conduct heat and dissipate heat to the mold. At the same time, cooling water is introduced through the cooling pipe to cool down the mold and the fan blows air to accelerate air circulation, thereby achieving rapid cooling and improving heat dissipation efficiency. By setting up a transmission rod, elastic element and ejector rod, it is possible to easily assist in ejecting the molded product and facilitate material removal. Attached Figure Description

Detailed Implementation

[0028] The technical solutions in the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments.

[0029] Please see Figures 1-4 This application provides an injection molding apparatus with high-efficiency cooling, including a cooling component 100 and an auxiliary component 200.

[0030] Please see Figure 1 , 2 3. The cooling assembly 100 includes a base 110, a lower mold 120, an upper mold 130, a guide post 140, a heat-conducting plate 150, a cooling pipe 160, an electric telescopic rod 180, and a fan 190. The lower mold 120 is disposed on the top of the base 110. The guide post 140 is fixedly connected to the base 110. The upper mold 130 is slidably sleeved on the guide post 140. Both the lower mold 120 and the upper mold 130 are fixedly connected to the heat-conducting plate 150. The cooling pipe 160 is fixedly inserted through the heat-conducting plate 150. The electric telescopic rod 180 is fixedly connected to the base 110 and the upper mold 130. The fan 190 is disposed at the end of the upper mold 130.

[0031] The upper mold 130 has an injection port 131 and a through hole that is compatible with the guide post 140. The injection port 131 is used to inject high-temperature injection liquid into the mold. The upper mold 130 and the guide post 140 are slidably fitted together through the through hole.

[0032] Specifically, a connecting plate 132 is fixedly connected to the side of the upper mold 130. The connecting plate 132 is fixedly connected to the electric telescopic rod 180. The transmission rod 210 and the connecting plate 132 are aligned. By setting the connecting plate 132, it is used to connect the upper mold 130 and the electric telescopic rod 180 on the one hand, and to push the transmission rod 210 by pressing down on the other hand.

[0033] It should be noted that the cooling pipe 160 is S-shaped and is equipped with a connector 161. The S-shaped cooling pipe 160 facilitates heat exchange and cooling, and the connector 161 makes it easy to connect to external pipes.

[0034] Please see Figure 1 , 2 4. The auxiliary component 200 includes a transmission rod 210, an elastic element 220 and a push rod 230. The elastic element 220 is disposed in the base 110. The transmission rod 210 is fixedly connected to the elastic element 220. The push rod 230 is fixedly connected to the elastic element 220. The push rod 230 slides through the lower mold 120. The transmission rod 210 slides through the base 110.

[0035] The base 110 has a connecting groove 111, and the transmission rod 210 and the elastic element 220 are both located in the connecting groove 111.

[0036] In this embodiment, the elastic element 220 includes a spring 221 and a sliding plate 222. The spring 221 is disposed in the communicating groove 111, and the sliding plate 222 is slidably disposed in the communicating groove 111. The transmission rod 210 is fixedly connected to the sliding plate 222, and the push rod 230 is fixedly connected to the sliding plate 222. By setting the spring 221 and the sliding plate 222, when compressed, the transmission rod 210 pushes the sliding plate 222 down to compress the spring 221, and the sliding plate 222 drives the push rod 230 down. When the transmission rod 210 is not compressed, the elastic recovery effect of the spring 221 pushes the sliding plate 222, so that the sliding plate 222 drives the push rod 230 up to eject the molded product, which is conducive to quick material removal.

[0037] It should be noted that the top of the transmission rod 210 is higher than the top rod 230, and there are two transmission rods 210 arranged symmetrically. The two symmetrically arranged transmission rods 210 will be squeezed by the connecting plate 132 first, and then the transmission will drive the top rod 230 to move down together.

[0038] In one specific implementation, the base 110 has a mounting block 112 on its side and a mounting hole, which facilitates installation.

[0039] The working principle of this high-efficiency cooling injection molding device is as follows: When in use, the electric telescopic rod 180 is activated, causing the connecting plate 132 and the upper mold 130 to move downwards. The downward movement of the connecting plate 132 compresses the transmission rod 210, which in turn pushes the sliding plate 222 downwards, compressing the spring 221. The sliding plate 222 then drives the ejector rod 230 downwards. High-temperature injection molding liquid is then injected into the mold through the injection port 131. Multiple heat-conducting plates 150 conduct heat to the mold, while cooling water is introduced through the cooling pipe 160 to lower the temperature and the fan 190 blows air to accelerate airflow, thus achieving rapid cooling and improving heat dissipation efficiency. Finally, the electric telescopic rod 180 is activated, causing the connecting plate 132 and the upper mold 132 to move upwards. The elastic recovery of the spring 221 pushes the sliding plate 222, causing it to drive the ejector rod 230 upwards to eject the molded product, facilitating rapid material removal.

[0040] It should be noted that the specific model and specifications of the electric telescopic pole 180 need to be selected and determined according to the actual specifications of the device. The specific selection calculation method adopts the existing technology in this field, so it will not be described in detail here.

[0041] The power supply and operating principle of the electric telescopic pole 180 are clear to those skilled in the art and will not be described in detail here.

[0042] It will be apparent to those skilled in the art that this application is not limited to the details of the exemplary embodiments described above, and that this application can be implemented in other specific forms without departing from the spirit or essential characteristics of this application. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this application is defined by the appended claims rather than the foregoing description. Thus, all variations falling within the meaning and scope of equivalents of the claims are intended to be included within this application. No reference numerals in the claims should be construed as limiting the scope of the claims.
