Description

Technical Field

[0001] This application relates to the technical field of molds, and in particular to a mold for forming a walkie-talkie base. Background Technology

[0002] In the field of modern communication equipment manufacturing, walkie-talkies are widely used in industries such as emergency rescue, logistics transportation, and security monitoring due to their instant communication and ease of operation. As the basic supporting component of the equipment, the walkie-talkie base not only needs to possess good mechanical strength and stability, but also needs to meet requirements such as precision assembly and a smooth appearance to ensure the installation and compatibility of the internal electronic components and the reliability of the overall structure.

[0003] In existing technologies, walkie-talkie base molding dies generally suffer from insufficient positioning accuracy during mold closing, and the front and rear templates are prone to misalignment, resulting in defects such as burrs and dimensional deviations on the outer surface of the base, which reduces production efficiency and product quality. Utility Model Content

[0004] To address the shortcomings of existing technologies, this application provides a walkie-talkie base molding die, which overcomes the deficiencies of existing technologies and aims to solve the problems that are common in walkie-talkie base molding dies, such as insufficient positioning accuracy during mold closing, easy misalignment of the front and rear templates, resulting in defects such as burrs and dimensional deviations on the outer surface of the base, which reduce production efficiency and product quality.

[0005] To achieve the above objectives, this application provides the following technical solution: a walkie-talkie base forming mold, comprising an upper fixed plate and a lower fixed plate, wherein the upper fixed plate and the lower fixed plate are spaced apart, and a front template and a rear template are provided between the upper fixed plate and the lower fixed plate. Both the front template and the rear template are provided with concave molds for forming the outer surface of the walkie-talkie base. Several guide rods are provided between the front template and the rear template. Cooling water pipes are provided inside both the front template and the rear template. A core-pulling mechanism is provided between the front template and the rear template.

[0006] By adopting the above technical solution, the upper and lower fixed plates serve as the basic frame of the mold, and are set at intervals to form the overall support structure of the mold. The concave molds on the front and rear templates cooperate to form the outer surface forming cavity of the walkie-talkie base. The guide rod ensures that the front and rear templates maintain precise alignment during the mold opening and closing process. Cooling water pipes are introduced to cool the mold and accelerate the solidification of the plastic melt. The core pulling mechanism pushes the formed base out of the mold when the mold is opened, thus completing the demolding.

[0007] As a preferred technical solution of this application, a guide sleeve is provided on the outer wall of several guide rods, the guide rod is provided on the front template, the guide sleeve is provided on the rear template, the guide rod and the guide sleeve are slidably engaged, and a positioning ring is provided on the front template for engaging with the positioning hole of the rear template.

[0008] By adopting the above technical solution, the guide rod is fixed on the front template, and the guide sleeve is installed inside the rear template. The two slide together to provide guidance for the opening and closing of the template. The positioning ring cooperates with the positioning hole of the rear template to accurately position the template during mold closing and prevent the template from shifting.

[0009] As a preferred embodiment of this application, the cooling water pipe includes a main flow channel and a secondary flow channel that are interconnected. The main flow channel is connected to an external cooling device, and the secondary flow channels are distributed within the front and rear templates.

[0010] By adopting the above technical solution, the main channel of the cooling water pipe is connected to the external cooling equipment, and the coolant flows into the secondary channel through the main channel. The secondary channel is distributed in a mesh pattern in the front and rear molds, and the heat of the mold is carried away through heat exchange, so that the plastic melt is cooled and formed quickly.

[0011] As a preferred technical solution of this application, the core-pulling mechanism includes an ejector plate, a push plate, and a reset rod. One side of the ejector plate passes through the rear template and engages with the punch. The ejector plate is fixedly connected to the push plate. One end of the reset rod is connected to the push plate, and the other end engages with the rear template, and is used to push the ejector plate and the push plate to reset when the mold is closed.

[0012] By adopting the above technical solution, when the mold is opened, the ejector plate pushes the punch under the action of power, and ejects the formed base from the rear template. The push plate is fixedly connected to the ejector plate and moves synchronously. When the mold is closed, the reset rod is squeezed by the front template, which pushes the push plate and ejector plate to reset, preparing for the next injection molding.

[0013] As a preferred technical solution of this application, the top surface of the upper fixed plate is provided with an injection port, and the bottom surface of the upper fixed plate is connected to a runner plate. The runner plate is provided with a main runner bushing, a branch runner and a gate. The main runner bushing is installed on the front mold plate and is used to connect the injection molding machine nozzle. The branch runner is provided in the front mold plate and is used to divide the plastic melt. The injection port connects the branch runner and the cavity mold.

[0014] By adopting the above technical solution, the injection molding machine nozzle injects the plastic melt into the runner plate through the main runner bushing. The melt enters the front mold plate through the branch runner and then flows into the concave mold cavity through the injection port. The gate controls the flow rate and filling time of the melt to ensure uniform filling of the cavity.

[0015] As a preferred technical solution of this application, a partition is provided on the top surface of the lower fixing plate to form the active space of the core-pulling mechanism.

[0016] By adopting the above technical solution, the partition on the lower fixed plate forms a closed space with other parts of the mold, providing an active area for the ejector plate, push plate and other parts of the core pulling mechanism, ensuring that the ejection and resetting actions are not interfered with.

[0017] As a preferred technical solution of this application, a number of support columns are provided between the upper fixing plate and the lower fixing plate.

[0018] By adopting the above technical solution, the support columns are evenly distributed between the upper and lower fixed plates, bearing the vertical pressure on the mold during the injection molding process and maintaining a stable distance between the upper and lower fixed plates.

[0019] Compared with the prior art, the beneficial effects of this application are as follows: 1. By sliding the guide rod and guide sleeve together, combined with the positioning structure of the positioning ring and positioning hole, the precise alignment of the front and rear templates when they are closed is ensured, avoiding product size deviations or surface defects caused by misalignment of the die, and ensuring the forming accuracy of the outer surface of the walkie-talkie base.

[0020] 2. The cooling water pipe adopts a design that connects the main flow channel and the secondary flow channel, so that the coolant circulates evenly in the template, quickly removes the heat of the molten plastic, reduces problems such as product deformation and shrinkage caused by uneven cooling, and improves the dimensional stability and surface smoothness of the base.

[0023] 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. All other embodiments obtained by those skilled in the art based on the embodiments of this application without creative effort are within the scope of protection of this application.

[0024] like Figure 1 - Figure 4 As shown, this embodiment provides a walkie-talkie base molding mold, including an upper fixing plate 1 and a lower fixing plate 2, which are spaced apart. A front template 3 and a rear template 4 are provided between the upper fixing plate 1 and the lower fixing plate 2. Both the front template 3 and the rear template 4 are provided with concave molds for forming the outer surface of the walkie-talkie base. Several guide rods 5 are provided between the front template 3 and the rear template 4. Cooling water pipes 6 are provided inside the front template 3 and the rear template 4. A core-pulling mechanism 7 is provided between the front template 3 and the rear template 4. The upper fixing plate 1 and the lower fixing plate 2 serve as the basic frame of the mold, and the spaced arrangement forms the overall support structure of the mold. The front and rear templates 3 and 4 are fitted together to form the outer surface molding cavity of the walkie-talkie base. The guide rod 5 ensures that the front and rear templates 4 are precisely aligned during the mold opening and closing process. Cooling water pipe 6 introduces coolant to cool the mold and accelerate the solidification of the plastic melt. The core-pulling mechanism 7 ejects the molded base from the mold when the mold is opened, completing the demolding. The combination of the upper and lower fixing plates 2 and the templates forms a rigid frame to ensure that the mold does not deform under injection pressure. The built-in cooling water pipe 6 accelerates the heat dissipation of the mold, shortens the molding cycle, and improves production efficiency. The core-pulling mechanism 7 realizes automated demolding, reduces manual intervention, and improves the degree of production automation.

[0025] In this embodiment, as Figure 2 As shown, guide sleeves 8 are provided on the outer walls of several guide rods 5. The guide rods 5 are set on the front template 3, and the guide sleeves 8 are set on the rear template 4. The guide rods 5 and guide sleeves 8 are slidably engaged. A positioning ring is provided on the front template 3. The positioning ring is used to engage with the positioning hole of the rear template 4 and is fixed to the front template 3 by the guide rods 5. The guide sleeves 8 are installed inside the rear template 4. The two are slidably engaged to provide guidance for the opening and closing of the template. The positioning ring engages with the positioning hole of the rear template 4 to accurately position the template during mold closing and prevent template offset. The engagement of the guide rods 5 and guide sleeves 8 ensures that the front and rear templates 4 are aligned and avoids product size deviations caused by misalignment.

[0026] In this embodiment, as Figure 2As shown, the cooling water pipe 6 includes a main channel and a secondary channel 9 that are interconnected. The main channel is connected to the external cooling equipment, and the secondary channels 9 are distributed in the front mold plate 3 and the rear mold plate 4. The cooling water pipe 6 is connected to the external cooling equipment through the main channel. The coolant flows into the secondary channel 9 through the main channel. The secondary channels 9 are distributed in the front and rear mold plates 4. Through heat exchange, the heat of the mold is removed, so that the plastic melt is cooled and formed quickly. The distributed design of the secondary channels 9 ensures that the temperature of each part of the mold is balanced, and avoids product deformation or shrinkage due to local overheating.

[0027] In this embodiment, as Figure 2 and Figure 3 As shown, the core-pulling mechanism 7 includes an ejector plate 10, a push plate 11, and a reset rod 12. One side of the ejector plate 10 passes through the rear template 4 and engages with the punch. The ejector plate 10 and the push plate 11 are fixedly connected. One end of the reset rod 12 is connected to the push plate 11, and the other end engages with the rear template 4. It is used to push the ejector plate 10 and the push plate 11 to reset when the mold is closed. When the mold is opened, the ejector plate 10, under the action of power, pushes the punch like the ejection mechanism of an injection molding machine, and ejects the molded base from the rear template 4. The push plate 11 is fixedly connected to the ejector plate 10 and moves synchronously. When the mold is closed, the reset rod 12 is squeezed by the front template 3, pushing the push plate 11 and the ejector plate 10 to reset, preparing for the next injection molding. The linkage between the ejector plate 10 and the push plate 11 realizes automatic ejection of the product, reducing the labor intensity of manual demolding.

[0028] In this embodiment, as Figure 1 and Figure 2 As shown, the top surface of the upper fixed plate 1 is provided with an injection port 13, and the bottom surface of the upper fixed plate 1 is connected to a runner plate 14. The runner plate 14 is provided with a main runner bushing, a branch runner, and a gate. The main runner bushing is installed on the front mold plate 3 and is used to connect the injection molding machine nozzle. The branch runner is set in the front mold plate 3 and is used to divide the plastic melt. The injection port 13 connects the branch runner and the cavity. The injection molding machine nozzle injects the plastic melt into the runner plate 14 through the main runner bushing. The melt enters the front mold plate 3 through the branch runner and then flows into the cavity through the injection port 13. The gate controls the flow rate and filling time of the melt to ensure uniform filling of the cavity. The branch runner design makes the plastic melt evenly distributed to each molding area and avoids local material shortage.

[0029] In this embodiment, as Figure 4 As shown, a partition 15 is provided on the top surface of the lower fixed plate 2 to form the active space of the core pulling mechanism 7. The partition 15 on the lower fixed plate 2 forms a closed space with other mold components, providing an active area for the ejector plate 10, push plate 11 and other components of the core pulling mechanism 7, ensuring that the ejection and resetting actions are not interfered with, preventing mechanical interference between the core pulling mechanism 7 and other mold components, and ensuring smooth operation.

[0030] In this embodiment, as Figure 4As shown, several support columns 16 are provided between the upper fixed plate 1 and the lower fixed plate 2. The support columns 16 are evenly distributed between the upper fixed plate 1 and the lower fixed plate 2 to bear the vertical pressure on the mold during the injection process, maintain the stable distance between the upper and lower fixed plates 2, prevent the upper and lower fixed plates 2 from deforming due to the injection pressure, and avoid flash or dimensional deviation caused by the mold not closing tightly.

[0031] Working principle: During use, the front mold plate 3 and the rear mold plate 4 are aligned under the sliding cooperation of the guide rod 5 and the guide sleeve 8. At the same time, the positioning ring cooperates with the positioning hole of the rear mold plate 4 to ensure that the concave molds of the front and rear mold plates 4 are accurately aligned to form a complete walkie-talkie base cavity. The injection molding machine injects molten plastic through the injection port 13 on the top surface of the upper fixed plate 1. The molten plastic passes through the main runner bushing, branch runner and gate in the runner plate 14. The branch runner is located in the front mold plate 3. Finally, the molten plastic is delivered to the concave molds of the front and rear mold plates 4 to fill and form the outer surface contour of the walkie-talkie base. After the mold is opened, the core pulling mechanism 7 is activated: the ejector plate 10 passes through the moving rear mold plate 4 and cooperates with the punch. The push plate 11 fixes the ejector plate 10. The ejector plate 10 is pushed by external force to push the solidified walkie-talkie base out of the punch.

[0032] The above are merely preferred embodiments of this application and are not intended to limit this application. Although this application has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this application should be included within the protection scope of this application.
