Description

Technical Field

[0001] This utility model relates to the field of injection mold technology, and in particular to an injection mold for the inner shell of a label printer flip cover. Background Technology

[0002] Injection molds are precision tools used for the mass production of plastic products. They are typically made of high-hardness steel and include core components such as cavities, gating systems, cooling systems, and ejection mechanisms. Their working principle involves injecting molten plastic at high temperatures into the mold cavity, which then cools and solidifies before demolding. Injection molds can efficiently manufacture plastic parts with complex shapes and precise dimensions, such as electronic device housings, automotive parts, or home appliance components, and are widely used in modern industrial fields.

[0003] The existing label printer flip-top inner shell also requires injection molding during the manufacturing process. Due to the complex structure of the flip-top inner shell, the following defects may occur during the injection molding process:

[0004] 1. Obstruction of the plastic melt flow path results in insufficient filling or obvious bond lines, affecting strength;

[0005] 2. Differences in cooling and shrinkage can cause shrinkage marks, warping, and even dimensional deviations, which in turn affect the assembly accuracy of the shell and internal components.

[0006] Therefore, it is urgent to research and develop an injection mold for the inner shell of a label printer flip cover to solve the above-mentioned technical problems. Summary of the Invention

[0007] The purpose of this utility model is to provide an injection mold for the inner shell of a label printer flip cover, which can improve the structural strength and product precision of the injection molded product.

[0008] To achieve the above objectives, this utility model provides an injection mold for the inner shell of a label printer flip cover, the specific implementation of which is as follows:

[0009] A label printer flip cover inner shell injection mold includes a fixed mold fixing plate and a moving mold fixing plate. A fixed template is fixed in the fixed mold fixing plate, and a moving template is fixed in the moving mold fixing plate. The moving template and the fixed template are assembled and matched to form a core cavity for injection molding.

[0010] A first forming surface is provided on the fixed template, and a second forming surface is provided on the moving template. A plurality of exhaust channels are provided on the first forming surface. When the fixed template and the moving template are assembled, there is an exhaust gap between the exhaust channels and the second forming surface.

[0011] A first cooling pipe is provided on the fixed mold fixing plate, which surrounds the periphery of the first molding surface. Two second cooling pipes are provided on the moving mold fixing plate, which are arranged opposite each other and located on both sides of the second molding surface.

[0012] This utility model discloses an injection mold for a flip-top inner shell of a label printer. Compared with the prior art, it sets several venting channels on the first molding surface of the fixed mold plate. When the fixed mold plate and the moving mold plate are assembled, there is a venting gap between the venting channels and the second molding surface. On the one hand, the venting gap is used to discharge the gas trapped in the core cavity, reducing porosity, scorching, or filling defects on the injection molded product, ensuring the surface smoothness and internal structural integrity of the injection molded product. On the other hand, it reduces gas resistance, allowing the plastic melt to fill the cavity more smoothly, reducing the risk of short shots, and further ensuring the complete molding of the product. By setting a first cooling pipe around the periphery of the first molding surface on the fixed mold plate and two second cooling pipes located on both sides of the second molding surface on the moving mold plate, uniform cooling is achieved during the injection molding of the core cavity, avoiding shrinkage marks, warping, or even dimensional deviations, which could affect the assembly accuracy of the shell and internal components.

[0013] In some embodiments, a mold fixing groove is provided on the fixed mold fixing plate, the fixed template is fixed in the fixed mold fixing groove, a first channel is opened in the fixed template, the first channel surrounds the periphery of the first molding surface, and the first cooling pipe is provided in the first channel.

[0014] By using a first channel to fix the first cooling pipe, the installation stability of the first cooling pipe is improved.

[0015] In some embodiments, two first through holes are provided on the outer wall of the fixed mold fixing plate to guide the fixed mold fixing groove. The inlet of the first cooling pipe passes through either of the first through holes, and the outlet of the first cooling pipe passes through the other first through hole.

[0016] The first through hole allows the inlet and outlet of the first cooling pipe to be connected to the outside, ensuring a stable flow of coolant into and out of the first cooling pipe.

[0017] In some embodiments, a moving mold fixing groove is provided on the moving mold fixing plate, the moving mold plate is fixed in the moving mold fixing groove, a second channel is opened in the moving mold plate, the second channel is located on both sides of the second molding surface, and a second cooling pipe is provided in both second channels.

[0018] The installation stability of the second cooling pipe is improved by using a second channel to fix the second cooling pipe.

[0019] In some embodiments, two second through holes and two third through holes are provided on the outer wall of the moving mold fixing plate to guide the moving mold fixing groove. The inlet of the second cooling pipe passes through any of the second through holes, and the outlet passes through the third through hole on the same side as the second through hole. The inlet of the other second cooling pipe passes through the other second through hole, and the outlet passes through the other third through hole.

[0020] The inlet and outlet of the two sets of second cooling pipes are connected to the outside through the second and third through holes, ensuring that the coolant can stably enter and exit the second cooling pipes.

[0021] In some embodiments, the exhaust channel includes an air intake section, a concentrating section, and an exhaust section. The air intake section is provided in a plurality of parts. One end of the air intake section is connected to the edge of the first forming surface, and the other end is connected to the same concentrating section. One end of the exhaust section is connected to the concentrating section, and the other end extends to the edge of the fixed template.

[0022] By setting the exhaust channel to include an air intake section, a concentrator section, and an exhaust section, the gas generated in the core cavity during injection molding is discharged sequentially through the air intake section, the concentrator section, and the exhaust section, which improves the flow of plastic melt, enhances the filling effect, and avoids the occurrence of air holes, scorching, or filling defects due to poor exhaust.

[0023] In some embodiments, a mold top plate is provided on the top of the moving mold fixing plate, and an injection molded part is provided on the mold top plate. The top of the injection molded part cooperates with an external injection molding machine, and the bottom of the injection molded part extends through the mold top plate, the moving mold fixing plate, and the moving mold plate into the core cavity.

[0024] By setting the injection molded part on the top plate of the mold, the top of the injection molded part cooperates with the external injection molding machine, and the bottom extends through the top plate of the mold, the moving mold fixing plate and the moving template into the core cavity, ensuring that the injection molding machine and the mold are correctly matched for injection molding.

[0025] In some embodiments, a first fixing block is provided inside the moving mold fixing plate, and a first inclined rod is provided on the first fixing block. The other end of the first inclined rod passes through the moving mold fixing plate and the moving mold template and extends to the position of the second molding surface.

[0026] By setting the first inclined bar, the molding surface of the complex part of the product is set on the first inclined bar according to the situation of the injection molded product, thereby reducing the molding difficulty of the complex part.

[0027] In some embodiments, connecting square plates are provided on both sides of the bottom of the fixed mold plate, a mold base plate is provided at the bottom of the connecting square plates, an ejector pin base plate is provided at the top of the mold base plate between the two connecting square plates, an ejector pin top plate is provided at the top of the ejector pin base plate, and a plurality of ejector pins are provided on the ejector pin base plate. The ejector pins pass through the ejector pin top plate, the fixed mold plate, and the fixed mold plate to extend to the position of the first molding surface.

[0028] By setting ejector pins on the ejector base plate that pass through the ejector top plate, the fixed mold plate, and the fixed template and extend to the first molding surface, and setting the ejector pins with shapes that match the injection molded product, the difficulty of injection molding is reduced, and the injection molded product is ejected during demolding, thereby improving the demolding efficiency of the injection molded product.

[0029] In some embodiments, a second fixing block is provided on the top of the ejector plate, and a second inclined rod is provided on the second fixing block. The other end of the second inclined rod passes through the fixed mold fixing plate and the fixed mold plate and extends to the position of the first molding surface.

[0030] By setting the second inclined bar, the molding surface of the complex part of the product can be set on the second inclined bar according to the situation of the injection molded product, which further reduces the molding difficulty of the complex part.

[0031] Based on the above technical solution, this utility model has the following beneficial effects compared with the prior art:

[0032] By setting several venting channels on the first molding surface of the fixed mold plate, and creating a venting gap between the venting channels and the second molding surface when the fixed mold plate and the moving mold plate are assembled, the gas trapped in the core cavity is discharged through the venting gap, reducing porosity, scorching, or filling defects on the injection molded product, ensuring the surface smoothness and internal structural integrity of the injection molded product. On the other hand, it reduces gas resistance, allowing the plastic melt to fill the cavity more smoothly, reducing the risk of short shots, and further ensuring the complete molding of the product. By setting a first cooling pipe around the perimeter of the first molding surface on the fixed mold plate, and setting two second cooling pipes on both sides of the second molding surface on the moving mold plate, uniform cooling is achieved during injection molding of the core cavity, avoiding shrinkage marks, warping, or even dimensional deviations, which could affect the assembly accuracy of the shell and internal components.
