Description

Technical Field

[0001] This utility model belongs to the field of plastic processing technology, specifically relating to an injection molding machine for processing plugs. Background Technology

[0002] The main function of an injection molding machine for plug processing is to manufacture plastic plugs through injection molding technology. The injection molding machine can complete the entire process from heating and melting the raw material, injecting it into the mold, cooling and shaping it to removing the finished product in a short time. It is suitable for large-scale production and rapid manufacturing needs. By precisely controlling key parameters such as temperature, pressure, speed and time, the injection molding machine can ensure that the produced plugs have good surface finish, accurate dimensions and consistent quality.

[0003] In the existing technology, some injection molds for injection molding machines used for plug processing are usually fixed with screws. Each time the mold is changed, it may take a long time to disassemble and reassemble. For production lines that need to change molds frequently, the long mold change time may become a production bottleneck, which directly affects the overall production efficiency. Moreover, the complicated disassembly and reassembly process may lead to increased wear and tear on the mold or injection molding machine parts, or even damage, which not only increases the cost of maintenance and replacement, but may also affect the consistency and stability of product quality.

[0025] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Those skilled in the art can make similar extensions without departing from the spirit of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0026] Secondly, the term "an embodiment" or "embodiment" as used herein refers to a specific feature, structure, or characteristic that may be included in at least one implementation of the present invention. The phrase "in one embodiment" appearing in different places in this specification does not necessarily refer to the same embodiment, nor is it a single or selective embodiment that excludes other embodiments.

[0027] Example

[0028] Reference Figures 1 to 7 This embodiment of the present invention provides an injection molding machine for processing plugs, which can achieve the effect of quickly disassembling and assembling injection molds without the use of professional disassembly and assembly tools, thereby greatly improving the working efficiency of production lines that require frequent mold changes.

[0029] The injection molding machine body 100 includes a frame 101, a material tank 102 disposed above the frame 101, an injection plate 103 fixedly connected to the top of the frame 101 and used in conjunction with the material tank 102, and an extrusion assembly 104 disposed on the side of the injection plate 103 away from the material tank 102.

[0030] It should be noted that the material tank 102 is used to load the injection molding compound and is capable of delivering the injection molding compound into the injection molding plate 103.

[0031] The splicing mechanism 200 includes a toothed disc 201, arc-shaped grooves 202 respectively opened on both sides of the toothed disc 201, a drive column 203 slidably connected to the inner surface of the arc-shaped grooves 202, a connecting plate 204 fixedly connected to the outer surface of the drive column 203, a driven column 205 fixedly connected to one end of the connecting plate 204 away from the drive column 203, a positioning clamp 206 fixedly connected to the other end of the driven column 205, a limiting frame 207 fixedly connected to the outside of the extrusion assembly 104 and used in conjunction with the connecting plate 204, a drive assembly 208 for driving the toothed disc 201 to rotate, and a limiting assembly 209 for limiting the drive assembly 208.

[0032] It should be noted that by limiting the connecting plate 204 through the limiting frame 207, the connecting plate 204 limits the driving column 203, so that when the gear plate 201 drives the arc grooves 202 on both sides to rotate, the two arc grooves 202 can respectively drive the two driving columns 203 to move towards each other. The positioning fixture 206 is used to support the injection mold, the driving component 208 is used to control the rotation of the gear plate 201, and the limiting component 209 is used to limit the driving component 208.

[0033] Specifically, the extrusion assembly 104 includes a pneumatic push rod 104a adapted to be installed inside the frame 101, a support plate 104b fixedly sleeved on the outer surface of the pneumatic push rod 104a, and a limiting post 104c fixedly connected to the inner wall of the frame 101 and used in conjunction with the support plate 104b.

[0034] It should also be noted that the drive push rod 104a is used to drive the support plate 104b to move linearly with the injection mold. When the injection mold moves to the position where it contacts the injection plate 103, the operator can control the flow of the injection plastic inside the injection plate 103 to the surface of the injection mold, thereby forming the plug.

[0035] Furthermore, the inner surface of the support plate 104b slides in contact with the outer surface of the limiting post 104c, and the gear disc 201 is rotatably sleeved on the outer surface of the support plate 104b.

[0036] Preferably, the outer surface of the driven column 205 slides in contact with the inner wall of the groove of the support plate 104b, the outer surface of the connecting plate 204 slides in contact with the inner surface of the limiting frame 207, and the outer surface of the limiting frame 207 is fixedly connected to the outer surface of the support plate 104b.

[0037] It should be noted that the drive assembly 208 includes a support block 208a fixedly connected to the outer surface of the support plate 104b, a connecting shaft 208b fixedly installed on the inner wall of the support block 208a via a bearing sleeve, a first bevel gear 208c fixedly sleeved on the connecting shaft 208b near the end of the gear disk 201, a second bevel gear 208d meshing with the outer surface of the first bevel gear 208c, a support shaft 208e fixedly connected to the inner surface of the second bevel gear 208d, a spur gear 208f fixedly sleeved on the outer surface of the support shaft 208e and used in conjunction with the gear disk 201, and a handwheel 208g fixedly connected to the end of the connecting shaft 208b away from the first bevel gear 208c.

[0038] The handwheel 208g can drive the connecting shaft 208b and the first bevel gear 208c to rotate synchronously, so that the first bevel gear 208c drives the second bevel gear 208d to rotate and the support shaft 208e to rotate. Then, the support shaft 208e drives the spur gear 208f to rotate synchronously, and the spur gear 208f drives the gear disk 201 to rotate.

[0039] Furthermore, the outer end face of the support shaft 208e is fixedly mounted on the outer surface of the support plate 104b by a bearing, and the teeth of the spur gear 208f mesh with the teeth of the gear disk 201.

[0040] Specifically, the limiting component 209 includes friction blocks 209a fixedly mounted on the outer surfaces of both sides of the support block 208a via bearings, springs 209b fixedly mounted on the inner side of the friction blocks 209a, and friction plates 209c fixedly sleeved on the outer surface of the connecting shaft 208b and used in conjunction with the springs 209b.

[0041] It should be explained that when the friction block 209a contacts the friction plate 209c, it can generate a strong frictional force, thereby limiting the connection shaft 208b.

[0042] In use, press both friction blocks 209a simultaneously to move both friction blocks 209a to the position where they are disengaged from the friction plate 209c, and apply pressure to the spring 209b. Turn the handwheel 208g to drive the connecting shaft 208b to rotate synchronously with the first bevel gear 208c. The first bevel gear 208c drives the second bevel gear 208d to rotate and rotate with the support shaft 208e. Then, the support shaft 208e drives the spur gear 208f to rotate synchronously, and the spur gear 208f drives the gear disk 201 to rotate.

[0043] The injection mold is placed at the center of the two positioning fixtures 206: the limiting frame 207 limits the connecting plate 204, so that the connecting plate 204 limits the drive column 203, so that when the gear plate 201 drives the arc grooves 202 on both sides to rotate, the two arc grooves 202 respectively drive the two drive columns 203, the connecting plate 204, the driven column 205 and the positioning fixtures 206 to move towards each other, so that the two positioning fixtures 206 clamp the injection mold.

[0044] After clamping the injection mold: simultaneously release the two friction blocks 209a, so that the two friction blocks 209a are reset by the reaction force of 209b and come into contact with the outer surface of the friction plate 209c to generate a strong friction force, thereby limiting the connecting shaft 208b and preventing the injection mold from falling off.

[0045] In summary, the drive component 208 can drive the splicing mechanism 200, enabling quick assembly and disassembly of the injection mold without the use of professional disassembly tools. This significantly shortens mold changeover time and reduces production line downtime, thereby improving overall production efficiency. The cooperation of the components in the limit component 209 can limit the drive component 208, preventing the fixed injection mold from falling off.
