Description

Technical Field

[0001] This utility model relates to the field of injection mold technology, and in particular to a stackable printer cover production mold. Background Technology

[0002] Stacked mold technology is a cutting-edge mold technology that differs from ordinary injection molds. It involves overlapping multiple cavities in a single mold along the mold-closing direction. Such molds typically have multiple parting surfaces, each of which can accommodate one or more cavities. Simply put, stacked molds are equivalent to stacking multiple single-layer molds together and installing them on a single injection molding machine for injection molding production.

[0003] A search revealed Chinese Patent Publication No. CN211891767U, which discloses a stacked injection mold. This invention uses a drive motor to rotate a lead screw, which in turn drives each mold plate to begin mold closing. When one parting surface completes mold closing and reaches the torque limiter's limit value, the torque limiter idles, and the lead screw continues to drive the other mold plates to move, sequentially achieving mold closing of the other parting surfaces, thus completing the mold closing process. After injection molding and workpiece forming, the drive motor drives the lead screw to start mold opening. When one mold plate moves to the limit block and reaches the torque limiter's limit value, the torque limiter idles, and the lead screw continues to drive the other mold plates to move, sequentially achieving mold opening of the other parting surfaces, thus completing the mold opening process and removing the workpiece.

[0004] The aforementioned patented stacked mold requires the rotation of a lead screw in conjunction with a torque limiter to drive multiple molds one by one, whether closing or opening the mold. This results in multiple molds needing to open or close sequentially, making it impossible to close or open the stacked mold synchronously. Consequently, the closing and opening efficiency of the stacked mold is low, affecting product production efficiency. Therefore, a stackable printer cover production mold is proposed to solve the above problems. Summary of the Invention

[0005] To overcome the above shortcomings, this utility model provides a stackable printer cover production mold, which aims to solve the problem mentioned in the prior art that "the opening and closing efficiency of the stacking mold is low, which affects the product production efficiency".

[0006] To achieve the above objectives, the present invention adopts the following technical solution: a stackable printer cover plate production mold, including a fixed mold, guide rods fixedly connected to both the left and right sides of the fixed mold, an installation platform fixedly connected to the end of the guide rod away from the fixed mold, an injection mold slidably connected to the outer wall of the guide rod, a driving mechanism provided at the top of the fixed mold, and a demolding mechanism provided inside the injection mold; The drive mechanism includes a slide plate that is slidably connected to the top of the mounting platform. The slide plate has an inclined groove. A sliding shaft is fixedly connected to the top of the injection mold. A protruding plate is fixedly connected to the lower surface of the slide plate. An electric push rod is fixedly connected to the side wall of the mounting platform.

[0007] As a further description of the above technical solution: The demolding mechanism includes a slide rod, which is slidably connected to the inner wall of the injection mold. A push rod is fixedly connected to one side of the slide rod, and a spring is fixedly connected to the other side of the slide rod.

[0010] As a further description of the above technical solution: The push rod passes through and is slidably connected to the inner wall of the injection mold, and the end of the spring away from the slide rod is fixedly connected to the inner wall of the injection mold.

[0011] As a further description of the above technical solution: The injection mold is provided in six parts. The six injection molds are divided into two groups of three. The two groups of injection molds are mirror images of the fixed mold on the left and right sides of the fixed mold with the fixed mold as the central axis.

[0012] As a further description of the above technical solution: The inclined groove is provided in six places. The six inclined grooves are divided into three groups of two. Each group of inclined grooves is arranged in a figure-eight shape on the slide plate with the fixed mold as the central axis. The farther the inclined groove is from the fixed mold, the larger its included angle becomes.

[0013] As a further description of the above technical solution: The outer wall of the sliding shaft is attached to the inner wall of the inclined groove, and the output end of the electric push rod is fixedly connected to the side wall of the convex plate.

[0018] 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.

[0019] Reference Figure 1 - Figure 3 This utility model provides an embodiment of a stackable printer cover production mold, including a fixed mold 1. Guide rods 2 are fixedly connected to both the left and right sides of the fixed mold 1. The guide rods 2 can provide guidance for the injection mold 4. An mounting platform 3 is fixedly connected to the end of the guide rod 2 away from the fixed mold 1. In use, the mounting platform 3 needs to be installed on the injection molding machine with bolts. The outer wall of the guide rod 2 is slidably connected to the injection mold 4. There are six injection molds 4. Stacking the six injection molds 4 together can improve product production efficiency. The six injection molds 4 are divided into two groups of three. The two groups of injection molds 4 are mirror images of the fixed mold 1 on the left and right sides of the fixed mold 1 with the fixed mold 1 as the central axis. A drive mechanism 5 is provided on the top of the fixed mold 1. A demolding mechanism 6 is provided inside the injection mold 4.

[0020] Reference Figure 2 - Figure 3 The drive mechanism 5 includes a slide plate 51, which is slidably connected to the top of the mounting platform 3. Six inclined grooves 52 are provided on the slide plate 51, corresponding to six injection molds 4. The six inclined grooves 52 are divided into three groups of two, and each group of inclined grooves 52 is arranged in a figure-eight shape on the slide plate 51 with the fixed mold 1 as the central axis. The farther the inclined groove 52 is from the fixed mold 1, the larger the angle between the inclined groove 52 and the fixed mold 1. Since the angles between the three groups of inclined grooves 52 and the fixed mold 1 are different, the slide plate 51 slides within a fixed stroke. The larger the angle of the inclined groove 52, the longer the distance that it pushes the sliding shaft 53. Therefore, the six injection molds 4 guide... When the outer wall of rod 2 slides, the injection mold 4 that is farther away from the fixed mold 1 slides faster and farther, so that the six injection molds 4 can open or close synchronously. The top of the injection mold 4 is fixedly connected to a sliding shaft 53. The outer wall of the sliding shaft 53 is attached to the inner wall of the inclined groove 52. When the slide plate 51 slides, the inclined groove 52 will push the sliding shaft 53, so that the injection mold 4 slides on the outer wall of the guide rod 2. The lower surface of the slide plate 51 is fixedly connected to a protruding plate 54. The side wall of the mounting platform 3 is fixedly connected to an electric push rod 55. The output end of the electric push rod 55 is fixedly connected to the side wall of the protruding plate 54. Activating the electric push rod 55 in conjunction with the protruding plate 54 can drive the slide plate 51 to slide on the top of the mounting platform 3.

[0021] Reference Figure 2 , Figure 4 and Figure 5 The demolding mechanism 6 includes a slide rod 61, which is slidably connected to the inner wall of the injection mold 4. A push rod 62 is fixedly connected to one side of the slide rod 61, penetrating and slidably connected to the inner wall of the injection mold 4. Through the sliding action of the slide rod 61 in conjunction with the push rod 62, the product inside the injection mold 4 can be ejected, thus automatically completing demolding. A spring 63 is fixedly connected to the other side of the slide rod 61, with the end of the spring 63 away from the slide rod 61 fixedly connected to the inner wall of the injection mold 4. The elasticity of the spring 63 can cause the slide rod 61 to slide and reset within the inner wall of the injection mold 4. The top of the injection mold 4 is through... Furthermore, a slider 64 is rotatably connected. The bottom of the slider 64 has a first inclined surface 65. The outer wall of the first inclined surface 65 is attached to the outer wall of the slide rod 61. As the slider 64 slides into the injection mold 4, the first inclined surface 65 at the bottom of the slider 64 will squeeze the slide rod 61, causing the slide rod 61 to slide laterally on the inner wall of the injection mold 4 and stretch the spring 63. The top of the slider 64 has a second inclined surface 66. When the slide plate 51 slides on the top of the mounting platform 3 and contacts the second inclined surface 66 at the top of the slider 64, the slide plate 51 will squeeze the second inclined surface 66, causing the slider 64 to slide into the injection mold 4.

[0022] Working principle: When mold opening is required, the electric push rod 55 is activated to push the convex plate 54, which in turn pushes the slide plate 51. At this time, the slide plate 51 slides on the top of the mounting platform 3 and gradually approaches the slider 64. During the sliding process, the three sets of inclined grooves 52 with different included angles push the sliding shaft 53, which in turn pushes the injection mold 4. At this time, the six injection molds 4 slide on the outer wall of the guide rod 2 and gradually move away from the fixed mold 1, so that the six injection molds 4 can open synchronously and improve the demolding efficiency of the injection molds 4.

[0023] When mold closing is required, the electric push rod 55 is activated to pull the convex plate 54, which in turn pulls the slide plate 51. At this time, the slide plate 51 slides on the top of the mounting platform 3 and gradually moves away from the slider 64. During the sliding process, the three sets of inclined grooves 52 with different included angles push the sliding shaft 53, which in turn pushes the injection mold 4. This allows the six injection molds 4 to slide on the outer wall of the guide rod 2 and gradually approach the fixed mold 1, thereby enabling the six injection molds 4 to close synchronously and improve injection efficiency.

[0024] When the sliding plate 51 slides on the top of the mounting platform 3 and contacts the inclined surface 66 on the top of the slider 64, the sliding plate 51 will squeeze the inclined surface 66, causing the slider 64 to slide into the injection mold 4. At the same time, the inclined surface 65 at the bottom of the slider 64 will squeeze the slide rod 61, causing the slide rod 61 to slide laterally on the inner wall of the injection mold 4 and stretch the spring 63. Simultaneously, the slide rod 61 will push the ejector rod 62, causing the ejector rod 62 to slide on the inner wall of the fixed mold 1 and protrude from the fixed mold 1. At this time, the protruding ejector rod 62 can be used to eject the product inside the injection mold 4, causing the product to fall downward under its own gravity. Thus, demolding can be automatically completed after the mold is opened, further improving demolding efficiency and greatly improving product production efficiency.

[0025] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model 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 the present utility model should be included within the protection scope of the present utility model.
