[0001] The utility model relates to the technical field of recycling bin production, in particular to an injection mold provided with a guiding mechanism. Background Technique

[0002] A recycling bin is a container specifically used for collecting recyclable waste, which plays an important role in environmental protection and resource recycling. During the production of recycling bins, an injection mold is required to inject and form the air inlet joint of the recycling bin.

[0003] When the existing injection mold injects and forms the air inlet joint of the recycling bin, since the air inlet joint is in a bent tube shape, during the forming process, a core is also required to fill the inside of the pipe, and after the forming, an additional power source is needed to take out the core inside the air inlet joint, resulting in the problem of increasing the equipment usage cost.

[0004] Therefore, in view of this, research and improvement are carried out on the existing structure and deficiencies, and an injection mold provided with a guiding mechanism is provided. Content of the Utility Model

[0005] The purpose of the utility model is to provide an injection mold provided with a guiding mechanism to solve the problems raised in the above background technique.

[0006] To achieve the above purpose, the utility model provides the following technical solution: an injection mold provided with a guiding mechanism, including a top plate and a guiding component. The bottom of the top plate is connected with an upper template, and a lower template is arranged at the bottom of the upper template. The guiding component is arranged between the upper template and the lower template. The guiding component includes a guiding rod, a slider, a sliding groove, a limiting plate and a core. The middle outer side of the guiding rod is slidably connected with the slider. The outer end of the top of the lower template is provided with a sliding groove, and limiting plates are arranged at the lower ends of both sides of the sliding groove. One end of the slider is connected with the core.

[0007] Further, the guiding rod is inclined and is fixedly connected with the upper template.

[0008] Further, the lower part of the slider is in an inverted T shape and is slidably connected with the limiting plate.

[0009] Further, an upper mold core is fixed inside the upper template, and a lower mold core is connected to the bottom of the upper mold core.

[0010] Further, a base is arranged at the outer end of the bottom of the lower template, and sliding sleeves are arranged inside the four ends of the lower template. A guiding column is slidably connected inside the sliding sleeve, and the guiding column is fixedly connected with the top plate.

[0011] Furthermore, a demolding assembly is provided on the top of the base. The demolding assembly includes a driving plate, ejector pins, and a panel. A ejector pin is provided in the middle of the top surface of the driving plate, and a panel is provided on the outer side of the lower end of the ejector pin, and the panel is fixedly connected to the driving plate.

[0012] Furthermore, the demolding assembly further includes slide rods and springs. Four ends of the top of the driving plate are fixed with slide rods, and springs are sleeved on the outer sides of the lower ends of the slide rods.

[0013] Furthermore, the slide rods are slidably connected to the lower template, and the lower template is fixedly connected to the lower mold core.

[0014] The utility model provides an injection mold provided with a guiding mechanism, which has the following beneficial effects:

[0015] 1. Through the arrangement of the guiding component, the utility model can use the chute and the limiting plate to limit the moving direction of the slider. At the same time, the guiding rod is inclined. Therefore, during the mold closing process, the guiding rod will push the slider, so that it drives the mold core to move towards the center. And during the mold opening process, as the upper template moves upward, the guiding rod can push the slider, so that it drives all the mold cores to move outward and automatically separate from the injection molded part, without using an additional power source to drive the position of a single slider, thereby saving the overall use cost. At the same time, the sliding sleeve is used to limit the guiding column during the movement, so that the upper template can only move vertically upward, thereby avoiding the horizontal skew of the guiding rod during the movement and affecting the position of the slider after the movement;

[0016] 2. Through the arrangement of the demolding assembly, after the upper template is opened, when the air inlet joint of the recovery barrel needs to be taken out, the driving plate is driven to move upward by an external power device, and the ejector pin can eject the air inlet joint from the lower mold core, thereby improving the convenience during part taking. And multiple ejector pins are provided, which can make the force uniform, thereby improving the demolding effect. And the slide rod is also used to guide the moving position of the driving plate, further improving the stability during its movement. BRIEF DESCRIPTION OF THE DRAWINGS

Specific embodiments

[0023] The following further describes in detail the embodiments of the present utility model in conjunction with the drawings and embodiments. The following embodiments are used to illustrate the present utility model, but cannot be used to limit the scope of the present utility model.

[0024] As Figures 1 to 5 As shown in the figure, an injection mold with a guiding mechanism includes a top plate 1 and a guiding assembly 10. The bottom of the top plate 1 is connected to an upper template 2, and a lower template 3 is provided at the bottom of the upper template 2. An upper mold core 4 is fixed inside the upper template 2, and a lower mold core 5 is connected to the bottom of the upper mold core 4. A base 6 is arranged at the outer end of the bottom of the lower template 3, and sliding sleeves 7 are arranged inside the four ends of the lower template 3. A guiding column 8 is slidably connected inside the sliding sleeve 7, and the guiding column 8 is fixed to the top plate 1. The guiding column 8 is used to limit the direction when the upper template 2 moves. A demoulding assembly 9 is arranged on the top of the base 6. The demoulding assembly 9 includes a driving plate 901, an ejector pin 902 and a panel 903. An ejector pin 902 is arranged in the middle of the top surface of the driving plate 901, and a panel 903 is arranged outside the lower end of the ejector pin 902, and the panel 903 is fixed to the driving plate 901. By driving the driving plate 901 to move upward by an external power device, the ejector pin 902 can eject the air inlet joint from the lower mold core 5, thereby improving the convenience during part taking. And a plurality of ejector pins 902 are provided, which can make the force uniform, thereby improving the demoulding effect. The demoulding assembly 9 further includes a sliding rod 904 and a spring 905. The four ends of the top of the driving plate 901 are fixed with sliding rods 904, and a spring 905 is sleeved outside the lower end of the sliding rod 904. The sliding rod 904 is slidably connected to the lower template 3, and the lower template 3 is fixed to the lower mold core 5. The sliding rod 904 is used to guide the moving position of the driving plate 901, further improving the stability during its movement.

[0025] As Figures 2 to 4As shown, the guiding assembly 10 is arranged between the upper template 2 and the lower template 3. The guiding assembly 10 includes a guiding rod 1001, a slider 1002, a chute 1003, a limiting plate 1004 and a die core 1005. The outer side of the middle part of the guiding rod 1001 is slidably connected with the slider 1002. The guiding rod 1001 is inclined and fixedly connected with the upper template 2. Due to the inclination of the guiding rod 1001, during the process of mold closing or mold opening, the guiding rod 1001 will drive the slider 1002 to move. A chute 1003 is opened at the outer end of the top of the lower template 3, and limiting plates 1004 are arranged at the lower ends of both sides of the chute 1003. The lower part of the slider 1002 is in an inverted T shape and is slidably connected with the limiting plate 1004. The chute 1003 and the limiting plate 1004 are used to limit the moving direction of the slider 1002. One end of the slider 1002 is connected with a die core 1005. During the process of mold closing, the slider 1002 will drive the die core 1005 to move towards the center. During the process of mold opening, as the upper template 2 moves upward, the guiding rod 1001 can push the slider 1002, so that it drives all the die cores 1005 to move outward and automatically separate from the injection molded part.

[0026] In summary, for the injection mold provided with the guiding mechanism, during use, first, according to Figures 1 to 5 the structure shown in the figure, first use an external device to close the upper template 2 and the lower template 3. During this process, the chute 1003 and the limiting plate 1004 can be used to limit the moving direction of the slider 1002. At the same time, the guiding rod 1001 is inclined. Therefore, during the process of mold closing, the guiding rod 1001 will push the slider 1002 to drive the die core 1005 to move towards the center. Then, use an injection molding machine to inject between the upper mold core 4 and the lower mold core 5 through the runner inside the top plate 1. After the injection is completed, the external device will separate the upper template 2 from the lower template 3. At this time, as the upper template 2 moves, the guiding rod 1001 can push the slider 1002, so that it drives all the die cores 1005 to move outward and automatically separate from the injection molded part. At the same time, the sliding sleeve 7 is used to limit the guiding column 8, so as to prevent the guiding rod 1001 from tilting during movement and affecting the position of the slider 1002 after movement. Finally, drive the driving plate 901 to move upward through an external power device, and the ejector pin 902 can eject the air inlet joint from the lower mold core 5, thereby improving the convenience during part taking. And multiple ejector pins 902 are provided, which can make the force uniform. In addition, the sliding rod 904 is used to guide the moving position of the driving plate 901, further improving the stability during its movement.
