Description

Technical Field

[0001] The utility model relates to the technical field of aluminum profile molds, in particular to a vacuum aluminum profile mold. Background Art

[0002] Aluminum profile molds have excellent thermal conductivity, which is higher than that of general die steels. Therefore, the cold cutting time during the production of the molds can be saved, thereby improving the production efficiency of the molds.

[0003] In the invention patent application with the publication number of CN109228169A, a vacuum aluminum profile mold is disclosed, which includes an upper template, an upper cavity, a limiting groove, a mounting post, an outer turntable, a handle, a fixed sleeve, a limiting head, a lower template, a lower cavity, an air extraction port, a mounting hole, a fixed groove, a ejector rod, a first rubber plate, a connecting rod, an air suction mechanism, a gas one-way valve, a suction pipe and a second rubber plate.

[0004] Although the existing aluminum profile molds can ensure the vacuum inside the molds by means of a needle extraction method, the sealing performance between the molds is insufficient, and air is still likely to enter, affecting the stability of the vacuum state. Summary of the Utility Model

[0005] The purpose of the utility model is to solve the shortcoming of the unstable vacuum state of the existing vacuum aluminum profile molds, and to propose a vacuum aluminum profile mold.

[0006] In order to achieve the above purpose, the utility model adopts the following technical scheme:

[0007] A vacuum aluminum profile mold includes a lower mold and an upper mold. The lower mold and the upper mold are in contact with each other. A runner is arranged on the upper mold. A sealing ring is embedded at the upper end of the lower mold, and the sealing ring is in contact with the upper mold. A bracket is fixedly connected to the front surface of the lower mold. A cylinder is fixedly installed on the vertical part of the bracket. The piston rod of the cylinder penetrates through the bracket and is slidably connected to the bracket. The end of the piston rod is fixedly connected to a linkage plate. Two push frames are fixedly connected to the side of the linkage plate close to the lower mold. The middle part of the upper end of the push frame is fixedly connected to an L-shaped frame. Slide sleeves are fixedly connected to both the left and right sides of the lower mold. The push frame is slidably connected to the slide sleeve. Fixed blocks are fixedly connected to both the left and right sides of the upper mold. The L-shaped frame is slidably connected to the fixed block.

[0008] In addition, a preferred structure is that an air pipe is arranged on the upper mold, and a one-way valve is arranged on the air pipe. Through the arrangement of the air pipe, the inside of the lower mold and the upper mold can be evacuated by means of an air extraction mechanism.

[0009] In addition, a preferred structure is that a limiting block is fixedly connected to the end of the push frame, and the limiting block is an integral structure with the push frame. Through the arrangement of the limiting block, the push frame is limited in terms of its stroke.

[0010] In addition, a preferred structure is that a bevel is provided at the bottom end of the L-shaped frame. Through the provision of the bevel, when the L-shaped frame interacts with the fixed block, the fixed block can be subjected to a downward thrust.

[0011] In addition, a preferred structure is that a latch is slidably connected inside the push frame, and the latch is engaged with the sliding sleeve, and a spring is provided inside the push frame. Through the provision of the latch, in cooperation with the sliding sleeve, it has a positioning effect on the sliding position of the push frame.

[0012] In addition, a preferred structure is that one end of the spring is fixedly connected to the latch, and the other end of the spring is fixedly connected to the inner surface of the push frame. Through the provision of the spring, the elastic force can act on the latch.

[0013] The beneficial effects of the present utility model are as follows: By providing a sealing ring on the lower mold, then providing two push frames pushed by a cylinder on the lower mold, and an L-shaped frame is provided on the push frame. In this way, during the lateral movement of the L-shaped frame, the L-shaped frame interacts with two fixed blocks on the upper mold, making the combination of the lower mold and the upper mold tighter. In this way, after evacuating the space between the molds, it is not easy to leak air, ensuring the stability of the vacuum state. BRIEF DESCRIPTION OF THE DRAWINGS

[0019] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments.

[0020] Referring to Figures 1-4 , a vacuum aluminum profile mold includes a lower mold 1 and an upper mold 2. The lower mold 1 and the upper mold 2 are in contact with each other. A runner 3 is provided on the upper mold 2, and an air pipe 4 is provided on the upper mold 2, and a one-way valve is provided on the air pipe 4. Through the setting of the air pipe 4, a pumping mechanism can be used to evacuate the inside of the lower mold 1 and the upper mold 2. A sealing ring 5 is embedded at the upper end of the lower mold 1, and the sealing ring 5 is in contact with the upper mold 2.

[0021] Referring to Figures 1-4 , a bracket 6 is fixedly connected to the front surface of the lower mold 1. A cylinder 7 is fixedly installed on the vertical portion of the bracket 6. The piston rod of the cylinder 7 penetrates through the bracket 6 and is slidably connected to the bracket 6. The end of the piston rod is fixedly connected to a linkage plate 8. Two push frames 9 are fixedly connected to the side of the linkage plate 8 close to the lower mold 1. A middle portion of the upper end of the push frame 9 is fixedly connected to an L-shaped frame 11. Slide sleeves 10 are fixedly connected to both the left and right sides of the lower mold 1. The push frame 9 is slidably connected to the slide sleeve 10. Fixed blocks 12 are fixedly connected to both the left and right sides of the upper mold 2. The L-shaped frame 11 is slidably connected to the fixed block 12.

[0022] Referring to Figures 1-4 , a limit block 13 is fixedly connected to the end of the push frame 9, and the limit block 13 is an integral structure with the push frame 9. Through the setting of the limit block 13, it has a limit effect on the stroke of the push frame 9. An inclined surface is provided at the bottom of the end of the L-shaped frame 11. Through the setting of the inclined surface, when the L-shaped frame 11 interacts with the fixed block 12, the fixed block 12 can be subjected to a downward thrust. A pin 14 is slidably connected inside the push frame 9, and the pin 14 is clamped with the slide sleeve 10. A spring 15 is provided inside the push frame 9. Through the setting of the pin 14, in cooperation with the slide sleeve 10, it has a positioning effect on the sliding position of the push frame 9. One end of the spring 15 is fixedly connected to the pin 14, and the other end of the spring 15 is fixedly connected to the inner surface of the push frame 9. Through the setting of the spring 15, elastic force can act on the pin 14.

[0023] The specific implementation process of the present invention is as follows: When in use, after the lower mold 1 and the upper mold 2 are closed, the linkage plate 8 is pushed by the cylinder 7. The linkage plate 8 simultaneously pushes the two push frames 9 to move. The push frames 9 drive the L-shaped frames 11 to move synchronously under the guidance of the slide sleeves 10. Subsequently, the L-shaped frames 11 come into contact with the fixed blocks 12 on the upper mold 2 and exert forces on each other, thereby enabling the lower mold 1 and the upper mold 2 to be stressed with each other, and then compressing the sealing ring 5. In this way, after the air in the mold is discharged through the air pipe 4, the outside air is not easily infiltrated, ensuring the stability of the vacuum state.

[0024] The above are only the preferred specific embodiments of the present utility model, but the protection scope of the present utility model is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present utility model, according to the technical solution and the inventive concept of the present utility model, making equivalent substitutions or changes should be covered within the protection scope of the present utility model.
