Abstract
Description
Technical Field
[0001] This utility model relates to the field of aluminum profile mold technology, specifically to an aluminum profile extrusion mold assembly with pressure compensation function. Background Technology
[0002] Aluminum profile extrusion molds are tools used to manufacture aluminum profiles. They extrude aluminum alloy materials to process them into aluminum profile products of various shapes and sizes. Typically, aluminum profile extrusion molds consist of push rods, extrusion cylinders, and extrusion heads. The die head is the most important part, determining the cross-sectional shape of the aluminum profile, while the die opening guides the aluminum material into the mold. Aluminum profile extrusion molds need to possess high hardness, wear resistance, and corrosion resistance. Aluminum profile extrusion molds are widely used in construction, transportation, electronics, home decoration, and other fields.
[0003] However, existing molds are prone to wear after prolonged use, and fluctuating pressure changes are likely to occur during aluminum profile extrusion, which can easily lead to defects on the surface of the aluminum profile. Utility Model Content
[0004] The purpose of this invention is to provide an aluminum profile extrusion die assembly with pressure compensation function to solve the problems mentioned in the background art.
[0005] To achieve the above objectives, this utility model provides the following technical solution: an aluminum profile extrusion die assembly with pressure compensation function, comprising a punch die and an adjustment assembly. A concave die is provided on the right side of the punch die, and the pressure compensation adjustable adjustment assembly is provided on the left side of the punch die. The adjustment assembly includes a drain sleeve, an adjustment groove, an adjustment block, a micro hydraulic rod, and a fixing plate. An adjustment groove is provided on the inner wall surface of the drain sleeve, and an adjustment block is provided inside the adjustment groove. A micro hydraulic rod is installed on the side of the adjustment block, and the fixed end of the micro hydraulic rod is connected to the fixing plate. An extrusion feeding cylinder is connected to the left side of the drain sleeve.
[0006] Furthermore, the drainage sleeve and the adjustment groove are an integrated structure, and two adjustment blocks are symmetrically arranged about the vertical central axis of the drainage sleeve.
[0007] Furthermore, a feed sleeve is provided on the right side of the concave mold, and a fixing frame is installed on the outside of the concave mold.
[0008] Furthermore, a connecting block is installed at the upper end of the fixing frame, and an opening and closing hydraulic rod is installed on the inner side of the connecting block.
[0009] Furthermore, the upper and lower ends of the punch are equipped with support columns, and the ends of the support columns are equipped with frames.
[0010] Furthermore, the side of the frame is provided with a clamping mold assembly to increase the tightness of the mold closing, and the number of clamping mold assemblies is provided in two sets.
[0011] Furthermore, the clamping assembly includes a mounting plate and a movable hydraulic rod, with the movable hydraulic rod mounted on the side of the mounting plate.
[0012] Furthermore, the clamping mold assembly also includes a side plate and a clamping mold frame, with the output end of the movable hydraulic rod equipped with the side plate, and the upper and lower ends of the side plate equipped with the clamping mold frame.
[0013] This utility model provides an aluminum profile extrusion die assembly with pressure compensation function, which has the following beneficial effects:
[0014] 1. This utility model adjusts the contact area between the end of the adjusting block and the metal flow area by controlling the adjusting block with a micro hydraulic rod. When the sensor built into the flow sleeve detects that the pressure in the area is too low (the flow rate is too fast), the adjusting block extends, reducing the cross-sectional area of the metal flow in that area, increasing resistance, and increasing pressure. When the pressure is too high (the flow rate is too slow), the adjusting block retracts, expanding the flow area and reducing resistance, so that the flow rate of the aluminum profile is stable during extrusion, avoiding the surface defects caused by the metal pulling against each other in the die hole due to the difference in flow rate.
[0015] 2. This utility model uses two sets of fixed frames to fix the convex mold and the concave mold respectively. The opening and closing hydraulic rod controls the opening and closing of the concave mold and the convex mold by telescopic control. The frame supports and fixes the convex mold with support columns as the base point for mold closing. The mounting plate is used for the installation and fixing of the moving hydraulic rod. The side plate and the clamping mold frame move to the side of the mold under the drive of the moving hydraulic rod and engage with the two fixed frames. The outer side of the fixed frame and the inner side of the U-shaped clamping mold frame are interference fit, which performs mold clamping treatment on the mold after mold closing.

[0020] The embodiments of this utility model will be described in further detail below with reference to the accompanying drawings and examples. The following examples are for illustrative purposes only and should not be construed as limiting the scope of this utility model.
[0021] like Figure 1 As shown, an aluminum profile extrusion die assembly with pressure compensation function includes a punch 1 and an adjusting assembly 3. A die 2 is provided on the right side of the punch 1. A clamping die assembly 10 for increasing the die closing tightness is provided on the side of the frame 9, and two sets of clamping die assemblies 10 are provided. Each clamping die assembly 10 includes a mounting plate 1001 and a movable hydraulic rod 1002. The movable hydraulic rod 1002 is mounted on the side of the mounting plate 1001. The mounting plate 1001 is used for mounting and fixing the movable hydraulic rod 1002. 10 also includes a side plate 1003 and a clamping mold frame 1004. The output end of the movable hydraulic rod 1002 is equipped with the side plate 1003. The side plate 1003 and the clamping mold frame 1004 are moved to the side of the mold under the drive of the movable hydraulic rod 1002 to engage with the two fixed frames 5. The upper and lower ends of the side plate 1003 are equipped with the clamping mold frame 1004. The outer side of the fixed frame 5 and the inner side of the U-shaped clamping mold frame 1004 are interference-fitted to perform clamping treatment on the mold after mold closing. The left side of the flow sleeve 301 is connected to the extrusion feed cylinder 11.
[0022] like Figure 2As shown, the adjustable adjustment component 3 for pressure compensation is located on the left side of the punch 1. The adjustment component 3 includes a flow guide sleeve 301, an adjustment groove 302, an adjustment block 303, a micro hydraulic rod 304, and a fixing plate 305. The inner wall surface of the flow guide sleeve 301 is provided with an adjustment groove 302. The flow guide sleeve 301 and the adjustment groove 302 are an integrated structure. Two adjustment blocks 303 are symmetrically arranged about the vertical central axis of the flow guide sleeve 301. The adjustment blocks 303 are controlled by the micro hydraulic rod 304 to adjust the contact area between the end of the adjustment block 303 and the metal flow area. The inner wall surface of the adjustment groove 302 is provided with an adjustment groove 302. The part is equipped with an adjusting block 303, and a miniature hydraulic rod 304 is installed on the side of the adjusting block 303. When the built-in sensor of the flow sleeve 301 detects that the pressure in the area is too low (the flow rate is too fast), the adjusting block 303 extends, reduces the cross-sectional area of metal flow in that area, increases resistance, and increases pressure. When the pressure is too high (the flow rate is too slow), the adjusting block 303 retracts, expands the flow area, and reduces resistance, so that the flow rate of the aluminum profile is stable during extrusion, and avoids the surface defects caused by the metal pulling against each other in the die hole due to the difference in flow rate. The fixed end of the miniature hydraulic rod 304 is connected to a fixing plate 305.
[0023] like Figure 3 As shown, a feed sleeve 4 is provided on the right side of the concave mold 2, and a fixing frame 5 is installed on the outside of the concave mold 2. The two sets of fixing frames 5 are fixedly connected to the convex mold 1 and the concave mold 2 respectively. A connecting block 6 is installed on the upper end of the fixing frame 5, and an opening and closing hydraulic rod 7 is installed on the inner side of the connecting block 6. The opening and closing hydraulic rod 7 controls the opening and closing of the concave mold 2 and the convex mold 1 by extension and retraction. Support columns 8 are installed at the upper and lower ends of the convex mold 1, and a frame 9 is installed at the end of the support column 8. The frame 9 supports and fixes the convex mold 1 through the support column 8 as the base point for mold closing.
[0024] In summary, this aluminum profile extrusion die assembly with pressure compensation function is first based on... Figures 1-3The structure shown in the diagram, during mold closing, the opening and closing hydraulic rod 7 retracts to control the closing of the concave mold 2 and the convex mold 1. Then, the side plate 1003 and the clamping frame 1004 move to the side of the mold under the drive of the moving hydraulic rod 1002 to engage with the two fixed frames 5. The outer side of the fixed frame 5 and the inner side of the U-shaped clamping frame 1004 are interference-fitted to perform clamping treatment on the mold after mold closing. After the mold closes, the extrusion feeding cylinder 11 extrudes the aluminum profile material into the guide sleeve 301 and the closed convex mold 1 and concave mold 2. When the built-in sensor in the guide sleeve 301... When the detector detects that the pressure in the area is too low (flow rate is too fast), the adjusting block 303 is extended under the control of the micro hydraulic rod 304 to adjust the contact area between the end of the adjusting block 303 and the metal flow area, thereby reducing the cross-sectional area of the metal flow in that area, increasing resistance, and increasing pressure. When the pressure is too high (flow rate is too slow), the adjusting block 303 retracts to expand the flow area and reduce resistance, so that the flow rate of the aluminum profile is stable during extrusion, avoiding the surface defects caused by the metal pulling against each other in the die hole due to the flow rate difference. The feed sleeve 4 plays an auxiliary supporting role for the extruded aluminum profile.
