Description

Technical Field

[0001] This invention relates to the field of oil pipe blow molding technology, specifically a blow molding mold for processing automotive oil pipes. Background Technology

[0002] Automotive fuel lines serve to return excess fuel to the fuel tank, thereby reducing fuel consumption. Automotive fuel line manufacturing involves injecting raw materials into a mold for fuel line production and then blow molding them.

[0003] If the raw material for oil pipe processing is not laid evenly inside the mold, the oil pipe after blow molding may have gaps in some areas due to uneven thickness. It may also cause uneven thickness of the oil pipe sidewall. When demolding, the sidewall of the oil pipe is usually designed with concave and convex shapes. The mold that matches the oil pipe will match the formed oil pipe. During the demolding process, defects may easily occur. Summary of the Invention

[0004] The purpose of this invention is to solve the problem that uneven laying of oil pipe raw materials can easily lead to local defects and uneven thickness of the oil pipe. This invention provides a blow molding mold for processing automotive oil pipes.

[0005] To achieve the above objectives, the present invention specifically adopts the following technical solution:

[0006] A blow molding die for processing automotive oil pipes includes a limiting mechanism. A control mechanism is sleeved around the outer ring of the limiting mechanism. A conveying mechanism is provided on the inner side of the bottom end of the control mechanism. The conveying mechanism includes an inlet, a movable strip, a shrink tube, and a support frame. The movable strip and the shrink tube are both connected to the bottom side of the inlet. The movable strip is disposed between the gaps of the shrink tubes. The outer end of the support frame is inserted into the inner side of the shrink tube. A mold ring is provided below the conveying mechanism. The bottom end of the control mechanism is connected to the outer end of the mold ring. A rotating drum mechanism is sleeved on the bottom end of the inner ring of the mold ring. A buffer frame is provided in the middle of the rotating drum mechanism. A mold frame mechanism is provided at the bottom end of the rotating drum mechanism. A base plate is provided on the outer side of the bottom end of the mold frame mechanism.

[0007] Furthermore, the limiting mechanism includes a control ring, a telescopic ring, a cylinder interface, and a connecting rod. The bottom end of the connecting rod is fixedly connected to the top end of the control mechanism. Pulling the connecting rod moves it toward the axis, causing the control mechanism to clamp the outer ring of the conveying mechanism toward the axis.

[0008] Furthermore, the inner side of the control ring is slidably connected to the outer side of the telescopic ring, the inner ring of the telescopic ring is sleeved on the outer ring of the cylinder interface, the top end of the connecting rod is fixedly connected to both ends of the control ring, the inner ring of the control ring moves towards the middle part around the outer ring of the telescopic ring, and the part that can pull the connecting rod is pulled towards the axis.

[0009] Furthermore, the control mechanism includes a movable block, a top buckle frame, a collar, a connecting plate, a support rod, a tray, and a buckle plate. The top of the movable block is fixedly connected to the bottom of the limiting mechanism. The bottom side of the top buckle frame is located at the top edge of the feed inlet. The inner side of the connecting plate is inserted around the side wall of the feed inlet. The bottom side of the tray is movably connected to the bottom edge of the feed inlet. The bottom end of the buckle plate is fixedly connected to the outer ring of the mold frame mechanism. The control mechanism clamps the outer ring of the conveying mechanism towards the axis. The inner ring of the top buckle frame wraps around the top edge of the feed inlet. The inner side of the collar is located on the side of the movable bar.

[0010] Furthermore, the top side of the top buckle is fixedly connected to the bottom end of the movable block, the top end of the collar is fixedly connected to the outer end of the top buckle, the bottom end of the collar is connected to the outer end of the tray, the top end of the buckle plate is connected through to the middle of the outer side of the collar, the outer end of the connecting plate is fixedly connected to the top end of the support rod, the bottom end of the support rod is fixedly connected to the outer end of the top side of the tray, the part of the control mechanism clamps the outer ring of the conveying mechanism towards the axis, the inner ring of the top buckle wraps around the top edge of the feed pipe, and the inner side of the collar is located on the side of the movable bar.

[0011] Furthermore, the bottom side of the movable strip and the shrink tube are movably connected to the inner side of the rotary drum mechanism. When the outer ring of the feed pipe reduces its diameter towards the axial center, the shrink tube moves closer to the middle part, and the outer end of the movable strip is squeezed by the gap in the side wall of the shrink tube.

[0012] Furthermore, the rotary drum mechanism includes a forming frame, a component strip, and a cross frame. The top side of the forming frame is inserted into the bottom inner side of the mold ring, and the bottom ends of the component strip and the cross frame are connected to the top of the mold frame mechanism. When the inner diameter of the forming frame and the component strip gradually decreases, the raw material can be gradually squeezed in along the inner edge of the mold frame mechanism.

[0013] Furthermore, the outer side of the component strip is inserted into the inner side of the forming frame, and the outer side of the component strip is sleeved on the inner side of the cross frame. The cross-tightening of the side walls of the cross frame will cause the gap between the side walls of the component strip to shrink, thus tightening the raw material towards the center.

[0014] Furthermore, the mold frame mechanism includes a collar, a telescopic frame, an outer assembly block, a cover tube, a cut-off area, and an annular area. The top of the telescopic frame is sleeved on the bottom of the rotary drum mechanism. The outer side of the cover tube is located on the inner side of the chassis. The outer assembly block will also contract, and the sidewall of the outer assembly block will be squeezed towards the axial center to gather the raw materials in the middle.

[0015] Furthermore, the inner side of the collar is connected to the outer side of the telescopic frame. Both the collar and the telescopic frame are elastically connected to the top side of the outer assembly. The cover tube and the cut-off area are spaced apart and connected together. The top end of the cover tube is fixedly connected to the bottom outer end of the outer assembly. The outer assembly, the cover tube, and the cut-off area are all assembled in a row of blocks. When the cut-off area and the annular area are stretched, the cut-off area will also drive the inner ring of the cover tube to stretch outward, which can facilitate the demolding of the oil pipe later.

[0016] Compared with the prior art, the present invention provides a blow molding die for processing automotive oil pipes, which has the following beneficial effects:

[0017] 1. The blow molding mold for processing automotive oil pipes, through the coordinated use of the control mechanism and the conveying mechanism, evenly shrinks the side wall of the conveying mechanism, spreading the raw material evenly. This ensures that the raw material is spread evenly during the blow molding process, avoiding gaps in the oil pipe after blow molding.

[0018] 2. The blow molding mold for processing automotive oil pipes, through the cooperation between the rotary drum mechanism and the mold frame mechanism, shrinks the mold frame mechanism, which can gather the raw material in the middle part, making it easier to pour the raw material evenly into the mold frame mechanism and ensuring that the thickness around the formed oil pipe is uniform.

[0019] 3. The blow molding mold for processing automotive oil pipes, after being stretched by the cut-off area and the annular area inside the mold frame mechanism, the cut-off area and the inner ring of the cover tube are stretched outward in a block shape, which can easily complete the demolding and avoid oil pipe demolding loss.

Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0029] like Figures 1-7 As shown, a blow molding die for processing automotive oil pipes includes a limiting mechanism 1. A control mechanism 2 is sleeved around the outer ring of the limiting mechanism 1. A conveying mechanism 3 is provided on the inner side of the bottom end of the control mechanism 2. The conveying mechanism 3 includes a feed inlet 301, a movable strip 302, a shrink tube 303, and a support frame 304. The movable strip 302 and the shrink tube 303 are both connected to the bottom side of the feed inlet 301. The movable strip 302 is disposed between the gaps of the shrink tube 303. The outer end of the support frame 304 is inserted into the inner side of the shrink tube 303. A mold ring 4 is provided below the conveying mechanism 3. The bottom end of the control mechanism 2 is connected to the outer end of the mold ring 4. A rotating drum mechanism 5 is sleeved on the bottom end of the inner ring of the mold ring 4.

A base plate 8 is provided on the outer side of the bottom end of the mold frame mechanism 7.

[0030] like Figure 1As shown, in some embodiments, the limiting mechanism 1 includes a control ring 101, a telescopic ring 102, a cylinder interface 103, and a connecting rod 104. The bottom end of the connecting rod 104 is fixedly connected to the top end of the control mechanism 2. The inner side of the control ring 101 is slidably connected to the outer side of the telescopic ring 102. The inner ring of the telescopic ring 102 is sleeved on the outer ring of the cylinder interface 103. The top end of the connecting rod 104 is fixedly connected to both ends of the control ring 101. The raw material of the injection molding tube is injected from the top interior of the conveying mechanism 3. The two ends of the control limiting mechanism 1 are tightened towards the axial part. With the part of the cylinder interface 103 as the axial part, the telescopic ring 102 surrounds the outer ring of the cylinder interface 103. The inner ring of the control ring 101 moves towards the middle part around the outer ring of the telescopic ring 102. The part of the connecting rod 104 can be pulled to move towards the axial part, which drives the part of the control mechanism 2 to clamp the outer ring of the conveying mechanism 3 towards the axial part.

[0031] like Figure 1 As shown, in some embodiments, the control mechanism 2 includes a movable block 201, a top buckle 202, a collar 203, a connecting plate 204, a support rod 205, a tray 206, and a buckle plate 207. The top of the movable block 201 is fixedly connected to the bottom of the limiting mechanism 1. The bottom side of the top buckle 202 is located at the top edge of the feed inlet 301. The inner side of the connecting plate 204 is inserted around the side wall of the feed inlet 301. The bottom side of the tray 206 is movably connected to the bottom edge of the feed inlet 301. The bottom end of the buckle plate 207 is fixedly connected to the outer ring of the mold frame mechanism 7. The top side of the top buckle 202 is fixedly connected to the bottom end of the movable block 201. The top of the collar 203 is fixedly connected to the outer end of the top buckle 202. The bottom end of the collar 203 is connected to the outer end of the tray 206. The top of the buckle plate 207 extends through... The outer middle of the collar 203 is connected to the outer end of the connecting plate 204, which is fixedly connected to the top of the support rod 205. The bottom end of the support rod 205 is fixedly connected to the top outer end of the tray 206. The part of the control mechanism 2 clamps the outer ring of the conveying mechanism 3 towards the axis. The inner ring of the top buckle 202 wraps around the top edge of the feed pipe 301. The inner side of the collar 203 is located on the side of the movable bar 302. The top side of the tray 206 is located on the bottom edge of the feed pipe 301 and the movable bar 302. The top buckle 202, collar 203 and tray 206 form a transverse U-shape that wraps around the upper and lower edges of the conveying mechanism 3. The connecting plate 204 and the support rod 205 are inserted between the feed pipe 301 and the tray 206. The control mechanism 2 can control the transverse contraction of the side wall of the conveying mechanism 3.

[0032] like Figure 1 and Figure 2As shown, in some embodiments, the bottom sides of the movable strip 302 and the shrink tube 303 are movably connected to the inner side of the rotary drum mechanism 5. When the outer ring of the feed pipe 301 shrinks towards the axial part, the shrink tube 303 moves towards the middle part, and the outer end of the movable strip 302 is squeezed by the gap of the side wall of the shrink tube 303. After the raw material located in the inner ring of the conveying mechanism 3 is squeezed by the rotation of the conveying mechanism 3 and the side wall of the conveying mechanism 3, the raw material in the inner side will be evenly mixed after the side wall of the conveying mechanism 3 rotates, so that the amount of raw material stored in the inner side of each interval of the shrink tube 303 is balanced, and the raw material can be evenly injected around the inner side of the rotary drum mechanism 5.

[0033] like Figure 1 and Figure 3 As shown, in some embodiments, the rotary drum mechanism 5 includes a forming frame 501, a component strip 502, and a cross frame 503. The top side of the forming frame 501 is inserted into the bottom inner side of the mold ring 4. The bottom ends of the component strip 502 and the cross frame 503 are connected to the top of the mold frame mechanism 7. The outer side of the component strip 502 is inserted into the inner side of the forming frame 501 and sleeved on the inner side of the cross frame 503. The component strip 502 is vertical. The cross frame 503 is cross-stretching. The forming frame 501, the component strip 502, and the cross frame 503 are all in a stretching state. When the inner diameter of the forming frame 501 and the component strip 502 gradually decreases, the raw material can be gradually squeezed into the inner edge of the mold frame mechanism 7. The cross-tightening of the side wall of the cross frame 503 will cause the gap between the side walls of the component strip 502 to tighten, thus tightening the raw material towards the center.

[0034] like Figure 1 , Figures 3-7 As shown, in some embodiments, the mold frame mechanism 7 includes a collar 701, a telescopic frame 702, an outer assembly block 703, a cover tube 704, a cut-off area 705, and an annular area 706. The top end of the telescopic frame 702 is sleeved on the bottom end of the rotating drum mechanism 5. The outer side of the cover tube 704 is disposed on the inner side of the chassis 8. The inner side of the collar 701 is connected through to the outer side of the telescopic frame 702. Both the collar 701 and the telescopic frame 702 are elastically connected to the top side of the outer assembly block 703. The cover tube 704... 4. The cut-off areas 705 are spaced apart and connected together. The top of the cover tube 704 is fixedly connected to the bottom outer end of the outer block 703. The outer block 703, cover tube 704 and cut-off areas 705 are all assembled in a row of blocks. When the raw material is poured, the rotating cylinder mechanism 5 will also drive the side wall of the mold frame mechanism 7 to shrink. Then the part of the outer block 703 will also shrink. The side wall of the outer block 703 is squeezed towards the axis, and the raw material is gathered in the middle part, which can facilitate the completion of the mold pouring.

[0035] like Figure 1 , Figures 5-7As shown, since the outer side of the oil pipe is segmented, the segmented injection molding of the oil pipe is formed by the inner side of the cover tube 704 and the cut-off area 705. The cover tube 704 and the cut-off area 705 correspond to the concave and convex parts of the side wall of the oil pipe. When the cut-off area 705 and the annular area 706 are stretched, the cut-off area 705 will drive the inner ring of the cover tube 704 to stretch outward, which can facilitate the demolding of the oil pipe later.
