[0022] The technical solutions in the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of this application without creative effort are within the scope of protection of this application.

[0023] The present application will now be described in detail with reference to the accompanying drawings and specific embodiments.

[0024] Example

[0025] like Figures 1-5As shown, a cable extrusion molding device that facilitates die head replacement includes: an extrusion device 1, an extrusion tube 101 installed at one end of the extrusion device 1, a feed hopper 102 installed at the top of the extrusion device 1, a mounting block 103 installed at the outer end of the extrusion tube 101, an extrusion head 104 installed at the outer end of the mounting block 103, a plurality of fixing screw holes 105 opened on the outer side of the mounting block 103, a plurality of mounting screw holes 106 opened on the outer side of the extrusion head 104, and a support assembly disposed at the bottom of the extrusion head 104. The support assembly includes: a support base 2, a movable seat 201, a movable cylinder 202, a telescopic rod a 203, a lifting frame 204, a lifting cylinder 205, and a telescopic rod b 206.

[0026] The extrusion equipment 1 is equipped with a servo motor 107 on one side of its outer end. The extrusion tube 101 is equipped with a spiral auger connected to the output end of the servo motor 107. A heating jacket is installed on the inner wall of the extrusion tube 101. When the extrusion equipment 1 is in use, the raw material is poured into the feed hopper 102 according to the ratio. The feed hopper 102 is connected to the extrusion tube 101. Then, the servo motor 107 and the heating jacket are started. The servo motor 107 drives the spiral auger to rotate inside the extrusion tube 101. The raw material enters the extrusion tube 101 under the action of gravity and is transported to the extrusion head 104 by the spiral auger. The heating jacket heats the extrusion tube 101 and conducts the heat to the inside of the extrusion tube 101, so that the raw material inside the extrusion tube 101 is heated and melted. The spiral auger continues to rotate and pushes the melted raw material to the extrusion head 104 to complete the processing of the cable sheath.

[0027] When using the extruder 104, one end of the extruder 104 is tightly attached to the outer end of the mounting block 103, that is, the mounting screw hole 106 on the outer side of the extruder 104 is aligned with the fixing screw hole 105 on the outer side of the mounting block 103. At this time, a bolt is screwed into the mounting screw hole 106 and through the fixing screw hole 105. The bolt is then screwed into the nut and tightened to fix it. The extruder 104 and the extrusion tube 101 are then installed and used together. When it is necessary to produce cable sheaths of different diameters, the extruder 104 can be removed from the outer end of the mounting block 103 separately. Since the size of the extrusion chamber inside each extruder 104 is different, an extruder 104 with a suitable cavity can be selected for installation and use according to production needs, thereby meeting the cable sheath production requirements.

[0028] Among them, a support base 2 is installed on one side of the bottom of the extrusion equipment 1, and a movable seat 201 is provided on the top of the support base 2. A movable cylinder 202 is installed on one side of the bottom of the extrusion equipment 1. A telescopic rod a203 is installed at the output end of the movable cylinder 202. The telescopic rod a203 is connected to the movable seat 201. A lifting frame 204 is provided on the top of the movable seat 201. Lifting cylinders 205 are installed on both sides of the top of the movable seat 201. A telescopic rod b206 is installed at the output end of the top of the lifting cylinder 205. The telescopic rod b206 is connected to the lifting frame 204.

[0029] When disassembling and replacing the extruder head 104, start the moving cylinder 202 to drive the telescopic rod a203 to push the moving seat 201 to the right, so that the moving seat 201 moves the lifting frame 204 to the bottom of the extruder head 104. Since there are multiple bolts installed on the outside of the extruder head 104, first remove the bolts and nuts at the bottom of the extruder head 104. Then start the lifting cylinder 205 to drive the telescopic rod b206 to push the lifting frame 204 upward, so that the bottom end of the extruder head 104 enters the lifting frame 204 and is supported and placed. Then remove the bolts and nuts at the top of the extruder head 104. When disassembling the extruder head 104, no worker is needed to hold it. This ensures that the extruder head 104 is stably placed after disassembly, preventing the extruder head 104 from falling and avoiding burns to the worker's hands.

[0030] When the lifting frame 204 is in use, the length and width of the inside of the lifting frame 204 are larger than the length and width of the extruder 104, so that the extruder 104 can be inserted into the lifting frame 204 and supported for disassembly.

[0031] After the lifting frame 204 is used, the telescopic rod b206 drives the lifting frame 204 to move downward, reducing the height of the lifting frame 204. Then the telescopic rod a203 pulls the moving seat 201 to the right to return to its original position, so that the moving seat 201 and the lifting frame 204 can be hidden and placed without affecting the normal use of the extrusion equipment 1.

[0032] The movable seat 201 is equipped with limit sliders 207 on both sides of its bottom. The support base 2 has limit grooves 208 on both sides of its top that are slidably connected to the limit sliders 207. When the telescopic rod a203 pushes the movable seat 201 to move left and right, the limit sliders 207 on both sides of the bottom of the movable seat 201 will be pushed and slide synchronously in the limit grooves 208, ensuring that the movable seat 201 runs smoothly, reducing wear between the movable seat 201 and the support base 2, and preventing damage to the movable seat 201.

[0033] The support base 2 has a front baffle 211 installed on one side of its top and a rear baffle 212 installed on the other side of its top. The lifting frame 204 is located between the front baffle 211 and the rear baffle 212. When the moving cylinder 202, the moving seat 201, the lifting cylinder 205 and the lifting frame 204 are in use, the front baffle 211 and the rear baffle 212 can provide anti-collision protection to prevent the moving cylinder 202, the moving seat 201, the lifting cylinder 205 and the lifting frame 204 from being damaged by collisions with external objects.

[0034] The support frame 204 has cooling fans 209 fixed to both sides of its outer end by bolts. The support frame 204 has heat dissipation vents 210 on both sides of its interior that communicate with the cooling fans 209. After the support frame 204 supports and places the extruder head 104 and is disassembled, the cooling fans 209 are started. The cooling fans 209 blow air into the extruder head 104 through the heat dissipation vents 210, which can accelerate the heat dissipation and cooling of the extruder head 104. After the extruder head 104 is cooled down, the lifting cylinder 205 is activated to drive the telescopic rod b206 to move the support frame 204 and the extruder head 104 downward, so that the extruder head 104 moves from a high position to a low position. This makes it easy for workers to take out the extruder head 104 placed inside the support frame 204, which saves effort when changing the die head. After the extruder head 104 is cooled down, workers are also prevented from being burned.

[0035] The cooling fan 209 has gaps between itself and the front baffle 211 and the rear baffle 212. When the telescopic rod b206 moves the lifting frame 204 up and down, the cooling fan 209 has gaps between itself and the front baffle 211 and the rear baffle 212, which can effectively prevent the cooling fan 209 from being damaged by collision with the front baffle 211 and the rear baffle 212.

[0036] Working principle:

[0037] When using extrusion equipment 1, the raw materials are poured into the feed hopper 102 according to the specified ratio. The feed hopper 102 is connected to the extrusion tube 101. Then, the servo motor 107 and the heating jacket are started. The servo motor 107 drives the auger to rotate inside the extrusion tube 101. The raw materials enter the extrusion tube 101 under gravity and are conveyed to the extrusion head 104 by the rotating auger. The heating jacket heats the extrusion tube 101, transferring heat to the inside of the extrusion tube 101, causing the raw materials inside the extrusion tube 101 to melt. The auger continues to rotate, pushing the melted raw materials towards the extrusion head 104, completing the processing of the cable sheath. When using the extrusion head 104, the extrusion head 104 is... One end is tightly attached to the outer end of the mounting block 103, that is, the mounting screw hole 106 on the outer side of the extruder 104 is aligned with the fixing screw hole 105 on the outer side of the mounting block 103. At this time, a bolt is screwed into the mounting screw hole 106 and through the fixing screw hole 105. The bolt is then screwed into the nut and tightened to fix it, thereby installing the extruder 104 and the extrusion tube 101 for use. When it is necessary to produce cable sheaths of different diameters, the extruder 104 can be removed from the outer end of the mounting block 103 separately. Since the size of the extrusion chamber inside each extruder 104 is different, an extruder 104 with a suitable cavity can be selected for installation and use according to production needs, thereby meeting the cable sheath production requirements.

[0038] When disassembling and replacing the extruder head 104, start the moving cylinder 202 to drive the telescopic rod a203 to push the moving seat 201 to the right, so that the moving seat 201 moves the lifting frame 204 to the bottom of the extruder head 104. Since there are multiple bolts installed on the outside of the extruder head 104, first remove the bolts and nuts at the bottom of the extruder head 104. Then start the lifting cylinder 205 to drive the telescopic rod b206 to push the lifting frame 204 upward, so that the bottom end of the extruder head 104 enters the lifting frame 204 and is supported and placed. Then remove the bolts and nuts at the top of the extruder head 104. No worker is needed to hold the extruder head 104 when disassembling it, ensuring that the extruder head 104 is stably placed after disassembly and preventing the extruder head 104 from falling.

[0039] After the support frame 204 supports and places the extruder head 104 and is disassembled, the cooling fan 209 is started. The cooling fan 209 blows air into the heat dissipation port 210, which can accelerate the heat dissipation and cooling of the extruder head 104. After the extruder head 104 cools down and is no longer hot, the lifting cylinder 205 is started to drive the telescopic rod b206 to move the support frame 204 and the extruder head 104 downward, so that the extruder head 104 moves from a high position to a low position, making it easier for the worker to take out the extruder head 104 placed inside the support frame 204. This achieves labor-saving die replacement and also prevents the worker from being burned after the extruder head 104 is cooled down.
