Description

Technical Field

[0001] The utility model relates to the technical field of plastic extrusion moulds, in particular to a novel plastic extrusion mould. Background Art

[0002] Plastic extrusion molds are molds for producing plastic profile products with continuous shapes. They are also called extrusion molds, extrusion molding heads or die heads. Usually, powdered or granular polymers are added to the extruder barrel. Under the action of the screw or plunger, the polymer moves forward along the screw groove or barrel and gradually melts to become a viscous fluid. Then, it can be formed into products of the desired shape through the mold set at the end of the barrel.

[0003] For example, a plastic extrusion mold with adjustable inner diameter with application number CN202321725735.1 includes an operating table, a second mold is welded on the top of the operating table, and a connecting device is provided on the outer wall of the second mold, the connecting device includes a second electric push rod, a first placement groove, a first limit groove, a connecting plate, and a second placement groove, the second electric push rod is installed on the outer wall of the second mold through a mounting plate, a first placement groove is opened on one side of the second mold, a first limit groove is opened on the outer wall of the second mold, a connecting plate is slidably installed on the inner wall of the first limit groove, and a second placement groove is opened through the outer wall of the connecting plate. This plastic extrusion mold with adjustable inner diameter is no longer limited to adjusting the extrusion mold, and the device for holding plastic can also be adjusted in size according to actual conditions, so as to adjust the capacity of the plastic loaded. When the capacity is too much, there is no need to keep adding back and forth, and the operation is easier and more convenient.

[0004] When the plastic extrusion mold proposed in the above patent is used, the material to be processed needs to be added to the mold through the feeding port first. Due to the limited diameter of the feeding port, the material is prone to accumulation or blockage at the feeding port when it is discharged through the discharge port, thereby affecting the discharge speed of the material.

[0005] So we proposed a new type of plastic extrusion die to solve the problems mentioned above. Utility Model Content

[0006] The utility model aims to provide a novel plastic extrusion die to solve the problem proposed in the background art that due to the limited caliber of the feed port, materials are easily accumulated or blocked at the feed port when being discharged through the discharge port, thereby affecting the discharge speed of the materials.

[0007] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a novel plastic extrusion die, comprising a support assembly and an extrusion die assembly arranged in the middle of the upper end of the support assembly, a feeding assembly is arranged on one side of the upper end of the extrusion die assembly, and the feeding assembly is used to inject materials into the inner cavity of the extrusion die assembly for processing;

[0008] The feeding assembly includes a containing mechanism and a stirring mechanism movably installed in the inner cavity of the containing mechanism. Sliding assemblies are fixedly installed on both sides of the upper end of the stirring mechanism. The sliding assemblies are arranged to drive the stirring mechanism to rotate in the inner cavity of the containing mechanism.

[0009] Preferably, the accommodating mechanism comprises a hollow cylinder and a limiting groove provided in the middle of the outer circumference of the upper end of the hollow cylinder.

[0010] Preferably, the stirring mechanism comprises a concave stirring rod and docking rods fixedly mounted on both sides of the upper end of the concave stirring rod.

[0011] Preferably, an extension rod is fixedly mounted on the middle portion of the upper end of the concave stirring rod, and long scraping blocks are fixedly mounted on both sides of the outer wall of the concave stirring rod.

[0012] Preferably, the sliding assembly comprises an arc-shaped insertion block and short columns fixedly mounted on both sides of the upper end of the arc-shaped insertion block, a connecting plate is mounted on the upper end of the short column, and a docking plate is fixedly mounted on one end of the connecting plate.

[0013] Preferably, a through groove is formed at the upper and lower ends of one side of the outer wall of the arc-shaped insertion block, and a roller is movably mounted in the inner cavity of the through groove via a movable shaft.

[0014] Compared with the prior art, the beneficial effects of the utility model are:

[0015] 1. The operator pours the material into the inner cavity of the hollow cylinder. During the material discharge process, the connecting plate, short column and arc-shaped insertion block fixed at both ends are driven to move together by rotating the docking plate. Since a concave stirring rod is fixedly installed on the middle part of the upper end of the arc-shaped insertion block through the docking rod, the docking plate drives the concave stirring rod to rotate in the inner cavity of the hollow cylinder, thereby causing the material accumulated and blocked in the inner cavity of the hollow cylinder to shake, and then the material accumulated in the inner cavity of the hollow cylinder is stirred and discharged, thereby improving the discharge efficiency of the hollow cylinder.

[0016] 2. When the concave stirring rod drives the extension rod to rotate and discharge materials, the scraping long blocks fixedly installed on both sides of the outer wall of the concave stirring rod will scrape the materials sticking to the inner wall of the hollow cylinder, thereby preventing the materials from sticking to the inner wall of the hollow cylinder.

[0022] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0023] Example 1: Please refer to Figure 1-3 A new type of plastic extrusion mold includes a support component 1 and an extrusion mold component 2 arranged in the middle of the upper end of the support component 1. A feed component 3 is arranged on one side of the upper end of the extrusion mold component 2. The feed component 3 is used to inject materials into the inner cavity of the extrusion mold component 2 for processing.

[0024] The feeding assembly 3 includes a containing mechanism 31 and a stirring mechanism 32 movably installed in the inner cavity of the containing mechanism 31. Sliding assemblies 33 are fixedly installed on both sides of the upper end of the stirring mechanism 32. The sliding assembly 33 is configured to drive the stirring mechanism 32 to rotate in the inner cavity of the containing mechanism 31.

[0025] The stirring mechanism 32 includes a concave stirring rod 321 and a docking rod 322 fixedly installed on both sides of the upper end of the concave stirring rod 321, an extension rod 323 is fixedly installed in the middle of the upper end of the concave stirring rod 321, and scraping long blocks 324 are fixedly installed on both sides of the outer wall of the concave stirring rod 321. The scraping long blocks 324 are arranged to clean the inner wall of the hollow cylinder 311 when the concave stirring rod 321 rotates in the inner cavity of the hollow cylinder 311.

[0026] The sliding assembly 33 includes an arc-shaped insertion block 331 and short columns 332 fixedly installed on both sides of the upper end of the arc-shaped insertion block 331, a connecting plate 333 is installed on the upper end of the short column 332, a docking plate 334 is fixedly installed on one end of the connecting plate 333, and the lower end of the docking rod 322 is fixedly installed on the middle part of the upper end of the arc-shaped insertion block 331. The docking plate 334 is set to drive the arc-shaped insertion block 331 to slide in the inner cavity of the limiting groove 312.

[0027] In this embodiment: the operator pours the material into the inner cavity of the hollow cylinder 311. During the material discharge process, the connecting plate 333, the short column 332 and the arc-shaped insertion block 331 fixed at both ends are driven to move together by rotating the docking plate 334. Since the concave stirring rod 321 is fixedly installed on the middle part of the upper end of the arc-shaped insertion block 331 through the docking rod 322, the docking plate 334 drives the concave stirring rod 321 to rotate in the inner cavity of the hollow cylinder 311, thereby causing the material accumulated and blocked in the inner cavity of the hollow cylinder 311 to shake, and then the material accumulated in the inner cavity of the hollow cylinder 311 is stirred and discharged, thereby improving the discharge efficiency of the hollow cylinder 311.

[0028] Embodiment 2: This embodiment is an improvement made on the basis of embodiment 1. For details, please refer to Figure 4 The accommodating mechanism 31 includes a hollow cylinder 311 and a limiting groove 312 opened in the middle of the outer circumference of the upper end of the hollow cylinder 311, an arc-shaped insertion block 331 is slidably installed at the lower end of the limiting groove 312, and the docking rod 322 is slidably installed in the inner cavity of the limiting groove 312.

[0029] A through groove 335 is provided at the upper and lower ends of one side of the outer wall of the arc-shaped insertion block 331, and a roller 336 is movably installed in the inner cavity of the through groove 335 through a movable shaft. The setting of the roller 336 is used to improve the smoothness of the arc-shaped insertion block 331 sliding in the inner cavity of the limiting groove 312.

[0030] In this embodiment: when the concave stirring rod 321 drives the extension rod 323 to rotate and discharge materials, the scraping long blocks 324 fixedly installed on both sides of the outer wall of the concave stirring rod 321 will scrape the materials stuck to the inner wall of the hollow cylinder 311, thereby preventing the materials from sticking to the inner wall of the hollow cylinder 311 and increasing the discharge space of the materials in the inner cavity of the hollow cylinder 311. Moreover, since the arc-shaped insertion block 331 rotates in the inner cavity of the limiting groove 312 following the docking plate 334, the setting of the roller 336 will assist the arc-shaped insertion block 331 to rotate, thereby improving the smoothness of the rotation of the concave stirring rod 321 in the inner cavity of the hollow cylinder 311.

[0031] Working principle: The operator pours the material into the inner cavity of the hollow cylinder 311. During the material unloading process, the connecting plate 334 is rotated to drive the connecting plate 333, the short column 332 and the arc-shaped insertion block 331 fixed at both ends to move together. Since the concave stirring rod 321 is fixedly installed at the middle part of the upper end of the arc-shaped insertion block 331 through the connecting rod 322, the connecting plate 334 drives the concave stirring rod 321 to rotate in the inner cavity of the hollow cylinder 311, thereby causing the accumulation to be blocked in the hollow cylinder. The material in the inner cavity of the cylinder 311 shakes to complete the material discharge. When the concave stirring rod 321 drives the extension rod 323 to rotate and discharge the material, the scraping long blocks 324 fixedly installed on both sides of the outer wall of the concave stirring rod 321 will scrape the material stuck on the inner wall of the hollow cylinder 311, and the material stuck on the inner wall of the hollow cylinder 311 will be scraped and discharged. In addition, since the arc-shaped insertion block 331 rotates in the inner cavity of the limiting groove 312 following the docking plate 334, the setting of the roller 336 will assist the arc-shaped insertion block 331 to rotate.
