Description

Technical Field

[0001] The present invention relates to the technical field of molding dies, and specifically to a molding die for the production of plastic masterbatch materials. Background Art

[0002] At present, masterbatch is a new type of special coloring agent for polymer materials, also called colorant. It is made by mixing pigments or dyes, carrier resins, and various additives in a certain proportion through processes such as mixing, melting, extrusion, and pelletizing. Masterbatch dies are special dies for producing masterbatch. Masterbatch is a new type of special coloring agent for polymer materials. During the production process, the quality and design of the die will directly affect the molding quality, dimensional accuracy, and production efficiency of the masterbatch; When the material is transferred into the molding cavity of the die, after the material is extruded from the extrusion head of the extruder, the space increases and it expands outward, resulting in gaps inside the material. After the material with gaps enters the molding cavity and cools and solidifies, holes appear inside, leading to an unsatisfactory molding effect. Summary of the Invention

[0003] To achieve the above objectives, the present invention is realized through the following technical solutions: A molding die for the production of plastic masterbatch materials, comprising: A molding component, which is used for shaping the molten masterbatch material. A connecting plate is fixedly installed at the top of the molding component; A cavity component, which is used to connect the extruder and keep the extruded material warm, and the bottom of the cavity component is fixedly connected to the molding component through the connecting plate; A material guiding component, which is used to conduct the extruded material to the molding component and eliminate the air inside the material during the transmission process, and the material guiding component is installed inside the cavity component; A connecting ring is fixedly connected to the top of the cavity component, and the cavity component is connected to the extrusion head of the extruder through the connecting ring; Among them, the material guiding component includes a gasket ring and a fixed sleeve. The gasket ring is fixedly installed on the top of the fixed sleeve. The outer side of the fixed sleeve is fixedly connected to the inner wall of the cavity component. The bottom of the fixed sleeve is fixedly connected to a hole cover. The bottom of the outer side of the hole cover is evenly provided with sleeve holes, and fixed tubes are fixedly connected to the sleeve holes of the hole cover. The bottom of the fixed tube is fixedly connected to a primary cavity tube. The bottom of the primary cavity tube is fixedly connected to a secondary cavity tube. The diameter of the primary cavity tube is larger than that of the secondary cavity tube. The diameter of the secondary cavity tube gradually decreases from top to bottom. Through the change in the diameters between the primary cavity tube and the secondary cavity tube, the molten material is gradually squeezed inward during flow, and the gap between the materials is gradually squeezed inward by the tube walls with gradually decreasing diameters around during flow, reducing the gap between the materials introduced into the forming cavity, and avoiding the situation where the internal gap of the material cannot be eliminated during the diversion, resulting in holes in the formed material and causing an unsatisfactory forming effect.

[0004] Preferably, the bottom of the secondary cavity tube is fixedly connected to a material guiding tube. The bottom end of the material guiding tube is communicated with the forming component, and the outer side of the material guiding tube is fixedly connected to the inner wall of the cavity component. A connecting rod is fixedly connected to the central position of the inner wall of the hole cover. A pressing block is slidably installed on the outer side of the connecting rod. A retaining ring is arranged at one end of the connecting rod close to the pressing block. Due to the elastic characteristics of the elastic pad, when the material extruded by the extruder enters the hole cover, the impact force causes the deformation of the elastic pad, making the elastic pad produce a resilience force, driving the pressing block to squeeze the incoming material in the extrusion direction, cooperating with the contact pressure of the extruder to squeeze the incoming material, coordinating with the change in the diameter of the secondary cavity tube to reduce the gap between the materials, and a resilient pad is fixedly connected between the retaining ring of the connecting rod and the pressing block.

[0005] Preferably, the forming component includes a top plate and a bottom plate. Rod holes are respectively opened at the edges of the top of the top plate, and guide rods are slidably installed at the rod holes of the top plate. The guide rods play a guiding role during the reciprocating movement in the forming process between the bottom plate and the top plate, avoiding deviation between the cavity grooves during the forming process, resulting in misalignment of the cavity shape and affecting the shape of the formed material. The bottom ends of the guide rods are fixedly connected to the top of the bottom plate, and the top plate is fixedly connected to the cavity component through a connecting plate. The bottom of the bottom plate is fixedly connected to the forming device. Fixed plates are fixedly connected to the opposite surfaces of the bottom plate and the top plate. Cavity grooves are fixedly connected to the opposite surfaces of the fixed plates. The cavity grooves are flush with the opposite surfaces of the fixed plates, and the top cavity groove is communicated with the bottom end of the material guiding tube.

[0006] Preferably, the cavity assembly includes an outer cavity tube. A sealing block is fixedly connected to the bottom of the outer cavity tube, and a front blocking block is fixedly connected to the top of the outer cavity tube. An inner cavity tube is fixedly connected between the sealing block and the front blocking block. The inner cavity tube is located inside the outer cavity tube. A communicating tube is fixedly connected to the outside of the outer cavity tube. The communicating tubes are symmetrically installed along the central position of the outer cavity tube. The bottom of the sealing block is fixedly connected to the top of the top plate through a connecting plate. A blocking ring and a front sealing ring are installed between the outer cavity tube and the inner cavity tube. The bottom of the blocking ring is fixedly connected to the top of the sealing block. A flow guiding plate is fixedly connected between the front sealing ring and the blocking ring. Due to the spiral shape of the flow guiding plate, after hot water enters the gap between the outer cavity tube and the inner cavity tube, it can flow along a specified route. At the same time, the heat in the hot water is transferred between the hot water, so that the temperature inside the inner cavity tube is always maintained within a safe range, avoiding solidification due to a decrease in temperature when the material is introduced, which may cause obstruction to the exported material. The flow guiding plate is a spiral metal plate.

[0007] Preferably, the front sealing ring and the blocking ring tightly seal between the outer cavity tube and the inner cavity tube. A elastic sleeve is fixedly connected between the front sealing ring and the front blocking block. The elastic sleeve is made of an elastic material. The inner wall of the inner cavity tube is fixedly connected to the outside of the fixed sleeve. Due to the elastic characteristics of the elastic sleeve, when it is necessary to quickly introduce hot water to increase the temperature inside the inner cavity tube, the water pressure increases, pushing the front sealing ring to squeeze the elastic sleeve, causing the elastic sleeve to deform and increasing the contact area between the hot water and the inner cavity tube, so that the temperature of the inner cavity tube can be quickly increased when it is relatively low. The top of the outside of the outer cavity tube is evenly provided with air holes, and the air holes are located between the front blocking block and the front sealing ring. The top of the front blocking block is fixedly connected to the bottom of the connecting ring.

[0008] The present invention provides a molding die for the production of plastic masterbatch materials. It has the following beneficial effects: First, in this molding die for the production of plastic masterbatch materials, through the change in the pipe diameter between the first-stage cavity tube and the second-stage cavity tube, the molten material is gradually squeezed inward during flow. The gap between the materials is gradually reduced by the pipe walls with gradually decreasing diameters on all sides during flow, reducing the gap between the materials introduced into the forming cavity, and avoiding the situation where the internal gap of the materials cannot be eliminated during diversion, resulting in holes inside the formed material and unsatisfactory forming effects.

[0009] Second, in this molding die for the production of plastic masterbatch materials, due to the elastic characteristics of the elastic pad, when the material extruded by the extruder enters the hole cover, the impact force causes the deformation of the elastic pad, making the elastic pad generate a resilience force, driving the pressing block to squeeze the incoming material in the extrusion direction. Cooperating with the contact pressure of the extruder, the incoming material is extruded, and in cooperation with the change in the pipe diameter of the second-stage cavity tube, the gap between the materials is reduced.

[0010] III. The molding die for the plastic masterbatch production materials guides the reciprocating movement of the guide rod during the molding process of the bottom plate and the top plate, avoiding deviation between the cavity grooves during the molding process, resulting in misalignment of the cavity shape and affecting the shape of the molded material.

[0011] IV. The molding die for the plastic masterbatch production materials has a spiral outer shape of the flow guide plate. After hot water enters the gap between the outer cavity tube and the inner cavity tube, it can flow along a specified route. At the same time, the heat in the hot water is transferred between the hot water, keeping the temperature inside the inner cavity tube within a safe range all the time, avoiding solidification due to temperature reduction when the material is introduced, which may block the exported material.

[0012] V. The molding die for the plastic masterbatch production materials, due to the elastic characteristics of the elastic sleeve, when it is necessary to quickly introduce hot water to increase the temperature inside the inner cavity tube, the water pressure increases, pushing the front sealing ring to squeeze the elastic sleeve, deforming the elastic sleeve and increasing the contact area between the hot water and the inner cavity tube, so that the temperature of the inner cavity tube can be quickly increased when it is relatively low.

[0015] The present invention will be further described in detail below in conjunction with the accompanying drawings and specific implementation manners. The embodiments of the present invention are given for the purpose of illustration and description, and are not exhaustive or limit the present invention to the disclosed form. Many modifications and variations are obvious to those of ordinary skill in the art. The embodiments are selected and described to better illustrate the principles and practical applications of the present invention, and enable those of ordinary skill in the art to understand the present invention and thus design various embodiments with various modifications suitable for specific purposes.

[0016] The first embodiment is as Figures 1 to 2 And Figures 7 to 8 As shown, the present invention provides a technical solution: a molding die for plastic masterbatch production materials, including: A molding component 1, which is used to shape the masterbatch material in a molten state. A connecting plate 5 is fixedly installed at the top of the molding component 1; A cavity component 2, which is used to connect an extruder and keep the extruded material warm. The bottom of the cavity component 2 is fixedly connected to the molding component 1 through the connecting plate 5; A material guiding component 3, which is used to conduct the extruded material to the molding component 1 and eliminate the air inside the material during transmission. The material guiding component 3 is installed inside the cavity component 2; A connecting ring 4 is fixedly connected to the top of the cavity component 2, and the cavity component 2 is connected to the extrusion head of the extruder through the connecting ring 4; Among them, the material guiding component 3 includes a cushion ring 301 and a fixing sleeve 302. The cushion ring 301 is fixedly installed on the top of the fixing sleeve 302. The outer side of the fixing sleeve 302 is fixedly connected to the inner wall of the cavity component 2. The bottom of the fixing sleeve 302 is fixedly connected to a hole cover 303. A plurality of sleeve holes are evenly formed at the bottom of the outer side of the hole cover 303, and fixing pipes 304 are fixedly connected to the sleeve holes of the hole cover 303. The bottom of the fixing pipe 304 is fixedly connected to a first-stage cavity pipe 305. The bottom of the first-stage cavity pipe 305 is fixedly connected to a second-stage cavity pipe 306. The material is guided by the fixing pipe 304 and flows along the inside of the first-stage cavity pipe 305 and the second-stage cavity pipe 306 to the material guiding pipe 307, and is guided to the molding component 1 through the material guiding pipe 307. At the same time, when the material passes through the second-stage cavity pipe 306, since the diameter of the second-stage cavity pipe 306 gradually decreases, the flowing material is squeezed inward, reducing the gap between the materials and reducing the air between the introduced materials. The diameter of the first-stage cavity pipe 305 is larger than the diameter of the second-stage cavity pipe 306, and the diameter of the second-stage cavity pipe 306 gradually decreases from top to bottom.

[0017] A guide pipe 307 is fixedly connected to the bottom of the secondary cavity pipe 306. The bottom end of the guide pipe 307 is communicated with the forming assembly 1, and the outer side of the guide pipe 307 is fixedly connected to the inner wall of the cavity assembly 2. A connecting rod 309 is fixedly connected to the central position of the inner wall of the hole cover 303. A pressing block 308 is slidably installed on the outer side of the connecting rod 309. A retaining ring is provided at one end of the connecting rod 309 close to the pressing block 308. When guiding the extruded molten material through the guiding assembly 3, the material enters through the space between the gasket ring 301 and the fixed sleeve 302, so that the material enters the inside of the hole cover 303. At the same time, under the extrusion pressure of the extruder, the material impacts the pressing block 308, and the pressing block 308 transmits the impact pressure to the elastic pad 310, causing the elastic pad 310 to deform. The pressing block 308 slides on the outer side of the connecting rod 309. At the same time, after the elastic pad 310 deforms, it generates a resilience force, so that the pressing block 308 cooperates with the extrusion pressure to extrude the material entering the hole cover 303 in all directions, so that the material enters the fixed pipe 304 through the sleeve holes, and an elastic pad 310 is fixedly connected between the retaining ring of the connecting rod 309 and the pressing block 308.

[0018] The second embodiment, on the basis of the first embodiment, please refer to Figures 3 to 4 As shown, the forming assembly 1 includes a top plate 11 and a bottom plate 15. Rod holes are formed at the edges of the top of the top plate 11, and guide rods 12 are slidably installed at the rod hole positions of the top plate 11. The bottom ends of the guide rods 12 are fixedly connected to the top of the bottom plate 15, and the top plate 11 is fixedly connected to the cavity assembly 2 through a connecting plate 5. When the molten material enters the forming assembly 1, the top plate 11 is connected to the cavity assembly 2 through the connecting plate 5. Notify that the guide pipe 307 is communicated with the cavity groove 13 at the top. The bottom of the bottom plate 15 is fixedly connected to the forming equipment. Fixed plates 14 are fixedly connected to the opposite surfaces of the bottom plate 15 and the top plate 11. Cavity grooves 13 are fixedly connected to the opposite surfaces of the fixed plates 14. The cavity grooves 13 are flush with the opposite surfaces of the fixed plates 14. Before injecting the material, the forming equipment drives the bottom plate 15 and the top plate 11 to approach each other, so that the fixed plates 14 are closely attached to each other, and the cavity grooves 13 on the upper and lower sides are attached to each other to form a cavity. After the material enters the cavity, the material will be shaped according to the shape of the cavity, and the material in the cavity will be cooled by the cooling system of the forming equipment, and the material will be cooled and formed, and the cavity groove 13 at the top is communicated with the bottom end of the guide pipe 307.

[0019] The third embodiment, on the basis of the first and second embodiments, please refer to Figures 5 to 6As shown in the figure, the cavity assembly 2 includes an outer cavity tube 201. A sealing block 203 is fixedly connected to the bottom of the outer cavity tube 201, and a front blocking block 208 is fixedly connected to the top of the outer cavity tube 201. An inner cavity tube 205 is fixedly connected between the sealing block 203 and the front blocking block 208. The inner cavity tube 205 is located inside the outer cavity tube 201. A connecting pipe 202 is fixedly connected to the outside of the outer cavity tube 201. The connecting pipes 202 are symmetrically installed along the central position of the outer cavity tube 201. The bottom of the sealing block 203 is fixedly connected to the top of the top plate 11 through a connecting plate 5. When the material is being conducted, the connecting pipe 202 in the cavity assembly 2 is connected to the hot water pipe, so that hot water enters from one of the connecting pipes 202, and the hot water flows into the gap between the outer cavity tube 201 and the inner cavity tube 205. Under the restriction of the blocking ring 204 and the front sealing ring 209, the hot water is conducted through the guiding of the spiral shape of the guiding plate 206 and flows out from the other connecting pipe 202. The heat of the hot water is transferred to the inside through the inner cavity tube 205 to perform heat preservation treatment on the molten material flowing inside. A blocking ring 204 and a front sealing ring 209 are installed between the outer cavity tube 201 and the inner cavity tube 205. The bottom of the blocking ring 204 is fixedly connected to the top of the sealing block 203. A guiding plate 206 is fixedly connected between the front sealing ring 209 and the blocking ring 204. The guiding plate 206 is a spiral metal plate.

[0020] The front sealing ring 209 and the blocking ring 204 tightly seal between the outer cavity tube 201 and the inner cavity tube 205. And an elastic sleeve 207 is fixedly connected between the front sealing ring 209 and the front blocking block 208. The elastic sleeve 207 is made of an elastic material. The inner wall of the inner cavity tube 205 is fixedly connected to the outside of the fixed sleeve 302. Air outlet holes 210 are evenly opened at the top of the outside of the outer cavity tube 201. During the process of introducing hot water, the water flow pressure impacts the blocking ring 204 and the front sealing ring 209 on both sides. When the water pressure is too high, since the blocking ring 204 is fixed by the sealing block 203, the pressure is transmitted to the elastic sleeve 207 through the front sealing ring 209, causing the elastic sleeve 207 to deform under the impact of the water pressure, so that the front sealing ring 209 slides between the outer cavity tube 201 and the inner cavity tube 205 to buffer the water pressure. And the air outlet holes 210 are located between the front blocking block 208 and the front sealing ring 209. And the top of the front blocking block 208 is fixedly connected to the bottom of the connecting ring 4.

[0021] During use, the worker installs the mold and the extrusion molding equipment, connects the connecting ring 4 to the extrusion head of the extruder, and fixes the molding assembly 1 to the equipment, so that the molten material extruded by the extruder is introduced into the molding assembly 1 through the material guiding assembly 3. At the same time, during the introduction process, the hot water pipe is connected to the cavity assembly 2 to keep the flowing molten material warm. After the molten material enters the molding assembly 1, it is cooled and shaped according to the cavity shape.

[0022] When guiding the extruded molten material through the material guiding component 3, the material enters through the space between the gasket ring 301 and the fixed sleeve 302, enabling the material to enter the interior of the hole cover 303. Meanwhile, under the extrusion pressure of the extruder, the material impacts the pressing block 308, causing the pressing block 308 to transmit the impact pressure to the elastic pad 310, deforming the elastic pad 310. The pressing block 308 slides on the outside of the connecting rod 309. At the same time, after the elastic pad 310 deforms, it generates a resilience force, enabling the pressing block 308 to cooperate with the extrusion pressure to squeeze the material entering the hole cover 303 in all directions, causing the material to enter the fixed tube 304 through the sleeve holes. Guided by the fixed tube 304, the material flows along the interior of the primary cavity tube 305 and the secondary cavity tube 306 towards the material guiding tube 307, and is diverted to the molding component 1 through the material guiding tube 307. Meanwhile, when the material passes through the secondary cavity tube 306, since the diameter of the secondary cavity tube 306 gradually decreases, the flowing material is squeezed inwards, reducing the gap between the materials and the air between the introduced materials.

[0023] When the material is being conducted, the communication pipe 202 in the cavity component 2 is connected to the hot water pipe, enabling hot water to enter through one of the communication pipes 202 and flow into the gap between the outer cavity tube 201 and the inner cavity tube 205. Restricted by the blocking ring 204 and the front sealing ring 209, the hot water is conducted through the self - helical guiding of the flow - guiding plate 206 and flows out through the other communication pipe 202. The heat of the hot water is transferred to the interior through the inner cavity tube 205 to insulate the molten material flowing inside. Meanwhile, during the process of introducing hot water, the water flow pressure impacts the blocking rings 204 and the front sealing ring 209 on both sides. When the water pressure is too high, since the blocking ring 204 is fixed by the sealing block 203, the pressure is transmitted to the elastic sleeve 207 through the front sealing ring 209, deforming the elastic sleeve 207 under the impact of the water pressure, causing the front sealing ring 209 to slide between the outer cavity tube 201 and the inner cavity tube 205 to buffer the water pressure.

[0024] When the molten material enters the molding component 1, the top plate 11 is connected to the cavity component 2 through the connecting plate 5, and it is notified that the material guiding tube 307 is connected to the cavity groove 13 at the top. Before injecting the material, the forming equipment drives the bottom plate 15 and the top plate 11 closer to each other, making the fixing plates 14 fit tightly, and the cavity grooves 13 on the upper and lower sides fit together to form a cavity. After the material enters the cavity, the material will be shaped according to the shape of the cavity, and the material in the cavity will be cooled by the cooling system of the forming equipment in the cavity to cool and form the material.

All other embodiments obtained by those of ordinary skill in the art and related fields based on the embodiments of the present invention without creative efforts shall fall within the scope of protection of the present invention.
