Description

Technical Field

[0001] The present invention relates to the technical field of injection molding equipment, in particular to an integrated plastic parts injection molding equipment. Background Art

[0002] Home appliance plastic parts are a type of plastic component primarily used in home appliance production. Depending on the assembly requirements, they can perform various functions, including cushioning, shock absorption, protection, and support. Plastic injection molding is typically used to ensure the quality of these parts after production.

[0003] However, this injection molding equipment has the following defects when used: 1. When existing injection molding equipment is performing injection molding on plastic products (including but not limited to: plastic accessories for household appliances), it is necessary to pour the plastic particles that have completed preliminary processing into the interior of the feeder, and transfer the plastic particles to the extrusion equipment through the feeder, and move the plastic colloid to the interior of the mold by melting and extrusion, and realize the injection molding of the plastic product inside the mold. However, when the plastic particles located in the feeder are moved to the interior of the extrusion equipment, the plastic particles located in the feeder channel are easily squeezed by each other and block the discharge port of the feeder, affecting the normal discharge of the plastic particles. At the same time, it is difficult for the feeder to control the uniformity of the plastic particle feeding and discharging, resulting in an increase in the number of empty bags inside the plastic colloid due to the small amount of plastic particles when the extrusion equipment extrudes and injects the plastic particles, affecting the quality of the product after injection molding; 2. When existing injection molding equipment pours plastic granules into the extrusion equipment and extrude the plastic (after melting) inside the extrusion equipment into the mold, due to the small size of the plastic granules and the plastic becoming a colloid through heating, the plastic (granules and colloid) can easily enter the gaps in the inner wall of the extrusion equipment during the extrusion transmission process, affecting the normal operation of the extrusion equipment and easily causing external gas to enter the interior of the extrusion equipment, affecting the quality of the injection molded product.

In the integrated plastic parts injection molding equipment, when the plastic parts are injection molded, the first driving source can be used to drive the spiral extrusion rod to rotate, so that the plastic particles outside the spiral extrusion rod can be extruded and mixed. At the same time, the rotational force generated by the first driving source during operation can also drive the first transmission belt and the rotating shaft to operate, so as to drive the material return rod to rotate continuously inside the L-shaped pipe, and achieve uniform loading operation through the material return spiral part (constituting the spiral rod) outside the material return rod, thereby ensuring the quality of the plastic parts after the injection molding is completed (few empty packages). In addition, the force of the rotating shaft can also drive the material rod connected to the screw rod to move horizontally (reciprocating) inside the L-shaped pipe, further reducing the probability of plastic particles being blocked inside the L-shaped pipe. Among them, the operation of driving the material return rod to rotate and move horizontally (reciprocating) will not cause conflict and interference, thereby ensuring the stable loading of plastic particles;‌ 2. In integrated plastic part injection molding equipment, the design of the outer spiral structure of the ejector rod allows plastic pellets fed into the inclined pipe to directly contact the outer surface of the ejector spiral. This tapered structure increases the contact area between the pellets and the ejector spiral, making it easier for the pellets to flow along the outer slope of the ejector spiral into the inclined pipe. The inclined inner wall of the inclined pipe also prevents pellets from becoming clogged on the sides of the ejector spiral, improving pellet feeding efficiency. 3. In the integrated plastic part injection molding device, the first inclined surface obliquely provided at the connecting portion of the extrusion portion and the extrusion channel and the vertical surface at the top of the first inclined surface can, on the one hand, reduce the area of ​​contact between the connecting portion of the extrusion portion and the extrusion channel and the plastic colloid, reduce the probability of the plastic colloid moving to the connecting portion of the extrusion portion and the extrusion channel due to the force during extrusion, reduce the heat loss inside the extrusion channel and the probability of external gas entering the extrusion channel, and on the other hand, when the extrusion portion and the extrusion channel are assembled through the outer protective sleeve, the extrusion portion and the extrusion channel are not easily misaligned, further reducing the width of the gap between the two, while ensuring the convenience of docking and assembly; 4. In the integrated plastic parts injection molding equipment, by providing a bent (concave) embedded block on the side of the plastic pellet feeding position and a sealing ring inside the embedded block, on the one hand, the probability of plastic pellets getting stuck at the output end of the first driving source or outside the spiral extrusion rod can be reduced; on the other hand, the structure of the embedded block has a longer heat conduction path, which effectively improves the heat retention rate and reduces the probability of heat loss, thereby ensuring the effect of heating and melting the plastic pellets.

[0020] The above working principle: When the plastic parts of household appliances are injection molded, the plastic particles are first automatically added to the interior of the feeding system 202 through the central air supply system, and the first driving source 201 drives the screw return assembly 206 to operate, so that the plastic particles located inside the feeding system 202 are evenly moved to the interior of the plastic extrusion assembly 203, thereby ensuring the uniformity of the plastic particles during loading. At the same time, when the first driving source 201 is in operation, it can synchronously drive the plastic extrusion assembly 203 to operate, extrude and heat the plastic located inside the plastic extrusion assembly 203, so that the plastic particles can be melted into a plastic colloid inside the plastic extrusion assembly 203, and transported to the interior of the plastic injection mold 30 for injection molding of plastic products. Among them, when the plastic parts are injection molded by the plastic injection mold 30, the plastic injection mold 30 can be replaced according to demand to meet the requirements of injection molding and production of different plastic parts.

[0021] In the present invention, the first driving source 201 is preferably a servo system, which is mainly used to drive the plastic extrusion assembly 203 to operate, and the specific driving mode is rotational driving. The top of the plastic extrusion assembly 203 is connected to multiple automatic pressure relief valves.

[0022] Specific reference Figure 5 and Figure 8The feeding system 202 includes: an upper base 2021 installed on the top of the first driving source 201; an inclined pipe 2022 arranged at the inner center of the upper base 2021; a feeder 2023 installed on the top of the upper base 2021 by screws and connected to the inclined pipe 2022; and an L-shaped pipe 2024 installed on the side of the upper base 2021 by screws and connected to the inclined pipe 2022.

[0023] In this solution, a screw stripping assembly 206 is provided inside the inclined pipe 2022 and the L-shaped pipe 2024, the L-shaped pipe 2024 is connected to the plastic extrusion assembly 203, and the feeder 2023 is connected to the central air supply system through screws, wherein a rotating shaft 205 is provided through the interior of the upper base 2021, and the rotating shaft 205 is provided at the bottom of the inclined pipe 2022 and the L-shaped pipe 2024.

[0024] In the integrated plastic parts injection molding equipment of the present invention, through the design of the inclined pipe 2022, the plastic particles transmitted to the inside of the feeder 2023 can be automatically discharged into the horizontal channel inside the L-shaped pipe 2024, and the screw return assembly 206 in the horizontal channel of the L-shaped pipe 2024 can be used to achieve uniform plastic particle transmission and loading operations.

[0025] Specific reference Figure 5 、 Figure 6 and Figure 7 The plastic extrusion assembly 203 includes: an inlet pipe 2031 installed on the side of the first driving source 201 by screws; an extrusion channel 2032 installed on the side of the inlet pipe 2031 by screws; a spiral extrusion rod 2033 movably arranged inside the extrusion channel 2032 and connected to the output end of the first driving source 201; a mixing part 2034 arranged outside the spiral extrusion rod 2033 and located on the side of the spiral part of the spiral extrusion rod 2033; a one-way valve 2035 installed at the port of the spiral extrusion rod 2033 and located on the side of the mixing part 2034, wherein the spiral extrusion rod 2033 is arranged on the side of the first transmission belt 204, the inlet pipe 2031 is connected to the L-shaped pipe 2024, the mixing part 2034 is arranged in a ring shape, and the one-way valve 2035 is arranged in a truncated cone shape on the side away from the spiral extrusion rod 2033.

[0026] In this solution, an outer protective sleeve 2036 is installed on the outer side of the bottom of the extrusion channel 2032 by screws, and an extrusion portion 2037 is installed on the inner side of the bottom of the outer protective sleeve 2036 by screws. The extrusion portion 2037 extends to the interior of the plastic injection mold 30, and the bottom of the extrusion portion 2037 is set to be a truncated cone with a narrow bottom and a wide top, wherein the structural shape of the inner wall of the extrusion portion 2037 matches the structural shape of the one-way valve 2035.

[0027] In the above solution, the outer protective sleeve 2036 can protect and seal the connected and assembled extrusion portion 2037 and the extrusion channel 2032, reduce the probability of external gas entering or internal heat loss, and improve the injection molding effect.

[0028] In the integrated plastic part injection molding device of the present invention, when the first drive source 201 is in operation, the screw extrusion rod 2033 connected to the outside of its output end by a shaft will rotate, and the screw extrusion rod 2033 is extruded through the spiral portion outside the screw extrusion rod 2033. The extruded plastic is mixed through the mixing section 2034 outside the screw extrusion rod 2033, thereby reducing the internal gaps in the plastic colloid and the probability of producing empty bags. Among them, the plastic colloid extruded and moved to one side of the one-way valve 2035 can be moved to the other side of the one-way valve 2035 through multiple one-way channels opened therein, thereby achieving one-way movement of the plastic colloid and ensuring the quality of the injection molded parts.

[0029] Specific reference Figure 6 A gas channel 20321 is opened at the eccentric position inside the extrusion channel 2032 and is located on the outside of the spiral extrusion rod 2033. The interior of the gas channel 20321 is connected to a gas pipeline 20322 extending to the outside. The gas pipeline 20322 is connected to the circulating air pump 20323. The circulating air pump 20323 is installed on the top of the equipment base 10, wherein the interior of the circulating air pump 20323 is provided with a heating system for heating the gas.

[0030] In the integrated plastic part injection molding device of the present invention, when the plastic particles are melted and extruded, the circulating air pump 20323 and the heating system inside it are started to operate, and the gas for heating the plastic particles is circulated and continuously heated, and is transmitted to the interior of the gas channel 20321 through the gas pipeline 20322, and the plastic particles set in the gas channel 20321 are continuously heated. While ensuring the heating effect, the contact area (gas and plastic particles) is increased, thereby improving the efficiency of heating the plastic particles.

[0031] Specific reference Figure 8 and Figure 9The screw-removing assembly 206 includes: a reciprocating screw 2061 installed at the bottom of the rotating shaft 205 and movably connected to the first driving source 201; a reciprocating slider 2062 connected to the outside of the reciprocating screw 2061 through a ball bearing; an upper connecting rod 2063 installed at the top of the reciprocating slider 2062; a material-removing rod 2064 rotatably connected to the side of the upper connecting rod 2063; a material-removing spiral portion 2065 arranged on the outside of the material-removing rod 2064 and rotatably arranged inside the L-shaped pipe 2024, wherein the bottom of the reciprocating slider 2062 is slidably connected to the top of the guide rod 20621, the guide rod 20621 is installed at the top of the first driving source 201, and the surface of the material-removing spiral portion 2065 is set to be conical.

[0032] In this solution, a horizontal groove 20641 is provided inside the material return rod 2064 located on the outer side of the upper base 2021, and the outer side of the material return rod 2064 is movably connected to a synchronous wheel through the horizontal groove 20641, and a second transmission belt 20642 is provided on the outer side of the synchronous wheel located outside the material return rod 2064, and the second transmission belt 20642 is movably set on the side of the upper base 2021, wherein the inner side of the second transmission belt 20642 is connected to the outer side of the rotating shaft 205 through the synchronous wheel.

[0033] In the integrated plastic part injection molding device of the present invention, when the first drive source 201 is in operation, the first transmission belt 204 and the rotating shaft 205, which are connected to the outside of the output shaft via a synchronous pulley, rotate, thereby driving the reciprocating screw 2061 connected to the side of the rotating shaft 205 to rotate. As the reciprocating screw 2061 rotates, it drives the reciprocating slider 2062, which is connected to the outside of the reciprocating slider via a ball bearing, to reciprocate (horizontally). It also drives the ejector rod 2064, which is mounted on the top of the reciprocating slider 2062 via an upper connecting rod 2063, to reciprocate (horizontally), thereby reducing the probability of plastic particles becoming stuck inside the L-shaped pipe 2024. Furthermore, as the rotating shaft 205 rotates, it drives the second transmission belt 20642, which is connected to the outside of the reciprocating slider via a synchronous pulley, to operate, allowing the ejector rod 2064, which is movably connected to the inside of the second transmission belt 20642 via the synchronous pulley, to rotate continuously, thereby achieving uniform loading of the plastic particles. At this time, the design of the horizontal groove 20641 on the outside of the material ejection rod 2064 ensures that the rotation and horizontal movement of the material ejection rod 2064 can be carried out synchronously without causing interference and conflict.

[0034] Specific reference Figure 10The plastic injection mold 30 includes: a lower mold base 301 installed on the top of the equipment base 10 by screws; an embedding port 302 opened inside the lower mold base 301 and matching the extrusion part 2037; a lower mold base 303 of the mold connected to the embedding port 302 and installed on the side of the lower mold base 301 by screws; an upper mold base 304 of the mold matching the lower mold base 303; an upper mold base 305 installed on the side of the upper mold base 304 by screws; a horizontal electric slider 306 installed on the bottom of the upper mold base 305 by screws; and a horizontal slide rail 307 arranged inside the horizontal electric slider 306, wherein the horizontal slide rail 307 is installed on the top of the equipment base 10 by screws, and the horizontal slide rail 307 is arranged on the side of the lower mold base 301.

[0035] In this solution, two metal protrusions 3051 are installed on the top of the upper mold base 305 by screws, and a horizontal rod 3052 is installed on the side of the metal protrusion 3051. The horizontal rod 3052 is set through the lower mold base 301.

[0036] In the above scheme, when the upper mold base 305 moves horizontally, the horizontal rod 3052 installed on its top through the metal protrusion 3051 will move horizontally on the top of the lower mold base 301, guiding the movement of the upper mold base 305, ensuring that the upper mold base 305 and the lower mold base 303 can be fitted and sealed together.

[0037] In the integrated plastic part injection molding apparatus of the present invention, as plastic colloid moves through the extruder 2037 into the interior of the lower mold base 303, the plastic part is automatically injection molded via the product mold groove provided between the lower mold base 303 and the upper mold base 304. Prior to completion of the injection molding process or before injection, the upper mold base 304 can be freely replaced according to the requirements of the injection molded product. The horizontal electric slider 306 moves horizontally along the outer side of the horizontal rail 307, driving the upper mold base 304 mounted on top of the slider 306 to move horizontally, automatically completing the opening, closing, and sealing operations.

[0038] In the present invention, a serpentine cooling pipe (through circulating coolant) is provided inside the upper mold base 304 of the mold, which can quickly cool and shape the plastic parts after injection molding.

[0039] Example 2 Based on the above embodiment, it was found during use that when the channel inside the extrusion channel 2032 is expanded by the outer protective sleeve 2036 and the extrusion portion 2037 to complete the pushing operation of the molten plastic inside, the molten plastic material is a colloid. On the one hand, it is easy for it to enter the interior of the outer protective sleeve 2036 through the gap at the connection between the extrusion portion 2037 and the extrusion channel 2032. On the other hand, external gas can also easily enter the interior of the extrusion channel 2032 through the gap between the outer protective sleeve 2036 and the connection between the extrusion portion 2037 and the extrusion channel 2032, thereby affecting the extrusion effect of the plastic material.

[0040] For this purpose, refer specifically to Figure 11 The bottom of the connecting portion between the extrusion portion 2037 and the extrusion channel 2032 is set as a first inclined surface 50, and the top of the connecting portion between the extrusion portion 2037 and the extrusion channel 2032 is set as a vertical surface 501, and the first inclined surface 50 and the vertical surface 501 are connected.

[0041] In the integrated plastic part injection molding apparatus of the present invention, the tilted angle of first bevel 50 effectively reduces the contact area between the molten plastic colloid and the joint gap (first bevel 50) when it is transferred to the interior of extrusion portion 2037, thereby reducing the probability of the plastic colloid entering the connection between extrusion portion 2037 and extrusion channel 2032. Furthermore, the vertical surface 501 at the top of first bevel 50 reduces the ingress of external air and internal heat loss, while also facilitating the assembly of extrusion portion 2037 and extrusion channel 2032, making it less likely for misalignment to occur.

[0042] Example 3 Based on the above embodiment, it was discovered during use that when plastic pellets pass through L-shaped conduit 2024 and reach the interior of inlet conduit 2031, to ensure effective melting and extrusion of the plastic pellets, they need to be pre-processed to produce smaller plastic pellets. However, smaller plastic pellets can easily enter the interior of the inlet conduit 2031 through the gap between the spiral extrusion rod 2033 and the inlet conduit 2031, widening the distance between the spiral extrusion rod 2033 and the inlet conduit 2031 and affecting the normal rotation and operation of the spiral extrusion rod 2033.

[0043] For this purpose, refer specifically to Figure 12The entry pipe 2031 is set as a left entry tank 60 and a right entry pipe 601 assembled by screws, and the connecting part of the left entry tank 60 and the right entry pipe 601 is provided with an embedded block 602, and the internal movability of the embedded block 602 is provided with a sealing ring 603 installed on the outside of the output end of the first driving source 201, wherein the right entry pipe 601 is installed on the side of the first driving source 201 by screws, and the internal movability of the right entry pipe 601 is connected to the first transmission belt 204 extending to the outside, and the extrusion channel 2032 is installed on the side of the left entry tank 60 by screws, and the top of the left entry tank 60 is connected to the L-shaped pipe 2024.

[0044] In the integrated plastic parts injection molding device of the present invention, the connection portion between the first driving source 201 and the spiral extrusion rod 2033 can be blocked by the concavely arranged embedded block 602 and the sealing ring 603 arranged on the inner side of the embedded block 602. On the one hand, the probability of plastic particles being blocked on the outside of the output end of the first driving source 201 can be reduced by bending the connection portion between the two. On the other hand, the bent connection portion has a longer heat conduction path, which improves the heat retention rate and reduces the probability of heat loss, thereby ensuring the effect of heating and melting the plastic particles.

[0045] Without limitation, any person skilled in the art who is familiar with the technical field can make equivalent replacements or changes based on the technical solutions and inventive concepts of the present invention within the technical scope disclosed by the present invention, and these changes should be covered by the protection scope of the present invention.
