Abstract
Description
Technical Field
[0001] The invention belongs to the technical field of double-color injection molds, in particular to a double-color high-pressure injection mold. Background Art
[0002] A two-color mold is a mold in which two plastic materials are injected on the same injection molding machine and molded in two steps, but the finished product is only ejected once. Generally, this molding process is also called double-material injection molding. It is usually completed by a set of molds and requires a special two-color injection molding machine. That is, the first raw material plastic is injected into the small hole of the mold using the injection equipment. When it is formed, it becomes the first plastic. Then the mold is rotated 180° and the second raw material plastic is injected using the same injection equipment. After the second plastic is formed, the final encapsulation work is carried out to complete a basic two-color injection molding work.
[0003] Chinese invention patent CN111452291B relates to a two-color injection mold, which includes a front mold and a rear mold arranged opposite to each other, and a sliding mechanism is arranged at the abutment position of the front mold and the rear mold. The sliding mechanism is arranged on two opposite sides of the two-color injection mold, and the sliding mechanism includes a first sliding assembly and a second sliding assembly arranged at intervals. The first sliding assembly and the second sliding assembly both include a locking block and an elastic member; the two-color injection mold has low injection efficiency and poor injection effect.
[0004] Chinese invention patent CN112829207B discloses a two-color injection mold, including a first slider, a second slider, a first inclined guide column, and a second inclined guide column, and also includes a first oil cylinder arranged on the outside of the first slider, and a second oil cylinder arranged on the outside of the second slider, and a first guide seat and a second guide seat are respectively provided on the side of the first slider close to the first oil cylinder and the side of the second slider close to the second oil cylinder; the two-color injection mold is difficult to operate and has low operating accuracy.
[0005] When the above two-color high-pressure injection mold is performing injection molding, the molten hard material or molten soft material for injection molding cannot be fully mixed and stirred at the movable mold core, and is easily accumulated on one side of the movable mold core, thereby reducing the subsequent injection molding quality.
[0006] When the molten hard material injection is completed and before the subsequent soft material injection is started, the finished product will rotate with the rotation of the movable mold core. During the rotation, the finished product will be affected by the centrifugal force and cause the finished product to shift, thereby reducing the accuracy and stability of the subsequent soft material injection.
[0007] At the same time, after the molten hard material is injected and the mold is opened, the finished product will shrink due to the principle of thermal expansion and contraction due to the decrease in external ambient temperature, which will easily affect the injection volume of the subsequent molten soft material and ultimately affect the quality of the finished product.
[0008] After the soft material injection molding is completed, injection impurities are likely to remain on the outer surface of the movable mold core. If the impurities cannot be quickly cleaned, the subsequent injection molding quality will be affected. Summary of the invention

A plurality of connecting holes 4046 are evenly provided on one side of the annular groove 4042, and the other end of the connecting hole 4046 is connected to the side groove 4048, so that the gas inside the connecting hole 4046 can circulate with the inside of the side groove 4048, and the inside of the connecting hole 4046 is sealed and slidably connected with a vertical rod 4045, and the outer surface of the vertical rod 4045 and the inner wall of the connecting hole 4046 are sealed with each other, and the other end of the vertical rod 4045 is fixedly connected to the side wall of the ejection block 4043, so when the vertical rod 4045 moves up and down inside the connecting hole 4046, the vertical rod 4045 synchronously drives the ejection block 4043 to move up and down inside the annular groove 4042, and the annular groove The inner wall of 4042 is evenly provided with a plurality of connecting springs 4044, the other side of which is fixedly connected to the side wall of the ejection block 4043, the connecting spring 4044 is located on the outer surface of the vertical rod 4045, the setting of the connecting spring 4044 further improves the elastic reset performance of the ejection block 4043, the surrounding side surface of the connecting hole 4046 is evenly provided with a plurality of side row holes 4047, the other end of the side row holes 4047 passes through the core block 4041 and is connected to the upper side wall of the annular groove 4042, when the ejection block 4043 is freed from the blockage of the side row holes 4047, the side row holes 4047 connect the connecting hole 4046 and the annular groove 4042, thereby achieving the clamping and fixing of the finished product and the wind cleaning effect on the outer surface of the core block 4041.
[0055] The internal sealing sliding connection of the side groove 4048 is provided with a magnetic sealing block 40411, and the magnetic sealing block 40411 fits with the inner wall of the side groove 4048. When the magnetic sealing block 40411 moves inside the side groove 4048, the internal air pressure value of the side groove 4048 is changed synchronously. The other end of the magnetic sealing block 40411 is provided with a blocking column 40413 through a connecting rod 40412. The blocking column 40413 can clamp and fix the finished product and adjust the position of the finished product, and at the same time can achieve the cleaning effect on the outer surface of the core block 4041. The other end of the blocking column 40413 is provided with a pressure sensor 40415, and the pressure sensor 40415 is used to detect the pressure value at the end of the blocking column 40413.
[0056] One side of the core block 4041 is fixedly connected to the side wall of the forming groove 403, and the other side of the core block 4041 is provided with a protruding block 40417. The setting of the protruding block 40417 realizes the hollowness inside the finished product. The inner wall of the side groove 4048 is provided with an electromagnetic block 4049, and the other end of the electromagnetic block 4049 is provided with a reset spring 40410. The other end of the reset spring 40410 is fixedly connected to the side wall of the magnetic sealing block 40411. The setting of the reset spring 40410 realizes the elastic reset performance of the magnetic sealing block 40411. The magnetism of the end faces facing the electromagnetic block 4049 and the magnetic sealing block 40411 is the same. When the current of the electromagnetic block 4049 increases, the magnetic repulsion of the electromagnetic block 4049 on the magnetic sealing block 40411 increases, and the magnetic sealing block 40411 slides in a sealed manner inside the side groove 4048. The inner wall of the side groove 4048 A sealing ring 40416 is provided at the end, and the inner wall of the sealing ring 40416 is sealingly and slidably connected to the outer surface of the blocking column 40413. The setting of the sealing ring 40416 can ensure the sealing between the blocking column 40413 and the sealing ring 40416 when the blocking column 40413 moves. The diameter value of the blocking column 40413 is greater than the diameter value of the connecting rod 40412. When the blocking column 40413 continuously moves outward and separates from the sealing ring 40416, the side groove 4048 is connected to the outside world, and the wind cleaning performance of the outer surface of the core block 4041 is further realized. The side wall of the blocking column 40413 is provided with an inner groove 40414, and the inner groove 40414 matches the outer surface of the pressure sensor 40415. The setting of the inner groove 40414 ensures the flatness and smoothness of the outer surface of the pressure sensor 40415 and the blocking column 40413, thereby correspondingly improving the quality of the finished product.
[0057] Two finished structures 5 are symmetrically arranged inside the movable mold structure 4, and the finished structure 5 includes an inner shell 501, and the peripheral side surfaces of the inner shell 501 respectively match the side walls of the first static mold plate 205, the molding groove 403 and the adjusting component 4, so that the molten hard material is injected between the first static mold plate 205 and the movable mold structure 4 to form the inner shell 501, and an inner hole 502 is arranged inside the inner shell 501, and the inner wall of the inner hole 502 matches the outer surface of the protruding block 40417, and the setting of the protruding block 40417 forms the inner hole 502 structure, and an outer shell 503 is arranged on one side of the inner shell 501, and the peripheral side surfaces of the outer shell 503 respectively match the side walls of the second static mold plate 305, the molding groove 403 and the adjusting component 404, and the soft material forms the outer shell 503 between the second static mold plate 305 and the movable mold structure 4, thereby finally forming the desired finished structure 5.
[0058] When the two-color high-pressure injection mold is performing injection molding, the molten hard material or molten soft material used for injection molding cannot be fully mixed and stirred at the movable mold core 402, and is easily accumulated on one side of the movable mold core 402, thereby reducing the quality of subsequent injection molding; when the injection molding of the molten hard material is completed and before the subsequent soft material injection molding is performed, the finished product will rotate with the rotation of the movable mold core 402. During the rotation, the finished product will be subjected to centrifugal force and cause the finished product to shift, thereby reducing the accuracy and stability of the subsequent soft material injection molding; and after the injection molding of the molten hard material is completed and the mold is opened, the movable mold core 402 drives the finished product to rotate. Due to the reduction of the external environment, the finished product will shrink under the principle of its own thermal expansion and contraction, which is easy to affect the injection amount of the subsequent soft material during the subsequent soft material injection molding, and ultimately affect the quality of the finished product; when the soft material injection molding is completed, injection impurities are likely to remain on the outer surface of the movable mold core 402. If the impurities cannot be quickly cleaned, the subsequent injection molding quality will be affected.
[0059] In order to solve the above problems, when the two-color high-pressure injection mold is actually used, the movable plate 103 moves along the limit rod 102 to the end close to the fixed plate 101. At this time, the two movable mold structures 4 are tightly closed with the first static mold structure 2 and the second static mold structure 3, respectively, wherein the multiple first plug rods 208 and the second plug rods 308 are respectively plugged and fixed with the multiple plug holes 422 inside the two movable mold modules 401, and the first static mold plate 205 and the second static mold plate 305 are respectively matched with the two movable mold modules 401, and then the injection molding process is carried out simultaneously, and in the initial state, the power-on current of the electromagnetic block 4049 is at the initial value, and the electromagnetic block 4049 is connected to the magnetic sealing block 40 The magnetic repulsion force applied by 411 drives the magnetic sealing block 40411 to stretch the reset spring 40410 and is in the initial position. The magnetic sealing block 40411 drives the blocking column 40413 to be in the initial position through the connecting rod 40412. At the same time, the internal gas of the side groove 4048 enters the connecting hole 4046 and applies a thrust to the end of the vertical rod 4045. The other end of the vertical rod 4045 drives the ejection block 4043 to move along the annular groove 4042 to the initial value. The ejection block 4043 blocks multiple side row holes 4047, and the ends of the ejection block 4043 and the blocking column 40413 match the side walls of the core block 4041, and the core block 4041 is a complete and smooth structure.
[0060] Then, the molten hard material is introduced into the first injection tube 202 along the injection hole 107. The molten hard material reaches the first static mold plate 205, the area between the core block 4041 and the molding groove 403 under the spraying action of the first high-pressure nozzle 204 and the first guide tube 206. At the same time, the heat medium is introduced into the first heat flow tube 207 to improve the fluidity and stability of the molten hard material. Then, the current of the electromagnetic block 4049 changes continuously. The magnetic repulsion applied by the electromagnetic block 4049 to the magnetic sealing block 40411 The magnetic sealing block 40411 is driven to reciprocate inside the side groove 4048 by the force and the elastic force of the return spring 40410. The magnetic sealing block 40411 drives the blocking column 40413 to reciprocate along the sealing ring 40416 through the connecting rod 40412. The blocking column 40413 reciprocates and vibrates the molten hard material, further improving the fluidity and stability of the molten hard material between the core block 4041 and the first static mold plate 205, thereby avoiding the long-term accumulation of the molten hard material and affecting the injection molding quality.
[0061] At the same time, when the magnetic sealing block 40411 moves back and forth inside the side groove 4048, the force exerted by the magnetic sealing block 40411 on the gas inside the side groove 4048 changes, and the gas inside the side groove 4048 continuously reciprocates along the connecting hole 4046. The air pressure inside the connecting hole 4046 continuously changes and the thrust exerted on the side wall of the vertical rod 4045 changes. Under the action of the air pressure thrust, the vertical rod 4045 drives the ejection block 4043 to stretch the connecting spring 4044 and reciprocate along the annular groove 4042. The ejection block 4043 exerts a reciprocating vibration force on the molten hard material between the core block 4041 and the molding groove 403, thereby further improving the fluidity and uniformity of the molten hard material.
[0062] Afterwards, the ejection block 4043 and the blocking column 40413 stop vibrating the molten hard material. If the molten hard material is evenly distributed, the pressure values detected by the multiple pressure sensors 40415 are all the preset pressure values. When the molten hard material accumulates on one side of the core block 4041, the pressure value applied by the molten hard material to the pressure sensor 40415 at the end of the blocking column 40413 increases, and the pressure value detected by the pressure sensor 40415 increases, while the pressure values detected by the pressure sensors 40415 at other positions decrease. Then, the current of the electromagnetic block 4049 at the end where the pressure value detected by the pressure sensor 40415 increases, and the magnetic repulsion force applied by the electromagnetic block 4049 to the magnetic sealing block 40411 increases, driving the magnetic sealing block 40411 to stretch the reset spring 40410 and move away from the end of the electromagnetic block 4049. The magnetic sealing block 40411 drives the blocking column 40413 to move outward through the connecting rod 40412.
[0063] And because the magnetic sealing block 40411 moves and applies an extrusion pressure to the internal gas of the side groove 4048, the internal gas of the side groove 4048 enters the connecting hole 4046 and increases the thrust applied to the end of the vertical rod 4045, and the vertical rod 4045 drives the ejection block 4043 along the connecting hole 4046 to stretch the connecting spring 4044 to move outward, then the thrust applied by the ejection block 4043 and the blocking column 40413 to the molten hard material increases, and the molten hard material moves around under the action of the extrusion pressure, thereby causing the pressure values detected by the other multiple pressure sensors 40415 to continuously increase to the set pressure preset value, ensuring that the harder raw material is evenly distributed between the first static mold plate 205, the molding groove 403 and the core block 4041, thereby improving the fluidity and uniformity of the molten hard material, and the end of the protruding block 40417 contacts the side wall of the first static mold plate 205, then an inner hole 502 is formed at the center of the inner shell 501.
[0064] After the molten hard material is injected and the inner shell 501 is formed, the inner shell 501 is attached to the outer surface of the core block 4041, and the movable plate 103 moves in the opposite direction along the limit rod 102 to the maximum distance, and then the movable plate 103 synchronously drives the two movable mold structures 4 to move in the opposite direction, and the two movable mold structures 4 are molded with the first static mold structure 2 or the second static mold structure 3. After the mold separation is completed, the rotating disk 105 rotates and drives the two movable mold structures 4 to rotate synchronously, and the movable mold structure 4 drives the inner shell 501 to rotate, and during the rotation During the process, in order to prevent the inner shell 501 from separating from the movable mold structure 4 under the action of centrifugal force, the current of the electromagnetic block 4049 continues to decrease, and the magnetic repulsion force exerted by the electromagnetic block 4049 on the magnetic sealing block 40411 decreases. Under the elastic force of the reset spring 40410, the magnetic sealing block 40411 continues to move toward the end of the electromagnetic block 4049, and the magnetic sealing block 40411 drives the blocking column 40413 to move away from the end of the inner shell 501 through the connecting rod 40412.
[0065] At the same time, since the internal volume of the side groove 4048 increases and the air pressure decreases, the gas in the connecting hole 4046 enters the side groove 4048, and the interior of the connecting hole 4046 is subjected to negative pressure, and the ejector block 4043 is driven to move inward along the annular groove 4042 under the elastic force of the connecting spring 4044, and the ejector block 4043 is separated from the blockage of the opposite side row holes 4047, and a suction force is applied to the multiple side row holes 4047 under the negative pressure of the connecting hole 4046, and the other end of the side row holes 4047 applies a suction force to the inner wall of the inner shell 501 through the annular groove 4042, thereby further improving the adsorption effect of the inner shell 501 on the outer surface of the core block 4041, and preventing the moving module 401 from driving the inner shell 501 to rotate when the rotating disk 105 rotates, and preventing the inner shell 501 from being separated from the core block 4041 under the centrifugal force on the inner shell 501 itself, thereby affecting the subsequent soft material injection molding accuracy.
[0066] When the rotating disk 105 rotates 180 degrees and drives the two movable mold structures 4 to rotate synchronously, the inner shell 501 end moves to match the second static mold structure 3, the current of the electromagnetic block 4049 increases and returns to the initial value, then the magnetic sealing block 40411 synchronously returns to the initial value, the blocking column 40413 and the ejection block 4043 are at the initial value and match the outer surface of the core block 4041.
[0067] At this time, if the external ambient temperature is too low, the inner shell 501 will shrink synchronously according to the principle of its own thermal expansion and contraction, and the pressure value applied by the inner shell 501 to the multiple pressure sensors 40415 will increase. Then, the pressure values detected by the multiple pressure sensors 40415 will increase and be greater than the set pressure preset value. At this time, if soft material injection molding is performed directly, there will be a gap between the side surfaces of the inner shell 501 and the molding groove 403 and the second static mold plate 305, which may easily cause damage to the subsequent injection molding of the outer shell 503.
[0068] The current of the electromagnetic block 4049 increases and the magnetic repulsion force exerted on the magnetic sealing block 40411 increases. The magnetic sealing block 40411 stretches the reset spring 40410 to move away from the end of the electromagnetic block 4049. The magnetic sealing block 40411 drives the blocking column 40413 to move outward through the connecting rod 40412. The blocking column 40413 applies a thrust to the inner wall of the inner shell 501 and moves the inner shell 501 to the initial distance. At the same time, the gas inside the side groove 4048 enters the connecting hole 4046 and applies a thrust to the end of the vertical rod 4045. The other end of the vertical rod 4045 drives the ejection block 4043 to stretch the connecting spring 4044 to move outward. The ejection block 4043 applies a thrust to the inner wall of the inner shell 501 and makes the other end of the inner shell 501 fit with the inner wall of the molding groove 403, thereby ensuring the accurate position of the inner shell 501 and improving the subsequent injection molding quality of the molten soft material.
[0069] The above process is then repeated, the movable plate 103 moves toward the end close to the fixed plate 101, the movable module 401 fits tightly against the second static mold plate 305, the molten soft material is introduced into the second injection tube 302 along the injection hole 107, the molten soft material is ejected along the second high-pressure nozzle 304 and the second guide tube 306, the heat medium is introduced into the second heat flow tube 307, and the above process is repeated to perform injection molding on the molten soft material, thereby forming an outer shell 503 on the outer surface of the inner shell 501.
[0070] After the processing of the finished product structure 5 is completed, the movable plate 103 moves in the reverse direction to the initial position, and the movable plate 103 drives the movable mold structure 4 to move in the reverse direction to the initial position through the rotating disk 105, and the movable mold structure 4 drives the multiple finished product structures 5 inside to move in the reverse direction to the initial position. At this time, the rotating screw 420 matched with the second static mold structure 3 rotates forward and drives the threaded ring 421 to move horizontally, and the threaded ring 421 drives the ejector plate 406 to move, and the ejector plate 406 drives multiple ejector pins 407 to move along the ejection hole 426, and the ejector pins 407 eject the finished product structure 5. At the same time, during the ejection process, the electromagnetic block The current flowing through 4049 decreases, and the elastic force of the reset spring 40410 drives the magnetic sealing block 40411 to move toward the end of the electromagnetic block 4049. The magnetic sealing block 40411 drives the blocking column 40413 to move through the connecting rod 40412, and the end of the blocking column 40413 is separated from the inner wall of the inner shell 501. At the same time, the side groove 4048 applies a suction force to the vertical rod 4045 inside the connecting hole 4046 under the action of negative pressure, and the vertical rod 4045 drives the ejection block 4043 to move inward along the annular groove 4042, and the end of the ejection block 4043 is separated from the inner wall of the inner shell 501.
[0071] Afterwards, the current flowing through the electromagnetic block 4049 increases, and the electromagnetic block 4049 applies magnetic repulsion to the magnetic sealing block 40411 and drives the magnetic sealing block 40411 to stretch the reset spring 40410 and move away from the end of the electromagnetic block 4049, and the magnetic sealing block 40411 drives the blocking column 40413 to move through the connecting rod 40412, and the blocking column 40413 applies thrust to the inner wall of the inner shell 501 and cooperates with the ejector pin 407 to increase the demoulding speed of the inner shell 501, and at the same time, the gas inside the side groove 4048 applies thrust to the end of the vertical rod 4045 inside the connecting hole 4046, and the other end of the vertical rod 4045 drives the ejection block 4043 to stretch the connecting spring 4044 and move outward, and the ejection block 4043 applies thrust to the inner wall of the inner shell 501, so that the inner wall of the inner shell 501 is quickly separated from the outer surface of the core block 4041, thereby improving the demoulding efficiency of the inner shell 501.
[0072] After demoulding is completed, the current of the electromagnetic block 4049 reaches the maximum value, the electromagnetic block 4049 exerts a magnetic repulsion force on the magnetic sealing block 40411 to the maximum value, the magnetic sealing block 40411 stretches the reset spring 40410 to move to the maximum value away from the electromagnetic block 4049, and the magnetic sealing block 40411 drives the blocking column 40413 to move to the maximum value through the connecting rod 40412, and the blocking column 40413 is separated from the sealing ring 40416. At the same time, the gas inside the side groove 4048 exerts a thrust on the end of the vertical rod 4045 inside the connecting hole 4046 to reach the maximum value, and the other end of the vertical rod 4045 drives the ejection block 4043 to stretch the connecting spring 4044 to move outward to the maximum value, and the ejection block 4043 is separated from the annular groove 4042, but since the vertical rod 4045 is still moving inside the connecting hole 4046, part of the gas inside the side groove 4048 is discharged along the end of the side groove 4048 under the thrust of the magnetic sealing block 4041, thereby achieving the wind cleaning effect on the end of the core block 4041, and another part of the gas inside the side groove 4048 enters the inside of the multiple side row holes 4047 along the connecting hole 4046, and is discharged to the annular groove 4042 along the other end of the side row holes 4047, and finally is discharged to the inside of the molding groove 403 along the annular groove 4042, thereby achieving the wind cleaning effect on the inner wall of the molding groove 403, improving the cleaning efficiency, ensuring the cleaning effect, and avoiding affecting the subsequent two-color high-pressure injection molding.
[0073] Afterwards, the rotating disk 105 continues to rotate 180 degrees and repeats the above process to continuously perform the two-color high-pressure injection molding process.
