A rapid injection molding mold

Abstract

The present invention discloses a rapid injection molding mold, which relates to the technical field of automobile headlight injection molding molds. The rapid injection molding mold includes a base and a shell, wherein the top of the base is fixed with a shell, and the inner side of the shell is fixed with a cylinder. In order to facilitate demolding, when the movable mold drives the push block to contact the fixed plate, the push block drives the sleeve rod to move into the demolding column, so that the arc block squeezes the transmission block back and forth and moves downward. Through the cooperation of the sliding rod, the hinged rod, the connecting rod and the moving block, the knocking column can knock back and forth on the inner side of the movable module, so that the injection molded product adhered to the movable mold can be loosened by vibration knocking, thereby facilitating the demolding operation. When the sleeve rod continues to move, it can drive the demolding column to move, and the demolding operation is conveniently performed through the two groups of demolding columns.

[0002] Car lights are used to illuminate the road at night and to signal various vehicle movements. Car lights are generally divided into headlights, taillights, turn signals, etc. Injection molding is required to produce the lampshades.

[0003] Patent publication number CN213006208U relates to a mold for a lampshade for an automobile headlight, comprising a housing, a fixed mold, and a movable mold. The housing has a base plate at the bottom and an injection molding tube at the top. A first fixed plate is welded to the interior of the housing, the fixed mold is fixedly connected to the bottom surface of the first fixed plate, and the bottom of the injection molding tube is connected to the fixed mold. A second fixed plate is provided below the first fixed plate, fixedly connected to the inner sidewall of the housing, and a U-shaped connecting frame is slidably connected to the second fixed plate. A movable plate is welded to the top of the connecting frame, and four connecting columns are symmetrically welded to the top surface of the movable plate. The tops of the connecting columns are fixedly connected to the movable mold. The patent uses an electric push rod to control the overall lifting and lowering of the connecting frame, movable plate, connecting columns, and movable mold. Under the action of the second fixed plate, limit plate, and movable plate, the demolding rod and movable mold can produce relative displacement, thereby quickly ejecting the finished lampshade from the movable mold.

[0004] In the above patent, when the lampshade is demolded, some parts of the molded lampshade may stick to the movable mold after cooling. Therefore, when the lampshade is demolded directly by squeezing it through the demolding rod, the molded lampshade may be pulled, resulting in poor quality of the produced lampshade, which will affect the normal use of the lampshade in the future. Summary of the Invention

[0005] In view of the deficiencies in the prior art, the present invention provides a rapid injection molding die, which solves the problems raised in the above background technology.

[0006] To achieve the above objectives, the present invention is implemented through the following technical solutions: a rapid injection molding mold, including a base and a shell, the top of the base is fixed with the shell, the inner side of the shell is fixed with a cylinder, the left output end of the cylinder is fixed with a movable mold, the inner wall of the shell is fixed with a static mold, the left side of the static mold is fixed with an injection tube, and the left side of the shell is fixed with a controller.

When injection molding is completed, the movable mold is started to be controlled to move away from the static mold. When the movable mold drives the push block to contact the fixed plate, the push block will be subjected to extrusion force, causing the sleeve rod to move toward the demoulding column, thereby causing the sleeve rod to drive the arc block to move.

The end of the hinged rod away from the connecting rod is hinged on the sliding rod. When the arc block moves, the arc block and the top of the transmission block are squeezed. Due to the extrusion force on the transmission block, the transmission block will move downward, thereby driving the sliding rod to move downward, causing the sliding rod to squeeze the hinged rod, causing the hinged rod to squeeze the connecting rod to move, thereby causing the connecting rod to drive the moving block to move.

[0008] According to the above technical solution, the side wall of the moving block is fixed with multiple groups of knocking columns in a linear array, and the side wall of the knocking column is in contact with the inner side of the side wall of the movable mold. The side wall of the moving block is fixed with a return spring, and the side of the return spring away from the moving block is fixed to the inner side of the movable mold. When the moving block moves, the return spring is compressed, and the moving block drives the knocking column to move, so that the hinged column is away from the inner side of the side wall of the movable mold. When the sleeve rod squeezes the connecting spring to a complete state, when the sleeve rod continues to move, the connecting spring can squeeze the demolding column to move.

[0009] The L-shaped link is fixed to the side wall of the sliding plate, and the L-shaped link is fixed to the side wall of the sliding plate, so that the L-shaped link can move downwards.

When the positioning plate is subjected to extrusion force, the positioning plate will be close to the connecting seat, so that the connecting column can push the baffle to move, driving the L-shaped limiting rod to move out of the limiting hole, thereby releasing the fixation of the extrusion plate. By setting the torsion spring, the extrusion plate can be rotated.

[0012] According to the above technical solution, the control component includes a card block, a fixed spring, a baffle and a disc; the card block is slidably installed on the top inner side of the shell, and a baffle is slidably installed on the bottom of the card block, and the baffle passes through the opening of the extrusion plate.

When the extrusion plate rotates, the extrusion plate does not block the disc.

[0013] According to the above technical solution, a fixed spring is fixed to the bottom of the card block, and the fixed spring is fixed to the inner side of the top of the shell. The fixed spring is in a stretched state. When the disc is not blocked, the fixed spring is in a stretched state, thereby driving the card block to move downward, and the card block can be stuck into the button of the controller.

[0014] The present invention provides a rapid injection molding mold. It has the following beneficial effects:

[0015] 1. In order to facilitate demoulding, the rapid injection molding mold drives the push block to contact the fixed plate when the movable mold drives the push block to contact the fixed plate, which will cause the push block to drive the sleeve rod to move into the demoulding column, so that the arc block will squeeze the transmission block back and forth and move downward. Through the cooperation of the sliding rod, the hinged rod, the connecting rod and the moving block, the knocking column can knock the inner side of the movable module back and forth, so that the injection molded product adhered to the movable mold can be loosened by vibration knocking, which is helpful for the demoulding operation. When the sleeve rod continues to move, it can drive the demoulding column to move, and the demoulding operation is conveniently performed through two sets of demoulding columns.

[0016] 2. The rapid injection molding mold can drive the fixing rod to move when the demoulding column moves, and the C-shaped rod can be moved in the inclined groove section of the slide groove through the fixing block, so that the slide plate can be squeezed to move downward, driving the L-shaped connecting rod to move. Through the cooperation of the connecting seat and the connecting column, the two sets of positioning plates can be close to each other, so that the workpiece after demoulding can be centered through the positioning plate, which is convenient for the staff to pick up and can prevent the workpiece from falling off the mold and causing damage. During the injection molding operation, when the burr of the workpiece is too large, the positioning plate will be moved when the workpiece is centered, and the L-shaped limit rod can be moved out of the limit hole through the connecting column, so that the limit on the extrusion plate can be released. The workpiece can be pushed to the back of the equipment through the extrusion plate, thereby preventing the staff from taking it and serving as a reminder for the staff to repair the mold.

[0017] 3. The rapid injection molding mold can prevent the disc from being blocked when the extrusion plate rotates, and through the cooperation of the fixed spring, the fixed spring can drive the card block to move downward, so that the card block is stuck in the button of the controller, thereby preventing the staff from accidentally starting the dynamic mold.

The fixed plate 6 and the movable mold 4 are provided with a demoulding assembly for facilitating demoulding; wherein the demoulding assembly includes a demoulding column 9, a sleeve rod 10, a push block 11, a connecting spring 12, a return spring 13, a stop block 14, an arc block 15, a slide rod 16, a hinged rod 21, a connecting rod 20, a moving block 17, a return spring 18, a transmission block 19 and a knocking column 22; the demoulding column 9 is penetrated by the movable mold 4, and the penetration is slidably connected, the inner wall of the demoulding column 9 is slidably mounted with a sleeve rod 10, and one end of the sleeve rod 10 is fixed with a push block 11. The other end of the sleeve rod 10 is fixed with a connecting spring 12. The side of the connecting spring 12 away from the sleeve rod 10 is fixed to the inner wall of the demoulding column 9. The bottom of the sleeve rod 10 is fixed with multiple groups of arc blocks 15 in a linear array. The outer wall of the demoulding column 9 is fixed with a stopper 14. The side wall of the stopper 14 is fixed with a return spring 13. The side of the return spring 13 away from the stopper 14 is fixed to the side wall of the movable mold 4. The side wall of the movable mold 4 is slidably installed with a slide rod 16. The top of the slide rod 16 is fixed with a transmission block 19. A moving block 17 is slidably installed on the inner side of the tool 4, and a connecting rod 20 is fixed on the top of the moving block 17. A hinged rod 21 is hinged on the top of the connecting rod 20, and the end of the hinged rod 21 away from the connecting rod 20 is hinged on the slide rod 16. The side wall of the moving block 17 is fixed with multiple groups of knocking columns 22 in a linear array, and the side walls of the knocking columns 22 are in contact with the inner side of the side wall of the movable mold 4. A return spring 18 is fixed on the side wall of the moving block 17, and the side of the return spring 18 away from the moving block 17 is fixed to the inner side of the movable mold 4.

[0031] By setting up multiple groups of knocking columns 22, before performing the demoulding operation, the knocking columns 22 can be used to knock the inner side of the right side of the movable mold 4, so that the workpiece on the movable mold 4 can be knocked loose before demoulding, which facilitates the subsequent demoulding operation.

[0032] Two groups of demoulding columns 9 are provided, and the two groups of demoulding columns 9 are symmetrically arranged with the center line of the movable mold 4 in the vertical direction as the symmetry axis. The demoulding columns 9 can eject the workpiece on the movable mold 4, thereby enabling demoulding operations.

[0033] When the embodiment is working: when the injection molding operation is required, the switch button on the controller 8 is used to start the cylinder 3, so that the cylinder 3 drives the movable mold 4 to approach the static mold 5, so that the convex part of the movable mold 4 extends into the mold groove of the static mold 5, and the injection liquid is poured into the mold groove of the static mold 5 through the injection pipe 7, thereby starting the injection molding operation. After the injection molding, the movable mold 4 is driven to move to the right by the cylinder 3, so that the movable mold 4 drives the push block 11 to move. When the push block 11 moves When it comes into contact with the fixed plate 6, and when the push block 11 moves, the elastic coefficient of the return spring 13 is larger than the elastic coefficient of the connecting spring 12. Therefore, when the push block 11 is squeezed, the sleeve rod 10 will first move toward the demoulding column 9, compressing the connecting spring 12. When the sleeve rod 10 moves, the arc block 15 can squeeze the top arc of the transmission block 19. The elastic coefficient of the return spring 18 is smaller than the elastic coefficient of the connecting spring 12. When the transmission block 19 is squeezed, The transmission block 19 moves downward, causing the slide bar 16 to move downward, which enables the slide bar 16 to squeeze the hinge rod 21 and rotate at the hinge, thereby enabling the hinge rod 21 to squeeze the connecting rod 20 to move, thereby enabling the moving block 17 to drive the knocking column 22 away from the right inner side of the movable mold 4, causing the moving block 17 to squeeze the return spring 18 to stretch, and when the arc block 15 moves to no longer contact the top of the transmission block 19, because the return spring 18 is in a stretched state, the moving block 17 can drive the knocking column 22 toward the movable mold 4 moves on the right inner side and knocks the inner side of the movable mold 4, so that the workpiece adhered to the movable mold 4 can be knocked loose, and when the sleeve rod 10 continues to move, when the connecting spring 12 is compressed to the complete state, so that when the sleeve rod 10 continues to move, the sleeve rod 10 can squeeze the connecting spring 12 to move, and the connecting spring 12 drives the demoulding column 9 to move, so that the stopper 14 squeezes the return spring 13 to be compressed, and the demoulding column 9 can move from the left side of the movable mold 4, so that the demoulding operation can be performed.

[0034] And when the cylinder 3 drives the dynamic mold 4 to approach the static mold 5, it will drive the push block 11 away from the fixed plate 6. Since the sleeve rod 10 is not subjected to the extrusion force and the connecting spring 12 is in a compressed state, the sleeve rod 10 can be driven to move out of the demoulding column 9 for the reset operation. When the demoulding column 9 is not subjected to the extrusion force, the reset spring 13 is in a compressed state, and the demoulding column 9 can be reset by the reset spring 13 for the next demoulding operation.

[0035] See also Figures 1-10On the basis of the above embodiment, another embodiment of the present invention further includes a centering component and a control component, and the centering component includes a fixing rod 2301, a fixing block 2302, a C-shaped rod 2303, a slide plate 2304, a slide groove 2305, an L-shaped connecting rod 2306, a connecting seat 2307, a connecting column 2308, a baffle 2309, a positioning plate 2311, a transmission spring 2310, an L-shaped limiting rod 2312, a hinge seat 2313, an extrusion plate 2315, a torsion spring 2314 and a limiting Hole 2316; The fixed rod 2301 is fixed to the top of the demoulding column 9, the top of the fixed rod 2301 is fixed with a fixed block 2302, the side wall of the fixed block 2302 is fixed with a C-shaped rod 2303, and the right side of the movable mold 4 is slidably installed with a slide 2304, the slide 2304 is provided with a slide groove 2305, the C-shaped rod 2303 passes through the slide groove 2305, and the penetration is fitted, the side wall of the slide 2304 is fixed with an L-shaped connecting rod 2306, and the end of the L-shaped connecting rod 2306 is away from the slide 2304 A connecting seat 2307 is fixed, an L-shaped connecting rod 2306 passes through the movable mold 4, and the L-shaped connecting rod 2306 can move at the penetration point of the movable mold 4.

The side wall of the connecting seat 2307 is fixed with a hinge seat 2313, and the inner side of the hinge seat 2313 is rotatably installed with an extrusion plate 2315. The side wall of the extrusion plate 2315 is fixed with a torsion spring 2314, and the side of the torsion spring 2314 away from the extrusion plate 2315 is fixed to the inner side of the hinge seat 2313. A limiting hole 2316 is provided on the top of the extrusion plate 2315, and an L-shaped limiting rod 2312 is fixed to the side wall of the baffle 2309, and the outer wall of the L-shaped limiting rod 2312 is in contact with the inner side of the limiting hole 2316.

[0036] There are two groups of positioning plates 2311, and the two groups of positioning plates 2311 are symmetrically arranged with the center line of the movable mold 4 in the vertical direction as the symmetry axis. By bringing the two groups of positioning plates 2311 close to each other, the two groups of positioning plates 2311 can just fit with the workpiece demolded from the movable mold 4, so that the workpiece can be centered, making it convenient for the staff to pick up.

[0037] There are two groups of extrusion plates 2315, and the two groups of extrusion plates 2315 are symmetrically arranged with the center line of the movable mold 4 in the vertical direction as the symmetry axis. The extrusion plates 2315 can be used to extrude workpieces with relatively large burrs, and the rotation of the extrusion plates 2315 can prevent staff from taking problematic workpieces from the front of the equipment, and can remind staff to repair the mold.

[0038] The control component includes a card block 2401, a fixed spring 2402, a baffle 2403 and a disc 2404; the card block 2401 is slidably installed on the top inner side of the shell 2, and the baffle 2403 is slidably installed on the bottom of the card block 2401.

The bottom of the disc 2404 fits with the top of the extrusion plate 2315, and the bottom of the card block 2401 is fixed with a fixed spring 2402. The fixed spring 2402 is fixed to the top inner side of the shell 2. Through the setting of the card block 2401, when there is a problem with the mold, the card block 2401 can be stuck into the control switch button, so that the switch button cannot be pressed, so that the cylinder 3 will not start, preventing the mold from having problems and the movable mold 4 from starting, which will cause serious product accidents.

[0039] When this embodiment is working: when the demoulding column 9 is squeezed to perform the demoulding operation, the demoulding column 9 can drive the fixed rod 2301 to move, so that the fixed block 2302 drives the C-shaped rod 2303 to move in the slide groove 2305 of the slide plate 2304. When the C-shaped rod 2303 moves in the inclined groove section of the slide groove 2305, the slide plate 2304 is squeezed and moved downward, thereby driving the L-shaped connecting rod 2306 to move, and the L-shaped connecting rod 2306 drives the connecting seat 2307 and the connecting column 2308 to move, so that the two sets of positioning plates 2311 are close to each other, so that the two sets of positioning plates 2311 and the demoulding column 9 can be demoulded. The top and bottom of the workpiece are fitted with the two sets of positioning plates 2311, so that the positioning plates 2311 fit exactly with the workpiece, centering the workpiece and preventing the workpiece from falling during demoulding. When the mold is used for a long time, the burrs of the workpiece produced may be too large, so when the burrs of the workpiece produced are too large, the positioning plates 2311 and the workpiece will not fit together. When the two sets of positioning plates 2311 are close to each other, the positioning plates 2311 will squeeze the burrs of the workpiece, so that the positioning plates 2311 will be squeezed and moved toward the connecting seat 2307, so that the transmission spring 2307 is pressed. 310 is stretched, and the connecting column 2308 drives the baffle 2309 away from the connecting seat 2307, so that the baffle 2309 drives the L-shaped limiting rod 2312 to move upward, and the L-shaped limiting rod 2312 is moved out of the limiting hole 2316, which can release the limitation of the extrusion plate 2315. Since the torsion spring 2314 is originally in a contracted state, the torsion spring 2314 can drive the extrusion plate 2315 to rotate, so that the extrusion plate 2315 can extrude the workpiece with problems after demoulding, and through the rotation of the extrusion plate 2315, the place where the staff at the front of the equipment take the material can be blocked, thereby preventing the staff from taking the material, and can It is enough to remind the staff to repair the mold, and when the movable mold 4 drives the extrusion plate 2315 to move, the extrusion plate 2315 can squeeze the baffle 2403 to move, so that the extrusion plate 2315 drives the baffle 2403 to move at the bottom of the block 2401, and when the extrusion plate 2315 rotates, the extrusion plate 2315 can not squeeze the disc 2404, and because the fixed spring 2402 is in a stretched state, the fixed spring 2402 drives the block 2401 to move downward, so that the block 2401 is stuck in the switch button on the controller 8, so that the switch button cannot be pressed, so that the cylinder 3 will not start.

[0040] When the workpiece with problems is taken out, the positioning plate 2311 is not in an extruded state, and the transmission spring 2310 is in a stretched state, which causes the L-shaped limit rod 2312 to press against the outer wall of the extrusion plate 2315. By rotating the extrusion plate 2315 to reset, the extrusion plate 2315 and the connecting seat 2307 are in a horizontal state, the limit hole 2316 can be aligned with the L-shaped limit rod 2312. Since the transmission spring 2310 is in a stretched state, the L-shaped limit rod 2312 can be extended into the limit hole 2316. Since the center of the limit hole 2316 is aligned with the center of the rotation of the extrusion plate 2315, when the L-shaped limit rod 2312 is extended into the limit hole 2316, the extrusion plate 2315 is fixed so that the next extrusion operation can be carried out, and when the extrusion plate 2315 rotates upward, the notch of the extrusion plate 2315 will be aligned with the baffle 2403, so that the baffle 2403 will pass through the notch of the extrusion plate 2315, and when the extrusion plate 2315 rotates to contact the bottom of the disc 2404, the extrusion plate 2315 will squeeze the disc 2404 to move upward, so that the baffle 2403 can move upward, and the baffle 2403 drives the block 2401 to move upward, so that the fixing spring 2402 is stretched, so that the block 2401 does not jam the switch button on the controller 8, and when the extrusion plate 2315 is fixed, the disc 2404 can be fixed.

[0041] While embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions, and variations may be made to these embodiments without departing from the principles and spirit of the invention, and that the scope of the invention is defined by the appended claims and their equivalents.
