Description
Technical Field
[0001] This invention relates to the field of automotive deflector forming equipment, and more particularly to an integrated automotive deflector forming equipment. Background Technology
[0002] The integrated injection mold for the car diffuser consists of a moving mold and a fixed mold. The fixed mold has a molded core on its surface. The injection cavity of the car diffuser is constructed by the closing of the moving mold and the fixed mold. After injection molding, the moving mold moves and separates from the fixed mold. At this time, the molded diffuser is attached to the mold core of the fixed mold. The diffuser is pushed off the mold core by the ejector pin integrated in the fixed mold.
[0003] Currently, the injection molding of automotive air deflectors is only achieved by using ejector pins distributed at multiple points. Due to the complex curved structure of automotive air deflectors, the contact area between them and the mold core is large and the adhesion is extremely uneven. Simply pushing the material out with ejector pins can easily cause defects such as warping, deformation, and cracking in the air deflector. Summary of the Invention
[0004] To overcome the shortcomings of existing technologies, the purpose of this invention is to provide an integrated molding equipment for automotive deflectors, which is used to grade and separate the injection-molded automotive deflectors for material discharge, thereby reducing the deformation stress during material discharge and preventing damage to the automotive deflectors during material discharge.
[0005] To address the problems of the prior art, the technical solution of the present invention is as follows: An integrated molding device for an automotive air deflector includes a mold base with a protruding mold core on its surface. Multiple split modules and an ejector module are slidably inserted into the surface of the mold core. The split modules, ejector module, and mold core close together to form the injection molding surface of the automotive air deflector. A linkage component is connected to the rear of each split module, and a pusher component is connected to the rear of each ejector module. A rocker plate rotates at the rear of the mold core, with one end of the rocker plate inclined towards the linkage component and the other end abutting against the pusher component. A hydraulic cylinder is installed inside the mold base, connected to the linkage component. The hydraulic cylinder drives the linkage component to move the split modules backward, and the linkage component abuts against the rocker plate, causing the rocker plate to press against the pusher component and move the ejector module forward.
[0006] Preferably, the pusher includes a panel, and a push rod is fixed to the rear of each ejector module. The rear ends of the push rods are converged and fixedly connected to the panel. The rocker plate abuts against the rear of the panel, and a compression spring is connected between the panel and the mold core.
[0007] Preferably, the split modules are located in the middle of the mold core, and the ejection modules are located at the edges of the mold core.
[0008] Preferably, the linkage includes a strip block, and a sliding cavity is provided at the rear of the mold core. The strip block is adapted to slide into the sliding cavity. The split module is connected to the strip block. Angle plates rotate symmetrically inside the strip block. The front of the angle plate has a positioning block. The inner wall of the sliding cavity has a positioning groove. The two angle plates are supported and expanded by a spring, so that the positioning block is inserted into the positioning groove. A shaft is slidably inserted inside the strip block. One end of the shaft is fixed with an expanding block, and the other end is connected to the hydraulic cylinder. When the hydraulic cylinder drives the shaft and the expanding block to retract, the expanding block presses against the rear of the angle plate and expands, so that the positioning block at the front end of the angle plate moves closer to and separates from the positioning groove. The end of the positioning block is spherical.
[0009] Preferably, the split module is divided into a fixed module and a moving module. The fixed module is fixedly connected to the strip block, and the rear end of the moving module is fixed with a card seat with increased width. The surface of the strip block is provided with a card slot, and the card seat is adapted to be inserted into the card slot. The card seat has guide blocks on both sides, and the card slot has guide grooves on both sides. The guide blocks and guide grooves are slidably connected. A compression spring is connected between the card seat and the card slot. The fixed module and the moving module are distributed alternately.
[0010] Preferably, there is a gap between the end of the rocker and the strip, so that the strip moves the driving module backward before pressing against the rocker and twisting. There are two rockers that are symmetrically rotated.
[0011] Preferably, a pressure sensor is provided on the front surface of the strip.
[0012] Compared with the prior art, the advantages of the present invention are as follows: 1. This invention constructs the injection molding surface of an automotive air deflector by slidingly inserting multiple separate modules and multiple ejection modules onto the surface of the mold core. A hydraulic cylinder drives a linkage component to pre-separate the separate modules from the air deflector. Then, the linkage component retracts to abut against a rocker plate, causing the rocker plate to twist forward and press against a pusher component. The pusher component pushes the ejection module forward to push the air deflector, causing the air deflector to separate and detach from the mold core. This staged separation method reduces the adhesive stress of the air deflector and avoids damage to the automotive air deflector during demolding.
[0013] 2. The present invention divides the split module into a fixed module and a moving module. The fixed module is directly fixed to the linkage component, and the moving module is movably connected to the linkage component. During the demolding process, the fixed module separates from the guide plate first, and the moving module separates from the guide plate later. Finally, the ejection module pushes the guide plate off. The entire demolding process is divided into three stages, which further reduces the stress intensity during the demolding process.
[0014] 3. This invention uses a positioning block and a positioning groove to fix the linkage component in the sliding cavity, ensuring that the split module and the mold core are precisely matched to form the injection molding surface. During demolding, the hydraulic cylinder retracts, driving the shaft column and the expansion block to retract. The expansion block presses against the rear of the corner plate and expands, causing the positioning block at the front end of the corner plate to move closer to and separate from the positioning groove, thus automatically releasing the positioning of the linkage component. The hydraulic cylinder continues to drive the shaft column to retract, and through the expansion block pressing against the strip, the split module retracts and separates from the middle part of the guide plate, conveniently realizing the positioning and release.

[0024] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments.
[0025] An integrated molding equipment for automotive air deflectors includes a mold base 1, which is a fixed mold in an injection mold and is adapted to be a moving mold. This is existing technology, and the loading of the mold base 1 and the related structure of the moving mold will not be described in detail here.
[0026] like Figure 1 , Figure 8 As shown, the mold base 1 has a protruding mold core 2 on its surface. Multiple split modules 21 are slidably inserted into the middle of the surface of the mold core 2. Multiple telescopic grooves 25 are opened along the edge of the surface of the mold core 2. A material ejection module 22 is slidably inserted into each telescopic groove 25. The split modules 21, the material ejection module 22 and the mold core 2 close together to form the injection molding surface of the car guide plate.
[0027] like Figure 2 , Figure 3 As shown, the rear of the mold base 1 has a cavity, the rear of the mold core 2 extends into the cavity, the rear of the split module 21 slides through the mold core 2 and is connected to the linkage 6, the rear of the ejection module 22 is connected to the pusher 5, two rocker plates 4 are symmetrically rotated and installed at the rear of the mold core 2, the two rocker plates 4 are distributed in a V shape, one end of the rocker plate 4 is inclined towards the linkage 6, and the other end abuts against the pusher 5, a hydraulic cylinder 3 is installed in the cavity of the mold base 1, and the extension end of the hydraulic cylinder 3 is connected to the linkage 6.
[0028] The demolding process of the car spoiler after one-piece injection molding is as follows: The hydraulic cylinder 3 is activated and retracts, causing the linkage 6 to retract, so that the split module 21 is separated from the guide plate in advance. As the linkage 6 retracts, it abuts against the rocker plate 4, causing the rocker plate 4 to twist forward and press against the pusher 5. The pusher 5 pushes the ejection module 22 forward and pushes the guide plate, so that the guide plate separates and falls off from the mold core 2, and the car guide plate is demolded in a graded separation manner.
[0029] like Figure 7 As shown, the ejector 5 includes a panel 51. Each ejector module 22 has a ejector rod 52 fixed to its rear. The rear end of the ejector rod 52 slides through the mold core 2 and is fixedly connected to the panel 51. The rocker plate 4 abuts against the rear of the panel 51. A compression spring is connected between the panel 51 and the mold core 2. The compression spring applies pressure to the panel 51 to make it retract. Through the pulling of the ejector rod 52, the ejector module 22 is adapted to be inserted into the telescopic groove 25, keeping the front end of the ejector module 22 and the front end face of the mold core 2 to form a completed injection surface. When the guide plate is demolded, the twisted rocker plate 4 presses against the ejector 5, causing the ejector 5 to overcome the elastic force and drive the ejector rod 52 to move forward. The ejector rod 52 pushes the ejector module 22 forward and protrudes from the surface of the mold core 2, so that the ejector module 22 pushes the guide plate to demold.
[0030] The split module 21 is distributed in the middle of the mold core 2. The split module 21 pre-separates the adhesive part in the middle of the guide plate, reduces the adhesive force in the middle of the guide plate, and concentrates the adhesive stress between the guide plate and the mold core 2 at the edge. The ejection module 22 is distributed at the edge of the mold core 2, so that the ejection module 22 can stably push the guide plate to demold.
[0031] To ensure precise alignment between the split module 21 and the mold core 2 during the injection molding process, a positioning function is provided between the linkage 6 and the mold core 2, as detailed below: like Figure 4 , Figure 5 As shown, the linkage 6 includes a strip 61. A sliding cavity 23 is provided at the rear of the mold core 2. The rear end of the split module 21 can be slidably inserted into the sliding cavity 23. The strip 61 is adapted to slide into the sliding cavity 23. The split module 21 is connected to the strip 61. Two corner plates 65 are symmetrically rotated and installed in the strip 61. The front of the corner plate 65 has a positioning block 64. The inner wall of the sliding cavity 23 has a positioning groove 24. The two corner plates 65 are supported and expanded by a spring, so that the positioning block 64 is inserted into the positioning groove 24. A shaft 62 is slidably inserted in the strip 61. One end of the shaft 62 is fixed with an expansion block 63, and the other end is connected to the hydraulic cylinder 3. The expansion block 63 is located between the two corner plates 65.
[0032] The linkage 6 is positioned and fixed in the slide cavity 23 by the positioning block 64 engaging with the positioning groove 24, ensuring that the split module 21 and the mold core 2 are precisely matched to form the injection molding surface. During the demolding process, the hydraulic cylinder 3 retracts, driving the shaft column 62 and the expansion block 63 to retract. The expansion block 63 presses against the rear of the corner plate 65 to expand, causing the positioning block 64 at the front end of the corner plate 65 to move closer to and separate from the positioning groove 24, thus releasing the positioning of the linkage 6. The hydraulic cylinder 3 continues to drive the shaft column 62 to retract, and the expansion block 63 abuts against the strip 61 to retract, causing the split module 21 to retract and separate from the middle part of the guide plate.
[0033] The end of the positioning block 64 is spherical, which allows the positioning block 64 to be adapted to the positioning slot 24 for positioning.
[0034] To further disperse the stress intensity during demolding, such as Figure 6 As shown, the split module 21 is divided into a fixed module 211 and a moving module 212, so that the fixed module 211 and the moving module 212 are separated into different stages of the guide plate, as detailed below: The fixed module 211 is fixedly connected to the strip 61. The rear end of the moving module 212 is fixed with a widened card seat 67. The surface of the strip 61 is provided with a card groove 66. The card seat 67 is adapted to be inserted into the card groove 66. The card seat 67 has guide blocks 68 on both sides. The card groove 66 has guide slots 69 on both sides. The guide blocks 68 and the guide slots 69 are slidably connected. A compression spring is connected between the card seat 67 and the card groove 66.
[0035] During the injection molding process, the strip 61 pushes the retainer 67, and the front part of the retainer 67 abuts against the inner end face of the slide cavity 23, keeping the moving module 212 in a fixed position. During the demolding process, the hydraulic cylinder 3 drives the strip 61 to retreat, and the strip 61 drives the fixed module 211 to retreat synchronously. At this time, under the action of elastic force, in conjunction with the sliding of the guide block 68 and the guide groove 69, the moving module 212 keeps its position fixed. When the strip 61 retreats to the end of the guide block 68 abutting the guide groove 69, the moving module 212 follows the strip 61 to retreat, thereby achieving the effect of the fixed module 211 and the moving module 212 retreating separately and separating from the guide plate.
[0036] The staggered distribution of the fixed module 211 and the moving module 212 makes the stress distribution more uniform during the staged retraction of the fixed module 211 and the moving module 212, ensuring that the guide plate separates stably and orderly from the fixed module 211 and the moving module 212.
[0037] There is a gap between the end of the rocker 4 and the strip 61. The strip 61 keeps moving the moving module 212 back before pressing against the rocker 4 to twist. Thus, in the whole demolding process, the stationary module 211 first separates from the guide plate, then the moving module 212 separates from the guide plate, and finally the ejector module 22 pushes the guide plate off, so that the whole demolding process is divided into three stages.
[0038] like Figure 6 As shown, a pressure sensor 7 is provided on the front surface of the strip 61. The pressure sensor 7 is connected to the host of the injection mold through the controller. During the injection process, the linkage 6 is positioned in the slide cavity 23. The pressure sensor 7 abuts against the inner end face of the slide cavity 23 to provide feedback on position information, so that the operator can obtain the distribution status of the split module 21 in a timely manner.
[0039] Although embodiments of the invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the invention.
