A high temperature resistant automobile parts forming die

Abstract

The invention discloses a high-temperature resistant automobile parts forming mold, which relates to the field of mold technology. As the mold is in continuous injection molding work, the material will fill the gap in the mold cavity. If the molded material is directly extracted, demolding is difficult at this time, and the material in the gap is torn and separated from the material, so that a large amount of material exists in the gap, which affects the use of the mold. Through the elastic deformation of the spring plate, when the molding plate is clamped and slid inward, the spring plate is pulled to deform, and a pulling force is generated to pull the molding plate outward through the deformation. After the material is cooled and molded, the molding plate loses the limiting force of the inward clamping. At this time, the spring plate pulls the molding plates apart through the slider, so that the mold is better demolded, and it is avoided that the molded material is directly extracted, so that the material in the gap is torn and separated from the material, so that a large amount of material exists in the gap, which affects the use of the mold.

After the injection molding is completed, the cooling water pipe is connected to the cooling pipe 6, so that the cooling water is injected from one cooling pipe 6 after the injection molding is completed, and the other cooling pipe 6 is discharged, so that the material injected into the mold cavity mechanism 3 is cooled and formed;

[0034] The mold cavity mechanism 3 includes a cavity tube 31 and a top plate 32. The top of the top plate 32 is fixedly connected to the inner wall of the top block 2 by rivets, and the bottom of the cavity tube 31 is fixedly connected to the inner wall of the bottom block 1. A bottom plate 33 is fixedly installed at the bottom of the inner wall of the cavity tube 31. A molding plate 34 is slidably installed on the top of the bottom plate 33. The molding plates 34 are evenly arranged along the center of the bottom plate 33. A sliding assembly 35 is installed on the outer side of the molding plate 34, and the molding plate 34 is connected to the cavity tube 31 through the sliding assembly 35. The top plate 32 and the cavity tube 31 in the mold cavity mechanism 3 are close to each other. The pressure sealing block 38 at the bottom of the top plate 32 clamps the molding plate 34 inward during the close process. The sliding assembly 35 cooperates with the molding plate 34 to slide, so that the molding plates 34 fit closely together to form a cavity. The exhaust assembly 36 and the demoulding assembly 37 cooperate with each other to form a molded cavity. The hot melt material is injected into the formed cavity through the injection pipe 8. The bottom of the top plate 32 is evenly equipped with pressure sealing blocks 38 along the center of the top plate 32.

[0035] The sliding assembly 35 is composed of a spring plate 351, a fixed slot block 352 and a slider 353. The spring plate 351 is symmetrically installed at the top and bottom of the fixed slot block 352, and the end of the spring plate 351 away from the fixed slot block 352 is fixedly connected to the outer side of the slider 353.

After the injection molding cooling is completed, the bottom block 1 is separated from the top block 2. At this time, the pressure sealing block 38 gradually releases the molding plate 34, restores the deformation through the spring plate 351, and pulls the molding plate 34 apart through the slider 353. The exhaust assembly 36 is fixedly installed at the center position of the bottom of the top plate 32, and the demolding assembly 37 is installed at the center position of the bottom of the exhaust assembly 36.

[0036] The second embodiment is based on the first embodiment. Figures 8 to 11 As shown, the exhaust assembly 36 includes an exhaust hood 361, and the exhaust hood 361 is composed of an air hood and a hole plate. The top of the exhaust hood 361 is fixedly connected to the bottom of the top plate 32, and the outer side of the exhaust hood 361 is evenly provided with air outlet holes. The top of the hole plate of the exhaust hood 361 is evenly provided with air outlet holes along the center of the hole plate. During the process of injecting the material, the material is injected into the cavity from the bottom through the injection pipe 8, so that the air inside the cavity is squeezed upward during the continuous injection of the material, and is discharged through the gap between the exhaust hole of the exhaust hood 361 and the sealing block 364, and then guided out through the air outlet hole. The exhaust hole of the exhaust hood 361 is from top to bottom. The aperture gradually increases, and an annular groove is provided at the bottom of the hole plate of the exhaust hood 361, and a sealing block 364 is provided at the exhaust hole of the exhaust hood 361, the sealing block 364 is adapted to the exhaust hole, and a supporting plate 362 is fixedly installed on the top of the sealing block 364, and the bottom of the supporting plate 362 fits with the top of the hole plate. When the material gradually fills the cavity, the viscosity of the material itself pushes the bottom ring 363 to move upward, so that the sealing block 364 gradually blocks the exhaust hole. When it is completely blocked, the bottom ring 363 enters the annular groove of the exhaust hood 361, and a bottom ring 363 is fixedly installed on the bottom of the sealing block 364, and the bottom ring 363 is adapted to the annular groove.

[0037] The demoulding assembly 37 includes a feed tray 371 and a slide column 375. The top of the slide column 375 is fixedly connected to the center position of the bottom of the hole plate of the exhaust hood 361. The bottom of the feed tray 371 is fixedly connected to the inner wall of the bottom block 1. The outer side of the slide column 375 is evenly provided with protrusions. The outer side of the feed tray 371 and the inner wall of the forming plate 34 form a seal during injection. The top of the feed tray 371 is evenly provided with feed holes along the center position of the feed tray 371. The feed holes of the feed tray 371 are fixedly connected to the injection pipe 8. A groove drum 372 is fixedly installed at the center position of the top of the feed tray 371. During the demoulding process, the top block 2 is separated from the bottom block 1. At this time, the slide column 375 is driven to separate by the exhaust hood 361. The sliding column 375 is pulled out from the groove cylinder 372. The outer side of the groove cylinder 372 is evenly provided with sliding grooves. A sliding plate 373 is slidably installed at the sliding groove of the groove cylinder 372. A protrusion is provided on the opposite surface of the sliding plate 373, and the protrusion of the sliding plate 373 is matched with the protrusion of the sliding column 375. Elastic plates 374 are installed at both ends of the opposite surface of the sliding plate 373. The end of the elastic plate 374 away from the sliding plate 373 is fixedly connected to the inner wall of the groove cylinder 372. During the extraction process, the protrusion of the sliding column 375 and the protrusion of the sliding plate 373 are continuously contacted and separated, so that the sliding plate 373 slides outward in this process, pushing the molded parts from the inside to the outside, causing the material to deform and break away from the adhesion with the mold.

[0038] The third embodiment is based on the first and second embodiments. Figure 3 to Figure 4 As shown, the guide mechanism 4 includes a guide rod 41 and a guide cylinder 42. The guide rod 41 is fixedly connected at the fixed groove of the bottom block 1. The top end of the guide rod 41 is a thin rod. The guide cylinder 42 is fixedly installed at the connecting groove of the top block 2. When the top block 2 and the bottom block 1 are driven by the transmission mechanism and approach each other for clamping and sealing, they are guided by the guide mechanism 4. The guide rod 41 and the guide cylinder 42 are respectively connected to the bottom block 1 and the top block 2. In the process of approaching each other, the guide rod 41 penetrates into the inside of the guide cylinder 42. Since the front end of the guide rod 41 is a thin rod, it is easier to enter the inside of the guide cylinder 42 when penetrating. When the top block 2 and the bottom block 1 are constantly approaching, the top end of the guide rod 41 first contacts the arc groove block 46. ​​The top of the inner wall of the guide cylinder 42 is fixedly connected with a limiting cylinder 43. The inner wall of the guide cylinder 42 is evenly provided with guide grooves. An arc groove block 46 is slidably installed at the guide groove of the guide cylinder 42. The bottom of the arc groove block 46 is an arc-shaped surface. A spring 45 and a gasket 44 are installed between the arc groove block 46 and the limiting cylinder 43. There are two gaskets 44. In the process of continuous approach, the front end of the guide rod 41 pushes the arc groove block 46 to slide in the guide cylinder 42, compressing the spring 45 to deform. The deflected guide rod 41 is adjusted in position through the inclined surface at the bottom of the arc groove block 46, so that the thin rod at the top of the guide rod 41 can smoothly penetrate into the limiting cylinder 43, and the spring 45 is fixedly installed between the gaskets 44.

[0039] When in use, the connecting plate 5 and the connecting block 7 are connected to the external transmission mechanism respectively, so that the top block 2 and the bottom block 1 are connected to the transmission mechanism respectively, and the transmission mechanism drives the top block 2 and the bottom block 1 to slide in a directional manner through the guide mechanism 4 to fit tightly to form a seal, and at the same time, the mold cavity mechanism 3 forms an injection molding cavity, and the hot melt material is injected into the mold cavity mechanism 3 through the injection pipe 8. After the injection molding is completed, the cooling water pipe is connected to the cooling pipe 6, so that the cooling water is injected from one cooling pipe 6 after the injection molding is completed, and the other cooling pipe 6 is discharged, so that the material injected into the mold cavity mechanism 3 is cooled and formed.

[0040] When the top block 2 and the bottom block 1 are driven by the transmission mechanism and approach each other for clamping and sealing, they are guided by the guide mechanism 4, and the guide rod 41 and the guide cylinder 42 are respectively connected to the bottom block 1 and the top block 2. In the process of approaching each other, the guide rod 41 penetrates into the interior of the guide cylinder 42. Since the front end of the guide rod 41 is a thin rod, it is easier to enter the interior of the guide cylinder 42 when penetrating. When the top block 2 and the bottom block 1 are constantly approaching, the top end of the guide rod 41 first contacts the arc groove block 46. In the process of constantly approaching, the front end of the guide rod 41 pushes the arc groove block 46 to slide in the guide cylinder 42, compressing the spring 45 to deform, and the deflected guide rod 41 is adjusted in position through the inclined surface at the bottom of the arc groove block 46, so that the thin rod at the top end of the guide rod 41 can smoothly penetrate into the limiting cylinder 43.

[0041] During the process of the top block 2 and the bottom block 1 being fitted together, the top plate 32 and the cavity tube 31 in the mold cavity mechanism 3 approach each other, and the molding plate 34 is clamped inward by the pressure sealing block 38 at the bottom of the top plate 32 during the approaching process, and the sliding assembly 35 cooperates with the molding plate 34 to slide, so that the molding plates 34 are tightly fitted to form a cavity, and the exhaust assembly 36 and the demolding assembly 37 cooperate with each other to form a molded cavity, and the hot melt material is injected into the formed cavity through the injection pipe 8.

[0042] In the sliding assembly 35, the molding plate 34 is subjected to an inward clamping force. When sliding, the spring plate 351 is deformed by the pulling force of the slider 353, so that the slider 353 slides inside the fixed groove block 352. After the injection molding cooling is completed, the bottom block 1 is separated from the top block 2. At this time, the sealing block 38 gradually releases the molding plate 34, restores the deformation through the spring plate 351, and pulls the molding plate 34 apart through the slider 353.

[0043] During the process of injecting the material, the material is injected into the cavity from the bottom through the injection pipe 8, so that the air inside the cavity is squeezed upward during the continuous injection of the material, and is discharged through the gap between the exhaust hole of the exhaust hood 361 and the sealing block 364, and then discharged through the air outlet. When the material gradually fills the cavity, the viscosity of the material itself pushes the bottom ring 363 to move upward, so that the sealing block 364 gradually blocks the exhaust hole. When it is completely blocked, the bottom ring 363 enters the ring groove of the exhaust hood 361.

[0044] During the demoulding process, the top block 2 is separated from the bottom block 1. At this time, the slide column 375 is driven and separated by the exhaust hood 361, so that the slide column 375 is pulled out from the groove barrel 372. During the pulling-out process, the protrusion of the slide column 375 and the protrusion of the sliding plate 373 are constantly in contact and separated, so that the sliding plate 373 slides outward in this process, pushing the molded parts from the inside to the outside, causing the material to deform and break away from the adhesion to the mold.

[0045] Obviously, the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field and related fields without creative work should fall within the scope of protection of the present invention. The structures, devices and operating methods not specifically described and explained in the present invention are implemented according to the conventional means in the field unless otherwise specified and limited.
