Description

Technical Field

[0001] The invention relates to the technical field of molds, and in particular to a lampshade molding device and a molding method thereof. Background Art

[0002] The headlights of a car refer to the lamps on the vehicle, which are the tools for lighting the road when the vehicle is driving at night. In the design concept of modern vehicles, in addition to functionality, aesthetics is also one of the important factors in vehicle design. As an important part of the vehicle surface, the headlights also need to be aesthetically pleasing. Therefore, when designing modern headlights, different models of cars will design headlights of different shapes to reflect the design language of the car. The headlights include lampshades and bulbs in the lampshades. The shape of the headlights is usually determined by the lampshades, and the shapes of the lampshades vary. Therefore, when producing lampshades, mold forming processes are usually used. The mold controls and restricts the flow of materials to form the required shape. The mold forming process is widely used in the production of lampshades due to its high efficiency, good product quality, low material consumption and low production cost.

[0003] The injection mold of an automobile lampshade with the publication number CN116175909A comprises a mold frame, a slider and a driving connecting rod capable of driving the slider to move up and down, the slider is provided with a plug rod and a control rod which are horizontally placed on the left and right and coaxially movably connected, an elastic member which can be compressed when the plug rod and the control rod slide towards each other is arranged against each other, the inner side wall of the mold frame has a positioning hole, the end of the plug rod extending out of the slider is positioned and inserted in the positioning hole, the upper end of the driving connecting rod is movably connected with the end of the control rod and is always limited in the left and right directions, the driving connecting rod can move downward relative to the slider so that the control rod drives the plug rod to move toward the side where the driving connecting rod is located and disengage from the positioning hole. The above invention can avoid the direct fall of the slider causing product damage and ensure product quality.

[0004] Although the above patent can prevent the slider from falling directly and causing product damage, thereby ensuring product quality, it cannot effectively perform injection molding and demolding of the slots and buckles on the front side of the lampshade.

[0013] Preferably, a connecting plate is fixedly provided at one end of the driving plate located inside the installation box, and the connecting plate is fixedly connected to the slide by bolts. When the connecting plate slides in the installation box, it can drive the driving plate and the slide to move synchronously.

[0014] Preferably, the driving part includes: a mounting plate which is fixedly arranged on one side of the lower die base through bolts and can fixedly install the mounting box inside the lower die base; a telescopic member, whose fixed end is fixedly arranged on one side of the mounting plate, and whose movable end penetrates through and extends into the mounting box and is fixedly connected with the connecting plate.

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0030] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0031] Embodiment 1, the present invention provides as Figures 1 to 9The forming device for the lampshade shown includes an upper die base 1 and a lower die base 2. Both the upper die base 1 and the lower die base 2 are fixedly installed at the driving end of an injection molding machine. The injection molding machine can drive the upper die base 1 and the lower die base 2 to close / open the mold and inject plastic into the upper die base 1 and the lower die base 2 after closing the mold. The injection molding machine is a prior art and will not be elaborated here. It is not shown in the figure. A forming cavity is provided at the bottom of the upper die base 1, and a forming concave cavity is provided at the top of the lower die base 2. A forming die base is fixedly provided in the forming concave cavity. When the upper die base 1 and the lower die base 2 are closed, the forming cavity and the forming die base cooperate with each other to inject and mold the lampshade 3. The forming cavity, the forming concave cavity and the forming die base are all prior arts and will not be elaborated here. The upper die base 1 and the lower die base 2 cooperate to integrally inject and mold the lampshade 3. It further includes: A lateral forming assembly 4, which includes a convex die 41 and a concave die 42. The convex die 41 and the concave die 42 cooperate to inject and mold the card slot 31 and the buckle 32 on the front side of the lampshade 3. When injecting and molding the lampshade 3, the convex die 41 and the concave die 42 are in the closed state. When the lampshade 3 is demolded after injection molding, the convex die 41 and the concave die 42 are in the open state.

[0032] Specifically, the convex die 41 is fixedly arranged at one end of the driving plate 51 located in the forming concave cavity of the lower die base 2, and the concave die 42 is fixedly arranged at one end of the driving rod 52 close to the forming concave cavity of the lower die base 2; the convex die 41 and the concave die 42 respectively match the shapes of the card slot 31 and the buckle 32 of the lampshade 3, and both between the convex die 41 and the driving plate 51 and between the concave die 42 and the driving rod 52 can be fixed by bolts.

[0033] It should be noted that when the convex die 41 and the concave die 42 are in the open state, the convex die 41 is hidden inside the forming die base, and the concave die 42 is hidden inside the lower die base 2, so that the convex die 41 and the concave die 42 will not interfere with the injection molding and demolding of the lampshade 3 and ensure the smooth progress of the injection molding process.

[0034] A lateral mold withdrawal mechanism 5. When the lateral mold withdrawal mechanism 5 controls the convex die 41 and the concave die 42 to close, it can inject and mold the card slot 31 and the buckle 32. When the lateral mold withdrawal mechanism 5 controls the convex die 41 and the concave die 42 to open, it can separate the convex die 41 and the concave die 42 from the formed card slot 31 and buckle 32 respectively, so as to facilitate the demolding of the lampshade 3.

[0035] When the convex die 41 and the concave die 42 are closed, the structural shapes of the card slot 31 and the buckle 32 are formed between them, so that the card slot 31 and the buckle 32 are integrally formed during the injection molding process. When the convex die 41 and the concave die 42 are open, the convex die 41 is separated from the card slot 31, and the concave die 42 is separated from the buckle 32, so as to facilitate the demolding of the lampshade 3.

[0036] Specifically, the lateral mold withdrawal mechanism 5 includes a driving plate 51 and a driving rod 52 that are slidably arranged inside the lower mold base 2. When the driving plate 51 and the driving rod 52 approach each other, they can drive the male mold 41 and the female mold 42 to close the mold. When the driving plate 51 and the driving rod 52 move away from each other, they can drive the male mold 41 and the female mold 42 to open the mold.

[0037] More specifically, the lateral mold withdrawal mechanism 5 further includes a mounting box 53 that is detachably installed inside the lower mold base 2. One end of the driving plate 51 away from the male mold 41 penetrates and is slidably arranged inside the mounting box 53. A carriage 54 is arranged inside the mounting box 53 and is located above the driving plate 51. The carriage 54 can slide left and right inside the mounting box 53. A fixed seat 55 is fixedly arranged inside the mounting box 53, and the driving rod 52 penetrates and is slidably arranged inside the fixed seat 55. The driving rod 52 can slide left and right inside the fixed seat 55. A chute 56 is penetrated and opened on the fixed seat 55, and the driving rod 52 penetrates through the middle of the chute 56. A Z-shaped frame 57 is slidably arranged up and down inside the chute 56.

[0038] At the same time, two driving inclined blocks 58 are arranged oppositely at the upper and lower ends on one side of the carriage 54. Two driven inclined blocks 59 are arranged oppositely at the upper and lower ends of the Z-shaped frame 57. The two driven inclined blocks 59 are respectively matched with the corresponding driving inclined blocks 58. When the carriage 54 drives the driving inclined blocks 58 to slide left and right, it can drive the driven inclined blocks 59 to drive the Z-shaped frame 57 to slide up and down along the chute 56.

[0039] Moreover, the lateral mold withdrawal mechanism 5 further includes an inclined guide groove 510 that obliquely penetrates the driving rod 52. The inclined part of the Z-shaped frame 57 is slidably arranged inside the inclined guide groove 510. When the Z-shaped frame 57 slides up and down inside the chute 56, it can drive the driving rod 52 to slide left and right inside the fixed seat 55.

[0040] Furthermore, one end of the driving plate 51 located inside the mounting box 53 is fixedly provided with an adapter plate 511, and the adapter plate 511 is fixedly connected to the carriage 54 by bolts. When the adapter plate 511 slides inside the mounting box 53, it can drive the driving plate 51 and the carriage 54 to move synchronously.

[0041] A driving part 6 is used to drive the lateral mold withdrawal mechanism 5 to adjust the open / closed state of the lateral molding assembly 4.

[0042] Specifically, the driving part 6 includes a mounting plate 61 that is fixedly arranged on one side of the lower mold base 2 by bolts and can fixedly install the mounting box 53 inside the lower mold base 2. A telescopic member 62 has its fixed end fixedly arranged on one side of the mounting plate 61, and its movable end penetrates and extends into the mounting box 53 and is fixedly connected to the adapter plate 511.

[0043] In summary, when the lamp cover 3 needs to be injection-molded, first control the upper mold base 1 and the lower mold base 2 to perform longitudinal mold closing. Then, control the telescopic member 62 to contract, so that the connecting plate 511 drives the driving plate 51 and the carriage 54 to slide to the right in the installation box 53. During this process, the driving inclined block 58 will drive the driven inclined block 59 to drive the Z-shaped frame 57 to move upward along the chute 56. At this time, through the cooperation between the inclined part of the Z-shaped frame 57 and the inclined guide groove 510, the driving rod 52 will be driven to slide to the left, so that the convex mold 41 and the concave mold 42 approach each other, and the convex mold 41 and the concave mold 42 complete mold closing, as Figure 8 shown in the state, and at this time, injection molding of the lamp cover 3, the card slot 31 and the buckle 32 is carried out.

[0044] After the injection molding is completed, the lamp cover 3 needs to be demolded. At this time, first control the telescopic member 62 to extend, so that the driving plate 51 and the carriage 54 slide to the left. The driving inclined block 58 drives the driven inclined block 59 to drive the Z-shaped frame 57 to move downward. Through the cooperation between the inclined part of the Z-shaped frame 57 and the inclined guide groove 510, the driving rod 52 is driven to slide to the right, and the convex mold 41 and the concave mold 42 move away from each other, so that the convex mold 41 is separated from the card slot 31, and the concave mold 42 is separated from the buckle 32, realizing lateral demolding of the lamp cover 3, as Figure 9 shown in the state, and then control the upper mold base 1 and the lower mold base 2 to open the mold, realizing overall demolding of the lamp cover 3.

[0045] By setting the convex mold 41 and the concave mold 42, while the lamp cover 3 is injection-molded, the card slot 31 and the buckle 32 on the front side of the lamp cover 3 can be integrally injection-molded synchronously, simplifying the injection process of the lamp cover 3 and improving the overall injection molding effect of the lamp cover 3. Moreover, the convex mold 41, the concave mold 42 with split lateral mold opening / closing and the overall detachable lateral core-pulling mechanism 5 not only facilitate the injection molding of the card slot 31 and the buckle 32, but also optimize the structure of the injection mold, making it easy to repair or replace the convex mold 41 and the concave mold 42. When the convex mold 41 or the concave mold 42 is worn after long-term use, it can be directly disassembled and replaced, thereby prolonging the overall service life of the equipment, shortening the time required for equipment maintenance, and improving the injection efficiency.

[0046] During the injection molding process, the telescopic member 62 drives the lateral core-pulling mechanism 5, and the lateral core-pulling mechanism 5 drives the convex mold 41 and the concave mold 42 to approach each other synchronously. Until the convex mold 41 and the concave mold 42 are adjusted to the mold-closed state, the telescopic member 62 stops moving, so that the convex mold 41 and the concave mold 42 are stably maintained in the mold-closed state. The mold-closed state is stable and reliable, and there will be no relative displacement between the convex mold 41 and the concave mold 42 due to the pressure during the injection molding process, thereby ensuring the smooth progress of the injection molding process, and at the same time ensuring the injection molding effect of the card slot 31 and the buckle 32, and improving the injection molding accuracy of the card slot 31 and the buckle 32.

[0047] When demolding the lamp cover 3, the telescopic member 62 drives the lateral mold-pulling mechanism 5 to drive the male mold 41 and the female mold 42 to move away from each other synchronously, so that the male mold 41 and the female mold 42 can be separated from the card slots 31 and the buckles 32 synchronously, improving the force balance of the card slots 31 and the buckles 32 during the demolding process, avoiding deformation or distortion of the front side of the lamp cover 3 caused by uneven demolding force of the card slots 31 and the buckles 32 during the demolding process, and at the same time making room for the longitudinal demolding of the lamp cover 3 to avoid interference with the longitudinal demolding of the lamp cover 3.

[0048] Embodiment 2, the present invention also provides a method for forming a lamp cover, including the following steps: Step 1, longitudinal mold closing, controlling the upper mold base 1 and the lower mold base 2 to approach each other to complete the mold closing between the upper mold base 1 and the lower mold base 2; Step 2, lateral mold closing, controlling the male mold 41 and the female mold 42 to approach each other through the lateral mold-pulling mechanism 5 to complete the mold closing of the lateral forming assembly 4; Step 3, injection molding, injecting the injection molding raw material between the upper mold base 1 and the lower mold base 2 to complete the injection molding of the lamp cover 3; Step 4, lateral mold opening, controlling the male mold 41 and the female mold 42 to move away from each other through the lateral mold-pulling mechanism 5 to complete the demolding between the lateral forming assembly 4 and the card slots 31 and the buckles 32; Step 5, longitudinal mold opening, controlling the upper mold base 1 and the lower mold base 2 to move away from each other to complete the demolding of the lamp cover 3.

[0049] Finally, it should be noted that the above are only the preferred embodiments of the present invention and are not used to limit the present invention. Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments, or perform equivalent replacements for some of the technical features. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included within the protection scope of the present invention.
