Description

Technical Field

[0001] This utility model relates to the technical field of demolding mechanisms, specifically a multi-block synchronous demolding mechanism for preventing damage to electric vehicle foot pedals. Background Technology

[0002] With increasing environmental awareness and technological advancements, electric vehicles, as a clean and efficient mode of transportation, have gained widespread popularity and application in recent years. Electric vehicle footrests, as a crucial component, not only support passenger weight and provide a stable standing platform, but also often integrate complex structures such as battery compartment covers and folding mechanisms to meet the diverse needs of users. In the manufacturing process of electric vehicle footrests, molds play a vital role. Mold design directly affects the product's shape, size, precision, and production efficiency. Electric vehicle footrest molds typically employ injection molding, where molten material is injected into the mold through its internal cavities and runners, and after cooling and solidification, it forms the desired footrest shape.

[0003] The complex structure of electric vehicle pedals, including multiple protrusions and recesses, as well as intricate textures and patterns, significantly increases the difficulty of mold design and production. Particularly during the demolding process, ensuring the pedal smoothly exits the mold while avoiding damage to both the pedal and the mold has become a pressing technical challenge.

[0004] Traditional mold designs typically employ a single ejection mechanism, such as an ejector pin or ejector block, to push the foot pedal out of the mold. However, due to the complex structure of electric vehicle foot pedals, a single ejection mechanism struggles to achieve uniform demolding force, easily leading to foot pedal deformation or damage. Furthermore, during demolding, excessive or uneven ejection force can easily damage the mold cavity and runner, affecting mold lifespan and product quality. Utility Model Content

[0005] The purpose of this utility model is to provide a multi-ejector synchronous demolding mechanism for electric vehicle pedals to prevent damage, in order to solve the problems mentioned in the background art, which are that due to the complex structure of electric vehicle pedals, a single ejection mechanism is difficult to achieve uniform demolding force, which can easily lead to pedal deformation or damage. If the ejection force is too large or unevenly distributed, it can easily damage the mold cavity and runner.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a multi-top block synchronous demolding mechanism for preventing damage to electric vehicle foot pedals, which is configured in conjunction with a lower mold. Upper limit guide posts are fixed at the four corners of the upper end of the lower mold. A mold cavity is opened in the middle of the upper end face of the lower mold. Several top block grooves are opened in the lower end face of the mold cavity. A top rod sliding groove is opened along the lower end of the top block groove inside the lower mold. The demolding mechanism includes a support base plate.

[0007] The upper left and right sides and the middle of the support base plate are all welded and fixed with fixed upright plates, and a transverse limiting rod is fixed between two adjacent fixed upright plates.

[0008] The support base plate is provided with left and right moving components on the upper left and right sides. The left and right moving components include a sliding block body. The sliding block body is located outside the horizontal limiting rod and slides along the horizontal limiting rod. The outer sides of the front and rear ends of the sliding block body are integrally connected with an outer expansion plate. Multiple linkage arms are arrayed on the upper end of the outer expansion plate. The other end of the multiple linkage arms is provided with an ejection unit. The ejection unit includes an upper top plate. The other end of the linkage arm is fixed to the upper top plate.

[0009] The linkage arm consists of two fixed seats and a middle linkage rotating rod. The two ends of the middle linkage rotating rod extend into the two fixed seats respectively and are rotatably connected to the fixed seats through a shaft.

[0010] An ejection assembly is provided at the upper end of the top plate at a position corresponding vertically to the top rod sliding groove and the top block groove. The ejection assembly includes an upper top block and an upper top rod. The upper top block is fixed to the upper end of the upper top rod. The upper top block matches the size and shape of the top block groove. The upper top block slides along the top block groove. The upper top rod matches the diameter of the top rod sliding groove. The upper top rod slides along the top rod sliding groove.

[0011] Preferably, the sliding block body has a through groove running vertically through its middle.

[0012] Preferably, the lower mold is provided with two pressing components. The pressing components include a pressing rod and an upper fixed plate. The pressing rod is fixed in the middle to the lower end of the upper fixed plate. A pressing block is fixed to the lower end of the pressing rod. The pressing block passes through the through groove on the sliding block body and is fixed with a limiting base plate. The pressing block has through holes on the left and right sides. A lateral limiting rod passes through the through holes on the pressing block.

[0013] Preferably, the outer surface of the pressing block is a first inclined surface, and the outer surface of the through groove is a second inclined surface. The first inclined surface and the second inclined surface have the same inclination, and the pressing block and the sliding block body are in contact through the first inclined surface and the second inclined surface.

[0014] Preferably, a limiting member is fixed at the upper end of the top plate at a position corresponding to the vertical position of the ejection component, and a T-shaped groove is formed through the upper end face of the limiting member on the left and right.

[0015] Preferably, a lower extrusion member is fixed to the lower end of the upper push rod, and a lower action extrusion groove is formed inside the lower mold along the lower end of the push rod sliding groove. The sum of the widths of the two vertical parts of the lower extrusion member is less than the width of the lower action extrusion groove. The lateral dimension of the lower extrusion member matches the lateral cross-sectional dimension of the lower action extrusion groove. Lower support feet are fixed to the lower outer ends of the two vertical parts of the lower extrusion member. A lower limit part is integrally connected to the front and rear ends of the lower end of the lower support foot. The lower limit part and the lower support foot match the T-shaped groove and slide along the T-shaped groove.

[0016] Preferably, the upper end face of the lower mold has recessed slots on both sides, the upper fixing plate matches the diameter of the recessed slots, the lower mold has a lower limit guide groove along the lower end of the recessed slots, the lower limit guide groove extends downward, the lower pressure rod slides in the lower limit guide groove, and a second pressure spring is provided between the upper fixing plate and the lower mold along the outside of the lower pressure rod.

[0017] Preferably, a first pressure spring is provided on the outside of the transverse limiting rod between the fixed plate and the sliding block body.

[0018] Compared with the prior art, the beneficial effects of this utility model are:

[0019] (1) In this utility model, multiple top blocks are provided. In order to ensure the movement of multiple top blocks, linkage arms are provided, and multiple sets of linkage arms are evenly arranged under the ejection structure. Through the linkage of the left and right moving components and the linkage arms, the synchronous demolding of multiple top blocks is achieved, ensuring the uniformity and stability of demolding, and effectively avoiding the problem of foot pedal deformation or damage.

[0020] (2) In this utility model, due to the use of a multi-top block synchronous demolding method, the impact force can be dispersed during the demolding process, which effectively reduces the damage to the mold and extends the service life of the mold.

[0021] (3) In this utility model, when the injection molding machine drives the upper mold to move downward along the upper limit guide post, the upper mold will press the upper fixed plate, causing the lower pressing component to move downward as a whole. Because the first inclined surface of the lower pressing block is in contact with the second inclined surface of the sliding block body, and there are first pressure springs on both sides of the sliding block body, when the lower pressing component moves downward, it will drive the two left and right moving components to slide outward synchronously. Due to the existence of the linkage arm, the rotating rod of the linkage arm will rotate and pull the upper top plate downward. This makes the top block shrinkage of this demolding device not require a separate driving structure, but directly utilizes the existing structure's movement process in conjunction with the linkage structure, so that no manual or control of the structure's action is required before injection molding, and injection molding can be performed directly. After molding, the elastic action of multiple springs is used to reset the structure, thereby ejecting the finished product, realizing automated demolding, reducing manual intervention, and improving production efficiency.

[0022] (4) In this utility model, the two vertical parts of the lower extruder move downwards. After losing the pressure from the lower action extrusion groove, the two vertical parts of the lower extruder, as well as the lower support foot and the lower limit part, gradually move outwards, further pulling the upper ejector block into the ejector block groove. The ejector unit moves upwards, and the lower action extrusion groove squeezes the two vertical parts of the lower extruder, causing the two vertical parts of the lower extruder to squeeze inwards, driving the upper ejector block to move further upwards. With a fixed stroke height, the cooperation between the lower extruder and the lower action extrusion groove expands the ejection stroke of the ejector block, ensuring that the ejector block can accurately and stably push the foot pedal out of the mold.

[0034] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0035] Please see Figure 1-10 One embodiment provided by this utility model:

[0036] Lower mold and supporting structure: Upper limit guide posts 4 are fixed at the four corners of the upper end of the lower mold 1 for positioning in conjunction with the upper mold. A mold cavity 5 is formed in the middle of the upper end face of the lower mold 1 for injection molding of electric vehicle foot pedals. Several ejector block grooves 6 are formed on the lower end face inside the mold cavity 5 for accommodating ejector blocks. An ejector rod sliding groove 7 is formed inside the lower mold 1 along the lower end of the ejector block groove 6 for ejector rod sliding. A lower action extrusion groove 8 is formed inside the lower mold 1 along the lower end of the ejector rod sliding groove 7 for extrusion and ejection of the subsequent ejection structure.

[0037] Left and right moving components 16 are provided on both the left and right sides of the upper end of the support base plate 24; fixed upright plates 21 are welded and fixed to the left, right and middle sides of the upper end of the support base plate 24, and a transverse limiting rod 22 is fixed between two adjacent fixed upright plates 21 to limit the sliding range of the left and right moving components 16. The support structure is stable, ensuring the stability and reliability of the demolding mechanism.

[0038] Left-right movement structure and linkage structure: The left-right movement component 16 includes a sliding block body 17, which is located outside the transverse limiting rod 22 and slides along the transverse limiting rod 22. A through groove 18 is formed vertically through the middle of the sliding block body 17. An outer extension plate 20 is integrally connected to the outer sides of both the front and rear ends of the sliding block body 17. Multiple linkage arms 25 are arrayed on the upper end of the outer extension plate 20. Each linkage arm 25 consists of two fixed seats and a central linkage rotating rod. Both ends of the central linkage rotating rod extend into the two fixed seats and are rotatably connected to the fixed seats via shafts. The other ends of the multiple linkage arms 25 are collectively provided with an ejection unit 26, which includes an upper top plate 27. The other ends of the linkage arms 25 are fixed to the upper top plate 27.

[0039] The linkage between the left and right moving component 16 and the linkage arm 25 enables the synchronous demolding of multiple top blocks, ensuring the uniformity and stability of demolding.

[0040] A first pressure spring 23 is provided on the outside of the horizontal limiting rod 22 between the fixed plate 21 and the sliding block body 17. The first pressure spring 23 ensures that the left and right moving component 16 can automatically reset after losing the squeezing force, in preparation for the next demolding.

[0041] Ejection and limiting structure: An ejection assembly 30 is provided at the upper end of the upper top plate 27, corresponding vertically to the ejector sliding groove 7 and the ejector block groove 6. The ejection assembly 30 includes an upper ejector block 31 and an upper ejector rod 32. The upper ejector block 31 is fixed to the upper end of the upper ejector rod 32. The upper ejector block 31 matches the size and shape of the ejector block groove 6, and the upper ejector block 31 slides along the ejector block groove 6. The upper ejector rod 32 matches the diameter of the ejector sliding groove 7, and the upper ejector rod 32 slides along the ejector sliding groove 7.

[0042] A limiting member 28 is fixed at the upper end of the top plate 27, corresponding vertically to the ejector assembly 30. A T-shaped groove 29 is formed through the upper surface of the limiting member 28 on both sides. A lower extrusion member 33 is fixed to the lower end of the top rod 32. The lower extrusion member 33 is made of elastic metal and can deform slightly under pressure and return to its original position when the pressure is released. The sum of the widths of the two vertical parts of the lower extrusion member 33 is less than the width of the lower action extrusion groove 8, and the lateral dimensions of the lower extrusion member 33 match the lateral cross-sectional dimensions of the lower action extrusion groove 8. Lower support legs 34 are fixed to the lower outer lower ends of the two vertical parts of the lower extrusion member 33. A lower limiting part 35 is integrally connected to the front and rear ends of the lower support legs 34. The lower limiting part 35 and the lower support legs 34 match the T-shaped groove 29 and slide along the T-shaped groove 29. The two vertical sections of the lower extrusion member 33 move downwards. After losing the pressure from the lower extrusion groove 8, the two vertical sections of the lower extrusion member 33, as well as the lower support leg 34 and the lower limit part 35, gradually move outwards, further pulling the upper ejector block 31 into the ejector block groove 6. The ejection unit 26 moves upwards, and the lower extrusion groove 8 presses against the two vertical sections of the lower extrusion member 33, causing the two vertical sections of the lower extrusion member 33 to press inwards, driving the upper ejector block 31 to move further upwards. The ejection structure and the limit structure ensure that the ejector block can accurately and stably push the foot pedal out of the mold.

[0043] The pressing structure and inclined surface design: Two pressing components 9 are provided on the lower mold 1. The pressing component 9 includes a pressing rod 10 and an upper fixed plate 11. The pressing rod 10 is fixed in the center to the lower end of the upper fixed plate 11, and a pressing block 12 is fixed to the lower end of the pressing rod 10. The pressing block 12 passes through the through groove 18 on the sliding block body 17 and is fixed with a limiting base plate 13. The pressing block 12 has through holes 15 on the left and right sides, and the lateral limiting rod 22 passes through the through holes 15 on the pressing block 12. The outer side of the pressing block 12 is a first inclined surface 14, and the outer side of the through groove 18 is a second inclined surface 19. The first inclined surface 14 and the second inclined surface 19 have the same inclination. The pressing block 12 and the sliding block body 17 are in contact through the first inclined surface 14 and the second inclined surface 19.

[0044] The downward pressing structure and inclined surface design enable the synchronous outward sliding of the left and right moving components 16, providing power for the synchronous demolding of the top block.

[0045] The lower extrusion structure and reset structure: The upper end face of the lower die 1 has two recessed slots 3 on both sides, and the upper fixed plate 11 matches the diameter of the recessed slots 3. A lower limit guide groove 2 is provided along the lower end of the recessed slots 3 on the upper part of the lower die 1, extending downwards, and the lower pressure rod 10 slides within the lower limit guide groove 2. A second pressure spring 36 is provided between the upper fixed plate 11 and the lower die 1 along the outside of the lower pressure rod 10.

[0046] The design of the lower extrusion part and the reset structure enables the top block to be reset and ejected again, ensuring the continuity and stability of demolding.

[0047] Working principle: When the injection molding machine drives the upper mold to move downward along the upper limit guide post 4, the upper mold will press against the upper fixed plate 11, causing the lower pressing assembly 9 to move downward as a whole. Because the first inclined surface 14 of the lower pressing block 12 is in contact with the second inclined surface 19 of the sliding block body 17, and there are first pressure springs 23 on both sides of the sliding block body 17, when the lower pressing assembly 9 moves downward, it will drive the two left and right moving assemblies 16 to slide outward synchronously. Due to the presence of the linkage arm 25, the rotating rod of the linkage arm 25 will rotate and pull the upper top plate 27 downward.

[0048] The two vertical parts of the lower extrusion member 33 move downwards. After the lower extrusion groove 8 stops pressing on them, the two vertical parts of the lower extrusion member 33, as well as the lower support leg 34 and the lower limit part 35, will gradually move outwards, further pulling the upper top block 31 into the top block groove 6.

[0049] After injection molding and cooling, the electric vehicle pedal is formed. The injection molding machine drives the upper mold to move upward along the upper limit guide post 4. Due to the presence of the first pressure spring 23 and the second pressure spring 36, the lower pressing component 9 and the left and right moving component 16 are reset. Through the linkage of the linkage arm 25, the ejector unit 26 moves upward, pushing the formed electric vehicle pedal upward. At the same time, the lower extrusion groove 8 will squeeze the two vertical parts of the lower extrusion part 33, causing the two vertical parts of the lower extrusion part 33 to squeeze inward, driving the upper ejector block 31 to move further upward. The upper ejector block 31 pushes the formed electric vehicle pedal upward to make it leave the mold cavity 5.

[0050] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention. No reference numerals in the claims should be construed as limiting the scope of the claims.
