Description

Technical Field

[0001] The present invention relates to the technical field of injection molds for automotive parts, and specifically to a mold base for a lightweight new energy vehicle injection mold. Background Art

[0002] Lightweight automotive injection molds and mold bases mainly refer to replacing traditional steel materials with lightweight and high-strength materials such as aluminum alloy, magnesium alloy, or carbon fiber-reinforced plastics, which can effectively reduce the weight of the mold and mold base. When using such molds to inject and produce shock absorber top rubber blocks on new energy vehicles, the moving mold base and the fixed mold base are combined, and then plastic raw materials are injected into the mold cavities of the two mold bases. After the plastic raw materials are cured, the moving mold base and the fixed mold base are separated to achieve product demolding; In order to prevent the product from adhering to the mold cavity and hindering demolding, demolding rods are installed on most mold bases with mold cavities. The demolding rods can be inserted into the mold cavity to eject the product from the mold cavity. However, during the injection process, the end face of the demolding rod sometimes adheres to the product, resulting in flash at the position of the product near the demolding rod during the process of the demolding rod ejecting the product. And the mold cavities of most such molds are not convenient to expose for cleaning residual plastic or dirt, resulting in dirt in the mold cavity affecting the appearance quality of the product, such as black spots, bright spots, roughness and other defects. Summary of the Invention

[0003] The purpose of the present invention is to provide a mold base for a lightweight new energy vehicle injection mold to solve the problems raised in the above background art.

[0004] To achieve the above purpose, the present invention provides the following technical solutions: A mold base for a lightweight new energy vehicle injection mold, comprising: A bottom plate; A fixed mold, the fixed mold includes a rectangular frame fixed to the bottom plate, and a fixed mold base is rotatably arranged inside the rectangular frame; A moving mold, the moving mold includes two columns both fixed to the bottom plate, a first lead screw is rotatably arranged between the column and the rectangular frame, and a moving mold base is screwed and connected between the two first lead screws; A mold base, the mold base includes a slide rail fixed to the bottom plate, an electric slider slides on the slide rail, a first guide rail is fixed to the top of the electric slider, and a second guide rail is screwed and driven on the outside of the first guide rail; A cleaning component, rotatably driven on the outside of the second guide rail, the cleaning component includes a triangular frame, and demolding rods that are rotatably connected to each other are arranged at the three corners of the triangular frame, and a brush is fixed to the outside of the demolding rod; An injection component, arranged inside one demolding rod, for conveying injection raw materials to the mold cavity.

[0005] Furthermore, a fifth motor capable of driving the demolding rod at the corresponding position to rotate is fixed on the outer side of the tripod, and the adjacent two demolding rods are connected by a synchronous belt drive. A blowing air pipe is fixed in the middle of the tripod.

[0006] Furthermore, a second lead screw rotates inside the first guide rail. The second lead screw is in threaded connection with the fourth guide rail, and a third motor capable of driving the second lead screw to rotate is fixed on the top of the first guide rail.

[0007] Furthermore, a third lead screw rotates inside the second guide rail. The third lead screw is in threaded connection with the tripod, and a fourth motor capable of driving the third lead screw to rotate is fixed at one end of the second guide rail.

[0008] Furthermore, a first motor capable of driving the fixed mold base to rotate is fixed on the top of the rectangular frame, and a second motor capable of driving the first lead screw to rotate is fixed on the top of the column.

[0009] Furthermore, a guide shaft fixed to the rectangular frame is fixed on the top of the column, and the guide shaft is slidably connected to the moving mold base.

[0010] Furthermore, an aggregate box is placed between the column and the rectangular frame.

[0011] Furthermore, a round hole is opened at one end of one of the demolding rods, a frustum-shaped hole communicating with the round hole is opened at the other end of the demolding rod, and a convex block is fixed inside the round hole.

[0012] Furthermore, the injection molding assembly includes: An injection cylinder is rotatably inserted into one end of the round hole on the demolding rod, and one end of the injection cylinder is fixed to the tripod; A shaft rod is slidably inserted into the injection cylinder. A frustum-shaped block is fixed at one end of the shaft rod, and the frustum-shaped block is adaptively inserted into the frustum-shaped hole; An electric push rod is fixed on the outer side of the tripod and can drive the shaft rod to move in the round hole.

[0013] Furthermore, a support pipe slidably sleeved with the shaft rod is fixed inside the injection cylinder. A chute for slidably clamping with the convex block is opened on the outer side of the shaft rod, and a connecting block rotatably connected to the shaft rod is fixed at the output end of the electric push rod.

[0014] Compared with the prior art, the beneficial effects of the present invention are: 1. By rotatably connecting multiple demolding rods to the tripod, when injecting plastic after the moving mold and the fixed mold are combined, the mold base drives the multiple demolding rods to be inserted into the demolding holes of the fixed mold base, making the end faces of the demolding rods flush with the inner side of the mold cavity. At the same time, the fifth motor drives the demolding rod at its output end to rotate, and under the driving action of the synchronous belt and the pulley, the multiple demolding rods rotate synchronously, so as to realize the rotation of the demolding rods on the inner side of the mold cavity during the injection molding process, which can effectively prevent the injection molding raw material from solidifying with the end faces of the traditional stationary demolding rods, resulting in flash burrs during demolding. After the injection molding raw material in the mold cavity solidifies into a product, the moving mold base can be driven to leave the fixed mold base, and at the same time, the mold base drives the tripod with multiple demolding rods to move towards the mold cavity, and the demolding rods facilitate the ejection of the top rubber block from the mold cavity.

[0015] 2. By providing multiple mold cavities on both sides of the fixed mold base, and the fixed mold base is rotatably installed on the fixed mold. When the mold cavity on one side of the fixed mold base completes one injection molding process, the first motor can be used to drive the fixed mold base to rotate by 180 degrees, so that the mold cavity that may be dirty after one injection molding process rotates and is exposed outside the brush, and the clean spare mold cavity on the fixed mold base rotates to the injection molding station to be combined with the moving mold base for standby. After the moving mold base and the fixed mold base are combined again, the clean mold cavity can continue to inject and process products with appearance quality meeting the process requirements. At the same time, the rotation of the multiple demolding rods during the injection molding process will drive the brush to rotate in the dirty mold cavity, which is convenient for automatically cleaning the used mold cavity during the injection molding process, enabling the mold to continuously supply clean mold cavities for injection molding, which is beneficial to improving the appearance quality of the top rubber block injection molded products.

DETAILED DESCRIPTION

[0018] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0019] For example 1, please refer to Figure 1 - Figure 8 In an embodiment of the present invention, a lightweight new energy vehicle injection mold mold frame includes a base plate 100, a fixed mold 200 is provided in the middle of the top surface of the base plate 100, the fixed mold 200 includes a rectangular frame 210 fixedly connected to the base plate 100, a fixed mold base 220 is rotatably connected inside the rectangular frame 210, a plurality of top glue block mold cavities are opened on both sides of the fixed mold base 220, a movable mold 300 is arranged on one side of the fixed mold base 220, the movable mold 300 includes two columns 310 both fixedly connected to the base plate 100, a screw rod 320 is rotatably connected between the column 310 and the rectangular frame 210, and a movable mold base 330 is screwed together between the two screw rods 320, and the bottom A mold frame 500 is provided at one end of the top surface of the plate 100, and the mold frame 500 includes a slide rail 510 fixedly connected to the base plate 100, and an electric slider 520 is slidably connected to the slide rail 510, and a guide rail 1 530 is fixed on the top of the electric slider 520, and a guide rail 2 540 is screwed and slidably connected to the outer side of the guide rail 1 530, and a cleaning component 600 is screwed and slidably connected to the outer side of the guide rail 2 540. The cleaning component 600 includes a tripod 610, and demolding rods 620 that are rotated and connected to each other at the three corners of the tripod 610, and a brush 630 is fixed to the outside of the demolding rod 620, wherein an injection molding component 700 for conveying injection molding raw materials to the mold cavity is arranged inside one of the demolding rods 620.

[0020] Specifically, by providing multiple mold cavities for producing top glue blocks on both sides of the fixed mold base 220, the mold cavities on both sides can be rotated and switched to successively engage with the movable mold base 330 to produce the top glue blocks. When the mold cavity on one side of the fixed mold base 220 is engaged with the movable mold base 330 for injection molding to produce the top glue blocks, the mold frame 500 can move to the outside of the mold cavity on the other side of the fixed mold base 220 with multiple demolding rods 620 on the tripod 610. The demolding rods 620 rotate to allow the brushes 630 to clean the dirt inside the exposed mold cavity, so that the clean mold cavity can be recycled for injection molding during the injection molding process. The mold cavity with residual dirt after use can be rotated and exposed during the next injection molding process for automatic cleaning, which is beneficial to ensuring the appearance quality of the product. In the process of the demolding rod 620 driving the brush 630 to rotate to clean the mold cavity, the end face of the demolding rod 620 can rotate on the inner side of the mold cavity, effectively preventing the injection molding material from adhering to the end face of the demolding rod 620 during the injection molding and curing process to cause flash.

[0021] like Figure 6 and Figure 7 As shown, in this embodiment, a motor 640 capable of driving the corresponding position demolding rod 620 to rotate is fixed to the outside of the tripod 610, a double-groove synchronous pulley is fixed to the outside of one demolding rod 620, and single-groove synchronous pulleys are fixed to the outside of the other two demolding rods 620. A synchronous belt is connected between the single-groove synchronous pulley and the double-groove synchronous pulley, thereby realizing the connection between the adjacent two demolding rods 620 through the synchronous belt transmission. In this embodiment, during the mold closing process, the demolding rod 620 is inserted into the mold cavity through the demolding hole, and the end face of the demolding rod 620 is flush with the inner wall of the mold cavity. Then, the motor 5 640 drives the multiple demolding rods 620 to rotate so that the end face of the demolding rod 620 is in a rotating and active state inside the mold cavity, which can prevent the injection molding material from sticking to the end face of the demolding rod 620, and then causing the product to be demolded by the demolding rod 620 later, resulting in flash damage at the adhesion point between the product and the end face of the demolding rod 620. During demolding, after the movable mold base 330 leaves the fixed mold base 220, the multiple demolding rods 620 continue to move toward the mold cavity position along the demolding hole, making it convenient to push the top glue block product inside the mold cavity out of the mold.

[0022] like Figure 1 and Figure 2 As shown, in this embodiment, the specific product structure of the top glue block and the structure of the mold cavity are prior art and will not be described here. Figure 3 A plurality of demoulding holes are provided through the interior of the mold cavity, and the demoulding holes facilitate the demoulding rod 620 to be inserted into the interior of the mold cavity to facilitate product demoulding.

[0023] like Figure 6As shown, in this embodiment, a fixed seat is fixed in the middle of the tripod 610. The fixed seat is fixed to the air blowing pipe 800. The air blowing pipe 800 is connected to a device for blowing cold air to the outside (such as a cold air blower) through a hose. The cold air device can blow cold air into the mold cavity through the hose and the air blowing pipe 800, accelerating the heat dissipation of the mold cavity during the injection molding operation, enabling the product to be quickly cooled and solidified. In addition, the blowing is carried out simultaneously when the brush 630 rotates to clean the mold cavity, which also facilitates the quick detachment of the residual dirt cleaned by the brush 630 from the mold cavity, improving the cleaning effect of the mold cavity.

[0024] As Figure 3 and Figure 5 As shown, in this embodiment, a lead screw two 531 rotates inside the guide rail one 530. A transmission block one that is threadedly connected to the outside of the lead screw two 531 and slidably connected to the guide rail one 530 is fixedly connected to the guide rail two 540. A motor three 532 capable of driving the rotation of the lead screw two 531 is fixed to the top of the guide rail one 530. A lead screw three 541 rotates inside the guide rail two 540. A transmission block two that is threadedly connected to the outside of the lead screw three 541 and slidably connected to the guide rail two 540 is fixedly connected to the tripod 610. A motor four 542 capable of driving the rotation of the lead screw three 541 is fixed to one end of the guide rail two 540.

[0025] In this embodiment, the electric slider 520, a component of the prior art, slides back and forth on the slide rail 510, enabling the mold base 500 to move the tripod 610 back and forth. By rotating the lead screw two 531, the transmission block one drives the guide rail two 540 to move up and down, enabling the mold base 500 to move the tripod 610 up and down. By rotating the lead screw three 541, the transmission block two moves left and right along the guide rail two 540, enabling the mold base 500 to move the tripod 610 left and right. Thus, the mold base 500 can adjust the positions of the demolding rod 620 and the injection molding assembly 700 on the tripod 610 back and forth, left and right, and up and down, facilitating the insertion of the demolding rod 620 into the mold cavities at different positions for injection molding standby, and connecting the injection molding assembly 700 to the mold cavities at different positions to convey the injection molding raw materials. Therefore, a single injection molding assembly 700 and a group of demolding rods 620 can be moved to different positions for injection molding operations as needed.

[0026] In this embodiment, referring to Figure 3 , the mold base 500 can insert multiple demolding rods 620 on the tripod 610 into the demolding holes. During this process, multiple brushes 630 on the demolding rods 620 can simultaneously move into the exposed mold cavity. When the demolding rods 620 rotate, the multiple brushes 630 will rotate in the mold cavity, facilitating the cleaning of the residual plastic or dirt inside the mold cavity. During the demolding process, the demolding rods 620 will continue to move towards the mold cavity. At this time, the soft and deformable characteristics of the brushes 630 are utilized to meet the continuous movement of the demolding rods 620 into the mold cavity, facilitating the pushing out of the top-gum products in the mold cavity.

[0027] As Figure 3 and Figure 4 shown, in this embodiment, a first motor 230 capable of driving the stationary mold base 220 to rotate is fixed to the top of the rectangular frame 210. When it is necessary to rotate the stationary mold base 220 to rotate the used mold cavity out for cleaning and standby, first, the moving mold base 330 is separated from the stationary mold base 220, and then the mold base 500 drives the injection molding assembly 700 and a plurality of demolding rods 620 on the tripod 610 to leave the stationary mold base 220, reserving enough space for the subsequent rotation of the stationary mold base 220. Then, the first motor 230 drives the stationary mold base 220 to rotate 180 degrees inside the rectangular frame 210, rotating the used mold cavity to the side close to the brush 630, and rotating the cleaned and standby mold cavity to the side close to the moving mold base 330 for mold closing and standby.

[0028] As Figure 2 and Figure 3 shown, in this embodiment, a second motor 340 capable of driving the first lead screw 320 to rotate is fixed to the top of the column 310. The output end of the second motor 340 drives the first lead screw 320 to rotate forward and backward, so that the moving mold base 330 screwed to the first lead screw 320 can move towards the stationary mold base 220 along the first lead screw 320 for mold closing, or move away from the stationary mold base 220 for demolding.

[0029] In this embodiment, a guide shaft fixed to the rectangular frame 210 is fixed to the top of the column 310. The guide shaft is slidably connected to the moving mold base 330. When the moving mold base 330 moves under the drive of the first lead screw 320, the top of the moving mold base 330 can stably move along the guide shaft, so that the moving mold base 330 can perform mold closing and demolding smoothly.

[0030] As Figure 3 shown, in this embodiment, an aggregate box 400 is placed between the column 310 and the rectangular frame 210. The aggregate box 400 can hold the products that fall after demolding.

[0031] In specific implementation, the mold base 500 will first move the tripod 610 to the outside of a mold cavity, and then insert the demolding rod 620 into the mold cavity to block the demolding hole. The injection molding raw material is conveyed into the mold cavity by means of the injection molding assembly 700. The equipment for pumping the injection molding raw material to the injection molding assembly 700 from the outside is prior art and will not be elaborated here. During the injection molding process, the demolding rod 620 is in a rotating state. After the injection molding, the air blowing pipe 800 can blow cold air to the outside of the mold cavity to accelerate the curing of the product. After the product is cured, the tripod 610 can be adjusted to the positions of the remaining mold cavities by the mold base 500 for the injection molding of the second product. After the demolding rod 620 leaves the demolding hole, the demolding hole conducts the mold cavity to the outside, which is also convenient for the heat inside the mold cavity to dissipate, improving the cooling and fixing effect of the product. Finally, when products are injection molded in multiple mold cavities on one side of the fixed mold base 220, the moving mold base 330 is separated from the fixed mold base 220 for demolding. Of course, during the demolding process, the demolding rod 620 can be inserted into the demolding hole again to assist in pushing out the products that are not easily demolded.

[0032] Embodiment 2, on the basis of Embodiment 1, in order to enable the round hole 621 on the demolding rod 620 to convey the injection molding raw material into the mold cavity and be able to recover the excess injection molding raw material between the round hole 621 and the mold cavity into the round hole 621.

[0033] As Figure 7 and Figure 8 shown, in this embodiment, a round hole 621 is opened at one end of a demolding rod 620, and a frustum-shaped hole 622 communicating with the round hole 621 is opened at the other end of the demolding rod 620. A convex block 623 is fixed inside the round hole 621. The injection molding assembly 700 includes an injection molding cylinder 710 rotatably inserted at one end of the round hole 621. One end of the injection molding cylinder 710 is fixed to the tripod 610. A shaft rod 720 is slidably inserted into the injection molding cylinder 710. A frustum-shaped block 721 is fixed at one end of the shaft rod 720. The frustum-shaped block 721 is adaptively inserted into the frustum-shaped hole 622. An electric push rod 730 is fixed to the outside of the tripod 610, and the electric push rod 730 can drive the shaft rod 720 to move in the round hole 621.

[0034] In this embodiment, during injection molding, the output end of the electric push rod 730 drives the shaft rod 720 to move away from the circular hole 621, separating the frustum-shaped block 721 from the frustum-shaped hole 622. As a result, the raw material pumped into the interior of the injection barrel 710 from the outside through the feed pipe 712 flows into the interior of the mold cavity after mold clamping through the circular hole 621 and the frustum-shaped hole 622. After the mold cavity is filled with the raw material, the output end of the electric push rod 730 shortens, causing the shaft rod 720 to drive the frustum-shaped block 721 to be inserted into the frustum-shaped hole 622, achieving the blocking of the frustum-shaped injection hole. When the frustum-shaped block 721 gradually moves into the frustum-shaped hole 622, the gap between the frustum-shaped block 721 and the frustum-shaped hole 622 gradually decreases, and the excess raw material extruded from the mold cavity can flow back into the circular hole 621 of the demolding rod 620 along this gradually decreasing gap, effectively preventing the phenomenon of raw material residue at the position of the traditional injection hole.

[0035] In this embodiment, a support pipe 711 slidably sleeved with the shaft rod 720 is fixed inside the injection barrel 710. A chute 722 for slidably engaging with the convex block 623 is provided on the outer side of the shaft rod 720, enabling the shaft rod 720 to linearly slide inside the circular hole 621 and also to rotate synchronously as the demolding rod 620 rotates, making the end faces of both the frustum-shaped block 721 and the demolding rod 620 flush with the inner wall of the mold cavity and rotate, effectively preventing the cured raw material from adhering to the frustum-shaped block 721 during the injection molding process.

[0036] In this embodiment, a connection block rotatably connected to the shaft rod 720 is fixed to the output end of the electric push rod 730, enabling the shaft rod 720 to rotate at the output end of the electric push rod 730 and also to linearly move as the output end of the electric push rod 730 extends or shortens. Among them, a heating wire for wire technology components is fixed inside the shaft rod 720. After the heating wire is powered on, it heats the shaft rod 720, causing the raw material remaining in the circular hole 621 of the demolding rod 620 to be in a hot melt state for subsequent continuous injection molding use.
