Description

Technical Field

[0001] This utility model relates to the field of mold technology, specifically a two-color mold with inclined guide pillars and a slider mechanism. Background Technology

[0002] Most plastic products are formed by injection molds. Injection molds can efficiently form plastic products of the required shape, thus accelerating the development of injection molds. Two-color injection molding refers to the process of making finished products with different colors or different types of plastics into finished products with different surface hardness through injection molding. On a two-color mold special machine, the product is first packaged inside. After completion, the moving mold rotates or moves to another fixed mold, and then the product is packaged outside. In this way, the product has two colors inside and outside.

[0003] A search revealed that the utility model patent with Chinese patent number "CN216658690U" discloses a two-color injection molding technology, specifically a device for achieving two-color molding with a single mold. This device solves the problem that traditional rotary two-color parts are top-and-bottom overlapping parts, relying on a large melting area to ensure adhesion, and requiring two molds and a standard two-color injection molding machine, resulting in relatively high mold and injection molding costs. The single-mold two-color molding device includes a base with a cavity at the top, a lower mold inside the cavity at the top of the base, and an upper mold that mates with the lower mold at the top of the lower mold. The lower and upper molds each have casting cavities inside. The two sides of the lower mold are rotatably connected to the two inner sidewalls of the cavity, and the lower and upper molds are detachably connected. This utility model requires only one mold to complete two-color molding, improves the connection quality of two-color castings, and reduces injection molding costs.

[0004] Since the device injects molten plastic into the mold and then cools and solidifies it to produce the required parts, the parts are tightly fitted into the mold cavity after the plastic parts are solidified. At the same time, the mold surface is not smooth, which causes the plastic to stick to the inner wall to a certain extent, making it difficult to remove the parts quickly. Therefore, a two-color mold with inclined guide pillars and slider mechanism is proposed to solve the above-mentioned problems. Utility Model Content

[0005] To address the shortcomings of existing technologies, this utility model provides a two-color mold with inclined guide pillars and a slider mechanism, which has advantages such as easy removal of parts. It solves the problem that when the device injects molten plastic into the mold and then cools and solidifies it to produce the required parts, the parts are tightly attached to the mold cavity after solidification, and the mold surface is not smooth, causing the plastic to stick to the inner wall to a certain extent, making it difficult to remove the parts quickly.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a two-color mold with a slanted guide post and a slider mechanism, comprising an operating block, a worktable fixedly installed on the inner bottom wall of the operating block, a movable block rotatably installed on the top of the worktable, an auxiliary component installed inside the operating block, and a reset component installed inside the worktable;

[0007] The auxiliary component includes an active cavity opened in the top wall of the operating block. A hydraulic cylinder is fixedly installed in the top wall of the active cavity. A moving plate is fixedly installed in the drive end of the hydraulic cylinder. Two auxiliary springs are fixedly installed in each of the left and right inner walls of the active cavity. A connecting plate is fixedly installed between each pair of auxiliary springs. Two vertical plates are fixedly installed at the bottom of the moving plate. A pulley is fixedly installed on the opposite side of the two vertical plates. An inclined guide post body is movably installed on the opposite side of the two connecting plates. Fastening bolts are threaded to the four corners of the two inclined guide post bodies. The active block has a mold cavity and two insertion cavities. A slider body is slidably installed in each of the two insertion cavities.

[0008] The reset assembly includes two rectangular slots inside the movable block, and a reset spring is fixedly installed on the inner wall of each of the two rectangular slots. A connecting block is fixedly installed on the top of each of the two slider bodies.

[0009] Preferably, the top of the worktable is provided with an injection hole, which is connected to the mold cavity.

[0010] Preferably, the mold cavity is located between two slider bodies, and both inclined guide pillar bodies are connected to the connecting plate by four fastening bolts.

[0011] Preferably, the opposite sides of the two connecting blocks are fixedly connected to one end of the return spring.

[0012] Preferably, both insertion cavities are adapted to the inclined guide post body, and both insertion cavities are on the same horizontal plane as the inclined guide post body.

[0013] Preferably, the bottoms of both connecting plates are slidably connected to the top surface of the workbench, and both pulleys are slidably connected to the surface of the connecting plates, and the surfaces of both connecting plates are set as arc surfaces.

[0014] Preferably, the workbench has an internal mounting cavity, and a motor is fixedly installed inside the mounting cavity, with the output shaft of the motor fixedly connected to the bottom of the movable block.

[0015] Compared with the prior art, the technical solution of this application has the following beneficial effects:

[0016] 1. This two-color mold with inclined guide pillars and a slider mechanism, through the cooperation between auxiliary components and reset components, allows the hydraulic cylinder to drive the moving plate upward when the product needs to be injection molded. This causes the two inclined guide pillars to move to opposite sides, thereby squeezing the two slider bodies and extruding the injection-molded plastic. After the injection molding and cooling are completed, the hydraulic cylinder drives the moving plate downward, thereby using the elastic force of the reset spring to push the slider bodies to separate, opening the mold cavity for core pulling and demolding. This achieves rapid removal of the molded parts and improves production efficiency.

[0017] 2. This two-color mold with inclined guide pillars and a slider mechanism, by setting fastening bolts, allows the inclined guide pillars to be disassembled and replaced after prolonged use due to wear on their surfaces. This ensures that the inclined guide pillars maintain good guiding performance and guarantee the accuracy and stability of the injection molding process. Attached Figure Description

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0025] Please see Figure 1-5 In this embodiment, a two-color mold with a slanted guide post and a slider mechanism includes an operating block 1. A workbench 2 is fixedly installed on the inner bottom wall of the operating block 1. A movable block 3 is rotatably installed on the top of the workbench 2. An auxiliary component 4 is installed inside the operating block 1. A reset component 5 is installed inside the workbench 2. An installation cavity is opened inside the workbench 2, and a motor 7 is fixedly installed inside the installation cavity. The output shaft of the motor 7 is fixedly connected to the bottom of the movable block 3.

[0026] It should be noted that two-color injection molding refers to a process in which two different colors or types of plastics are used to create finished products with different colors or different surface hardness through injection molding. For example, when making two-color keycaps or mice, a special two-color molding machine is used to package the inner product first. After completion, the moving mold is rotated 180 degrees to package the outer product. In this way, the product has two colors, inside and outside.

[0027] The auxiliary component 4 includes an active cavity 401 opened in the inner top wall of the operating block 1. A hydraulic cylinder 402 is fixedly installed in the inner top wall of the active cavity 401. A moving plate 403 is fixedly installed at the drive end of the hydraulic cylinder 402. Two auxiliary springs 404 are fixedly installed on the left and right inner walls of the active cavity 401. A connecting plate 405 is fixedly installed between each pair of auxiliary springs 404. Two vertical plates 406 are fixedly installed at the bottom of the moving plate 403. A pulley 407 is fixedly installed on the opposite side of the two vertical plates 406. An inclined guide post body 408 is movably installed on the opposite side of the two connecting plates 405. Fastening bolts 409 are threadedly connected to the four corners of the two inclined guide post bodies 408. The active block 3 has a mold cavity 410 and two insertion cavities 411. A slider body 412 is slidably installed in the two insertion cavities 411. An injection hole 6 is opened at the top of the worktable 2. The injection hole 6 is connected to the mold cavity 410.

[0028] Specifically, when the product needs to be injection molded, the hydraulic cylinder 402 can drive the moving plate 403 to move upward, so that the two inclined guide pillar bodies 408 move to the opposite side, thereby squeezing the two slider bodies 412, and thus squeezing the injection molded plastic. After the injection molding is cooled, the hydraulic cylinder 402 drives the moving plate 403 to move downward, thereby using the elastic force of the return spring 502 to push the slider body 412 to separate, opening the mold cavity 410, so as to facilitate core pulling and demolding.

[0029] Specifically, throughout the entire operation, the design of the inclined guide post body 408 and the slider body 412 ensures the smooth progress of two-color injection molding and the high-quality output of products. The inclined guide post body 408 guides the slider body 412 to perform the core-pulling action at the correct time and position through precise guidance. The slider body 412 is responsible for maintaining the integrity of the cavity during the injection molding process and pulling it out at the appropriate time so that the product can be demolded smoothly. The inclined surfaces of the inclined guide post body 408 and the slider body 412 are compatible.

[0030] The reset assembly 5 includes two rectangular slots 501 inside the movable block 3. A reset spring 502 is fixedly installed on the inner wall of each of the two rectangular slots 501. A connecting block 503 is fixedly installed on the top of each of the two slider bodies 412.

[0031] Specifically, the automatic return of the movable block 3 can be achieved by setting the reset spring 502.

[0032] Both inclined guide post bodies 408 are connected to the connecting plate 405 by four fastening bolts 409.

[0033] Specifically, after prolonged use, the surfaces of the two inclined guide pillar bodies 408 will experience wear. The inclined guide pillar bodies 408 can be disassembled and replaced by turning the fastening bolts 409, which can maintain good guiding performance and ensure the accuracy and stability of the injection molding process.

[0034] In summary, this two-color mold with inclined guide pillars and a slider mechanism, through the cooperation between the auxiliary component 4 and the reset component 5, allows the hydraulic cylinder 402 to drive the moving plate 403 upward when the product needs to be injection molded. This causes the two inclined guide pillar bodies 408 to move to opposite sides, thereby squeezing the two slider bodies 412 and extruding the injection-molded plastic. After the injection molding and cooling are completed, the hydraulic cylinder 402 drives the moving plate 403 downward, thereby using the elastic force of the reset spring 502 to push the slider body 412 apart, opening the mold cavity 410 for core pulling and demolding. This achieves rapid removal of the molded parts and improves production efficiency.

[0035] Furthermore, by setting the fastening bolts 409, after the two inclined guide pillar bodies 408 have been used for a long time, the surface of the inclined guide pillar bodies 408 will be worn. The inclined guide pillar bodies 408 can be disassembled and replaced by turning the fastening bolts 409, so that the inclined guide pillar bodies 408 can maintain good guiding performance and ensure the accuracy and stability of the injection molding process.
