Description

Technical Field

[0001] This utility model relates to the field of injection mold technology, and in particular to multi-station rubber injection molding mold. Background Technology

[0002] Multi-station rubber injection molding dies are widely used in the rubber product manufacturing industry, for manufacturing rubber products related to electrical insulation parts, shock-absorbing pads, and shoe soles. Their working principle involves injecting thermoplastic and thermosetting rubber materials into the mold cavity under high temperature and pressure, followed by vulcanization to obtain the desired rubber product. This technology greatly improves the production efficiency and quality stability of rubber products. Compared to ordinary manual and single-station production methods, it enables continuous and batch production, significantly reducing labor costs and increasing production speed.

[0003] The process of rubber injection molding involves heating and melting rubber raw materials, injecting them into a mold, pressing and heating them for vulcanization, waiting for the vulcanized rubber to cool and solidify, and finally opening the mold to remove the product. The process of preparing the next product can only begin while the mold is being opened and the product is being removed, reducing production efficiency. Existing equipment separates the heating and melting, vulcanization, and mold opening steps by incorporating a mold rotation frame and a plasticizing chamber, allowing multiple steps to proceed without waiting and ensuring process continuity, thus improving production efficiency to some extent. However, these solutions still have shortcomings. They cannot produce multiple products simultaneously, and the lack of stirring during the heating and melting process results in uneven heating of the raw materials, affecting product quality and failing to meet usage requirements. Utility Model Content

[0004] To overcome the above shortcomings, this utility model provides a multi-station rubber injection molding die, which aims to improve the existing technology where only one product can be processed at a time during injection, and the heating and melting of raw materials is not uniform enough, resulting in reduced production efficiency and quality.

[0005] To achieve the above objectives, this utility model adopts the following technical solution: a multi-station rubber injection molding die, including a support frame, a heating box fixedly connected to the top of the support frame, a fixed plate fixedly connected to the rear top of the heating box, a servo motor fixedly connected to the front bottom of the fixed plate, a drive gear fixedly connected to the output end of the servo motor, multiple driven gears meshing with the left and right sides of the outer wall of the drive gear, a spiral blade fixedly connected to the bottom end of both the drive gear and the driven gear, multiple stirring blades fixedly connected to the outer wall of the spiral blade, multiple guide tubes fixedly connected to the left and right sides of the bottom of the heating box, an injection tube fixedly connected to the bottom end of the guide tubes, and a molding mechanism provided at the bottom of the support frame, the molding mechanism being used for rapid molding of the die.

[0006] As a further description of the above technical solution:

[0007] The molding mechanism includes a support platform, the top of which is fixedly connected to the bottom of a support frame. A cylinder is fixedly connected to the top of the inner wall of the support platform, and a lifting plate is fixedly connected to the top of the cylinder. Multiple moving molds are fixedly connected to the top of each lifting plate. A cooling box is fixedly connected to the middle of the front side of the lifting plate. Multiple cooling rods are fixedly connected to the bottom of the inner wall of the cooling box. A water pump is provided on the rear side of the bottom of the inner wall of the cooling box. A water pipe is fixedly connected to the top of the water pump, and a fixed mold is fixedly connected to the bottom of the injection tube.

[0008] As a further description of the above technical solution:

[0009] A feeding plate is fixedly connected to the top front side of the heating box, and a sealing cover is rotatably connected to the top front side of the feeding plate.

[0010] As a further description of the above technical solution:

[0011] An observation window is fixedly connected to the center of the front side of the heating box, and a sealing strip is fixedly connected to the front edge of the observation window.

[0012] As a further description of the above technical solution:

[0013] Multiple reinforcing blocks are fixedly connected to the bottom of the outer wall of the support frame, and a reinforcing plate is fixedly connected to the middle of the inner wall of the support platform.

[0020] This utility model has the following beneficial effects:

[0021] 1. In this utility model, a heating box is used to heat and melt the raw materials. At the same time, a servo motor is started to drive the active gear and the driven gear to rotate, which in turn drives the stirring blades on the spiral blades to stir the raw materials. Since the direction of the central spiral blade and the left and right spiral blades are opposite, the raw materials will not be injected. After the heating is uniform, the motor reverses and the raw materials enter the injection tube through the guide tube, realizing multi-station injection, improving efficiency and ensuring uniform melting of the raw materials.

[0022] 2. In this utility model, the cylinder on the support platform is activated, causing the lifting plate to slide on the support frame, thereby achieving the docking of the moving mold and the fixed mold. After the raw material is injected and melted, the coolant is injected into the cavity of the moving mold through the cooling rod and water pump in the cooling box for rapid cooling and molding. The coolant can be pumped back for recycling, which improves work efficiency, reduces material costs, and meets the requirements of injection molding. Attached Figure Description

[0032] Specifically, the support frame 1 is the basic structure of the entire equipment, characterized by its stability and durability. The heating box 3 is used to provide a heat source to ensure that the material reaches the required temperature to melt during processing. The fixed plate 4 provides a connection platform for the servo motor 5, which is the power source of the entire equipment and can precisely control the movement of the equipment. The drive gear 6 is the core component of the transmission, driving multiple driven gears 7 to transmit the power of the motor to the spiral blades 8. These spiral blades 8 can push the material forward. When the spiral blades 8 reverse, they drive the connected stirring blades 9 to move, ensuring the uniformity of the material heating and melting.

This molding mechanism 2 is specifically designed for rapid mold molding, which can efficiently mold the heated and mixed material into the final product.

[0033] Please see the appendix Figure 1 Appendix Figure 3 and attached Figure 4The molding mechanism 2 includes a support platform 201.

[0034] Specifically, a cylinder 202 is connected to the support platform 201. The cylinder 202 drives the lifting plate 203 at the top to move, causing multiple moving molds 204 at the top of the lifting plate 203 to rise and fall, thereby carrying out the required production process. Multiple cooling rods 206 are evenly fixedly connected to the bottom of the inner wall of the cooling box 205. They are used to cool the product during the molding process and speed up the molding efficiency. A water pump 207 is connected to a water pipe 208 to deliver coolant to the moving molds 204. The fixed mold 209 cooperates with the moving molds 204 during the molding process to complete the product molding work.

[0035] Please see the appendix Figure 1 Appendix Figure 3 and attached Figure 5 A feeding plate 12 is fixedly connected to the top front side of the heating box 3.

A reinforcing plate 17 is fixedly connected to the middle inner wall of the support platform 201.

[0036] Specifically, the feeding plate 12 on the heating box 3 is securely connected, ensuring the convenience of adding raw materials. The sealing cover 13 can seal the box, making the heating process more efficient. The observation window 14 ensures that personnel can clearly observe the remaining raw materials in the box. The sealing strip 15 ensures that the environment inside the box can be well sealed during the heating process. These reinforcing blocks 16 provide additional structural strength for the support frame 1. The reinforcing plate 17 further enhances the stability and durability of the support platform 201.

[0037] Please see the appendix Figure 1A controller 18 is fixedly connected to the front right side of the support platform 201. A display screen 19 is fixedly connected to the front left side of the controller 18. Multiple buttons 20 are fixedly connected to the top right side of the front of the controller 18. A power button 21 is fixedly connected to the bottom right side of the front of the controller 18. A support plate 22 is fixedly connected to the bottom of the support platform 201. Multiple support feet 23 are fixedly connected to the bottom left and right sides of the support plate 22.

[0038] Specifically, the controller 18 on the support platform 201 is securely connected, facilitating personnel control of the equipment. The display screen 19 provides operators with an intuitive information interface, making operation simpler. Buttons 20 allow users to operate independently, ensuring that each structure is processed according to the required process. The power button 21 allows users to turn the power on and off. To ensure the stability of the support platform 201, a support plate 22 is fixedly connected to its bottom. These support feet 23 not only enhance the stability of the support platform 201 but also provide additional height for the equipment, allowing users to have a more comfortable experience when using it.

[0039] Working principle: The raw material is heated and melted by the heating box 3 on the support frame 1. During the melting process, the servo motor 5 fixed on the fixed plate 4 is started, which drives the drive gear 6 at the output end of the servo motor 5 to rotate. The drive gear 6 then drives the driven gear 7 connected to it to rotate, thereby driving the stirring blade 9 on the spiral blade 8 to stir the raw material in the box. Since the spiral blade 8 in the middle and the spiral blades on both sides are set in opposite directions, the gear transmission and direction are also opposite, so that the raw material will not be injected. After uniform heating and melting, the motor reverses, so that the raw material is introduced from the guide tube 10 into the injection tube 11 for multi-station injection operation. This structure can process multiple products at the same time, improve work efficiency, and ensure the uniformity of raw material melting, thus meeting the usage requirements.

[0040] By activating the cylinder 202 fixed on the support platform 201, the lifting plate 203 can slide on the support frame 1, thereby docking the moving mold 204 and the fixed mold 209. After docking, molten raw material is injected. Since the cooling box 205 fixed on the front side of the lifting plate 203 is equipped with a cooling rod 206 to cool the coolant, the water pump 207 in the cooling box 205 can be activated to inject the coolant from the water pipe 208 into the cavity of the moving mold 204, so that the mold can be quickly cooled and formed. After completion, the coolant is pumped back into the box for recycling. This structure can conveniently and quickly cool the mold, improve work efficiency, recover liquid, reduce material costs, and meet the needs of injection molding.

[0041] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model 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 make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
