Description

Technical Field

[0001] This utility model relates to the field of thermoplastic elastomer production technology, and in particular to a novel cooling molding equipment for thermoplastic elastomer production. Background Technology

[0002] Novel thermoplastic elastomers (TPEs) are a class of polymeric materials that combine the elastic properties of thermoplastics and rubber. They can soften and be molded when heated like plastics, while also possessing the elasticity and flexibility of rubber. They are widely used in the automotive, electronics, and medical fields. The production process of novel TPEs typically includes steps such as raw material mixing, melt extrusion, and cooling molding. During the production process, cooling molding equipment is used to rapidly reduce the material temperature to ensure that the TPE solidifies and maintains its elastic properties, while avoiding deformation. The benefits of using cooling molding equipment include improved production efficiency, guaranteed product dimensional accuracy, improved surface quality, and avoidance of material performance degradation caused by overheating.

[0003] Cooling molding equipment in the production of new thermoplastic elastomers (TPEs) typically works by combining forced cooling and mold cooling. During the molding process, the molten thermoplastic elastomer material enters the mold cavity through an extruder or injection molding machine, and then the temperature is controlled by the cooling system inside the mold. The cooling system uses circulating cooling water or air to quickly remove heat through the cooling channels inside the mold, so that the material cools and solidifies in the mold, ensuring the dimensional stability and surface quality of the molded product.

[0004] In existing technologies, some cooling molding equipment for the production of novel thermoplastic elastomers lacks automatic feeding and unloading mechanisms, resulting in a significant time consumption during the feeding and unloading processes, which reduces work efficiency. Furthermore, since the equipment cannot simultaneously cool the thermoplastic elastomer from both the top and bottom, uniform cooling cannot be achieved, leading to uneven cooling. This, in turn, affects the properties of the thermoplastic elastomer after cooling and plasticization, reducing product quality and production efficiency. Therefore, a novel cooling molding equipment for the production of thermoplastic elastomers is proposed to solve the above problems. Utility Model Content

[0025] Reference Figure 1 , Figure 2This utility model provides an embodiment of a novel cooling molding device for thermoplastic elastomer production, comprising a housing 1. The housing 1 serves as the external frame of the entire device, providing support and protection, and housing an automatic feeding mechanism. The housing 1 is made of a high-temperature resistant and corrosion-resistant metal to adapt to the high-temperature working environment during the thermoplastic elastomer production process. Two sliding support blocks 2 are fixedly connected to the top of the housing 1. The sliding support blocks 2 support and guide the sliding movement of the connected automatic feeding mechanism, adjustable cooling mechanism, and other equipment, ensuring the smooth operation of each component. The two sliding support blocks 2 are fixedly connected to both sides of the housing 1. The automatic feeding mechanism is slidably connected to the side of the two sliding support blocks 2 closest to each other, delivering the thermoplastic elastomer injected into the mold to the cooling mechanism for cooling and plasticization, thereby improving the working efficiency of the device. The top of the sliding support blocks 2... All are fixedly connected to an adjustable cooling mechanism. The adjustable cooling mechanism controls the flow rate and temperature of the cooling fluid to regulate the cooling rate of the thermoplastic elastomer during the molding process, thereby controlling the quality and performance of the finished product. An automatic feeding mechanism is slidably connected inside the shell 1 to automatically push the plasticized thermoplastic elastomer out of the device, thereby further improving the working efficiency of the device. A lower cooling block 9 is fixedly connected to one side of the sliding support block 2. The lower cooling block 9 has multiple cooling grooves inside. The lower cooling block 9 cooperates with the adjustable cooling mechanism to quickly cool the thermoplastic elastomer, thereby ensuring working efficiency.

[0026] The adjustable cooling mechanism includes an adjusting support block 3. The adjusting support block 3 allows for precise positioning of the cooling block through the adjustment of the lead screw 6 and the sliding adjusting block 7 to adapt to different production needs. The adjusting support block 3 is fixedly connected to the top of the sliding support block 2. An adjusting drive mechanism is fixedly connected to the top of the adjusting support block 3. The adjusting drive mechanism is used to drive the adjusting system in the adjustable cooling mechanism to adjust the position of the cooling block. The lead screw 6 is rotatably connected inside the adjusting support block 3. Through the external thread, the sliding adjusting block 7 is pushed to reciprocate under the adjustment of the rotation of the lead screw 6. The sliding adjusting block 7 is slidably connected to the outside of the lead screw 6 to control the upper cooling block, so that the upper cooling block follows the sliding adjusting block 7 to reciprocate, thereby cooling the thermoplastic elastomer. An upper cooling block 8 is fixedly connected to the side of the sliding adjusting block 7. A cooling water circulation mechanism is fixedly connected to the left side of the upper cooling block 8. Multiple upper push shafts 10 are fixedly connected to the bottom of the upper cooling block 8.

The water in the cooling water tank 24 is pushed by the water pump 12 and transmitted to the cooling block 8 and the thermoplastic elastomer mold 13 through the upper cooling water supply pipe 11 and the lower cooling water supply pipe 22. Cooling water returns to the water tank and is recirculated through the upper cooling water return pipe 21 and the lower cooling water return pipe 23. The flow rate and pressure of the water pump 12 can be adjusted to ensure the flexibility of the cooling system;

[0028] The adjustment drive mechanism includes a motor support frame 4, which is fixedly connected to the top of the adjustment support block 3. An adjustment motor 5 is fixedly connected inside the motor support frame 4, and a lead screw 6 is fixedly connected to the bottom of the motor support frame 4. Power is provided by the adjustment motor 5, driving the lead screw 6 to rotate. The lead screw 6 then transmits the rotational force to the adjustment support block 3, thereby moving the sliding adjustment block 7 and adjusting the position of the cooling block 8. This ensures that the cooling block can be precisely adjusted during each production process.

[0029] Reference Figure 1 , Figure 3 , Figure 4 The automatic feeding mechanism includes a thermoplastic elastomer mold 13, which is the core component used to carry thermoplastic elastomer material and cool and mold it. The thermoplastic elastomer mold 13 is slidably connected to one side of two sliding support blocks 2. An installation groove is provided on the left side of the thermoplastic elastomer mold 13. A rack 14 is fixedly connected inside the installation groove. A transmission gear 15 is rotatably connected inside the sliding support block 2. The rack 14 and the transmission gear 15 cooperate with each other. Under the drive of the mold drive motor 17, the transmission gear 15 is rotated, thereby causing the rack 14 to reciprocate. The mold drive motor 17 is fixedly connected inside the transmission gear 15. The mold drive motor 17 serves as a power source to drive the transmission gear 15 to rotate, enabling the transmission gear 15 to run stably. A motor support block 16 is fixedly connected to the bottom of the mold drive motor 17 as a support to ensure that the mold drive motor 17 can work stably. The motor support block 16 is fixedly connected to the left side of the housing 1. A sliding groove is provided inside the sliding support block 2, and the thermoplastic elastomer mold 13 is slidably connected in the sliding groove.

[0030] The automatic unloading mechanism includes four electric push rods 18, which provide pushing force to assist multiple mold unloading push shafts 20 fixed to the top of the mold unloading support block 19 in reciprocating motion, thereby ensuring stable automatic unloading operation. The four electric push rods 18 are fixedly connected to the four corners inside the housing 1, and the top of the four electric push rods 18 is fixedly connected to the mold unloading support block 19. The mold unloading support block 19 supports and pushes the cooled and formed thermoplastic elastomer out of the mold through the interface with the lower cooling block 9. Multiple mold feeding push shafts 20 are fixedly connected to the top of the mold feeding support block 19. The mold feeding push shafts 20 are used to push the molded thermoplastic elastomer material out of the mold and send it to the lower cooling block 9 for further cooling. The multiple mold feeding push shafts 20 correspond one-to-one with the cooling grooves opened inside the lower cooling block 9. The upper push shaft 10 corresponds one-to-one with the cooling grooves opened inside the lower cooling block 9. The bottom of the upper push shaft 10 is provided with a hemispherical groove, and the top of the mold feeding push shaft 20 is provided with a hemispherical groove.

[0031] Working principle: The molten thermoplastic elastomer is injected into the thermoplastic elastomer mold 13. Then, the mold drive motor 17, supported by the motor support block 16 and fixed on the left side of the housing 1, is started, thereby driving the transmission gear 15 to rotate. Then, the rack 14, coupled with the transmission gear 15, reciprocates under the drive of the transmission gear 15, thereby driving the thermoplastic elastomer mold 13 to slide. When the thermoplastic elastomer mold 13 corresponds to the lower cooling block 9, the adjusting motor 5, which is fixedly connected to the top of the adjusting support block 3 by the motor support frame 4, is started. Then, the lead screw 6 is rotated under the drive of the adjusting motor 5. Then, the sliding adjusting block 7 is driven by the thread on the outside of the lead screw 6 to reciprocate, and then the upper cooling block 8 is driven to reciprocate. With the cooperation of multiple upper pushing shafts 10 fixedly connected to the bottom of the upper cooling block 8, the upper pushing shafts 10 contact the thermoplastic spring body inside the thermoplastic elastomer mold 13 and push the thermoplastic elastomer down and fall into the interior of the lower cooling block 9.

[0032] After the thermoplastic elastomer falls into the lower cooling block 9, the water pump 12 starts, and the cooling water in the cooling water tank 24 is injected into the upper cooling block 8 and the lower cooling block 9 through the upper cooling water supply pipe 11 and the lower cooling water supply pipe 22, thereby completing the cooling and plasticization of the thermoplastic elastomer. At the same time, the cooling water in the upper cooling block 8 and the lower cooling block 9 is returned to the cooling water tank 24 through the upper cooling water return pipe 21 and the lower cooling water return pipe 23, thereby ensuring the stability and consistency inside the upper cooling block 8 and the lower cooling block 9, and thus improving the plasticization effect.

[0033] After the thermoplastic elastomer cools and plasticizes, the electric push rod 18 is activated, which drives the mold unloading support block 19 to slide down, and then drives the mold unloading push shaft 20 to slide down, so that the thermoplastic elastomer follows the mold unloading push shaft 20 down. Then the mold drive motor 17 is activated, which drives the transmission gear 15 to rotate. Then the transmission gear 15 drives the rack 14 to move, and then drives the thermoplastic elastomer mold 13 to move. After that, the electric push rod 18 is activated, pushing the mold unloading support block 19 to slide up, and then pushing the mold unloading push shaft 20 and the thermoplastic elastomer to slide up. When the thermoplastic elastomer mold 13 aligns with the lower cooling block 9 next time, the thermoplastic elastomer that has been cooled and plasticized in the previous time is pushed out of the device.

[0034] 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.
