Description

Technical Field

[0001] This utility model relates to the field of lost foam casting technology, specifically a rapid bonding cold glue device for lost foam casting. Background Technology

[0002] Lost foam casting (LFC) is an advanced casting process, also known as solid foam casting or vapor foam casting. Its core principle involves creating a model using foam plastic (usually polystyrene EPS or copolymer STMMA) that perfectly matches the shape of the casting. A refractory coating is then applied to the model's surface, and the model is embedded in dry sand. Finally, molten metal is poured in, causing the foam model to vaporize and disappear at high temperatures. The molten metal fills the model's cavity, and after cooling, the casting is formed.

[0003] The rapid bonding cold glue device for lost foam casting is a specialized piece of equipment used in the lost foam casting process. It is primarily used to quickly and precisely bond foam plastic models to the gating system. The core function of this device is to improve bonding efficiency, ensure bonding quality, and reduce human error and glue waste. In lost foam casting, the foam model typically needs to be bonded to the gating system to form a complete system. The quality of the bonding directly affects the molding effect and quality of the casting; therefore, the bonding process is crucial. The rapid bonding cold glue device for lost foam casting, through automation, intelligence, and precision control technology, solves the problems of low efficiency, poor consistency, and glue waste associated with traditional bonding methods, significantly improving the production efficiency and product quality of lost foam casting.

[0004] According to the authorization announcement number CN 205254034 U, a lost foam casting device is disclosed, including a gating system and a white mold. The gating system includes a sprue, a runner and an ingate. A buffer device is provided between the sprue and the runner. The buffer device includes a sprue opening connected to the sprue and a runner opening connected to the runner. A buffer recess is provided between the sprue opening and the runner opening.

[0005] The existing lost foam casting process suffers from large errors due to human-assisted adhesive application, making it difficult to ensure consistent adhesive amount and application location for each bonding operation, and resulting in low production efficiency. Therefore, a rapid cold adhesive bonding device for lost foam casting is needed. Utility Model Content

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] This utility model provides: a device for rapid bonding of cold glue in lost foam casting, such as... Figures 1-5 As shown, the device includes a workbench 1, a support frame 2 mounted on the upper part of the workbench 1, a connecting block 5 slidably mounted on the middle of the support frame 2, a fixing block 15 slidably mounted on the side of the connecting block 5, a glue applicator 16 slidably mounted on the middle of the fixing block 15, and two sets of positioning sensors 17 symmetrically mounted on both sides of the fixing block 15. When the device is activated, the positioning sensors 17 will position the mold under the glue applicator 16, and then the electric push rod 6 will push the connecting block 5 to move, thereby moving the mounting frame 11 on the side and the glue applicator 16 to the required glue applicator position to apply glue to the mold 22. By using electric components to drive the glue applicator to move and apply glue, the error caused by manual glue application is reduced, and the product quality is improved while increasing the production efficiency of the product.

[0026] A glue storage tank 18 is installed on the upper part of the support frame 2. A metering pump 19 is installed on the side of the glue storage tank 18. A glue tube 20 is installed at the output end of the metering pump 19. The output end of the glue tube 20 is connected to the input end of the glue application head 16. When the metering pump 19 is started, the glue inside the glue storage tank 18 is drawn into the glue tube 20 and finally into the glue application head 16 to apply glue to the mold 22. The metering pump 19 can record the amount of glue applied in real time. When a certain value is reached, the glue supply will be automatically cut off to avoid glue waste.

[0027] Preferably, the support frame 2 has a movable groove in its middle, and rectangular grooves 3 are respectively formed on both sides of the movable groove in the middle of the support frame 2. A slide plate 4 is installed on the upper part of the two sets of rectangular grooves 3, and a connecting block 5 is installed through the middle of the slide plate 4. The movable groove in the middle of the support frame 2 is used for the movement of the connecting block 5, the rectangular grooves 3 are used to limit the sliding of the slide plate 4, and the connecting block 5 is fixed in the middle of the slide plate 4 and moves together with the slide plate 4.

[0028] Furthermore, an electric push rod 6 is installed on the side of the support frame 2. The output end of the electric push rod 6 passes through the middle of the support frame 2 and is connected to the side of the connecting block 5. The output end of the electric push rod 6 is connected to the side of the connecting block 5 to facilitate the movement of the connecting block 5 and the slide plate 4. According to the position where the mold 22 needs to be glued, the glue applicator 16 is moved to facilitate the glue applicator 16 to apply glue.

[0029] Furthermore, a first groove 7 is provided in the middle of the connecting block 5, a first motor 8 is installed on the top of the connecting block 5, a first screw 9 is installed inside the first groove 7 at the output end of the first motor 8, and a connecting block 10 is installed in the middle of the first screw 9 inside the first groove 7.
