Description

Technical Field

[0001] The utility model relates to the technical field of ceramic casting, and particularly relates to a directional injection mold device for producing ceramic containers. Background Art

[0002] Ceramics is the general term for pottery, stoneware and porcelain. The main material of ceramics is clay. In order to increase the beauty of porcelain, metals or glass are added for decoration. Different soil materials have a great impact on the subsequent finished pottery. The production and processing process of ceramics includes multiple processes, such as the preparation of injection fluid, the injection molding casting of the fluid, calcination and finishing processing. The production of modern ceramics has been transformed from the traditional manual shaping method to a large-scale combined injection molding production method.

[0003] However, when the existing directional injection mold casting equipment for producing ceramic containers is in use, the casting fluid is prone to cooling and solidifying to block the pipeline, and the supply speed of the cooled casting fluid is not uniform enough. Air bubbles are easily accumulated inside the injection fluid, which has a great impact on the subsequent ceramic products. In addition, the existing directional injection mold casting equipment for producing ceramic containers generally relies on manual mold opening, and the mold is extremely easy to scratch the surface of the ceramic container during the mold opening process, which is not conducive to the development of ceramic enterprises. Summary of the Utility Model

[0004] In view of the above technical problems, the utility model provides a directional injection mold device for producing ceramic containers.

[0005] The technical solution of the utility model is as follows: A directional injection mold device for producing ceramic containers, which includes a lower mold, a mold sleeve movably clamped on the upper end of the lower mold, an upper mold arranged on the upper end face of the mold sleeve, a core movably clamped on the upper end face of the lower mold and located inside the mold sleeve, 4 sliders movably clamped on the upper end face of the lower mold and located in the circumferential direction of the core, and an injection mold box movably arranged on the upper end face of the upper mold; a pouring hole is arranged through the top end of the upper mold, and a pouring tube inserted into the pouring hole is arranged on the lower bottom surface of the injection mold box.

[0006] Further, a cavity is arranged at the lower end inside the lower mold, and a liquid injection pipe and a liquid discharge pipe penetrating the lower mold are arranged inside the cavity; the core is movably connected with the lower mold through bolts, and a flow channel respectively communicated with the liquid injection pipe and the liquid discharge pipe is arranged inside the core;

[0007] Explanation: By arranging a flow channel respectively communicated with the liquid injection pipe and the liquid discharge pipe inside the core, the coolant can be injected into the flow channel through the liquid injection pipe, which is convenient for cooling and shaping the ceramic container after injection molding.

[0008] Further, a positioning hole is arranged on the upper end face of the lower mold, and a limit pin movably inserted into the positioning hole is arranged on the lower bottom surface of the mold sleeve;

[0009] Description: Inserting the membrane sleeve into the positioning hole on the lower mold by using the limit pin is beneficial to improve the connection stability between the membrane sleeve and the lower mold and avoid the phenomenon of mold flashing during the casting process of the ceramic container.

[0010] Furthermore, a first hydraulic cylinder connected to the membrane sleeve is arranged on the side wall of the lower mold;

[0011] Description: By arranging the first hydraulic cylinder, it is convenient to separate the membrane sleeve from the lower mold.

[0012] Furthermore, sliding grooves are arranged on the upper end surface of the lower mold corresponding to the positions of the respective sliders, and the respective sliders are respectively slidably clamped with the sliding grooves at the corresponding positions through sliding seats; notches are arranged on both sides of the lower bottom surface of the membrane sleeve, and second hydraulic cylinders located inside the two notches are arranged on both sides of the upper end surface of the lower mold. Push rods are arranged at the output ends of the two second hydraulic cylinders, and the two push rods are respectively slidably clamped with the two sliders on the same side;

[0013] Description: After the casting of the ceramic container is completed, use the second hydraulic cylinder to pull the corresponding push rod, so that the corresponding slider slides in the sliding groove, and finally make the respective sliders move away from each other, which not only improves the convenience of demolding the ceramic container, but also is beneficial to improve the connection stability between the slider and the lower mold.

[0014] Furthermore, a driving motor is arranged at the top end of the injection mold box, the output shaft of the driving motor penetrates through the injection mold box, and a heating mesh plate is arranged on the output shaft;

[0015] Description: Using the driving motor to drive the heating mesh plate to rotate inside the injection mold box can not only heat-treat the casting fluid in the injection mold box and improve the directivity when the casting fluid flows through the injection pipe and enters the outside of the core; at the same time, the rotating heating mesh plate can stir the casting fluid to avoid generating bubbles inside the casting fluid, thereby improving the forming effect of the ceramic container.

[0016] Furthermore, heat dissipation holes are arranged through the side wall of the membrane sleeve;

[0017] Description: By arranging heat dissipation holes on the membrane sleeve, it is beneficial to quickly discharge the heat inside the membrane sleeve, which promotes the cooling and shaping of the ceramic container and improves the working efficiency of the equipment.
