Abstract
Description
Technical Field
[0001] This utility model relates to the field of die casting molding technology, specifically to a die casting molding equipment for the preform of a twin-screw granulator housing. Background Technology
[0002] The casing of a twin-screw granulator needs to withstand the high temperature, high pressure and continuous friction of the material during the granulation process, which places extremely high demands on structural strength and sealing. Die casting, with the advantage of rapid filling of molten metal under high pressure, can accurately form the complex structure of the casing preforms to meet its precision requirements.
[0003] However, the venting hole diameter of traditional die-casting equipment is fixed, making it difficult to flexibly adjust according to the gas discharge requirements of different parts of the housing preform. During die casting, molten metal flows in complex cavities. In deep cavity areas, the gas volume is large and the discharge path is long. A fixed small orifice diameter can easily lead to venting obstruction and the formation of air pockets. In thin-walled areas, the gas volume is small but needs to be discharged quickly. A fixed large orifice diameter will cause the molten metal to overflow with the gas, forming burrs. This fixed orifice diameter design is difficult to adapt to the venting requirements of different areas, resulting in defects such as looseness and material shortage in the preform, which affects the performance of the housing and the efficiency of subsequent processing. Therefore, there is an urgent need for a twin-screw granulator housing preform die-casting equipment to solve the above problems. Utility Model Content
[0004] The purpose of this utility model is to provide a die-casting molding equipment for the preform of a twin-screw granulator housing, in order to solve the problem mentioned in the background art that the vent holes of the die-casting molds of traditional die-casting molding equipment are mostly set with fixed diameters, making it difficult for the gas inside the mold to be discharged adaptively when die-casting the preform of the twin-screw granulator housing.

[0020] 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.
[0021] Please see Figures 1-3 This utility model provides a die-casting molding equipment for a twin-screw granulator housing preform, including a molding machine body 1, with an upper mold and a lower mold on the surface of the molding machine body 1, and a gas discharge component 2 disposed on the surface of the upper mold for adaptively discharging gas inside the mold during die casting, an adjustment component 3 disposed on the inner wall of the gas discharge component 2 for adjusting the adaptive initial force according to the die casting gas pressure, and a constraint component 4 disposed on the inner wall of the gas discharge component 2 for constraining the movement direction of the moving parts inside the gas discharge component 2. The gas discharge component 2 allows for adaptive discharge of gas between the upper and lower molds during the die-casting of the twin-screw granulator housing preform, based on pressure, thereby improving the die-casting effect. Simultaneously, the adjustment component 3 allows for adjustment of the initial force of the adaptive discharge from the gas discharge component 2 according to the gas pressure during die-casting, enhancing the overall practicality of the die-casting equipment. Furthermore, the constraint component 4 constrains the movement direction of the internal moving parts of the gas discharge component 2, ensuring the stability of gas discharge during die-casting.
[0022] Furthermore, the gas discharge assembly 2 includes a main tube 201, which is fixedly connected to the top surface of the upper mold. The surface of the main tube 201 has an exhaust hole 202. A baffle block 203 is slidably connected to the inner wall of the main tube 201. A compression spring 204 is provided on the top surface of the baffle block 203. A limit groove 205 is formed in the inner wall of the main tube 201. The surface of the baffle block 203 is slidably connected to the inner wall of the limit groove 205. A fixing bracket 206 is fixedly connected to the surface of the main tube 201 and is fixedly connected to the top surface of the upper mold. Through the gas discharge assembly 2, the exhaust hole 202 is formed. During die casting, gas enters the interior of the main tube 201 and compresses the blocking block 203, causing the spring 204 to contract and deform. The blocking block 203 moves, allowing the gas between the upper and lower molds to be discharged adaptively according to the pressure, thereby improving the die casting effect. The limiting groove 205 is provided to limit the movement distance of the blocking block 203, thereby preventing the blocking block 203 from sliding down. The fixing frame 206 is provided to facilitate auxiliary positioning of the main tube 201, thereby improving the stability of the main tube 201 during use.
[0023] Furthermore, the adjustment component 3 includes an adjustment threaded post 301, which is disposed on the inner wall of the main tube 201. The inner wall of the main tube 201 has a threaded hole 302. The surface of the adjustment threaded post 301 is threadedly connected to the inner wall of the threaded hole 302. The bottom surface of the adjustment threaded post 301 abuts against the upper end of the compression spring 204. Through the adjustment component 3, the adjustment threaded post 301 rotates to compress the compression spring 204, causing the compression spring 204 to deform. This facilitates the adjustment of the initial force of the gas discharge component 2 to adaptively discharge according to the gas pressure of the die casting process, thereby improving the overall practicality of the die casting equipment.
[0024] Furthermore, the constraint component 4 includes a sliding post 401, which is fixedly connected to the upper end of the blocking block 203. The upper end of the adjusting threaded post 301 is provided with a constraint hole 402. The surface of the sliding post 401 is slidably connected to the inner wall of the constraint hole 402. Through the constraint component 4, the constraint hole 402 constrains the sliding post 401, thereby facilitating the parallel up and down movement of the blocking block 203 and ensuring the stability of gas discharge during die casting.
[0025] Working principle: During use, the gas discharge component 2 allows gas to enter the main tube 201 during die casting, compressing the blocking block 203 and causing the spring 204 to contract and deform. At the same time, the blocking block 203 moves according to the air pressure. The movement of the blocking block 203 facilitates the adaptive discharge of gas between the upper and lower molds according to the pressure, thereby improving the die casting effect.
[0026] Meanwhile, the adjustment component 3 allows the adjustment threaded column 301 to rotate and compress the compression spring 204, causing the compression spring 204 to deform. This facilitates the adjustment of the initial force of the gas discharge component 2 according to the gas pressure of the die casting process, thereby improving the overall practicality of the die casting equipment.
[0027] Secondly, the constraint component 4 is set to constrain the sliding column 401 by the constraint hole 402, thereby facilitating the parallel up and down movement of the blocking block 203 and ensuring the stability of gas discharge during die casting.
[0028] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention.
