Description

Technical Field

[0001] The present invention relates to the technical field of injection molding for the mouth of a kettle cup, and specifically provides an automated processing device for forming the mouth of a travel kettle cup. Background Art

[0002] The plastic travel kettle cup mouth forming injection molding machine is a highly efficient device specifically used for producing the mouth part of a plastic travel kettle. The injection molding machine can automatically complete processes such as feeding, heating, injection molding, cooling, and demolding, reducing manual intervention, saving labor costs, and increasing product profits. It adopts advanced control technology and a servo drive system to precisely control parameters such as temperature, pressure, and molding time, ensuring product dimensional accuracy and quality stability, making the shape and size of the cup mouth consistent and meeting relevant standards. The heating system uses an energy-efficient heating method and an optimized heating mold, which can quickly heat up to the molding temperature, shorten the production cycle, and reduce energy consumption. At the same time, some models have an automatic waste material collection and processing function, effectively saving raw materials. The injection molding machine is a key device for producing the mouth part of a plastic travel kettle and can efficiently and precisely produce cup mouth components that meet requirements.

[0003] After the existing plastic travel kettle cup mouth is produced by an injection molding machine, it is then manually connected to a stainless steel threaded sleeve. And directly injecting threads requires customizing complex molds, and the manufacturing and maintenance costs of the molds are relatively high. The process of injecting threads is relatively complex and requires longer cooling and demolding times, resulting in an extended production cycle. Moreover, the plastic threads are prone to wear or deformation after being tightened and loosened multiple times, leading to a decrease in sealing performance. Once the threads are damaged, it is difficult to repair, and the entire cup mouth component needs to be replaced, increasing the maintenance cost. The sealing performance of plastic threads is not as good as that of metal threads or seal ring connections, and water leakage is likely to occur. In a high-temperature environment, the sealing performance of plastic threads further deteriorates, and manual connection is difficult to ensure that the connection quality of each product is consistent, and situations of over-tightening or over-loosening are likely to occur. Unstable connection quality causes problems such as water leakage and detachment during the use of the product. Summary of the Invention

Thus, it is convenient to automatically fix the stainless steel threaded sleeve 19 into the injection moving mold 5 without manual intervention, greatly shortening the assembly time of the stainless steel threaded sleeve 19 workpiece, ensuring high-precision docking between the stainless steel threaded sleeve 19 and the mold core column, reducing assembly errors, ensuring the consistency and stability of each product, precise assembly reducing the scrap rate, uniform clamping force and precise positioning reducing the wear of the injection moving mold, and prolonging the service life of the injection moving mold 5.

[0038] The working process of the present invention: When it is necessary to produce the mouth of the travel kettle, first place the stainless steel threaded sleeve 19 between the two clamping jaws 37, control the two clamping hydraulic rods 36 to work through the controller, so that the two clamping hydraulic rods 36 drive the clamping jaws 37 to fix the stainless steel threaded sleeve 19, and control the lifting hydraulic rod 32 to work through the controller. The lifting hydraulic rod 32 drives the lifting platform 33 to descend, and the lifting platform 33 drives the two limit columns three 29 to move steadily downward, thereby driving the stainless steel threaded sleeve 19 to move downward. And control the extrusion hydraulic rod 26 to work through the controller. The extrusion hydraulic rod 26 drives the injection moving mold 5 to move forward through the transfer block 27, so that the moving mold core column 16 moves in front of the stainless steel threaded sleeve 19. Control the two forward movement hydraulic rods 34 to work through the controller. The two forward movement hydraulic rods 34 drive the fixture 35, so that the stainless steel threaded sleeve 19 moves into the inner sleeve groove 20 of the moving mold core column 16. The stainless steel threaded sleeve 19 extrudes the arc surfaces 25 of the several extrusion columns 24, so that the several extrusion columns 24 move in the movable cavity 23.

[0039] Then, air permeability is carried out to the air flow chamber two 22 through the air pressure pipe two 15, so that the gas squeezes several extrusion columns 24, thereby fixing the stainless steel threaded sleeve 19 in the sleeve groove 20. The controller is used to control the clamping hydraulic rod 36 to drive the clamping jaw 37 away from the stainless steel threaded sleeve 19, and then the lifting hydraulic rod 32 is used to drive the fixture 35 back to its original position, so as to conveniently and automatically fix the stainless steel threaded sleeve 19 in the injection molding moving die 5 without manual intervention, greatly shortening the assembly time of the stainless steel threaded sleeve 19 workpiece, ensuring the high-precision docking of the stainless steel threaded sleeve 19 and the mold core column, reducing the assembly error, ensuring the consistency and stability of each product, the precise assembly reducing the rejection rate, the uniform clamping force and precise positioning reducing the wear of the injection molding moving die, and prolonging the service life of the injection molding moving die 5.

[0040] Continue to control the extrusion hydraulic rod 26 to drive the moving die core column 16 and the stainless steel threaded sleeve 19 to move into the injection molding fixed die 4, and air is introduced into the movable groove 10 through the two air pressure pipes one 14 correspondingly, so that the gas pushes the injection molding block 11, and the two injection molding blocks 11 drive the limit column one 12 to move, and the two injection molding blocks 11 stretch the spring 13, and the head 17 of the moving die core column 16 is in movable contact with the end face of the injection molding pipe 3. The injection molding pipe 3 injects the plastic melt of the plastic tank 2 particles into the cup mouth injection cavity 9 through the runner 18 of the head 17, and the plastic melt forms the plastic kettle cup mouth 38 in the cup mouth injection cavity 9, so that the plastic kettle cup mouths 38 are hot melt connected to the stainless steel threaded sleeve 19. The hot melt connection is achieved by heating the plastic melt to a molten state and then fusing it with the surface of the stainless steel threaded sleeve 19, and a firm connection is formed after cooling. This connection method can make full use of the fluidity and plasticity of the plastic to ensure the tight combination of the connection part and further enhance the connection strength. The hot melt connection can achieve a seamless connection between the outside of the plastic kettle cup mouth 38 and the inside of the stainless steel threaded sleeve 19, effectively preventing liquid or gas leakage. Since there is no gap at the connection part, it is not easily affected by corrosive media, improving the service life of the product. As a reinforcing component, the stainless steel threaded sleeve 19 can effectively disperse the external force acting on the plastic kettle cup mouth 38 and prevent it from deforming or cracking due to excessive force. The stainless steel material has excellent corrosion resistance and can resist the erosion of chemical substances, prolonging the service life of the product. The stainless steel threaded sleeve 19 can be conveniently connected with other components with matching threads such as lids and joints to realize the expansion and diversification of functions. The smooth surface and metallic texture of the stainless steel threaded sleeve 19 improve the overall aesthetics of the product, making it look more upscale and durable. And a sealing ring groove 30 is provided on the stainless steel threaded sleeve 19, and it is convenient to install a sealing strip in the sealing ring groove 30 for sealing. The cooperation between the stainless steel threaded sleeve 19 and the sealing strip is closer, and a more effective sealing barrier can be formed to prevent liquid leakage. The plastic threaded sleeve deforms under high temperature or pressure, thus affecting the sealing performance.

[0041] And the injection molding moving mold 5 is controlled by the controller to move out of the injection molding fixed mold 4. With the plastic kettle cup mouth 38 limited by the injection molding block 11, the plastic kettle cup mouth 38 stays in the injection molding fixed mold 4 to release the gas in the movable groove 10. The spring 13 has elastic deformation, thus driving the injection molding block 11 to return to its original position. And the discharging hydraulic rod 6 is controlled by the controller to work. The discharging hydraulic rod 6 drives the collar 7 to move, and the collar 7 drives the ejector pin 8 to eject the plastic kettle cup mouth 38, so as to facilitate the automatic blanking of the plastic kettle cup mouth 38, thus avoiding extrusion, scratching or deformation in manual operation.
