[0033] To enable those skilled in the art to better understand the present application, the technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present application, and not all embodiments. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of the present application.

[0034] The terms "first," "second," etc., in the specification, claims, and accompanying drawings of this application are used to distinguish different objects, not to describe a specific order. Furthermore, the terms "comprising" and "having," and any variations thereof, are intended to cover non-exclusive inclusion. For example, a process, method, system, product, or apparatus that includes a series of steps or units is not limited to the listed steps or units, but may optionally include steps or units not listed, or may optionally include other steps or units inherent to these processes, methods, systems, products, or apparatuses.

[0035] In this document, the term "embodiment" means that a particular feature, structure, or characteristic described in connection with an embodiment may be included in at least one embodiment of this application. The appearance of this phrase in various places throughout the specification does not necessarily refer to the same embodiment, nor is it a separate or alternative embodiment mutually exclusive with other embodiments. It will be explicitly and implicitly understood by those skilled in the art that the embodiments described herein can be combined with other embodiments.

[0036] Currently, according to the traditional fuse manufacturing process, each component of the fuse usually needs to be manufactured independently, involving multiple processes such as material forming, surface treatment, and dimensional precision machining. Complex quality inspection and calibration are also required between processes. Not only is the production process cumbersome, but during the subsequent assembly process, due to the differences in dimensional tolerances and material properties of each component, assembly errors are very likely to occur, affecting the overall performance and reliability of the product.

[0037] To address the aforementioned issues, this application provides a method for manufacturing vertically mounted fuses based on a two-stage molding process. This method can be applied to fuse manufacturing scenarios. By performing two injection molding processes, other components can be directly combined with the pre-made parts, integrating the assembly step into the manufacturing process and improving efficiency. Simultaneously, injection molding ensures that the resulting vertically mounted fuses are integrally formed, avoiding dimensional errors between components that could prevent assembly or reduce quality, thus improving fuse reliability. This solution is applicable to various scenarios, including but not limited to the applications mentioned above.

[0038] The system architecture involved in the embodiments of this application is described below.

[0039] This application provides a fuse manufacturing apparatus 110, which includes a main control module 111 and multiple operating tools (such as...). Figure 1 The main control module 111 determines multiple preparation steps corresponding to the multiple components based on the preparation parameters (operating tools 1, 2 to N). Then, it determines the component type for each component based on these multiple steps. Finally, it generates a control flow table based on the obtained preparation steps and component types. At the start of production, preparation steps that can be prepared in parallel are executed simultaneously according to the execution order in the control flow table, while components that cannot be prepared in parallel are prepared sequentially. At this time, it is only necessary to output the corresponding first control signal to the operating tools required for the multiple parallel preparation steps to control at least one operating tool to execute the corresponding preparation steps in parallel. Then, a second control signal is sent to the operating tools to control them to prepare the components that cannot be prepared in parallel sequentially, ultimately producing the target vertical fuse, thereby improving the fuse preparation efficiency.

[0040] For example, at least one operating tool may include one or more of a robot arm, a lathe, a conveyor, and an injection molding tool, and may also include other tools, without being limited to a single tool.

[0041] Specifically, the number of tools required varies depending on the step. For example, preparing a tube preform requires a robotic arm and injection molding tools, and may also require a conveyor to transport the material, but a lathe is not necessarily needed. Conversely, preparing a conductor requires a robotic arm and a lathe for cutting. Therefore, the appropriate tools can be configured according to the specific preparation steps. Specifically, when generating the control flow chart, corresponding tools can be assigned to each step.

[0042] The specific methods will be described in detail below.

[0043] Please see Figure 2This application also provides a method for manufacturing a vertically mounted fuse based on secondary molding, comprising the following steps:

[0044] Step S201: Obtain the preparation parameters of the target vertical fuse.

[0045] In a specific implementation, the target vertical fuse includes multiple parts, and each part is configured with corresponding manufacturing sub-parameters, that is, the manufacturing parameters include multiple manufacturing sub-parameters.

[0046] Optionally, the vertical fuse manufacturing method based on secondary molding in this embodiment is applied to fuse manufacturing equipment, which can be the main control console or other control equipment in a fuse production line. The manufacturing parameters can be input by the user into the electronic device via an input device, which can be built into the electronic device or an external device; no limitation is made here.

[0047] It is understandable that the fabrication parameters for each part can be configured individually. Therefore, the fabrication order of some decoupled structures among multiple parts may not be unique. The specific fabrication order can be set according to the fabrication order determined in the parameter table as needed.

[0048] Step S202: Determine the preparation steps based on the preparation parameters.

[0049] The preparation steps include the preparation of conductor 30, first molding, preparation of tube preform 10, second molding, and post-processing.

[0050] In practice, based on the user's configuration of manufacturing parameters for each part, corresponding manufacturing steps are generated, including a corresponding manufacturing control flow. The electronic device then controls the corresponding operating tools to execute the corresponding manufacturing steps according to this manufacturing control flow.

[0051] Step S203: When the preparation step is the preparation of conductor 30, the first parameter is obtained from the preparation parameters.

[0052] In specific implementation, multiple components include conductor 30 and base 20 (such as...). Figure 4 The dashed box in the figure represents the portion set on the first connecting portion 312 and the second connecting portion 313 in the conductor 30, as well as the tube blank 10, etc. When it is detected that the current step is to prepare the conductor 30, the first parameter corresponding to the conductor 30 is obtained.

[0053] Step S204: Prepare a conductor according to the first parameter.

[0054] In one possible embodiment, the first parameter includes a first material parameter and a first process parameter; the step of preparing the conductor 30 according to the first parameter includes: controlling an operating tool to perform the following operations: obtaining a first material according to the first material parameter; processing the first material into a conductor 30 of corresponding specifications according to the first process parameter; wherein, as Figure 3 As shown, the conductor 30 includes a molten metal, a first connecting part 312, a second connecting part 313, a first electrode 32 and a second electrode 33. The first electrode 32 is connected to the first end of the molten metal through the first connecting part 312, and the second electrode 33 is connected to the second end of the molten metal through the second connecting part 313.

[0055] In specific implementation, the first material parameters include the type of first material required to prepare the conductor 30 and the corresponding initial specifications of the first material. This first material can be copper, silver, or a copper-silver composite material, or other conductive materials. During production, different first materials are numbered, and different initial specifications of the same first material have different numbers; that is, each specification of the third material has a unique first material number. The main control module determines the first material number, then controls the operating tool to query the corresponding first material's first position based on the first material number, and then picks up the first material from that first position. The first process parameters include the process type and specification parameters used to prepare the conductor. The main control module controls the operating tool to manufacture the first material into a conductor 30 that conforms to the specification parameters.

[0056] The preparation process of conductor 30 will be illustrated below with an example.

[0057] In this example, a long strip of copper material (i.e., the first material) is prepared according to the first material parameters. Then, according to the first process parameters, CNC machining is used to reduce the surface thickness of the material within a specific length at a preset position (such as the middle part) by milling, thinning it to meet the thickness requirements of the molten metal. Then, several rows of through holes are formed at a specific position of the preset position after thinning by die stamping or laser cutting. The lateral spacing between two through holes serves as a fusible neck 321 on the molten metal. Then, using a bending die, the molten metal is bent into a U-shape in the middle, forming a horizontal part 322 and two first vertical parts 323 and second vertical parts 324 on both sides. Preferably, no neck 321 is provided on the horizontal part 322, and the necks 321 on the first vertical parts 323 and second vertical parts 324 are not on the same horizontal plane, i.e., they are staggered. After the conductor 30 is bent, the two ends are on the same horizontal plane, serving as end electrodes (first electrode 32 and second electrode 33). Finally, the conductor 30 that meets the design requirements is obtained by overall tin plating or tin plating the end electrode positions.

[0058] The horizontal section 322 does not have a narrow neck 321, which can prevent the risk that the melting of the narrow neck 321 will affect the upper end of the tube blank 10 and cause it to fail to disconnect safely when the molten metal is installed inside the tube blank 10 and the distance from its upper inner surface is too small. The narrow necks 321 on the first vertical section 323 and the second vertical section 324 on both sides are designed on different horizontal planes to prevent the arcs generated on different narrow necks 321 from affecting each other and causing difficulty in extinguishing the arc when the narrow necks 321 melt simultaneously under abnormally large current.

[0059] Step S205: When the preparation step is the first molding, the second parameter is obtained from the preparation parameters.

[0060] In practice, based on the completed conductor 30, a base 20 is generated through the first molding step, so that the conductor 30 and the base 20 are integrated in the molding step, eliminating the assembly step of the conductor 30 and the base 20 and improving the preparation efficiency.

[0061] Step S206: Based on the second parameter, the base 20 is obtained by injection molding on the conductor 30, and the conductor 30 is inserted into the base 20.

[0062] In one possible embodiment, the second parameter includes a second material parameter and a second process parameter; the base 20 is injection molded based on the conductor 30 according to the second parameter, including: controlling an operating tool to perform the following operations: obtaining a second material according to the second material parameter; determining a first molding die according to the second process parameter; placing the conductor 30 in the first molding die and injecting the second material into the first molding die to obtain a base 20 with the conductor 30 inserted; wherein, please refer to Figure 4 The base 20 includes at least one platform, on which a first through hole and a second through hole are formed. The first connecting part 312 and the second connecting part 313 respectively pass through the first through hole and the second through hole, so that the first electrode 32 and the second electrode 33 respectively exit through the first through hole and the second through hole. At least one mating part 24 is provided on the at least one platform, and the at least one mating part 24 is connected to the cavity wall of the receiving cavity through at least one injection-molded fixing part.

[0063] A first platform 2131 extends from the first end face 211 of the first substrate 21, and a second platform 2132 extends from the first platform 2131; at least one mating part 24 is respectively disposed at a first connection between the first platform 2131 and the first substrate 21, and / or at a second connection between the first platform 2131 and the second platform 2132.

[0064] In specific implementation, corresponding mating parts 24 can be provided on the second step formed between the first substrate 21, the first platform 2131, and the second platform 2132. For example, at least one recess (i.e., mating part 24) can be formed on the side of the first platform 2131. During secondary in-mold molding, the injection molding material fills the recess, thereby making the base 20 and the tube blank 10 integrally connected, and improving the bonding strength between the base 20 and the tube blank 10. The cross-sectional dimensions of the tube blank 10 parallel to the first substrate 21 are equal to the cross-sectional dimensions of the first substrate 21, thereby enabling mold positioning; two fifth end faces 212 (e.g., from the surface of the uppermost platform to the first substrate 21) are formed on the surface of the fifth end face 212 (e.g., from the surface of the uppermost platform to the fifth end face 212 of the first substrate 21) are formed. Figure 7 The through hole (shown) forms the first through hole and the second through hole, and the first connecting portion 312 and the second connecting portion 313 of the conductor 30 are received through the first through hole and the second through hole. Optionally, the mating portion 24 can be a recessed portion or other shapes, such as a through hole that penetrates the platform laterally, a T-slot, or other types of grooves, as long as it can achieve the function described in this embodiment, and is not limited to a single shape.

[0065] The second material is the first injection molding material. Similarly, a corresponding second material number can be configured for each first injection molding material. The main control module determines the second material number, then controls the operating tool to query the second position of the corresponding material based on the second material number, and then obtains the second material from the second position. The main control module controls the operating tool to place the conductor 30 in the preset position of the first molding mold, and then performs injection molding based on the second process parameters, thereby obtaining the base 20 with the conductor 30 inserted.

[0066] The preparation process of conductor 30 will be illustrated below with an example.

[0067] In this example, the completed conductor 30 is placed at a specific position on the first molding die of the base 20, and the conductor 30 and the base 20 are molded into a whole using the Insert Molding process.

[0068] The first molding process is a crucial step in building the basic structure of the entire production process. First, the molded conductor 30 undergoes rigorous pretreatment. Through high-precision surface cleaning and activation processes, impurities such as oxide films and oil stains are removed, ensuring a surface roughness Ra ≤ 0.8 μm to meet the requirements of the Insert Molding process for the metal-plastic interface. The pretreated conductor 30 is then precisely placed into a specific positioning groove in the first molding die of the base 20. This positioning groove is manufactured using precision CNC machining, with dimensional tolerances controlled within ±0.02 mm. Combined with a high-precision positioning pin and guide post system, sub-micron level positioning accuracy is achieved for the conductor 30.

[0069] When using the Insert Molding process, PA66 + 30% glass fiber is selected as the raw material for the base 20. This material possesses both excellent mechanical strength and electrical insulation properties. Its melt flow rate (MFR) must be strictly controlled at 15-20 g / 10 min (275℃ / 2.16 kg). The uniform distribution of glass fiber significantly improves the material's rigidity and creep resistance. During injection molding, the mold temperature is set at 85-95℃, the injection pressure is maintained at 90-130 MPa, and the holding time is 18-22 s. By precisely controlling the parameters, the molten PA66 + 30% glass fiber fully encapsulates the conductor 30 within the mold, forming a robust metal-plastic composite structure after cooling and solidification. Testing shows that the interfacial shear strength of this composite structure must reach ≥30 MPa to ensure a firm bond between the conductor 30 and the base 20, while also meeting electrical insulation performance requirements with an insulation resistance ≥10¹² Ω.

[0070] As can be seen, in this embodiment, the base 20 is prepared by injection molding on the basis of the conductor 30 by the electronic device, so that the conductor 30 and the base 20 are integrally formed, providing support for the subsequent preparation of the target vertical fuse.

[0071] Step S207: When the preparation step is the preparation of the tube embryo 10, the third parameter is obtained from the preparation parameters.

[0072] Step S208: Prepare tube embryo 10 according to the third parameter.

[0073] In one possible embodiment, the third parameter includes a third material parameter and a third process parameter; the preparation of the tube blank 10 according to the third parameter includes: controlling the operating tool to perform the following operations: obtaining a third material according to the third material parameter; determining a second molding die according to the third process parameter; injecting the third material into the second molding die to obtain the tube blank 10; wherein, please refer to Figure 5 The tube body 10 is provided with a receiving cavity, and the first end of the tube body 10 is provided with a first opening 161, which is the entrance of the receiving cavity.

[0074] In specific implementation, the third material parameters include the type of third material required for preparing the tube preform 10 and the corresponding initial specifications of the third material. This material can be glass fiber or other insulating materials. Similarly, different third materials are numbered during production, and the numbers are also different between different initial specifications of the same third material; that is, each specification of the third material has a unique third material number. The main control module determines the third material number, then controls the operating tool to query the corresponding third position of the material based on the third material number, and then obtains the third material from that third position. Based on the second process parameters, the main control module controls the operating tool to inject the material into a preset position within the second molding die, thereby obtaining the tube preform 10.

[0075] The preparation process of conductor 30 will be illustrated below with an example.

[0076] In this example, the tube preform 10 is pre-formed into the required shape using an injection molding process.

[0077] The tube preform 10 is also made of PA66 + 30% glass fiber and manufactured through injection molding. Before injection molding, the raw materials must undergo strict drying treatment to control the moisture content to ≤0.03% to avoid defects such as bubbles and silver streaks during the molding process. The mold design adopts a multi-cavity mold structure, with the number of cavities set according to production efficiency requirements. The surface of the mold cavities is mirror polished to a roughness Ra≤0.2μm, ensuring that the surface finish of the molded tube preform 10 meets the product's appearance and performance requirements.

[0078] During injection molding, segmented temperature control is employed: the barrel temperature is set at 260-270℃ in the front section, 250-260℃ in the middle section, and 240-250℃ in the rear section, while the nozzle temperature is 270-280℃. Injection speed is controlled with a variable speed, starting fast and gradually decreasing. The rapid filling stage uses a speed of 70-90 mm / s, while the holding pressure stage reduces the speed to 15-25 mm / s, ensuring a dense internal structure and eliminating issues such as shrinkage marks and material shortages. Through precise injection molding process control, the tube preform 10 is pre-formed into the designed shape, with dimensional accuracy controlled within ±0.05 mm and wall thickness uniformity deviation ≤0.1 mm, meeting subsequent assembly and performance requirements.

[0079] Step S209: When the preparation step is the second molding, the fourth parameter is obtained from the preparation parameters.

[0080] Step S210: According to the fourth parameter, the tube blank 10 is formed on the base 20 and the conductor 30 to obtain the integrally formed initial fuse 120 (e.g. Figure 7 (As shown).

[0081] In one possible embodiment, the fourth parameter includes a fourth material parameter and a fourth process parameter; the step of forming the tube blank 10 onto the base 20 and the conductor 30 according to the fourth parameter to obtain an integrally formed initial fuse 120 includes: controlling an operating tool to perform the following operations: obtaining a fourth material according to the fourth material parameter; determining a third forming mold according to the fourth process parameter; inserting the base 20 with the conductor 30 inserted into the tube blank 10 through the first opening, and placing the conductor 30, the base 20, and the tube blank 10 in the third forming mold; injecting the fourth material into the third forming mold to form a first substrate 21 at the first opening to seal the first opening, thereby obtaining the initial fuse 120; wherein, the first through hole penetrates the first end face 211 and the second end face of the first substrate 21, and the first end face 211 of the first substrate 21 is integrally formed with the base 20.

[0082] In specific implementation, the fourth material is the second injection molding material. Similarly, a corresponding fourth material number can be configured for each second injection molding material. The main control module determines the fourth material number, then controls the operating tool to query the fourth position of the corresponding material based on the fourth material number, and then obtains the fourth material from the fourth position. The main control module controls the operating tool to place the base 20 with the conductor 30 inserted into the preset position of the third molding mold, and then performs injection molding based on the fourth process parameters to obtain the initial fuse 120.

[0083] The following example illustrates the execution process of the second molding step.

[0084] In this example, the base 20 with the conductor 30 is inserted into the tube blank 10 and placed in a specific position on the third molding mold for the second inner mold forming, so that the tube blank 10 and the base 20 are formed into a whole, and the conductor 30 has been inserted into the tube blank 10.

[0085] Secondary in-mold forming is the core step in achieving the integration of the tube preform 10 and the base 20. First, the prepared base 20 with the conductive element 30 is precisely inserted into the tube preform 10 using an automated robotic arm, with strict control over the insertion perpendicularity deviation to ≤0.5° and the depth tolerance to ±0.1mm. Then, the entire assembly is placed on a specific positioning mechanism in the third forming mold. This mechanism employs a pneumatic clamping and hydraulic assisted positioning system to ensure the positional accuracy of the assembly within the mold.

[0086] The secondary in-mold molding process continues to use PA66+30% glass fiber as the injection molding material, leveraging its excellent interlayer bonding to achieve component integration. The mold temperature is set at 90-100℃, the injection pressure is increased to 110-160MPa, and the holding time is extended to 28-32s. This high temperature and pressure ensures the material fully fills the gaps between the two components, forming a strong chemical bond. After molding, ultrasonic testing and X-ray inspection ensure the absence of internal defects such as pores and gaps. The overall structural tensile strength is ≥40MPa, meeting the product's requirements under complex working conditions, and ensuring the conductor 30 is securely embedded inside the tube preform 10.

[0087] Step S211: When the preparation step is a post-processing step, the fifth parameter is obtained from the preparation parameters.

[0088] Step S212: Perform post-processing on the initial fuse 120 according to the fifth parameter to obtain the target vertical fuse.

[0089] In one possible embodiment, a third through hole 13 is further provided on the first substrate 21 and the base 20; the post-processing includes filling with arc-extinguishing material, and the fifth parameter includes a fifth material parameter and a fifth process parameter; the post-processing of the initial fuse 120 according to the fifth parameter to obtain the target vertical fuse includes: controlling the operating tool to perform the following operations: obtaining arc-extinguishing material according to the fifth material parameter; filling the initial fuse 120 with the arc-extinguishing material from the third through hole 13 according to the fifth process parameter, and sealing the third through hole 13 after filling to obtain the target vertical fuse.

[0090] Specifically, the post-processing also includes a second sealing step, and the fifth parameter includes a second sealing sub-parameter, which includes a second sealing material parameter and a second sealing process parameter.

[0091] After filling is completed, the third through hole 13 is sealed to obtain the target vertical fuse. The process includes: when the preparation step is the second sealing step, obtaining the second sealing material parameters from the preparation parameters; obtaining the second sealing material according to the second sealing material parameters; preparing the second sealing element according to the second sealing material and the second sealing process parameters; inserting the second sealing element into the third through hole 13 to seal the third through hole 13, thereby obtaining the target vertical fuse.

[0092] like Figure 5 As shown, optionally, the third through hole 13 can also be provided on the tube body blank 10, so that arc extinguishing material can be filled through the third through hole 13 on the tube body blank 10.

[0093] In practice, a vibration filling process is used to add the arc-extinguishing material into the tube blank 10 through the third through hole 13, and achieve the required filling density.

[0094] The arc-extinguishing material is filled using a vibration filling process, and refined quartz sand with a particle size of 35-120 mesh is selected, with a silica content of ≥99.9% and a moisture content of ≤0.1%. Before filling, the tube blank 10 is preheated at 40-50℃ to reduce the surface tension of the material and improve the filling effect.

[0095] During the filling process, the tube blank 10 is vertically fixed on an electromagnetic vibration table. The vibration frequency is set to 20-30Hz, and the amplitude is 0.5-1.0mm, ensuring that the arc-extinguishing material is uniformly and densely filled under the combined effects of gravity and vibration. The filling quality is monitored using a weighing method. After filling is complete, a density testing device is used to ensure that the filling density reaches the required level. This ensures that the arc-extinguishing material functions effectively when the fuse disconnects the circuit.

[0096] like Figure 5 As shown, the tube blank 10 is also provided with a constriction portion 14. After the arc-extinguishing material is filled, a second sealing member is pressed from the first end (the end where the first opening is located) of the tube blank 10 towards the second end (the end away from the first opening). (If the third through hole is located on the tube blank 10, the position of the third through hole 13 needs to be covered.) After the first sealing member 40 is pressed into the limiting position above the constriction portion 14 of the tube blank 10, the first sealing member 40 is squeezed to form a constriction, so as to prevent the first sealing member 40 from shifting or falling off during product vibration. Completing the above actions completes the product manufacturing and obtains the vertically mounted compact fuse of the present invention.

[0097] In one possible embodiment, a first step 15 is provided on the outer wall of the first end of the tube blank 10, and the edge of the first substrate 21 is flush with the first step 15; the post-processing also includes encapsulation processing, and the fifth parameter includes a sixth material parameter and a sixth process parameter; the initial fuse 120 is post-processed according to the fifth parameter to obtain a target vertical fuse, including: controlling the operating tool to perform the following operations: obtaining a sixth material according to the sixth material parameter; preparing a first sealing element 40 according to the sixth material and the sixth process parameter, and fitting the first sealing element 40 onto the junction of the tube blank 10 and the base 20 according to the first sealing process parameter, so as to clamp the tube blank 10 and the base 20 together, thereby fixing the tube blank 10 and the base 20 together to obtain the target vertical fuse.

[0098] Specifically, such as Figure 6As shown, the first sealing element 40 has a penetration cavity 41 that penetrates the third and fourth end faces of the first sealing element. The first sealing element is fitted onto the first step 15 through the penetration cavity 41 to assemble with the initial fuse 120, thus obtaining the target vertical fuse. In specific implementation, the first sealing element 40 is pressed upward from the bottom end of the tube blank 10 with the third through hole 13. The first sealing element 40 is made of an elastic metal material (such as beryllium bronze or stainless steel), and its elastic modulus and hardness are precisely adjusted to ensure sealing performance and mechanical strength. The pressing process uses a special hydraulic pressing equipment, with the pressing speed controlled at 5-10 mm / s and the pressure set at 8-12 kN to ensure that the first sealing element 40 is accurately pressed into the limiting position above the constriction portion 14 of the tube blank 10.

[0099] Once the first sealing element 40 reaches the predetermined position, it undergoes a cold extrusion process to reduce its diameter. Radial pressure is applied using a specialized mold to plastically deform it, forming a tight sealing structure. The size and shape of the reduced diameter are strictly controlled to ensure a sealing pressure ≥0.5 MPa between the first sealing element 40 and the tube blank 10, preventing displacement or detachment under vibration or impact conditions. After the first sealing element 40 is pressed in and reduced in diameter, it undergoes electrical performance testing, mechanical performance testing, and appearance quality inspection. Qualified products are the final vertically mounted compact fuse described in this invention.

[0100] In one possible embodiment, the operating tool includes an injection molding tool; the fuse preparation method further includes: in the injection molding process of preparing the tube preform 10, the first molding, the second molding and the post-processing, segmented temperature control and variable speed control are performed according to the corresponding steps; the segmented temperature control refers to adjusting the temperature of multiple parts on the injection molding tool for different steps; the variable speed control refers to adjusting the spraying speed of the nozzle according to the injection molding conditions during the injection molding process.

[0101] In practice, a three-stage temperature control is used for the preparation of the tube preform 10: the temperature of the front section of the barrel is set at 260-270℃, the middle section at 250-260℃, and the rear section at 240-250℃; the nozzle temperature is 270-280℃. For the first molding, the mold temperature is set at 85-95℃. For the second molding, the mold temperature is set at 90-100℃. For post-processing, the pressing speed is controlled at 5-10 mm / s.

[0102] As can be seen, in this embodiment, corresponding temperature control and speed control are performed for different steps to achieve better preparation results and improve the yield of the prepared products.
