Description

Technical Field

[0001] The present invention relates to the technical field of electronic component manufacturing, and in particular to a connector plastic part and auxiliary shaping equipment and a preparation method thereof. Background Art

[0002] In the field of electronic equipment manufacturing, connectors are core components for signal transmission. The dimensional accuracy and structural stability of their plastic housings directly affect the electrical performance and service life of the connectors. In the traditional connector plastic part production process, the cooling and shaping process after injection molding is particularly critical. After the plastic part is removed from the mold at high temperature, if it is cooled unevenly or lacks effective constraints, it is very easy to deform due to thermal expansion and contraction of the material, resulting in problems such as shrinkage of the inner wall of the plug end and offset of the opening spacing. This phenomenon is particularly prominent in plastic parts with complex geometric structures (such as U-shaped plug ends): the shrinkage of the inner wall not only reduces the matching accuracy between the plug end and the docking component, but can also cause cracking of the plastic part due to stress concentration, ultimately resulting in a significant reduction in product yield.

[0003] The cooling and shaping solutions currently used in the industry primarily rely on natural cooling or simple air cooling equipment. While natural cooling is cost-effective, it is inefficient and cannot meet the needs of large-scale continuous production. Traditional air cooling equipment, while accelerating heat dissipation, provides insufficient protection against stress and deformation in sensitive areas of the plastic part (such as the inside of the U-shaped connector). Furthermore, existing equipment relies solely on its own weight during the cooling process, remaining flat on the work surface. This makes it impossible to effectively suppress the tendency of the inner wall of the connector opening to shrink toward the center when thermal stress is released.

[0004] In summary, how to build a connector plastic part auxiliary shaping equipment with high efficiency and small error has become a technical bottleneck that needs to be broken through in the connector manufacturing field. Summary of the Invention

[0005] (1) The technical problem to be solved by the present invention is that the cooling process of existing connector plastic parts is inefficient, especially the thin wall of the plug-in end of the connector plastic parts is prone to shrinkage deformation, resulting in poor dimensional stability and low yield of the connector plastic parts.

[0006] (2) Technical solution

[0007] In order to solve the above technical problems, an embodiment of the present invention provides an auxiliary shaping device for connector plastic parts, which is used for auxiliary shaping after melt molding in the production process of connector plastic parts, including a placing table, a fixing device and a cooling device, wherein the placing table can carry the connector plastic parts;

[0008] The fixing device is arranged on the material placement table and includes a shaping block and a base. The base is provided with a bearing surface for bearing the connector plastic part. The shaping block extends outward from the bearing surface to form a guide structure. The outer surface of the shaping block matches the inner wall contour of the plug-in end of the connector plastic part to limit the inward contraction and deformation of the plug-in end of the connector plastic part.

[0009] The cooling device includes an air outlet for directionally blowing cooling airflow toward the plastic part fixing area of ​​the fixing device.

[0010] According to one embodiment of the present invention, the connector plastic part auxiliary molding equipment also includes a control device, which is electrically connected to the cooling device. The control device includes a timer for measuring the connector plastic part auxiliary molding time and a control module for triggering the start and stop of the cooling device. The control device can accurately monitor the time during the cooling process to ensure that the duration of each cooling process meets the set requirements, thereby avoiding uneven cooling effects caused by inaccurate cooling time, and further improving the dimensional accuracy and stability of the connector plastic parts. In addition, the start and stop function of the control module can automatically adjust the operating status of the cooling device according to actual needs, making the cooling process more intelligent and automated, reducing the difficulty of manual operation, and improving production efficiency.

[0011] According to one embodiment of the present invention, a lifting drive mechanism connected to the control device is provided in the bearing surface, the base is provided with a lifting opening passing through the bearing surface, and the shaping block passes through the lifting opening and is connected to the lifting drive mechanism.

[0012] The lifting drive mechanism is connected to the control device and is configured to drive the shaping block to move axially along the lifting opening to adjust the height of the shaping block protruding from the bearing surface. Through this design, the lifting drive mechanism can accurately adjust the shaping block according to the actual situation during the cooling process, ensuring that the connector plastic parts always maintain the correct shape and position during shaping, avoiding deformation or dimensional deviation of the plastic parts due to improper positioning of the shaping blocks. Another function of the lifting mechanism is that when the shaping block generates a certain pressure due to the internal contraction force during the shaping process, the shaping connector plastic parts can be effectively removed from the shaping block through the cooperation of the lifting mechanism and the base bearing surface, effectively avoiding the situation where the connector plastic parts are stuck or difficult to pull out, while ensuring that the shaping blocks can be easily separated to avoid damage to the connector plastic parts, thereby improving the yield rate in the production process.

[0013] According to one embodiment of the present invention, a plurality of groups of fixing devices are provided on the material placement table, and two groups of shaping blocks are provided on the base of each group of fixing devices. The two groups of shaping blocks on the same base can facilitate the operator to pick up and place the connector plastic parts on the base with both hands at the same time, so that the operator can pick up and place the connector plastic parts more conveniently, thereby improving work efficiency; an operating gap is provided between the two groups of shaping blocks, and the operating gaps of all the fixing devices are aligned along a preset direction to form a linearly arranged cooling channel. The operating gap leaves a fault-tolerant space for the operator, avoids mutual interference between adjacent connector plastic parts, and at the same time leaves a heat dissipation space for the shaping and heat dissipation of the connector plastic parts.

[0014] The air outlet is strip-shaped, and the central axis is parallel to the cooling channel, so that the wind force center of the cooling airflow acts on the cooling channel, so that the connector plastic parts on both sides of the cooling channel receive uniform wind force, and at the same time the cooling and shaping efficiency remains consistent, ensuring the uniform quality of the finished connector plastic parts.

[0015] According to one embodiment of the present invention, an independently arranged lifting drive mechanism is provided within the base of each set of fixing devices, and the lifting drive mechanism is connected to the shaping block on the corresponding base; the control device independently controls the lifting and lowering action of each set of lifting drive mechanisms. Since the control device can independently control each set of lifting drive mechanisms, the lifting and lowering timing of each shaping unit can be adjusted in a timely manner according to the actual situation of each shaping unit. When a shaping block is completed, the control device can immediately lower the shaping block to begin cooling, while the other shaping blocks continue to maintain the shaping state. In this way, the shaping and cooling rhythm of each shaping unit are precisely controlled, avoiding product deformation or damage due to asynchronous or delayed operation, thereby further improving the overall yield rate.

[0016] According to one embodiment of the present invention, the connector plastic part auxiliary shaping device further includes:

[0017] A cabinet is arranged on one side of the placing table, and an air outlet of a cooling device is provided on the side wall of the cabinet adjacent to the fixing device; modularizing the cooling function inside the cabinet simplifies the equipment layout and maintenance, and reserves space for the operator's operation; on the other hand, the cooling airflow can act more stably and concentratedly on the fixed area of ​​the connector plastic part, effectively improving the air cooling efficiency and shaping consistency.

[0018] Multiple groups of timing indicator lights, each connected to the timer signal and corresponding to a group of fixtures; the display mode of the timing indicator lights dynamically switches according to the timing phase of the timer to independently display the cooling time progress of the connector plastic parts on the corresponding fixtures. Through intuitive feedback of light color or flashing status, operators can understand the cooling status of each plastic part in real time, facilitate accurate judgment of operation timing, avoid misoperation or missing the optimal demolding window, and further improve operation efficiency and product consistency;

[0019] The control device also includes an operation panel, which is integrated into the side wall of the cabinet. The operation panel is communicatively connected to the control device. The integrated design of the operation panel improves the centralization and convenience of human-computer interaction, making the overall operation logic of the equipment clear and unified, reducing misoperation, and enhancing the controllability of on-site management and the consistency of system operation.

[0020] According to one embodiment of the present invention, a pressure sensor is embedded inside the outer surface of the shaping block, the pressure sensor is electrically connected to the control device, and the detection surface of the pressure sensor is flush with the outer surface of the shaping block, and is used to detect in real time the radial pressure exerted by the plug-in end of the connector plastic part on the shaping block. Through the embedded setting of the pressure sensor, the system can continuously and accurately sense the contact state and deformation pressure between the plastic part and the shaping block during the shaping process, realizing fully automatic monitoring without manual intervention, improving operational efficiency while ensuring the stability of the shaping process.

[0021] The control device is configured as follows:

[0022] receiving real-time pressure data from the pressure sensor;

[0023] When the pressure data is within a preset threshold range and the continuous stability time reaches a set value, a descending instruction is generated and sent to the corresponding driving mechanism to drive the shaping block to move into the bearing surface to a preset position.

[0024] When the pressure data exceeds the preset threshold range, an alarm signal is generated and the action of the driving mechanism is locked.

[0025] According to one embodiment of the present invention, a accommodating and limiting groove for accommodating the protrusion of the end of the connector plastic part is further provided on the top of the calibrating block.

[0026] Another embodiment of the present invention provides a method for preparing a connector plastic part, comprising the following steps:

[0027] a. Injecting molten plastic into the mold to form a connector plastic part having a plug end;

[0028] b. The injection molded connector plastic parts are transferred to the connector plastic parts auxiliary molding equipment as described in any of the above embodiments for cooling and molding, specifically comprising:

[0029] b1. The plug end of the connector plastic part is sleeved on the outside of the guide structure of the shaping block, so that the inner wall of the plug end fits the outer surface of the guide structure;

[0030] b2 start the cooling device, blowing cooling air through the outlet to the fixed area of ​​the plastic part;

[0031] b3. When the cooling time reaches the preset time, remove the connector plastic part from the molding block.

[0032] Another embodiment of the present invention provides a connector plastic part, including a plug-in end interface, and a method for preparing the connector plastic part is the above-mentioned method for preparing the connector plastic part.

[0033] (III) The beneficial effects of the present invention: The directional airflow of the cooling device is concentrated on the fixed area of ​​the plastic part, accelerating heat exchange while ensuring cooling uniformity. At the same time, the precise matching of the guiding structure of the shaping block with the inner wall of the connector plastic end creates a physical limit constraint during the accelerated cooling process, offsetting the internal stress generated by thermal shrinkage of the plastic part and suppressing deformation of the connector end. While accelerating heat exchange, it also avoids shrinkage deformation caused by local stress concentration. The synergistic effect of these two factors significantly improves the dimensional accuracy of the plastic part, production yield, and production efficiency, without relying on complex molds or secondary shaping processes.

DETAILED DESCRIPTION

[0043] In order to more clearly understand the above-mentioned objects, features and advantages of the present invention, the present invention is further described in detail below in conjunction with the accompanying drawings and specific embodiments. In the absence of conflict, the embodiments of the present application and the features in the embodiments can be combined with each other. Obviously, the described embodiments are part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the present invention. Specific embodiments Example

[0044] like Figures 1 to 6 As shown, this embodiment provides a connector plastic part auxiliary shaping device, which is used for the cooling and shaping link after the molten plastic injection molding in the production process of the connector plastic part 1. Its structural composition includes a placing table 2, a fixing device and a cooling device 3.

[0045] The loading platform 2 is used to integrally support the shaping equipment structure and bear the connector plastic part 1. It serves as the foundation for the entire device. Its upper surface is provided with multiple mounting locations for mounting a base 22 of the fixture. Specifically, the base 22 is fixedly embedded in the surface of the loading platform 2. The mounting method can be a slot-fitting, threaded fastening, or guide rail sliding. In this embodiment, a slot-fitting fixing structure is preferably used to ensure that the base 22 remains stable and does not move during operation, facilitating batch deployment and subsequent maintenance and replacement.

[0046] The fixing device is arranged on the material placement table 2 and mainly includes a shaping block 21 and a base 22. The base 22 structure is used to support the shaping block 21 and connect the lifting mechanism. Its upper surface is provided with a bearing surface 221 for supporting the connector plastic part 1. The bearing surface 221 is located above the upper surface of the material placement table 2, that is, the upper end surface of the base 22 is slightly higher than the surface of the material placement table 2, so that the connector plastic part 1 remains exposed after assembly, which is conducive to sufficient contact with the cooling airflow and manual visual inspection. The structural form of the base 22 can be circular, square, or other geometric forms that are suitable for the layout of the shaping block 21. In this embodiment, a rectangular plate structure is selected to facilitate the formation of a continuous parallel arrangement between multiple groups of fixing devices, adapting to the parallel guidance direction of the strip cooling airflow.

[0047] The shaping block 21 extends outward from the bearing surface 221 to form a guide structure. Its outer surface matches the inner wall contour of the connector end of the plastic connector part 1. This fitting and guiding relationship effectively limits the shrinkage deformation of the connector end 1 in the direction of the inner diameter at high temperatures after demolding. The presence of the guide structure not only provides support and positioning for the connector end, but also provides shape restraint during the cooling process. It is particularly suitable for U-shaped connector ends or those with open structures, and can achieve dimensional retention without relying on a closed mold structure.

[0048] like Figure 4 and Figure 6 As shown, preferably, a accommodating limit groove 212 is further provided on the top of the shaping block 21, and the accommodating limit groove 212 is specifically used to accommodate the protrusion at the end of the connector plastic part 1. The design of the accommodating limit groove 212 enables the shaping block 21 to provide precise support and positioning for the protrusion at the end of the connector plastic part 1 during the shaping process. The top edge of the shaping block 21 is precisely designed to accommodate the shape of the protrusion at the end of the connector plastic part 1, ensuring that the protrusion at the end of the connector plastic part 1 is not damaged by excessive pressure or improper contact during the shaping process. The depth and width of this groove are optimized so that it can effectively accommodate the protrusion at the end of the connector plastic part 1 and avoid unnecessary friction or interference during the shaping process.

[0049] Specifically, the retaining groove 212 is typically U-shaped, V-shaped, or other groove-shaped structure that fits the shape of the protrusion at the end of the connector plastic part 1. The shape and size of the retaining groove 212 are adjusted based on the geometric characteristics of the protrusion at the end of the connector plastic part 1 to ensure that the end of the connector plastic part 1 is not subjected to excessive external forces during the molding process, thereby avoiding dimensional deviation or demolding difficulties caused by deformation. The provision of the retaining groove 212 improves the contact stability between the molding block 21 and the connector plastic part 1, ensuring the integrity of the plug end and the plastic part's appearance.

[0050] Furthermore, the contact surface between the retaining groove 212 and the surface of the shaping block 21 has been treated to ensure that the protrusion at the end of the plastic part is firmly seated within the groove and prevent displacement caused by shrinkage after cooling, thus ensuring the stability of the end shape during the shaping process. The design of the retaining groove 212 effectively constrains the shape of the end of the connector plastic part 1, resulting in a more precise shape after cooling, thereby improving the quality consistency and production yield of the final product.

[0051] like Figure 1As shown, the cooling device 3 further includes air outlets 31 for directing cooling airflow toward the plastic part securing area of ​​the fixture. The cooling device 3 is positioned on or above the loading platform 2 and, through one or more sets of air outlets 31, directs the directional airflow to the cooling channels formed outside each set of sizing blocks 21. The arrangement of the sizing blocks 21 and the design of the operating gaps 24 between the fixtures allow the cooling airflow to be concentrated on the key areas of the connector end 1, achieving efficient and uniform heat dissipation.

[0052] Overall, the loading platform 2 provides a mounting base for each component. The base 22 engages with it to form a vertically protruding area. The shaping block 21 is fixed to it to ensure the proper fit of the plug-in end. The cooling device 3 uses the cooling channel as a wind path to evenly distribute the directional airflow to the shaping area, forming a stable closed-loop cooling and shaping process for the multiple components. This structural layout not only ensures the efficiency and controllability of the cooling process, but also effectively improves the dimensional consistency and yield rate of the connector plastic part 1, reducing the need for mold shaping or secondary processing.

[0053] Preferably, the auxiliary shaping device for the connector plastic part 1 further includes a control device 4. The control device 4 is electrically connected to the cooling device 3 and internally includes a timer for measuring the auxiliary shaping time of the connector plastic part 1 and a control module for triggering the start and stop of the cooling device 3. In this embodiment, the control device 4 utilizes digital timing and microprocessor control technology. Its timer module can accurately measure the cooling cycle, while the control module automatically outputs start and stop signals based on pre-set parameters to achieve state adjustment of the cooling device 3. As a result, the entire cooling process is structurally precisely timed, ensuring that each cycle meets design requirements, thereby avoiding uneven heat dissipation caused by cooling time errors and further ensuring the stability of the size and shape of the connector plastic part 1 during the cooling and shaping process.

[0054] like Figure 2 and Figure 3 As shown, the support surface 221 is also provided with a lifting drive mechanism 23 connected to the control device 4. Specifically, the base 22 is provided with a lifting opening 222 that extends through the support surface 221. The shaping block 21 is mechanically linked to the lifting drive mechanism 23 through this opening. Furthermore, the lifting drive mechanism 23 closely cooperates with the support surface 221 of the base 22. During the shaping process, when a certain pressure is generated due to the shrinkage of the plastic part, the mechanism automatically adjusts the height of the shaping block 21, smoothly separating the shaped connector plastic part 1 from the shaping block 21. This prevents the plastic part from getting stuck or damaged during demolding, significantly improving the yield rate during the production process.

[0055] The entire equipment layout features multiple fixtures installed on the loading platform 2. Each fixture's base 22 houses two sets of shaping blocks 21. The structural design allows for compact, non-interfering arrangement of the two sets of shaping blocks 21 on the same base 22, facilitating simultaneous dual-use placement of connector plastic parts 1. The fixtures are aligned with pre-set operating gaps 24, forming a linear cooling channel. This channel design not only provides unimpeded cooling airflow but also leaves ample margin for error, preventing interference between adjacent parts and ensuring uniform heat dissipation during shaping.

[0056] The air outlet 31 of the cooling device 3 is strip-shaped, with its central axis parallel to the cooling channel. This structure ensures that the center of the cooling airflow acts evenly on each fixture within the cooling channel, resulting in a uniform cooling effect on the connector plastic parts 1 on both sides of the channel, further ensuring uniform cooling and consistent finished product quality.

[0057] Through the precise structure and coordination of these components, this embodiment achieves intelligent and automated shaping equipment. Control device 4's combined adjustment of cooling time and lift drive ensures the connector plastic part 1 remains in an ideal state throughout the cooling process. This also simplifies and improves overall equipment operation, significantly improving production efficiency and product yield.

[0058] Each set of fixtures has an independently installed lifting drive mechanism 23 within its base 22, connected to the sizing block 21 on the corresponding base 22. In this embodiment, the lifting drive mechanism 23 is specifically described using a cylinder drive as an example. The cylinder is vertically positioned below the base 22 and connected to the bottom of the sizing block 21 via a piston rod. The cylinder body is fixedly connected to the lower surface of the base 22 by threaded fastening or dowel pin insertion, ensuring guiding stability and repeated movement accuracy during the lifting process.

[0059] In order to further ensure the vertical accuracy of the lifting movement of the shaping block 21, parallel guide columns can be provided on both sides of the cylinder, and rolling or sliding sleeves are provided on the guide columns, so that the shaping block 21 can move stably along the opening axis direction of the bearing surface 221 under the push of the cylinder, avoiding lateral shaking or jamming, and improving the smoothness and position reproducibility of the demoulding action.

[0060] The control device 4 is electrically connected to each set of lifting drive mechanisms 23 and has the ability to independently control each set of lifting drive mechanisms 23. Specifically, the control device 4 receives real-time pressure data from the pressure sensor 211 provided on the outer surface of the shaping block 21 to determine the deformation state and stress release of the plug-in end of the connector plastic part 1 during the shaping process; when the pressure data of a certain set of shaping blocks 21 is stable within the preset threshold range and lasts for a set period of time, the control device 4 will automatically issue a descending command to drive the corresponding cylinder to move the shaping block 21 to the preset position within the bearing surface 221, completing the shaping process and starting the cooling or demolding operation. In this way, each set of fixing devices can make independent judgments and responses based on its current state, ensuring that when the entire equipment is operating at multiple stations, the lifting and lowering rhythms of each shaping unit do not interfere with each other and are precisely coordinated, greatly reducing the risk of plastic part deformation or misoperation due to inconsistent synchronization.

[0061] It is worth noting that, although the present embodiment uses cylinder drive as the preferred structure of the lifting drive mechanism 23, the present invention is not limited to this. The lifting drive mechanism 23 can also be implemented by other mechanical drive methods such as electric push rods, ball screw + stepper motor combination, hydraulic cylinder, etc. The specific structure selection can be flexibly set according to the process space, cost budget and maintenance convenience. In addition, under the condition of sensorless configuration, the control device 4 can also preset a manual operation channel, and the operator manually triggers each group of lifting actions through the control panel, or performs group operations after manual judgment based on the timer data, so as to adapt to the application environment of non-automated production lines or low-cost solutions.

[0062] like Figure 1 As shown, further, in this embodiment, the auxiliary shaping device for the connector plastic part 1 also includes:

[0063] The cabinet 5 is arranged on one side of the material loading platform 2 and is connected to the material loading platform 2 to form an L-shaped integral structure. The arrangement of the cabinet 5 not only makes the equipment structure more compact, but also facilitates the integration and maintenance of the cooling device 3. Specifically, a cooling function module is integrated into the cabinet 5, and the cooling airflow is blown directionally to the plastic part fixing area of ​​the fixing device through the air outlet 31 provided on the side wall of the cabinet 5. This design ensures that the cooling airflow can act more stably and concentratedly on the molding area of ​​the connector plastic part 1, avoiding the dispersion of the cooling airflow, thereby effectively improving the cooling efficiency and molding consistency. There is no gap at the connection between the cabinet 5 and the material loading platform 2, ensuring that the equipment maintains a high degree of stability during use.

[0064] Multiple groups of timing indicator lights 6, each group of timing indicator lights 6 is connected to the signal of the timer, and these indicator lights correspond one to one with the base 22 on the loading platform 2. Specifically, each group of timing indicator lights 6 is connected to the corresponding shaping unit fixture, and the state of the indicator lights can dynamically change according to the progress of the cooling time. The timing indicator lights 6 provide real-time feedback on the cooling state of each shaping unit by changing the light color or flashing frequency. For example, when the cooling time is approaching, the indicator lights will be displayed with a faster flashing frequency to remind the operator that the shaping unit is about to enter the cooling stage or demoulding operation. Since each group of timing indicator lights 6 is relative to their respective shaping unit fixtures, the operator can directly observe and judge the cooling state of each group of shaping units, ensure the timeliness and accuracy of the cooling operation, and avoid product deformation or defectiveness due to delays or misoperations.

[0065] The operation panel 41 is integrated into the side wall of the cabinet 5 and is electrically connected to the control device 4, allowing the operator to fully control the equipment. The operation panel 41 is provided with multiple function buttons and a display screen. Through these control buttons, the operator can independently adjust the cooling time of each shaping unit, start the cooling device 3, control the raising and lowering of the shaping block 21, and perform other operations. The electrical connection between the operation panel 41 and the control device 4 ensures that the operator's settings are reflected in the operating status of the equipment in real time, improving the accuracy and convenience of equipment operation. The location design of the operation panel 41 facilitates quick operation by the operator, reduces unnecessary operating steps, and improves work efficiency.

[0066] In summary, the cabinet 5, the loading platform 2, the timing indicator 6, and the operating panel 41 work together to form the core control system of the equipment. The cabinet 5 provides a reasonable layout space for the cooling device 3 while effectively directing the cooling airflow. The timing indicator 6 cooperates with the shaping device on the loading platform 2 to provide real-time feedback to the operator, ensuring the accurate cooling time of each shaping unit. The operating panel 41 serves as a centralized control interface, ensuring the coordination and smoothness of all equipment operations. The close coordination of these components ensures more uniform and efficient cooling of the connector plastic part 1 during the shaping process, thereby improving product consistency and yield rate.

[0067] like Figure 7 As shown, this embodiment further provides a connector plastic part 1 , which includes two U-shaped plug-in end interfaces 11 , and a U-shaped gap is provided between the two plug-in end interfaces 11 .

[0068] Another embodiment of the present invention provides a method for preparing a connector plastic part 1, comprising the following steps:

[0069] Step 1: Transfer the injection molded connector plastic part 1 to the molding equipment

[0070] First, the operator removes the molded connector component 1 from the injection molding machine and carefully places it on a fixture on the loading platform 2. At this point, a timing device automatically begins to record the cooling process. The operator ensures that the connector component 1's plug-in end fits securely over the guide structure of the sizing block 21, ensuring that the inner wall of the plug-in end is in complete contact with the outer surface of the guide structure of the sizing block 21.

[0071] Step 2: Start the cooling device 3 for cooling

[0072] Once the connector component 1 is stably placed in the calibrating block 21, the operator activates the cooling device 3. Cooling air is directed through multiple air outlets 31 toward the mating end of the connector component 1. This airflow evenly dissipates heat from the connector component 1, ensuring efficient cooling. The operator can monitor the distribution of cooling airflow along both sides of the cooling channel to ensure even coverage of key areas of the connector component 1.

[0073] Step 3: Control the lifting and lowering of the shaping block 21

[0074] As cooling progresses, the lifting drive mechanism 23 begins operating. During the cooling process, when the control device 4 detects the pressure of the connector plastic part 1 in the sizing block 21, the pressure sensor 211 provides real-time data to determine the cooling status of the plastic part. When the pressure data remains within a preset threshold range for a period of time, the control device 4 automatically issues a command to the lifting drive mechanism 23 to slowly move the sizing block 21 downward, freeing the connector plastic part 1 from the sizing block 21. The operator can manually trigger the lifting operation through the operation panel 41, or rely on the automatic control system to precisely control the lifting speed of the sizing block 21.

[0075] Step 4: Demolding and Inspection

[0076] When the cooling time reaches the set duration, the operator can check the status of the timing indicator 6 on the operation panel 41 to confirm that the cooling process has been completed. At this time, the control device 4 sends a descending command, driving the lifting mechanism to move the shaping block 21 downward, smoothly removing the cooled connector plastic part 1 from the shaping block 21. The operator removes the connector plastic part 1 and inspects it for compliance with dimensional and appearance standards. If any deformation or defects are present, the connector plastic part 1 will be returned for reshaping.

[0077] Step 5: Finalize the shape and prepare for the next batch

[0078] After connector part 1 is demolded, the operator transfers it to the next process. The timing device on the equipment automatically resets, and preparations begin to process the next batch of connector parts 1. The operator can continue to operate the equipment or adjust the cooling time according to the production plan to accommodate different types of connector parts 1.

[0079] The above are all preferred embodiments of the present application, and are not intended to limit the scope of protection of the present application. Therefore, any equivalent changes made based on the structure, shape, and principle of the present application should be included in the scope of protection of the present application.
