DETAILED DESCRIPTION

[0018] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only 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 creative work are within the scope of protection of the present invention.

[0019] Example 1

[0020] like Figures 1 to 7 As shown, an embodiment of the present invention is a socket shell injection cooling device, including an injection mold 100, a refrigeration box 200, and a circulating water tank 300, including a moving mechanism 400 for driving the injection mold 100 to cool and lift, and multiple sets of sliding mechanisms 500 are arranged at the upper end of the interior of the refrigeration box 200; the sliding mechanism 500 includes a ball 501 embedded in the inner wall of the refrigeration box 200 and rolling, a ball groove 502 opened on the side wall of the refrigeration box 200, a positioning spring 503 fixed to the side wall of the ball groove 502, and a position sensor for detecting the inclination of the multiple sets of ball 501; the position sensor is connected to a control module through a signal, and the sliding mechanism 500 monitors its own state through the control module and issues a prompt to adjust the angle of the injection mold 100.

[0021] Specifically, after injection molding, the socket shell needs to be quickly cooled to solidify the plastic material to ensure the dimensional stability and surface quality of the product. The refrigeration box 200 has a refrigeration system inside to provide a continuous low-temperature environment inside the refrigeration box 200, and the circulating water tank 300 stores cooling medium.

[0022] Furthermore, when the injection molding of the socket shell is completed, the moving mechanism 400 starts to drive the injection mold 100 to slowly descend into the refrigeration box 200 for cooling. During this process, when the moving mechanism 400 drives the injection mold 100 to enter the refrigeration box 200, it first contacts the ball 501 on the inner wall of the refrigeration box 200. Through the ball 501, the injection mold 100 can enter the refrigeration box 200 for cooling even when the position with the refrigeration box 200 is not very precise. When the injection mold 100 completely enters the refrigeration box 200, the inclination of multiple groups of balls 501 is detected by the position sensor. The position sensor sends the detected inclination data of the balls 501 to the control module. After the control module analyzes the data, if it is analyzed that the inclination of the injection mold 100 affects the cooling plasticity of the socket shell, the staff will be reminded to adjust the angle of the injection mold 100 to avoid the inclination of the injection mold 100 affecting the product quality of the socket shell after cooling, thereby effectively improving the product quality of the socket shell after cooling.

[0023] Furthermore, why not fix the position of the steel ball at the beginning, so that the injection mold 100 can be positioned and prevented from tilting? Because if the position of the steel ball is fixed, the injection mold 100 may need to be aligned very accurately when entering the cooling box, otherwise friction or jamming will occur, and the injection mold 100 will expand and contract with the cooling box when cooling. Not fixing the steel ball can make the steel ball adapt to the thermal expansion and contraction of the injection mold 100.

[0024] like Figures 1 to 3 As shown, the sliding mechanism 500 further includes a warning light 504 installed on the outside of the refrigeration box 200. When the control module analyzes that the tilt of the injection mold 100 affects the cooling plasticity of the socket shell, the warning light 504 will be controlled to light up. By installing the warning light 504 on the outside of the refrigeration box 200, it is convenient for the staff to quickly observe the state of the injection mold 100 from the outside, reducing the frequency and complexity of manual inspection and improving the cooling production efficiency of the socket shell.

[0025] Please pay attention to Figures 1 to 5 As shown, it also includes a quick cooling mechanism 600 arranged inside the refrigeration box 200 for accelerating the cooling of the injection mold 100; the side wall of the refrigeration box 200 is provided with a long groove 201; the quick cooling mechanism 600 includes a cold plate 601 placed in the refrigeration box 200, a hollow groove 602 opened on the cold plate 601, a limit rod 603 fixed to the back of the cold plate 601, a push spring 604 fixed to the limit rod 603, a circulating heat pipe 605 placed inside the hollow groove 602, and a heat dissipation fin 606 installed in the hollow groove 602.

[0026] Specifically, the design of the limit rod 603 and the push spring 604 ensures that the cold plate 601 is in a stable position in the refrigeration box 200, while allowing it to move within a certain range to adapt to the lifting and lowering of the mold. The two ends of the circulating heat pipe 605 are inserted into the circulating water tank 300. The heat dissipation fins 606 are used to increase the heat exchange area and improve the cooling efficiency. When the injection mold 100 is placed in the refrigeration box 200, the cooling medium in the circulating water tank 300 is circulated by the pump so that the cooling medium circulates in the circulating heat pipe 605, takes away the heat of the injection mold 100 and transfers it to the circulating water tank 300 for cooling.

[0027] Furthermore, when the moving mechanism 400 is started to drive the injection mold 100 to slowly descend into the refrigeration box 200 for cooling, the injection mold 100 conflicts with the cold plate 601 when it descends, thereby driving the limit rod 603 to move in the long groove 201, thereby causing the push spring 604 to contract. When the injection mold 100 completely enters the refrigeration box 200, the cold plate 601 is driven to contact the injection mold 100 through the tensioning force of the push spring 604, thereby making the rapid cooling mechanism 600 closer to the injection mold 100, which is beneficial to accelerate the cooling speed of the socket shell in the injection mold 100, and can also adapt to different injection molds 100.

[0028] Please pay attention to Figures 1 to 5 As shown, both ends of the circulating heat conducting pipe 605 are bellows. Specifically, the bellows are connected to accommodate the movement of the cold plate 601.

[0029] Please pay attention to Figures 1 to 3 As shown, the moving mechanism 400 includes an electric push rod 401 fixed to the bottom of the refrigeration box 200 , a connecting plate 402 fixed to the output end of the electric push rod 401 , and a replacement component 403 for connecting the connecting plate 402 and the injection mold 100 .

[0030] Furthermore, after the injection molding of the socket shell is completed, the output end of the electric push rod 401 descends to drive the connecting plate 402 and the injection mold 100 to descend, and then drives the socket shell placed in the injection mold 100 into the refrigeration box 200. The injection mold 100 can be quickly driven into the cooling box through the moving mechanism 400, so that the socket shell can be quickly cooled.

[0031] Please pay attention to Figures 1 to 7 As shown, the connecting plate 402 is provided with a drawing groove 402a and a fixing groove 402b; the convenient replacement component 403 includes a connecting rod 403a fixedly connected to the bottom of the injection mold 100, a retaining ring 403b sleeved on the connecting rod 403a, a bottom block 403c fixedly connected to the bottom of the connecting rod 403a, a pull rod 403d placed in the drawing groove 402a, a side block 403e sleeved on the pull rod 403d, and a tension spring 403f sleeved on the pull rod 403d.

[0032] Please pay attention to Figures 1 to 7 As shown, one end of the pull rod 403d is fixed in the groove 402b, and the other end of the pull rod 403d passes through the groove 402a, and one end of the pull rod 403d is provided with an inclined clamping surface; the side block 403e is fixedly connected to the connecting plate 402; the two ends of the tension spring 403f are respectively fixedly connected to the side block 403e and one end of the pull rod 403d, and the bottom of the bottom block 403c is an arc surface.

[0033] Furthermore, when the injection mold 100 of the socket housing needs to be replaced, the pull rod 403d is pulled by hand or a tool to separate the inclined clamping surface on the pull rod 403d from the clamping ring 403b. At this time, the connection between the injection mold 100 and the connecting plate 402 is released. After the pull rod 403d is separated from the clamping ring 403b, the injection mold 100 can be easily removed from the connecting plate 402, and then the connecting rod 403a on the new injection mold 100 is inserted into the fixed groove 402b. In this process, the bottom block 403c first enters the fixed groove 402b, The pull rod 403d is pushed into the pull groove 402a through the arc-shaped bottom of the bottom block 403c. At this time, the tension spring 403f contracts. When the pull rod 403d is aligned with the gap between the bottom block 403c and the retaining ring 403b, the tension spring 403f resets and drives the pull rod 403d to be clamped into the gap between the bottom block 403c and the retaining ring 403b. At this time, the injection mold 100 and the connecting plate 402 are firmly connected. The replacement component 403 is helpful to adapt to injection molds 100 of different specifications and models to meet the production requirements of different socket shells.

[0034] Example 2

[0035] like Figures 1 to 8 Please pay attention to Figure 8 As shown, the control module includes: the control module includes: a state detection unit, the state detection unit is used to collect the inclination of multiple groups of balls 501 detected by the position sensor; a vibration detection unit, the vibration detection unit is used to detect the vibration size data when the injection mold 100 descends; a data processing unit, the state detection unit is used to collect the inclination of multiple groups of balls 501 detected by the position sensor and transmit it to the data processing unit, the vibration detection unit is used to detect the vibration size data when the injection mold 100 descends and transmit it to the data processing unit, the data processing unit performs weighted summation based on the inclination of multiple groups of balls 501 and the vibration size data when the injection mold 100 descends to comprehensively determine whether to issue a prompt to adjust the angle of the injection mold 100; a control unit, the control unit controls the opening of the prompt light 504 according to the analysis result of the data processing unit.

[0036] Specifically, the initial positions of the multiple groups of balls 501 are vertically and horizontally aligned before the injection mold 100 enters the cooling box. After the injection mold 100 enters the cooling box, the positions of the multiple groups of balls 501 are the final positions. The inclination of the multiple groups of balls 501 is obtained by comparing the position difference between the final position and the initial position of the upper and lower groups of balls 501. The greater the inclination of the multiple groups of balls 501, the greater the possibility that the injection mold 100 is tilted.

[0037] Specifically, the automatic adjustment of the control module is mainly related to two factors: one is the inclination of the multiple groups of balls 501 detected by the position sensor, and the other is the vibration size data when the injection mold 100 descends. The data processing unit performs weighted summation based on the inclination of the multiple groups of balls 501 and the vibration size data when the injection mold 100 descends to determine whether to turn on the prompt light 504 to remind the staff to adjust the position of the injection mold 100 to improve the product quality of the socket shell after injection cooling.

[0038] In order to combine the inclination of multiple sets of balls 501 and the vibration magnitude data when the injection mold 100 is lowered by weighted summation, we have marked them as and V, and introduce two weights and to indicate their importance in the weighted sum.

[0039] The weighted sum expression can be = × + ×V in: It is expressed as the inclination of multiple groups of balls 501.

[0040] V represents the vibration magnitude data when the injection mold 100 descends.

[0041] is the weight of the inclination of the plurality of groups of balls 501 .

[0042] is the weight of the vibration magnitude data when the injection mold 100 descends.

[0043] Among them, the result of weighted summation This reflects the degree of tilt of the injection mold 100 . A threshold value T can be set to determine when to turn on the reminder light 504 to remind the staff to adjust the position of the injection mold 100 to improve the product quality of the socket housing after injection molding and cooling.

[0044] Where: T is a preset threshold value, which is set according to the actual situation. When the threshold value T is exceeded, it indicates that the prompt light 504 needs to be turned on to remind the staff to adjust the position of the injection mold 100, otherwise it is not necessary.

[0045] Pass indicator light 504 = ; In practical applications, the weight and The choice of should be based on the specific application scenario and requirements to ensure that they can accurately reflect the relative importance in the scenario. At the same time, the sum of these two weights should usually be equal to 1 (or 100%, if expressed as a percentage) to indicate that they together constitute the total weight of the entire weighted sum.

[0046] The state detection unit is used to collect the inclination of the multiple groups of balls 501 detected by the position sensor and transmit it to the data processing unit. The vibration detection unit transmits the vibration size data detected when the injection mold 100 is lowered to the data processing unit. The data processing unit substitutes the relevant information into = × + ×V, the data processing unit is compared , T determines when to control the turning on of the prompt light 504, and turns on the prompt light 504 to remind the staff to adjust the position of the injection mold 100 to improve the product quality of the socket housing after injection molding and cooling. >T, at this time, the control unit controls the prompt light 504 to turn on, and then the staff adjusts the position of the injection mold 100. At T, at this time, it indicates that the injection mold 100 is tilted at a low degree, that is, the degree to which the cooling effect of the socket housing is poor is low. The control unit does not need to turn on the prompt light 504, and the staff does not need to adjust the position of the injection mold 100.

[0047] The above formulas are all dimensionless and numerical calculations. The formula is a formula for the most recent real situation obtained by collecting a large amount of data and performing software simulation. The preset parameters in the formula are set by technicians in this field according to actual conditions.
