Description

Technical Field

[0001] This utility model relates to the field of locking device technology, and in particular to a locking device for cold storage panel molds. Background Technology

[0002] Cold storage panels typically use lightweight polyurethane with good thermal insulation properties as the core material, which can effectively reduce heat transfer caused by temperature differences between the inside and outside. They are widely used in freezing and refrigeration systems. Their processing requires extrusion molding through molds. During the molding process, the locking effect of the mold plays a key role in the product quality.

[0003] When traditional cold storage panels are extruded using molds, hydraulic or pneumatic methods are typically used to press the upper mold against the lower mold for locking. During the locking process, both the hydraulic pump and the pneumatic pump need to continuously supply pressure, resulting in energy waste. Furthermore, if the hydraulic or pneumatic system malfunctions and the locking force weakens, the upper and lower molds cannot lock effectively, which can easily cause the extruded material to overflow from the mold, making it impossible to produce cold storage panels normally.

[0004] Therefore, in response to the defects of traditional cold storage panels when extruded by molds, a cold storage panel mold locking device can be designed. Typically, pressure sensing combined with mechanical and hydraulic locking methods can be used to enable normal production even when the hydraulic and pneumatic systems fail, thus facilitating the solution of the aforementioned problems. Utility Model Content

[0005] To overcome the shortcomings of traditional cold storage panels, which require continuous pressure from both hydraulic and air pumps during mold extrusion forming, resulting in energy waste, and the inability to effectively lock the upper and lower molds and produce cold storage panels normally if the hydraulic or air cylinders malfunction, this utility model provides a cold storage panel mold locking device.

[0006] The technical solution is as follows: A cold storage panel mold locking device includes a locking platform, a first locking seat, a locking mechanism, a lower mold, a second locking seat, an upper mold, a third locking seat, and a hydraulic push rod; a lower mold for forming the cold storage panel is provided above the locking platform, and an upper mold for closing the lower mold is provided above the lower mold. The upper mold is fitted onto the outer end of the lower mold. A first locking seat is provided at each corner of the locking platform, and a locking mechanism for locking the lower mold and the upper mold is provided at the center of the upper end of each first locking seat. A second locking seat is provided at each bottom corner of the lower mold, and a third locking seat corresponding to the locking mechanism and the second locking seat is provided at each bottom corner of the upper mold assembly. A hydraulic push rod for connecting the molding equipment is provided at the upper end of the third locking seat.

[0007] Furthermore, the locking mechanism includes a telescopic shaft, a locking block is provided above the telescopic shaft, an electric rotating shaft is provided between the upper end of the telescopic shaft and the locking block, the telescopic shaft and the locking block are connected by the electric rotating shaft, and four sets of locking pins are provided around the outer end of the locking block.

[0008] Furthermore, a pressure ring is fitted onto the surface of the first locking seat, the telescopic shaft is located at the center of the pressure ring, a pressure sensor is installed inside the pressure ring, and a motor slot is opened at the bottom of the first locking seat, with a telescopic motor connected to the telescopic shaft installed inside the motor slot.

[0009] Furthermore, the front end of the locking platform is equipped with a control console, the bottom of the locking platform is equipped with a battery slot, the inside of the battery slot is equipped with a battery pack that is electrically connected to the control console, the bottom of the battery slot is equipped with a battery cover, and one side of the display platform is equipped with a charging interface that is electrically connected to the battery pack.

[0010] Furthermore, a forming groove is provided at the center of the upper end of the lower template, and a corresponding connecting hole is provided at the center of the second locking seat.

[0011] Furthermore, the upper mold has a grouting port through the center, and the bottom center of the third locking seat has a locking port. The side wall of the locking port has four sets of guide pin grooves corresponding to the locking pins, and the inner side of each guide pin groove has an anti-loosening groove.

[0012] Furthermore, the upper end of the telescopic shaft extends through the connecting hole into the interior of the locking port, where the locking block is located.

[0013] The beneficial effects are that the defects existing in the traditional cold storage panel extrusion molding process are addressed by this application through pressure rings and pressure sensors that monitor the locking pressure between the upper and lower molds in real time, providing accurate feedback to the system; the lifting and angle adjustment of the locking block can be flexibly controlled through telescopic shafts, electric rotating shafts, and locking pins, and the anti-loosening locking grooves ensure a stable connection between the upper and lower molds; the hydraulic push rod is responsible for initial pressurization. The combination of these three effectively solves the drawbacks of traditional devices. On the one hand, after the mold is locked, the hydraulic system does not need to continuously supply pressure, relying solely on the mechanical structure to maintain the locking force, avoiding energy waste and reducing operating costs; on the other hand, when the hydraulic or pneumatic system malfunctions, the pressure sensing system triggers an alarm, and the mechanical locking structure can still maintain operation through battery power to prevent raw material spillage and ensure uninterrupted production.

[0020] The present invention will now be described in detail with reference to the accompanying drawings and specific embodiments.

[0021] Example

[0022] like Figures 1-5 As shown, a cold storage panel mold locking device includes a locking platform 1, a first locking seat 2, a locking mechanism 3, a lower mold 4, a second locking seat 5, an upper mold 6, a third locking seat 7, and a hydraulic push rod 8. The locking platform 1 is provided with a lower mold 4 for forming the cold storage panel above it. The lower mold 4 is provided with an upper mold 6 for closing the lower mold 4 above it. The upper mold 6 is sleeved on the outer end of the lower mold 4. The corners of the locking platform 1 are provided with first locking seats 2. The upper center of the first locking seats 2 is provided with a locking mechanism 3 for locking the lower mold 4 and the upper mold 6. The bottom corners of the lower mold 4 are provided with second locking seats 5. The bottom corners of the upper mold are provided with third locking seats 7 corresponding to the locking mechanism 3 and the second locking seats 5. The upper end of the third locking seat 7 is provided with a hydraulic push rod 8 connected to the molding equipment.

[0023] The locking mechanism 3 includes a telescopic shaft 9, a locking block 11 above the telescopic shaft 9, and an electric rotating shaft 10 between the upper end of the telescopic shaft 9 and the locking block 11. The telescopic shaft 9 and the locking block 11 are connected by the electric rotating shaft 10. Four sets of locking pins 12 are arranged around the outer end of the locking block 11. The telescopic shaft 9 can flexibly control the lifting and lowering of the locking block 11. The electric rotating shaft 10 enables the locking block 11 to rotate and adjust its angle. With the help of the four sets of locking pins 12, a stable mechanical locking of the upper mold 6 and the lower mold 4 is achieved.

[0024] A pressure ring 13 is fitted onto the surface of the first locking seat 2. The telescopic shaft 9 is located at the center of the pressure ring 13. A pressure sensor (model PK7520) is installed inside the pressure ring 13. A motor slot 16 is opened at the bottom of the first locking seat 2. A telescopic motor 17 (model ZWPD012012) connected to the telescopic shaft 9 is installed inside the motor slot 16. Through the setting of the pressure ring 13 and the pressure sensor, the locking pressure between the upper mold 6 and the lower mold 4 can be monitored in real time, providing accurate pressure data feedback for the system. The telescopic motor 17 is installed in the motor slot 16, which facilitates the drive control of the telescopic shaft 9.

[0025] The locking platform 1 has a control console 14 at its front end and a battery slot 18 at its bottom. The battery slot 18 contains a battery pack 19 that is electrically connected to the control console 14. A battery cover 20 is provided below the battery slot 18. A charging interface 15 that is electrically connected to the battery pack 19 is provided on one side of the display platform. The control console 14 allows operators to easily set parameters, monitor operation, and control the entire device. The battery pack 19 provides backup power for the device, ensuring normal operation of the device in the event of an external power failure.

[0026] A forming groove 22 is provided at the center of the upper end of the lower template, and a corresponding connecting hole 21 is provided at the center of the second locking seat 5. The connecting hole 21 on the second locking seat 5 cooperates with the telescopic shaft 9 in the locking mechanism 3, so that the telescopic shaft 9 can pass smoothly through and extend into the locking port 24 of the upper mold 6, thereby realizing the effective connection and locking of the upper mold 6 and the lower mold 4.

[0027] The upper mold 6 has a grouting port 23 through the center, and the bottom center of the third locking seat 7 has a locking port 24. The side wall of the locking port 24 has four sets of guide pin grooves 25 corresponding to the locking pins 12. The inner side of each guide pin groove 25 has an anti-disengagement groove 26. The grouting port 23 facilitates the injection of raw materials into the forming groove 22 of the lower mold 4 during the mold forming process. The guide pin grooves 25 provide guidance for the insertion of the locking pins 12, so that the locking pins 12 can be accurately and quickly inserted into the locking position. The anti-disengagement grooves 26 prevent the locking pins 12 from accidentally disengaging during the locking process.

[0028] The upper end of the telescopic shaft 9 extends through the connecting hole 21 into the interior of the locking port 24. The locking block 11 is located inside the locking port 24. Through the cooperation of the locking pin 12 and the anti-loosening groove 26, the upper mold 6 and the lower mold 4 are firmly locked, ensuring that the connection between the upper mold 6 and the lower mold 4 is stable and reliable during the mold extrusion molding process, and effectively preventing the mold from loosening.

[0029] During operation, the worker first places the lower mold 4 above the locking platform 1, ensuring that the second locking seat 5 at the bottom corner of the lower mold 4 corresponds to the first locking seat 2 at the corner of the locking platform 1. Then, the upper mold 6 is fitted onto the outer end of the lower mold 4, so that the third locking seat 7 at the bottom corner of the upper mold 6 corresponds to the second locking seat 5 and the locking mechanism 3. Next, the hydraulic push rod 8 connected to the pressing equipment pushes the upper mold 6 down. When the upper mold 6 is pressed down until the third locking seat 7 contacts the second locking seat 5, the locking block 11 pushes into the locking port 24. At this time, the pressure of the second locking seat 5 on the pressure ring 13 changes. The control console 14 drives the electric rotating shaft 10 to rotate the locking block 11. The rotation of the locking block 11 causes the four sets of locking pins 12 to engage in the anti-loosening groove 26. Then, the control console 14 starts the motor to drive the telescopic shaft 9 to retract, causing the locking pins 12 to be further fixed in the anti-loosening groove 26.

[0030] Its working principle is as follows: when the hydraulic push rod 8 pushes the upper mold 6 down, the hydraulic system provides the initial locking force, while the pressure ring 13 and the pressure sensor monitor the pressure change between the upper mold 6 and the lower mold 4 in real time. When the pressure reaches the set threshold, the control console 14 triggers the electric rotating shaft 10 and the telescopic shaft 9 to move: the electric rotating shaft 10 drives the locking block 11 to rotate, so that the locking pin 12 slides into the anti-disengagement groove 26 along the guide pin groove 25, forming a mechanical locking structure; the retraction of the telescopic shaft 9 strengthens the tightness of the locking pin 12 and the anti-disengagement groove 26 through the tension. At this time, the mechanical locking force replaces the hydraulic continuous pressure supply. The battery pack 19 serves as a backup power source. In the event of external power supply or hydraulic system failure, it can drive the telescopic shaft 9 and the electric rotating shaft 10 to maintain the mechanical locking state and prevent material overflow. The design of the molding groove 22 and the injection port 23 ensures that the material is filled evenly.

[0031] Its beneficial effects are significant. The pressure ring 13 and pressure sensor monitor the locking pressure between the upper mold 6 and the lower mold 4 in real time, providing accurate feedback to the system. The telescopic shaft 9, electric rotating shaft 10 and locking pin 12 can flexibly control the lifting and angle adjustment of the locking block 11, and together with the anti-loosening groove 26, a stable connection between the upper mold 6 and the lower mold 4 can be achieved. The hydraulic push rod 8 is responsible for initial pressurization. The combination of the three effectively solves the drawbacks of traditional devices. On the one hand, after the mold is locked, the hydraulic system does not need to continuously supply pressure, and only the mechanical structure maintains the locking force, avoiding energy waste and reducing operating costs. On the other hand, when the hydraulic or pneumatic system fails, the pressure sensing system triggers an alarm, and the mechanical locking structure can still be powered by the battery pack 19 to maintain operation, preventing raw material spillage and ensuring uninterrupted production.
