Description

Technical Field

[0001] The invention relates to the field of temperature sensor processing equipment, in particular to a replaceable limiting mold of a temperature sensor. Background Art

[0002] The assembly procedure is particularly important during the processing of temperature sensors. During the assembly process, attention should be paid to the stability of the sensor support structure to avoid errors during operation. This includes ensuring that the electrical connection of the sensor is correct and that the physical installation of the sensor is stable and reliable.

[0003] During the assembly process of the temperature sensor, the contacts of the temperature sensor need to be welded and quality checked, and multiple components need to be installed. These operation steps all require the position of the temperature sensor to be locked to improve the operation accuracy, so the temperature sensor needs to be limited as a whole to provide a stable operating space for the assembly steps.

[0004] In the prior art, a clamp or an independent mold is usually used to limit the position of the temperature sensor. However, the clamp and the independent mold may also experience local shaking or displacement in a small range when limiting the temperature sensor, which may increase the risk of assembly errors and reduce the yield rate of the temperature sensor. Summary of the invention

[0005] The purpose of the present invention is to overcome the shortcomings of the prior art that there is a risk of local position movement when a clamp or an independent mold is used to limit the position of a temperature sensor. A replaceable limiting mold for a temperature sensor is provided. The basic position of the temperature sensor is limited by loading the mold, and a stable pressure is applied to the surface of the temperature sensor by a detachable pressure plate to prevent the temperature sensor from shifting in position under the action of a slight external force.

[0006] The purpose of the present invention is mainly achieved through the following technical solutions:

[0007] A replaceable limiting mold of a temperature sensor comprises a loading mold, a limiting auxiliary mechanism is arranged on the side of the loading mold, the limiting auxiliary mechanism comprises a detachable base, a hydraulic telescopic rod is arranged on the detachable base, a detachable pressing plate is connected to the top of the hydraulic telescopic rod, and the detachable pressing plate is aligned with the loading mold: the lower surface of the detachable pressing plate can be pressed against the upper surface of the loading mold;

[0008] The hydraulic telescopic rod is inserted into the detachable base, and the detachable base is provided with an adsorption type embedded fixing ring capable of adsorbing and fixing the hydraulic telescopic rod.

[0009] At present, when temperature sensors are produced, the limiting measures for temperature sensors in the assembly process usually adopt mold limiting or fixture limiting. However, in the assembly process, multiple different processes are involved, such as contact welding, welding point quality inspection and component assembly. It is not convenient to use these processes to cooperate with the position of independent molds for processing during the assembly process. Therefore, the position of the temperature sensor needs to be moved to carry out processing in each process. During the movement, the use of fixtures or independent molds to limit the temperature sensor is prone to local misalignment problems. Processing in the original relative position will increase the processing error. Excessive processing error will reduce the yield rate.

[0010] In the present invention, the basic position of the temperature sensor is limited by the loading mold, and the temperature sensor is further limited by setting a limiting auxiliary mechanism on the side of the loading mold. The detachable pressure plate applies a stable pressure to the surface of the temperature sensor to prevent the temperature sensor from escaping from the loading mold, thereby ensuring that the processing point of the temperature sensor is accurate enough. On this basis, it can be ensured that the processing error can be controlled within a reasonable range, thereby ensuring the yield rate during the assembly process of the temperature sensor and ensuring the production efficiency of the temperature sensor.

[0011] The detachable base in the present invention can adjust its position by disassembly, so as to facilitate the adaptation of loading molds of different shapes. The hydraulic telescopic rod provides pressure to the detachable pressure plate by hydraulic telescopic means. The detachable pressure plate is used to apply pressure to the surface of the loading mold and the temperature sensor, so as to ensure their limit stability. The hydraulic telescopic rod is inserted into the detachable base and fixed by adsorption through an adsorption-type embedded fixing ring, so that the hydraulic telescopic rod can also be disassembled from the detachable base, which facilitates the adjustment of the position of the detachable base.

[0012] Furthermore, the detachable base includes a seat body, the adsorption type embedded fixing ring is located in the seat body, an elastic connecting piece is provided between the adsorption type embedded fixing ring and the inner wall of the seat body, an air pump is provided on the side of the seat body, a bellows expansion tube is provided in the seat body, the air pump is connected to the adsorption type embedded fixing ring through the bellows expansion tube, and a one-way valve is provided between the bellows expansion tube and the air pump.

[0013] In the present invention, the seat body is used to accommodate the adsorption type embedded fixing ring and the hydraulic telescopic rod. The adsorption type embedded fixing ring is connected to the seat body through an elastic connecting piece. The elastic connecting piece can exert a force on the adsorption type embedded fixing ring to maintain the stability of the adsorption type embedded fixing ring, and can also make the adsorption type embedded fixing ring press against the hydraulic telescopic rod. Negative pressure adsorption is formed between the adsorption type embedded fixing ring and the hydraulic telescopic rod. The negative pressure is formed by connecting the air pump through the corrugated telescopic tube. The one-way valve is used for the travel of the negative pressure environment and avoids the instability of the negative pressure caused by gas reflux.

[0014] The bellows expansion tube can prevent the adsorption-type embedded fixing ring from being separated from the surface of the hydraulic expansion rod due to the pulling of the bellows expansion tube itself through its own elasticity, thereby ensuring the stability of the negative pressure adsorption effect.

[0015] Furthermore, the adsorption-type embedded fixing ring includes an embedded arc plate, which is circumferentially embedded in the side of the hydraulic telescopic rod and fixed to the hydraulic telescopic rod;

[0016] A negative pressure ring cavity is provided in the seat body, and a plurality of suction ports are opened on the negative pressure ring cavity. The outer surface of the negative pressure ring cavity can fit with the embedded arc plate, and the suction ports can abut against the surface of the embedded arc plate;

[0017] The negative pressure annular cavity is communicated with the bellows expansion tube.

[0018] In the present invention, the embedded arc plate is embedded in the side face of the hydraulic telescopic rod, thereby achieving the embedded arc plate and the hydraulic telescopic rod being fixed together. The negative pressure ring cavity is in the seat body, and the fit between the negative pressure ring cavity and the arc recess is achieved by embedding the embedded arc plate in the arc recess, thereby making it more convenient for the negative pressure ring cavity to form negative pressure adsorption on the embedded arc plate. When the negative pressure ring cavity forms negative pressure adsorption on the embedded arc plate, the stability of the hydraulic telescopic rod in the seat body is effectively improved. If it is necessary to increase the negative pressure adsorption force, a suction nozzle can be added at the position of the suction port or the negative pressure in the negative pressure ring cavity can be increased by an air pump, thereby achieving further improvement in the adsorption stability.

[0019] In the present invention, the bellows expansion tube is used to connect the negative pressure ring cavity and the air pump. Due to the expansion and contraction performance of the bellows expansion tube, the negative pressure ring cavity can be locally displaced in the base body under the support of the elastic connecting piece. Since the embedded arc plate needs to be engaged with the negative pressure ring cavity and also needs to be able to escape from the negative pressure ring cavity, the embedded arc plate in the present invention is made of a material with elastic expansion and contraction properties. When the embedded arc plate escapes from the negative pressure ring cavity, even if external force is applied to the negative pressure ring cavity, its deformation will be within the range that can be accommodated by the bellows expansion tube and the elastic connecting piece, thereby avoiding damage to components caused by the plugging and unplugging operations between the hydraulic telescopic rod and the detachable base.

[0020] Furthermore, a limiting cavity is provided on the top surface of the seat body, the limiting cavity is sleeved outside the hydraulic telescopic rod, and a plurality of limiting telescopic blocks are provided in the limiting cavity, which can extend out of the limiting cavity and abut against the hydraulic telescopic rod;

[0021] A plurality of elastic support balls are arranged in the limiting cavity, and the elastic support balls correspond to the limiting telescopic blocks: one elastic support ball corresponds to one limiting telescopic block, one side of the elastic support ball is fixed to the limiting telescopic block, and the other side thereof is fixed to the limiting cavity.

[0022] In the present invention, the limiting cavity is used to accommodate a limiting telescopic block, and the limiting telescopic block can form a side support force for the hydraulic telescopic rod by abutting against the side of the hydraulic telescopic rod, and maintain the side support force through an elastic support ball. The limiting cavity can accommodate the limiting telescopic block, thereby opening the contact position between the hydraulic telescopic rod and the seat body, making it convenient to pull out the hydraulic telescopic rod.

[0023] Furthermore, the hydraulic telescopic rod comprises an outer sleeve, a hydraulic oil chamber and a pressure-bearing oil chamber are arranged in the outer sleeve, a pressure-bearing partition is arranged between the hydraulic oil chamber and the pressure-bearing oil chamber, and the pressure-bearing partition separates the hydraulic oil chamber and the pressure-bearing oil chamber into two independent parts;

[0024] The pressure-bearing partition is provided with a regulating pump for adjusting the distribution of hydraulic oil in the hydraulic oil chamber and the pressure-bearing oil chamber;

[0025] A piston section is arranged in the pressure-bearing oil chamber, and a telescopic section is arranged on the piston section. The piston section can push and pull the telescopic section to extend or retract the outer sleeve.

[0026] In the present invention, the hydraulic oil chamber in the outer sleeve is used to store hydraulic oil, and the regulating pump completes the position adjustment of the piston segment by adjusting the amount of hydraulic oil in the pressure-bearing oil chamber, thereby adjusting the height of the hydraulic telescopic rod, so that the detachable pressure plate can exert pressure on the loading mold, and the telescopic segment telescopes in the outer sleeve following the position of the piston segment.

[0027] Furthermore, a plurality of side grooves are provided on the side of the telescopic section, and the side grooves are evenly distributed circumferentially on the telescopic section.

[0028] The side grooves on the sides of the telescopic section are used to reduce the weight of the telescopic section, and the transmission direction of the external force can also be changed by setting the side grooves, so that the bearing capacity of the telescopic section is enhanced under the same specifications.

[0029] Furthermore, a top end is provided at the top of the hydraulic telescopic rod, and the detachable pressing plate is fixed on the top end.

[0030] The present invention connects the hydraulic telescopic rod and the detachable pressing plate through the top end, thereby increasing the adjustability of the present invention and achieving the ability to adapt to more loading molds.

[0031] Furthermore, the detachable pressure plate includes a limiting shell, a pressure plate force section is provided in the limiting shell, a top end cap is provided on the top of the limiting shell, and the pressure plate force section passes through the limiting shell and is fastened to the top end cap;

[0032] A limiting shaft is provided in the limiting housing, and the limiting shaft can penetrate the pressure plate force application section. A plurality of telescopic latch assemblies are provided on the limiting shaft, and the telescopic latch assemblies can be inserted into the pressure plate force application section.

[0033] A pressing sheet is fixed on the force-applying section of the pressing plate, and the pressing sheet can press against the upper surface of the loading mold.

[0034] In the present invention, the limiting shell is used to accommodate the pressure plate force section and connect the top end head, so that it can support the pressure plate force section under the action of the top end cap, and through the limiting action of the limiting shaft, the pressure plate force section can apply downward pressure to the pressing sheet, and the pressing sheet directly acts on the loading mold to complete the limitation of the loading mold.

[0035] Furthermore, an embedded limiting ring is provided in the pressure plate force section, and the embedded limiting ring includes a ring body, and a limiting hole is provided on the ring body, and the limiting hole is embedded in the pressure plate force section and is interlocked with the pressure plate force section, and a slot is provided on the ring body, and the telescopic latch assembly can be inserted into the slot;

[0036] The telescopic latch assembly comprises a central positioning shaft, on which an elastic support member is provided, one end of the elastic support member is fixed to the central positioning shaft, and the other end of the elastic support member is fixed to a limiting rod, and the limiting rod can be inserted into the slot;

[0037] A reset plate is provided on the side of the limit housing, and a reset cable is provided on the reset plate. One end of the reset cable is fixed to the reset plate, and the other end of the reset cable is fixed to the limit rod: when the reset plate is pulled, the reset cable pulls the limit rod out of the slot.

[0038] In this embodiment, the embedded limit ring can increase the contact area between the ring body and the pressure plate force section by embedding in the pressure plate force section, thereby making the pressure bearing capacity of the pressure plate force section stronger, and the telescopic pin assembly can be inserted into the slot to form a plug-in fixation with the embedded limit ring, thereby making the limiting effect of the limit shaft on the pressure plate force section more stable.

[0039] The reset plate in the present invention can drive the reset cable, thereby pulling the limit rod out of the slot, thereby unlocking the limit shaft from locking the pressure plate force section, thereby freeing the freedom of the pressure plate force section and facilitating adjustment and maintenance of the pressure plate force section.

[0040] Furthermore, a horizontal pressing plate is provided on the top end, and the horizontal pressing plate is aligned with the loading mold: the lower surface of the horizontal pressing plate can be pressed against the upper surface of the loading mold, the horizontal pressing plate avoids the detachable pressing plate, and the axis of the horizontal pressing plate is perpendicular to the axis of the detachable pressing plate.

[0041] In the present invention, the force application point is increased by the horizontal pressure plate, so that a cross pressure is formed between the detachable pressure plate and the horizontal pressure plate to press the loading mold and the temperature sensor downward to limit the position, thereby avoiding problems such as warping of the temperature sensor caused by uneven pressure caused by a single force application point.

[0042] In summary, the present invention has the following beneficial effects compared with the prior art:

[0043] (1) In the present invention, the basic position of the temperature sensor is limited by a loading mold, and the temperature sensor is further limited by setting a limiting auxiliary mechanism on the side of the loading mold. A detachable pressure plate applies a stable pressure to the surface of the temperature sensor to prevent the temperature sensor from falling out of the loading mold, thereby ensuring that the processing point of the temperature sensor is sufficiently accurate. On this basis, it can be ensured that the processing error can be controlled within a reasonable range, thereby ensuring the yield rate of the temperature sensor during the assembly process and ensuring the production efficiency of the temperature sensor.

[0044] (2) The embedded arc plate is embedded in the side surface of the hydraulic telescopic rod, so as to achieve the embedded arc plate and the hydraulic telescopic rod being fixed together. The negative pressure ring cavity is in the seat body, and the fit between the negative pressure ring cavity and the arc recess is achieved by embedding the embedded arc plate in the arc recess, so that it is more convenient for the negative pressure ring cavity to form negative pressure adsorption on the embedded arc plate. When the negative pressure ring cavity forms negative pressure adsorption on the embedded arc plate, the stability of the hydraulic telescopic rod in the seat body is effectively improved. If it is necessary to increase the negative pressure adsorption force, a suction nozzle can be added at the position of the suction port or the negative pressure in the negative pressure ring cavity can be increased by an air pump, so as to further improve the adsorption stability.

[0045] (3) The horizontal pressure plate increases the force application point, so that a cross pressure is formed between the detachable pressure plate and the horizontal pressure plate to limit the downward pressure of the loading mold and the temperature sensor, thereby avoiding problems such as warping of the temperature sensor caused by uneven pressure caused by a single force application point.

DETAILED DESCRIPTION

[0053] In order to make the objectives, technical solutions and advantages of the present invention more clearly understood, the present invention is further described in detail below in conjunction with embodiments and drawings. The exemplary embodiments of the present invention and their description are only used to explain the present invention and are not intended to limit the present invention.

[0054] Example:

[0055] like Figure 1 to Figure 5 As shown, this embodiment relates to a replaceable limiting mold of a temperature sensor, including a loading mold 6, a limiting auxiliary mechanism is provided on the side of the loading mold 6, and the limiting auxiliary mechanism includes a detachable base 1, a hydraulic telescopic rod 2 is provided on the detachable base 1, and a detachable pressing plate 7 is connected to the top of the hydraulic telescopic rod 2, and the detachable pressing plate 7 is aligned with the loading mold 6: the lower surface of the detachable pressing plate 7 can be pressed against the upper surface of the loading mold 6;

[0056] The hydraulic telescopic rod 2 is inserted into the detachable base 1 , and an adsorption-type embedded fixing ring 12 capable of adsorbing and fixing the hydraulic telescopic rod 2 is provided in the detachable base 1 .

[0057] In this embodiment, the workpiece 5 to be processed is a temperature sensor.

[0058] In actual application of this embodiment, the loading mold 6 is first placed at a specified position, the temperature sensor is placed in the loading mold 6, the limiting auxiliary mechanism is arranged on the side of the loading mold 6, and the temperature sensor and the loading mold 6 are pressed down and limited by the limiting auxiliary mechanism to improve the position stability of the loading mold 6 and the temperature sensor.

[0059] When the limiting auxiliary mechanism is arranged, the detachable base 1 is first fixed by fasteners and other connectors, and then the hydraulic telescopic rod 2 is inserted into the detachable base 1 to be fixed and adjusted to a suitable position. At this time, the hydraulic telescopic rod 2 is adsorbed and fixed by the adsorption-type embedded fixing ring 12, thereby improving the stability of the hydraulic telescopic rod 2, and then an external force is applied to the loading mold 6 and the temperature sensor through the detachable pressing plate 7 to press the temperature sensor and the loading mold 6 to form a limit.

[0060] The detachable base 1 includes a base body 11, the adsorption type embedded fixing ring 12 is located in the base body 11, an elastic connecting piece 15 is provided between the adsorption type embedded fixing ring 12 and the inner wall of the base body 11, an air pump 13 is provided on the side of the base body 11, a bellows telescopic tube 124 is provided in the base body 11, the air pump 13 is connected to the adsorption type embedded fixing ring 12 through the bellows telescopic tube 124, and a one-way valve 14 is provided between the bellows telescopic tube 124 and the air pump 13.

[0061] The adsorption type embedded fixing ring 12 includes an embedded arc plate 121, and the embedded arc plate 121 is circumferentially embedded in the side of the hydraulic telescopic rod 2 and fixed to the hydraulic telescopic rod 2;

[0062] The seat body 11 is provided with a negative pressure ring cavity 123, and the negative pressure ring cavity 123 is provided with a plurality of suction ports 122. The outer surface of the negative pressure ring cavity 123 can be fitted with the inner arc plate 121, and the suction ports 122 can abut against the surface of the inner arc plate 121.

[0063] The negative pressure annular cavity 123 is in communication with the bellows expansion tube 124 .

[0064] The embedded arc plate 121 in this embodiment is made of a material with elastic properties, such as rubber or TPU.

[0065] In this embodiment, if it is necessary to fix the hydraulic telescopic rod 2, the embedded arc plate 121 is first embedded and fixed on the hydraulic telescopic rod 2. When the hydraulic telescopic rod 2 is inserted into the seat body 11, the embedded arc plate 121 is embedded in the negative pressure ring cavity 123 of the adsorption type embedded fixing ring 12 by extrusion. At this time, the embedded arc plate 121 is in contact with the adsorption port 122 on the negative pressure ring cavity 123. After starting the air pump 13, a negative pressure environment is formed in the negative pressure ring cavity 123. Since the adsorption port 122 is blocked by the embedded arc plate 121, a one-way valve 14 is provided at the corrugated telescopic tube 124, so only negative pressure can be formed in the negative pressure ring cavity 123, thereby completing the adsorption of the embedded arc plate 121 and achieving the purpose of forming a connection between the hydraulic telescopic rod 2 and the seat body 11.

[0066] In order to increase the connection stability, the adsorption force of the negative pressure environment can be increased by providing an adsorption nozzle at the adsorption port 122 .

[0067] In this embodiment, when the hydraulic telescopic rod 2 is inserted into the seat body 11, the hydraulic telescopic rod 2 will cause the negative pressure ring cavity 123 to shake due to the squeezing of the embedded arc plate 121. However, since the elastic connecting member 15 has the ability of elastic deformation, it can avoid the loosening of the connection position caused by the embedded arc plate 121 squeezing the negative pressure ring cavity 123. The corrugated telescopic tube 124 can effectively ensure the stability of the connection between the air pump 13 and the negative pressure ring cavity 123 through its telescopic ability, avoiding the risk of the negative pressure environment in the negative pressure ring cavity 123 not being formed.

[0068] A limiting cavity 17 is provided on the top surface of the seat body 11. The limiting cavity 17 is sleeved outside the hydraulic telescopic rod 2. A plurality of limiting telescopic blocks 18 are provided in the limiting cavity 17 and can extend out of the limiting cavity 17 and abut against the hydraulic telescopic rod 2.

[0069] A plurality of elastic support balls 16 are provided in the limiting cavity 17 , and the elastic support balls 16 correspond to the limiting telescopic blocks 18 : one elastic support ball 16 corresponds to one limiting telescopic block 18 , one side of the elastic support ball 16 is fixed to the limiting telescopic block 18 , and the other side thereof is fixed to the limiting cavity 17 .

[0070] In this embodiment, when the hydraulic telescopic rod 2 is inserted into the seat body 11, since sufficient clearance is required for insertion and extraction, there is a certain gap between the seat body 11 and the hydraulic telescopic rod 2, which will cause the side support stability of the hydraulic telescopic rod 2 by the seat body 11 to be poor. In this embodiment, a plurality of limiting telescopic blocks 18 are provided, and elastic support balls 16 are used to provide elastic support capability, thereby effectively improving the lateral support capability of the hydraulic telescopic rod 2 in this embodiment and improving the overall stability of this embodiment. The limiting cavity 17 is sufficient to accommodate the elastic support ball 16 and the limiting telescopic block 18, and the limiting cavity 17 can use its own cavity inner wall to provide support force to the elastic support ball 16, so that the elastic force of the elastic support ball 16 can be transmitted to the side of the hydraulic telescopic rod 2 through the limiting telescopic block 18.

[0071] The hydraulic telescopic rod 2 includes an outer sleeve 24, in which a hydraulic oil chamber 28 and a pressure-bearing oil chamber 25 are arranged, and a pressure-bearing partition plate 26 is arranged between the hydraulic oil chamber 28 and the pressure-bearing oil chamber 25, and the pressure-bearing partition plate 26 separates the hydraulic oil chamber 28 and the pressure-bearing oil chamber 25 into two independent parts;

[0072] The pressure-bearing partition plate 26 is provided with a regulating pump 27 for adjusting the distribution of hydraulic oil in the hydraulic oil chamber 28 and the pressure-bearing oil chamber 25;

[0073] A piston section 23 is disposed in the pressure-bearing oil chamber 25 , and a telescopic section 22 is disposed on the piston section 23 . The piston section 23 can push or pull the telescopic section 22 to extend or retract the outer sleeve 24 .

[0074] A plurality of side grooves 21 are disposed on the side of the telescopic section 22 , and the side grooves 21 are evenly distributed circumferentially on the telescopic section 22 .

[0075] The hydraulic oil chamber 28 in the outer sleeve 24 is used to store hydraulic oil. The regulating pump 27 adjusts the position of the piston segment 23 by adjusting the amount of hydraulic oil in the pressure-bearing oil chamber 25, thereby adjusting the height of the hydraulic telescopic rod 2, so that the detachable pressure plate 7 can exert pressure on the loading mold 6, and the telescopic segment 22 can be telescoped in the outer sleeve 24 following the position of the piston segment 23.

[0076] The side grooves 21 on the sides of the telescopic section 22 are used to reduce the weight of the telescopic section 22 , and the force transmission direction of the external force applied to the telescopic section 22 can also be changed by setting the side grooves 21 , so that the bearing capacity of the telescopic section 22 is enhanced under the same specifications.

[0077] A top end 3 is provided at the top of the hydraulic telescopic rod 2 , and the detachable pressing plate 7 is fixed on the top end 3 .

[0078] The detachable pressing plate 7 comprises a limiting shell 710, a pressing plate force section 72 is arranged inside the limiting shell 710, a top end cap 78 is arranged on the top of the limiting shell 710, and the pressing plate force section 72 passes through the limiting shell 710 and is fastened to the top end cap 78;

[0079] The limiting housing 710 is provided with a limiting shaft 77, and the limiting shaft 77 can penetrate the pressure plate force section 72. The limiting shaft 77 is provided with a plurality of telescopic latch assemblies 73, and the telescopic latch assemblies 73 can be inserted into the pressure plate force section 72.

[0080] A pressing sheet 71 is fixed on the pressing plate force applying section 72 , and the pressing sheet 71 can press against the upper surface of the loading mold 6 .

[0081] An embedded limiting ring 79 is provided in the pressure plate force section 72, and the embedded limiting ring 79 includes a ring body 792, and a limiting hole 791 is provided on the ring body 792. The limiting hole 791 is embedded in the pressure plate force section 72 and interlocked with the pressure plate force section 72. The ring body 792 is provided with a slot 793, and the telescopic latch assembly 73 can be inserted into the slot 793;

[0082] The telescopic latch assembly 73 includes a central positioning shaft 731, on which an elastic support member 732 is provided, one end of the elastic support member 732 is fixed to the central positioning shaft 731, and the other end thereof is fixed with a limiting rod 733, and the limiting rod 733 can be inserted into the slot 793;

[0083] A reset plate 74 is provided on the side of the limiting housing 710, and a reset cable 76 is provided on the reset plate 74. One end of the reset cable 76 is fixed to the reset plate 74, and the other end of the reset cable 76 is fixed to the limiting rod 733: when the reset plate 74 is pulled, the reset cable 76 pulls the limiting rod 733 out of the slot 793.

[0084] In this embodiment, the detachable pressing plate 7 is detachable to facilitate adjustment and storage of the detachable pressing plate 7, thereby enhancing the adaptability of this embodiment during application.

[0085] In actual application of this embodiment, the limiting shaft 77 is first inserted into the pressure plate force section 72 and passes through the pressure plate force section 72. At this time, the pressure plate force section 72 and the top end cap 78 can be fixedly connected by fasteners. In order to enhance the stability of the limiting shaft 77, the limiting shaft 77 and the limiting shell 710 can also be fixed by fasteners. At this time, as long as the limiting shell 710 is fixedly connected to the top end head 3, the degree of freedom of the pressure plate force section 72 can be limited. At this time, the pressure plate force section 72 is subjected to external force by the hydraulic telescopic rod 2, and the loading mold 6 can be pressurized by the pressing sheet 71.

[0086] However, due to the existence of the gap, there is a risk of stability in the connection between the limit shaft 77 and the pressure plate force section 72 , so this embodiment enhances the stability of the connection between the limit shaft 77 and the pressure plate force section 72 by providing a telescopic latch assembly 73 .

[0087] The telescopic latch assembly 73 enhances the stability of the connection between the limit shaft 77 and the pressure plate force section 72 by inserting the limit rod 733 into the slot 793. The limit rod 733 is pushed into the slot 793 through the elastic support member 732, and the limit rod 733 is pulled out of the slot 793 by pulling the reset plate 74 with the help of the pulling force of the reset cable 76, so that the limit shaft 77 can be disengaged from the pressure plate force section 72.

[0088] In this embodiment, the limiting housing 710 includes a first housing and a second housing, and the first housing and the second housing can be fastened to form a complete cavity, or can be divided into two independent parts by removing fasteners. Due to the detachability of the limiting housing 710, the limiting shaft 77 and the pressure plate force section 72 in this embodiment can be completely disassembled, thereby achieving the purpose of increasing storage and facilitating maintenance.

[0089] The central positioning shaft 731 in this embodiment is used to provide a support point for the elastic support member 732. The ring body 792 and the limiting hole 791 can increase the force area between the embedded limiting ring 79 and the pressure plate force section 72, thereby ensuring the insertion stability of the limiting rod 733 and the slot 793 and ensuring that the limiting rod 733 can effectively limit the rotational freedom between the limiting shaft 77 and the pressure plate force section 72.

[0090] A horizontal pressing plate 4 is also provided on the top end 3, and the horizontal pressing plate 4 is aligned with the loading mold 6: the lower surface of the horizontal pressing plate 4 can be pressed against the upper surface of the loading mold 6, the horizontal pressing plate 4 avoids the detachable pressing plate 7, and the axis of the horizontal pressing plate 4 is perpendicular to the axis of the detachable pressing plate 7.

[0091] By increasing the force application point through the horizontal pressure plate 4, a cross pressure is formed between the detachable pressure plate 7 and the horizontal pressure plate 4 to press the loading mold 6 and the temperature sensor downward to limit the position, thereby avoiding problems such as warping of the temperature sensor caused by uneven pressure caused by a single force application point.

[0092] The specific implementation methods described above further illustrate the objectives, technical solutions and beneficial effects of the present invention in detail. It should be understood that the above description is only a specific implementation method of the present invention and is not intended to limit the scope of protection of the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
