Description

Technical Field

[0001] The present application relates to the technical field of mode-locking structures, and in particular to a force-increasing mode-locking mechanism. Background Art

[0002] Slip casting forming refers to a method of selecting an appropriate deflocculant to uniformly suspend powdery raw materials in a solution to form a slurry, and then pouring the slurry into a slip casting mold to form a green body according to the mold. It is commonly used to manufacture daily-use ceramics or building ceramics with complex shapes. Slip casting molds are generally divided into two-opening molds and four-opening molds. These molds need to be locked in real time during the forming process to ensure the quality of slip casting production.

[0003] Conventional slip casting molds use hydraulic cylinders installed on the outer frame for locking. The hydraulic cylinders need to maintain the application of external force to lock the frame. With this locking structure, on the one hand, the hydraulic cylinders need to continuously apply force to all sides of the outer frame. Since the hydraulic cylinders need to ensure the accuracy of the applied force, they also need to provide a sufficiently large pressure to maintain the pressure of the oil cylinder, resulting in high manufacturing, replacement, and maintenance costs. After long-term operation, there will be a small amount of internal leakage in the valve parts of the hydraulic system. When the oil cylinder pressure is lower than the set pressure, the hydraulic system needs to be started to re-pressurize, which is unstable and energy-consuming. On the other hand, the frame needs to increase its volume to adapt to the hydraulic cylinder, resulting in a large floor area, heavy weight, and cumbersome assembly and debugging process for the slip casting mold.

[0016] Advantages of the present application:

[0017] 1. An amplifying force die-locking mechanism of the present application, by setting a die-locking base, a die-locking push seat and a die-locking member on a fixed seat. When using the amplifying force die-locking mechanism, a guiding and locking assembly provides a guiding effect on the die-locking push seat, and the die-locking module abuts against one side of the upper die away from the lower die; the die-locking push seat abuts against one side of the lower die away from the upper die. Under the action of a driving member, a push rod drives an internal force locking assembly to move, the die-locking push seat moves towards the die-locking module, and the die-locking push seat drives the lower die to continuously move towards the upper die. When reaching the stroke limit, the lower die abuts against the upper die, and at the same time, a self-locking connecting rod reaches a dead point position to achieve self-locking, so as to ensure that the lower die and the upper die are tightly abutted for grouting. Using the die-locking member to replace the continuous driving of the oil cylinder can ensure the fitting of the upper and lower dies without continuous force application during the grouting process, and can also ensure the normal and stable use of the die-locking member and the driving member under long-term use. At the same time, it can effectively reduce the floor area required by the grouting equipment.

[0018] 2. An amplifying force die-locking mechanism of the present application, by setting a rotatable guiding pressure rod to adapt to the upper die. When the guiding pressure rod rotates, it drives the die-locking module to rotate and then lock or disengage from the upper die, making the locking process of the die-locking member and the upper die fast and accurate, and ensuring the locking efficiency and locking effect.

[0019] 3. An amplifying force die-locking mechanism of the present application, by opening a base installation groove in the die-locking base and setting a push seat installation groove in the die-locking push seat, and using the base installation groove and the push seat installation groove to adaptively install and accommodate the corresponding connecting rod. On the one hand, it can effectively reduce the weight of the die-locking base and the die-locking push seat, and on the other hand, it can further streamline the size of the die-locking member, making the structure of the die-locking mechanism compact and convenient to use.

[0029] In order to make the purpose, technical solutions and advantages of the present application clearer, the present application will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present application and are not used to limit the present application.

[0030] It should be noted that although functional module division is carried out in the device schematic diagram and the logical sequence is shown in the flowchart, in some cases, the steps shown or described can be executed in a different module division in the device or a different sequence in the flowchart. Terms such as "first" and "second" in the specification, claims and the above - mentioned drawings are used to distinguish similar objects and do not necessarily need to describe a specific order or sequence.

[0031] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by those skilled in the technical field to which the present application belongs. The terms used herein are only for the purpose of describing the embodiments of the present application and are not intended to limit the present application.

[0032] Refer to Figure 1 and Figure 2 , the embodiment of the present application provides a force - increasing mold - locking mechanism, including a fixed seat 1, further including a mold - locking base 2 arranged on the fixed seat 1 and a mold - locking push seat 3 slidably connected to the mold - locking base 2. A mold - locking member 4 is connected between the mold - locking base 2 and the mold - locking push seat 3, and a driving member 5 for driving the mold - locking member 4 is arranged on the mold - locking base 2. By setting the mold - locking member 4 to replace the oil cylinder for locking, driven by the driving member 5, the locking member locks the upper mold and the lower mold using a self - locking structure, which can effectively ensure the service life and locking effect of the mold - locking structure.

[0033] The mold clamping base 2, the mold clamping push base 3, and the mold clamping member 4 are arranged on the same side of the fixed base 1. The mold clamping base 2 is installed and fixed through the mold clamping member 4, and the mold clamping push base 3 is connected to the mold clamping base 2 through the mold clamping member 4. Specifically, the mold clamping member 4 includes a guiding and locking assembly 41 connected to the mold clamping base 2 and the mold clamping push base 3, and an internal force locking assembly 42 for driving the mold clamping push base 3. The internal force locking assembly 42 is located in the middle of the mold clamping base 2.

[0034] Referring to Figure 2 and Figure 3 , the guiding and locking assembly 41 includes a guiding pressure rod 411 rotatably connected to the mold clamping push base 3. One end of the guiding pressure rod 411 in the length direction has a mold clamping block 412. The upper mold is provided with a through hole adapted to the mold clamping block 412. The mold clamping block 412 can pass through the through hole in the natural state. When the mold clamping block 412 rotates after being driven by the driving member 5, the mold clamping block 412 rotates 90 degrees, and the mold clamping block 412 abuts against both sides of the through hole, so as to realize the installation and abutment with the upper mold. In order to cooperate with the mold clamping member 4, guiding holes for cooperating with the guiding pressure rod 411 are opened on both sides of the mold clamping base 2 and the mold clamping push base 3. The guiding pressure rod 411 is inserted into the guiding holes and rotatably connected to the guiding holes.

[0035] Referring to Figure 3 and Figure 4, one end of the guiding pressure rod 411 in the length direction is connected to the driving member 5. In this embodiment, this end of the guiding pressure rod 411 passes through the fixed seat 1 and is then connected to the driving member 5, and the guiding pressure rod 411 is rotatably connected to the fixed seat 1. To ensure the assembly accuracy and service life, the guiding pressure rod 411 has a shoulder. A positioning piece 4111 and a wear-resistant pad 4112 are sleeved and installed on one side of the shoulder of the guiding pressure rod 411. One side of the positioning piece 4111 abuts against the shoulder, the other side of the positioning piece 4111 abuts against the wear-resistant pad 4112, and the wear-resistant pad 4112 abuts against the fixed seat 1. By setting the shoulder, the positioning piece 4111 and the wear-resistant pad 4112, when the guiding pressure rod 411 is installed, making the shoulder of the guiding pressure rod 411 abut against the positioning piece 4111 can ensure the assembly accuracy of the guiding pressure rod 411, make the position of the lock module 412 at the end of the guiding pressure rod 411 away from the base accurate, and increase the matching accuracy between the guiding pressure rod 411 and the upper die; the wear-resistant pad 4112 can reduce the damage caused by the rotating guiding pressure rod 411 to the base and thus increase the service life. In addition, to facilitate the pre-tightening force adjustment of the lock module 412, an adjusting nut 413 is provided between the fixed seat 1 and the mold locking base 2. The adjusting nut 413 is rotatably connected to the mold locking base 2, and the guiding pressure rod 411 has a threaded portion threadedly connected to the adjusting nut 413. When the guiding pressure rod 411 rotates to cooperate with the upper die, first rotate the adjusting nut 413 to loosen the adjusting nut 413 so as not to affect the rotation of the guiding pressure rod 411. When the guiding pressure rod 411 rotates and is completed and cooperates with the upper die, rotate the adjusting nut 413 to lock the guiding pressure rod 411. By adjusting the tightness of the adjusting nut 413, the pre-tightening force between the guiding pressure rod 411 and the upper die in the vertical direction can be realized.

[0036] Refer to Figure 5 and Figure 6 , the internal force locking assembly 42 includes a push rod 421 connected to the mold locking push seat 3 and a self-locking link 422 provided on the push rod 421. The mold locking push seat 3 approaches or separates from the lock module 412. Specifically, one end of the push rod 421 in the length direction passes through the mold locking base 2 and is then connected to the driving member 5. The other end of the push rod 421 in the length direction is connected to the self-locking link 422 and passes through the mold locking base 2. To ensure the service life of the push rod 421, a wear-resistant ring is sleeved on the end of the push rod 421 located in the mold locking base 2. To ensure the locking effect, there are two self-locking links 422. The two self-locking links 422 are respectively located on both sides of the push rod 421, and the two self-locking links 422 are symmetrically arranged with respect to the push rod 421. Similarly, there are two guiding locking assemblies 41. The two guiding locking assemblies 41 are respectively arranged on both sides of the two self-locking links 422 away from the push rod 421; and the two guiding locking assemblies 41 are symmetrically arranged with respect to the push rod 421.

[0037] The self-locking link 422 includes a first link 4221, a second link 4222, and a third link 4223 which are hinged to each other. The first link 4221, the second link 4222, and the third link 4223 are connected to corresponding parts through a pin to achieve rotation. One end of the first link 4221, the second link 4222, and the third link 4223 in the length direction is hinged at the same end point, the other end of the first link 4221 is hinged to the clamping mold base 2, the other end of the second link 4222 is hinged to the push rod 421, and the other end of the third link 4223 is hinged to the clamping mold push seat 3. In order to cooperate with the installation of the self-locking link 422, the push rod 421 is provided with a connecting block 4211, and the second links 4222 of the two self-locking links 422 are respectively hinged to the two sides of the connecting block 4211.

[0038] Reference Figure 5 , Figure 6 as well as Figure 7 , similar to the structure of the upper mold, through holes are provided on both sides of the width direction of the lower mold, and the guide pressure rod 411 is provided through the through hole connected to the lower mold, so that the lower mold can slide back and forth along the length direction of the guide pressure rod 411, and the mold locking push seat 3 abuts against the side of the lower mold away from the upper mold, and when the mold locking push seat 3 moves, it can drive the lower mold to move closer to or away from the upper mold. Therefore, by arranging the push rod 421 and the self-locking connecting rod 422 in this way, when the push rod 421 moves driven by the mold locking component 4, the push rod 421 will drive the second connecting rod 4222 to move through the connecting block 4211, and the moving second connecting rod 4222 will drive the first connecting rod 4221 and the third connecting rod 4223 to move, and the moving first connecting rod 4221 and the third connecting rod 4223 will drive the mold locking push seat 3 to move along the guide pressure rod 411 to continuously approach the locking module 412. The grouting upper mold is pressed against the side of the locking module 412 close to the locking mold push seat 3, and the grouting lower mold is pressed against the side of the locking mold push seat 3 close to the locking module 412. Under the action of the power cylinder, the resistance arm L1 is gradually shortened, and the power arm L2 is gradually lengthened to increase the force. When the push rod 421 reaches the stroke limit, the self-locking connecting rod 422 will reach the dead point to form a self-locking structure. The self-locking function of the self-locking connecting rods 422 on both sides can ensure that the locking mold push seat 3 drives the grouting lower mold to always abut against the grouting upper mold to achieve locking for grouting, and during the grouting process, the driving component 5 does not need to keep applying force to the locking component 4.

[0039] To ensure the compact structure of the mold clamping mechanism to adapt to the upper and lower grouting molds, the mold clamping push seat 3 is provided with a push seat installation groove for accommodating the self-locking connecting rod 422. The third connecting rod 4223 is hinged in the push seat installation groove. Similarly, the mold clamping base 2 is provided with a base installation groove 21 for accommodating the self-locking connecting rod 422, and the first connecting rod 4221 is hinged in the base installation groove 21. By providing the base installation groove 21 in the mold clamping base 2 and the push seat installation groove in the mold clamping push seat 3, and using the base installation groove 21 and the push seat installation groove to adaptively install and accommodate the corresponding connecting rods, on the one hand, the weight of the mold clamping base 2 and the mold clamping push seat 3 can be effectively reduced, and on the other hand, the size of the mold clamping component 4 can be further streamlined, so that the upper and lower grouting molds adapted to it can further reduce the volume and the required floor area.

[0040] The driving component 5 includes a first driving member 51 for driving the push rod 421 and a second driving member 52 for driving the guiding pressure rod 411; the first driving member 51 is arranged on the side of the mold clamping base 2 away from the mold clamping push seat 3; the second driving member 52 is arranged on the side of the fixed seat 1 away from the mold clamping base 2. In this embodiment, the first driving member 51 is a power oil cylinder, and the power oil cylinder is installed on the mold clamping base 2 by means of threaded connection to achieve disassembly; the second driving member 52 is a pneumatic actuator, and the pneumatic actuator is installed on the fixed seat 1 by means of threaded connection to achieve disassembly. The power oil cylinder and the pneumatic actuator are both prior arts and can be obtained by purchase, and their structures and principles will not be described in detail.

[0041] The above specifically shows and describes the exemplary embodiments of the present disclosure. It should be understood that the present disclosure is not limited to the detailed structures, setting methods or implementation methods described herein; on the contrary, the present disclosure is intended to cover various modifications and equivalent settings included within the spirit and scope of the appended claims.
