Description

Technical Field

[0001] The utility model relates to the technical field of grouting production, in particular to a lightweight grouting molding machine and a grouting production line. Background Art

[0002] Grouting molding is a molding method widely used in ceramic sculptures. It can keep the original shape of the mold more purely, consume less raw materials, and have low cost. Grouting molds are generally divided into two-opening molds and four-opening molds. Whether it is a two-opening mold or a four-opening mold, it needs to be locked in real time during the molding process to ensure product quality. However, the current grouting mold is usually locked by a hydraulic cylinder installed on the outer frame, that is, the mold is locked by external force, and the reaction force generated by the locking will be fed back to the outer frame. In this way, the locking mechanism is large in size and heavy in weight, which leads to the heavy weight of the grouting mold and a large footprint. The requirements for the load-bearing and area of ​​the installation site are high, which is not conducive to promotion and use. In addition, the external hydraulic cylinder needs to output hydraulic pressure each time it is locked, which makes the external hydraulic cylinder have a long service life and is prone to failure.

[0039] Some embodiments of the present invention are described in detail below in conjunction with the accompanying drawings. In the absence of conflict, the features of the following embodiments can be combined with each other.

[0040] First embodiment

[0041] Please refer to Figures 1 to 3 The embodiment of the utility model provides a grouting production line (not shown) for performing grouting molding to obtain a green body. It can lock the grouting mold by mechanical self-locking, has good locking effect, low failure rate, and can achieve lightweight and miniaturization, which is conducive to popularization and use.

[0042] It should be noted that the grouting production line includes a lightweight grouting machine 100 and a blank joining device (not shown). The lightweight grouting machine 100 is used for grouting blanks, and the blank joining device is used to take the blanks out of the lightweight grouting machine 100 to realize blanking operation.

[0043] In this embodiment, the lightweight grouting molding machine 100 is used to produce bathroom appliances, such as basins or toilets, but is not limited to this. In other embodiments, the lightweight grouting molding machine 100 can also be used to produce other ceramic products, and the application scenario of the lightweight grouting molding machine 100 is not specifically limited.

[0044] The lightweight grouting machine 100 includes a first module 110, a second module 120, a mounting seat 130, a crank arm 140 and a telescopic driving member 150. The mounting seat 130 is mounted on the first module 110 and is hinged to the crank arm 140. The crank arm 140 can rotate relative to the mounting seat 130, and the mounting seat 130 can limit the crank arm 140. The telescopic driving member 150 is hinged to the crank arm 140, and the telescopic driving member 150 is used to drive the crank arm 140 to be clamped outside the second module 120, the first module 110 and the mounting seat 130 to achieve mechanical self-locking. Specifically, when the telescopic driving member 150 drives the crank arm 140 to move to a preset position, the crank arm 140 reaches a mechanical self-locking state, and thereafter the telescopic driving member 150 no longer needs to apply a driving force to the crank arm 140, and the first module 110 and the second module 120 can be locked under the action of mechanical self-locking to offset the mold expansion force and ensure the quality of grouting molding. In this way, on the one hand, the telescopic driving component 150 can realize the locking function of the first module 110 and the second module 120 without continuously applying driving force, which can effectively reduce the service life of the telescopic driving component 150, thereby reducing the failure rate of the telescopic driving component 150 and extending the service life of the telescopic driving component 150; on the other hand, the first module 110 and the second module 120 do not need to be externally installed on the outer frame with a hydraulic cylinder (that is, no external force is required to lock the mold), which can effectively achieve lightweight and miniaturization, reduce the load-bearing and area requirements for the installation site, and facilitate popularization and use.

[0045] The first module 110 includes a first mold body 111 and a first positioning plate 112. The first mold body 111 is connected to the first positioning plate 112, and the mounting seat 130 is installed on the first positioning plate 112. The first positioning plate 112 is used to support the first mold body 111 and the mounting seat 130, and the first mold body 111 is used for mud injection. The second module 120 includes a second mold body 121 and a second positioning plate 122. The second mold body 121 is connected to the second positioning plate 122. The second positioning plate 122 is used to support the second mold body 121, and the second mold body 121 is used for mud injection. The second positioning plate 122 is also used to abut against the crank arm 140. Specifically, when the telescopic driving member 150 drives the curved arm 140 to move to a preset position, one end of the curved arm 140 abuts against the first positioning plate 112 through the mounting seat 130, and the other end abuts against the second positioning plate 122 to clamp the first positioning plate 112 and the second positioning plate 122, thereby realizing the locking function of the first mold body 111 and the second mold body 121.

[0046] In this embodiment, the first mold body 111 and the second mold body 121 together form a grouting mold, which is a two-open mold. However, this is not limited to this. In other embodiments, the lightweight grouting molding machine 100 also includes a third mold body and a fourth mold body. The third mold body and the fourth mold body can also be locked by the combined structure of the telescopic drive member 150, the crank arm 140 and the mounting seat 130. At this time, the third mold body and the fourth mold body are arranged in a close fit and are clamped between the first mold body 111 of the first module 110 and the second mold body 121 of the second module 120. The first mold body 111, the third mold body, the fourth mold body and the second mold body 121 together form a grouting mold, which is a four-open mold. When the first mold body 111 and the second mold body 121 are locked, the third mold body and the fourth mold body are clamped between the first mold body 111 and the second mold body 121.

[0047] Further, the telescopic drive member 150 is rotatably mounted on the grouting mold to achieve the supporting effect on the telescopic drive member 150, so that the telescopic drive member 150 can apply force to the curved arm 140 to drive the curved arm 140 to move to the preset position. When the telescopic drive member 150 is extended, the telescopic drive member 150 drives the curved arm 140 to move in one direction; when the telescopic drive member 150 is shortened, the telescopic drive member 150 drives the curved arm 140 to move in another direction. Specifically, since the telescopic drive member 150 is mounted on the grouting mold instead of the outer frame, there is no need for external force to lock the mold, which can effectively achieve lightweight and miniaturization. In addition, the telescopic drive member 150 only needs to drive the curved arm 140 to move to the preset position, and then the first positioning plate 112 and the second positioning plate 122 are locked by mechanical self-locking, and there is no need for the telescopic drive member 150 to continuously apply driving force, so the telescopic drive member 150 requires less power, which further achieves lightweight and miniaturization.

[0048] In this embodiment, the first positioning plate 112 is disposed on the side of the first mold body 111, and the second positioning plate 122 is disposed on the side of the second mold body 121, and the position of the first positioning plate 112 corresponds to the position of the second positioning plate 122. However, this is not limited to this. In other embodiments, the first positioning plate 112 and the second positioning plate 122 are disposed at intervals, and the first mold body 111 and the second mold body 121 are both disposed between the first positioning plate 112 and the second positioning plate 122. The position of the first positioning plate 112 relative to the first mold body 111 and the position of the second positioning plate 122 relative to the second mold body 121 are not specifically limited.

[0049] In this embodiment, the number of the first positioning plate 112, the second positioning plate 122, the telescopic driving member 150, the curved arm 140 and the mounting seat 130 are all two, the two first positioning plates 112 are relatively arranged on both sides of the first mold body 111, the two second positioning plates 122 are relatively arranged on both sides of the second mold body 121, each mounting seat 130 is installed on a first positioning plate 112, each curved arm 140 is simultaneously hinged with a telescopic driving member 150 and a mounting seat 130, and the two curved arms 140 work together to achieve simultaneous locking of both sides of the grouting mold, further improving the locking effect and ensuring product quality. However, it is not limited to this. In other embodiments, the number of the first positioning plate 112, the second positioning plate 122, the telescopic driving member 150, the curved arm 140 and the mounting seat 130 can all be four, or six, and the number of the first positioning plate 112, the second positioning plate 122, the telescopic driving member 150, the curved arm 140 and the mounting seat 130 is not specifically limited.

[0050] The curved arm 140 includes a first clamping section 141, a connecting section 142, and a second clamping section 143 which are connected in sequence. The first clamping section 141 and the second clamping section 143 are relatively arranged at the two ends of the connecting section 142, and the first clamping section 141, the connecting section 142, and the second clamping section 143 together form a U shape. Specifically, the first clamping section 141 is hinged to the mounting seat 130, the first clamping section 141 can rotate relative to the mounting seat 130, the mounting seat 130 can limit the first clamping section 141, the telescopic driving member 150 is hinged to the first clamping section 141, the telescopic driving member 150 can drive the first clamping section 141 to move, and the first clamping section 141 and the second clamping section 143 are clamped together outside the second module 120, the first module 110, and the mounting seat 130 to realize the locking function between the first positioning plate 112 of the first module 110 and the second positioning plate 122 of the second module 120.

[0051] It is worth noting that the force point of the first clamping section 141 and the force point of the second clamping section 143 form a first connecting line, and the force point of the first clamping section 141 and the force point of the mounting seat 130 form a second connecting line. When the curved arm 140 moves to the preset position, the angle between the first connecting line and the second connecting line ranges from 0 to 8 degrees to ensure that the curved arm 140 can achieve mechanical self-locking, thereby locking the first positioning plate 112 and the second positioning plate 122. For ease of understanding, the force point of the first clamping section 141 is represented as a, the force point of the second clamping section 143 is represented as b, the force point of the mounting seat 130 is represented as c, and the angle between the first connecting line and the second connecting line is represented as A.

[0052] Furthermore, when the angle between the first connecting line and the second connecting line is 0, that is, when the first connecting line coincides with the second connecting line, the curved arm 140 reaches the dead point position. At this time, the mechanical self-locking effect is better, and the first positioning plate 112 and the second positioning plate 122 can be further locked, which is stable and reliable.

[0053] Preferably, the lightweight grouting machine 100 further includes a connecting rod 160. One end of the connecting rod 160 is hinged to the first clamping section 141, and the other end is hinged to the mounting seat 130. The connecting rod 160 can rotate relative to the first clamping section 141 and the mounting seat 130 at the same time, and the first clamping section 141 and the mounting seat 130 can both limit the connecting rod 160. When the telescopic drive member 150 drives the crank arm 140 to move to a preset position, the connecting rod 160 rotates to a state perpendicular to the first clamping section 141, so as to realize the mechanical self-locking function.

[0054] Specifically, the force point of the first clamping section 141 is the hinge point between the connecting rod 160 and the first clamping section 141; the force point of the second clamping section 143 is the abutment point between the second clamping section 143 and the second positioning plate 122; and the force point of the mounting seat 130 is the hinge point between the connecting rod 160 and the mounting seat 130. The telescopic driving member 150 is used to drive the crank arm 140 to move to a preset position, so that the force points of the first clamping section 141, the second clamping section 143 and the mounting seat 130 reach the specified position range, so that the angle between the first connecting line and the second connecting line ranges from 0 to 8 degrees. At this time, the effective rotation torque on the connecting rod 160 is close to or even equal to 0, and it will not rotate under the expansion force of the first mold body 111 and the second mold body 121, that is, the mechanical self-locking function is realized, and the first positioning plate 112 and the second positioning plate 122 are locked to prevent the first mold body 111 and the second mold body 121 from relative movement.

[0055] In this embodiment, there are two telescopic drive members 150, one end of the first clamping section 141 is hinged to one telescopic drive member 150, and the other end is hinged to another telescopic drive member 150, and the two telescopic drive members 150 work together to enable the crank arm 140 to quickly move to a preset position, thereby improving the locking efficiency, thereby improving the production efficiency and shortening the production cycle. However, this is not limited to this, and in other embodiments, the number of telescopic drive members 150 can be one or three, and the number and setting position of the telescopic drive members 150 are not specifically limited.

[0056] In this embodiment, the hinge line between the connecting rod 160 and the first clamping section 141 and the hinge line between the telescopic driving member 150 near the mounting seat 130 and the first clamping section 141 are arranged colinearly, so that the telescopic driving member 150 can pull the connecting rod 160 to rotate to a state perpendicular to the first clamping section 141 while pulling the curved arm 140 to move to a preset position through the first clamping section 141, thereby facilitating the realization of a mechanical self-locking function.

[0057] In this embodiment, the telescopic driving member 150 is a cylinder, but is not limited thereto. In other embodiments, the telescopic driving member 150 may be a hydraulic cylinder or an electric cylinder, and the type of the telescopic driving member 150 is not specifically limited.

[0058] The lightweight grouting machine 100 provided by the embodiment of the utility model has a mounting seat 130 mounted on the first module 110 and hinged with the crank arm 140, and a telescopic driving member 150 is hinged with the crank arm 140. The telescopic driving member 150 is used to drive the crank arm 140 to be clamped outside the second module 120, the first module 110 and the mounting seat 130 to achieve mechanical self-locking. Compared with the prior art, the lightweight grouting machine 100 provided by the utility model adopts the crank arm 140 hinged with the mounting seat 130 and the telescopic driving member 150 hinged with the crank arm 140, so that the grouting mold can be locked by mechanical self-locking, with good locking effect and low failure rate, and can be lightweight and miniaturized, which is conducive to popularization and use. The grouting production line has high production efficiency, good product quality and is easy to install.

[0059] Second embodiment

[0060] Please refer to Figures 4 to 6 The embodiment of the utility model provides a lightweight grouting molding machine 100. Compared with the first embodiment, the difference of this embodiment lies in the different mechanical self-locking structure.

[0061] In this embodiment, the lightweight grouting machine 100 no longer includes the connecting rod 160, and the number of the telescopic driving member 150 is only one.

[0062] It is worth noting that the lightweight grouting molding machine 100 also includes a rotary drive member 170 and an eccentric cam 180. The rotary drive member 170 is mounted on the mounting seat 130 and connected to the eccentric cam 180. The rotary drive member 170 is used to drive the eccentric cam 180 to rotate. Specifically, the first clamping section 141 is provided with a matching hole 144, and the eccentric cam 180 is rotatably matched with the matching hole 144. The eccentric cam 180 and the matching hole 144 are both circular, and the eccentric cam 180 can rotate relative to the matching hole 144. The side wall of the matching hole 144 can limit the eccentric cam 180. In the process of the rotary drive member 170 driving the eccentric cam 180 to rotate, the crank arm 140 moves under the cooperation of the eccentric cam 180 and the matching hole 144 until it reaches the preset position.

[0063] Furthermore, the eccentric cam 180 is provided with an axis 181, and the rotary drive member 170 is connected to the axis 181 of the eccentric cam 180 to drive the eccentric cam 180 to rotate. The eccentric cam 180 is relatively provided with a proximal end 182 and a distal end 183, wherein the distance between the proximal end 182 and the axis 181 is the smallest, and the distance between the distal end 183 and the axis 181 is the largest.

[0064] In this embodiment, the force point of the first clamping section 141 is the abutment point between the distal end 183 of the eccentric cam 180 and the first clamping section 141; the force point of the second clamping section 143 is the abutment point between the second clamping section 143 and the second positioning plate 122; the force point of the mounting seat 130 is the connection point between the rotating drive member 170 and the mounting seat 130. Since the axis 181 of the eccentric cam 180 is located in the middle of the output shaft of the rotating drive member 170, the axis 181 of the eccentric cam 180 is represented as the force point of the mounting seat 130. The telescopic drive member 150 and the rotating drive member 170 are used to jointly drive the crank arm 140 to move to a preset position, so that the force points of the first clamping section 141, the second clamping section 143 and the mounting seat 130 reach the specified position range, so that the angle range between the first connecting line and the second connecting line is 0 to 8 degrees. At this time, the effective rotational torque exerted on the eccentric cam 180 is close to or even equal to 0, and it will not rotate under the expansion force of the first mold body 111 and the second mold body 121, that is, the mechanical self-locking function is realized, and the first positioning plate 112 and the second positioning plate 122 are locked to prevent the first mold body 111 and the second mold body 121 from relative movement.

[0065] Preferably, the lightweight grouting machine 100 further includes a bearing 190. The bearing 190 is sleeved outside the eccentric cam 180 and is arranged in the matching hole 144. The bearing 190 can reduce the friction force of the eccentric cam 180 rotating relative to the matching hole 144 to reduce energy consumption, ensure the stability of the rotation of the eccentric cam 180, and thus improve the reliability of the locking function.

[0066] In this embodiment, the rotary drive member 170 is a drive motor, but is not limited thereto. In other embodiments, the rotary drive member 170 may be a pneumatic motor or a hydraulic motor, and the type of the rotary drive member 170 is not specifically limited.
