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, a large footprint, and inconvenient installation. 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 prone to failure.

[0048] 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.

[0049] First embodiment

[0050] Please refer to Figures 1 to 4 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 through mechanical self-locking, does not require continuous application of driving force, has a low failure rate, and has a compact and light overall structure, which is easy to install.

[0051] 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.

[0052] 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.

[0053] The lightweight grouting machine 100 includes a first module 110, a second module 120, an eccentric cam mechanism 130, a tie rod 140, and a locking mechanism 150. The eccentric cam mechanism 130 is mounted on the first module 110 and connected to the tie rod 140. The first module 110 can carry and position the eccentric cam mechanism 130. The locking mechanism 150 is mounted on the second module 120 and cooperates with the tie rod 140. The second module 120 can carry and position the locking mechanism 150. The eccentric cam mechanism 130 is used to drive the locking mechanism 150 to approach the first module 110 through the pull rod 140, so that the first module 110 and the second module 120 are close to each other. When the eccentric cam mechanism 130 drives the pull rod 140 to move to the preset position, the pull rod 140 reaches a mechanical self-locking state. After that, the eccentric cam mechanism 130 does not need to apply a driving force to the pull rod 140. 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 eccentric cam mechanism 130 and the locking mechanism 150 do not need to continuously apply a driving force to realize the locking function of the first module 110 and the second module 120, which can effectively reduce the failure rate and extend the service life; on the other hand, the first module 110 and the second module 120 do not need to be externally connected to the hydraulic cylinder installed on the outer frame (that is, no external force is required to lock the mold), which can effectively achieve lightweight and miniaturization. The overall structure is compact and light, and easy to install.

[0054] The first mold assembly 110 includes a first mold body 111 and a first mounting plate 112. The first mold body 111 is connected to the first mounting plate 112, the eccentric cam mechanism 130 is mounted on the first mounting plate 112, the first mounting plate 112 is used to carry the first mold body 111 and the eccentric cam mechanism 130, and the first mold body 111 is used for mud injection. The second mold assembly 120 includes a second mold body 121 and a second mounting plate 122, the second mold body 121 is connected to the second mounting plate 122, the locking mechanism 150 is mounted on the second mounting plate 122, the second mounting plate 122 is used to carry the second mold body 121 and the locking mechanism 150, and the second mold body 121 is used for mud injection. Specifically, after the locking mechanism 150 and the pull rod 140 are coordinated, the eccentric cam mechanism 130 drives the pull rod 140 to move to a preset position, one end of the pull rod 140 applies a pulling force to the first mounting plate 112 through the eccentric cam mechanism 130, and the other end applies a pulling force to the second mounting plate 122 through the locking mechanism 150, so as to clamp the first mounting plate 112 and the second mounting plate 122, thereby realizing the locking function of the first mold body 111 and the second mold body 121.

[0055] 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, and the third mold body and the fourth mold body can also be locked by the combined structure of the eccentric cam mechanism 130, the pull rod 140 and the locking mechanism 150. 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 mold group 110 and the second mold body 121 of the second mold group 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.

[0056] In this embodiment, the first mounting plate 112 is disposed on the side of the first mold body 111, and the second mounting plate 122 is disposed on the side of the second mold body 121, and the position of the first mounting plate 112 corresponds to the position of the second mounting plate 122. However, this is not limited to this. In other embodiments, the first mounting plate 112 and the second mounting plate 122 are disposed at intervals, and the first mold body 111 and the second mold body 121 are both disposed between the first mounting plate 112 and the second mounting plate 122. The position of the first mounting plate 112 relative to the first mold body 111 and the position of the second mounting plate 122 relative to the second mold body 121 are not specifically limited.

[0057] In this embodiment, the number of the first mounting plate 112, the second mounting plate 122, the eccentric cam mechanism 130, the pull rod 140 and the locking mechanism 150 are all two. The two first mounting plates 112 are relatively arranged on both sides of the first mold body 111, and the two second mounting plates 122 are relatively arranged on both sides of the second mold body 121. Each eccentric cam mechanism 130 is installed on a first mounting plate 112 and connected to a pull rod 140. Each locking mechanism 150 is installed on a second mounting plate 122. The two eccentric cam mechanisms 130, the two pull rods 140 and the two locking mechanisms 150 work together to achieve simultaneous locking of both sides of the grouting mold, further improve the locking effect, and ensure product quality. However, it is not limited to this. In other embodiments, the number of the first mounting plate 112, the second mounting plate 122, the eccentric cam mechanism 130, the pull rod 140 and the locking mechanism 150 can all be four, or can all be six. The number of the first mounting plate 112, the second mounting plate 122, the eccentric cam mechanism 130, the pull rod 140 and the locking mechanism 150 is not specifically limited.

[0058] Preferably, the eccentric cam mechanism 130 is installed on a side of the first mounting plate 112 away from the second mounting plate 122, and the first mounting plate 112 can support and fix the eccentric cam mechanism 130; the locking mechanism 150 is installed on a side of the second mounting plate 122 away from the first mounting plate 112, and the second mounting plate 122 can support and fix the locking mechanism 150; the pull rod 140 is arranged to pass through the first mounting plate 112 and the second mounting plate 122 in sequence to ensure the locking effect of the first mounting plate 112 and the second mounting plate 122.

[0059] The pull rod 140 includes a sleeve portion 141, a connecting portion 142 and a matching portion 143 which are connected in sequence. The sleeve portion 141 and the matching portion 143 are arranged at two ends of the connecting portion 142 in a relative manner, and the sleeve portion 141, the connecting portion 142 and the matching portion 143 are arranged to extend in a straight line. Specifically, the sleeve portion 141 cooperates with the eccentric cam mechanism 130, and the eccentric cam mechanism 130 can drive the entire pull rod 140 to move through the sleeve portion 141; the matching portion 143 cooperates with the locking mechanism 150, and the locking mechanism 150 can limit the relative position of the pull rod 140 and the second mounting plate 122 through the matching portion 143.

[0060] The eccentric cam mechanism 130 includes a mounting frame 131, a rotary drive member 132 and an eccentric cam 133. The mounting frame 131 is connected to the first mounting plate 112 of the first module 110, and the first mounting plate 112 is used to fix the mounting frame 131. The rotary drive member 132 is mounted on the mounting frame 131 and connected to the eccentric cam 133. The rotary drive member 132 is used to drive the eccentric cam 133 to rotate. Specifically, the eccentric cam 133 extends into the sleeve portion 141 and is rotatably matched with the sleeve portion 141. The eccentric cam 133 and the sleeve portion 141 are both circular. The eccentric cam 133 can rotate relative to the sleeve portion 141, and the sleeve portion 141 can limit the eccentric cam 133. In the process of the rotary drive member 132 driving the eccentric cam 133 to rotate, the pull rod 140 moves under the cooperation of the eccentric cam 133 and the sleeve portion 141 until it reaches a preset position.

[0061] Furthermore, the eccentric cam 133 is provided with an axis 1331, and the rotary driving member 132 is connected to the axis 1331 of the eccentric cam 133, so as to drive the eccentric cam 133 to rotate. The eccentric cam 133 is relatively provided with a proximal end 1332 and a distal end 1333, wherein the distance between the proximal end 1332 and the axis 1331 is the smallest, and the distance between the distal end 1333 and the axis 1331 is the largest.

[0062] It should be noted that a first force point is formed between the sleeve portion 141 and the eccentric cam 133, and the first force point is the abutment point between the distal end 1333 of the eccentric cam 133 and the sleeve portion 141, and the sleeve portion 141 and the eccentric cam 133 are subjected to an interaction force at the position of the first force point; a second force point is formed between the rotary drive member 132 and the eccentric cam 133, and the second force point is the connection point between the rotary drive member 132 and the eccentric cam 133, and the rotary drive member 132 is connected to the mounting bracket 131. The eccentric cam 133 is connected to the mounting bracket 131, and the axis 1331 of the eccentric cam 133 is located in the middle of the output shaft of the rotary drive member 132, so the second force point is also the force point of the mounting bracket 131, and the rotary drive member 132 and the mounting bracket 131 are subjected to an interaction force at the position of the second force point; a third force point is formed between the matching portion 143 and the locking mechanism 150, and the third force point is the abutment point between the matching portion 143 and the locking mechanism 150, and the matching portion 143 and the locking mechanism 150 are subjected to an interaction force at the position of the third force point.

[0063] Specifically, the first force point and the second force point form a first connecting line, and the first force point and the third force point form a second connecting line. When the pull rod 140 moves to the preset position, the angle between the first connecting line and the second connecting line ranges from 0 to 8 degrees, so as to ensure that the pull rod 140 can achieve mechanical self-locking, thereby locking the first mounting plate 112 and the second mounting plate 122. For ease of understanding, the first force point is represented as a, the second force point is represented as b, the third force point is represented as c, and the angle between the first connecting line and the second connecting line is represented as A.

[0064] 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 pull rod 140 reaches the dead point position. At this time, the mechanical self-locking effect is better, and the first mounting plate 112 and the second mounting plate 122 can be further locked, which is stable and reliable.

[0065] It should be noted that after the first module 110 and the second module 120 are molded together, the pull rod 140 is set through the second mounting plate 122. At this time, the locking mechanism 150 is first used to cooperate with the pull rod 140 to fix the relative position of the pull rod 140 and the second mounting plate 122, and then the rotating drive member 132 is used to drive the eccentric cam 133 to rotate, so as to drive the pull rod 140 to move to a preset position, so that the first force point, the second force point and the third force point reach the specified position range, and then 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 133 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 mounting plate 112 and the second mounting plate 122 are locked to prevent the first mold body 111 and the second mold body 121 from relative movement.

[0066] Preferably, the eccentric cam mechanism 130 further includes a bearing 134. The bearing 134 is sleeved outside the eccentric cam 133 and arranged in the sleeve portion 141. The bearing 134 can reduce the friction force of the eccentric cam 133 rotating relative to the sleeve portion 141 to reduce energy consumption, ensure the stability of the rotation of the eccentric cam 133, and thus improve the reliability of the locking function.

[0067] The locking mechanism 150 includes a locking driver 151 and a locking member 152. The locking driver 151 is mounted on the second mounting plate 122 of the second module 120 and is connected to the locking member 152. The second mounting plate 122 is used to carry and position the locking driver 151. The locking member 152 is used to cooperate with the pull rod 140 to achieve the locking function. Specifically, the locking driver 151 can drive the locking member 152 to move so that the locking member 152 cooperates with the matching portion 143 of the pull rod 140; the locking driver 151 can also drive the locking member 152 to move in the opposite direction so that the locking member 152 and the matching portion 143 of the pull rod 140 are released from the matching state.

[0068] In this embodiment, the matching portion 143 is provided with a matching groove 1431, and the matching groove 1431 is used for the locking mechanism 150 to be inserted, so as to realize the matching function between the locking mechanism 150 and the pull rod 140. Specifically, the opening direction of the matching groove 1431 is the same as the movement direction of the locking member 152, and the locking driving member 151 can drive the locking member 152 to extend into or retract out of the matching groove 1431, so as to realize the matching or dismatching between the locking member 152 and the pull rod 140.

[0073] In this embodiment, the matching portion 143 of the pull rod 140 includes a matching section 1432 and a stop section 1433 connected to each other. One end of the matching section 1432 away from the stop section 1433 is connected to the connecting portion 142 (may be integrally formed, or may be threaded, welded, or riveted, etc.), the cross-sectional area of ​​the stop section 1433 is larger than the cross-sectional area of ​​the matching section 1432, the matching section 1432 is used to match with the locking mechanism 150, and the stop section 1433 is used to abut against the locking mechanism 150, when the matching section 1432 is matched with the locking member 152 of the locking mechanism 150, the stop section 1433 can stop and limit the locking member 152 to prevent the locking member 152 from being separated from the matching section 1432, thereby ensuring the locking effect.

[0074] The locking member 152 includes a first clamp arm 1521 and a second clamp arm 1522. The first clamp arm 1521 and the second clamp arm 1522 are arranged opposite to each other, and the locking driving member 151 is connected to the first clamp arm 1521 and the second clamp arm 1522 at the same time. The locking driving member 151 can drive the first clamp arm 1521 and the second clamp arm 1522 to move synchronously, so that the matching section 1432 of the pull rod 140 is clamped between the first clamp arm 1521 and the second clamp arm 1522, and the stopping section 1433 of the pull rod 140 is abutted against the first clamp arm 1521 and the second clamp arm 1522 at the same time.

[0075] In this embodiment, the locking member 152 also includes a connecting arm 1523, which is fixedly connected between the first clamp arm 1521 and the second clamp arm 1522. The locking drive member 151 is connected to the connecting arm 1523, and the locking drive member 151 can synchronously drive the first clamp arm 1521 and the second clamp arm 1522 to move through the connecting arm 1523.

[0076] Furthermore, the locking member 152 is arranged in a U shape, the first clamp arm 1521 and the second clamp arm 1522 are arranged in parallel and spaced apart, and the first clamp arm 1521, the connecting arm 1523 and the second clamp arm 1522 together form a bayonet 1524. The locking driving member 151 is a cylinder, an oil cylinder or an electric cylinder, and the locking driving member 151 is used to drive the locking member 152 to approach the pull rod 140 along the opening direction of the bayonet 1524 until the matching section 1432 of the pull rod 140 is clamped in the bayonet 1524, so as to achieve the matching of the locking member 152 and the pull rod 140, so that the stop section 1433 of the pull rod 140 is simultaneously against the first clamp arm 1521, the connecting arm 1523 and the second clamp arm 1522.

[0077] In this embodiment, the locking drive member 151 is a pneumatic cylinder, a hydraulic cylinder or an electric cylinder.

[0078] The beneficial effects of the lightweight grouting machine 100 provided by the embodiment of the utility model are the same as those of the first embodiment, and will not be described in detail here.

[0079] Third embodiment

[0080] Please refer to Figure 6 The embodiment of the utility model provides a lightweight grouting molding machine 100. Compared with the second embodiment, the difference of this embodiment is that the structure of the locking mechanism 150 is different.

[0081] In this embodiment, the locking member 152 no longer includes the connecting arm 1523, and the first clamping arm 1521 and the second clamping arm 1522 are separately arranged and no longer connected by the connecting arm 1523. The locking driving member 151 is a pneumatic cylinder, an oil cylinder or an electric cylinder, and the locking driving member 151 is relatively provided with a first piston rod 1511 and a second piston rod 1512, and the locking driving member 151 can synchronously drive the first piston rod 1511 and the second piston rod 1512 to extend or shorten. Specifically, the first piston rod 1511 is connected to the first clamping arm 1521, and the second piston rod 1512 is connected to the second clamping arm 1522. The first piston rod 1511 and the second piston rod 1512 can be synchronously extended and retracted to drive the first clamping arm 1521 and the second clamping arm 1522 to move closer to or away from each other, thereby realizing the matching or dismatching of the locking member 152 and the pull rod 140.

[0082] Furthermore, the pull rod 140 is arranged between the first clamp arm 1521 and the second clamp arm 1522. When the locking drive 151 drives the first clamp arm 1521 and the second clamp arm 1522 to approach each other to the first extreme position through the first piston rod 1511 and the second piston rod 1512, the matching section 1432 of the pull rod 140 is clamped between the first clamp arm 1521 and the second clamp arm 1522, so that the stop section 1433 is simultaneously abutted against the first clamp arm 1521 and the second clamp arm 1522; when the locking drive 151 drives the first clamp arm 1521 and the second clamp arm 1522 to move away from each other to the second extreme position through the first piston rod 1511 and the second piston rod 1512, the matching section 1432 is separated from the first clamp arm 1521 and the second clamp arm 1522.

[0083] Preferably, the first clamp arm 1521 is provided with a groove 1525 for the pull rod 140 to be embedded therein to ensure the clamping effect, thereby enhancing the locking effect. In this embodiment, the groove 1525 is arranged in a semicircular shape, and the shape of the groove 1525 matches the shape of the matching section 1432 of the pull rod 140 to further enhance the clamping effect.

[0084] In this embodiment, the specific structure of the second clamping arm 1522 is the same as the specific structure of the first clamping arm 1521 , and will not be described again.

[0085] The beneficial effects of the lightweight grouting machine 100 provided by the embodiment of the utility model are the same as those of the first embodiment, and will not be described in detail here.

[0086] Fourth embodiment

[0087] Please refer to Figure 7 and Figure 8 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 matching structure of the locking mechanism 150 and the pull rod 140.

[0088] In this embodiment, a locking tongue 144 is provided at the end of the pull rod 140, and the locking tongue 144 is non-circular. The pull rod 140 is sequentially arranged through the first mounting plate 112 and the second mounting plate 122, and the locking tongue 144 is arranged at one end of the pull rod 140 extending out of the second mounting plate 122. Specifically, the locking member 152 is provided with a locking groove 1526, and the shape of the locking groove 1526 matches the shape of the locking tongue 144. The locking groove 1526 is used for the locking tongue 144 of the pull rod 140 to extend into, and the locking driving member 151 is used to drive the locking member 152 to rotate a preset angle (generally 90 degrees) so that the locking groove 1526 and the locking tongue 144 are staggered, thereby realizing the locking of the locking member 152 and the pull rod 140, and then facilitating the locking function of the first mounting plate 112 and the second mounting plate 122.

[0089] Furthermore, the locking driver 151 is a driving motor, a hydraulic motor or a pneumatic motor, and the locking driver 151 is used to drive the locking member 152 to rotate so that the position of the locking groove 1526 corresponds to or staggers with the position of the locking tongue 144. When the position of the locking groove 1526 corresponds to the position of the locking tongue 144, the locking tongue 144 can be retracted from the locking groove 1526 to facilitate mold opening; when the position of the locking groove 1526 is staggered with the position of the locking tongue 144, the locking member 152 is locked with the pull rod 140 to achieve the locking function of the first mounting plate 112 and the second mounting plate 122.

[0090] Preferably, the locking mechanism 150 also includes a fixed shell 153, which is connected to the second mounting plate 122 of the second module 120, and the locking drive 151 is installed in the mounting shell. The second mounting plate 122 can position the locking drive 151 through the mounting shell to ensure the stability of the locking drive 151 driving the locking drive 152 to rotate.
