A mold opening and closing mechanism

Abstract

The present invention discloses a mold opening and closing mechanism, which mainly includes a combined mold and a driving mechanism. When a rotary drive mode is adopted, the motor drives the screw to rotate through a commutator and a transmission shaft, and the partition connected to the screw moves forward or backward with the rotation of the screw. Since the two partitions of the same group of combined molds are respectively connected to the positive and negative threads, when the screw rotates, the two partitions move toward or away from each other at the same time, so as to achieve mold closing or mold opening; and when a direct drive mode is adopted, the driving cylinders are respectively arranged on both sides, and the driving cylinder on one side is fixedly connected to the partition on one side of the combined mold through a driving frame and a driving rod, while the driving cylinder on the other side is fixedly connected to the partition on the other side of the combined mold. When the driving cylinders on both sides are pushed toward the middle or pulled toward both sides at the same time, the partitions on both sides of the combined mold move toward or away from each other at the same time, so as to achieve mold closing or mold opening. The present invention also has the advantages of simple structure, convenient operation and easy implementation.

Description

Technical Field

[0001] The invention relates to the technical field of kiln structures, and in particular to an opening and closing mold mechanism on a kiln for producing composite light-weight wall panels. Background Art

[0002] In the existing kiln for producing composite lightweight wall panels, when closing the mold, the first partition on one side needs to be stacked layer by layer and pushed toward the last partition on the other side (the partition is fixed). When opening the mold, the first partition on one side needs to be stacked layer by layer and pulled back to the original position (opening the mold). This mold opening and closing method has the following disadvantages:

[0003] 1. During the mold opening and closing process, the stroke of the first partition is the longest. With the increase of partitions (the mold car body is lengthened), the stroke required for mold opening and closing will be longer, which is not conducive to saving mold opening and closing time and improving production efficiency;

[0004] 2. The composite ceramic plate needs to be loaded before mold closing. Therefore, during the long-stroke mold opening and closing process, the ceramic plate will shift, offset, and the displacement of both ends will be asynchronous.

[0005] 3. When the position of the ceramic plate is offset, it needs to be corrected in time, otherwise poor sealing and leakage will occur during grouting. However, under this mold opening and closing method, the previously molded partition needs to be re-molded, and then re-molded after correction. Therefore, the production efficiency is low and the time cost is high.

[0006] Therefore, the prior art needs to be further improved and perfected. Summary of the invention

[0007] The purpose of the present invention is to overcome the deficiencies of the prior art and provide a mold opening and closing mechanism for a kiln used for producing composite light-weight wall panels.

[0008] The purpose of the present invention is achieved through the following technical solutions:

[0009] A mold opening and closing mechanism mainly includes a combined mold and a driving mechanism for driving the combined mold to open or close the mold. The combined mold is composed of a top plate, a bottom plate, a side plate, and two partitions. A plurality of combined molds are arranged side by side on a guide rail. The driving end of the driving mechanism is respectively connected to the partitions of each group of combined molds, and drives the two partitions to move toward or away from each other at the same time, so as to realize the closing or opening of the combined mold.

[0010] Further, the driving mechanism provided by the present invention can adopt a rotary drive type or a direct drive type. When the rotary drive type is adopted, the driving mechanism drives the partitions to move toward or away from each other by forward or reverse rotation, and mainly includes a motor, a first commutator, a second commutator, a third commutator, a first transmission shaft, a second transmission shaft, and a screw. The input end of the first commutator is connected to the output shaft of the motor, and the output end is connected to one end of the first transmission shaft. The input end of the second commutator is connected to the other end of the first transmission shaft, and the output end is connected to one end of the second transmission shaft. The input end of the third commutator is connected to the other end of the second transmission shaft, and the output end is connected to the screw, so that the rotation of the motor is synchronously transmitted to the screw, and the screw is driven to rotate. The partitions of each group of modular molds are respectively threadedly connected to the screw. The two ends of the screw are fixed to the frame by bearings, and the threads on the screw are divided into positive thread segments and reverse thread segments. The same group of partitions are respectively connected to the positive thread segments and the reverse thread segments, so that the forward and reverse rotation of the screw drives the two partitions to move toward or away from each other.

[0011] As a preferred solution of the present invention, the screw rods are arranged in four groups, which are arranged perpendicular to the partition and are respectively located at the four corners of the partition, and drive the partition to move at the same time.

[0012] Furthermore, when the direct drive is adopted, the driving mechanism drives the partition to move toward or away from each other by pushing forward or backward, and mainly includes a guide rod, a first driving cylinder, a first driving frame, a first driving rod, a second driving cylinder, a second driving frame, and a second driving rod. The two ends of the guide rod are fixed on the frame and are arranged perpendicular to the partition. The partition is connected to the guide rod and can slide on the guide rod. The first driving cylinder is arranged on one side of the combined mold, and its piston end is connected to the first driving frame to push the first driving frame to move forward and backward as a whole. One end of the first driving rod is fixedly connected to the first driving frame, and the other end passes through the combined mold and is fixedly connected to the partition on one side of the combined mold. The second driving cylinder is arranged on the other side of the combined mold, and its piston end is connected to the second driving frame to push the second driving frame to move forward and backward as a whole. One end of the second driving rod is fixedly connected to the second driving frame, and the other end passes through the combined mold and is fixedly connected to the partition on the other side of the combined mold.

[0013] As a preferred solution of the present invention, the connection between the first driving rod and the partition plate on one side and the connection between the second driving rod and the partition plate on the other side are staggered.

[0014] As a preferred solution of the present invention, the guide rods are located above the partition and are provided in two groups.

[0015] The working process and principle of the present invention are as follows: when the rotary drive mode is adopted, the motor rotates and drives the screw to rotate through the commutator and the transmission shaft, and the partition connected to the screw will move forward or backward with the rotation of the screw. Since the two partitions of the same group of combined molds are respectively connected to the positive and negative threads, when the screw rotates, the two partitions move toward or away from each other at the same time, so as to achieve the mold closing or mold opening; and when the direct drive mode is adopted, the driving cylinders are respectively arranged on both sides, and the driving cylinder on one side is fixedly connected to the partition on one side of the combined mold through the driving frame and the driving rod, while the driving cylinder on the other side is fixedly connected to the partition on the other side of the combined mold. When the driving cylinders on both sides are pushed toward the middle or pulled toward both sides at the same time, the partitions on both sides of the combined mold move toward or away from each other at the same time, so as to achieve the mold closing or mold opening. The present invention also has the advantages of simple structure, convenient operation and easy implementation.

[0016] Compared with the prior art, the present invention also has the following advantages:

[0017] (1) The mold opening and closing mechanism provided by the present invention uses a motor to drive the screw to rotate, thereby driving the partitions connected to the positive and negative threads to move toward or away from each other. This mold opening and closing method has a short stroke (30 mm). Compared with the traditional mold opening and closing method (stroke 420 mm), it can significantly reduce the mold opening and closing stroke (shortened by 14 times) and time (saving 14 times), greatly improving production efficiency.

[0018] (2) The mold opening and closing mechanism provided by the present invention adopts a threaded connection method between the screw rod and the partition plate, which has a self-locking characteristic. Therefore, the mold will be automatically locked after the mold is closed, and there is no need to add additional devices to lock the mold.

[0019] (3) The screw rod provided by the present invention is connected to the four corners of the back plate, and has high positioning accuracy, which can achieve synchronous and joint advancement of the partitions and prevent the composite plate from running off the track, so the quality rate of the products produced is high.

[0020] (4) The position of each composite plate of the mold opening and closing mechanism provided by the present invention is fixed relative to the partition plate, which is convenient for positioning and locking during mold closing, and is also convenient for workers to load and unload, and is also conducive to improving the automation level of the production line.

[0021] (5) Each composite plate on the mold opening and closing mechanism provided by the present invention does not affect each other. Even if one of them has a problem, it only needs to be processed without the need to re-open the mold, which greatly saves the time required for mold opening and closing and significantly improves production efficiency.

[0022] (6) The mold opening and closing mechanism provided by the present invention solves the problem of displacement of the composite plate during the mold closing process on the existing production line by changing the traditional mold opening and closing method, thereby greatly improving the positioning accuracy of the composite plate, saving mold opening and closing time, and significantly improving production efficiency.

DETAILED DESCRIPTION

[0032] In order to make the purpose, technical solutions and advantages of the present invention more clear and explicit, the present invention is further described below with reference to the accompanying drawings and embodiments.

[0033] Embodiment 1:

[0034] like Figures 1 to 7As shown, this embodiment discloses a mold opening and closing mechanism, which mainly includes a combined mold 1 and a driving mechanism 2 for driving the combined mold 1 to open or close the mold. The combined mold 1 is composed of a top plate, a bottom plate, a side plate, and two partitions. Several combined molds 1 are arranged side by side on a guide rail. The driving end of the driving mechanism 2 is respectively connected to the partitions of each group of combined molds 1, and drives the two partitions to move toward or away from each other at the same time, so as to achieve the closing or opening of the combined mold 1.

[0035] Furthermore, the driving mechanism 2 provided by the present invention can adopt a rotary drive type or a direct drive type. When the rotary drive type is adopted, the driving mechanism 2 drives the partitions to move toward or away from each other by forward or reverse rotation, and mainly includes a motor 3, a first commutator 4, a second commutator 5, a third commutator 6, a first transmission shaft 7, a second transmission shaft 8, and a screw 9. The input end of the first commutator 4 is connected to the output shaft of the motor 3, and the output end is connected to one end of the first transmission shaft 7. The input end of the second commutator 5 is connected to the other end of the first transmission shaft 7, and the output end is connected to one end of the second transmission shaft 8. The input end of the third commutator 6 is connected to the other end of the second transmission shaft 8, and the output end is connected to the screw 9, so that the rotation of the motor 3 is synchronously transmitted to the screw 9, and the screw 9 is driven to rotate. The partitions of each group of combined molds 1 are respectively threadedly connected to the screw 9. The two ends of the screw rod 9 are fixed on the frame through bearings. The thread on the screw rod 9 is divided into a positive thread segment and a negative thread segment. The same group of partitions are respectively connected to the positive thread segment and the negative thread segment, so that the positive and negative rotation of the screw rod 9 drives the two partitions to move toward or away from each other.

[0036] As a preferred solution of the present invention, the screw rods 9 are arranged in four groups, which are arranged perpendicular to the partition and are respectively located at the four corners of the partition, and drive the partition to move at the same time.

[0037] Furthermore, when the direct drive is adopted, the driving mechanism 2 drives the partition to move toward or away from each other by pushing forward or backward, and mainly includes a guide rod 10, a first driving cylinder 11, a first driving frame 12, a first driving rod 13, a second driving cylinder 14, a second driving frame 15, and a second driving rod 16. The two ends of the guide rod 10 are fixed on the frame and are arranged perpendicular to the partition. The partition is connected to the guide rod 10 and can slide on the guide rod 10. The first driving cylinder 11 is arranged on one side of the combined mold 1, and its piston end is connected to the first driving frame 12, pushing the first driving frame 12 to move forward and backward as a whole. One end of the first driving rod 13 is fixedly connected to the first driving frame 12, and the other end passes through the combined mold 1 and is fixedly connected to the partition on one side of the combined mold 1. The second driving cylinder 14 is arranged on the other side of the combined mold 1, and its piston end is connected to the second driving frame 15, pushing the second driving frame 15 to move forward and backward as a whole. One end of the second driving rod 16 is fixedly connected to the second driving frame 15 , and the other end thereof penetrates through the combined mold 1 and is fixedly connected to the partition plate on the other side of the combined mold 1 .

[0038] As a preferred solution of the present invention, the connection between the first driving rod 13 and one side partition plate and the connection between the second driving rod 16 and the other side partition plate are staggered.

[0039] As a preferred solution of the present invention, the guide rods 10 are located above the partition and are provided in two groups.

[0040] The working process and principle of the present invention are as follows: when the rotary drive mode is adopted, the motor 3 rotates and drives the screw 9 to rotate through the commutator and the transmission shaft, and the partition connected to the screw 9 moves forward or backward with the rotation of the screw 9. Since the two partitions of the same group of combined molds 1 are respectively connected to the positive and negative threads, when the screw 9 rotates, the two partitions move toward or away from each other at the same time, so as to achieve the mold closing or mold opening; and when the direct drive mode is adopted, the driving cylinders are respectively arranged on both sides, and the driving cylinder on one side is fixedly connected to the partition on one side of the combined mold 1 through the driving frame and the driving rod, and the driving cylinder on the other side is fixedly connected to the partition on the other side of the combined mold 1. When the driving cylinders on both sides are pushed toward the middle or pulled toward both sides at the same time, the partitions on both sides of the combined mold 1 move toward or away from each other at the same time, so as to achieve the mold closing or mold opening. The present invention also has the advantages of simple structure, convenient operation and easy implementation.

[0041] The above embodiments are preferred implementation modes of the present invention, but the implementation modes of the present invention are not limited to the above embodiments. Any other changes, modifications, substitutions, combinations, and simplifications that do not deviate from the spirit and principles of the present invention should be equivalent replacement methods and are included in the protection scope of the present invention.
