Description

Technical Field

[0001] The utility model relates to the technical field of mold processing, in particular to a mold processing guide device. Background Art

[0002] The mold is a certain complex-shaped component that is mass-produced through precise processing methods. It is usually composed of several groups of parts. After being combined into one, a molding cavity is formed inside it. The shape of the cavity is the shape of the model after molding. When the mold is combined, it is necessary to use a guide device. The guide device is positioned by connecting the guide column fixed on the top of the lower module with the guide sleeve set inside the upper module, so as to achieve stability and accuracy in the overlap of the upper and lower molds.

[0003] However, when using the mold, since there are multiple ball bearings in the guide sleeve to reduce the wear between the guide pin and the guide sleeve, it is still necessary to replace the guide sleeve after long-term use to ensure the accuracy of the overlap of the upper and lower molds. Since there are a large number of fixing screws between the molds, it is more cumbersome to remove the guide sleeve, which takes a lot of time and is inconvenient for workers to replace the guide sleeve for the guide device of the mold. Utility Model Content

[0004] In view of the deficiencies of the prior art, the utility model provides a mold processing guide device, which solves the technical problem that it is inconvenient for workers to disassemble the guide sleeve in the guide device, thereby achieving the purpose of facilitating workers to maintain the guide device of the mold.

[0005] In order to solve the above technical problems, the utility model provides the following technical solutions:

[0006] A mold processing guide device, comprising an upper mold and a lower mold installed on one side of the upper mold, wherein one end of the upper mold is provided with a plurality of guide rods, the lower mold is provided with a plurality of guide holes, each of the guide holes is provided with a guide sleeve connected with the guide rod, and the lower mold is provided with a positioning mechanism for conveniently disassembling or installing the guide sleeve;

[0007] The positioning mechanism comprises an annular groove arranged on the inner surface of the guide sleeve, and an annular inclined surface is arranged on one side of the guide sleeve. A through groove connected to the guide hole is arranged in the lower mold, and a fixing piece for fixing the guide sleeve in the guide hole is arranged in the through groove.

[0008] Furthermore, the through groove penetrates to the outside of the lower mold, and the through groove is located on one side of the central axis of the guide hole.

[0009] Furthermore, the fixing member includes a first spring arranged in a through groove, a connecting rod slidably provided in the through groove and fixedly connected to the first spring, two rectangular tubes are symmetrically provided on the surface of the connecting rod, a second spring is provided in each of the two rectangular tubes, and a first trapezoidal block slidably provided in the rectangular tube and fixedly connected to the second spring.

[0010] Furthermore, limiting grooves are provided on both sides of the through groove, and limiting blocks sliding in the limiting grooves are provided on the surface of the connecting rod.

[0011] Furthermore, the connecting rod is semicircular, and a push rod is provided at one end of the connecting rod.

[0012] Furthermore, a plurality of second trapezoidal blocks are arranged in the annular groove, and trapezoidal grooves for the first trapezoidal blocks to slide into are arranged between adjacent second trapezoidal blocks.

[0013] By means of the above technical solution, the utility model provides a mold processing guide device, which has at least the following beneficial effects:

[0014] 1. Due to the setting of the positioning mechanism of the utility model, when the guide sleeve slides in the guide hole, the first trapezoidal block is stuck in the annular groove, limiting the up and down movement of the guide sleeve in the guide hole, and pulling the push rod to compress the first spring, so that the connecting rod drives the first trapezoidal block to move laterally in the through groove, and separates the first trapezoidal block from the annular groove, which is convenient for workers to take the guide sleeve out of the guide hole, and under the action of the first spring, the connecting rod drives the first trapezoidal block to reset in the through groove, which is convenient for workers to operate the positioning mechanism and conveniently remove or install the guide sleeve in the guide hole.

[0015] 2. Due to the arrangement of the second trapezoidal block and the trapezoidal groove, the first trapezoidal block can slide into the trapezoidal groove by manually rotating the guide sleeve at a certain angle. At this time, the inclined surfaces of the first trapezoidal block and the second trapezoidal block contact and squeeze each other to generate static friction, thereby limiting the rotation of the guide sleeve in the guide hole, which is beneficial to reducing the wear of the first trapezoidal block when it rotates in the annular groove.

DETAILED DESCRIPTION

[0024] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0025] Example 1

[0026] When installing or removing the guide sleeve 5 in the lower mold 2, the existing guide device needs to screw multiple fixing screws in the entire lower mold 2, so that the lower mold 2 is formed into multiple parts, which increases the time for workers to maintain the guide device, and the many parts that need to be removed need to be installed one by one in sequence during installation to prevent installation misalignment, increase the workload of workers, and are not conducive to workers replacing the guide sleeve 5 for the equipment. This embodiment provides a mold processing guide device, such as Figure 1-Figure 4 As shown, it includes an upper mold 1 and a lower mold 2 installed on one side of the upper mold 1, a plurality of guide rods 3 are provided at one end of the upper mold 1, a plurality of guide holes 4 are provided in the lower mold 2, guide sleeves 5 which are sleeved with the guide rods 3 are provided in the guide holes 4, and a positioning mechanism 6 for conveniently disassembling or installing the guide sleeves 5 is provided in the lower mold 2. When workers regularly check or replace the guide sleeves 5 of the equipment, they will separate the upper mold 1 from the lower mold 2 and the guide rods 3 from the guide sleeves 5. At this time, the workers can pull the positioning mechanism 6 on one side of the lower mold 2 to quickly separate the guide sleeves 5 from the guide holes 4. When installing the guide sleeves 5 in the guide holes 4 in the lower mold 2, one end of the guide sleeves 5 can be directly slid into the guide holes 4, so that the guide sleeves 5 are squeezed with the positioning mechanism 6, thereby quickly fixing the new guide sleeves 5 in the guide holes 4.

[0027] Since workers need to tighten multiple fixing screws when installing or removing the guide sleeve 5 in the guide hole 4, it is inconvenient for workers to install or remove the guide sleeve 5, and the time cost of workers to maintain the equipment is increased. The positioning mechanism 6 includes an annular groove 61 provided on the inner surface of the guide sleeve 5. When the guide sleeve 5 slides in the guide hole 4, the annular groove 61 contacts the fixing piece 64, and the guide sleeve 5 can be fixed in the guide hole 4 at this time. An annular inclined surface 62 is provided on one side of the guide sleeve 5, which can be squeezed with the fixing piece 64 to reduce damage to the surface of the guide sleeve 5. A through groove 63 connected to the guide hole 4 is provided in the lower mold 2. When the worker removes the guide sleeve 5 in the guide hole 4, the worker can pull one end of the fixing piece 64 in the through groove 63 to move to the other end, so that the fixing piece 64 is separated from the annular groove 61. At this time, the worker can manually take the guide sleeve 5 out of the guide hole 4. The through groove 63 is provided with a fixing piece 64 for fixing the guide sleeve 5 in the guide hole 4. 5 slides on the surface and slides into the annular groove 61 to limit the guide sleeve 5 from moving up and down in the guide hole 4. Since the through groove 63 penetrates to the outside of the lower mold 2 and the through groove 63 is located on one side of the central axis of the guide hole 4, when the worker inserts the new guide sleeve 5 into the guide hole 4, the annular inclined surface 62 on one side of the guide sleeve 5 will contact and squeeze the fixing piece 64, so that the fixing piece 64 moves along the annular groove 61 to the surface of the guide sleeve 5, and continues to move until the fixing piece 64 contacts the annular groove 61. At this time, the guide sleeve 5 stops and is fixed at this position in the guide hole 4. When the worker needs to remove the guide sleeve 5 in the guide hole 4, the fixing piece 64 located at one end of the through groove 63 can be pulled, and the fixing piece 64 is also located on the horizontal plane of the central axis of one side of the guide sleeve 5, so that the fixing piece 64 moves a certain distance in the through groove 63, and the fixing piece 64 is separated from the annular groove 61, thereby releasing the restriction on the guide sleeve 5, which is conducive to the worker to easily remove the guide sleeve 5 from the guide hole 4.

[0028] When the guide sleeve 5 is removed from the guide hole 4, a large number of fixing screws need to be removed, which increases the time for workers to install or remove the guide sleeve 5, which is not conducive to workers replacing the guide sleeve 5 for the lower mold 2 in daily work. The fixing member 64 includes a first spring 641 arranged in the through groove 63, a connecting rod 642 fixedly connected to the first spring 641 is slidably arranged in the through groove 63, and two rectangular tubes 643 are symmetrically arranged on the surface of the connecting rod 642, and the second spring 644 is arranged in each of the two rectangular tubes 643, and a connecting rod 642 is slidably arranged in the through groove 63 and fixedly connected to the first spring 641. The first trapezoidal block 645 is fixedly connected with the second spring 644. Since the through groove 63 is provided with a limit groove 646 on both sides, the surface of the connecting rod 642 is provided with a limit block 647 sliding in the limit groove 646. The connecting rod 642 is semicircular, and a push rod 648 is provided at one end of the connecting rod 642. When the guide sleeve 5 slides in the guide hole 4, the annular inclined surface 62 contacts and squeezes the first trapezoidal block 645, so that the first trapezoidal block 645 squeezes the second spring 644 to contract. At this time, the first trapezoidal block 645 moves toward the inside of the rectangular tube 643. When When the first trapezoidal block 645 moves to the annular groove 61, the first trapezoidal block 645 moves to the inside of the annular groove 61 under the action of the second spring 644. At this time, the first trapezoidal block 645 penetrates into the inside of the guide sleeve 5, and the width of the annular groove 61 is the same as the width of the first trapezoidal block 645, so that the first trapezoidal block 645 limits the guide sleeve 5 to move up and down in the guide hole 4. When the worker pulls the push rod 648 to compress the first spring 641, the limit block 647 on the surface of the connecting rod 642 slides in the limit groove 646 , so that the connecting rod 642 moves linearly in the through groove 63. When the first trapezoidal block 645 is separated from the annular groove 61, the guide sleeve 5 is released from the restriction in the guide hole 4 and can be manually taken out by a worker. Since the connecting rod 642 is semicircular and slides in the through groove 63, the annular groove 61 on the surface of the guide sleeve 5 is simultaneously restricted by multiple first trapezoidal blocks 645, which is conducive to firmly restricting the guide sleeve 5 in the guide hole 4 and preventing the lower mold 2 and the upper mold 1 from moving, resulting in a decrease in the accuracy of the guide device.

[0029] Example 2

[0030] When the annular groove 61 on the surface of the guide sleeve 5 is slipped into and stuck by the plurality of first trapezoidal blocks 645, the guide sleeve 5 can still rotate in the guide hole 4 under the action of external force, thereby increasing the wear of the first trapezoidal blocks 645 in the annular groove 61, which is not conducive to the long-term use of the positioning mechanism 6. Based on Example 1, Figure 5As shown, a plurality of second trapezoidal blocks 7 are provided in the annular groove 61, and a trapezoidal groove 8 for the first trapezoidal block 645 to slide into is provided between adjacent second trapezoidal blocks 7. When the first trapezoidal block 645 slides into the annular groove 61, the first trapezoidal block 645 will contact the second trapezoidal block 7, and the second trapezoidal block 7 is in a compressed state. The worker can manually rotate the guide sleeve 5 to make the first trapezoidal block 645 actively slide in the annular groove 61. When the first trapezoidal block 645 contacts the trapezoidal groove 8 during sliding, the shapes of the trapezoidal groove 8 and the first trapezoidal block 645 are completely matched, and the first trapezoidal block 645 will be in close contact with the trapezoidal groove 8 under the action of the second spring 644. When the mold 2 moves driven by external force, the inclined surface of the first trapezoidal block 645 and the inclined surface of the second trapezoidal block 7 contact and squeeze each other to generate a certain static friction force, thereby preventing the first trapezoidal block 645 from rotating in the annular groove 61 and maintaining the long-term use of the positioning mechanism 6.
