Description

Technical Field

[0001] The utility model belongs to the technical field of mold fixing in an injection molding machine, and particularly relates to a mold pressing plate fixing structure. Background Art

[0002] During the production process of the injection molding machine, the mold needs to be replaced as the product changes. When replacing the mold, the mold fixing plate needs to be removed. The position of the platen needs to be re-fixed due to the different sizes of the mold. The platen fixing bolt and the mold locking bolt are the same bolt. When the nut is removed, the bolt often becomes loose. Frequent disassembly leads to frequent damage to the template fixing threaded holes.

[0003] Frequent disassembly of the pressure plate for different molds is rather cumbersome, which not only causes fixed wear, but also increases the operator's time and reduces work efficiency. Utility Model Content

[0004] In order to solve the technical problem in the background technology that the pressing plate of the injection molding machine is inconvenient to fix due to the continuous replacement of the mold during the production process, the purpose of the utility model is to provide a mold pressing plate fixing structure that can solve the above problem.

[0005] The technical solution to achieve the purpose of the utility model is: a mold pressure plate fixing structure, including a pressure plate and a pressure plate seat, the pressure plate seat is fixed on the mold placing plate, the pressure plate is rotatably installed on the pressure plate seat, one end of the pressure plate is pressed against the mold, and the other end of the pressure plate is provided with an adjustment device for adjusting the distance between the other end of the pressure plate and the pressure plate seat.

[0006] The pressing plate in this solution is rotatably installed on the pressing plate seat, similar to a seesaw. After one end of the pressing plate is pressed against the mold, the other end uses the adjusting device to exert force. After continuously pressing against the pressing plate seat, the reaction force is exerted on the other end of the pressing plate, so that the pressing plate can be ensured to be pressed tightly against the mold. And the pressing plate in this solution can be rotated when it is initially pressed against the mold, and can be adjusted according to different molds, reducing the need for tedious operations such as changing the pressing plate and changing the position of the pressing plate for different molds. And when the mold needs to be unloaded, there is no need to remove the entire clamping structure, only to loosen and rotate the pressing plate, so that the mold can be freed from the restraint of the pressing plate and can be easily moved from the mold placement plate. The structure is simple, the operation is flexible and convenient, and the work efficiency of the operator is greatly improved.

[0007] Furthermore, it also includes a rotating shaft, the pressure plate seat has a relatively arranged mounting ear, the mounting ear has a mounting hole, the pressure plate has a rotating shaft hole corresponding to the mounting hole, the rotating shaft is installed in the mounting hole and the rotating shaft hole, and the pressure plate is installed on the pressure plate seat by the cooperation of the rotating shaft, the mounting hole and the rotating shaft hole. At this time, the pressure plate rotates like a seesaw structure, and can be adjusted by rotation when different molds need to be pressed.

[0008] It also includes an anti-skid groove extending radially along the rotating shaft, and an anti-skid bolt corresponding to the anti-skid groove. The pressure plate is provided with an anti-skid bolt hole connected to the rotating shaft hole. The anti-skid bolt is installed in the anti-skid bolt hole and the end portion is located in the anti-skid groove. Since the rotating shaft is rotatably installed in the rotating shaft hole and the mounting hole, vibration will be generated during mechanical processing. In order to prevent the rotating shaft from sliding out of the rotating shaft hole and the mounting hole, a device to limit its sliding out is required. The anti-skid groove is an arc-shaped groove extending radially along the rotating shaft, which does not affect the rotation of the rotating shaft in the rotating shaft hole. After the anti-skid bolt is installed in the anti-skid bolt hole on the pressure plate, its end portion is also inserted into the anti-skid groove. The pressure plate is also restricted between the two mounting ears, so the rotating shaft will not slide out of the mounting hole.

[0009] Furthermore, the adjusting device is an adjusting bolt, the pressing plate has an adjusting bolt hole, the adjusting bolt is installed in the adjusting bolt hole, and the end of the adjusting bolt abuts against the pressing plate seat. When the end of the pressing plate needs to be pressed against the mold, the adjusting bolt on the other end is screwed so that it is continuously screwed into the adjusting bolt hole, and the adjusting bolt screw between the pressing plate and the pressing plate seat becomes longer, that is, the distance between the pressing plate and the pressing plate seat gradually increases at one end of the adjusting bolt, and the pressing plate is pressed against the mold.

[0010] Furthermore, the length of the adjusting bolt is greater than the sum of the maximum gap between the pressing plate and the pressing plate seat after the pressing plate is rotated and the thickness of the pressing plate. In other words, the length of the adjusting bolt is long enough to support the maximum distance adjustment between the pressing plate and the pressing plate at one end of the pressing plate where the adjusting bolt is located, thereby meeting its maximum functional role.

[0011] Furthermore, there is a gap between the lower end surface of the pressing plate and the pressing plate seat, and an abutting portion protruding downward is provided on one end of the pressing plate away from the adjusting device, and the abutting portion abuts against the mold. Since the abutting portion protrudes toward one end of the pressing plate seat, it will contact the mold first, thereby ensuring the movable distance between the pressing plate and the pressing plate seat to the greatest extent.

[0012] Furthermore, the mold placement plate has a T-slot, the pressure plate seat has a T-slot corresponding to the T-slot, and the T-slot is installed in the T-slot. Compared with the original bolt installation, this structure only requires the T-slot to slide into the T-slot without tightening the bolts, thereby preventing the problems of thread damage and slippage in the bolt hole and improving the installation efficiency.

[0013] Furthermore, the pressing plate and the pressing plate seat form a pressing unit. According to needs, a plurality of pressing units can be evenly distributed around the mold to ensure a pressing and fixing effect on the mold.

[0014] By adopting the above technical solution, the utility model has the following beneficial effects:

[0015] (1) The pressing plate is rotatably mounted on the pressing plate seat, which can reduce a series of problems caused by constantly disassembling the pressing plate. The pressing plate can be fixed or released by rotating, and the structure is simple and easy to use.

[0016] (2) Use an adjusting bolt between the end of the pressing plate away from the mold and the pressing plate to adjust, and tighten or loosen it evenly and conveniently;

[0017] (3) An anti-slip groove extending radially is also provided on the rotating shaft, and an anti-slip bolt is correspondingly provided on the pressure plate, which can effectively prevent the rotating shaft from slipping out of the rotating shaft hole and the mounting hole;

[0018] (4) A T-shaped mounting block is set at the bottom of the pressure plate seat and used in conjunction with the T-shaped slot on the mold placement plate to reduce the problem of bolt fixing and make installation more convenient. BRIEF DESCRIPTION OF THE DRAWINGS

The platen 3 in this solution is rotatably mounted on the platen seat 4, similar to a seesaw, after one end of the platen is pressed against the mold 1, the other end uses the adjustment device to exert force, and after continuously pressing against the platen seat 4, a reaction force is exerted on the other end of the platen 3, so that the platen 3 can be ensured to be pressed tightly against the mold 1. Moreover, the platen 3 in this solution can be rotated when initially pressed against the mold 1, and adjusted according to different molds 1, thereby reducing the cumbersome operations such as changing the platen 3 and changing the position of the platen 3 for different molds 1. When the mold 1 needs to be unloaded, it is not necessary to completely remove the clamping structure, but only to loosen and rotate the pressing plate 3, so that the mold 1 can be freed from the restraint of the pressing plate 3 and can be easily moved from the mold placement plate 2. The structure is simple, the operation is flexible and convenient, and the work efficiency of the operator is greatly improved.

[0027] Preferably, the mold placement plate 2 has a T-slot 15, and the pressure plate seat 4 has a T-slot mounting block 16 corresponding to the T-slot 15, and the T-slot mounting block 16 is installed in the T-slot 15. Compared with the original bolt installation, this structure only requires the T-slot mounting block 16 to slide into the T-slot 15, and does not need to tighten the bolts, thereby preventing problems such as damage to the threads in the bolt holes and slippage, and improving installation efficiency.

[0028] Preferably, the pressing plate 3 and the pressing plate seat 4 form a pressing unit. As required, a plurality of pressing units may be evenly distributed around the mold 1 to ensure a pressing and fixing effect on the mold 1 .

[0029] like Figure 3 and Figure 4As shown, the adjusting device is an adjusting bolt 12, and the pressing plate 3 has an adjusting bolt hole 13. The adjusting bolt 12 is installed in the adjusting bolt hole 13, and the end of the adjusting bolt 12 abuts against the pressing plate seat 4. When the end of the pressing plate 3 needs to be pressed against the mold 1, the adjusting bolt 12 on the other end is screwed so that it is continuously screwed into the adjusting bolt hole 13, and the screw of the adjusting bolt 12 between the pressing plate 3 and the pressing plate seat 4 becomes longer, that is, the distance between the pressing plate 3 and the pressing plate seat 4 can be gradually increased at one end of the adjusting bolt 12, and the pressing plate will be pressed against the mold 1. The length of the adjusting bolt 12 is greater than the sum of the maximum gap value between the pressing plate 3 and the pressing plate seat 4 after the pressing plate 3 is rotated and the thickness of the pressing plate 3. In other words, the length of the adjusting bolt 12 is long enough to support the maximum distance adjustment between the pressing plate 3 and the pressing plate 3 at one end where the adjusting bolt 12 is located, so as to meet its maximum functional role.

[0030] Preferably, there is a gap between the lower end surface of the pressing plate 3 and the pressing plate seat 4, and an abutting portion 14 protruding downward is provided on one end of the pressing plate 3 away from the adjusting device, and the abutting portion 14 abuts against the mold 1. Since the abutting portion 14 protrudes toward one end of the pressing plate seat 4, it will first contact the mold 1, thereby ensuring the movable distance between the pressing plate 3 and the pressing plate seat 4 to the greatest extent.

[0031] Preferably, it further comprises a rotating shaft 8, the pressing plate seat 4 has a relatively arranged mounting ear 5, the mounting ear 5 has a mounting hole 6, the pressing plate 3 has a rotating shaft hole 7 corresponding to the mounting hole 6, the rotating shaft 8 is installed in the mounting hole 6 and the rotating shaft hole 7, and the pressing plate 3 is installed on the pressing plate seat 4 by the coordinated rotation of the rotating shaft 8, the mounting hole 6 and the rotating shaft hole 7. At this time, the pressing plate 3 rotates like a seesaw structure, and can be adjusted by rotation when different molds 1 need to be pressed.

[0032] like Figure 4As shown, it also includes an anti-skid groove 9 extending radially along the rotating shaft 8, and an anti-skid bolt 10 corresponding to the anti-skid groove 9. The pressing plate 3 is provided with an anti-skid bolt hole 11 connected to the rotating shaft hole 7. The anti-skid bolt 10 is installed in the anti-skid bolt hole 11 and its end is located in the anti-skid groove 9. Since the rotating shaft 8 is rotatably installed in the rotating shaft hole 7 and the mounting hole 6, vibration will be generated during mechanical processing. In order to prevent the rotating shaft 8 from sliding out of the rotating shaft hole 7 and the mounting hole 6, a device for limiting its sliding out is required. The anti-skid groove 9 is an arc-shaped groove extending radially along the rotating shaft 8, which does not affect the rotation of the rotating shaft 8 in the rotating shaft hole 7. After the anti-skid bolt 10 is installed in the anti-skid bolt hole 11 on the pressing plate 3, its end is also inserted into the anti-skid groove 9. The pressing plate 3 is also limited between the two mounting ears 5, so the rotating shaft 8 will not slide out of the mounting hole 6.

[0033] Working principle: When in use, first install the pressure plate seat 4 on the mold placement plate 2 through the cooperation of the T-slot 15 and the T-mounting block 16, then rotate the pressure plate 3, place the mold 1 on the mold placement plate 2, and rotate the pressure plate 3 again so that one end of it abuts against the mold 1. At this time, screw the adjusting bolt 12, and under its action, the distance between the other end of the pressure plate 3 and the pressure plate seat 4 is gradually increased, which means that the pressure plate 3 is gradually pressed against the mold 1; if the mold 1 needs to be replaced, loosen the adjusting bolt 12, the pressure plate 3 can be rotated, and the mold 1 can be removed from the mold placement plate 2.
