Description

Technical Field

[0001] This utility model belongs to the field of mold technology, and in particular relates to a novel cam-type inclined plane unlocking structure. Background Technology

[0002] Molds are tools used in industrial production to shape objects. They are mainly used to process the shape of objects by changing the physical state of materials. They are usually made of metal or non-metal materials and have specific shapes and structures. Molds are widely used in many fields such as automobiles, electronics, home appliances, and aerospace. They are key to achieving efficient and low-cost mass production.

[0003] However, existing technologies have some problems: current molds use a fixed structure during the molding process. This is to lock the mold in place to prevent shaking and maintain the quality of the mold processing, and to facilitate the replacement of the mold for different products. However, the existing fixed structure requires manual operation by workers. Therefore, during installation, workers need to repeatedly adjust the fixed structure, which is very troublesome and may pose a risk to the personal safety of workers. Therefore, we propose a new cam-type inclined plane unlocking structure. Utility Model Content

[0004] To address the problems existing in the prior art, the purpose of this utility model is to provide a novel cam-type inclined plane unlocking structure. Through the cam follower, the positioning and guiding effect is achieved, effectively avoiding the impact of the fixing components on the second mold base during descent, and preventing the second mold base from shaking or shifting. This improves the accuracy, stability, and installation speed during installation.

[0005] This utility model is implemented as follows: the novel cam-type inclined plane unlocking structure includes:

[0006] The clamping mechanism is located above the base, and a first mold base and a second mold base are provided below the clamping mechanism. A positioning pin is provided on the upper surface of the base, and the second mold base is engaged with the positioning pin.

[0007] The fixing components are provided in multiple sets and are disposed on the upper surface of the base. A fixing surface is provided at the corner of the second mold base. The fixing components are fitted with the fixing surface to fix the second mold base.

[0008] A cam follower is disposed on one side of the clamping mechanism and is arranged vertically to correspond with the fixing component to drive the movement of the fixing component.

[0009] Optionally, the fixing component includes a limiting block and a fixing seat. The fixing seat is disposed on the upper surface of the base, a guide rod is disposed on one side of the fixing seat, the limiting block is disposed on the outer surface of the guide rod, and the limiting block is in contact with the fixing surface.

[0010] Optionally, a return spring is provided on the outer surface of the guide rod, the return spring is located between the fixed seat and the limiting block, and a rotating shaft is provided at the lower end of the limiting block, the rotating shaft being rotatably mounted on the upper surface of the base.

[0011] Optionally, a connecting block is provided on one side of the limiting block, and the upper and lower inclined surfaces of the connecting block are respectively arranged to correspond to the cam follower.

[0012] Optionally, a connecting rod is provided on one side of the cam follower, and the connecting rod is located on one side of the clamping mechanism.

[0013] Optionally, the clamping mechanism includes a top plate, with movable frames at both ends of the lower surface of the top plate, a protrusion on one side of the lower end of the movable frame, and grooves on both sides of the first mold base and the second mold base, with the protrusion engaging with the groove.

[0025] To further understand the utility model content, features and effects of this utility model, the following embodiments are provided, and detailed descriptions are given in conjunction with the accompanying drawings.

[0026] like Figures 1 to 5 As shown, the novel cam-type inclined plane unlocking structure provided in this embodiment of the present invention includes: a clamping mechanism 1 and a base 3. The clamping mechanism 1 is located above the base 3, and a first mold base 4 and a second mold base 5 are arranged below the clamping mechanism 1. A positioning pin 10 is arranged on the upper surface of the base 3, and the second mold base 5 is engaged with the positioning pin 10; a fixing component 6, which is provided in multiple sets and is arranged on the upper surface of the base 3. A fixing surface 8 is provided at the corner of the second mold base 5, and the fixing component 6 is arranged correspondingly to the fixing surface 8 for fixing the second mold base 5; and a cam follower 2, which is arranged on one side of the clamping mechanism 1 and is arranged correspondingly to the fixing component 6 for driving the fixing component 6 to move.

[0027] like Figures 1 to 4 As shown, the first mold base 4 is located above the second mold base 5. When the clamping mechanism 1 clamps the second mold base 5, it will also drive the first mold base 4 to move. In this way, during use, the clamping mechanism 1 connects the second mold base 5 with the positioning pin 10 to place the second mold base 5 on the upper surface of the base 3 so that the following processing operations can be carried out.

[0028] Specifically, when the second mold base 5 is lowered, the cam follower 2 on one side of the clamping mechanism 1 causes the locking block of the fixing component 6 to extend outward, moving away from the second mold base 5. This prevents the second mold base 5 from being affected during its normal descent, causing it to wobble and shift, thus preventing it from engaging with the positioning pin 10. This achieves a positioning and guiding effect, effectively preventing wobbling and shifting during descent, improving the accuracy, stability, and speed of installation. After engagement, the clamping mechanism 1 drives the cam follower 2 to slide to one side, moving away from the fixing component 6. This causes the fixing component 6 to automatically reset and lock onto the fixing surface 8 at the corner of the second mold base 5, thereby limiting and fixing the second mold base 5. This achieves automatic fixing of the second mold base 5, improving ease of use. When the clamping mechanism 1 releases its clamping effect on the second mold base 5, it will not lift the second mold base 5 while it is rising. Then, the clamping mechanism 1 can be connected to the first mold base 4, which will drive the first mold base 4 to slide up and down to complete the processing operation. Conversely, when disassembly is required, the clamping mechanism 1 will clamp the second mold base 5 again, so that the cam follower 2 returns to the bottom of the locking block of the fixing component 6. At this time, the clamping mechanism 1 is pulled upward, and the cam follower 2 will rise accordingly to lift the locking block of the fixing component 6. The locking block extends outward and releases its contact with the fixing surface 8. Then, the second mold base 5 will slide upward with the clamping mechanism 1 to remove the second mold base 5 from the base 3, thereby achieving the effect of convenient disassembly and assembly of the second mold base 5 and improving maintenance convenience.

[0029] Furthermore, the fixing component 6 includes a limiting block 601 and a fixing seat 603. The fixing seat 603 is disposed on the upper surface of the base 3. A guide rod 604 is disposed on one side of the fixing seat 603. The limiting block 601 is disposed on the outer surface of the guide rod 604. The limiting block 601 is in contact with the fixing surface 8.

[0030] Specifically, such as Figures 2 to 3 As shown, the lower surface of the protruding part on one side of the limiting block 601 is a surface for contacting the fixing surface 8. Thus, when the lower surface of the protruding part is in contact with the fixing surface 8 during use, the second mold base 5 is fixed. Conversely, when the protruding part moves away from the fixing surface 8, the second mold base 5 is released from fixation. This allows the operator to easily know whether the second mold base 5 has been fixed.

[0031] It should be noted that the length of the protrusion is set according to the equipment, mainly to avoid affecting normal disassembly during disassembly and to ensure better fit with the fixing surface 8 during installation.

[0032] Furthermore, a return spring 606 is provided on the outer surface of the guide rod 604. The return spring 606 is located between the fixed base 603 and the limiting block 601. A rotating shaft 605 is provided at the lower end of the limiting block 601. The rotating shaft 605 is rotatably mounted on the upper surface of the base 3.

[0033] Specifically, such as Figure 5 As shown, the limiting block 601 can rotate on one side of the fixed base 603 via the guide rod 604 and the rotating shaft 605, thereby improving the flexibility of the limiting block 601. Through the return spring 606 provided on the outer surface of the guide rod 604, the limit block 601 can automatically reset after being rotated under force and no longer under force, thus achieving the effect of quick limiting after convenient adjustment and improving applicability.

[0034] Furthermore, a connecting block 602 is provided on one side of the limiting block 601, and the upper and lower inclined surfaces of the connecting block 602 are respectively arranged to correspond to the cam follower 2.

[0035] Specifically, such as Figure 5 As shown, the connecting block 602 and the limiting block 601 are fixed together, but the connecting block 602 and the cam follower 2 are arranged vertically in correspondence. During installation, the cam follower 2 descends with the clamping mechanism 1 and comes into contact with the connecting block 602. As the cam follower 2 continues to descend, the connecting block 602 will tilt to one end, thereby changing the position of the limiting block 601, thus achieving the effect of facilitating the driving of the limiting block 601.

[0036] It should be noted that the limiting block 601 has a protrusion at one end forming two inclined surfaces. During installation, the cam follower 2 contacts the upper inclined surface during its descent to drive the limiting block 601 to move. After the second mold base 5 is placed on the upper surface of the base 3, the cam follower 2 continues to move. When it moves to the position of the lower inclined surface, the limiting block 601 will automatically reset through the return spring 606 to fix the second mold base 5. During disassembly, the cam follower 2 rises and contacts the lower inclined surface. The connecting block 602 tilts to one end, contacting the limiting block 601 to achieve the limiting effect, allowing the second mold base 5 to move.

[0037] Furthermore, a connecting rod 7 is provided on one side of the cam follower 2, and the connecting rod 7 is located on one side of the clamping mechanism 1;

[0038] Specifically, such as Figure 1 and Figure 2 As shown, the connecting rod 7 is used to support the cam follower 2, so that the cam follower 2 can operate normally and improve the stability of the cam follower 2.

[0039] Furthermore, the clamping mechanism 1 includes a top plate 101, with movable frames 102 provided at both ends of the lower surface of the top plate 101, and a protrusion 103 provided on one side of the lower end of the movable frame 102. Grooves 9 are provided on both sides of the first mold base 4 and the second mold base 5, and the protrusion 103 engages with the groove 9.

[0040] Specifically, such as Figures 1 to 4 As shown, the design of grooves 9 on both sides of the first mold base 4 and the second mold base 5 makes it possible to move the first mold base 4 or the second mold base 5 during use. Simply insert the protrusion 103 on one side of the movable frame 102 into the corresponding groove 9 to connect with it, thereby moving the corresponding first mold base 4 or the second mold base 5, thus improving the ease of use.

[0041] Furthermore, guide rails 104 are provided at both ends of the lower surface of the top plate 101, and guide plate 105 is provided on the upper surface of the movable frame 102. The guide plate 105 is slidably installed inside the guide rails 104.

[0042] Specifically, such as Figure 2 As shown, the movable frame 102 can slide horizontally below the top plate 101 by sliding the guide plate 105 within the guide rail 104, thereby improving the flexibility of the movable frame 102 and facilitating the clamping and disassembly of the first mold base 4 and the second mold base 5, thus improving its practicality.

[0043] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
