Description

Technical Field

[0001] The utility model relates to the technical field of mold replacement, in particular to a quick mold-changing vehicle which is convenient for replacing molds. Background Art

[0002] Existing bending, welding, hot pressing and other equipment all require the use of molds. Usually the molds are detachably installed on the equipment. When the equipment produces different models of products, or when the mold needs maintenance after long-term use, the mold needs to be replaced.

[0003] Since the mold is large and heavy, if it is directly replaced by manual handling, it will not only be time-consuming and labor-intensive, but also inefficient and prone to safety hazards. Therefore, a mold changing trolley is usually used in the process of replacing the mold.

[0004] For example, the prior art CN201210481535.6 discloses a mold replacement vehicle, which includes a vehicle frame, a lifting seat, a lifting device, and a positioning device. However, the following problems exist during the mold replacement process:

[0005] 1. In the prior art, the mold is automatically pulled out or pushed into the equipment through a push-pull device. If a worker accidentally touches a switch and activates the push-pull device during the movement, a safety accident is likely to occur.

[0006] 2. The prior art uses components such as a winch, a pneumatic claw, a speed reducer, and a positioning cylinder, which require not only power supply but also air supply, making the movement very inconvenient.

[0007] 3. In the prior art, the lifting seat and the lifting device adopt a cantilever structure. Since the mold is heavy, the connection between the lifting seat and the lifting device is easily deformed, resulting in a short service life. Utility Model Content

[0008] The utility model aims to overcome the deficiencies of the prior art and provide a quick-change mold vehicle which is convenient for replacing molds.

[0031] The present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0032] Attachment Figure 1-6The quick mold-changing vehicle for convenient mold replacement according to the present invention comprises a vehicle frame 1, a traveling wheel 2 provided at the bottom of the vehicle frame 1, a lifting frame 3 provided above the vehicle frame 1, a lifting mechanism 4 provided on the vehicle frame 1 for driving the lifting frame 3 to move upward and downward, and a supporting sliding assembly 5 and a limiting assembly 6 respectively provided at the top of the lifting frame 3;

[0033] The frame 1 and the lifting frame 3 are both square and welded from profiles;

[0034] The support sliding assembly 5 includes two parallel support rods 51 placed along the direction of loading and unloading of the mold, and a plurality of bull's eye balls 52 spaced apart on the support rods 51;

[0035] The limiting assembly 6 includes limiting side plates 61 respectively provided on both sides of the supporting sliding assembly 5, two fixed stops 62 fixedly provided at one end of the supporting sliding assembly 5, two movable stops 63 rotatably provided at the other end of the supporting sliding assembly 5, a driving mechanism 64 provided on one side of the fixed stops 62 for driving the movable stops 63 to rotate, and a locking mechanism 65 provided on one side of the movable stops 63 so that the driving mechanism 64 can drive the movable stops 63 to rotate only after the vehicle frame 1 is docked with the device;

[0036] The driving mechanism 64 includes a rotating shaft 641 placed parallel to the support rod 51; one end of the rotating shaft 641 is connected to the movable block 63, and the other end passes through the lifting frame 3 and is connected to the rotary handle 642;

[0037] The locking mechanism 65 includes a guide rail 651 provided on the lifting frame 3 and placed parallel to the support rod 51, a support plate 652 vertically provided on the lifting frame 3 and sleeved on the rotating shaft 641, a movable plate 653 slidably provided on the guide rail 651 and sleeved on the rotating shaft 641, a top rod 654 vertically provided on the movable plate 653 and passing through the support plate 652, a spring 655 sleeved on the top rod 654 for driving the top rod 654 to protrude outward, and a locking sleeve 656 sleeved on the rotating shaft 641; the movable block 63, the support plate 652, the locking sleeve 656 and the movable plate 653 are The plates 653 are placed in sequence along the rotating shaft 641 from the outside to the inside; the movable plate 653 is provided with a socket 657; the locking sleeve 656 is provided with a latch 658 corresponding to the socket 657; when the spring 655 drives the ejector rod 654 to protrude outward, the latch 658 is inserted into the socket 657 to restrict the rotation of the rotating shaft 641. At this time, the movable block 63 is placed vertically, higher than the support rod 51, and can play a role in limiting the mold; the top of the support plate 652, the locking sleeve 656 and the movable plate 653 are all lower than the support rod 51, and will not interfere with the mold placed on the supporting sliding assembly 5;

[0038] When the mold needs to be installed on the equipment: first transfer the mold to the quick mold change cart, and then push the quick mold change cart toward the equipment (the limiting side plates 61 on both sides and the fixed stops 62 and movable stops 63 at both ends will limit the four sides of the mold respectively), so that one end of the push rod 654 faces the equipment; when the quick mold change cart is docked with the equipment, the push rod 654 overcomes the elastic force of the spring 655 to drive the movable stop 63 to move inward, so that the socket 657 is disengaged from the latch 658 on the lock sleeve 656, and then the handle 642 is manually turned to drive the movable stop 63 to rotate through the rotating shaft 641 to cancel the limit on the mold; since the support rod 51 is provided with a bull's eye ball 52, the staff can easily push the mold onto the equipment for installation;

[0039] When the quick mold change vehicle is separated from the equipment, the push rod 654 protrudes out of the vehicle frame 1 under the elastic force of the spring 655 until the lock sleeve 656 contacts the movable plate 653; if the movable block 63 is placed vertically at this time, the pin 658 is just inserted into the socket 657, which can limit the rotation of the shaft 641 and provide high safety.

[0040] Further, if Figure 4 As shown, the outer end of the push rod 654 is provided with a threaded rubber head 659; the spring 655 is located between the rubber head 659 and the support plate 652; by providing the rubber head 659, the utility model not only has a buffering effect on the head of the push rod 654 when the frame 1 is docked with the equipment, thereby improving the service life, but also facilitates the installation of the spring 655 and the positioning of the spring 655.

[0041] Further, if Figure 1 As shown, the lifting frame 3 is provided with two quick lock buckles 7 for quick connection with the equipment at one end of the movable stopper 63. After the frame 1 is docked with the equipment, the quick lock buckles 7 can quickly fix the frame 1 and the equipment to prevent the frame 1 from separating from the equipment during the process of raising and lowering the mold, thereby avoiding safety accidents. The quick lock buckles 7 are existing technology, so their structure will not be described in detail.

[0042] Further, if Figure 1 As shown, two quick clamps 8 for fixing the mold on the supporting sliding assembly 5 are provided on one end of the fixed stop block 62 on the lifting frame 3, which effectively prevents the mold from tilting during transportation; the quick clamps 8 are existing technology, so its structure will not be described in detail.

[0043] Further, if Figure 1 As shown, a handle 9 is provided on one end of the lifting frame 3 located at the fixed stopper 62 to facilitate the movement of the quick mold change vehicle.

[0044] Further, if Figure 1As shown, the lifting mechanism 4 includes two screw jacks 41 vertically arranged on both sides of the frame 1, hand wheels 42 respectively arranged on the outside of the two screw jacks 41, a connecting shaft 43 for connecting the two screw jacks 41, and a plurality of guide pillars 44 evenly arranged between the frame 1 and the elevator; the lifting ends of the two screw jacks 41 are respectively connected to the lifting frame 3; because the two screw jacks 41 are connected by the connecting shaft 43, no matter which hand wheel 42 is rotated, the two screw jacks 41 can be synchronously driven to rotate, thereby driving the lifting frame 3 to move up and down. At the same time, because a plurality of evenly distributed guide pillars 44 are provided between the frame 1 and the elevator, they can play a guiding role during the lifting process of the lifting frame 3.

[0045] Further, if Figure 1 As shown, two horizontally placed buffer columns 10 are provided at one end of the top column of the frame, which can play a buffering role when the frame 1 is docked with the equipment to prevent the frame and the equipment from colliding.

[0046] The above are only specific application examples of the present invention and do not constitute any limitation on the scope of protection of the present invention. Any technical solution formed by equivalent transformation or equivalent replacement shall fall within the scope of protection of the present invention.
