Description

Technical Field

[0001] The utility model relates to the technical field of foaming clamps, in particular to a sliding plate type foaming clamp locking mechanism. Background Art

[0002] Refrigerator foam parts are crucial core components in refrigerator manufacturing. They are mainly formed by polyurethane foam materials through a foaming process. Their functions run through many key links of the refrigerator, such as insulation, structure, and energy saving.

[0003] During the production process of refrigerator foam parts, the product shell is placed against the mold, and then foaming liquid is injected between the two to foam. The existing technology uses the product shell to abut the mold from bottom to top, and the rising mechanism pushes the product shell up to abut the mold. The rising mechanism uses a threaded screw, hydraulic mechanism or cylinder.

[0004] During the polyurethane foaming process, tension will be generated, which will exert downward pressure on the movable frame. As the equipment ages, the foaming tension generated by the foaming will cause the lifting mechanism to have a stroke deviation, resulting in a small dynamic error between the product shell and the mold, which will change or even reduce the product production quality. Therefore, we need to provide a slide-type foaming clamp locking mechanism to support the movable mold. Utility Model Content

[0005] The purpose of the utility model is to provide a slide plate type foaming clamp locking mechanism to solve the above-mentioned deficiencies in the prior art.

[0010] Furthermore, the length of the clamping long strip is twice that of the clamping short strip, and one side of the clamping long strip and the one side of the clamping short strip are on the same reference plane.

[0011] Furthermore, the driving assembly includes a worm gear screw lift, which is installed on a mounting frame, and a movable end of the worm gear screw lift is rotatably connected to one end of a connecting plate.

[0012] Furthermore, a motor is installed on the top of the mounting frame, and a first gear is fixedly sleeved on the outside of the output end of the motor. A second gear is fixedly sleeved on the outside of the worm extending out of the housing on the worm gear screw elevator, and a chain belt is externally meshed with the first gear and the second gear.

[0013] Furthermore, a guide plate is fixedly connected to the mounting frame, a sliding groove is provided on the guide plate, a round rod is fixedly connected to the side surface of the connecting plate, and the round rod is slidably arranged in the sliding groove.

[0014] In the above technical solution, the slide plate type foaming clamp locking mechanism provided by the present invention has the following beneficial effects:

[0026] To make the purpose, technical solutions, and advantages of the embodiments of the present disclosure more clear, the technical solutions of the embodiments of the present disclosure will be clearly and completely described below in conjunction with the accompanying drawings of the embodiments of the present disclosure. Obviously, the described embodiments are part of the embodiments of the present disclosure, not all of the embodiments. Based on the described embodiments of the present disclosure, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present disclosure.

[0027] See also Figure 1-Figure 5A sliding plate type foaming clamp locking mechanism comprises: a mounting frame 1, a mold base 3 and a movable frame 2 slidingly arranged below the mold base 3 are fixedly mounted on the mounting frame 1, two symmetrically arranged guide rods are fixedly connected to the mounting frame 1, and the movable frame 2 is slidably arranged on the two guide rods. The movable frame 2 is pushed by a lifting mechanism, and the lifting mechanism is a threaded screw, a hydraulic mechanism or a cylinder, which can be purchased on the market; two hoisting assemblies are fixedly connected to the bottom of the mounting frame 1, and a locking assembly 4 is slidably arranged in the two hoisting assemblies, and a clamping assembly that can be clamped on the locking assembly 4 is fixedly connected to the top of the movable frame 2. The locking assembly 4 is driven by the driving assembly to move in the horizontal direction to realize the clamping assembly being clamped in the locking assembly. On the component 4, the locking component 4 includes a connecting plate 41, which is slidably set in the two lifting components. The lifting component includes two symmetrically arranged first L-shaped limit blocks 11, and the two lifting components include four first L-shaped limit blocks 11. Both sides of the connecting plate 41 are fixedly connected with a snap-in long strip 42 that is slidably set in the first L-shaped limit block 11. The snap-in component includes two symmetrically arranged second L-shaped limit blocks 21, and the two snap-in components include four second L-shaped limit blocks 21. Both sides of the connecting plate 41 are fixedly connected with a snap-in short strip 43 that is slidably set in the second L-shaped limit block 21. The first L-shaped limit block 11 and the second L-shaped limit block 21 are both L-shaped blocks.

[0028] Specifically, the product shell is placed in the mobile rack 2, and the mold is installed on the bottom of the mold base 3. The mobile rack 2 is pushed up by the lifting mechanism to drive the product shell to move up, so that the product shell is against the mold, and the foaming liquid is injected through the injection hole reserved on the mold for foaming. The utility model is pushed by the driving assembly through the locking assembly 4, so that the locking assembly 4 slides in the hoisting assembly and slides into the clamping assembly, so that the clamping assembly is clamped on the locking assembly 4, and then the mobile rack 2 is hoisted on the mounting rack 1, thereby offsetting the tension generated during the foaming process of the foaming material polyurethane, optimizing the state when the product shell and the mold are abutted, making the product quality consistent, and extending the equipment maintenance cycle, reducing the equipment maintenance cost.

[0029] Furthermore, the length of the clamping strip 42 is twice that of the clamping short strip 43, and the clamping strip 42 and one side of the clamping short strip 43 are on the same reference plane. In the initial position, when the clamping strip 42 is slidably set in the first L-shaped limit block 11, half of the clamping strip 42 is located outside the first L-shaped limit block 11. This ensures that when the lifting mechanism pushes the movable frame 2 to rise, the second L-shaped limit block 21 will not collide with the clamping short strip 43, but the second L-shaped limit block 21 will rise to one side of the clamping short strip 43.

[0030] Specifically, refer to Figures 1 to 5First, the movable rack 2 is pushed by the lifting mechanism to achieve the contact between the mold installed in the mold base 3 and the product shell placed in the movable rack 2. Then, the driving component drives the connecting plate 41 to move to the right, so that the four clamping short strips 43 provided on the connecting plate 41 slide into the corresponding second L-shaped limit blocks 21, so that the movable rack 2 is hoisted on the connecting plate 41, and then overcomes the tension generated during the foaming process of the foaming material.

[0031] Furthermore, the driving assembly includes a worm gear screw lift 7, which is installed on the mounting frame 1. The movable end of the worm gear screw lift 7 is rotatably connected to one end of the connecting plate 41. The movable end of the worm gear screw lift 7 is rotatably connected to the connecting plate 41, so that a certain offset is allowed between the connecting plate 41 and the movable end of the worm gear screw lift 7 in the vertical direction, thereby avoiding a rigid connection between the connecting plate 41 and the movable end of the worm gear screw lift 7. The worm gear screw lift 7 is a worm gear screw lift currently sold on the market. Its internal structure and working principle are common knowledge well known to those skilled in the art, and no further explanation is given here.

[0032] Furthermore, a motor 5 is installed on the top of the mounting frame 1, and a first gear 61 is fixedly sleeved on the outside of the output end of the motor 5, and a second gear 63 is fixedly sleeved on the outside of the worm extending out of the housing on the worm gear screw lift 7. The first gear 61 and the second gear 63 are externally meshed with a chain belt 62. The motor 5 is a servo motor, and the first gear 61 is driven to rotate by the motor 5, and then the chain belt 62 drives the second gear 63 to rotate, so that the worm in the worm gear screw lift 7 is driven, and then the worm in the worm gear screw lift 7 drives the worm wheel to rotate, and then drives the internal screw to move in the direction of the worm wheel axis, so that the movable end of the worm gear screw lift 7 drives the connecting plate 41 to move in the left and right directions, thereby realizing the locking or unlocking of the second L-shaped limit block 21 by the short strip 43.

[0033] Furthermore, a guide plate 12 is fixedly connected to the mounting frame 1, a slide groove 121 is provided on the guide plate 12, a round rod 411 is fixedly connected to the side of the connecting plate 41, and the round rod 411 is slidably set in the slide groove 121. By adding the structure that the round rod 411 is slidably set in the slide groove 121, the stability of the connecting plate 41 sliding in the first L-shaped limit block 11 is enhanced.

[0034] In this utility model, reference is made to Figures 1 to 5First, the movable frame 2 is pushed by the lifting mechanism to achieve the contact between the mold set in the mold base 3 and the product shell placed in the movable frame 2. At this time, the second L-shaped limit block 21 is located on the right side of the clamping short strip 43. Then, the motor 5 drives the worm gear elevator 7 to drive the connecting plate 41 to move to the right, so that the four clamping short strips 43 set on the connecting plate 41 slide into the corresponding second L-shaped limit blocks 21, so that the movable frame 2 is hoisted on the connecting plate 41, and then overcomes the tension generated during the foaming process of the foaming material.

[0035] The above description is merely illustrative of certain exemplary embodiments of the present invention. It goes without saying that those skilled in the art will be able to modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and description are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
