Description

Technical Field

[0001] This utility model relates to heavy mold transportation equipment, specifically a heavy mold transport and installation trolley device, which is particularly suitable for the automated transport and precise installation of heavy molds for large equipment such as injection molding machines and die casting machines. Background Technology

[0002] Currently, the common method for installing heavy-duty molds is to lay circular rods on the equipment template and manually push the mold for positioning. This method has drawbacks: manual pushing is time-consuming and labor-intensive, and it is impossible to control multiple circular rods simultaneously; the rolling stability of the circular rods is poor, which can easily lead to mold displacement or even overturning; the positioning accuracy is low, requiring repeated adjustments, which poses risks of mechanical collisions and personal injury, and can easily cause mechanical damage and safety accidents.

[0003] Existing technologies lack integrated, bidirectionally adjustable mold transport devices, and a safe and efficient solution is urgently needed. Summary of the Invention

[0004] This utility model addresses the above-mentioned technical problems by providing a heavy-duty mold transport and installation trolley device, which overcomes the shortcomings of existing heavy-duty mold transport and installation methods. It has a compact structure, saves time and effort in positioning, and is highly accurate, safe, and reliable, significantly improving the efficiency of mold installation and replacement.

[0005] To achieve the above objectives, the technical solution of this utility model is as follows:

[0006] A heavy-duty mold transport and installation trolley device includes a trolley platform, a guide seat, and a mold transfer frame;

[0007] The trolley platform is located outside the main unit's locking area;

[0008] The guide seats are located on both sides of the trolley platform to provide longitudinal movement guidance;

[0009] The mold transfer frame is disposed between the guide seats on the trolley platform;

[0010] The mold transfer frame is equipped with several longitudinal and transverse moving rollers. The longitudinal moving rollers allow the mold to move longitudinally on the trolley platform. The transverse moving rollers carry the mold and allow the mold to move laterally on the mold transfer frame via the transverse moving rollers.

[0011] The mold-moving frame of this heavy-duty mold transport and installation trolley enters the main machine's mold-locking area via a longitudinal moving roller, and achieves precise alignment between the mold and the mold-locking device based on a lateral moving roller. This trolley device has a compact structure, and the mold positioning is adjustable both longitudinally and laterally, saving time and effort. Fine-tuning can be performed without power during adjustment, resulting in low manufacturing costs. The mold-moving frame drives the mold longitudinally along the guide seat, preventing mold tipping. It offers good stability during movement, and lateral adjustment of the mold requires only fine-tuning, eliminating the risk of accidents.

[0012] In a further optimized design, longitudinal and transverse moving rollers are arranged side-by-side on both sides of the mold transfer frame, with the longitudinal and transverse moving rollers alternating in arrangement. The double rows of longitudinal and transverse moving rollers ensure uniform and stable load-bearing and mold movement.

[0013] A further optimized design includes a longitudinally moving roller comprising a caster axle, a caster, and a cylindrical roller bearing. The caster axle is mounted on the mold transfer frame, and the caster is connected to the caster axle via the cylindrical roller bearing. The cylindrical roller bearing ensures stability during heavy-duty longitudinal movement.

[0014] In a further optimized design, the lateral moving roller includes a roller shaft, a roller, a roller seat, and a double-row needle roller bearing. The roller seat is connected to the mold transfer frame, the roller shaft is mounted on the roller seat, and the roller is connected to the roller shaft via the double-row needle roller bearing. The use of a double-row needle roller bearing optimizes the lateral sliding efficiency of the mold.

[0015] This utility model has the following technical advantages compared with the prior art:

[0016] 1. The heavy-duty mold transport and installation trolley has a compact structure, reducing the space required for installation;

[0017] 2. The mold's longitudinal and transverse bidirectional micro-adjustment accuracy reaches ±1mm, improving mold positioning efficiency by more than 50%;

[0018] 3. The fully mechanical load-bearing mold and longitudinal moving guide seat are designed to prevent the mold from tipping over and eliminate safety accidents;

[0019] 4. The mold can be finely adjusted without power within the main machine's locking area, resulting in low manufacturing costs. Attached Figure Description

Detailed Implementation

[0027] The present invention will now be described in further detail with reference to the embodiments shown in the accompanying drawings.

[0028] like Figures 1 to 6 The figure shown is a specific embodiment of the heavy-duty mold transport and installation trolley device of this utility model and its application diagram.

[0029] like Figure 1 and Figure 2 As shown, the heavy-duty mold transport and installation trolley device of this embodiment includes a trolley platform 10, a guide seat 30, and a mold transfer frame 20;

[0030] The trolley platform 10 is located outside the main unit's molding area. Figure 5 (as shown)

[0031] The guide seats 30 are arranged on both sides of the trolley platform 10 to provide longitudinal movement guidance;

[0032] The mold transfer frame 20 is positioned between the guide seats 30 on the trolley platform 10;

[0033] The mold transfer frame 20 is equipped with several longitudinal moving rollers 40 and transverse moving rollers 50. The longitudinal moving rollers 40 move longitudinally on the trolley platform 10; the transverse moving rollers 50 carry the mold and move laterally on the mold transfer frame 20 via the transverse moving rollers 50.

[0034] The mold-moving frame 20 of the heavy-duty mold transport and installation trolley enters the main machine's mold-locking area via the longitudinal moving roller 40, and achieves precise alignment between the mold and the mold-locking device based on the transverse moving roller 50. This trolley device has a compact structure, and the mold positioning is adjustable both longitudinally and transversely, saving time and effort. Fine-tuning can be achieved without power during adjustment, and the mechanism has low manufacturing costs. The mold-moving frame 20 drives the mold to move longitudinally along the guide seat 30, preventing mold tipping. It offers good stability during movement, and transverse adjustments of the mold require only fine-tuning, eliminating the risk of accidents.

[0035] like Figure 1 and Figure 2 As shown, longitudinal moving rollers 40 and transverse moving rollers 50 are arranged side by side on both sides of the mold transfer frame 20, with the longitudinal moving rollers 40 and transverse moving rollers 50 alternating. The double rows of longitudinal moving rollers 40 and transverse moving rollers 50 ensure uniform and stable load-bearing and mold movement. The figure shows four longitudinal moving rollers 40 on each side and three transverse moving rollers 50 on each side.

[0036] like Figure 2 and Figure 3 As shown, each longitudinally moving roller 40 includes a caster axle 41, a caster 42, two cylindrical roller bearings 43, a first baffle 44, and a bearing retaining ring 45. The caster axle 41 is mounted on the mold transfer frame 20, and the caster 42 is connected to the caster axle 41 through the two cylindrical roller bearings 43. The first baffle 44 is located at the end of the caster axle 41, and a bearing retaining ring 45 is provided between the two cylindrical roller bearings 43. The cylindrical roller bearings 43 are provided to ensure the stability of longitudinal heavy-load movement.

[0037] like Figure 2 and Figure 4 As shown, the lateral moving roller 50 includes a roller shaft 51, a roller 52, a roller seat 53, a double-row needle roller bearing 54, and a second baffle 55. The roller seat 53 is connected to the mold transfer frame 20, the roller shaft 51 is mounted on the roller seat 53, the roller 52 is connected to the roller shaft 51 via the double-row needle roller bearing 54, and the second baffle 55 is located at the end of the roller shaft 51. The double-row needle roller bearing 54 optimizes the lateral sliding efficiency of the mold.

[0038] like Figure 5 and Figure 6 As shown, the working process of this heavy-duty mold transport and installation trolley device is as follows:

[0039] The mold transfer frame 20 can enter and exit the mold locking area of ​​the main mold locking device along the trolley platform 10 via the longitudinal moving roller 40. The guide seat 30 plays a guiding role. If there is a positional deviation after the mold transfer frame 20 is loaded into the mold locking area, it can be finely adjusted by the transverse moving roller 50 and the longitudinal moving roller 40.

[0040] After the mold position is properly adjusted, the mold locking device uses hydraulic pressure to drive the lower mold plate B2 to move the mold transfer frame 20 and the mold upward together towards the upper mold plate B1. After the position is aligned, the upper mold A1 is fixed on the upper mold plate B1. Then the lower mold plate B2 descends, moving the mold transfer frame 20 out of the mold locking area. Subsequently, the lower mold plate B2 rises again to approach the mold, fixing the lower mold A2 on the lower mold plate B2. The locking screws between the upper mold A1 and the lower mold A2 are loosened, separating the upper mold A1 and the lower mold A2, completing the mold installation and fixing work.

[0041] This heavy-duty mold transport and installation trolley device overcomes the shortcomings of traditional heavy-duty mold transport and installation methods; it has a compact structure, saves time and effort in positioning, and is highly accurate, safe and reliable; it significantly improves the efficiency of mold installation and replacement.

[0042] In summary, as described in the specification and figures, this utility model has been manufactured into actual samples and subjected to multiple use tests. The test results demonstrate that this utility model achieves its intended purpose, and its practicality is beyond doubt. The embodiments described above are merely for illustrative purposes and are not intended to limit the scope of this utility model.
