Description

Technical Field

[0001] This utility model relates to the field of EVA cold and hot foaming molding machine mold technology, and in particular to an adjustable EVA cold and hot foaming molding machine mold auxiliary support device. Background Technology

[0002] EVA hot and cold foaming molding machines are core equipment for producing EVA foamed products (such as insoles, packaging cushioning components, and sports equipment accessories). As a key component in the molding process, the mold requires an auxiliary support device for precise positioning, stable support, and convenient loading and unloading. In EVA hot and cold foaming production, molds come in various specifications (such as different sizes and cavity structures), and the molding process must withstand high temperatures and pressures, placing extremely high demands on the adaptability, stability, and protective properties of the auxiliary support device. However, existing auxiliary support devices for EVA hot and cold foaming molding machines have many technical limitations, severely restricting production efficiency and product quality.

[0003] Existing auxiliary lifting devices are mostly fixed structures with fixed lifting platform dimensions and positioning methods. For molds of different sizes, the corresponding lifting device needs to be replaced, which requires machine downtime and multiple sets of devices need to be stocked, increasing equipment procurement and storage costs. The mold cavity structure varies greatly, and the existing positioning components cannot be flexibly adjusted, which can easily lead to mold positioning deviation. After molding, EVA products will have flash and dimensional deviations, requiring post-processing trimming, which increases process costs. Therefore, we have proposed an adjustable auxiliary lifting device for EVA cold and hot foaming molding machines. Utility Model Content

Rotating the adjusting screw 21 causes the longitudinal slider 23 to slide along the longitudinal guide rail 24, adjusting the longitudinal position of the lifting device. Rotating the transverse adjusting handwheel 32 drives the transverse adjusting screw 31 to rotate, causing the transverse slider 33 to slide along the transverse guide rail 34. The locking bolt 71 can lock the longitudinal adjusting handwheel 22 and the transverse adjusting handwheel 32 to prevent movement after adjustment. It is compatible with EVA hot and cold foaming molds of different sizes, eliminating the need to replace the lifting device and reducing equipment costs.

This adapts to EVA hot and cold foaming molds of different sizes, eliminating the need to replace the lifting device and reducing equipment costs.

[0032] The drive control and positioning components simplify the operation process: the drive motor 71 can be controlled by the start / stop button 73, which can quickly complete the longitudinal and lateral position adjustment without the need for manual rotation of multiple handwheels; the positioning block 51 of the mold positioning component 5 can be flexibly adjusted in position by the positioning bolt 52 to adapt to molds with different cavity structures, and the positioning rubber pad 53 prevents the mold from bumping during positioning; the distance sensor 91 detects the distance between the mold and the molding machine mold frame in real time, and the data is displayed intuitively on the display screen 92, eliminating the need for manual measurement, reducing labor intensity, and improving adjustment accuracy;

[0034] Multiple protective structures extend the life of molds and devices: positioning rubber pads 53 prevent surface scratches during mold positioning, buffer pads 62 reduce the impact of gravity when placing the mold and protect the accuracy of the mold cavity; the reinforcing ribs 42 of the mold lifting platform 4 enhance the structural strength of the lifting panel 41 and can withstand the weight of heavy molds.

If a positioning deviation occurs, it can be detected and adjusted in time through the display screen 92 to avoid batch rework; no need to stop the machine for manual measurement, reducing detection time and improving production continuity; at the same time, the motor controller 72 can preset the adjustment parameters of different molds, and directly call the parameters when changing molds, shortening the mold change time and further improving production efficiency.
