A sensing structure that reduces surface clearance
By installing a combination structure of a detection rod and a sensor on the mold, the spatial limitation problem of surface sensing on small product molds is solved, realizing the sensing function of small products. Furthermore, the lubrication of the lubricating oil reduces friction and improves the structural strength.

AI Technical Summary
Technical Problem
Existing product sensing structures have large sensor sizes, which requires large mounting slots to be opened on the mold surface, making it difficult to achieve surface sensing on small product molds.
Method used
The sensor structure reduces the clearance between the mold surface and the sensor rod. The sensor rod is installed by opening a small through hole in the mold. The sensor rod, push plate, extension column and sensor are combined to realize the installation of the sensor rod. The gap between the sensor rod and the mold is lubricated by lubricating oil.
Benefits of technology
It reduces the space occupied by the mold surface, is suitable for small products, facilitates lubrication, avoids product scratches, and improves structural strength.

Abstract
This invention provides a sensing structure that reduces space requirements on the mold surface, comprising a mounting plate, a push plate, a detection rod, an extension column, a partition plate, a linear spring, a base plate, a sensor, and a sleeve. The sleeve is fixed to the lower side of the mounting plate, and the mounting plate is fixed to the back of the mold. The push plate is slidably mounted inside the sleeve, with a detection rod fixed to its upper side, which slides through the mold. A partition plate is provided on the lower side of the push plate, fixed to the inner wall of the sleeve, and a linear spring is provided between the partition plate and the push plate. An extension column is fixed to the lower side of the push plate, with a base plate fixed to its lower end, positioned below the partition plate. A sensor is fixed to the lower end of the sleeve, with the sensor's detection end facing the base plate, and the sensor is electrically connected to an external production computer via a data cable. This design minimizes the space occupied by the mold surface, thus facilitating the use of smaller products.
