Description

Technical Field

[0001] This invention relates to the field of mold damage detection technology, specifically to a mold damage detection device. Background Technology

[0002] In the mold industry, molds are various molds and tools used in injection molding, blow molding, extrusion, die casting, forging, smelting, stamping, and other methods to obtain the desired products. In short, a mold is a tool used to make shaped objects. This tool is composed of various parts, and different molds are composed of different parts. It mainly achieves the processing of the shape of the object by changing the physical state of the material being molded. It is known as the "mother of industry". It is a tool that makes the blank into a part with a specific shape and size under the action of external force. It is widely used in blanking, die forging, cold heading, extrusion, powder metallurgy parts pressing, pressure casting, and compression molding or injection molding of engineering plastics, rubber, ceramics and other products. Molds have a specific contour or internal cavity shape. By using the contour shape with a cutting edge, the blank can be separated according to the contour shape (blanking). The internal cavity shape can be used to give the blank a corresponding three-dimensional shape. A mold generally consists of two parts: a moving mold and a fixed mold (or a punch and a die). The two parts can be separated and joined together. When separated, the workpiece is removed, and when joined together, the blank is injected into the mold cavity to form the shape. Molds are precision tools with complex shapes. They bear the expansion force of the blank and have high requirements for structural strength, rigidity, surface hardness, surface roughness, and machining accuracy. The development level of mold production is one of the important indicators of the level of mechanical manufacturing. However, current molds need to be inspected for damage inside and outside the mold during production and use. Most inspection devices have relatively simple inspection methods and are not convenient to be adjusted according to different mold specifications, thus affecting the results of mold damage inspection. Therefore, we propose a mold damage inspection device. Summary of the Invention

[0003] The technical problem to be solved by the present invention is to overcome the existing defects and provide a mold damage detection device. The device uses an adjustable probe holder and springs to fit the detection probe to different positions inside the mold. The ultrasonic defect detector can be activated to detect the damaged areas of the mold, while the industrial camera can take pictures of the damaged areas of the mold, so as to facilitate further identification and inspection by personnel. This improves the accuracy of current damage detection and can effectively solve the problems in the background technology.

The output shaft of the main motor is connected to the middle of the top surface of the support frame. Adjusting blocks are slidably connected in the adjusting grooves on the left and right sides inside the support frame. The auxiliary motor is fixed to the side of the support frame. The output shaft of the auxiliary motor is connected to the outer end of the screw. The screw is threadedly connected to the screw hole in the middle of the adjusting block. An electric push rod is fixed to the bottom surface of the adjusting block.

[0007] The system also includes an ultrasonic defect detector and a detection probe. The ultrasonic defect detector is fixed to the front side of the support frame. The detection probe is installed inside the adjustment and detection unit. The output end of the detection probe is electrically connected to the input end of the ultrasonic defect detector. The input ends of the ultrasonic defect detector, the electric telescopic rod, the main motor, the auxiliary motor, and the electric push rod are electrically connected to the output end of the controller. The input end of the controller is electrically connected to the output end of an external power supply.

[0008] The electric telescopic rod is activated to adjust the height of the support frame, while the main motor drives the screw to rotate and adjust the position of the adjusting block. At the same time, the electric push rod is activated to adjust the position of the detection probe and industrial camera, thus making it suitable for damage detection of molds of different specifications and improving the practicality of the device.

[0009] Furthermore, the adjustment and detection unit also includes a motor, a connecting seat, a mounting bracket, a spring, and a probe holder. The top surface of the connecting seat is connected to the bottom end of the left-side electric push rod. The mounting bracket is rotatably connected inside the connecting seat.

A spring is fixedly installed in a groove inside the mounting bracket, and the bottom end of the spring is connected to one side of the top surface of the probe holder. The probe holder is inserted into the corresponding detection probe. The input end of the motor is electrically connected to the output end of the controller. The motor is started to adjust the angle of the probe holder, and the contraction and extension of the spring causes the detection probe to automatically fit with the mold, thereby facilitating damage detection at different positions of the mold.

[0010] Furthermore, the adjustment and detection unit also includes a placement seat, a baffle, and an industrial camera. The top surface of the placement seat is connected to the bottom end of the right-side electric push rod. Baffles are rotatably connected to both the left and right sides of the placement seat.

The hydraulic rod is activated to adjust the position of the limiting plate so as to limit the position of the mold.

[0014] Furthermore, the fixing unit also includes a sponge pad, a rubber pad, and a bracket. The sponge pad is adhered to the middle of the front side of the fixing plate, and brackets are fixed at both ends of the front side of the rubber pad. The brackets are inserted into the slots on the surface of the clamping plate. The sponge pad and the rubber pad can increase the stability of the mold fixing while preventing wear on the mold surface.

The limiting frame is fixed to one side of the top surface of the support frame, and the limiting groove is opened on the outside of the connecting plate. The limiting frame and the limiting groove are slidably connected to each other to increase the stability of the rotation of the support frame.

[0017] Furthermore, it also includes an audible and visual alarm, which is installed on the rear side inside the top frame. The input end of the audible and visual alarm is electrically connected to the output end of the controller. The audible and visual alarm can flash an alarm when a problem occurs during mold detection to remind personnel.

[0018] Compared with the prior art, the beneficial effects of the present invention are as follows: This mold damage detection device has the following advantages.

[0019] 1. The height of the support frame is adjusted by activating the electric telescopic rod, while the main motor drives the screw to rotate and adjust the position of the adjusting block.
