[0002] Aluminum products have a series of excellent properties, such as good strength, good weather resistance, low density, etc., and are often used to make radiator parts or exterior decoration parts. At present, in the production process of aluminum profiles, extrusion dies are needed to shape the aluminum profiles.

[0003] The aluminum extrusion die also needs to be processed before it is put into use. The aluminum extrusion die has various shapes, among which the cylindrical extrusion die is one of them. The cylindrical extrusion die needs to be moved whether it is being processed, in the process of processing or finished, and the die needs to be transported by a transmission device when it is moved;

[0004] Most of the transmission devices currently used are conveyor belt structures. When the conveyor belt structure is used to transport cylindrical molds, since the surface of the conveyor belt is flat, it will cause the cylindrical mold to roll during transportation, which may cause unstable transportation and cause the cylindrical mold to fall and be damaged.

[0005] Therefore, it is urgent to improve the extrusion die to solve the above-mentioned problems. Summary of the invention

The contact surfaces of the two semi-cylindrical shells are respectively provided with a first strong magnetic plate and a second strong magnetic plate that attract each other. One of the semi-cylindrical shells is fixedly connected to the circular base, and the outer side of the bottom of the other semi-cylindrical shell is hinged to the circular base through a hinge.

[0015] Preferably, the pressure sensor is arranged on the upper end surface of the circular base, and a plurality of compression springs are also arranged on the upper end surface of the circular base. The plurality of compression springs are distributed on the outside of the pressure sensor, and the upper end surfaces of the plurality of compression springs support a pressure plate, and a pressure block is arranged on the lower end surface of the pressure plate. The pressure sensor establishes a communication connection with the transmission mechanism.

[0016] Preferably, the top mechanism includes a protective body arranged above the outer side of one of the semicircular shells and an electric telescopic rod arranged inside the protective body and extending into the mold placement cavity, and the electric telescopic rod establishes a communication connection with the object sensor.

During transmission, the plurality of mold placement cavities are also in a rotating state;

[0021] S2: When the mold placement mechanism slides to the end point, it will squeeze the sensing buffer mechanism, which will be sensed by the second pressure sensor, and then the transmission mechanism will stop running. When the mold placement mechanism passes the object sensor, the object sensor senses that an object has passed, and will transmit a signal to the electric telescopic rod. The electric telescopic rod will push the cylindrical mold outward, thereby pushing open the hinged semi-cylindrical shell to eject the cylindrical mold placed in the mold placement cavity. While the electric telescopic rod is running, several of the mold placement cavities are in a uniform rotation state, so that all the cylindrical molds placed in each of the mold placement cavities can be ejected one by one.

[0023] 1. By placing the cylindrical mold inside the mold placement cavity for clamping and fixing, and then using the transmission mechanism for transmission and transportation, compared with the traditional planar conveyor belt transmission and transportation, the cylindrical mold can be fixed and stably transmitted and transported. By using the setting of connecting the pressure sensor with the transmission mechanism electrical signal, the fixed cylindrical mold can be automatically transported.

[0024] 2. By utilizing the setting of the induction buffer mechanism, the automatic stopping effect of the mold placement mechanism can be improved. By utilizing the setting of the ejection mechanism, automatic material discharge can be achieved after the mold placement mechanism is automatically transported to the end point, further improving the automation effect of the equipment.

Those skilled in the art should understand that hardware manufacturers may use different terms to refer to the same component. This specification and claims do not use differences in names as a way to distinguish components, but use differences in the functions of components as the criteria for distinction.
