Description

Technical Field

[0001] The utility model relates to the technical field of molds, in particular to a hot pressing mold. Background Art

[0002] Hot press dies are tools used in the hot press forming process. Hot press forming is a manufacturing process in which a material (usually a thermoplastic or composite) is heated to a specific temperature and then pressed into shape using pressure. The main function of the hot press die is to ensure that the material receives uniform heat and pressure during the forming process, thereby achieving the desired shape and properties.

[0003] In large-scale production or when production efficiency needs to be improved, multiple hot pressing heads are used together in hot pressing molds. However, when multiple hot pressing heads are used together in some existing devices, due to the height difference between each hot pressing head and the hot pressing point, some areas of the component may not be fully heated or pressed. The riveted products are prone to gaps, and the quality is difficult to guarantee. Utility Model Content

[0004] In order to solve the above technical problems, the utility model provides a hot pressing mold.

[0005] The utility model is implemented by the following technical solution: a hot pressing mold, including a mounting plate, a connecting rod fixedly connected to the top of the mounting plate, a mounting hole opened on the mounting plate, a protective sleeve slidably connected inside the mounting hole, a heat-conducting outer shell fixedly connected to the inner wall of the protective sleeve, a fixing ring fixedly connected to the outer wall of the heat-conducting outer shell, a spring fixedly connected to the top of the fixing ring, the heat-conducting outer shell is located on the inner side of the spring, and the top of the spring is in contact with the bottom of the mounting plate.

[0006] Through the above technical solution, the protective cover can prevent the heat-conducting housing from contacting the mounting plate, thereby reducing the wear of the heat-conducting housing and increasing the service life of the device.

[0007] As a further improvement of the above solution, the diameter of the fixing ring is larger than the diameter of the protective sleeve, the diameter of the spring is larger than the diameter of the protective sleeve, and the diameter of the spring is smaller than the diameter of the fixing ring.

[0008] As a further improvement to the above solution, a limiting groove is provided on the outer wall of the mounting plate, and a limiting ring is clamped inside the limiting groove.

[0009] With the above technical solution, the limiting groove and the limiting ring can prevent the heat-conducting housing from falling from the mounting hole due to gravity, thereby affecting the use of the device.

[0010] As a further improvement of the above solution, a threaded rod is threadedly connected to the bottom of the heat-conducting housing, a thermal pressing head is fixedly connected to the bottom end of the threaded rod, and a fixing groove is opened on the outer wall of the mounting plate.

[0011] Through the above technical solution, such a configuration is for threaded connection with the heat-conducting shell through the threaded rod, so as to facilitate installation and disassembly of the thermal pressure head, thereby facilitating maintenance and replacement of the thermal pressure head.

[0012] As a further improvement of the above solution, a clamp is provided inside the fixing groove, a temperature sensor is provided in contact with the inner wall of the clamp, and the temperature sensor is fixedly connected to the inside of the fixing groove through the clamp.

[0013] With the above technical solution, the temperature sensor is fixed in the fixing groove by the clamp, so that the temperature of the heat-conducting housing can be monitored, thereby facilitating the temperature adjustment of the device.

[0014] As a further improvement of the above solution, the fixing groove is located above the limiting groove, and the size of the clamp matches the size of the fixing groove.

[0015] As a further improvement of the above solution, a heating core is fixedly connected to the inside of the heat-conducting shell, the top of the heating core passes through the top of the heat-conducting shell and extends, and the top of the heating core is fixedly connected to a connecting wire.

[0016] Through the above technical solution, the heat-conducting shell and the hot pressing head are heated by the heating core, so as to facilitate hot pressing and forming of the workpiece.

[0017] Compared with the prior art, the beneficial effects of the present invention are:

[0018] When the utility model pushes the connecting rod to descend through the external device, the connecting rod will cause the mounting plate to descend, and the heat-conducting shell will also descend due to gravity. When the hot pressing head contacts the hot pressing material, the mounting plate continues to descend. At this time, due to the obstruction of the hot pressing material, the heat-conducting shell will rise relative to the mounting plate, thereby compressing the spring, and the reaction force of the spring will make the hot pressing head and the hot pressing material fit more closely, which can effectively avoid that some areas of the component are not fully heated or pressed due to the height difference between the hot pressing head and the hot pressing point, thereby improving the hot pressing quality.

[0019] The utility model is that the thermal pressure head is connected to the threaded rod, and the threaded rod is threadedly connected to the heat-conducting shell. Therefore, the thermal pressure head can be rotated clockwise, and the thermal pressure head drives the threaded rod to rotate, thereby separating the threaded rod from the heat-conducting shell, thereby facilitating the maintenance and replacement of the thermal pressure head.

[0020] The utility model fixes temperature sensors on the heat-conducting housing through clamps, so that each hot pressing head can independently set the temperature and alarm parameters, thereby monitoring and adjusting the temperature of each hot pressing head, further improving the hot pressing quality.
