Abstract
Description
Technical Field
[0001] The present invention relates to the technical field of forming molds, and particularly relates to a forming mold for a temperature-controlled heat conduction tube. Background Art
[0002] As an efficient heat transfer element, the heat conduction tube is widely used in the fields of heat dissipation of electronic devices, thermal management of aerospace, etc. Its forming quality directly determines the heat transfer performance and service life, and precise temperature control and efficient demolding are the core difficulties in the manufacturing process. The following technical bottlenecks generally exist in traditional forming molds:
[0003] 1. Forming defects caused by insufficient temperature control accuracy:
[0004] Conventional molds mostly adopt a single heating or cooling method, and there are problems such as large temperature gradients and response lags. Especially in the phase change material filling stage, local overheating or uneven cooling is likely to cause defects such as pores and warping;
[0005] 2. High dependence on labor and prominent demolding risks:
[0006] Existing molds mostly rely on mechanical ejector rods for demolding, and operators need to intervene closely to pick up the parts. Since the heat conduction tube fits tightly with the mold cavity after forming, forced ejection is likely to cause scratches or even fractures on the tube wall; Therefore, we propose a forming mold for a temperature-controlled heat conduction tube to solve this problem.

[0021] The beneficial effects of the present invention are as follows:
[0022] 1. In the present invention, for the forming mold of the temperature-controllable heat-conducting tube, by starting the hydraulic cylinder to drive the upper mold to move upward, at the same time, the cross plate, the vertical plate and the lifting plate are driven to move upward through the mounting plate, and the return spring is compressed. After the lifting plate contacts the linkage plate, it pushes the linkage plate to move upward synchronously, and drives the sealing plate to move horizontally through the connecting rope. The lifting plate also drives the two trapezoidal plates to move upward. When the two trapezoidal plates contact the corresponding connecting columns, they push the two connecting columns to approach each other, so that the two trapezoidal clamping plates approach each other, and the trapezoidal clamping plates are disengaged from the trapezoidal card slots, releasing the fixation of the vertical plate and the piston plate. The piston plate moves upward under the action of the return spring. When the gap between the upper mold and the lower mold is large enough, a plurality of heat-conducting tubes to be formed and processed are placed in the lower forming mold grooves of the lower mold. Then, the hydraulic cylinder is started to control the upper mold to move upward, so that part of the inner wall of the upper forming mold groove of the upper mold contacts the heat-conducting tube. When the second pressure sensor monitors a slight increase in pressure, the controller is used to control the hydraulic cylinder to stop feeding. Then, the first electric heating plate and the second electric heating plate are started to heat the lower mold and the upper mold, so as to heat the heat-conducting tube, thereby eliminating internal stress. The temperature is monitored by the first temperature sensor and the second temperature sensor;
[0023] 2. In the present invention, for the forming die of the temperature-controllable heat conduction tube, the upper die is driven downward by starting the hydraulic cylinder to achieve mold closing, so that the heating tube is bent and formed by the extrusion of the upper forming die groove and the lower forming die groove. By introducing cooling water into the first cooling hole and the second cooling hole, the lower die and the upper die are cooled, thereby realizing the cooling of the heated tube after bending and ensuring the stability of the formed shape. During the downward movement of the upper die, the lifting plate is driven downward by the mounting plate, the cross plate and the push plate, and the lifting plate drives the piston plate downward, thereby squeezing the air in the sealing frame to form compressed air. When the upper die and the lower die are completely fitted, the trapezoidal clamping plate is clamped into the trapezoidal card slot to fix the piston plate;
[0024] 3. In the present invention, for the forming die of the temperature-controllable heat conduction tube, the upper die is driven upward by starting the hydraulic cylinder to achieve mold opening. At this time, the lifting plate moves upward synchronously with the upper die, but the piston plate will not move upward because it is fixed by the trapezoidal clamping plate, so that the return spring can be squeezed. During the upward movement of the lifting plate, it first contacts the linkage plate, drives the sealing plate to move horizontally, and releases the sealing of the front end of the horizontal tube, so that the compressed air in the sealing frame is introduced into the plurality of air injection holes through the horizontal tube and the plurality of air injection pipes and ejected from the top of the air injection holes, thereby ejecting the formed heating plate and facilitating blanking. Then, the trapezoidal plate is disengaged from the connecting column and pushes the two trapezoidal clamping plates to approach each other, releases the fixation of the piston plate, and enables the piston plate to reset under the action of the return spring, facilitating the next cycle of use;
[0025] 4. In the present invention, for the forming die of the temperature-controllable heat conduction tube, the precise temperature control of the forming die is realized through the cooperation of the set cooling holes, the electric heating plate and the temperature sensor. Through the linkage design of the inflation mechanism and the locking mechanism, when the hydraulic cylinder drives the upper die to move, the air in the sealing frame is compressed synchronously, and the compressed gas is automatically released through the air injection holes to eject the formed part during the mold opening stage, completely avoiding the risk of manual part taking. Through the deep integration of temperature control optimization, automatic demoulding and structural reliability design, the qualified rate and production efficiency of the heat conduction tube forming are significantly improved, and at the same time, the energy consumption and the cost of manual intervention are reduced.

At this time, the lifting plate 503 moves upward synchronously with the upper die 3, but the piston plate 502 will not move upward because it is fixed by the trapezoidal clamping plate 805, so that the return spring 507 can be compressed. During the upward movement of the lifting plate 503, it first contacts the linkage plate 16, drives the sealing plate 10 to move horizontally, and releases the sealing of the front end of the horizontal tube 7, so that the compressed air in the sealing frame 501 is introduced into a plurality of air injection holes 205 through the horizontal tube 7 and a plurality of air injection pipes 701, and is ejected from the top of the air injection holes 205, thereby ejecting the formed heating plate, facilitating the blanking. Then, the trapezoidal plate 508 is disengaged from the connecting column 804 and pushes the two trapezoidal clamping plates 805 closer to each other, releases the fixation of the piston plate 502, and enables the piston plate 502 to reset under the action of the return spring 507, facilitating the next cycle of use.
