[0029] The following is a further detailed description of the present invention in conjunction with specific embodiments:

[0030] like Figure 1 As shown, a hot pressing magnetic ring forming machine includes a feeding mechanism 1, a stamping mechanism 2, a demoulding component 3 and a heat dissipation component 4.

[0031] like Figure 2 and Figure 3As shown, the feeding mechanism 1 includes a first driver 11 arranged along a first direction, and the execution end of the first driver 11 is provided with a first cylinder 12 in a vertical direction, and drives the first cylinder 12 to move along the first direction, and a hook 13 is fixed to the execution end of the first cylinder 12. The top of the mold 5 has a preset hole, and the hook 13 is driven by the first cylinder 12 to perform a lifting movement so that it is inserted into the preset hole, and driven by the first driver 11 to carry the mold 5 along the first feeding track 14 into the stamping mechanism 2. In this embodiment, in order to ensure the stroke of the hook 13 and save the size of the first driver 11, the first cylinder 12 and the hook 13 are both set to two, and the mold 5 is pushed alternately. Among them, the first driver 11 is composed of a servo motor and a screw mechanism.

[0032] like Figure 4 As shown, the punching mechanism 2 includes a punch 21 arranged along the vertical direction. The punch 21 performs a punching movement under the drive of a hydraulic cylinder 22 to punch and form the magnetic ring 53 in the mold 5.

[0033] After the stamping work is completed, the hook 13 pulls the mold 5 out of the stamping station and places it at the entrance of the second feed track 16 perpendicular to the first feed track 14. Then, the mold 5 is pushed into the position of the second feed track 16 adjacent to the demolding assembly 3 under the action of the second cylinder 15 set corresponding to the second feed track 16.

[0034] like Figure 5 , Figure 6 and Figure 7 As shown, the demoulding assembly 3 includes a separation mechanism 31 and a demoulding mechanism 32. The mold 5 is Figure 2 In this embodiment, the second driver 33 includes an abutment portion 331 abutting against the mold 5, and a driving portion 332 composed of a servo motor and a screw rod for driving the abutment portion 331 (in order to make the separation mechanism 31 and the demoulding mechanism 32 more intuitive, Figure 5 , Figure 6 and Figure 7 The second driver 33 is hidden). In addition, it is explained here that Fig. 9 As shown, the mold 5 in this embodiment is composed of a first mold plate 51 and a second mold plate 52 arranged in sequence from top to bottom. The magnetic ring 53 is formed in the mold cavity formed by the first mold plate 51 and the second mold plate 52, so when demolding, the separation mechanism 31 needs to be used to separate the first mold plate 51 from the second mold plate 52.

[0035] like Figure 5 and Figure 6As shown, the separation mechanism 31 includes a separation partition 311 and a separation push rod 312. The separation push rod 312 penetrates the first template 51 and abuts against the second template 52. Under the action of the separation cylinder, the second template 52 is separated and the second template 52 falls off from the separation hole 313 provided below the separation push rod 312. The separation partition 311 is provided on both sides of the mold 5, and is synchronously embedded in the card slot between the first template 51 and the second template 52 when the second template 52 is separated, so as to support the first template 51.

[0036] like Figure 7 As shown, the demoulding mechanism 32 includes a demoulding head 321 and a demoulding pressing plate 322. Driven by the demoulding driver, the demoulding head 321 penetrates the first template 51 to demould the magnetic ring 53 in the first template 51. The demoulding pressing plate 322 is synchronously abutted against one end of the first template 51 close to the demoulding head 321 during the process of the demoulding head 321 being withdrawn from the first template 51, so as to prevent the first template 51 from being lifted up by the demoulding head 321 due to adhesion.

[0037] like Figure 8 As shown, the heat dissipation assembly 4 is used to dissipate heat from the template after demoulding. It includes a pair of fans 41, and a first heat dissipation station and a second heat dissipation station are arranged below the pair of fans 41 to dissipate heat from the first template 51 and the second template 52 respectively. The heat dissipation assembly 4 also includes a first heat dissipation mechanism 42 and a second heat dissipation mechanism 43 respectively arranged corresponding to the separation station and the demoulding station.

[0038] Among them, the first heat dissipation mechanism 42 includes a first supporting plate 421 and a first heat dissipation pull plate 422. The first supporting plate 421 is arranged below one side of the demoulding station, and is lifted and lowered under the action of the first lifting cylinder 423, so as to enter the demoulding station. The second driver 33 pushes the first template 51 that has completed demoulding into the first supporting plate 421, and then the first template 51 is reset. Under the action of the first pull plate driver, the first heat dissipation pull plate 422 pulls the first template 51 from the first supporting plate 421 into the first heat dissipation station where the fan 41 is set. In this embodiment, the first pull plate driver adopts a cylinder.

[0039] The second heat dissipation mechanism 43 includes a second supporting plate 431, a second heat dissipation pull plate 432, and a third heat dissipation pull plate 433. The second supporting plate 431 is arranged below the separation hole 313, and is lifted and lowered under the action of the second lifting cylinder, thereby entering the separation station, and is used to receive the separated and dropped second template 52. After receiving the second template 52, the second supporting plate 431 is reset, and the second heat dissipation pull plate 432 and the third heat dissipation pull plate 433, under the action of the second pull plate driver and the third pull plate driver, respectively, pull the second template 52 from the second supporting plate 431 into the second heat dissipation station set corresponding to the fan 41. In this embodiment, the second pull plate driver and the third pull plate driver are both composed of a servo motor and a screw mechanism.

[0040] Preferably, in this embodiment, the second heat dissipation pull plate 432 includes a fixed plate 4321 and a movable plate 4322, wherein the fixed plate 4321 is fixed to the execution end of the second pull plate driver, and one end of the movable plate 4322 is hinged to the fixed plate 4321, and forms an angle with the fixed plate 4321 under the action of gravity. In the process of pushing the second template 52 toward the second heat dissipation station, the movable plate 4322 abuts against the second template 52, and maintains the angle with the fixed plate 4321 under the action of the limiting structure, and while pushing the second template 52 to the maximum stroke, provides space for the second supporting plate 431 to support another second template 52. In the process of resetting the second heat dissipation pull plate 432, the movable plate 4322 abuts against the second template 52, so that the angle with the fixed plate 4321 is reduced, so that it can slide over the second template 52, and then repeat the movement of pulling the second template 52 into the second heat dissipation station.

[0041] The above embodiments are only for illustrating the technical concept and features of the utility model, and their purpose is to enable people familiar with this technology to understand the content of the utility model and implement it accordingly, and they cannot be used to limit the protection scope of the utility model. For those skilled in the art, it is obvious that the utility model is not limited to the details of the above exemplary embodiments, and the utility model can be implemented in other specific forms without departing from the spirit or basic features of the utility model. Therefore, no matter from which point of view, the embodiments should be regarded as exemplary and non-restrictive. The scope of the utility model is limited by the attached claims rather than the above description, so it is intended to include all changes within the meaning and scope of the equivalent elements of the claims in the utility model.
