[0028] In order to make the purpose, technical solution and advantages of the embodiment of the utility model clearer, the technical solution of the embodiment of the utility model will be clearly and completely described below in conjunction with the drawings of the embodiment of the utility model. Obviously, the described embodiment is a part of the embodiment of the utility model, not all of the embodiments. Based on the described embodiment of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0029] Example 1: Please refer to Figures 1 to 4 :

[0030] The utility model proposes a shell shaping cold press, comprising: a machine tool body 1; a cylinder 3 is installed on the internal top of the machine tool body 1, an alarm 2 is connected to the top surface of the machine tool body 1, and four groups of cylinder rods 4 are arranged in the inner cavity of the machine tool body 1; a pressing plate assembly 5 is installed on the cylinder rod 4; the pressing plate assembly 5 is composed of an upper pressing plate 51 and a lower pressing plate 52, an upper mold 6 is installed on the bottom surface of the upper pressing plate 51, and six groups of positioning fixtures 7 are installed on the bottom surface of the lower pressing plate 52; the upper mold 6 includes an upper template 61 and a connecting plate 62, and an elastic connecting member 6201 is connected between the upper template 61 and the connecting plate 62; a sensor is installed inside the positioning fixture 7, and the sensor is electrically connected to an external circuit controller, and the top surface of the positioning fixture 7 is fastened to a fastening plate 701 by setting a connecting rod 704; the top surface of the fastening plate 701 is connected to a lower template 702.

[0031] In the present disclosure, Figure 2As shown, a protective plate 101 is connected to the front end face of the machine tool body 1, and the bottom edge height of the protective plate 101 is the same as the initial position height of the upper pressure plate 51. A control system connected to an external circuit controller is arranged on the right side of the outside of the machine tool body 1. The control system can start and control the movement of the cylinder 3, control the upper template 61 to move up and down, and cool and pressurize the product to shape it. The protective plate 101 can prevent the product from being placed at too high a height and hitting the upper template 61 or the upper pressure plate 51, and provide protection when loading or unloading.

[0032] In the present disclosure, Figure 2 As shown, the width of the upper pressing plate 51 is smaller than the width of the machine tool body 1, and the top surface of the upper pressing plate 51 is fixedly connected to the bottom end of the push rod of the cylinder 3 through a rectangular plate, and the interior of the rectangular plate is penetrated by the cylinder rod 4, and a positioning hole is opened in the interior of the lower pressing plate 52. When the cylinder 3 is started by the controller, the push rod drives the rectangular plate and the upper pressing plate 51 to move downward, and also drives the upper mold 6 to move downward, and the product is cold-pressed. By setting the rectangular plate, the contact area between the push rod of the cylinder 3 and the upper pressing plate 51 is increased, thereby improving the cold pressing smoothness and increasing the cold pressing area.

[0033] In the present disclosure, Figure 4 As shown, a positioning pin 703 is provided in the middle of the lower template 702, and the bottom end of the positioning pin 703 is fixedly connected to the top surface of the positioning fixture 7, a connecting rod 704 is provided between the fastening plate 701 and the positioning fixture 7, and a lower spring rod 705 is provided between the fastening plate 701 and the lower template 702. When the protection pad 6102 moves down and contacts the positioning pin 703, the sensor inside the positioning fixture 7 performs stroke detection, and starts timing after the stroke is in place, and transmits information to the external circuit controller to perform shaping and pressure holding timing. If the sensor inside the positioning fixture 7 does not have stroke detection information, it outputs information and controls the alarm 2 to sound an alarm, and the upper template 61 is lifted to facilitate manual inspection of the product.

[0034] In the present disclosure, Figure 3 As shown, the interior of the upper template 61 is connected to the connecting plate 62 by setting a connecting nail 6103, and the connecting plate 62 is fixedly connected to the bottom surface of the upper pressure plate 51 by a bolt assembly. The bottom surface of the connecting plate 62 is provided with an upper spring rod 6101, and the bottom end of the upper spring rod 6101 is connected to a protective pad 6102, and the upper spring rod 6101 runs through the interior of the upper template 61. When the upper template 61 moves downward, it can be pre-calibrated to contact the lower template 702 through the upper spring rod 6101 and the protective pad 6102. At the same time, in the process of downward pressing, cooling and pressure holding molding, it can buffer the pressure during cold pressing to avoid sudden pressure on the product and cause molding failure.

[0035] In the present disclosure, Figure 2As shown, the alarm 2 is provided with four sets of light modes with different colors. A buzzer is provided inside the alarm 2 and is connected to the sensor. When the sensor detects that the travel distance is incorrect or the sensor is not in place, an alarm sound is issued through the buzzer and a light of a corresponding mode is turned on to give an alarm, so that the operator can check whether the product or equipment is faulty at the first time.

[0036] The working principle of this embodiment: the equipment is a four-column cylinder type one-out six-pressing machine, six groups of product positioning fixtures 7 are fixed on the lower pressure plate 52, and six groups of upper templates 61 are fixed on the lower side of the upper pressure plate 51 corresponding to the positioning fixtures 7. Each positioning fixture 7 has a sensor detection stroke. After the shell product is placed in the equipment and the upper template 61 is pressed down, the timing starts after the sensor detection stroke inside each positioning fixture 7 is in place, and the upper template 61 rises after the six groups of positioning fixtures 7 complete the set pressure holding time, and the cooling, pressure holding and shaping of the six groups of products are completed at the same time.
