[0024] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in 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.

[0025] Embodiment 1:

[0026] like Figures 1 to 4 As shown, a visualization mold structure includes a mold frame 1; a cavity insert 2 is provided on the movable mold side of the mold frame 1, a high-temperature transparent glass 3 is installed in the cavity insert 2, a pressure frame 4 is installed on the side of the high-temperature transparent glass 3 facing away from the mold frame 1, a camera 5 is provided on the side of the cavity insert 2 facing away from the mold frame 1, and the camera head of the camera 5 is aimed at the high-temperature transparent glass 3; an ejection structure 6 is provided on the fixed mold side of the mold frame 1.

[0027] During implementation, the cavity insert 2 is fixed to the mold frame 1 by four screws at the four corners. The four screws are removed during disassembly. The four screw holes of the cavity insert 2 are also provided with lifting threads, and the cavity insert 2 is removed through the lifting threads.

[0028] In this embodiment, the high-temperature transparent glass is fixed inside the cavity insert, and the cavity insert is fixed on the mold frame. During disassembly, the cavity insert is taken out first, and then the glass is replaced. When the high-temperature glass is eroded by aluminum liquid, the glass can be replaced without machine lowering the mold, which speeds up the test process.

[0029] Specifically, a first groove 11 is provided on the fixed mold side of the mold frame 1, and the ejection structure 6 is installed in the first groove 11. The ejection structure 6 includes a push rod fixing plate 61, and a second groove 60 is provided on the push rod fixing plate 61. An ejection connecting plate 62 is installed in the second groove 60. Both ends of the ejection connecting plate 62 pass through the push rod fixing plate 61 and the mold frame 1, and both ends of the ejection connecting plate 62 are connected to the output shaft 631 of the cylinder 63. The cylinder 63 is installed on the side of the mold frame 1, and the output shaft 631 of the cylinder 63 is set upward.

[0030] It should be noted that the ejector connecting plate 62 and the push rod fixing plate 61 are fixed together.

[0031] Specifically, an upper signal switch 12 and a lower signal switch 13 are installed on the mold frame 1 at a position on one side of the cylinder 63, and are spaced apart from each other. A touch component 64 for touching the upper signal switch 12 or the lower signal switch 13 is provided on one side of the end of the ejection connecting plate 62. The upper signal switch 12 is used to control the output shaft 631 of the cylinder 63 to stop moving upward, and the lower signal switch 13 is used to control the output shaft 631 of the cylinder 63 to stop moving downward.

[0032] It should be noted that since a camera needs to be placed behind the movable mold side in this application, it is impossible to make an ejection structure behind the movable mold like a conventional mold. In order to ensure that the product can remain in the fixed mold, all molding positions are made on the fixed mold side, and the movable mold position is a large flat surface.

[0033] In this embodiment, the ejection process of the ejection structure 6 is as follows: the output shaft 631 of the oil cylinder 63 pushes the ejection connecting plate 62 upward until the touch member 64 contacts the upper signal switch 12, and the upper signal switch 12 transmits a signal to the control system, and the control system controls the oil cylinder 63 to suspend the oil supply. At this time, the fixed mold is ejected; the retraction process of the ejection structure 6 is as follows: the output shaft of the oil cylinder 63 pulls the ejection connecting plate 62 downward to retract until the touch member 64 contacts the lower signal switch 13, and the lower signal switch 13 transmits a signal to the control system, and the control system controls the oil cylinder 63 to suspend the oil supply, and the retraction of the fixed mold is completed.

[0034] Specifically, the upper signal switch 12 and the lower signal switch 13 are both provided with a sensing shaft 14 on the side close to the touch member 64, and a curved surface 141 is provided at the end of the sensing shaft 14; the touch member 64 is provided with a contact surface on the side away from the ejection connecting plate 62, and the contact surface is in a shape of a middle convexity and upper and lower recesses, and the middle convexity of the contact surface is used to touch the curved surface of the sensing shaft.

[0035] In implementation, the arc surface 141 at the end of the sensing shaft 14 is specifically manifested as a cylinder 142 installed at the end of the sensing shaft 14 , and the radial direction of the cylinder 142 is the same as the length direction of the sensing shaft 14 ; or a sphere is installed at the end of the sensing shaft 14 .

[0036] Specifically, a mold foot pad 7 is installed on the movable mold side of the mold frame 1, and a slide rail 8 is provided on the inner side of the mold foot pad 7. The slide rail 8 is provided with a waist-shaped hole 81 extending along the thickness direction of the mold frame 1. A screw (not shown) is tightly installed in the waist-shaped hole 81, and one end of the screw is fixed to the mold foot pad 7; a mounting rod 51 is provided on the camera 5, and the camera 5 is fixed to the slide rail 8 through the mounting rod 51.

[0037] In this embodiment, before installing the camera, the distance between the slide rail 8 and the high-temperature perspective glass 3 can be fine-tuned by moving the slide rail 8 on the mold foot pad 7. Due to the static friction generated by the tight connection between the waist-shaped hole 81 on the slide rail 8 and the screw, when the slide rail 8 stops moving, the slide rail 8 and the mold foot pad 7 will be in a relatively stable connection relationship, and then the camera can be installed. In this way, the focal length of the camera can be fine-tuned, and the stability / focus of the camera during the mold movement process will not cause problems with the photography quality.

[0038] During implementation, there are a number of mold foot pads 7 arranged around the movable mold side of the mold frame 1 .

[0039] Specifically, a support rod 52 is installed on the camera 5 , a perspective plate 53 is installed on the support rod 52 , and the perspective plate 53 is located between the camera head and the high-temperature perspective glass 3 .

[0040] During implementation, the perspective plate 53 may be an acrylic plate, which can ensure that the camera 5 can take clear photos while preventing the camera 5 from being damaged by flying aluminum, thereby protecting the camera 5.

[0041] Specifically, a movable mold frame 9 is installed on the movable mold side of the mold frame 1 , and a square hole is opened on the movable mold frame 9 , and the square hole is aligned with the high-temperature transparent glass 3 .

[0042] The above embodiments only express several implementation methods of the utility model, and the descriptions are relatively specific and detailed, but they cannot be understood as limiting the scope of the utility model patent. It should be pointed out that for ordinary technicians in this field, without departing from the concept of the utility model, several modifications and improvements can be made, which are equivalent modifications and improvements made to the above embodiments based on the essential technology of the utility model, and all of them belong to the protection scope of the utility model.
