[0027] It should be noted that when an element is referred to as being "fixed to" another element, it may be directly on the other element or there may be an intermediate element. When an element is considered to be "connected to" another element, it may be directly connected to the other element or there may be an intermediate element at the same time.

[0028] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as those commonly understood by those skilled in the art of the present invention. The terms used herein in the specification of the present invention are only for the purpose of describing specific embodiments and are not intended to limit the present invention.

[0029] See also Figures 1 to 6 , is an automatic mold clamping device of an embodiment of the utility model, comprising a pressing assembly 10, and a clamping assembly 20 installed inside the pressing assembly 10. The pressing assembly 10 and the clamping assembly 20 are used to realize the mold clamping of the male mold 30 and the female mold 40. The pressing assembly 10 acts on the male mold 30, and the clamping assembly 20 acts on the female mold 40. Among them, the male mold 30 has handles 31 hinged on opposite sides thereof; the female mold 40 matches the male mold 30, and the female mold 40 has concave positions 41 on opposite sides thereof, and the concave positions 41 are used to correspondingly buckle the handles 31; and the female mold 40 has positioning holes 42 on opposite ends thereof.

[0030] The pressing assembly 10 includes a carrier plate 11, side plates 12 vertically connected to opposite sides of the bottom surface of the carrier plate 11, and rollers 13 rotatably mounted at opposite ends of each side plate 12; the axis of the rollers 13 is parallel to the plane where the side plates 12 are located. The rollers 13 are used to press the driving handle 31 downward to be buckled into the inside of the recess 41 after turning it inward.

[0031] The entire clamping assembly 20 is located between the two side plates 12. The clamping assembly 20 includes a clamping cylinder 21 installed in the middle of the bottom surface of the carrier plate 12, a translation plate 22 connected to the fingers of the clamping cylinder 21, a bracket 23 vertically connected to the end of each translation plate 22 away from the clamping cylinder 21, a positioning pin 24 installed on the inner surface of the opposite ends of each bracket 23, an extension piece 25 connected to the opposite ends of each bracket 23, and a limit pin 26 installed on the inner surface of each extension piece 25; the axis centerline direction of the limit pin 26 is consistent with the axis centerline direction of the positioning pin 24. In actual use, the positioning pin 24 is used to insert the positioning hole 42; the limit pin 26 is used to abut the outer side of the handle 31 to ensure that the handle 31 is buckled into the inside of the recess 41.

[0032] In this embodiment, the movement direction of the translation plate 22 is consistent with the axis direction of the roller 13 ; the axis direction of the positioning pin 24 is consistent with the axis direction of the roller 13 .

[0033] Please refer again Figures 4 to 6 In actual work, the male mold 30 and the female mold 40 are first matched and overlapped, and then the automatic mold clamping device falls, wherein the roller 13 gradually abuts and drives the handle 31 to turn inward until the handle 31 is buckled in the concave position 41, and then the finger cylinder 21 drives the two translation plates 22 to approach each other, so that the positioning pin 24 is correspondingly inserted into the positioning hole 42, and the limit pin 26 abuts against the outside of the handle 31 to ensure that the handle 31 is buckled in the concave position 41, so that the automatic mold clamping of the male mold 30 and the female mold 40 is realized. Compared with the traditional manual mold clamping method, the utility model uses the roller 13 to press down and drive the handle 31 of the male mold 30 to turn inward and buckle into the concave position 41 of the female mold 40, so as to realize the automatic mold clamping of the male mold 30 and the female mold 40, which greatly improves the degree of automation, saves labor, and effectively ensures the quality of mold clamping.

[0034] Furthermore, the two opposite ends of the finger-gripping cylinder 21 are respectively connected with reinforcing plates 27 , and the translation plate 22 is connected to the reinforcing plates 27 via a guide rail pair 28 , which can effectively improve the movement stability of the translation plate 22 .

[0035] The above-mentioned automatic mold closing device has a simple structure and is easy to use. It uses the roller 13 to press down and drive the handle 31 of the male mold 30 to turn inward and snap into the concave position 41 of the female mold 40, thereby realizing automatic mold closing of the male mold 30 and the female mold 40, greatly improving the degree of automation, saving labor, and effectively ensuring the quality of mold closing.
