Description

Technical Field

[0001] The utility model relates to the technical field of molds for head processing, in particular to a head hydraulic mold. Background Art

[0002] The head is widely used to close the end of the container. The manufacturing method of the head is usually stamping and spinning. During manufacturing, the head blank is first placed on the lower mold, and then the upper mold is pressed downward and closed with the mold where the head blank is placed, so that the head is formed inside the mold, and then the mold is separated and the formed head is taken out.

[0003] The current hydraulic mold for the head directly uses an upper mold and a lower mold. After pressing, it needs to be taken out manually. At this time, the formed head may fit with the lower mold and be difficult to take out. In addition, after the head raw material is formed by the extrusion force, tiny debris may fall off, affecting the next processing of the head. Utility Model Content

[0004] The technical problem to be solved by the utility model is to overcome the deficiencies of the prior art and provide a head hydraulic mold which can overcome the above problems or at least partially solve the above problems.

[0005] In order to achieve the above purpose, the utility model adopts the following technical solutions:

[0014] 2. The head hydraulic mold allows the gas in the lower mold to flow back into the gas storage cavity through the injection pipe, thereby effectively preventing the excessive air pressure on the lower side of the head raw material from affecting its molding effect.

[0015] 3. The head hydraulic mold drives the sealing ejector rod to rotate through the spiral groove and the driving block, so that the gas ejected from the injection pipe is rotated and injected, thereby effectively improving the cleaning effect of the lower mold.

DETAILED DESCRIPTION

[0023] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0024] Example 1: Reference Figure 1-Figure 5 A head hydraulic mold includes: a fixed barrel 1, and also includes: a lower mold 101, fixed in the fixed barrel 1; a hydraulic cylinder 105, symmetrically arranged on both sides of the fixed barrel 1; a top plate 106, fixed between the output ends of the two hydraulic cylinders 105; an upper mold 107, fixed on the lower side of the top plate 106, and the upper mold 107 matches the lower mold 101; an air storage cavity 102, arranged in the fixed barrel 1; a sealing ejector rod 202, sealingly sliding between the lower mold 101 and the air storage cavity 102; a connecting ring 203, fixed at the lower end of the sealing ejector rod 202; a plurality of injection pipes 208, arranged in the sealing ejector rod 202; a fixed tube 2, fixed in the fixed barrel 1, and the fixed tube 2 matches the sealing ejector rod 202; a spring 205, arranged between the bottom of the fixed tube 2 and the connecting ring 203; a controller 108, fixed on the top plate 106; and an air supply component for supplying air to the air storage cavity 102.

[0025] The air supply assembly includes an air pump 103 disposed on one side of the fixed barrel 1 , and a connecting pipe 104 is fixedly connected between the output end of the air pump 103 and the air storage chamber 102 .

[0026] A pressure cylinder 302 is symmetrically fixedly connected to the top plate 106 , a sliding rod 301 is sealed and slidable inside the pressure cylinder 302 , and the sliding rod 301 passes through the top plate 106 . A pressure plate 3 is provided on the lower side of the top plate 106 , and the pressure plate 3 is fixedly connected to the sliding rod 301 .

[0027] When processing the head, the head raw material is placed on the upper side of the upper mold 107, and the hydraulic cylinder 105 is controlled by the controller 108 to drive the top plate 106 to move downward. At this time, the pressure plate 3 first contacts the head raw material and presses its edge, and then the upper mold 107 presses the head raw material downward. The head raw material squeezes the sealing top rod 202 downward to slide, and the upper mold 107 and the lower mold 101 cooperate with each other to squeeze it to form a head.

[0028] After the head processing is completed, the controller 108 controls the hydraulic cylinder 105 to lift the top plate 106. At this time, the sealing push rod 202 is lifted upward under the action of the spring 205, and the processed head is pushed upward, so as to facilitate the removal of the processed head. In addition, when the controller 108 controls the hydraulic cylinder 105 to lift, the controller 108 turns on the air pump 103, and the air pump 103 supplies air to the air storage chamber 102. The gas in the air storage chamber 102 is ejected through the injection pipe 208, thereby effectively cooling the processed head and blowing out the impurities in the lower mold 101, effectively improving the cleaning effect of the lower mold 101.

[0029] When the upper mold 107 squeezes the end cap material downward, the gas in the lower mold 101 flows back into the gas storage chamber 102 through the gas injection pipe 208, thereby effectively preventing the gas pressure on the lower side of the end cap material from being too high and affecting its molding effect.

[0030] It should be noted that after the controller 108 turns on the air pump 103, the controller 108 automatically controls the air pump 103 to turn off after the air pump 103 works for a set time.

[0031] Example 2: Reference Figure 1-Figure 5 , a head hydraulic mold, is basically the same as Example 1, further, a rotating ring 204 is rotatably connected to the lower side of the connecting ring 203, and the rotating ring 204 matches the fixed tube 2, one end of the spring 205 is fixedly connected to the rotating ring 204, and a driving component for driving the sealing top rod 202 to rotate is provided in the air storage chamber 102.

[0032] The driving assembly includes a spiral groove 201 provided in the fixed tube 2 , a fixing rod 206 is fixedly connected to the lower end of the sealing top rod 202 , and a driving block 207 matching the spiral groove 201 is fixedly connected to the fixing rod 206 .

[0033] The upper end of the air injection pipe 208 is inclined upward.

[0034] When the sealing ejector pin 202 slides up and down, the spiral groove 201 cooperates with the driving block 207 to drive the sealing ejector pin 202 to rotate, so that the gas ejected from the injection pipe 208 is injected in a rotating manner, thereby effectively improving the cleaning effect on the lower mold 101.

[0035] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes within the technical scope disclosed by the present invention according to the technical scheme and the utility model concept of the present invention, which should be covered by the protection scope of the present invention.
