[0029] The technical solutions in the embodiments of the utility model will be clearly and completely described below in conjunction with the drawings in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, rather than all of the embodiments; based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the utility model.

[0030] It should be noted that the words "front", "rear", "left", "right", "up" and "down" used in the following description refer to directions in the drawings, and the words "inside" and "outside" refer to directions toward or away from the geometric center of a specific component, respectively.

[0031] like Figures 1 to 6As shown, an adjustable punching machine for rubber products in one embodiment of the utility model includes: a punching machine body 1, a fixing plate 2 and a lower mold 3.

[0032] Among them, the fixing plate 2 is installed on the table top of the punching machine body 1, and the fixing plate 2 is used to fix the lower mold 3. At the same time, the fixing plate 2 is also convenient for adjusting the position of the lower mold 3, so that the plastic product on the lower mold 3 can be stamped at different positions without re-fixing the plastic product on the lower mold 3, thereby ensuring the stamping efficiency of the plastic product.

[0033] In addition, a plurality of grooves 201 are formed on the fixed plate 2 , and movable columns 202 are slidably arranged in the grooves 201 . The movable columns 202 can attract the magnetic plate 302 , and then the position of the rear lower mold 3 can be fixed and adjusted to facilitate the stamping of the plastic product on the lower mold 3 .

[0034] Specifically, the movable column 202 is made of magnetic metal, which is easy to attract the magnetic plate 302, and then can fix the lower mold 3, so that the lower mold 3 can cooperate with the upper mold on the punching machine body 1 to punch plastic products.

[0035] In addition, an elastic rope 203 is connected between the movable column 202 and the bottom wall of the groove 201. When the movable column 202 is attracted by the magnetic plate 302, the elastic rope 203 is pulled and stretched, so that the movable column 202 can protrude from the groove 201. Figure 3 When the movable column 202 is not attracted by the magnetic plate 302, the elastic rope 203 returns to its original state, so that the movable column 202 can be stored in the groove 201. Figure 2 Status shown.

[0036] Furthermore, a stabilizing ring 204 is installed at the end of the groove 201, and one end of the movable column 202 passes through the stabilizing ring 204. The stabilizing ring 204 is used to stabilize the movable column 202, so that the movable column 202 is not easy to shake in the groove 201, and the adsorption firmness of the movable column 202 and the magnetic plate 302 is ensured.

[0037] like Figures 1 to 6 As shown, the lower mold 3 is arranged on the fixed plate 2, and the lower mold 3 is used to fix the plastic product, and the plastic product is punched by cooperating with the upper mold of the punching machine body 1.

[0038] A pair of release mechanisms are installed in the lower mold 3, and the release mechanisms correspond to the movable columns 202. A pair of movable grooves 301 are cut on one side of the lower mold 3 close to the fixed plate 2, and the pair of release mechanisms correspond to the pair of movable grooves 301, respectively, and the movable grooves 301 are used to accommodate the magnetic plate 302.

[0039] like Figures 1 to 6As shown, the release mechanism includes a magnetic plate 302, which is slidably disposed in the movable groove 301. The magnetic plate 302 is attracted to the movable columns 202. The lower mold 3 can be fixed by attracting the magnetic plate 302 and a plurality of movable columns 202 to ensure the stamping effect of the plastic product.

[0040] When the pull rope 303 is not pulled, the magnetic plate 302 approaches the movable column 202 under the action of the spring, and several movable columns 202 are attracted by the magnetic plate 302 and overcome the tension of the elastic rope 203, so that the movable columns 202 can be inserted into the movable groove 301 and contact the magnetic plate 302. At this time, the lower mold 3 is fixed by the attraction of several movable columns 202 and the magnetic plate 302.

[0041] When the pull rope 303 is pulled, the spring is compressed and the magnetic plate 302 moves in the movable groove 301, so that the attraction of the magnetic plate 302 to the movable column 202 is smaller than the pulling force of the elastic rope 203. At this time, the movable column 202 is received in the groove 201 and the lower mold 3 is not fixed.

[0042] The magnetic plate 302 is connected with a bracket for connecting a pull rope 303 , and the bracket is connected with a pull rope 303 . The magnetic plate 302 can slide in the movable groove 301 by pulling the pull rope 303 , which is convenient for operation.

[0043] In addition, a pull rod 304 is connected to one end of the pull rope 303 away from the bracket to facilitate pulling the pull rope 303 and is also used to connect the nut 305 to fix the position of the magnetic plate 302, thereby facilitating the adjustment of the position of the lower mold 3.

[0044] Specifically, a nut 305 is threadedly connected to the pull rod 304, and the pull rod 304 and the nut 305 are both arranged outside the lower mold 3. By pulling the pull rod 304 and then rotating the nut 305, the position of the magnetic plate 302 can be fixed, and there is no need to pull the pull rod 304 all the time, which facilitates the adjustment of the position of the lower mold 3.

[0045] like Figures 1 to 6 As shown, a pair of fixed pulleys 306 are installed in the lower mold 3, and the pair of fixed pulleys 306 correspond to the pair of pull ropes 303 respectively. The fixed pulleys 306 are used to guide the sliding of the pull ropes 303 to reduce the wear of the pull ropes 303 and the inner wall of the lower mold 3.

[0046] Among them, a pair of side walls of the magnetic plate 302 are respectively connected with sliders, and a pair of side walls of the movable groove 301 are respectively opened with limiting grooves 307. The sliders are slidably arranged in the limiting grooves 307 to limit the magnetic plate 302, so that the magnetic plate 302 is not easily skewed in the movable groove 301, thereby ensuring the adsorption effect of the magnetic plate 302 and several movable columns 202.

[0047] When in use, the plastic product is fixed on the lower mold 3, and the upper mold of the punching machine body 1 cooperates with the lower mold 3 to perform a punching operation on the plastic product.

[0048] When the plastic product needs to be stamped in different directions, the pull rod 304 is pulled, and the pull rod 304 pulls the magnetic plate 302 to move in the movable groove 301 through the pull rope 303, so that the magnetic plate 302 is away from the movable column 202. At this time, the attraction of the magnetic plate 302 to the movable column 202 is smaller than the pulling force of the elastic rope 203, and the movable column 202 will be stored in the groove 201, and the lower mold 3 is not fixed, and the staff can adjust the position of the lower mold 3.

[0049] After the position of the lower mold 3 is adjusted, the nut 305 is loosened, and the magnetic plate 302 is close to the movable column 202 under the action of the spring. The movable columns 202 are attracted by the magnetic plate 302 and overcome the tension of the elastic rope 203, so that the movable columns 202 can be inserted into the movable groove 301 and contact the magnetic plate 302. At this time, the lower mold 3 is fixed by the attraction of the movable columns 202 and the magnetic plate 302. Then, the upper mold of the punching machine body 1 and the lower mold 3 cooperate with each other to perform a punching operation on the plastic product.

[0050] The present application provides a fixed plate 2 and a lower mold 3 to facilitate the staff to flexibly adjust the position of the lower mold 3 without re-fixing the rubber product on the lower mold 3, thereby simplifying the adjustment steps and ensuring the stamping efficiency of the plastic product.
