Description

Technical Field

[0001] The utility model relates to a vulcanizing machine feeding device used for producing EVA soles, belonging to the technical field of vulcanizing machines used for producing soles. Background Art

[0002] A sole vulcanizing machine is a device used for vulcanizing and molding EVA soles. However, the sole mold of the existing vulcanizing machine is directly placed on the vulcanizing machine. Due to the limited space of the vulcanizing machine frame, the sole mold can only be operated in a relatively narrow space. When operating the sole mold, it is necessary to be very careful when opening the mold and pulling the mold to remove the material. Sometimes, the heating plate on the vulcanizing machine may burn you. In view of the above shortcomings, the utility model proposes a vulcanizing machine feeding device for EVA sole production. Utility Model Content

[0003] In view of the deficiencies in the prior art, the utility model aims to provide a vulcanizing machine feeding device for the production of EVA soles to solve the existing problems.

[0004] In order to achieve the above-mentioned purpose, the utility model is realized through the following technical solutions: a vulcanizing machine feeding device for EVA sole production, which structure includes a vulcanizing machine, and a feeding device is horizontally arranged in the middle of the vulcanizing machine, and the front side of the feeding device extends to the outside of the front end of the vulcanizing machine, a vulcanized shoe mold is movably placed on the top surface of the feeding device, and the vulcanizing machine is composed of a frame, a cylinder, an upper push plate and a heated pressing plate. The feeding device includes two slide rails, and a movable pull plate group is movably sleeved between the top surfaces of the two slide rails, and a support frame is provided at the lower end of the front side of the two slide rails, and the other end of the support frame is fixed to the outside of the front side of the frame;

[0005] The movable pull plate group includes a pull plate, and multiple sliders are set on the bottom surfaces of the left and right sides of the pull plate, and multiple mold positioning columns are vertically set on the left and right sides of the top surface of the pull plate. A clamping seat is set at the rear end of the top surface of the pull plate at a horizontal and rearward tilt.

[0006] As a further improvement, a mold pushing opening for movably placing the vulcanized shoe mold is opened in the middle of the top surface of the pull plate, and the opening area of ​​the mold pushing opening is larger than the area of ​​the upper push plate.

[0007] A further improvement is that a tapered surface is provided on the circumference of the upper end of each mold positioning column.

[0008] A further improvement is that the vulcanized shoe mold includes a sole mold, which is composed of a bottom mold and a top mold hingedly covered together. Two card edge strips are provided on the left and right sides of the bottom mold of the sole mold, and the two card edge strips are provided with card holes corresponding to each mold card column.

[0009] A further improvement is that the vulcanizing machine is a prior art, and other structures are not described in detail here.

[0010] The beneficial effects of the utility model are:

[0011] The utility model provides a vulcanizer feeding device for the production of EVA soles. The feeding device, which is composed of two slide rails, a movable pull plate group, and a support frame, is designed to extend forward longitudinally in the middle of the vulcanizer, and the vulcanized shoe mold is designed to prevent displacement on the movable pull plate group. When the vulcanized shoe mold is being punched, it is pushed forward to the front of the vulcanizer for operation, so that mold opening or die pulling and material removal can be carried out in a relatively wide space, and can also be kept away from the hot pressing plate on the vulcanizer to prevent scalding. When the mold is opened, the top mold on the sole mold is also designed with a clamping seat for tilting and parking, which is convenient for subsequent die pulling and material removal operations.

[0017] In order to make the technical means, creative features, objectives and effects achieved by the present invention easier to understand, the present invention is further described below in conjunction with specific implementation methods.

[0018] See also Figure 1-5The utility model is a schematic diagram of a vulcanizing machine feeding device for EVA sole production. The technical solution is as follows: the structure includes a vulcanizing machine 1, and a feeding device 2 is horizontally arranged in the middle of the vulcanizing machine 1, and the front side of the feeding device 2 extends to the front end of the vulcanizing machine 1. A vulcanized shoe mold 3 is movably placed on the top surface of the feeding device 2. The vulcanizing machine 1 is composed of a frame 11, a cylinder 12, an upper push plate 13 and a heating plate 14. The feeding device 2 includes two slide rails 21, and the two slide rails A movable pull plate group 22 is movably sleeved between the top surfaces 21, and a support frame 23 is provided at the lower end of the front side of the two slide rails 21. The other end of the support frame 23 is fixedly connected to the outside of the front side of the frame 11. The movable pull plate group 22 includes a pull plate 221, and a plurality of sliders 222 are provided on the bottom surfaces of the left and right sides of the pull plate 221, and a plurality of mold positioning columns 223 are vertically provided on the left and right sides of the top surface of the pull plate 221. A card placement seat 224 is provided on the rear end of the top surface of the pull plate 221 at a horizontal and rearward inclination.

[0019] A mold pushing opening 2211 for movably placing the vulcanized shoe mold 3 is opened in the middle of the top surface of the pulling plate 221 , and the opening area of ​​the mold pushing opening 2211 is larger than the area of ​​the upper pushing plate 13 .

[0020] A tapered surface 2231 is formed on the periphery of the upper end of each mold locking column 223 .

[0021] The vulcanized shoe mold 3 includes a sole mold 31, which is composed of a bottom mold and a top mold hingedly covered. Two clamping strips 32 are provided on the left and right sides of the bottom mold of the sole mold 31, and the two clamping strips 32 are provided with clamping holes 33 corresponding to each mold clamping column 223.

[0022] Working principle:

[0023] When in use, first place the vulcanized shoe mold 3 on the push mold opening 2211, and the positioning holes 33 on the two clamping strips 32 are inserted into the respective mold positioning columns 223 in a one-to-one correspondence, so that the vulcanized shoe mold 3 can be positioned on the top surface of the pull plate 221, so that the vulcanized shoe mold 3 is not easily displaced when the vulcanized shoe mold 3 is pulled forward or pushed backward by the movable pull plate group 22. When the vulcanized shoe mold 3 is pushed back to the top of the upper push plate 13, the upper push plate 13 is pushed up by the oil cylinder 12 to pass through the push mold opening 2211. The vulcanized shoe mold 3 is vertically pushed up to contact with the hot pressing plate 14 for heating and vulcanization molding. After completion, the oil cylinder 12 drops back to its original position. At this time, the vulcanized shoe mold 3 will drop back to the mold pushing opening 2211, and the positioning holes 33 on the two positioning strips 32 will be inserted into each mold positioning column 223 in a one-to-one correspondence. The design of the tapered surface 2231 plays a role of automatic fine-tuning and insertion, which can prevent the vulcanized shoe mold 3 from being unable to be automatically inserted due to slight displacement when rising or falling.

[0024] Then, by moving the sliders 222 on the pulling plate group 22, the vulcanized shoe mold 3 is pulled forward to the front of the frame 11 on the two slide rails 21, and then the mold opening operation is carried out. When the sole mold 31 is opened, the top mold will be tilted and parked on the clamping seat 224, and then the vulcanized sole on the bottom mold can be pulled out of the mold. Due to the clamping effect of the clamping hole 33 and the mold clamping column 223, the sole mold 31 will not be displaced when the mold is opened and the mold is pulled out.
