Description

Technical Field

[0001] The utility model relates to the technical field of vulcanization molds, in particular to a mold positioning structure for a vulcanizer and a vulcanizer. Background Technique

[0002] Vulcanization is the last and most important processing step for rubber products. Through a series of complex chemical reactions, rubber is transformed into cross-linked rubber with high elasticity or high hardness, thereby enabling rubber to obtain corresponding mechanical and chemical properties. Unvulcanized rubber is a linear large-structured molecule. When unvulcanized rubber is subjected to external forces, this large-structured molecule will undergo displacement, specifically manifested as obvious deformation of the rubber. After the rubber is vulcanized, its molecular structure forms a network, and the movement of large molecules is restricted. Specifically, vulcanized rubber has better tensile strength and elastic strength than unvulcanized rubber. When vulcanizing rubber products, molds are often required for vulcanization.

[0003] For example, the publication number CN220784579U proposes a mold closing and positioning structure for a flat vulcanizer, including a flat vulcanizer. The inner side wall of the flat vulcanizer is provided with a lower mold plate, the upper surface of the lower mold plate is provided with an upper mold plate, iron sheets are fixedly connected to the four corners of the upper mold plate, the side wall of the iron sheet is adsorbed to the side wall of a magnet, and rubber material is arranged between the inner side walls of the upper mold plate and the lower mold plate. However, during the use of this utility model, only the cooperation of the magnet and the iron sheet is used to position the mold, and it does not have the effect of locking the movable mold. During the processing through the mold, the phenomenon of mold offset is likely to occur, resulting in a gap in the middle of the mold, affecting the production of rubber products.

[0004] Therefore, to solve the above problems, a mold positioning structure for a vulcanizer and a vulcanizer are proposed. Content of the Utility Model

[0007] Among them, the positioning component includes four positioning rods arranged on the lower end face of the upper mold. Four positioning holes are provided on the upper end face of the lower mold. Two cavities are provided inside the lower mold. Two baffles are movably arranged inside the cavities. A limiting rod is arranged on one side of the baffle. A rotating shaft is rotatably arranged inside the cavity. Two ropes are wound around the outer side of the rotating shaft.

[0008] Furthermore, the positioning component further includes a synchronous pulley arranged on the outer side of the rotating shaft. A synchronous belt is arranged in transmission between the two synchronous pulleys. Two springs are arranged inside the cavity.

[0009] Furthermore, four positioning blocks are arranged on the inner side of the middle mold. A positioning through hole adapted to the size of the positioning rod is provided inside the positioning block.

[0010] Furthermore, an annular groove is provided on the outer side of the positioning rod. One side of the limiting rod is an inclined surface.

[0011] Furthermore, one end of the spring is fixedly connected to the side of the baffle away from the limiting rod.

[0012] Furthermore, one end of the rope is fixedly connected to the baffle. A pulling plate is arranged at the other end of the rope. One end of the rope penetrates and extends to the outside of the lower mold.

[0013] Furthermore, one end of the rotating shaft penetrates and extends to the outside of the lower mold. The synchronous pulley is arranged on the outside of the lower mold.

[0014] Furthermore, one end of the limiting rod penetrates and extends into the positioning hole. The positioning hole is adapted to the width of the positioning rod.

[0015] Compared with the prior art, the technical solution of the present application has the following beneficial effects:

Specific implementation manner

[0024] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without making creative efforts shall fall within the protection scope of the present utility model.

[0025] Please refer to Figures 1-5 , a mold positioning structure and a vulcanizer for a vulcanizer in this embodiment include a vulcanizer body 1, a mold structure is arranged on the vulcanizer body 1, the mold structure includes a lower die 2, a middle die 3 and an upper die 4, and a positioning component is arranged on the lower die 2;

[0026] Among them, the positioning component includes four positioning rods 11 arranged on the lower end surface of the upper die 4, four positioning blocks 10 are arranged inside the middle die 3, a positioning through hole adapted to the size of the positioning rod 11 is opened inside the positioning block 10, and four positioning holes 5 are opened on the upper end surface of the lower die 2, and the positioning holes 5 are adapted to the width of the positioning rod 11.

[0027] During actual use, by connecting the positioning rods 11 with the positioning through holes on the positioning blocks 10 and the positioning holes 5 opened on the lower die 2 respectively, the positioning of the lower die 2 and the middle die 3 can be realized, and the situation of offset of the lower die 2, the middle die 3 and the upper die 4 can be reduced.

[0028] Please refer to Figures 2-5Two cavities 12 are provided inside the lower mold 2, and two baffles 14 are movably provided inside the cavity 12. A limiting rod 13 is provided on one side of the baffle 14, and one end of the limiting rod 13 passes through and extends to the inside of the positioning hole 5. A rotating shaft 7 is rotatably provided inside the cavity 12, and two pull ropes 15 are wound around the outside of the rotating shaft 7.

[0029] In addition, an annular groove is provided on the outside of the positioning rod 11, one side of the limiting rod 13 is a slope, one end of the pull rope 15 is fixedly connected to the baffle 14, and the other end of the pull rope 15 is provided with a pull plate 6. One end of the pull rope 15 passes through and extends to the outside of the lower mold 2.

[0030] During actual use, the limiting rod 13 is connected to the annular groove opened on the outside of the positioning rod 11, so that the limiting rod 13 can limit the positioning rod 11 and limit the movement of the positioning rod 11, thereby achieving the effect of positioning and locking the lower mold 2, the middle mold 3 and the upper mold 4, so that it is not easy for the molds to loosen and shift or leave gaps in the middle.

[0031] It should be noted that by pulling the pull plate 6 to move the pull rope 15, the other end of the pull rope 15 can pull the limit rod 13 to move, so that the limit rod 13 is disengaged from the annular groove opened on the positioning rod 11, thereby removing the restriction on the positioning rod 11.

[0032] See also Figures 2-5 The positioning assembly further includes a synchronous wheel 8 arranged on the outside of the rotating shaft 7, a synchronous belt 9 is provided between the two synchronous wheels 8, and two springs 16 are provided inside the cavity 12.

[0033] One end of the rotating shaft 7 passes through and extends to the outside of the lower mold 2 , the synchronous wheel 8 is arranged on the outside of the lower mold 2 , and one end of the spring 16 is fixedly connected to the side of the baffle 14 away from the limiting rod 13 .

[0034] During actual use, through the setting of the spring 16, after the limit rod 13 moves, the elastic force of the spring 16 can drive the limit rod 13 to reset, and through the setting of the synchronous wheel 8 and the synchronous belt 9, when one of the pull plates 6 is pulled to drive the pull rope 15 to move, the four limit rods 13 can all move, so that the four limit rods 13 can respectively cancel the restrictions on the four positioning rods 11, which is convenient for canceling the restrictions on each mold and facilitating the subsequent removal of the vulcanized product.

[0035] The working principle of the above embodiment is:

[0036] When vulcanizing and processing through the cooperation of the vulcanizer body 1 and the mold, the product to be vulcanized is placed into the middle mold 3, then the middle mold 3 is placed on the lower mold 2, and then the upper mold 4 is driven to move downward. During the movement of the upper mold 4, the positioning rods 11 are respectively connected with the positioning through holes on the positioning blocks 10 and the positioning holes 5 opened on the lower mold 2 to position the lower mold 2 and the middle mold 3. During the fitting process of the lower mold 2, the middle mold 3 and the upper mold 4, the positioning rods 11 move to squeeze the inclined surfaces of the limiting rods 13, causing the limiting rods 13 to retract. When the positioning rods 11 are connected with the positioning holes 5, the elastic force of the spring 16 drives the limiting rods 13 to reset, and the limiting rods 13 limit the positioning rods 11 to position and lock the lower mold 2, the middle mold 3 and the upper mold 4, so that it is not easy for the molds to loosen, shift or have gaps in the middle, which is convenient for the vulcanizer body 1 to vulcanize the product and improves the quality of product production. When the product vulcanization is completed, by pulling one of the pull plates 6, the pull plate 6 drives the pull rope 15 to rotate around the rotating shaft 7, so that one end of the pull rope 15 pulls the limiting rod 13 to move, canceling the limitation of the limiting rod 13 on the positioning rod 11. During the rotation of the rotating shaft 7, through the setting of the synchronous pulley 8 and the synchronous belt 9, the other rotating shaft 7 rotates accordingly, and then the four limiting rods 13 can be driven to move, respectively canceling the limitation of the four limiting rods 13 on the four positioning rods 11, facilitating the cancellation of the limitation on each mold and convenient for taking out the vulcanized product subsequently.
