Description

Technical Field

[0001] The utility model belongs to the technical field of vulcanization molds, and particularly relates to a batch production mold for a skeleton belt. Background Art

[0002] For the vulcanization production of traditional belt products, the belt itself is first produced without vulcanizing with a skeleton. After the product is demolded, the skeleton is assembled, which increases the production process of the product, prolongs the delivery period, and also increases the production cost of the product.

[0003] Moreover, when designing traditional molds, a flash groove is opened at a position 0.3 mm away from the cavity in the upper and lower molds, a waste material groove is opened at a position 1 mm away from the flash groove in the lower mold, and a bearing surface is opened at a position 5 mm away from the waste material groove. In addition to considering the unit consumption of the product cavity during production, this type of structure also has to take into account the flash groove and the waste material groove at the same time. If the rubber material cannot fill the flash groove and the waste material groove, the flash will not be full during deburring, resulting in incomplete deburring in one go and reducing work efficiency. Content of the Utility Model

Upper cavities and lower cavities are respectively arranged at one ends of the upper frame and the lower frame facing the lifting frame. A cross beam is installed in the middle of the lifting frame. The upper cavity, the lower cavity, and the cross beam together form a belt cavity. A plurality of groups of skeleton mounting blocks are installed on both sides of the cross beam in the direction towards the upper frame. Both the upper cavity and the lower cavity include a plurality of groups of belt grooves, and the belt grooves correspond to the skeleton mounting blocks one by one;

[0007] The skeleton mounting block is a mountain-shaped raised block with two groups of skeleton mounting grooves, and the skeleton mounting block is detachably installed with a skeleton;

[0008] The lower cavity also includes a flash groove, the flash groove is located outside the contour of the belt groove, and the depth of the belt groove is greater than that of the flash groove.

[0009] As a preferred technical solution, the distance between any two adjacent groups of skeleton mounting blocks along the length direction of the cross beam is equal.

[0010] As a preferred technical solution, the middle parts of the upper cavity and the lower cavity respectively include cross beam grooves for accommodating the cross beam. When the upper frame contacts the lifting frame, the cross beam contacts and connects with the inner wall of the cross beam groove. When the lower frame contacts the lifting frame, the cross beam contacts and connects with the inner wall of the cross beam groove.

[0011] As a preferred technical solution, the upper frame and the lower frame are respectively provided with an upper mounting film and a lower mounting mold protruding towards the lifting frame. The upper cavity is opened on the upper mounting film, and the lower cavity is opened on the lower mounting mold.

[0012] As a preferred technical solution, a set of fixing columns is installed between any two adjacent sets of watchband grooves along the length direction of the crossbeam. Two insertion holes are opened on one side of the lower mounting mold. The two insertion holes are respectively located on both sides of the crossbeam, and the insertion hole on one side penetrates through all the fixing columns on the same side. The axes of the two insertion holes are parallel to the length direction of the crossbeam. A plug rod is detachably inserted into the insertion hole, and the plug rod penetrates through the end of the watchband groove on the same side away from the crossbeam.

[0013] As a preferred technical solution, a plurality of watch hole columns are arranged within the range corresponding to each set of watchband grooves in the lower cavity. When the upper frame and the lifting frame are in contact, the watch hole columns are in contact connection with the upper cavity.

[0014] As a preferred technical solution, mounting grooves are opened on the inner walls of both sides of the lifting frame along the length direction of the crossbeam. The opening direction of the mounting groove faces the upper frame and the crossbeam. The length direction of the mounting groove is perpendicular to the length direction of the crossbeam. A pressing block is installed in the mounting groove. The length direction of the pressing block is consistent with the length direction of the mounting groove.

When the lifting frame and the lower frame are in contact, the positioning pins correspondingly penetrate and are inserted into the positioning holes.

[0016] The advantages of the present utility model are as follows: This mold vulcanizes with a skeleton. During vulcanization, the rubber material directly wraps the skeleton. After production, there is no need for additional assembly of the skeleton, reducing the production process of the product and lowering the production cost; Since the depth of the flash groove is extremely small, the flash after vulcanization is uniform and extremely thin. It only needs to fill the product into a freezer for deburring, with high production efficiency and greatly reducing the labor cost.

[0033] The upper cavity 5 and the lower cavity 8 both include multiple groups of watchband grooves 11. The lower cavity 8 further includes a flash groove 10. The flash groove 10 is located outside the contour of the watchband grooves 11. The watchband grooves 11 correspond to the skeleton mounting blocks 62 one by one. The depth of the watchband grooves 11 is greater than that of the flash groove 10. Within the range corresponding to each group of watchband grooves 11 in the lower cavity 8, multiple groups of watch hole columns 9 are provided. When the upper frame 1 and the lifting frame 2 are in contact, the watch hole columns 9 are in contact and connected with the upper cavity 5. In the middle parts of the upper cavity 5 and the lower cavity 8, cross beam grooves 12 for accommodating the cross beam 6 are correspondingly included.

[0036] A plurality of sets of guide rods and guide grooves are provided between the upper frame 1 and the lower frame 3 and the lifting frame 2. The guide rods and guide grooves are used to accurately contact and install the lifting frame 2 with the upper frame 1 and the lower frame 3 respectively.

[0037] Production process:

[0038] S1: Install the skeletons 13 on the skeleton mounting blocks 62 on both sides of the cross beam 6 one by one. After installation, place the cross beam 6 into the installation groove 21, and push the cross beam 6 so that the cross beam 6 is clamped between the pressing block 22 and the inner wall of the installation groove 21 to fix the cross beam 6;

[0039] S2: Lower the lifting frame 2, and the positioning pins 81 are correspondingly inserted into the positioning holes 63 on the cross beam 6 until the lifting frame 2 contacts the lower frame 3;

[0040] S3: Insert the two groups of inserting rods 16 into the inserting holes 15 on both sides respectively. The inserting rods 16 are used to produce the installation holes for facilitating the installation and fixation of the watch band fixing parts;

[0041] S4: Place the rubber materials on the watch hole columns 9 in the watch band grooves 11 one by one. The watch hole columns 9 are used to produce the positioning holes on the watch band;

[0042] S5: Lower the upper frame 1 until the upper frame 1 contacts the lifting frame 2;

[0043] S6: After vulcanization production, move out the whole, raise the upper frame 1, and take out the inserting rods 16;

[0044] S7: Raise the lifting frame 2, and the produced watch bands move up with the cross beam 6. Take out the cross beam 6 in the opposite direction of the installation direction, and at the same time take out all the watch bands, and take out the watch bands from the skeleton mounting blocks 62;

[0045] S8: Send the watch bands with flash to the freezer for deburring.

[0046] This mold vulcanizes with the skeleton 13. During vulcanization, the rubber material directly wraps the skeleton 13. After production, no additional assembly of the skeleton is required, reducing the production process of the product and lowering the production cost; since the depth of the flash groove 10 is extremely small, the flash after vulcanization is uniform and extremely thin. Just fill the product into the freezer for deburring, with high production efficiency and greatly reducing the labor cost.
