Abstract
The triangular die comprises a lower die, an upper die, a middle frame and a last, wherein the middle frame comprises a right middle frame and a left middle frame, the last is fixed on a last die holder, the last die holder is fixed in a clamping groove in the middle of the lower die through a right pressing plate and a left pressing plate, the right middle frame and the left middle frame are respectively arranged at the top of the right pressing plate and the top of the left pressing plate, the upper die is provided with a U-shaped groove structure, and a sole model is arranged in the middle of the upper die. The utility model realizes one-time compression molding of the sole and the vamp through the in-mold integrated molding structure, avoids the differentiation problem of manual bottom assembly, reduces the rejection rate in the production process, and ensures that the sole and the vamp have strong bonding force and no adhesive opening risk through the integrated molding process; the production process is simple, the labor cost is low, and the energy is saved and the environment is protected; the standardized production of the sole can be realized.
Description
Technical Field
The utility model relates to a shoemaking processing technology field, concretely relates to triangle mould.
Background
The shoes generally comprise soles and uppers, and are foot wear with the functions of protection and decoration. The sole portion and the upper portion are typically made of separate materials and then joined together by machine stitching, glue bonding, injection molding or mold curing. The manufacturing method needs more procedures, consumes manpower and material resources, can generate more environmental pollutants, and can not be repeatedly used due to more materials in the production process, thereby causing resource waste. And the shoe manufactured by the connecting method has the advantages that the sole and the vamp are easy to separate or seep water.
SUMMERY OF THE UTILITY MODEL
The utility model provides a triangle mould to the not enough of prior art existence.
The utility model provides a technical scheme that its technical problem adopted is:
a triangular die comprises a lower die, an upper die, a middle frame and a last, wherein the middle frame comprises a right middle frame and a left middle frame, the last is fixed on a last die holder, the last die holder is fixed in a clamping groove in the middle of the lower die through a right pressing plate and a left pressing plate, the right middle frame and the left middle frame are respectively arranged at the top of the right pressing plate and the top of the left pressing plate, the upper die is provided with a U-shaped groove structure, and a sole model is arranged in the middle of the upper die.
The utility model discloses during the use of triangular mold mould, at first fix last 5 on last mould is 6, push into the mould in the draw-in groove that forms between left and right sides clamp plate 7 and 8, fold middle frame 3 and middle frame 4 by hand, put into raw rubber material in the die cavity that forms between middle frame 3 and middle frame 4, it can the downstream to go up mould 2 at board upper plate hydraulic pressure effort at this time, because the inclination design of middle frame 3 and middle frame 4 both sides, it can form a horizontally compound die effort to go up mould 2 to right middle frame 3 and left middle frame 4, make right frame 3 and left side frame 4 tightly clip the vamp of heating, raw rubber material vulcanizes the shaping under the condition of board, because vamp and last have been cliied to right frame 3 and left side frame 4, an inclosed space has been formed, just so can avoid rubber materials can not spill over the mould when the high temperature vulcanizes.
The utility model realizes one-time compression molding of the sole and the vamp through the in-mold integrated molding structure, avoids the differentiation problem of manual sole assembly, reduces the rejection rate in the production process, and ensures that the sole and the vamp have strong bonding force and no adhesive failure risk through the integrated molding process; the production process is simple, the labor cost is low, and the energy is saved and the environment is protected; the standardized production of the sole can be realized.
Description of the drawings:
the present invention will be further described with reference to the accompanying drawings and examples.
Fig. 1 is a schematic cross-sectional view of the present invention;
fig. 2 is a schematic structural diagram of the present invention.
In the figure, 1, a lower die, 2, 3, a right middle frame, 4, a left middle frame, 5, 6, a last die holder, 7, a right press plate and 8, a left press plate.
The specific implementation mode is as follows:
as shown in fig. 1 and 2, a triangular mold is composed of a lower mold 1, an upper mold 2, a middle frame and a last 5, wherein the middle frame comprises a right middle frame 3 and a left middle frame 4, the last 5 is fixed on the last mold base 6, the last mold base 6 is fixed in a clamping groove in the middle of the lower mold 1 through a right pressing plate 7 and a left pressing plate 8, the right middle frame 3 and the left middle frame 4 are respectively arranged on the top of the right pressing plate 7 and the top of the left pressing plate 8, the upper mold 2 is of a U-shaped groove structure, a sole model is arranged in the middle of the upper mold 2, in practical application, the last 5 is fixed on the last mold 6 firstly, the last 5 is pushed into the mold along the clamping groove formed between the left pressing plate 7 and the right pressing plate 8, the middle frame 3 and the middle frame 4 are manually folded, raw rubber is placed in a mold cavity formed between the middle frame 3 and the middle frame 4, the upper mold 2 moves downwards under the hydraulic action force of the upper plate at this time, and due to the slope design of the two sides of the middle frame 3 and the middle frame 4, the upper mold can tightly clamp the right middle frame 3 and the left frame 4, and the left frame, and the vulcanizing machine table can not clamp the left frame 3, and the left frame 4, and the vulcanizing machine table to form a vulcanizing machine, and a rubber frame, and a closed space, and a vulcanizing machine table can be prevented from overflowing under the vulcanizing machine, and a high-side frame, and a machine table from overflowing under the vulcanizing machine, and a rubber forming condition.
The utility model realizes one-time compression molding of the sole and the vamp through the in-mold integrated molding structure, avoids the differentiation problem of manual bottom assembly, reduces the rejection rate in the production process, and ensures that the sole and the vamp have strong bonding force and no adhesive opening risk through the integrated molding process; the production process is simple, the labor cost is low, and the energy is saved and the environment is protected; the standardized production of the sole can be realized.
