Technical Field

[0001] The utility model belongs to the technical field of safety shoe production and relates to a forming mold, in particular to a forming mold for a safety shoe head. Background Art

[0002] Safety shoes refer to shoes worn in different working situations that protect the feet and legs from foreseeable injuries. They are high-tech and high-value-added footwear products. The production process of safety shoes has very high requirements on raw materials, auxiliary materials, chemicals, mechanical equipment, etc.

[0003] After searching, it is found that a Chinese patent document discloses an injection molding mold for the production of safety shoes [Application number: 202220948822.2; Publication number: CN 217414796 U]. This injection molding mold for the production of safety shoes belongs to the technical field of safety shoe production, and includes a base, a water tank, a lower mold, a stripper, an upper mold and a top plate are arranged on the upper side of the base in sequence, a driving component is arranged on the top plate, and the driving component is used to drive the upper mold and the stripper to move up and down, a cavity is arranged in the lower mold, cooling water is stored in the water tank, and a cooling component is arranged between the water tank and the lower mold, and the cooling component is used to cool the lower mold; it can quickly demold, reduce manual operation, and speed up demolding efficiency. The lower mold and the upper mold can be quickly cooled to avoid scalding, effectively speeding up the mold forming speed and improving production efficiency.

[0004] Although the cooling assembly disclosed in this patent can quickly demold, reduce manual operations, and speed up demolding efficiency, the lower mold and the upper mold can be quickly cooled to avoid burns, effectively speed up the mold forming speed, and improve production efficiency. However, after injection molding, the toe will fit onto the inner wall of the mold, requiring staff to manually pry it out of the finished product, reducing work efficiency. Utility Model Content

[0005] The purpose of the utility model is to solve the above problems in the existing technology and to propose a safety shoe toe molding mold. The technical problem to be solved by the utility model is: how to conveniently and directly take out the finished shoe toe stuck to the inner wall of the mold after the shoe toe is cooled and molded.

[0006] The purpose of the utility model can be achieved through the following technical solutions:

[0015] The upper end surface of the separation column is arc-shaped, and the separation column fits the inner wall of the arc-shaped groove.

[0016] By adopting the above structure and installing the separation column, when the semicircular block presses down the separation column on the long rod, the separation column just fits against the inner wall of the arc groove, avoiding affecting the appearance quality of the finished product, and at the same time will not cause damage to the finished product when separating the finished product from the mold.

[0017] Compared with the prior art, the molding die of the safety shoe toe has the following advantages:

[0018] 1. The two molds slide in corresponding directions. After the two molds are combined together, the arc grooves are spliced ​​into a semicircle. The cylinder is started, and the telescopic end of the cylinder pushes mold two downward until the semicircular block on mold two extends into the arc groove composed of two arc grooves. The partition separates the two arc grooves, so that two toe products can be formed at one time, which improves work efficiency. The raw material is then injected into the gap between the arc groove and the semicircular block through the injection mechanism. When the raw material is cooled and formed, the finished product in the arc groove is squeezed out of the arc groove through the separation mechanism to avoid the finished product sticking to the inner wall of mold one, which is convenient for direct removal.

[0019] 2. By installing the spring and the long rod, when the cylinder drives the mold 2 to press down, the mold 2 contacts the telescopic block, applies pressure to the telescopic block and shrinks it into the installation groove. When the toe cap in the mold 1 is cooled and formed, the mold 2 leaves the mold 1. Through the elastic force of the spring, the telescopic block drives the long rod to extend upward, and one end of the long rod extending into the arc groove bounces up, squeezing the finished product out of the arc groove, making it convenient to take the finished toe cap and preventing the finished toe cap from sticking to the inner wall of the arc groove.

[0026] The working principle of the utility model is as follows: two molds 2 slide in corresponding directions. After the two molds 2 are combined together, the arc grooves 3 are spliced ​​into a semicircle. The cylinder 5 is started, and the telescopic end of the cylinder 5 pushes the mold 2 6 downward until the semicircular block 7 on the mold 2 6 extends into the arc groove 3 composed of the two arc grooves 3. The partition plate 18 separates the two arc grooves 3, so that two toe products are formed at one time, which improves the work efficiency. Then, the raw material is injected into the gap between the arc groove 3 and the semicircular block 7 through the injection mechanism. When the raw material is cooled and formed, the finished product in the arc groove 3 is squeezed out of the arc groove 3 through the separation mechanism to avoid the finished product sticking to the inner wall of the mold 2, so that it is convenient to take it out directly.

[0029] The separation mechanism includes a mounting groove 12 opened on the mold 2, the mounting groove 12 is connected to the arc groove 3, a plurality of springs 13 are fixed in the mounting groove 12, a telescopic block 14 extending out of the mounting groove 12 is slidably connected in the mounting groove 12, the other end of the spring 13 is fixedly connected to the telescopic block 14, a long rod 15 is fixed at the lower end of the telescopic block 14, and a separation column extending into the arc groove 3 is fixed at the other end of the long rod 15.

[0030] With the above structure, by installing the spring 13 and the long rod 15, when the cylinder 5 drives the mold 2 6 to press down, the mold 2 6 contacts the telescopic block 14, and applies pressure to the telescopic block 14 to shrink it into the installation groove 12. When the toe cap in the mold 1 2 is cooled and formed, the mold 2 6 leaves the mold 1 2. Through the elastic force of the spring 13, the telescopic block 14 drives the long rod 15 to extend upward, and one end of the long rod 15 extending into the arc groove 3 bounces up, squeezing the finished product out of the arc groove 3, thereby making it convenient to take the finished toe cap and preventing the finished toe cap from sticking to the inner wall of the arc groove 3.

[0035] The working principle of the utility model is as follows: the motor 9 is started to drive the bidirectional threaded rod 10 to rotate, the slider 11 drives the two molds 2 to move in the corresponding direction, and after the two molds 2 are combined together, the arc grooves 3 are spliced ​​into a semicircle, the cylinder 5 is started, and the telescopic end of the cylinder 5 pushes the mold 2 6 downward until the semicircular block 7 on the mold 2 6 extends into the semicircular groove composed of the two arc grooves 3, and the partition 18 separates the two arc grooves 3. At the same time, the mold 2 6 contacts the telescopic block 14, which is on the telescopic block 14 and the long rod 15. The separation column 19 is retracted into the installation groove 12 under pressure, and the separation column 19 on the long rod 15 fits with the inner wall of the arc groove 3. The raw material in the storage box 16 is drawn into the gap between the arc groove of the mold 2 and the semicircular block 7 through the plastic tube 17. When the raw material is cooled and formed, the mold 2 6 leaves the mold 1 2. Through the elastic force of the spring 13, the telescopic block 14 drives the long rod 15 to extend upward.
