Description

TECHNICAL FIELD

[0001] The utility model relates to a forming die, in particular to a die for rubber sole forming. BACKGROUND

[0002] The process of rubber sole processing involves its forming, and the current stamping forming mode is usually adopted to construct the basic shape and cavity structure of the rubber sole. At present, the die for rubber sole forming needs to use a mechanical structure to take out the formed rubber sole after the forming work is completed. In the process of contact, positioning and movement of the mechanical structure and the rubber sole, the shape of the rubber sole is inevitably affected, which causes its deformation and reduces the quality of the rubber sole. SUMMARY

[0003] The utility model discloses a die for rubber sole forming, which avoids using a mechanical structure to operate when taking out the rubber sole, is beneficial to maintaining the shape of the rubber sole, and thus improves the quality of rubber sole processing.

[0004] To achieve the above object, the utility model provides the following technical scheme: a die for rubber sole forming, which comprises a base, a lower die seat fixed to the upper end face of the base and a forming assembly arranged above the base. The lower die seat is a cavity structure with an opening in the upper end face and a hollow inside. The forming assembly comprises a driving facility and an upper die seat fixedly connected to the output end of the driving facility. The upper die seat is located directly above the lower die seat, and the cavity structure of the upper die seat is adapted to the cavity structure of the lower die seat, so that the upper die seat can be inserted into the lower die seat in a matching manner and perform stamping forming processing on the rubber sole in the lower die seat. A through assembly and a blowing assembly are further arranged on the base. The through assembly comprises a first air cylinder arranged below the base, a lifting frame fixedly connected to the output end of the first air cylinder and a sliding rod fixedly connected to the upper end face of the lifting frame. The through assembly further comprises a second air cylinder arranged outside the lower die seat, a socket connected to the output end of the second air cylinder and a fitting plate located in the cavity of the lower die seat. The socket slides through the lower die seat and is fixedly connected to the fitting plate, so that the socket drives the fitting plate to move.

[0005] Preferably, airflow discharge grooves are arranged on both sides of the cavity of the lower die seat, and the two fitting plates are located in the two airflow discharge grooves respectively. When the two fitting plates move to appropriate positions, they can just contact the rubber sole in the cavity of the lower die seat, so that a complete forming groove is formed in the cavity structure of the lower die seat.

[0006] Preferably, the driving facility is installed on a top seat, and the top seat is fixed to the upper end face of the base. In this way, the driving facility and the upper die seat can both maintain stable structures.

[0007] Preferably, a fixed seat is fixed to the lower end face of the base, and the first air cylinder is installed on the lower end face of the fixed seat. In this way, the structure of the first air cylinder can be kept stable.

[0008] Preferably, there are two sliding bars, and the two sliding bars are located on both sides of the upper end face of the lifting frame.

[0009] Preferably, two ventilation grooves are formed on the lower end face of the base, extending into the lower mold base, and two slide bars are respectively inserted into the two ventilation grooves.

[0010] Preferably, side supports are fixed on both sides of the lower mold base, and two second cylinders are provided, with the two second cylinders respectively installed on the two side supports; so that the structure of the two second cylinders remains stable.

[0011] Preferably, both sockets pass through the lower mold base in a horizontal direction, and one end of each socket enters the cavity structure of the lower mold base; this allows the position of the two bonding plates to be adjusted when the two sockets slide.

[0012] Preferably, the blower assembly includes a blower fixed to the lower end face of the base and an air supply pipe connected to the blower. An air outlet channel is provided inside the base. The openings on both sides of the air outlet channel are respectively connected to the air supply pipe and the air vent, so as to facilitate the high-speed airflow delivered by the air supply pipe to be sent to the lower mold base through the air vent, and the rubber shoe sole is slowly pushed out by the airflow.

[0013] Compared with the prior art, the beneficial effects of this utility model are as follows: After the molding component completes the molding of the rubber sole, the first cylinder moves the two slide bars downward, making the two air outlet channels communicate with the cavity of the lower mold base. The two second cylinders open the air discharge slots on both sides of the lower mold base. At this time, the two blowers can run to ventilate the gap between the lower mold base and the rubber sole, and the air can be quickly discharged through the air discharge slots, thereby gradually separating the lower mold base from the rubber sole for easy removal. Compared with the traditional solution that uses a mechanical structure to directly push out the rubber sole, this solution has less impact on the shape of the rubber sole, which is conducive to maintaining the shape of the rubber sole and thus improving the quality of rubber sole processing.

[0025] Please refer to Figure 5Airflow discharge grooves 21 are provided on both sides of the cavity of the lower mold base 2. Two bonding plates 49 are located in the two airflow discharge grooves 21 respectively. When the two bonding plates 49 move to the appropriate position, they can just contact the rubber shoe sole in the cavity of the lower mold base 2, thereby forming a complete molding groove in the cavity structure of the lower mold base 2.

[0026] In this invention, the rubber sole to be formed is first placed in the lower mold base 2. Then, the two second cylinders 47 operate, moving the two bonding plates 49 to a designated position so that the two bonding plates 49 are in contact with the rubber sole, avoiding gaps. The drive mechanism 32 then operates, and the upper mold base 33 enters the lower mold base 2 to complete the stamping of the rubber sole. Subsequently, the upper mold base 33 returns to its original position (separating from the lower mold base 2), and the first cylinder 42 operates, causing the lifting frame 43 to descend, causing the two sliding rods 44 to descend to the attached position. Figure 4 In the state shown, the two second cylinders 47 operate, causing the two sockets 48 to move away from each other, and the two bonding plates 49 to move away from each other. At this time, a certain gap is left between the two airflow discharge slots 21 and the rubber sole. Then, the two blowers 51 are driven to run, so that the two air supply pipes 52 send high-speed airflow into the two air outlet channels 53, and then enter the lower mold base 2 through the two air vents 45. This causes the high-speed airflow to slowly blow the rubber sole upward, causing the lower mold base 2 to slowly separate from the rubber sole. The high-speed airflow can be quickly discharged through the two airflow discharge slots 21, which is conducive to the rapid separation of the rubber sole from the lower mold base 2. In this way, the use of mechanical structures can be avoided when separating the rubber sole, so the impact on the shape of the rubber sole is minimal, thus protecting the shape of the rubber sole.

Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description.
