Description

Technical Field

[0001] This utility model relates to the technical field of shoe upper hot press machines, specifically a shoe upper hot press machine with multiple molds. Background Technology

[0002] Hot pressing of shoe uppers is a thermoplastic processing technology that uses high temperature and pressure to heat and deform shoe upper materials through a mold to form the desired shape. Compared with traditional manual processing and automated production methods, this process has higher processing efficiency and better consistency.

[0003] The existing shoe upper hot press machines have poor applicability and cannot operate multiple mold seats simultaneously or a single mold seat independently, which reduces the shoe upper processing efficiency and cannot perform multiple hot presses on the shoe upper according to usage requirements, thus failing to meet usage needs.

[0004] Therefore, it is necessary to provide a shoe upper hot press with multiple molds to solve the above-mentioned technical problems. The information disclosed in this background section is only intended to enhance the understanding of the overall background of this utility model, and is not necessarily to be regarded as an admission or to imply in any way that the information constitutes prior art known to those skilled in the art. Utility Model Content

[0005] The purpose of this invention is to provide a shoe upper hot press with multiple molds to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution:

[0007] A shoe upper hot press with multiple molds includes a base, a fixed seat mounted on the top of the base, an mounting plate mounted on the top of the fixed seat, a frame mounted on the top of the mounting plate, a cylinder mounted on the top of the frame, a stamping plate mounted on the bottom of the cylinder through a piston rod penetrating the inner cavity of the frame, upper stamping dies arranged around the bottom of the stamping plate, lower stamping dies used in conjunction with the upper stamping dies mounted around the bottom of the inner cavity of the frame, a hydraulic cylinder mounted around the top of the stamping plate, a buffer plate mounted on the bottom of the hydraulic cylinder through a piston rod penetrating the bottom of the stamping plate, and buffer springs mounted around the bottom of the buffer plate, the bottom of the buffer springs being fixed to the top of the upper stamping dies.

[0008] Preferably, slide bars are installed on both sides of the top of the stamping plate, and the top of the slide bars extends through both sides of the top of the frame and is fitted with limit blocks.

[0009] Preferably, a pressure spring is sleeved on the bottom of the slide bar surface, the top of the pressure spring is fixed to both sides of the top of the inner cavity of the frame, and the top of the pressure spring is fixed to the top of the stamping plate.

[0010] Preferably, the base is provided with support feet around its bottom, and the bottom of the support feet is provided with anti-slip pads.

[0011] Preferably, both sides of the top of the inner cavity of the frame are provided with through slots for use with the slide rod.

[0012] Preferably, there are four hydraulic cylinders and four stamping dies, and the four are evenly distributed around the top and bottom of the buffer plate.

[0013] Compared with the prior art, the beneficial effects of this utility model are as follows: by setting multiple upper and lower stamping dies, multiple shoe uppers can be hot-pressed. The cylinder drives the stamping plate to move downward, and the stamping plate drives the upper stamping die and the buffer plate to move downward. The upper stamping die hot-presses the shoe upper below. The force applied to the upper stamping die can be offset and absorbed by the buffer spring. Through the above steps, four or more shoe uppers added later can be hot-pressed. When one or more shoe uppers need to be hot-pressed individually, the hydraulic cylinder can be activated separately. The hydraulic cylinder drives the upper stamping die to hot-press the shoe upper below through the buffer plate and the buffer spring. Attached Figure Description

[0019] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0020] Please see Figure 1-4 This utility model provides a technical solution for a shoe upper hot press machine with multiple molds: it includes a base 1, a fixed seat 2 installed on the top of the base 1, an mounting plate 3 installed on the top of the fixed seat 2, a frame 4 installed on the top of the mounting plate 3, a cylinder 5 installed on the top of the frame 4, a stamping plate 6 installed at the bottom of the cylinder 5 through a piston rod penetrating the inner cavity of the frame 4, an upper stamping mold 7 arranged around the bottom of the stamping plate 6, a lower stamping mold 8 used in conjunction with the upper stamping mold 7 installed around the bottom of the inner cavity of the frame 4, a hydraulic cylinder 9 installed around the top of the stamping plate 6, a buffer plate 10 installed at the bottom of the hydraulic cylinder 9 through a piston rod penetrating the bottom of the stamping plate 6, and a buffer spring 11 installed around the bottom of the buffer plate 10, the bottom of the buffer spring 11 being fixed to the top of the upper stamping mold 7.

[0021] Furthermore, slide rods 12 are installed on both sides of the top of the stamping plate 6. The top of the slide rods 12 passes through both sides of the top of the frame 4 and is equipped with limit blocks. First, the shoe upper is fixed on the stamping die 8, and then the cylinder 5 is started. The cylinder 5 drives the stamping plate 6 to move downward, and the stamping plate 6 drives the inner cavity of the frame 4 of the slide rod 12 to slide, which increases the stability of the stamping plate 6 when it moves.

[0022] Furthermore, a pressure spring 13 is fitted on the bottom of the surface of the slide bar 12. The top of the pressure spring 13 is fixed to both sides of the top of the inner cavity of the frame 4. The top of the pressure spring 13 is fixed to the top of the stamping plate 6. The stamping plate 6 drives the stamping upper die 7 and the buffer plate 10 to move downward. The stamping upper die 7 performs hot pressing on the shoe upper below. The force applied to the stamping upper die 7 can be offset and absorbed by the buffer spring 11. Through the above steps, the four or more shoe uppers added later can be hot pressed.

[0023] Furthermore, support feet are installed around the bottom of the base 1, and anti-slip pads are installed on the bottom of the support feet. When one or more shoe uppers need to be heat-pressed individually, the hydraulic cylinder 9 can be activated individually. The hydraulic cylinder 9 drives the upper stamping die 7 to heat-press the shoe upper below through the buffer plate 10 and the buffer spring 11.

[0024] Furthermore, both sides of the top of the inner cavity of the frame 4 are provided with through slots that cooperate with the slide bar 12. The buffer spring 11 can effectively absorb and reduce the impact force generated during the stamping process, maintain the stable operation of the equipment, and thus improve the stability of the production process.

[0025] Furthermore, there are four hydraulic cylinders 9 and four upper stamping dies 7, which are evenly distributed around the top and bottom of the buffer plate 10. With the setting of the pressure spring 13, when the slide rod 12 drives the upper stamping die 7 through the stamping plate 6 during the rapid opening and closing of the mold, it can help the upper stamping die 7 to quickly return to its original position, shorten the downtime of the equipment, and improve production efficiency.

[0026] It should be noted that this utility model is a shoe upper hot press machine with multiple molds. First, the shoe upper is fixed on the lower stamping mold 8. Then, the cylinder 5 is started, which drives the stamping plate 6 to move downward. The stamping plate 6 drives the inner cavity of the frame 4 of the slide rod 12 to slide, which increases the stability of the stamping plate 6 when moving. The stamping plate 6 drives the upper stamping mold 7 and the buffer plate 10 to move downward, and the upper stamping mold 7 performs hot pressing on the shoe upper below. The force applied to the upper stamping mold 7 can be offset and absorbed by the buffer spring 11. Through the above steps, the machine can process four or more molds below, or multiple molds added later. The shoe upper undergoes hot pressing. When one or more shoe uppers need to be hot pressed individually, the hydraulic cylinder 9 can be activated separately. The hydraulic cylinder 9 drives the upper stamping die 7 to hot press the shoe upper below through the buffer plate 10 and the buffer spring 11. The buffer spring 11 can effectively absorb and reduce the impact force generated during the stamping process, maintain stable operation of the equipment, and thus improve the stability of the production process. Through the setting of the pressure spring 13, when the slide rod 12 drives the upper stamping die 7 through the stamping plate 6 during the rapid opening and closing of the mold, it can help the upper stamping die 7 to quickly return to its original position, shorten the downtime of the equipment, and improve production efficiency.
