Description

Technical Field

[0001] The utility model relates to the technical field of sole molding equipment, in particular to non-foaming polyurethane sole molding equipment. Background Art

[0002] At present, the production of soles generally uses sole molding equipment. The sole molding equipment uses an upper mold, a lower mold and a heating mechanism. The sole raw materials are added to the upper and lower molds. The sole raw materials themselves are in liquid form. They are mixed and poured into the mold and then vulcanized and formed under high temperature and pressure. However, when non-foaming polyurethane material is used as the sole raw material, bubbles are easily generated in the sole, affecting the quality of the sole after molding. It is also inconvenient to load and unload the materials during use. Utility Model Content

[0003] The technical problem to be solved by the present invention is to overcome the existing defects and provide non-foaming polyurethane sole molding equipment. A vacuuming mechanism is used to vacuum the inside of the mold to promote the overflow of bubbles in the non-foaming polyurethane material, reduce the bubbles in the sole after molding, and improve the quality of the sole after molding. The loading and unloading is convenient and fast, which can effectively solve the problems in the background technology.

[0004] To achieve the above-mentioned object, the present invention provides the following technical solution: a non-foaming polyurethane sole molding device, comprising a sole molding cabinet, wherein a working chamber is opened in the middle of the front side of the sole molding cabinet, and further comprising:

[0005] The loading and unloading control mechanism is installed on the bottom front side of the sole forming cabinet;

[0006] The lower mold mechanism includes a lower mold body, a non-foamed polyurethane sole molding groove, and a temperature control cavity. The lower mold body is installed on the loading and unloading control mechanism, and two non-foamed polyurethane sole molding grooves are provided on the upper side of the lower mold body. The temperature control cavity is provided on the bottom of the lower mold body.

[0007] A temperature control mechanism is installed in the temperature control cavity;

[0008] The upper mold mechanism is installed in the working cavity and is located on the upper side of the lower mold body. The upper mold mechanism is connected to the vacuum pumping mechanism.

[0009] The loading and unloading control mechanism can drive the lower mold body to move up and down, and can make the lower mold body approach or move away from the upper mold mechanism. At the same time, it can also drive the lower mold body to move forward and backward, which is convenient for loading and unloading in the lower mold body. When in use, the loading and unloading control mechanism drives the lower mold body to move downward, allowing the lower mold body to leave the upper mold mechanism, and then the loading and unloading control mechanism drives the lower mold body to move forward, so that the two non-foamed polyurethane sole molding grooves on the lower mold body leak out, and non-foamed polyurethane material is placed in the two non-foamed polyurethane sole molding grooves. Then the loading and unloading control mechanism drives the lower mold body to move backward until the lower mold body is located directly below the upper mold mechanism, and then the loading and unloading control mechanism drives the lower mold body to move forward. The mold body moves upward to bring the lower mold body close to the upper mold mechanism. The temperature control mechanism is used to heat the non-foaming polyurethane material in the non-foaming polyurethane sole molding groove to reduce its viscosity and improve its fluidity, so that the non-foaming polyurethane material can cover the bottom of the non-foaming polyurethane sole molding groove more quickly, while providing sufficient vulcanization temperature. The vacuuming mechanism vacuums the molding cavity between the lower mold body and the upper mold mechanism to promote the overflow of bubbles in the non-foaming polyurethane material. After the non-foaming polyurethane is vulcanized and molded, the loading and unloading control mechanism moves the lower mold body downward and then forward to take out the sole formed in the non-foaming polyurethane sole molding groove, thereby completing the molding process of the non-foaming polyurethane sole.

[0010] Furthermore, the loading and unloading control mechanism includes a lifting assembly and a forward and backward movement assembly. The lifting assembly is mounted on the bottom front side of the sole molding cabinet, and the forward and backward movement assembly is connected to the top of the lifting assembly. The lifting assembly is used to move the lower mold body up and down, and the forward and backward movement assembly is used to move the lower mold body back and forth, facilitating loading and unloading of materials within the non-foamed polyurethane sole molding groove on the lower mold body.

[0011] Furthermore, the lifting assembly includes a support plate, a guide column, a stabilizing bend, a hydraulic cylinder, a lifting support plate, and a column. The front side of the sole forming cabinet is fixedly connected to a horizontal support plate at a position corresponding to the bottom of the working chamber. The four corners of the top of the support plate are fixedly connected to the bottom ends of the four guide columns. The top of the guide column is connected to the front side of the sole forming cabinet through the stabilizing bend, and the four guide columns are slidably connected to the four sliding holes on the lifting support plate. Four columns distributed in a rectangular array are fixedly connected to the lifting support plate. The bottom center of the support plate is fixedly connected to a hydraulic cylinder. The telescopic end of the top of the hydraulic cylinder passes through the circular hole on the support plate and is connected to the bottom of the lifting support plate. The telescopic end of the hydraulic cylinder can drive the lifting support plate to move up and down along the guide column. The lifting support plate can drive the forward and backward moving assembly and the lower mold body to move up and down through the column. The stabilizing bend is fixedly installed on the top of the guide column to maintain the stability of the guide column, so that the lifting support plate can move up and down more smoothly.

[0012] Furthermore, the forward and backward movement assembly includes a longitudinal slide rail, a linear motor guide rail, a linear motor, and a lower mold support. The two columns on the left are fixedly connected to a longitudinal slide rail, and the two columns on the right are fixedly connected to another longitudinal slide rail. The two longitudinal slide rails are respectively fixedly connected to two linear motor guide rails, and the two linear motor guide rails are respectively equipped with two linear motors. The left and right sides of the lower mold support are respectively slidably connected to the two longitudinal slide rails, and the two linear motors are respectively fixedly connected to the top two sides of the lower mold support. The lower mold body is installed in the middle of the lower mold support. The longitudinal slide rail limits the lower mold support so that the lower mold support can only move forward and backward. The linear motor moves forward and backward along the linear motor guide rail, which can drive the lower mold support to move forward and backward along the longitudinal slide rail, thereby driving the lower mold body to move forward and backward.

[0013] Furthermore, the temperature control mechanism includes a heater, and a heater is provided in the temperature control cavity. The heater can heat the lower mold body, reduce the viscosity of the non-foamed polyurethane in the non-foamed polyurethane sole molding groove, and improve its fluidity. The heater can use a spiral heating wire.

[0014] Furthermore, the upper mold mechanism includes an upper mold body and an upper mold mounting assembly. The upper mold body is mounted in the working chamber via the upper mold mounting assembly, and the upper mold body is located above and to the side of the lower mold body. The upper mold mounting assembly is used to detachably mount the upper mold body, and the upper mold body and the lower mold body form a complete sole mold.

[0015] Furthermore, the vacuuming mechanism includes an exhaust port, an exhaust pipeline, a solenoid valve, and a vacuum pump. The exhaust port is provided on the upper mold body at a location corresponding to the groove for forming the non-foamed polyurethane sole. The top of the exhaust port is connected to the air inlet of a vacuum pump via an exhaust pipeline. The vacuum pump is mounted at the top of the working chamber, and the exhaust pipeline is equipped with a solenoid valve. The vacuum pump evacuates the sole mold through the exhaust pipeline and the exhaust port, promoting the escape of bubbles in the non-foamed polyurethane material within the groove for forming the non-foamed polyurethane sole, thereby improving the quality of the sole molding. The solenoid valve is used to control the on / off state of the exhaust pipeline.

[0016] Compared with the existing technology, the beneficial effects of this non-foaming polyurethane sole molding equipment are:

[0017] 1. The loading and unloading control mechanism can drive the lower mold body to move up and down, allowing the lower mold body to move close to or away from the upper mold mechanism. At the same time, it can also drive the lower mold body to move forward and backward, making it convenient to load and unload materials in the lower mold body. Loading and unloading is convenient and fast.

[0018] 2. The vacuum pump draws vacuum into the sole mold through the exhaust pipe and the exhaust port, promoting the overflow of bubbles in the non-foaming polyurethane material, reducing bubbles in the sole after molding, and improving the quality of the sole after molding.
