Description

Technical Field

[0001] The invention relates to a rubber injection machine, in particular to a station mechanism of a multifunctional rubber injection sole machine. Background Art

[0002] Rubber injection molding machine is a common equipment used to make rubber products. The rubber injection machine squeezes the rubber raw materials into shape, and then injects the raw materials into the mold with a large injection force, and vulcanizes and molds them in the mold.

[0003] Rubber soles are mainly processed and produced by rubber injection machines. Traditional rubber sole vulcanizing machines require manual cutting, weighing, die pulling, film prying, and color isolation plates, which are inefficient and labor-intensive.

[0004] Furthermore, traditional injection molding machines are typically used for molding single-color products. To produce multi-color rubber soles, manual labor is required to repeatedly remove and insert the upper and lower molds into the sole molding machine, as well as repeatedly manually remove the color separators and midframes. This is labor-intensive and inefficient. Finding a more efficient way to mold multi-color rubber products remains a challenge for those skilled in the art. Summary of the Invention

[0005] In order to solve the above problems, a multifunctional rubber injection sole machine standing mechanism is specially made, which completely solves the manual operations such as manual die pulling, prying, and end color isolation plates. It can improve the overall rigidity of the equipment, making it suitable for injection molding of two-color or multi-color sole products, improving production efficiency and saving labor.

[0006] To achieve the above-mentioned purpose, the present invention is solved through the following technical solutions: a standing mechanism of a multifunctional rubber injection sole machine, including a frame and an upper mold, a lower mold, a middle frame, a middle frame pulling-out mechanism, a color partition plate, a color partition plate pulling-out mechanism and a lower mold removal guide rail installed in the frame, the middle frame is arranged between the upper mold and the color partition plate, the lower mold is arranged below the color partition plate, the middle frame is slidably connected to the middle frame pulling-out mechanism, the color partition plate is slidably connected to the color partition plate pulling-out mechanism, and the lower mold is slidably connected to the lower mold removal guide rail.

[0007] Furthermore, the middle frame extraction mechanism includes two middle frame slide rails, a first worm gear reducer, a first transmission shaft and a first chain. The first transmission shaft and the middle frame are arranged between the two middle frame slide rails. The first chain is sleeved on the first transmission shaft. The first chain drives the middle frame to slide in the middle frame slide rails. The first worm gear reducer is arranged on one of the middle frame slide rails. The first worm gear reducer is connected to the first transmission shaft.

[0008] Furthermore, the color partition plate pulling-out mechanism includes two color partition plate slide rails, a second worm gear reducer, a second transmission shaft and a second chain. The second transmission shaft and the color partition plate are arranged between the two color partition plate slide rails. The second chain is mounted on the second transmission shaft. The second chain drives the color partition plate to slide in the color partition plate slide rails. The second worm gear reducer is arranged on one of the color partition plate slide rails, and the second worm gear reducer is connected to the second transmission shaft.

[0009] Furthermore, the guide rail includes an inner guide rail portion and an outer extension portion. The inner guide rail portion is fixedly installed inside the frame, and the outer extension portion extends outside the frame along the inner guide rail portion and is fixedly installed outside the frame.

[0010] Furthermore, the frame is also provided with guide columns, an upper oil cylinder and a lower push rod. The upper mold, lower mold, middle frame, middle frame pull-out mechanism, color partition plate and color partition plate pull-out mechanism are all mounted on the guide columns. The upper oil cylinder is installed on the frame and connected to the middle frame pull-out mechanism. One end of the lower push rod is fixedly installed on the frame, and the other end extends toward the bottom surface of the color partition plate. When the mold is separated, the lower push rod serves to limit the color partition plate pull-out mechanism.

[0011] The present invention is beneficial in that:

[0012] 1. The station mechanism of this multifunctional rubber injection sole machine has better rigidity than the traditional flip-type sole machine, and can be used for injection molding multi-color soles and two-color sole products.

[0013] 2. During mold separation, depending on the contour shape of the molded product, the molded product may remain in the middle frame cavity or in the lower mold cavity. The present invention provides a color isolation plate extraction mechanism, a middle frame extraction mechanism, and a lower mold removal guide rail, so that the above three can slide from the inside of the frame to the outside of the frame as needed, which is convenient for manual removal of the product and also reserves a larger operating space inside the frame.

[0019] The technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0020] A multifunctional rubber injection sole machine station mechanism includes a frame and an upper mold, a lower mold, a middle frame, a middle frame extraction mechanism, a color separator, a color separator extraction mechanism, and a lower mold removal guide rail installed within the frame. The middle frame is disposed between the upper mold and the color separator, the lower mold is disposed below the color separator, the middle frame is slidably connected to the middle frame extraction mechanism, the color separator is slidably connected to the color separator extraction mechanism, and the lower mold is slidably connected to the lower mold removal guide rail. The middle frame extraction mechanism includes two middle frame slide rails, a first worm gear reducer, a first transmission shaft, and a first chain. The first transmission shaft and the middle frame are disposed between the two middle frame slide rails, the first chain is sleeved on the first transmission shaft, and the first chain drives the middle frame to slide within the middle frame slide rails. The first worm gear reducer is disposed on one of the middle frame slide rails and is connected to the first transmission shaft. The color barrier plate removal mechanism includes two color barrier plate slides, a second worm gear reducer, a second drive shaft, and a second chain. The second drive shaft and the color barrier plate are disposed between the two color barrier plate slides. The second chain is mounted on the second drive shaft, driving the color barrier plate to slide within the color barrier plate slides. The second worm gear reducer is disposed on one of the color barrier plate slides, and the second worm gear reducer is connected to the second drive shaft. The removal guide rail includes an inner guide rail portion and an outer extension portion. The inner guide rail portion is fixedly mounted inside the frame, and the outer extension portion extends along the inner guide rail portion toward the outside of the frame and is fixedly mounted outside the frame. The frame is also equipped with guide columns, an upper oil cylinder and a lower ejector rod. The upper mold, lower mold, middle frame, middle frame extraction mechanism, color partition plate and color partition plate extraction mechanism are all mounted on the guide columns. The upper oil cylinder is installed on the frame and connected to the middle frame extraction mechanism. One end of the lower ejector rod is fixedly mounted on the frame, and the other end extends toward the bottom surface of the color partition plate. When the mold is separated, the lower ejector rod serves to limit the color partition plate extraction mechanism.

[0021] During actual operation, this positioning mechanism can be applied to the injection molding of single-color and multi-color soles, and the injection molding of double-color and multi-color soles. Since the middle frame and the color partition plate can slide in and out of the frame, when used as a single-color and multi-color sole, the color partition plate can be slid out of the frame along the color partition plate extraction mechanism. After the injection molding is completed, the guide rail or the middle frame is removed by the lower mold to slide the product to the outside of the frame, making it easier for the operator to take the product.

[0022] When making two-color or multi-color soles, the color partition plate is placed in the frame through the color partition plate extraction mechanism. After the upper and lower two-color uppers are injection-molded, the color partition plate is slid out along the color partition plate extraction mechanism, and the upper and lower molds are closed again. After the injection molding is completed, the guide rail or middle frame is removed by the lower mold to slide the product to the outside of the frame, making it easier for the operator to take the product.

[0023] It is obvious to those skilled in the art that the present invention is not limited to the details of the above-mentioned exemplary embodiments, and that the present invention can be implemented in other specific forms without departing from the spirit or essential characteristics of the present invention. Therefore, from any point of view, the embodiments should be regarded as exemplary and non-restrictive. The scope of the present invention is limited by the appended claims rather than the above description, and it is intended that all changes that fall within the meaning and scope of the equivalent elements of the claims are included in the present invention.
