Description

Technical Field

[0001] The utility model relates to the technical field of sole production, in particular to an injection shoe mould used for sole processing. Background Art

[0002] The structure of the sole is quite complex. In a broad sense, it can include all materials that make up the bottom, such as the outsole, midsole and heel. The common properties of general sole materials should be wear resistance, water resistance, oil resistance, heat resistance, pressure resistance, impact resistance, good elasticity, easy to adapt to the foot shape, not easy to deform after shaping, heat preservation, easy to absorb moisture, etc. There are many types of sole materials. The preparation materials of the sole generally include rubber, plastic, rubber-plastic composite materials, etc. The molding methods include compression molding, injection molding, etc. In the process of sole processing and production, auxiliary molds are required for processing.

[0003] In the prior art, the mold for sole injection molding is generally installed on an injection molding machine, and usually includes corresponding male and female molds. After the two molds are closed, the raw materials are injected to form the mold. After the molds are opened, the molded product is taken out, and one injection molding is completed. Since different shoe types require different sole shapes, the staff needs to replace different molds to assist production during the injection molding process. However, the mold is generally installed on the equipment by a large number of fixing bolts, which causes the staff to remove a large number of bolts when replacing the mold, resulting in a large workload for the staff and low replacement efficiency.

Limit pins 55 are symmetrically fixed, and limiting holes 59 that are compatible with the limit pins 55 are opened on both sides of the upper mold seat 7 and the lower mold seat 4. 5 are provided with driving mechanisms, which are respectively used to drive the double-headed screws 53 of the same group to rotate. The staff uses the positioning pins and positioning holes to place the upper mold base 7 and the lower mold base 4 for sole processing on the movable base 1 and the fixed base 3 respectively, and then controls the driving mechanism to realize the rotation of the double-headed screw 53. Since the threads at both ends of the double-headed screw 53 rotate in opposite directions, the movable plate 54 can be moved toward each other along the movable groove 51. When the two sides of the movable plate 54 mold base are in contact with each other, the limit pin 55 will be stuck in the limit hole 59 of the mold base, thereby completing the rapid installation of the upper mold base 7 and the lower mold base 4. When it is necessary to replace the sole mold base of different shapes, the staff only needs to use the driving mechanism to cooperate with the double-headed screw 53, the movable plate 54, the limit pin 55 and the limit hole 59 to realize the rapid replacement of the mold base, thereby improving the efficiency of the staff in replacing the mold base.

[0024] A hydraulic cylinder 6 is fixedly installed in the middle of both sides of the top of the fixed seat 3, and the driving ends of the hydraulic cylinder 6 are fixedly installed in the middle of both sides of the bottom of the movable seat 1. A movable groove 51 is opened in the middle of the side where the movable seat 1 and the fixed seat 3 are close to each other, and the movable plates 54 are slidably installed in the movable grooves 51 on the same side. By controlling the hydraulic cylinder 6, the piston rod inside the hydraulic cylinder 6 can drive the movable seat 1 to move axially along the guide rod 2, so as to achieve the mold closing between the upper mold base 7 and the lower mold base 4. The driving mechanism includes a stepper motor 56, which is fixedly installed on the fixed seat 3 and the movable seat In the middle of one side, a driving gear 57 is fixedly installed at the driving end of the stepping motor 56, and a driven gear 58 is meshed and connected to the front side of the driving gear 57. The driven gears 58 are respectively fixedly installed on the end of one side of the double-headed screw 53 of the same group. By controlling the stepping motor 56, the stepping motor 56 can drive the driving gear 57 to rotate. Since the driving gear 57 and the driven gear 58 are meshed with each other, the driven gear 58 can drive the double-headed screw 53 to rotate synchronously, thereby realizing the rapid disassembly and assembly of the movable plate 54 with the limit pin 55 and the limit hole 59 to the mold base.

[0025] The demoulding assembly 8 is arranged inside the lower mold base 4. The demoulding assembly 8 includes a notch 83, which is opened in the middle of the lower mold base 4.

Abutment plates 81 are fixedly installed in the middle of the front and rear sides of the upper mold base 7. A guide groove 84 is opened in the middle of the front and rear sides of the lower mold base 4 and the front and rear sides of the top plate 82 are slidably installed in the guide groove 84. When the upper mold base 7 moves downward, the abutment plates 81 are fixedly installed. 1 will abut against both ends of the top plate 82. As the movable base 1 continues to move, the top plate 82 will move downward along the guide groove 84. At this time, the spring 85 will be compressed. When the upper mold base 7 and the lower mold base 4 complete the mold closing, the top plate 82 will block the notch 83, so that an annotation chamber is formed between the upper mold base 7 and the lower mold base 4. After the sole injection molding is completed, the upper mold base 7 and the lower mold base 4 will separate. When the top plate 82 loses the restriction of the abutment plate 81, the spring 85 will push the top plate 82 upward, thereby completing the rapid demoulding of the sole in the mold base without manual demoulding, thereby improving the demoulding efficiency.

[0026] When the shoe bottom is in the state of being molded, the spring 85 in the demoulding assembly 8 will push the top plate 82 upwards to demould the shoe bottom, thereby improving the demoulding efficiency of the shoe bottom.
