Description

Technical Field

[0001] The utility model relates to the technical field of molds, in particular to an anti-sticking residue extrusion profile injection mold. Background Art

[0002] A mold is a tool or device used to manufacture objects of a specific shape or form. An extruded profile refers to a material with a specific cross-sectional shape made through an extrusion process, such as aluminum profiles and plastic profiles. Extruded profiles require polished injection molds for operation. Injection molds are used to inject molten plastic into the mold cavity, and after cooling and solidification, plastic parts of the desired shape are obtained.

[0003] At present, injection molds still have certain shortcomings, such as the inconvenience of removing the mold after molding:

[0004] In order to overcome the problem of inconvenient removal of the mold after molding, the existing technology (publication number: CN211588007U) Chinese patent discloses an extrusion mold for aluminum alloy hollow profiles. The device is reasonably designed. The arrangement of the pressure dividing column and the built-in groove facilitates the dispersion of pressure without concentrating it on one point, effectively improving the service life. The threaded rod is arranged to facilitate the upward and downward sliding of the fixed block. At the same time, the push-out block is arranged to facilitate the removal of the mold processed inside the second injection module from the lower end under the drive of the fixed block, thereby facilitating removal and improving work efficiency.

[0005] However, the injection molds currently used still have certain shortcomings. In the above-mentioned document, the fixed block is driven by a threaded rod to slide up and down to realize the ejection and demoulding of the material. However, direct ejection of the material is prone to adhesion and adsorption, and there may be material residue, which is difficult to clean and affects the subsequent processing efficiency. Therefore, the existing structure needs to be improved. Utility Model Content

DETAILED DESCRIPTION

[0027] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0028] Example 1: Figure 1-Figure 4The technical solution shown in the figure, the utility model provides the following technical solution: In order to solve the problem of material adhesion and residue when the injection mold is demoulded, a pushing mechanism is disclosed: comprising a mold body 1, a pressing mold 2 is arranged inside the mold body 1, a movable rod 3 is fixed inside the pressing mold 2, a movable groove 101 is opened through the side of the mold body 1, and six movable grooves 101 are opened, an extrusion block 102 is arranged inside the movable groove 101, a fixed rod 103 is fixed at the bottom of the extrusion block 102, and the fixed rod 103 is inserted through the sliding block 102. Inside 118, the external block 118 is fixed to the surface of the mold body 1, and a pushing mechanism is provided on the outside of the mold body 1 to prevent the adhesion of mold demoulding residues; the bottom of the mold body 1 is connected to the chassis 107, and the surface of the chassis 107 is provided with an ejection mechanism for convenient mold demoulding. The pushing mechanism includes a fixed ring 104, which is fixed to the surface of the mold body 1. The surface of the fixed ring 104 is rotatably connected to the rotating ring 105. Six extrusion grooves 106 are opened on the top of the rotating ring 105, and the fixed rod 103 penetrates and slides inside the extrusion groove 106;

[0029] When the mold is in use, injection molding is required inside the mold body 1, and then the movable rod 3 is pushed to drive the die 2 to move to the inside of the mold body 1 for extrusion to realize material molding. After the material is molded, the rotating ring 105 can be rotated through the fixed ring 104. When the rotating ring 105 rotates, it can drive the extrusion groove 106 to rotate. When the extrusion groove 106 rotates, it can extrude the surface of the fixed rod 103. When the fixed rod 103 is extruded, it can slide through the external block 118. At the same time, the fixed rod 103 can drive the extrusion block 102 to move. When the extrusion block 102 moves, it can slide through the movable groove 101. The extrusion block 102 slides and can extrude the side wall of the material at the same time. Since there are six extrusion blocks 102, six can extrude the material at the same time. After being extruded, the material will lose its adhesion to the inner wall of the mold body 1. After the adhesion is reduced, residue and adhesion can be prevented during demoulding, thereby improving the demoulding effect of the injection mold.

[0030] Example 2: Figure 1-Figure 5The technical solution shown in the figure, the utility model provides the following technical solution: In order to solve the problem that the injection mold is inconvenient to demould and the material is prone to residual adhesion, based on the first embodiment, an ejection mechanism is disclosed: the ejection mechanism includes a T-ring 108, the T-ring 108 is fixed to the top of the chassis 107, the T-ring 108 rotates inside the T-slot 109, the T-slot 109 is opened at the bottom of the mold body 1, a gear ring 110 is installed on the side of the chassis 107, and a gear block 111 is meshed and connected to the side of the gear ring 110. The upper surface of the gear block 111 is fixed. There is a threaded block 112, which is threadedly connected to the inside of the fixed rod 103. A sleeve 113 is sleeved on the surface of the threaded block 112. A guide block 119 is symmetrically fixed to the surface of the sleeve 113. The guide block 119 passes through and slides inside the guide groove 115. The guide groove 115 is symmetrically opened on the inner side of the external block 118. A limit block 116 is symmetrically fixed inside the sleeve 113. The limit block 116 slides inside the limit groove 117. The limit groove 117 is symmetrically opened on the surface of the fixed rod 103. The fixed rod 103 passes through and slides inside the sleeve 113.

[0031] When the rotating ring 105 of the injection mold rotates, it can drive the fixed rod 103 to slide through the external block 118. When the fixed rod 103 slides, it can drive the sleeve 113 and the gear block 111 to move. When the sleeve 113 moves, it can drive the guide block 119 to move. When the guide block 119 moves, it can slide through the guide groove 115. When the gear block 111 moves to the side of the gear ring 110, the extrusion block 102 can extrude the side of the material. After extrusion, the rotating chassis 107 can drive the T-ring 108 to rotate. When the T-ring 108 rotates, it can rotate through the T-slot 109. When the T-ring 108 rotates, it can drive the gear ring 110 to rotate. When the gear ring 110 rotates, it can mesh with the gear block 111 and rotate. The meshing rotation of the gear block 111 can drive the thread When the block 112 rotates, the threaded block 112 can drive the fixed rod 103 to slide threadedly when it rotates, and when the fixed rod 103 slides threadedly, it can drive the limiting groove 117 to rotate and move. When the limiting groove 117 rotates, it can be stably guided by the limiting block 116, and the limiting block 116 can be guided by the sleeve 113. At the same time, the limiting groove 117 can slide by the limiting block 116, and when the fixed rod 103 slides, it can push the extrusion block 102 to move upward. Since the extrusion block 102 is an inclined surface, it is extruding the material. When it moves upward, it can push the material up. After the material is pushed up, the demoulding effect can be achieved, which improves the efficiency of demoulding. At the same time, it can further prevent the material from adhering to or remaining on the inner wall of the mold body 1, thereby improving the convenience of using the mold.

[0032] Example 3: Figure 6The technical solution shown in the figure, the utility model provides the following technical solutions: In order to solve the problem that the gear block 111 of the injection mold wears quickly and is easy to get stuck, based on the second embodiment, a rolling mechanism is disclosed: a rolling mechanism for improving the meshing efficiency is provided inside the gear block 111, and the rolling mechanism includes a rolling groove 120, the rolling groove 120 is opened at the bottom of the gear block 111, and there are multiple rolling grooves 120, and a rolling ball 114 is connected to the rolling groove 120 in a rolling manner, and the rolling ball 114 protrudes from the rolling groove 120, and the rolling ball 114 rolls on the upper surface of the chassis 107, the injection mold When the gear block 111 moves, it can drive the ball 114 to move. When the ball 114 moves, it can move on the surface of the chassis 107. When the ball 114 and the chassis 107 move, friction will be generated. Through the friction, the ball 114 can roll inside the rolling groove 120. When the ball 114 rolls, the wear of the gear block 111 when it moves on the upper surface of the chassis 107 can be reduced. At the same time, the ball 114 can improve the smoothness of the gear block 111 when it moves, and the gear block 111 can also improve efficiency when it rotates in meshing with the gear ring 110, prevent jamming, and indirectly improve the mold demolding effect.

Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
