Description

Technical Field

[0001] The invention relates to the field of mold processing, and in particular to a structure for preventing a sliding block from retreating in a plastic mold. Background Art

[0002] When processing plastic molds, if a hydraulic cylinder is used to provide pressure all the time, energy consumption will increase over a long period of time. The locking valve method is cost-effective and is easily damaged after long-term use in a high-pressure environment. The improved top pressure slider method is easy to slip during processing, which causes the color of the finished product in the plastic mold to decline. In addition, the internal pressure of the mold is insufficient due to slippage, causing problems such as plastic deformation. Therefore, a structure is designed to prevent the slider from retreating in a plastic mold. Summary of the invention

[0003] The object of the present invention is to provide a structure for preventing a slider from retreating in a plastic mold to solve the above technical problems. To achieve the above object, the present invention adopts the following technical solutions: A structure for preventing a slider from retreating in a plastic mold comprises a plastic mold, a hydraulic cylinder, a cylinder arm, a guide platform, a shovel base block, a guide sleeve, a mold top pressure slider, and a T-block. The cylinder arm is connected to one side of the hydraulic cylinder and can move laterally on one side of the hydraulic cylinder. The shovel base block is connected to the guide platform and can slide laterally on the guide platform. The T-block is fixed to the top oblique side surface of the shovel base block. The mold top pressure slider is arranged on the top side of the shovel base block. The bottom end of the mold top pressure slider is connected to the T-block.

The top end of the mold top pressure slider contacts the plastic mold. The positions of the plastic mold, the hydraulic cylinder, the guide platform, and the guide sleeve are relatively fixed.

[0011] A structure for preventing a slider from retreating in a plastic mold comprises a plastic mold 1, a hydraulic cylinder 2, a cylinder arm 3, a guide platform 4, a shovel base block 5, a guide sleeve 6, a mold top pressure slider 7, and a T-block 8. The cylinder arm 3 is connected to one side of the hydraulic cylinder 2, and the cylinder arm 3 can move laterally on one side of the hydraulic cylinder 2. The shovel base block 5 is connected to the guide platform 4, and the shovel base block 5 can slide laterally on the guide platform 4. The T-block 8 is fixed on the top oblique side of the shovel base block 5. The mold top pressure slider 7 is arranged on the top side of the shovel base block 5. The bottom end of the mold top pressure slider 7 is connected to the T-block 8. The guide sleeve 6 is arranged on the outside of the mold top pressure slider 7. The side end of the cylinder arm 3 is fixed to the shovel base block 5. The top end of the mold top pressure slider 7 contacts the plastic mold 1. The positions of the plastic mold 1, the hydraulic cylinder 2, the guide platform 4, and the guide sleeve 6 are relatively fixed.

[0012] The bottom side of the shovel base block 5 is provided with an embedded slider 9, and the guide platform is provided with an embedded slide groove 10, the embedded slider 9 is embedded in the embedded slide groove 10, and the embedded slider 9 can slide laterally in the embedded slide groove 10, the top side of the shovel base block 5 is provided with a slider contact slope 11, the middle section of the slider contact slope 11 is provided with an anti-skid platform 12, the bottom end of the mold top pressure slider 7 is provided with a shovel base contact slope 13, the bottom end of the shovel base contact slope 13 is provided with an anti-skid platform 12, and the shovel base contact slope 13 is provided with an anti-skid platform 12. The slider contact inclined surface 11 is arranged in contact, the anti-skid platform 12 on the top side of the shovel base block 5 and the anti-skid platform 12 at the bottom end of the mold top pressure slider 7 can be arranged closely to each other, a T-shaped slot 14 is arranged on the shovel base contact inclined surface 13, the T-shaped block 8 is embedded in the T-shaped slot 14, and the T-shaped block 8 can be slidably adjusted in the T-shaped slot 14, a mold connecting push rod 15 is arranged on the top of the mold top pressure slider 7, the top end of the mold connecting push rod 15 is connected to the plastic mold 1, and the mold top pressure slider 7 can move up and down on the inner side of the guide sleeve 6.

[0013] Working principle of the present invention: In the structure, a shovel base block 5 is added to the bottom side of the mold top pressure slider 7, so that the movement direction of the oil cylinder arm 3 is perpendicular to the movement direction of the mold top pressure slider 7. During injection molding, the vertical surface on the shovel base block 5 and the movement direction of the mold top pressure slider 7 are used to lock the slider. The anti-skid platform 12 can be locked with each other to prevent the mold top pressure slider 7 from retreating during injection molding. When the mold top pressure slider 7 moves to the top, the shovel base block 5 can also provide a stable supporting force. When the mold top pressure slider 7 moves to the top, the oil cylinder pulls the shovel base block 5 to convert the direction of the driving force by 90° under the action of the T-block 8 and the guide platform 4, so that the mold top pressure slider 7 retreats downward and the mold connection push rod 15 is separated from the plastic mold 1.
