Description

Technical field:

[0001] The invention relates to the field of moulds, in particular to a multi-directional movable slider side-drawing mould. Background technology:

[0002] Most molds nowadays are composed of sliders and lifters. Generally, after designing a certain demolding slope, the product can be smoothly injected without product damage or the phenomenon that the product can be molded but cannot be demolded. When there are some larger features in the product, or when the lifter interferes with the slider, the lifter can be used for ejection. However, due to the larger features or collision with the slider, the plastic part will wrap around the lifter when ejecting due to the softness of the plastic part. If it is forcibly pulled out, it will affect the surface quality of the plastic part or the plastic part will break, which will affect the design of the molded part.

[0003] Regarding the basic features on the surface of the plastic part, due to the product structure requirements, the slider cannot meet the required features, the inclined top will interfere with the slider, and the inclined top cannot be ejected to achieve the basic features of the product. How to obtain this basic feature is a big problem for technical personnel in this field. Summary of the invention:

[0004] In order to solve the above technical problems, the multi-directional movable slider side-drawing mold of the present invention comprises: a side-drawing mechanism of a movable mold plate, a square iron and a lower mold fixed plate are arranged in sequence from top to bottom, and a push plate and a push plate fixed plate are arranged in sequence at the lower end of the square iron.

[0005] A mold opening groove is provided in the middle of the movable template, symmetrical slide rails are provided on both sides of the mold opening groove, matching wedge blocks are provided on the slide rails, a core is provided in the middle of the mold opening groove, a pulling rod is provided in the middle of the surface of the core, tiger's mouths are provided at both ends of the core, a slider is provided on the side of the core, an inclined guide column groove is provided on the surface of the slider, a matching inclined guide column is provided in the inclined guide column groove, a shovel is sleeved on the circumferential surface of the inclined guide column, a guide block is provided on the bottom surface of the shovel, a T-shaped main slider is provided in the middle of the connecting surface between the slider and the core, slide grooves are provided at both ends of the core, a secondary slider is provided in the slide groove, and a guide groove is provided on the top surface of the core. Through the cooperation of the guide groove and the guide block, a first return spring is provided at the lower end of the front side of the main slider, and a second return spring is provided on the side of the secondary slider. The second return spring is fixed in position by a pressure block, and the pressure block is fixed to the secondary slider by screws.

[0006] According to a further technical solution, the square iron and the lower mold fixing plate are fixedly connected by screws.

[0007] According to a further technical solution, limit screws are provided at both ends of the mold opening groove.

[0008] Compared with the prior art, the invention has the following beneficial effects: it will not affect the surface quality of the plastic part or the plastic part will not break, and it can also be simple in structure, can also ensure the appearance, and has a low cost. Compared with the traditional mold, it realizes the function of zero-degree demoulding without dragging the product, ensures the appearance of the molded product, and the structure of the slider core-pulling mechanism is simple and stable, with strong applicability, simple structure, reasonable and reliable design, and simple processing, so that a complete plastic part can be obtained with good surface quality, which improves production efficiency and product requirements.

Specific implementation method:

[0014] As shown in the figure, the multi-directional movable slider side-drawing mold includes: a side-drawing mechanism of a movable mold plate 1, a square iron 5 and a lower mold fixing plate 6 are arranged in sequence from top to bottom, and a push plate 3 and a push plate fixing plate 4 are arranged in sequence at the lower end of the square iron 5, and the square iron 5 and the lower mold fixing plate 6 are fixedly connected by screws.

[0015] A mold opening groove is provided in the middle of the movable template 1, a limit screw 16 is provided at the end of the mold opening groove, symmetrical slide rails are provided on both sides of the mold opening groove, and matching wedge blocks 11 are provided on the slide rails. A core 2 is provided in the middle of the mold opening groove, a pulling rod 15 is provided in the middle of the surface of the core 2, and tiger's mouths 7 are provided at both ends of the core 2. A slider is provided on the side of the core 2, and an inclined guide column groove is provided on the surface of the slider. A matching inclined guide column 12 is provided in the inclined guide column groove, and a shovel machine 21 is sleeved on the circumferential surface of the inclined guide column 12. The inclined guide column 12 cooperates with the shovel machine 21 to control the moving direction of the slider, and the position of the shovel machine 21 is fixed by the inclined guide column 12. A guide block is provided on the bottom surface of the shovel machine 21, and a T-shaped main slider 9 is provided in the middle of the connecting surface between the slider and the core 2. There is a slide groove, in which a secondary slider 8 is arranged, and a guide groove is arranged on the top surface of the core 2. Through the cooperation of the guide groove and the guide block, the shovel 21 can control both the longitudinal movement of the main slider 9 and the lateral movement of the secondary slider 19. The lower end of the front side of the main slider 9 is provided with a first return spring 20, and the first return spring 20 resets the main slider 9. The side of the secondary slider 8 is provided with a second return spring 17, and the second return spring 17 is fixed by a pressure block 10. The pressure block 10 is fixed to the secondary slider 8 by screws. The second return spring 17 controls the secondary slider to return to its original position. The movable template 1 is fixed to the wedge block 11 by screws to control the movement accuracy of the main slider 9. Finally, the stroke of the slider 9 is limited by the screw 16. In the process of mold closing, the main slider 9 cooperates with the core 2, and the secondary slider 19 moves to both sides under the action of the shovel 21 to form product features. At the same time, after the main slider 9 moves, the gap of the secondary slider 8 is automatically compensated to form a complete product.

[0016] As can be seen from the above, this will not affect the surface quality of the plastic parts or the plastic parts will not break, and the structure is simple, the appearance is guaranteed, and the cost is low. Compared with the traditional mold, it realizes the function of zero-degree demoulding without dragging the product, ensuring the appearance of the molded product, and the structure of the slider core-pulling mechanism is simple and stable, and has strong applicability.
