Description

Technical Field

[0001] This utility model relates to the field of mold processing equipment technology, specifically to a fixed mold slider anti-retraction mechanism. Background Technology

[0002] A mold is a set of molds and tools used in industrial production to obtain desired products through methods such as injection molding, blow molding, extrusion, die casting, forging, smelting, and stamping. In short, a mold is a tool used to create shaped objects; this tool is composed of various parts, and different molds are composed of different parts. It primarily achieves the shaping of objects by changing the physical state of the material being molded.

[0003] In the field of notebook casing manufacturing, plastic parts are formed using injection molds, while magnesium alloy parts are formed using injection molding dies. During product molding, the positioning of the female mold core (fixed mold core) is primarily to ensure precise alignment between the moving and fixed molds during mold closing, preventing product defects or mold damage due to positional deviations. Existing technologies also employ hydraulic systems for positioning the female mold core. However, because the hydraulic oil in these systems is a compressible fluid, pressure fluctuations after the hydraulic cylinder pushes the mold core into position can cause minute displacements of 0.05~0.2mm. Eliminating these hydraulic fluctuations generated by hydraulic systems is a subject that has been continuously researched by those skilled in the art. Summary of the Invention

[0004] In view of the above situation and to overcome the current technical defects, this utility model provides a fixed mold slider anti-retrograde mechanism, which can effectively eliminate hydraulic fluctuations generated by the hydraulic system.

[0005] The technical solution adopted by this utility model is as follows:

[0006] The fixed mold slider anti-retraction mechanism includes a fixed plate and a hydraulic cylinder mounted on the fixed plate. A slider connecting block is mounted on the hydraulic cylinder. A bolt passes through the slider connecting block and is connected to the slider seat. A first spring is mounted on the bolt and limits its position on the slider seat. A slider core is mounted on the slider seat and is installed in the female mold core. Slider anti-retraction blocks are provided on both sides of the slider connecting block. The slider anti-retraction blocks are connected to the fixed plate through a second spring. A trapezoidal protrusion is provided on the slider connecting block, and a trapezoidal groove is provided on the slider anti-retraction block. The trapezoidal protrusion and the trapezoidal groove are matched and installed.

[0007] Preferably, the bottom surface of the slider seat is in movable contact with the top surface of the slider connecting block, and the bottom surface of the slider seat is slightly larger than the top surface of the slider connecting block.

[0009] The beneficial effects of this utility model by adopting the above structure are as follows:

[0010] This utility model adopts a fixed mold slider anti-retraction mechanism with dual hydraulic and mechanical positioning to ensure that the mold core of the mother mold maintains an accurate position during the mold operation. Through the synergistic effect of the hydraulic system and mechanical structure, the positioning accuracy and stability are improved. Attached Figure Description

[0023] As attached Figure 1-7 As shown, the technical solution adopted by this utility model is as follows:

[0024] The fixed mold slider anti-retraction mechanism includes a fixed plate 1 and a hydraulic cylinder 2 mounted on the fixed plate 1. A slider connecting block 3 is mounted on the hydraulic cylinder 2. A bolt 4 passes through the slider connecting block 3 and is connected to the slider seat 5. A first spring 6 is mounted on the bolt 4 and is limited to the slider seat 5. A slider core 7 is mounted on the slider seat 5 and is mounted on the female mold core 8. Slider anti-retraction blocks 9 are provided on both sides of the slider connecting block 3. The slider anti-retraction blocks 9 are connected to the fixed plate 1 through a second spring 10. A trapezoidal protrusion 11 is provided on the slider connecting block 3, and a trapezoidal groove 12 is provided on the slider anti-retraction block 9. The trapezoidal protrusion 11 and the trapezoidal groove 12 are matched and installed.

[0025] Preferably, the bottom surface of the slider seat 5 is in movable contact with the top surface of the slider connecting block 3, and the bottom surface of the slider seat 5 is slightly larger than the top surface of the slider connecting block 3.

[0026] Preferably, the slider anti-reverse block 9 and the top surface of the slider seat 5 are on the same horizontal plane, and the slider anti-reverse block 9 and the slider connecting block 3 have a movable contact surface.

[0027] The working principle is as follows:

[0028] This utility model is mainly installed on the female mold to ensure that the female mold core maintains an accurate position during mold operation. During mold closing: the hydraulic cylinder 2 starts, driving the connected slider connecting block 3 to move. The top surface of the slider connecting block 3 pushes the bottom surface of the slider seat 5 towards the female mold core 8. Since the trapezoidal protrusion 11 and the trapezoidal groove 12 are matched and installed, in this utility model mechanism, the so-called matching installation means that the trapezoidal protrusion 11 is similar to a latch, and the trapezoidal groove 12 is similar to a lock hole. The matching installation of the trapezoidal protrusion 11 and the trapezoidal groove 12 is similar to the installation of a latch and a lock hole. Under the thrust of the hydraulic cylinder 2, while the slider connecting block 3 pushes the slider seat 5 and the slider core 7 to position the female mold core 8, the trapezoidal protrusions 11 on both sides of the slider connecting block 3 also fall into the trapezoidal groove 12 for mechanical positioning. During mold closing and filling processes, the reverse force of the female mold core 8 will reach the slider core 7, slider seat 5, slider connecting block 3, and hydraulic cylinder 2. In the prior art, as described in the background art, a simple hydraulic cylinder 2 cannot achieve precise positioning. However, in the mechanism of this utility model, when the reverse force of the female mold core 8 reaches the position of the slider core 7, slider seat 5, and slider connecting block 3, the bottom surface of the slider seat 5 is slightly larger than the top surface of the slider connecting block 3, and the slider stop block 9 and the top surface of the slider seat 5 are on the same horizontal plane, and the slider stop block 9 and the slider connecting block 3 have a movable contact surface. In other words, the bottom surface of the slider seat 5 not only presses against the top surface of the slider connecting block 3 but also against the top surface of the slider stop block 9. As a result, the reverse force of the female mold core 8 is transmitted to both the slider connecting block 3 and the slider stop block 9. Since the slider stop block 9 is a mechanical structure that is precisely positioned on the fixed plate 1, there is no hydraulic fluctuation. In addition, the slider stop block 9 and the side of the slider connecting block 3 are connected by a locking structure similar to a lock tongue and a lock hole. This effectively eliminates the hydraulic fluctuation of the compressible fluid in the oil cylinder 2, thus ensuring the accurate position of the female mold core when producing products and improving product quality. Similarly, before the mold is opened, the hydraulic cylinder 2 drives the connected slider block 3 to start moving. Since the slider block 3 and the slider seat 5 are connected by a bolt 4 with a first spring 6, there is a certain movement gap between the slider block 3 and the slider seat 5 due to the presence of the first spring 6. When the slider block 3 initially moves, the slider seat 5 is stationary. The movement of the slider block 3 will slide the connected trapezoidal protrusion 11 out of the trapezoidal groove 12. While sliding out of the trapezoidal groove 12, it will squeeze the slider stop block 9 to move to both sides. When the position is sufficient, the top surface of the slider stop block 9 will detach from the slider seat 5. At this time, the slider seat 5 will fall down with the slider block 3 and fall onto the top surface of the slider block 3. After the slider seat 5 falls down, it will drive the connected slider core 7 to return to its position.
