[0027] like Figure 1-7As shown, a bathroom mirror cabinet production mold includes an upper mold 1, a lower mold 2 assembled with the upper mold 1, and a slider core-pulling device 3 disposed within the upper mold 1. The upper mold 1, lower mold 2, and slider core-pulling device 3 together form a molding cavity 4. An injection port 5 and a runner 6 are provided on the upper mold 1, and the runner 6 communicates with the molding cavity 7. An installation groove 8 is provided within the upper mold 1, and the slider core-pulling device 3 is disposed within the installation groove 8. The slider core-pulling device 3 includes limiting seats 9 symmetrically arranged at intervals within the installation groove 8. Between the lower end face of the limiting seat 9 and the bottom surface of the installation groove 8... A limiting groove is formed, and a slider 10 is provided between the two limiting seats 9. A forming protrusion 11 is provided at the front end of the slider 10 to facilitate the formation of holes during the molding of the bathroom mirror cabinet. Limiting protrusions 12 are respectively provided on the lower part of the two side walls of the slider 10. The limiting protrusions 12 are movably disposed in the limiting groove. An inclined groove 13 is provided on the rear end of the slider 10. A drive rod 14 is provided in the upper mold 1. A drive head 15 is provided at the corresponding position of the drive rod 14 and the inclined groove 13 to drive the slider 10 to move back and forth. The drive head 15 is movably disposed in the inclined groove 13.

[0028] In this invention, the slider core-pulling device 3 is fully integrated into the mounting groove 8 inside the upper mold 1, eliminating the need for additional external space or complex auxiliary mechanisms, thus making the overall structure of the mold simpler and more compact. The symmetrically spaced limiting seats 9 and the slider 10 running between them provide double-sided support for the slider, effectively preventing it from tilting or twisting on one side during movement and ensuring uniform force distribution.

[0029] In this invention, the limiting flanges 12 on both sides of the lower part of the slider 10 are movably disposed in the limiting groove formed by the lower end face of the limiting seat 9 and the bottom surface of the mounting groove 8. Through this lower-positioned flange and groove structure, the slider is effectively provided with stable horizontal support and precise linear guidance, ensuring that it can only move smoothly along the preset straight direction, greatly reducing swaying and off-center load, and improving motion accuracy and service life.

[0030] The drive head 15 on the drive rod 14 of this invention is inserted into the inclined groove 13 at the rear end of the slider 10. During mold opening and closing, the vertical linear motion of the drive rod 14 is converted into the horizontal forward and backward motion of the slider 10 (core pulling and resetting) through the inclined surface of the inclined groove 13. This mechanical transmission method is direct, reliable, and has high power transmission efficiency.

[0031] When the molding process is complete and the mold is opened, the drive rod 14 drives the drive head 15 to move upward. Since the drive head 15 is embedded in the inclined groove 13, its upward movement forces the slider 10 to move smoothly and horizontally away from the molding cavity along the limiting groove. Simultaneously, the molding protrusion 11 embedded in the bathroom mirror cabinet hole smoothly retracts. This horizontal, linear retraction effectively reduces the relative sliding friction between the side of the molding protrusion 11 and the inner wall of the product hole, thus effectively avoiding defects such as roughening, scratching, or even tearing of the inner wall of the hole caused by tilted retraction or friction, which may occur with traditional core-pulling methods. This significantly improves the surface quality and dimensional accuracy of the product, especially the edges of the hole.

[0032] In this invention, the inclined groove 13 is a T-shaped inclined groove, and the drive head 15 is a T-shaped drive block. The T-shaped drive block and the T-shaped inclined groove work together to not only transmit forward and backward driving forces but also effectively prevent the slider from rotating during movement. Simultaneously, they provide a larger contact area, improving load-bearing capacity and wear resistance.

[0033] In this invention, a positioning groove 16 is provided on the rear side of the mounting groove 8, and a positioning connector 17 is provided on the drive rod 14 at a corresponding position to the positioning groove 16. The slider 10 includes a slider seat 25, a protrusion 26 is provided at the front end of the slider seat 25, a positioning step 27 is formed between the protrusion 26 and the end face of the slider seat 25, the forming protrusion 11 is provided on the end face of the protrusion 26, and the inclined groove 13 is provided on the rear end of the slider seat 25.

[0034] When the drive head 15 is inserted into the lowest end of the inclined groove 13, the positioning connector 17 is inserted into the positioning groove 16. At the same time, the positioning step 27 presses against the groove of the mounting groove 8 inside the upper mold 1. The slider 10 is positioned on the wall, thus achieving dual positioning and ensuring that it does not move during the injection molding process.

[0035] In this invention, a first inclined surface 28 is provided at the rear end of the slider 10, and the inclined groove 13 passes through the first inclined surface 28. A second inclined surface 29 is provided at the lower end of the drive rod 14 at a position corresponding to the first inclined surface 28, so that when the drive head 15 is inserted into the inclined groove 13, the second inclined surface 29 abuts against the first inclined surface 28.

[0036] The upper mold 1 of this utility model includes an upper mold core 18 and an upper template 19, and the drive rod 14 is fixedly mounted on the upper template 19 by connecting bolts 20.

[0037] In this utility model, a receiving long groove 21 is provided at the corresponding position of the limiting seat 9 and the limiting protrusion 12, and a guide protrusion 22 is provided at the corresponding position of the limiting protrusion 12 and the receiving long groove 21. The guide protrusion 22 is movably disposed in the receiving long groove 21, and a top pressure spring 23 is provided between the guide protrusion 22 and the receiving long groove 21 to drive the slider 10 to move towards the drive rod 14.

[0038] The top-compression spring 23 of this invention always applies a constant force, forcing the guide protrusion 22 to drive the slider 10 to continuously move towards the drive rod 14. During installation, the top-compression spring 23 drives the guide protrusion 22 to press against the end face of the accommodating long groove 21. At this time, the slider 10 is in the predetermined position, which facilitates the alignment of the drive head 15 with the inclined groove 13 and makes installation convenient.

[0039] The preload of the top spring 23 provides a flexible constraint, which helps to suppress minor jitter or irregular jumping of the slider 10 during motion reversal or acceleration / deceleration, making the entire core pulling / resetting process smoother and more stable.

[0040] With prolonged use, the contact surface between the slant groove and the drive head will experience slight, uniform wear. The continuous pressure of the top spring 23 can automatically compensate for the minute gaps caused by this wear, maintaining the original tight contact state and thus extending the service life of the mold under precision requirements.

[0041] During mold temperature rise operation, the difference in thermal expansion coefficients of different metal materials may cause changes in the mating clearance. The flexible preload of the spring can automatically adapt to these minute thermal deformations within a certain range, maintaining the system's working performance.

[0042] This invention adds a layer of precise linear guidance to the existing guiding mechanism of the limiting flange 12 and the limiting groove by setting a guide protrusion 22 and a receiving elongated groove 21. The sliding of the guide protrusion 22 within the receiving elongated groove 21 provides additional constraint along the direction of slider movement, further enhancing the rigidity and resistance to eccentric loads of the slider system in the direction of movement.

[0043] This utility model has a vertical slot 24 on the upper end face of the limiting seat 9, which communicates with the accommodating long slot 21. The top pressure spring 23 can be easily installed through the vertical slot 24.

[0044] The foregoing has shown and described the basic principles and main features of this utility model, as well as its advantages. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claims. The scope of protection of this utility model is defined by the appended claims and their equivalents.
