[0027] Embodiments:

[0028] The following will be further described in detail in combination with the drawings of the embodiments of the present application. Figure 1

[0029] The embodiments of the present application disclose a surface chromium-plated demolding structure, comprising a B plate 1, a pipe mold is clamped on the B plate 1, the B plate 1 is provided with a sliding block 2 at both ends of a pipe mold insert 4, and the sliding block 2 is detachably connected with both ends of the pipe mold; the surface of the pipe mold is treated by chromium plating.

[0030] Referring to Figure 1 , Figure 2 and Figure 3 , the pipe mold comprises a rear mold core 3 and an insert 4, and the insert 4 is clamped in the rear mold core 3; the pipe mold is designed in the form of combination of the rear mold core 3 and the insert 4, which facilitates the processing and manufacturing of the pipe mold and subsequent maintenance, and when the insert 4 or the rear mold core 3 is damaged or needs to be replaced, it can be operated separately, thereby reducing the maintenance cost and replacement difficulty.

[0031] Referring to Figure 1 , Figure 2 and Figure 3 ​, the insert 4 is divided into two parts including a front end and a rear end, the diameter of the front end is smaller than that of the rear end, and the diameter of the rear end is the same as that of the rear core 3; the rear end is detachably connected with the slider 2; the product can be more smoothly separated from the mold during demolding, the demolding resistance is reduced, and the product is prevented from being damaged due to poor demolding; meanwhile, the detachable connection between the rear end and the slider 2 facilitates the assembly and disassembly between the insert 4 and the slider 2.

[0032] Referring to Figure 1 , Figure 2 and Figure 3 , the connecting section between the front end and the rear end is a slope; the rear core 3 and the insert 4 are facilitated to be disassembled and assembled, and meanwhile, the product is facilitated to be smoothly transitioned during demolding, stress concentration is avoided to cause damage to the product, and the success rate and quality of product demolding are further improved.

[0033] Referring to Figure 1 and Figure 2 , the side surface and the front surface of the slider 2 are respectively provided with a horizontal hole and a vertical hole, and the horizontal hole is higher than the vertical hole; the horizontal hole and the vertical hole can be used for installing positioning pins, connecting bolts and other components during mold assembly and use, the stability and accuracy of the connection between the slider 2 and other mold components are improved, and the reliability of the overall structure of the mold is ensured; through the design of the height difference, the connection and movement relationship inside the mold can be more reasonably planned, so that the components do not interfere with each other during work, and the accuracy and reliability of the mold action are ensured.

[0034] The implementation principle of the surface chromium plating demolding structure in the embodiment of the application is that: during the workpiece forming process in the mold, A plate and B plate 1 are usually divided, and the A plate and the B plate form a closed mold cavity after being combined; the melt is accurately injected into the mold cavity composed of the B plate, the pipe mold and the slider 2 through the flow channel system, and the melt uniformly fills each corner in the cavity, fully replicates the shape and size characteristics of the cavity, and after the melt is cooled and solidified for a certain time, the product with the expected shape and structure is formed.

[0035] During demolding, the B plate is fixed, and the A plate is removed, at this time, the workpiece is exposed. The slider 2 starts to move under the drive of a demolding power source (such as a hydraulic cylinder or a mechanical ejection device), and the movement of the slider 2 drives the pipe mold insert 4 to move outward due to the detachable connection relationship between the slider 2 and the rear end of the pipe mold insert 4; the chromium plating layer on the surface of the pipe mold has extremely low surface roughness and good chemical stability, which can effectively reduce the intermolecular force and friction force between the workpiece and the surface of the pipe mold, so that the adhesion probability of the workpiece and the pipe mold is greatly reduced.

[0036] In the process of tube mold separation, if there is slight adhesion between the workpiece and the tube mold, the chromium plating layer can also play a role in lubrication and separation, ensuring that the workpiece can be smoothly separated from the tube mold. After the tube mold is separated, the workpiece is generally left in the B plate 1, at which time the workpiece can be conveniently taken out by manual or automatic workpiece taking device; even in special cases, the workpiece is sleeved on the rear mold core 3, due to the presence of the chromium plating layer, the friction between the two is significantly reduced, and the operator only needs to exert a small external force to smoothly take down the workpiece, the entire demolding process is efficient and stable, effectively avoiding product damage and low production efficiency caused by difficult demolding and other problems.

[0037] The chromium plating process greatly improves the surface quality of the product, making the surface smoother and more flat, with good gloss and corrosion resistance, which can meet the application scenarios that require high product appearance and durability.

[0038] In the production process, due to the chromium plating layer reducing the product sticking to the mold, not only reduces the defective rate, but also greatly shortens the demolding time of a single product, thereby improving the injection molding cycle by 30%, significantly improving the production efficiency. Furthermore, when the product needs to be adjusted or improved in size, due to the unique structural design of the tube mold (the combination form of the rear mold core and the insert), only partial modification or replacement of the insert or the rear mold core is needed, without the need to re-make the entire mold, greatly reducing material costs and secondary processing costs, and reducing production costs.

[0039] The ingenious connection design between the parts of the tube mold (such as the shape design of the front end and the rear end of the insert, the connection method of the slider and the insert, etc.) and the special layout of the horizontal hole and the vertical hole on the slider together ensure the accuracy, stability and reliability of the mold during the mold opening and closing and demolding process, effectively improving the molding quality of the product, reducing product defects caused by unreasonable mold structure, and providing a strong guarantee for the production of high-quality products.

[0040] The above are preferred embodiments of the present application, and are not intended to limit the protection scope of the present application, therefore: any equivalent changes made in accordance with the structure, shape, principle of the present application shall be covered within the protection scope of the present application.
