A slider (3) is provided in the middle position of the moving mold core (2), and a slider insert (4) is provided in the middle position of the slider (3). The slider (3) and the slider insert (4) are fixed on the slider body (9). Two stepped bolts (7) are symmetrically arranged on the slider (3). The stepped bolts (7) and the slider body (9) are connected by a spring (5) to achieve an adjustable stroke S. Slider guide rails (8) are provided on both sides of the slider body (9). This utility model eliminates product deformation caused by complex side hole shapes by secondary demolding of the slider. It can realize the injection molding mass production of complex side hole products without worrying about product deformation defects. The overall structure is compact, stable and reliable.

Description

Technical Field

[0001] This utility model relates to the field of injection mold technology, and in particular to a slider secondary demolding structure. Background Technology

[0002] In injection mold design, it is common to encounter products with complex holes on the sides, such as... Figure 3 As shown, if a traditional slider structure is used, the product is easily deformed due to the excessive sticking force of the hole, making mass production impossible. Summary of the Invention

[0003] The purpose of this invention is to provide a secondary demolding structure for a slider to solve the above-mentioned problems.

[0004] To achieve the above objectives, the technical solution adopted by this utility model is as follows: A secondary demolding structure for a slider includes a moving mold core and a slider body. A slider is provided at the middle position of the moving mold core, and a slider insert is provided at the middle position of the slider. The slider and the slider insert are fixed on the slider body. Two stepped bolts are symmetrically arranged on the slider. The stepped bolts and the slider body are connected by a spring to achieve an adjustable stroke S. Slider guide rails are provided on both sides of the slider body.

[0005] As a preferred technical solution, the slider and slider insert are fixed to the slider body by screws.

[0006] As a preferred technical solution, the adjustable stroke S is 0-10mm.

[0007] This utility model divides the traditional slider into two parts: the slider and the slider insert. In addition to molding the product, the slider insert also serves as a guide rail, enabling the slider to move smoothly. Step bolts are provided, and there is a stroke S between them and the slider body. Two step bolts and springs are provided to precisely control the demolding sequence and demolding stroke.

[0008] Compared with the prior art, the advantages of this utility model are: this utility model eliminates product deformation caused by complex side hole shape by secondary demolding of the slider, and can realize the injection molding mass production of complex side hole products without worrying about product deformation defects. The overall structure is compact, stable and reliable. Attached Figure Description

[0010] The present invention will be further described below with reference to the embodiments.

[0011] Example: See Figure 1 and Figure 2 A secondary demolding structure for a slider includes a moving mold core 2 and a slider body 9. A slider 3 is provided at the middle position of the moving mold core 2, and a slider insert 4 is provided at the middle position of the slider 3. The slider 3 and the slider insert 4 are fixed to the slider body 9 by screws 6. Two stepped bolts 7 are symmetrically arranged on the slider 3. The stepped bolts 7 and the slider body 9 are connected by a spring 5 to achieve an adjustable stroke S, which is 0-10mm. Slider guide rails 8 are provided on both sides of the slider body 9. In the mold closed state, such as Figure 1 As shown, the step bolt 7 and the slider body 9 are connected by a spring 5 with a travel S of 10mm. The slider guide rail 8 and the limit screw 10 have the same function as the traditional slider. That is, the slider guide rail 8 is to ensure the smooth sliding of the slider body 9, and the limit screw 10 is a safety measure to prevent the slider body 9 from coming out of the mold. When opening the mold, such as Figure 2 As shown, the slider insert 4 is driven by the slider body 9 to first move backward and separate from the product 1 (the product 1 is fixed in the middle position of the mold core 2), while the slider 3 is temporarily stationary under the action of the spring 5. When the slider body 9 moves a certain distance, the stroke S becomes 0. The slider 3 is driven to move backward together with the step bolt 7 to separate from the product 1, thus completing the demolding.

[0012] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
