Description

Technical Field

[0001] This utility model relates to the field of injection molding die technology for pipe fittings, and in particular to a slider core-pulling structure for injection molding die fittings. Background Technology

[0002] In injection molding pipe fittings, some molds design both the cavity and the core on the slider, and separate the core using multiple sliders to achieve the product shape as required by the design. This is especially true for products with multiple through holes around the perimeter. However, when designing the product, if there are inverted mold structures or lettering on the outside of the through holes that are not conducive to demolding, conventional slider direct pull demolding will damage or destroy these designs. Therefore, it is necessary to separate the cavity part and the core part on the slider by a certain distance before or during the core pulling process to ensure smooth product demolding. Utility Model Content

[0003] To address the aforementioned problems, this utility model aims to provide a slider core-pulling structure for injection molded pipe fittings, which can solve the problems of products with inverted mold design being difficult to demold and prone to surface damage during demolding.

[0004] The technical problem solved by this utility model can be achieved by the following technical solution: a slider core-pulling structure for injection molding pipe fittings, including a slider base, a cavity slider, a core, a positioning pin, a guide hole, and a moving template. The moving template is provided with a groove, and the lower part of the slider base is disposed in the groove, allowing the slider base to slide within the groove. Two cavity sliders are symmetrically arranged on the inner side of the slider base, and the cavity sliders are slidably connected to the slider base. The core is fixed on the slider base and is located between the two cavity sliders. A positioning pin is provided at the bottom of the cavity slider, and a guide hole is provided on the moving template, with the positioning pin disposed within the guide hole.

[0005] The moving template has two symmetrical guide holes, which extend outward in a V-shape to the groove of the slider base.

[0006] The slider base is provided with an I-shaped guide slide, the cavity slider is provided with an I-shaped groove, the I-shaped guide slide is disposed in the I-shaped groove, and the cavity slider can slide on the I-shaped guide slide.

[0007] The I-shaped guide rail is fixed to the slider base by screws.

[0008] Guide rods are provided on both sides of the slider base. The ends of the guide rods are set in the guide grooves of the inclined guide plate. The guide rods can slide in the guide grooves. The inclined guide plate is fixed to the side of the fixed template.

[0009] The bottom of the slider base is provided with a sliding groove, and the sliding plate of the moving template is provided in the groove. The slider base is slidably connected to the slider plate through the sliding groove.

[0010] Compared with the prior art, this utility model has the following advantages: This utility model is applicable to products with inverted mold design and text design on the surface. During core pulling and demolding, the two cavity sliders will be guided by the guide hole and separated to both sides by a certain distance along the I-shaped guide strip, reducing the clamping force of the mold on the product, greatly reducing the pulling force on the product when the slider pulls the core, preventing damage or destruction to the product surface, and reducing the difficulty of product demolding; and the gap generated after the separation of the two cavity sliders can be used to add appearance component design to the product, which is applicable to most injection molds.

[0019] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the following description, in conjunction with specific illustrations, further elaborates on this utility model.

[0020] In the description of this utility model, it should be understood that the terms "one end", "the other end", "outer side", "upper", "inner side", "horizontal", "coaxial", "center", "end", "length", "outer end", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the drawings. They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0021] Combined with appendix Figures 1 to 7 As shown, this embodiment discloses a slider core-pulling structure for injection molded pipe fittings, including a slider base 4, cavity sliders 7, cores 13, positioning pins 10, guide holes, and a moving template 12. The moving template 12 is provided with a sliding groove, and the lower part of the slider base 4 is disposed within the sliding groove 14, allowing the slider base 4 to slide within the sliding groove 14. Two cavity sliders 7 are symmetrically arranged on the inner side of the slider base 4, and the cavity sliders 7 are slidably connected to the slider base 4. The core 13 is fixed to the slider base 4 and located between the two cavity sliders 7. A positioning pin 10 is provided at the bottom of each of the two cavity sliders 7. The moving template 12 is provided with a guide hole 11, and the positioning pin 10 is disposed within the guide hole 11.

[0022] Two guide holes 11 are symmetrically arranged on the moving template 12. The two guide holes 11 extend outward in a V-shape to the slide groove 14 of the slider base 4. The function of the guide holes 11 is to control the sliding direction of the positioning pin 10 to control the sliding opening and closing of the two cavity sliders 7 on the I-shaped guide slide. The angle and length of the guide holes 11 determine the sliding distance of the two cavity sliders 7. When the mold is opened, the inclined guide plate 3 drives the slider base 4 to move outward. The slider base 4 pulls the cavity slider 7. The positioning pin 10 at the bottom of the cavity slider 7 moves along the inclined angle of the guide hole 11, thereby driving the cavity slider 7 to slide to both sides along the I-shaped guide slide 6, so that the two cavity sliders 7 are separated by a certain distance.

[0023] The slider base 4 is provided with an I-shaped guide slide 6, which is fixed to the slider base 4 by an internal hex screw. The cavity slider 7 is provided with an I-shaped groove, and the I-shaped guide slide 6 is disposed in the I-shaped groove, so that the two cavity sliders 7 can slide on the I-shaped guide slide 6.

[0024] Guide rods are provided on both sides of the slider base 4. The ends of the guide rods are set in the guide groove of the inclined guide plate 3. The guide rods can slide in the guide groove. The inclined guide plate 3 is fixed to the side of the fixed template 2.

[0025] The bottom of the slider base 4 is provided with a sliding groove 8, and the sliding plate 5 is provided in the groove 14 of the moving template 12. The slider base 4 is slidably connected to the sliding plate 5 through the sliding groove 8.

[0026] When the mold opens, the inclined guide plate 3 drives the slider base 4 to move outward. The slider base 4 pulls the cavity slider 7. Under the combined action of the inclined guide hole 11 and the I-beam guide slide 6, the two cavity sliders 7 separate a certain distance from each other. When the two cavity sliders 7 separate, the pulling force on the product during core pulling is greatly reduced, preventing damage or destruction to the product surface and reducing the difficulty of demolding. The gap created after the two cavity sliders separate can be used to add appearance component designs to the product. According to the product design requirements, some trademarks or product structures that would otherwise affect demolding can be designed on the cavity sliders. It is widely applicable to various injection molds.

[0027] The above description is merely a preferred embodiment of the present utility model and does not constitute any limitation on the utility model. Any simple modifications, equivalent changes, or alterations made to the above embodiments based on the technical principles of the present utility model shall still fall within the scope of the technical solution of the present utility model.
