Description

Technical Field

[0001] The utility model relates to the technical field of injection molds, in particular to an injection mold capable of demoulding a product upside down in a limit space. Background Art

[0002] Injection molding, also known as injection molding, is a molding method that combines injection and molding. The advantages of injection molding are fast production speed, high efficiency, automated operation, a wide variety of colors and patterns, shapes from simple to complex, sizes from large to small, and precise product dimensions. Products are easy to update and can be made into parts with complex shapes.

[0003] Currently, when demolding a product's undercut, an additional drive source is required to separate the molds on both sides of the undercut so as to remove the restriction on the undercut and demold it. However, part of the undercut is located in the middle of the product, causing the demolding mechanism of this part to occupy a large space in the middle of the mold, making it difficult to fully utilize the mold space, resulting in an increase in the overall cost of the equipment.

[0004] Therefore, in view of this, the existing structure and defects are studied and improved, and an injection mold is provided that can demould the product in an inverted manner in an extreme space. Utility Model Content

[0005] The purpose of the utility model is to provide an injection mold that can demould a product upside down in a limit space, so as to solve the problems raised in the above background technology.

[0006] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: an injection mold that can demold a product in an extreme space by inverting it, comprising an upper mold base and a demolding assembly, the bottom of the upper mold base is connected to the lower mold base, and the bottom of the lower mold base is provided with a base, and a driving seat is provided in the middle of the top surface of the base, the demolding assembly is arranged on the top of the driving seat, the demolding assembly comprises a connecting seat, a rocker arm, a limiting groove, a limiting rod, a fixing sleeve and an inverted groove, the top of the connecting seat is rotatably connected to the rocker arm, and a limiting groove is provided on one side of the rocker arm, the inner sliding connection of the limiting groove is connected to the limiting rod, and the end of the limiting rod is connected to the fixing sleeve, and the top of the rocker arm is provided with an inverted groove.

[0007] Furthermore, the connecting seat is fixedly connected to the driving seat, and the connecting seat is slidably connected to the lower mold seat.

[0008] Furthermore, the swing rod is slidably connected to the lower mold base, and the upper width of the swing rod is greater than the middle width thereof.

[0009] Furthermore, the interior of the driving seat is slidably connected to a limiting column, and a top pin is fixed to the top of the driving seat.

[0010] Furthermore, the limiting column is fixedly connected to the lower die base, and the lower die base is slidably connected to the ejector pin.

[0011] Furthermore, a limiting assembly is provided on both sides of the lower die base, and the limiting assembly includes a fixing seat and a cylinder. The fixing seats are arranged on both sides of the lower die base, and one side of the fixing seat is connected to the cylinder.

[0012] Furthermore, the limiting assembly also includes a slide and a limiting block. The end of the cylinder is connected to the slide, and the limiting block is fixed on one side of the slide.

[0013] Furthermore, the limit block is slidably connected to the lower die base, and the limit block is consistent with the lower die base.

[0014] The utility model provides an injection mold that can demould a product upside down in an extreme space, which has the following beneficial effects:

[0015] 1. The utility model sets up the demoulding assembly. When the external power source drives the driving seat to move, the connecting seat can be moved synchronously. At this time, the swing rod will push the product and eject it from the inside of the lower mold base. When the end of the upper limit groove of the swing rod fits with the limit rod, the larger head of the swing rod will move out of the lower mold base. At this time, a gap will be generated between the waist of the swing rod and the lower mold base. The limit rod can squeeze the swing rod and rotate it to both sides, so that the swing rods on both sides of the inverted buckle on the product can be automatically separated. Therefore, during the demoulding process, the mold separation operation can be automatically performed without adding an additional power source. At the same time, the structure occupies a small space, is simple and practical, and is conducive to reducing equipment costs.

[0016] 2. The utility model sets a limit assembly, and the cylinder can push the slide so that the limit block is in close contact with the lower mold base. Therefore, during the injection molding process, a hook structure can be formed on the side of the product. After injection molding, the cylinder only needs to drive the slide to move back and reset, so that the limit block can be separated from the side of the product, thereby releasing the restriction on the product and avoiding affecting the subsequent demolding operation of the product. At the same time, the setting of multiple ejectors during demolding can make the overall force of the product uniform, thereby improving the effect of demolding. BRIEF DESCRIPTION OF THE DRAWINGS
