Description

Technical Field

[0001] This utility model relates to the field of household appliance injection mold technology, and in particular to a household appliance injection mold that facilitates accurate mold closing. Background Technology

[0002] Injection molds are tools used to produce plastic products; they also give plastic products their complete structure and precise dimensions. Injection molds are a processing method used in the mass production of parts, mainly in the industrial field. The injection molding process involves injecting molten material under high pressure into the mold cavity, which then cools and solidifies to obtain the molded product. Based on molding characteristics, injection molds are classified into two types: thermosetting plastic molds and thermoplastic plastic molds.

[0003] Appliance casings are typically manufactured using injection molds. These molds usually consist of two parts: an upper mold and an lower mold. During injection molding, the two molds need to be closed. However, existing mold-closing processes generally lack devices to limit the stroke, which can easily lead to positional misalignment between the two molds during movement, thus affecting the mold closure. Utility Model Content

[0004] The purpose of this invention is to overcome the shortcomings of the existing technology. By having two rotating plates push two sliders to move on the outer wall of the slide rod, multiple rotating plates limit the mold closing operation again, ensuring the accuracy of mold closing. At the same time, the movement of the two sliders compresses the spring, causing the spring to deform. The reaction force provided by the spring acts on the slider, thereby buffering the reaction force during mold closing and reducing the impact force brought about by mold closing. This invention provides a household appliance injection mold that facilitates accurate mold closing.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] An injection mold for home appliances that facilitates accurate mold closing includes a base, a lower mold at the upper end of the base, a plurality of symmetrically arranged support rods at the upper end of the base, a top plate at the upper end of the plurality of support rods, two symmetrically arranged telescopic cylinders passing through the top plate, a movable plate at the telescopic ends of the two telescopic cylinders, an upper mold that cooperates with the lower mold at the lower end of the movable plate, a positioning mechanism for positioning the upper mold and the lower mold at the lower end of the movable plate, and a guiding mechanism for guiding the movable plate at the upper end of the base.

[0007] Preferably, the positioning mechanism includes a plurality of symmetrically arranged insert rods disposed at the lower end of the moving plate, and the outer walls of the plurality of insert rods are provided with a plurality of circumferentially arranged limiting grooves.

[0008] Preferably, the guiding mechanism includes a groove formed on the upper end of the base, and two symmetrically arranged sliders are slidably connected in the groove. The upper ends of the two sliders and the lower ends of the moving plate are each provided with a rotating seat, and the sliders are rotatably connected to each other through the rotating plate.

[0009] Preferably, a sliding rod is provided in the groove, the sliding rod passes through two sliders and is slidably connected to them, the sliders and the groove are elastically connected by a spring, and the spring is sleeved on the outer wall of the sliding rod.

[0010] Preferably, the upper end of the lower mold has a plurality of symmetrically arranged slots, and the inner walls of the plurality of slots are provided with a plurality of limiting strips, and the plurality of limiting strips respectively cooperate with a plurality of limiting slots.

[0011] Preferably, the movable plate is provided with a plurality of symmetrically arranged sleeves, which are respectively sleeved on the outer wall of a plurality of support rods and slidably connected thereto.

[0012] The beneficial effects of this utility model are:

[0013] 1. The mold closing is initially limited by the sliding connection of multiple sleeves and support rods. Then, the mold closing operation is further limited by the cooperation of multiple insert rods and slots, as well as the cooperation of multiple limit grooves and limit strips between them.

[0014] 2. By having two rotating plates push two sliders to move on the outer wall of the slide bar, multiple rotating plates limit the mold closing operation again, ensuring the accuracy of mold closing.

[0021] Reference Figure 1-3 A household appliance injection mold for easy and accurate mold closing includes a base 1, a lower mold 2 at the upper end of the base 1, a plurality of symmetrically arranged support rods 3 at the upper end of the base 1, a top plate 4 at the upper end of the plurality of support rods 3, two symmetrically arranged telescopic cylinders 5 passing through the top plate 4, a moving plate 6 at the telescopic ends of the two telescopic cylinders 5, an upper mold 8 cooperating with the lower mold 2 at the lower end of the moving plate 6, and a positioning mechanism at the lower end of the moving plate 6 for positioning the upper mold 8 and the lower mold 2. The positioning mechanism includes a plurality of symmetrically arranged insert rods 17 at the lower end of the moving plate 6, and a plurality of circumferentially arranged limiting grooves 18 are opened on the outer wall of the plurality of insert rods 17.

[0022] The upper end of the movable plate 6 and the base 1 is provided with a guide mechanism for guiding the movable plate 6. The guide mechanism includes a groove 9 opened on the upper end of the base 1. Two symmetrically arranged sliders 11 are slidably connected in the groove 9. The upper end of the two sliders 11 and the lower end of the movable plate 6 are provided with rotating seats 12. The rotating seats 12 are rotatably connected to each other through rotating plates 13. By making the two rotating plates 13 push the two sliders 11 to move on the outer wall of the slide rod 10, the multiple rotating plates 13 limit the mold closing operation again, ensuring the accuracy of mold closing. At the same time, the two sliders 11 move and compress the spring 14, causing the spring 14 to deform. The reaction force provided by the spring 14 acts on the slider 11, thereby buffering the reaction force during mold closing and reducing the impact force brought about by mold closing.

[0023] The groove 9 is provided with a slide rod 10, which passes through two sliders 11 and is slidably connected to them. The sliders 11 and the groove 9 are elastically connected by a spring 14, which is sleeved on the outer wall of the slide rod 10.

[0024] The upper end of the lower mold 2 has multiple symmetrically arranged slots 15, and the inner walls of the multiple slots 15 are provided with multiple limiting strips 16, which respectively cooperate with multiple limiting grooves 18.

[0025] Multiple symmetrically arranged sleeves 7 are provided through the movable plate 6. The multiple sleeves 7 are respectively sleeved on the outer wall of multiple support rods 3 and slidably connected to them. Through the sliding connection between the multiple sleeves 7 and the support rods 3, the mold closing is initially limited. Then, by using the cooperation of multiple insert rods 17 and slots 15, and the cooperation of multiple limiting grooves 18 and limiting strips 16 between them, the mold closing operation is limited a second time.

[0026] When this utility model is in use, when closing the upper mold 8 and the lower mold 2, two telescopic cylinders 5 are activated, causing the telescopic ends of the two telescopic cylinders 5 to push the moving plate 6 to move, so that the moving plate 6 moves the upper mold 8 downward, so that the upper mold 8 and the lower mold 2 overlap, thereby realizing the closing of the upper mold 8 and the lower mold 2. The initial limiting of the mold closing is achieved by the sliding connection of multiple sleeves 7 and support rods 3. Then, the secondary limiting of the mold closing operation is achieved by the cooperation of multiple insert rods 17 and slots 15, as well as the cooperation of multiple limiting grooves 18 and limiting strips 16 between them.

[0027] Through the rotational connection between the multiple rotating seats 12 and the rotating plate 13 between the moving plate 6 and the groove 9, and the sliding connection between the slider 11 and the slide rod 10, the downward movement of the moving plate 6 causes the angle of the two rotating plates 13 to change, thereby causing the two rotating plates 13 to push the two sliders 11 to move on the outer wall of the slide rod 10. Thus, the multiple rotating plates 13 limit the mold closing operation again, ensuring the accuracy of mold closing. At the same time, the movement of the two sliders 11 compresses the spring 14, causing the spring 14 to deform. The reaction force provided by the spring 14 acts on the slider 11, thereby buffering the reaction force during mold closing and reducing the impact force brought about by mold closing.

[0028] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
