Description

Technical Field

[0001] The utility model relates to the technical field of injection molds, in particular to an injection mold for injection molded parts. Background Art

[0002] An injection mold is a tool for producing plastic products; it is also a tool that gives plastic products a complete structure and precise dimensions. Injection molding is a processing method used in mass production of certain parts with complex shapes. Specifically, it refers to the high-pressure injection of heated and molten plastic into the mold cavity by an injection molding machine, and after cooling and solidification, a molded product is obtained. When an existing injection mold is used for injection molding, a cooling channel is set inside it for cooling after injection molding.

[0003] When the upper and lower molds of existing injection molds for injection molded parts are opened, they are often taken out manually, which is time-consuming and labor-intensive, and is easy to damage the injection molded parts, resulting in low efficiency. Utility Model Content

[0004] The utility model aims to solve the problems in the background technology and provides an injection mold for injection molded parts.

[0005] In order to achieve the above purpose, the utility model adopts the following technical solutions:

[0006] An injection mold for injection molded parts, comprising a bottom plate, a bottom plate having a lower mold fixedly connected to the top, a mold groove being provided on the top of the bottom plate, two fixed columns being symmetrically fixedly connected to the top of the bottom plate, a top plate being fixedly connected to the top of the two fixed columns, an electric telescopic rod being fixedly connected to the top of the top plate, a driving end of the electric telescopic rod movably passing through the top of the top plate and fixedly connected to a lifting plate, and an upper mold being fixedly connected to the bottom of the lifting plate;

[0007] The jacking assembly includes a jacking plate movably fitted to the bottom of the mold groove, the bottom of the jacking plate is fixedly connected to a jacking column slidably inserted in the bottom of the mold groove, the bottom of the mold groove is provided with a groove matching the jacking column, the bottom of the groove and the bottom of the jacking column are commonly connected with a spring, the rear wall of the lower mold is fixedly penetrated by a pipe connected to the groove, an end of the pipe away from the lower mold is movably inserted with an air plug column, and the air plug column is located above the lifting plate.

[0008] Preferably, a circular plate is fixedly connected to the bottom of the gas plug column, and the bottom of the circular plate is attached to the top of the lifting plate.

[0009] Preferably, the lifting plates are slidably sleeved on the outer walls of the two fixing columns.

[0010] Preferably, four sides of the lifting plate are slidably fitted on the surface of the mold groove.

[0011] Preferably, the model of the electric telescopic rod is CAHB-10.

[0012] Compared with the existing technology, the advantages of the injection mold for injection molded parts are:

[0013] After the injection molded parts are formed, the lifting plate is driven upward by controlling the electric telescopic rod. When the lifting plate pushes the circular plate, the air plug column can be pushed upward in the pipeline. At this time, the jacking column in the groove can be pushed upward by squeezing the air in the pipeline. Finally, the injection molded parts in the lower mold can be pushed out through the jacking plate, so that the injection molded parts can be quickly removed and unloaded, thereby improving work efficiency.

[0018] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0019] Reference Figure 1-Figure 3 An injection mold for injection molded parts includes a bottom plate 1, a lower mold 2 is fixedly connected to the top of the bottom plate 1, a mold groove is opened on the top of the lower mold 2, two fixed columns 3 are symmetrically fixedly connected to the top of the bottom plate 1, a top plate 4 is fixedly connected to the top of the two fixed columns 3, an electric telescopic rod 5 is fixedly connected to the top of the top plate 4, and the model of the electric telescopic rod 5 is CAHB-10. The driving end of the electric telescopic rod 5 movably passes through the top of the top plate 4 and is fixedly connected to a lifting plate 6. The bottom of the lifting plate 6 is fixedly connected to an upper mold 7. The lifting plate 6 is slidably sleeved on the outer walls of the two fixed columns 3, which plays a guiding and limiting role on the lifting plate 6, so that the lifting plate 6 can be more stable when moving up and down.

[0020] The lifting assembly includes a lifting plate 8 movably fitted on the bottom of the mold groove. The four sides of the lifting plate 8 are slidably fitted on the surface of the mold groove to prevent the material in the mold groove from penetrating into the gap between the lifting plate 8 and the mold groove.

Finally, after the injection molded part in the lower mold 2 is formed, the lifting plate 6 is driven to move upward by controlling the electric telescopic rod 5. When the lifting plate 6 pushes the circular plate 14, the air plug column 13 can be pushed upward in the pipeline 12. At this time, the jacking column 9 in the groove 10 can be pushed upward by squeezing the air in the pipeline 12. Finally, the injection molded part in the lower mold 2 can be pushed out by the lifting plate 8, so that the injection molded part can be quickly removed and unloaded, thereby improving work efficiency.
