Embodiment 1

[0022] see figure 1 and 3 , in an embodiment of the present invention, an injection mold, an upper mold 4, a bottom plate 12 and a lower mold 20; the lower mold 20 is installed on the bottom plate 12, and the upper end of the bottom plate 12 is fixed with a crossbeam 2 through two symmetrically arranged brackets 1 , the upper mold 4 is driven by the driving assembly installed on the beam 2 to move up and down, the lower mold 20 is provided with a movable mold 9, and the movable mold 9 forms an injection flow channel with the upper mold 4 and the lower mold 20, so The lower end of the movable mold 9 is fixed with an annular block 11, and the annular block 11 is placed in the annular oil chamber 10 provided on the lower mold 20, and the annular oil chamber 10 communicates with the oil supply assembly. During the specific use process, the annular block 11 Placed in the annular oil chamber 10, the oil supply assembly absorbs the hydraulic oil in the annular oil chamber 10, so tha...

Embodiment 2

[0029] see figure 2 and 3 During the specific implementation process of the present invention, another embodiment is proposed to improve the present application. Specifically, the drive assembly includes a motor 16, a bidirectional threaded rod 17 and a threaded sleeve 18, and the bidirectional threaded rod 17 is arranged horizontally. And its two ends are respectively rotated and installed on the support 1, and the output shaft of the described motor 16 is connected with the described two-way threaded rod 17 by transmission belt, and two-way threaded rod 17 is symmetrically provided with two threaded sleeves 18, and the threaded sleeve 18 The lower end of the lower end is hinged with the upper end of the upper mold 4 through the connecting rod 19 hinged therewith. When the motor 16 drives the two-way threaded rod 17 to rotate, the upper mold 4 is driven to move vertically under the action of the threaded sleeve 18 and the connecting rod 19.

Abstract

The invention relates to the injection mold technology field, in particular to an injection mold. The injection mold comprises an upper mold, a bottom plate and a lower mold, wherein the lower mold isinstalled on the bottom plate, a beam is fixed at the upper end of the bottom plate through two supports which are symmetrically arranged, the upper mold is driven by a drive assembly installed on the beam to move up and down, a movable mold is arranged on the lower mold, the movable mold, the upper mold and the lower mold form an injection molding runner, an annular block is fixed at the lower end of the movable mold, the annular block is placed in an annular oil cavity formed in the lower mold, and the annular oil cavity communicates with an oil supply assembly. The injection mold is novelin design, uses the oil supply assembly for adsorbing hydraulic oil in the annular oil cavity, and thereby generates negative pressure in the annular oil cavity, and achieves fixation of the movable mold, and when the injection mold needs to be stripped, the oil supply assembly supplies the oil into the annular oil cavity, and achieves a pressurization function, and therefore an injection moldingproduct after being cooled is enabled to move up with the movable mold, and the molded product is convenient to fetch out.

Description

technical field [0001] The invention relates to the technical field of injection molds, in particular to an injection mold. Background technique [0002] Injection mold is a tool for producing plastic products; it is also a tool for giving plastic products complete structure and precise dimensions. Injection molding is a processing method used in the mass production of certain complex-shaped parts. Specifically, it refers to injecting the heated and melted plastic into the mold cavity under high pressure from the injection molding machine, and after cooling and solidifying, a molded product is obtained. [0003] Injection molds are divided into thermosetting plastic molds and thermoplastic plastic molds according to the molding characteristics; according to the molding process, they are divided into transfer molds, blow molds, casting molds, thermoforming molds, hot compression molds (compression molds), injection molds, etc. Among them, the hot pressing mold can be divide...
