Description

Injection mold

[ technical field ]

The utility model relates to an injection mold.

[ background art ]

In the existing injection mold for injection molding of knob keys and measuring cups, cavities of the injection mold are transversely arranged, so that distance difference exists between each cavity and an injection port, and therefore, the cavities are difficult to realize pressure balance during injection molding. Therefore, when the existing injection mold for injection molding of the knob key and the measuring cup is used for injection molding, the injection molding equipment is required to have higher injection pressure and stronger mold locking capacity.

[ contents of utility model ]

The utility model overcomes above-mentioned technique is not enough, provides an injection mold.

In order to achieve the above purpose, the utility model adopts the following technical scheme:

an injection mold, its characterized in that: including base, lower module, go up the module, be equipped with the mouth of moulding plastics on going up the module top surface, form a plurality of die cavities between lower module and the last module, the die cavity respectively with mould plastics mouthful intercommunication and around the mouthful circumference of moulding plastics evenly set up, be equipped with the ejecting mechanism who opens the upper module and release the mould on the base.

An injection mold as above, characterized in that: the die cavity consists of a die cavity arranged on the upper die set and a die core arranged on the lower die set.

An injection mold as above, characterized in that: the bottom surface of the upper die set is provided with a runner between the injection molding port and the die cavity.

An injection mold as above, characterized in that: the push-out mechanism comprises a lifting frame arranged on the base, a push block used for pushing the mold out of the mold core is arranged on the lower mold unit, a mold core through hole is formed in the push block, the mold core is arranged in the mold core through hole, and the lifting frame is connected with an upper mold ejector rod used for jacking the upper mold unit and a push block ejector rod used for jacking the push block.

The utility model has the advantages that:

the utility model discloses form a plurality of die cavities between lower module and last module, the mould die cavity simultaneously with the mouth intercommunication of moulding plastics and around moulding plastics a mouthful circumference even setting, form and use the mouth of moulding plastics as the circular array at center, the pressurized equilibrium between each die cavity when consequently moulding plastics, fashioned mould is complete, and need not to improve injection moulding device's injection pressure and mode locking ability.

[ detailed description of the invention ]

The following description is further detailed with reference to the accompanying drawings and embodiments of the present invention:

as shown in fig. 1-5, an injection mold comprises a base 1, a lower module 2, and an upper module 3, wherein an injection port 31 is provided on the top surface of the upper module 3, a plurality of cavities are formed between the lower module 2 and the upper module 3, the mold cavities are respectively communicated with the injection port 31 and uniformly arranged around the circumference of the injection port 31, a push-out mechanism for opening the upper module 3 and pushing out the mold is provided on the base 1, and a runner 34 is provided on the bottom surface of the upper module 3 and between the injection port 31 and the mold cavity 32. When the injection molding port 31 of the upper module 3 is used for injection molding, injection molding materials enter a cavity formed between the lower module 2 and the upper module 3 through the injection molding port 31 and the runner 34, and each cavity is uniformly arranged around the circumference of the injection molding port 31 to form a circular array taking the injection molding port as the center, so that the compression between the cavities is balanced during injection molding, a formed mold is complete, and the injection pressure and the mold locking capacity of injection molding equipment are not required to be improved.

As shown in fig. 2-4, the cavity is comprised of a mold cavity 32 disposed on the upper die set 3 and a mold core 33 disposed on the lower die set 2.

As shown in fig. 1 to 5, the pushing mechanism includes a lifting frame 41 disposed on the base 1, a pushing block 42 for pushing the mold out of the mold core 33 is disposed on the lower mold unit 2, a core through hole is disposed on the pushing block 42, the mold core 33 is disposed in the core through hole, and the lifting frame 41 is connected to an upper mold carrier rod 43 for lifting the upper mold unit 3 and a pushing block carrier rod 44 for lifting the pushing block 42. After the mold is formed, the lifting frame 41 is lifted upwards to drive the upper mold mandril 43 and the ejector block mandril 44 to move upwards, so that the upper mold set 2 and the ejector block 42 are lifted, and the forming mold on the mold core 33 is pushed out through the ejector block 42.
