Problems solved by technology

[0003] The current injection mold structure is prone to problems such as scorch marks and flow marks on products due to poor exhaust
In addition, the current injection mold parts usually have difficulties such as the water channel cannot be processed or the product cannot be evenly distributed by the water channel.
As a result, the product production cycle cannot be effectively reduced, resulting in reduced profits

Embodiment

[0019] Such as figure 1 As shown, a low-cost and high-efficiency injection mold is used for molding injection molded parts 3. The injection mold includes a fixed mold and a movable mold, and the fixed mold is provided with a first male mold core 1 and the second male mold core 2, the first male mold core 1 is detachably connected to the second male mold core 2, and the first male mold core 1 is connected to the injection molded part 3 to be formed.

[0020] The first male mold core 1 and the second male mold core 2 are fixed by screws and combined and polished together. A gap for gas discharge is provided between the first male mold core 1 and the second male mold core 2 . The second male mold core 2 is provided with a cooling water inlet channel 21 and a drainage channel 22 communicating with the first male mold core 1; the cooling water enters from the water inlet channel of the second male mold core 2 and passes through the first male core After the mold core 1 evenly cir...

Abstract

The invention relates to a low-cost high-forming-efficiency injection mold which is used for forming of plastic injection parts. The injection mold comprises a mold fixed die and a mold movable die. The mold fixed die is provided with a first core insert and a second core insert. The first core insert is detachably connected with the second core insert. The first core insert is connected with the plastic injection parts to be formed. Compared with the prior art, the low-cost high-forming-efficiency injection mold has the advantages that the mold forming efficiency is improved, and the production cost is greatly lowered.

Description

technical field [0001] The invention relates to an injection mold, in particular to an injection mold with low cost and high molding efficiency. 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 material into the mold cavity by high pressure, and after cooling and solidifying, a molded product is obtained. [0003] The current injection mold structure is prone to problems such as scorch marks and flow marks on products due to poor exhaust. In addition, the current injection mold parts usually have difficulties such as the water channel cannot be processed or the product cannot be evenly distributed by the water channel. As a result, the product production cycle cannot be effectively reduced...
