[0002] The injection mold consists of two parts, the movable mold and the fixed mold. The movable mold is installed on the movable template of the injection molding machine, and the fixed mold is installed on the fixed template of the injection molding machine. During injection molding, the movable mold and the fixed mold are closed to form a gating system and Cavity, when the mold is opened, the movable mold and the fixed mold are separated for easy removal plastic products , but the gate of the traditional injection mold is easy to have plastic, which will cause the gate to be blocked. It needs to be cooled and then stop working. The staff will clean it up and treat it as waste, which not only wastes time and manpower, but also wastes raw materials; Stuck at the fixed mold, the staff needs to knock the fixed template with a copper rod to make the product fall, which delays production efficiency and wastes manpower; while the injection mold needs to work in a dust-free environment, if dust enters the raw material, the product will have quality problems

Embodiment 1

[0010] The invention is a high-efficiency injection mold for a plastic casing, which includes a dust cover 1, a fixed template seat 2, a fixed template 3, a guide post 4, a movable template 5, a support plate, 6 cushion blocks 7, a movable mold bottom plate 8, and a pouring plate. Port 9, positioning ring 10, condensation pipe 11, cavity 12, inner core 13, positioning screw plug 14, push plate 15, ejector rod 16, nitrogen spring 17, inclined ejector rod 18, hollow insulation plate 19, ceramics Heating device 20, a gate 9 is provided in the middle of the fixed template seat 2, a positioning ring 10 is provided above the gate 9, a dust cover 1 is provided above the positioning ring 10, and the outer side of the gate 9 is wrapped by a ceramic heating device 20, and the ceramic heating device 20 One end is connected to the hollow insulation board 19, the fixed formwork 3 is installed under the fixed formwork seat 2, the guide post 4 is installed under the fixed formwork 3, the supp...

Embodiment 2

[0012] The raw material enters the gate 9 through the dust cover 1. The dust cover 1 can prevent dust from entering the process of the raw material entering the gate 9. The raw material flows into the cavity 12 through the gate 9. After the cavity 12 is filled, the condenser 11 is cooled. After the raw material is cooled, the mold is opened, the nitrogen spring 17 moves the ejector rod upward to eject the product, and the inclined ejector rod 18 ejects downward, so that the product is separated from the fixed template 3 to prevent the product from being stuck on the fixed template 3; when adding raw materials again The ceramic heating device 20 works first to heat the raw material stored at the gate 9 to a molten state, so that it flows into the cavity 12 for reuse, which not only avoids the waste of raw materials, but also avoids the blockage of the gate 9; The temperature insulating plate 19 can effectively block the temperature, and avoid the temperature rise of the condensa...

Abstract

The invention provides a high-efficiency injection mold for a plastic case. The high-efficiency injection mold comprises a fixed mold plate seat, a fixed mold plate and the like. The high-efficiency injection mold is characterized in that the injection mold further comprises an angle ejector rod, a dust shield, a ceramic heating device and a hollow insulating plate, wherein the middle part of the fixed mold plate seat is provided with a sprue; a positioning loop is arranged above the sprue; the dust shield is mounted above the positioning loop; the outer side of the sprue is coated by the ceramic heating device; one end of the ceramic heating device is connected with the hollow insulating plate; the fixed mold plate is mounted below the fixed mold plate seat; a guide pillar is mounted below the fixed mold plate; a supporting plate is installed below the guide pillar; a cushion block is arranged below the supporting plate; an inner core is mounted above the supporting plate; and a cavity is located above the inner core. According to the invention, the dust shield can prevent dust from entering the sprue; the angle ejector rod can prevent a product from being stuck at the fixed mold plate; the ceramic heating device can prevent obstruction of the sprue and reduce waste of raw materials; and the hollow insulating plate can prevent the ceramic heating device from influencing raw materials in the cavity.
