Detailed implementation manners

[0018] The technical solution of the present invention will be specifically described below with reference to the accompanying drawings.

[0019] The structure of the electrical mold is as Figure 1 and Figure 2 shown, mainly composed of components such as mold base 1, precision positioning block 2, cooling water channel 3, front mold core 4, cold air duct 5, steam pipe joint 6, cold air-steam pipe adapter 7, mold base heat preservation water channel 8, inclined guide pillar 9, mold core inclined beam block 10, mold core heat insulation board 11, mold core steam pipe 12, slider base 13, slider insert and body 14, rear mold core 15, exhaust insert 16, etc.

[0020] The front mold core and the rear mold core are installed on the mold base, and the front and rear mold cores are closed together to form a mold cavity.

[0021] There is a pair of slider insert and body and inclined guide pillar respectively, distributed on both sides of the front and rear mold cores. The top of the inclined guide pillar is installed on the top of the mold base, and the slider insert and body and the slider base are installed at the bottom of the inclined guide pillar. The inclined guide pillar rotates around the top, driving the slider insert and body to slide forward and backward to the front and rear mold cores, fitting on both sides of the front and rear mold cores to fix the mold cavity. The slider base slides down along the inclined guide pillar to lock the slider insert and body, preventing the mold cavity from deforming due to the thermal expansion and contraction of the mold core, and further causing the deformation of the product.

[0022] The mold base heat preservation water channel communicates with the inside of the mold base and leads to the mold cavity, injecting hot water into the inside of the mold base to keep the temperature of the mold cavity at a set value, and injecting plastic into the mold cavity to form a product.

[0023] The mold core heat insulation board is installed at the bottom of the rear mold core to prevent heat transfer between the rear mold core and the mold base, so that the mold maintains a good heat preservation effect during production and processing, which is beneficial to the molding of plastic.

[0024] The mold core steam pipe is located above the front mold core, in the shape of a capillary tube, covering the front mold core, and connecting the steam pipe joint and the cold air-steam pipe adapter.

[0025] Inject high-temperature steam into the steam pipeline of the mold core through the steam pipe joint, quickly and evenly heat the surface of the front mold core to 150 degrees, rapidly heat the surface of the plastic product, then stop the water circulation for heat preservation in the mold base and inject hot water into the mold base. Inject cold water into the steam pipeline of the mold core through the cold air-steam pipe adapter, quickly and evenly cool the surface of the front mold core, rapidly cool the surface of the plastic product. Through rapid cooling and heating, a super-high mirror surface effect is produced on the mold surface, eliminating the need for post-spraying processing.

[0026] The inclined beam block and precision positioning block of the mold core are arranged around the front mold core to lock the front mold core and prevent the front mold core from deforming and moving due to thermal expansion and contraction.

[0027] The exhaust insert is installed on the rear mold core to discharge the gas in the mold cavity, keep the air pressure in the mold cavity at the set value, and prevent the product from cracking.

[0028] The cooling water circulation and cold air pipeline are connected to the inside of the mold base to inject cold water and cold air into the mold cavity, reduce the temperature of the mold cavity, cool and dry the plastic product, integrating multiple processes in a set of molds to save costs and time.

[0029] The above are embodiments of the present invention and do not limit the present invention. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention are all included in the protection scope of the present invention.
