[0033] Example

[0034] like Figure 1 The steam engine boiler housing 80 shown is hollow inside and has a through hole 802 connected to the inside on one side. The outer surface of the steam engine boiler housing 80 is provided with protruding ribs 801 in a circumferential direction from top to bottom.

[0035] Reference Figure 2-7 As shown, the utility model discloses a multi-side molding mold structure, including a panel 10, an upper pad 20, an upper movable mold 30, a lower fixed mold 40, a lower pad 50, an ejector plate 60 and a bottom plate 70 from top to bottom, a groove 301 is opened at the bottom of the upper movable mold 30, a core 501 is embedded on the lower pad 50, the core 501 can slide upward through the lower fixed mold 40, and side sliders 402 are symmetrically arranged around the core 501 on the lower fixed mold 40. Specifically, when the mold is closed, the sliders 402 on both sides close and cover the core 501, and the molding column 401 contacts the core 501. The core 501 and the sliders 402 on both sides are used to form the main body of the steam engine boiler shell 80. The inclined guide columns set on the upper movable mold 30 drive the molding column 401 to be close to or leave the core 501. The molding column 401 is used to form the through hole 802 on the side of the steam engine boiler shell 80, that is, to realize the molding of the steam engine boiler shell 80. The design of using the sliders 402 on both sides instead of the fixed mold core makes the mold assembly convenient and improves the production efficiency.

[0036] Reference Figure 2-7As shown, the side slider 402 has a first arc groove 4021 on its end faces facing each other, and a plurality of first forming slits 4024 are formed at the bottom of the first arc groove 4021. The first forming slits 4024 are used to form the ribs 801 arranged from top to bottom on the outer side of the steam engine boiler housing 80. Furthermore, the side slider 402 has an insert 4022 in the first arc groove 4021, and the insert 4022 has a second forming slit 4025 on its end face facing the core 501. Specifically, when the mold is closed, the two inserts 4022 collide with each other to form the handle of the steam engine boiler housing 80, and the second forming slit 4025 is used to form the ribs 801 at the handle.

[0037] A second arc groove is formed on the side of the side slider 402. The two second arc grooves are closed to form a channel for the molding column 401 to move. When the mold is closed or opened, the molding column 401 enters or exits the cavity through the channel formed by the closed second arc grooves.

[0038] Reference Figure 2-7 As shown, extension blocks are extended on both sides of the lower fixed mold 40, and the extension blocks are installed with a cylinder 403, and the piston rod of the cylinder 403 is connected to the side slider 402. Specifically, the cylinder 403 is controlled to drive the side slider 402 to approach or leave the core 501 to achieve mold closing and mold opening. The use of extension blocks with extension design on both sides to install the cylinder 403 can reduce the overall size of the mold and meet the moving distance of the side slider 402. Furthermore, two limit sensors 404 are further installed on the extension block, and the side slider 402 is installed with a sensing rod, and one end of the sensing rod is placed between the two sensors. Specifically, the movement of the side slider 402 drives the sensing rod to move back and forth between the two sensors, which is used to limit the two extreme positions of the side slider 402 when opening and closing the mold, and plays a protective role.

[0039] Reference Figure 2-7 As shown, the upper movable mold 30 is provided with wedge blocks 302 on both sides of the groove 301, and the side slider 402 is provided with a positioning hole. Specifically, when the mold is closed, the upper movable mold 30 is pressed down to drive the wedge blocks 302 to be inserted into the positioning holes to prevent the pressure in the cavity from being too high during injection, pushing the side sliders 402 to separate away from each other, resulting in product scrapping. Furthermore, the upper movable mold 30 is further provided with a top block 303 on one side of the groove 301. When the mold is closed, the upper movable mold 30 is pressed down to drive the inclined surface of the top block 303 to contact the end of the molding column 401 away from the core 501, ensuring that the molding column 401 contacts the core 501, and no burrs are generated around the through hole 802.

[0040] In addition, a plurality of ejector rods are arranged on the ejector plate 60, and the ejector rods can slide upward through the lower pad 50 to connect to the lower fixed mold 40. When the mold is opened, the sliders 402 on both sides are separated, the molding column 401 withdraws from the cavity, and the ejector plate 60 pushes the ejector rods upward to push the lower fixed mold 40, pushing the product off from the core 501, thereby realizing the demoulding of the product.

[0041] The above description is only the preferred implementation of the utility model, and is not intended to limit the utility model. For those skilled in the art, the utility model can have various modifications and changes. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the utility model shall be included in the protection scope of the utility model.
