[0018] In order to make the purpose, technical solution and advantages of the utility model clearer, the utility model is further described in detail below in combination with specific implementation methods and with reference to the accompanying drawings. It should be noted that the embodiments of the utility model and the features in the embodiments can be combined with each other without conflict.

[0019] The following describes a mold structure of a protective cover for a central controller of an automobile provided by some embodiments of the utility model in conjunction with the accompanying drawings.

[0020] Example:

[0021] Combination Figure 1-3As shown, the utility model provides a mold structure of a central controller protection cover of an automobile, comprising a front mold core 1, a rear mold core 6 buckled with the front mold core 1, a tilted ejector rod 8 inserted in the middle of the rear mold core 6, a tilted ejector head 7 connected to the top of the tilted ejector rod 8, four movable inserts 2, four movable inserts 2 are evenly arranged on both sides of the tilted ejector head 7, a movable insert 2 is inserted at the position where the tilted ejector rod 8 is installed in the middle of the rear mold core 6, and a slider 3 3 and a slider 2 4 are slidably connected on both sides of the rear mold core 6, and the outer sides of the slider 3 3 and the slider 2 4 are connected It is connected to an oil cylinder 5, and slider three 3 and slider two 4 are symmetrically arranged on both sides of the rear mold core 6. Water transport holes are opened on the front mold core 1, slider three 3, slider two 4, rear mold core 6 and inclined ejector head 7, and the multiple water transport holes are interconnected. Slider one 9 is installed on the side of the rear mold core 6, and a dome needle 10 is installed at the bottom of the rear mold core 6. The bottom end of the inclined ejector rod 8 is connected with an inlet and outlet water pipe, and the inlet and outlet water pipes are connected with the water transport holes. The bottom end of the inclined ejector rod 8 passes through the bottom of the rear mold core 6, and the inlet and outlet water pipes at the bottom of the inclined ejector rod 8 do not contact the rear mold core 6.

[0022] Specifically, by connecting the water inlet and outlet pipes at the bottom of the inclined ejector rod 8 with the water transport hole, cooling water can be introduced into the inclined ejector rod 8, so that the inside and outside cooperate to achieve rapid cooling and shaping, which reduces the shaping time of the product, thereby reducing the overall time of injection molding production and improving efficiency. At the same time, the movable insert 2 is separated from the rear mold core 6 synchronously with the product to avoid product cracking caused by one-time separation, which affects the yield rate. Separating the product from the mold in two steps can avoid this situation to a great extent and improve the yield rate of the device.

[0023] The working principle and use process of the utility model are as follows: first, the front mold core 1 is separated from the rear mold core 6, and the slider 1 9 is slid outward to separate it from the product, and then the slider 3 3 and the slider 2 4 are controlled by the cylinder 5 to slide outward to separate them from the product. At this time, most of the structure has been separated from the product, and the dome needle 10 and the inclined ejector rod 8 are started to push upward, so that the inclined ejector head 7 is disengaged from the buckle position, thereby separating the movable insert 2 from the rear mold core 6, driving the product to separate from the rear mold core 6, completing the first step of demolding, and then removing the movable insert 2 from the product to obtain a complete product. Finally, the structures are assembled back in sequence for the next injection molding.

[0024] Although the embodiments of the present invention have been shown and described, those skilled in the art will appreciate that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and purpose of the present invention, and that the scope of the present invention is defined by the claims and their equivalents.
