[0002] In the field of plastic mold making, especially for the production of products with large angles and multiple snap-fit ​​joints, the large snap-fit ​​angles and limited space lead to complex ejection processes and a high risk of deformation. Existing mold structures are typically complex, occupy a large amount of space, have high manufacturing costs, and long production cycles. In actual production, unreasonable angled ejector designs often result in uneven ejection, leading to ejector breakage and disrupting normal production. Furthermore, problems such as mold sticking, excessive ejection height, and malfunctioning movements are common, requiring frequent mold repairs, wasting significant time, and reducing production efficiency. Utility Model Content

[0003] The purpose of this utility model is to provide a large-angle downward inclined ejector structure for plastic molds. Through the guide rod, the movable seat is guided to make the inclined ejector block and the movable seat eject synchronously. After moving a certain distance, the inclined ejector block disengages from the product, thereby meeting the demolding and structural requirements of such products.

[0004] To achieve the above objectives, the following technical solution is adopted:

[0020] The present invention will be described in detail below with reference to the accompanying drawings and specific embodiments.

[0021] Reference Figures 1 to 5 As shown, this utility model provides a large-angle downward inclined top structure for a plastic mold, including a base plate 1, a lifting plate 2 arranged above the base plate 1, and a mold base 3 arranged above the lifting plate 2. In one embodiment, a support rod 4 is fixedly connected between the base plate 1 and the mold base 3, and the support rod 4 is inclined towards one end of the mold base 3; a first mounting hole 21 is provided on the lifting plate 2, and a first fixing block 22 is fixedly installed on each of the two inner walls of the first mounting hole 21; a first guide groove 23 is also provided on the opposite side of each of the two first fixing blocks 22, and the first guide groove 23 is inclined towards the other side of the mold base 3. One end is inclined upward; a movable block 24 is also movably arranged between the two first fixed blocks 22, and the outer walls on both sides of the movable block 24 are provided with guide protrusions 25 that are adapted to the first guide groove 23 at the corresponding positions; the guide protrusions 25 are movably inserted into the first guide groove 23; the support rod 4 is movably arranged through the movable block 24; a slanted push rod 26 is also installed on the movable block 24, the slanted push rod 26 is arranged parallel to the support rod 4, and the upper part of the slanted push rod 26 movably passes through the mold base 3 and extends upward; the top of the slanted push rod 26 is also connected to a slanted push block 27.

[0022] Reference Figure 5As shown, the product targeted by this utility model has a fan-like structure. The bottom of the fan blades has several fasteners (the fasteners together form a fan-shaped structure). The top of the inclined top block 27 has an inclined surface, and a locking block 28 is provided on the inclined surface. The inclined surface is a contoured structure of the bottom plane of the fan blades, which can fit tightly against the bottom surface of the fan blades. The locking block 28 on the inclined surface matches the fasteners and is locked within the fasteners. Due to the large angle of the fasteners and the lack of space in the middle, the structure is complex. Using a conventional inclined top structure often results in problems such as mold sticking, excessive ejection, and uneven movement, leading to frequent maintenance of the lower mold, wasting time, and affecting production efficiency. Therefore, a large-angle downward inclined top structure is designed. Preferably, the downward angle is 45°, that is, the inclination angle of the first guide groove 23 is 45°, meaning the movable block 24 can pass through the guide protrusion 25 (guide... The protrusion 25 is adapted to the first guide groove 23 (also with a 45° inclined structure) and moves along the first guide groove 23. When ejecting the product, the lifting plate 2, under the action of external force, drives the first fixed block 22, the movable block 24, and the inclined ejector rod 26 to rise synchronously along the support rod 4, so that the inclined ejector block 27 is pushed to the bottom of the product to apply lifting force to eject the product. During the ejection process, the support rod 4 will generate a downward squeezing force on the movable block 24, so that the movable block 24 moves down along the first guide groove 23 through the guide protrusion 25, thereby causing the locking block 28 on the inclined ejector block 27 to disengage, thus meeting the demolding and structural requirements of this type of product. Through the structural design of the guide rod 4 and synchronous movement, this utility model can effectively avoid the situation of uneven ejection of the inclined ejector and breakage due to unbalanced force, ensuring smooth product demolding and improving production stability.

[0023] Preferably, in this embodiment, a second fixing block 11 is installed on the base plate 1, a third fixing block 31 is installed on the mold base 3, and a support rod 4 is connected between the second fixing block 11 and the third fixing block 31; the support rod 4 is arranged to move through one end of the movable block 24; the inclined push rod 26 is installed at the other end of the movable block 24, and the upper part of the inclined push rod 26 moves through the third fixing block 31 and the mold base 3 in sequence; a first fixing hole is opened at the bottom of the inclined push block 27, and a second fixing hole is opened on one side of the inclined push block 27, which extends into the first fixing hole; the upper part of the inclined push rod 26 passes through the mold base 3 and is inserted into the first fixing hole, and a first latch 261 is also opened on the outer wall of the inclined push rod 26 corresponding to the second fixing hole; a locking block 262 is also installed in the second fixing hole, and the middle part of one side of the locking block 262 is locked in the first latch 261; a locking hole for installing screws is also opened on the locking block 262. The second fixing hole and the locking hole have corresponding holes, and screws can be installed in the locking hole to lock and fix the inclined top block 27 and the inclined top rod 26 to ensure the stability of the connection between the two.
