Drawings

Fig. 1 is a schematic structural diagram of an embodiment of the present invention.

Detailed Description

The following description will explain embodiments of the present invention with reference to the drawings. As shown in fig. 1: a mould with a fixed mould inclined top comprises a fixed mould part and a movable mould part, wherein the fixed mould part comprises a fixed mould taking plate 1, a stripper plate 2 and a fixed mould plate 3 are sequentially connected below the fixed mould taking plate 1, the movable mould part comprises a movable mould taking plate 4, a movable mould plate 5 is connected above the movable mould taking plate 4, a fixed mould core 6 is arranged in the fixed mould plate 3, a movable mould core 7 is arranged in the movable mould plate 5, when the fixed mould part and the movable mould part are in a mould closing state, the fixed mould core 6 and the movable mould core 7 jointly form a mould cavity, a runner 8 which always runs through to the fixed mould core 6 is arranged in the fixed mould taking plate 1,

The utility model discloses take the working process of the mould of cover half top to one side as follows: under the action of a forming machine, the fixed die part and the movable die part are matched, the fixed die core 6 and the movable die core 7 are enclosed together to form a cavity, the first core-pulling core at the end part of the slide block 12 and the second core-pulling core at the bottom end of the inclined ejector rod 17 are also positioned in the cavity, the forming machine injects a material in a molten state into the cavity through the runner 8, the material is cooled for a period of time after filling the cavity and then solidified to form a required workpiece 24, and an inverted buckle structure is formed on the workpiece 24 at the first core-pulling core and the second core-pulling core;

when the mold is opened, under the action of a compression spring in the pull rod assembly 22, the stripper plate 2 and the fixed mold plate 3 are firstly separated, and the mold opening distance is limited by the length of a limiting pull rod in the spring; at this time, the side draw pin 10 fixedly arranged on the fixed mold unloading plate 1 moves upwards, and the inclined top part 11 at the bottom of the side draw pin 10 is connected in an inclined sliding groove in the slide block 12 in a sliding manner, so that the longitudinal movement of the side draw pin 10 is converted into the horizontal movement of the slide block 12, and the first core-pulling core is laterally drawn out from the cavity to complete the side core-pulling action at the position; at the same time of the above actions, the material handle in the flow channel 8 is separated from the workpiece 24 and retreats along with the fixed die plate 3;

when the die sinking distance between the fixed die plate 3 and the stripper plate 2 reaches a set value, the fixed die plate and the stripper plate are relatively static, the movable die part continues to retreat, and the fixed side die plate above the fixed die plate 3 is limited by the corresponding limit connecting rod and can not move, so that the movable die nylon pin assembly 23 is separated from the movable die plate 5, and the die sinking action between the fixed die plate 3 and the movable die plate 5 is realized;

after the mold is opened, a workpiece 24 is left on one side of the fixed mold part, when a top rod plate pull rod 20 connected to a top rod plate 16 of the fixed mold reaches a set position, the top rod plate 16 of the fixed mold is pulled to move, at the moment, inclined top rods 17 which are distributed in an inclined mode move downwards along with the inclined top plate 16 of the fixed mold and horizontally move relative to the workpiece 24, at the moment, a second core-pulling core is pulled out from a back-off position on the workpiece 24, and the side core-pulling action at the position is completed; the inclined ejector rod 17 is matched with the straight ejector rod 19, and the workpiece 24 is ejected out of the fixed die core 6 by the inclined ejector rod and the straight ejector rod together, so that the workpiece 24 is smoothly demoulded;

in the actual design, the appearance surface of the workpiece 24 is positioned on the side of the movable mold part, the gate generated when the material handle is disconnected is positioned on the side of the non-appearance surface of the workpiece 24, and the ejection mechanism also acts on the side of the non-appearance surface of the workpiece 24, so that the appearance quality of the appearance surface of the workpiece 24 can be ensured.
