Detailed Description

Example one

A mold structure for changing a core pulling angle comprises a large inclined top 3 for pulling a core of a cavity, the large inclined top 3 is arranged on a push plate 12, a slide block 2 for pulling the core of the cavity is further arranged on the large inclined top 3 in a sliding mode, an inclined top slide seat 11 is fixed on the push plate 12, a slide rail is arranged on the inclined top slide seat 11 and is consistent with the inclination direction of the slide block 2, a slide block 14 is arranged on the slide rail in a sliding mode, an inclined top guide rod 8 connected with the large inclined top 3 is fixed on the slide block 14, the inclined top guide rod 8 is vertically arranged on the slide block 14, the slide block 2 is obliquely arranged on the large inclined top 3, the large inclined top 3 drives the slide block 2 to move, a guide groove 7 is formed in the slide block 2, a guide rod 4 is arranged in the guide groove 7 in a sliding mode, and the other end of the guide rod 4 is fixed on a male mold 5 through a cover plate, and an oil cylinder 9 for driving the push plate 12 to move up and down is also fixed on the male die 5.

In order to improve the motion stability of sliding, a T-shaped sliding groove 15 is formed in the large inclined top 3, the sliding block 2 is a T-shaped sliding block 2, and the T-shaped sliding block 2 is arranged in the T-shaped sliding groove 15 in a sliding mode. The included angle between the core-pulling direction of the slide block 2 and the die assembly direction of the die is 70 degrees.

A U-shaped mounting groove 13 is further formed in one side of the sliding block 14, a protection rod 10 is arranged in the mounting groove 13 in a sliding mode, one end of the protection rod 10 is fixedly arranged on the male die 5, the other end of the protection rod is fixedly arranged on the bottom plate 16, and the protection rod 10 is parallel to the inclined ejection guide rod 8. The shape of mounting groove 13 is U-shaped open form, and protection rod 10 is close to the setting of oblique top guide bar 8, and protection rod 10 does not contact with oblique top guide bar 8, because the length that oblique top guide bar 8 set up is longer, for the length that improves oblique top guide bar 8, prevents to push up guide bar 8 at the in-process that pushes out to reset to one side and takes place to warp.

The working principle is as follows: the mold injection molding, pressure maintaining and mold opening are carried out, a piston rod of an oil cylinder 9 is reset, the oil cylinder 9 drives a push plate 12 to eject upwards, in the process that the push plate 12 ejects upwards, the push plate 12 drives an inclined top slide seat 11 to move upwards, a slide rail which inclines towards the slide block 2 is arranged on the inclined top slide seat 11, the inclined top guide rod 8 is arranged on the slide rail in a sliding mode through a slide block 14 at the bottom end, the inclined top slide seat 11 drives an inclined top guide rod 8 to move, the inclined top guide rod 8 drives a large inclined top 3 to move upwards in an inclined mode, namely to move leftwards and upwards in the attached drawing 2, the large inclined top 3 extrudes the slide block 2 to enable the slide block 2 to move downwards in an inclined mode, and due to the guide rod 4 which is arranged in a guide groove 7 of the slide block 2 in a sliding mode, the guide rod 4 limits the moving direction of the slide block 2, so that the slide block 2 forms a 70-, then, the other inner sides in the die are obliquely ejected, the core-pulling slide block 2 and the like are matched to complete core pulling of the product 1, and finally the product 1 is ejected out through straight ejection.
