Three-rod double-slide large-angle inclined jacking core-pulling ejector pin device

Abstract

The invention discloses a three-rod double-slide large-angle inclined jacking core-pulling ejector pin device, which comprises an inclined slide seat (1), an inclined slide foot (2), an inclined ejector pin (3), a parallel guide rod (4), an auxiliary slide block (5) and an auxiliary guide rod (6). According to the three-rod double-slide large-angle inclined jacking core-pulling ejector pin device, the auxiliary slide block is arranged between the inclined slide seat and the inclined slide foot and slides in a sliding chute A of the inclined slide seat, the inclined slide foot slides in a sliding chute B of the auxiliary slide block; the inclined ejector pin is orthogonally and fixedly connected with the inclined slide foot, the parallel guide rod and the inclined ejector pin are parallel and orthogonally slide through the inclined slide foot, and the auxiliary guide rod orthogonally slides through the auxiliary slide block; and when the three-rod double-slide large-angle inclined jacking core-pulling ejector pin device works, the auxiliary slide block is driven to obliquely slide along the sliding chute A of the inclined slide seat by the auxiliary guide rod, the inclined slide foot slides in the sliding chute B of the auxiliary slide block, then, the inclined ejector pin and an inclined core-pulling block are driven to be jacked out and reset. According to the technical scheme, through the driving function of the auxiliary slide block and the auxiliary guide rod, the inclined jacking core-pulling ejector pin device can reach the aims of wear reduction, life prolongation, easiness in resetting, and enlargement in inclined jacking applied angle.

Description

technical field [0001] The invention relates to an inclined top core-pulling ejector device, specifically a three-bar double-sliding large-angle inclined top pumping device for injection molds, which is used to pull out the core block embedded in the inner undercut of the product obliquely through the inclined top. Core ejector device. Background technique [0002] There are two types of inclined top core-pulling ejector devices for injection molds in the prior art: single-rod single-sliding ejector pins and double-rod single-sliding ejector pins. Inclined top core pulling less than 15°; double-rod single-sliding ejector rod, refer to Figure 6 , Figure 7 , which is composed of inclined sliding seat, inclined sliding foot, inclined ejector rod, and parallel guide rod. The double-rod single-sliding ejector rod can be used for inclined top core-pulling with an inclination angle of 10-35°; When the upper limit is 35°, the double-rod single-sliding ejector rod will be stuck d...

Problems solved by technology

[0002] There are two types of inclined top core-pulling ejector devices for injection molds in the prior art: single-rod single-sliding ejector pins and double-rod single-sliding ejector pins. Inclined top core pulling less than 15°; double-rod single-sliding ejector rod, refer to Image 6 , Figure 7 , which is composed of inclined sliding seat, inclined sliding foot, inclined ejector rod, and parallel guide rod. The double-rod single-sliding ejector rod can be used for inclined top core-pulling with an inclination angle of 10-35°; When the upper limit is 35°, the double-rod single-sliding ejector rod will be stuck due to increased wear of the inclined slide seat, resulting in damage to the inclined ejector rod; in addition, the inclined sliding feet cannot be completely reset, resulting in flashing of the product around the inclined core block , resulting in poor product quality; when the inclination angle of the inclined top core of the mold is greater than the upper limit of 35°, the double-rod single-sliding ejector rod will appear self-locking and cannot work

Therefore, the prior art has problems and deficiencies such as short wear life, inability to fully reset, and limited applicable angles.
