Detailed Description

The present invention will be described in further detail with reference to the accompanying drawings and specific embodiments.

Referring to fig. 1 to 12 (since the mold is multipurpose, that is, two products are produced, a schematic diagram of two products appears in fig. 12), a double-color mold for secondary rubber coating of a refueling wicket actuator comprises a first mold 1 and a second mold 2, the first mold 1 comprises a first upper mold plate 3 and a first lower mold plate 4, the second mold 2 comprises a second upper mold plate 5 and a second lower mold plate 6, a first cavity 7 is arranged in the first upper mold plate 3, a first core 8 is arranged in the first lower mold plate 4, a second cavity 9 is arranged in the second upper mold plate 5, a second core 10 is arranged in the second lower mold plate 6, a movable cavity 11 is arranged in the first lower mold plate 4, a locking block 12, a sliding block 13 and an insert 14 are arranged in the movable cavity 11, the locking block 12 is connected with the first upper mold plate 3, the upper end of the insert 14 is connected with a first core 8, the locking block 12 is provided with a first inclined surface 15, the sliding block 13 is provided with a second inclined surface 16 and a third inclined surface 17, the lower end of the insert 14 is provided with a fourth inclined surface 18, the first inclined surface 15 abuts against the second inclined surface 16, and the third inclined surface 17 abuts against the fourth inclined surface 18. The first mold is internally provided with a first encapsulation structure, the first encapsulation structure is the same as the working process of the existing common injection molding machine, a slide block 13 and an insert 14 are locked through a locking block 12, the insert 14 is positioned at the uppermost end, when the second encapsulation is carried out, a first upper template 3 is separated from a first lower template 4, the first lower template 4 and a second lower template 6 simultaneously rotate 180 degrees to carry out position exchange, the locking block 12 is separated from the slide block 13 along with the separation of the first upper template, at the moment, the insert 14 moves downwards, the slide block 13 slides leftwards, and the insert 14 drives a first core to move downwards, so that a second mold core for the second encapsulation is formed by the insert 14 and a second cavity 9 in a second upper template 5.

In this embodiment, a spring 19 is disposed in the slide 13, and the other end of the spring 19 is connected to the first lower mold plate 4. The spring 19 limits the slide block 13 from sliding freely under the action of the spring 19 when the second encapsulation is carried out, and the slide block 13 is prevented from moving excessively to be separated from the insert 14.

In this embodiment, the insert 14 is provided with a thimble 20 for resetting. During the second encapsulation, in order to ensure that the insert 14 moves downwards to return to the position of the second encapsulation, an ejector pin 20 is arranged on the insert 14, and during the first encapsulation, the ejector pin is slightly higher than the upper end of the first lower template 4, and a through hole matched with the ejector pin is arranged on the first upper template 3, so that the ejector pin 20 cannot be abutted, during the second encapsulation, the second upper template 5 has no through hole, so that during mold closing, the second upper template 5 presses the ejector pin 20 downwards, so that the ejector pin 20 moves downwards (the moving distance is the size that the ejector pin is higher than the first lower template 4) to be flush with the first lower template 4, so as to realize the return, and when the mold continues to work, the first lower template 4 continues to rotate 180 degrees, at this time, during demolding from the second upper template 5, the spring 19 moves the slider 13 to the rightmost end through the self elasticity, and drives the insert 14 and the first core 8 to move upwards to the highest end (namely, the position of the first encapsulation), at this time, the thimble on the insert pushes the first lower template 4 upwards and is matched with the via hole in the first upper template 3.

In this embodiment, a sliding groove 21 adapted to the locking block 12 is provided in the sliding block 13. The locking block 12 is in the slide slot 21 and limits the movement of the slide 13, thus ensuring the stability of the insert 14 during the first encapsulation.

In this embodiment, the first lower template 4 and the second lower template 6 have the same structure. In order to ensure the continuous operation of the double-color mold, the structures of the first lower template 4 and the second lower template 6 are set to be completely consistent, so that continuous first and second rubber coating can be carried out by rotating 180 degrees, and the production efficiency is greatly improved.

In this embodiment, the concentricity of the first lower template and the first upper template, the concentricity of the first lower template and the second upper template, the concentricity of the second lower template and the first upper template, and the concentricity of the second lower template and the second upper template are all within 0.005 mm. Because the two times of encapsulation are combined with different upper templates, in order to ensure that the product has no step difference, the concentricity of the upper template and the lower template must be within 0.005 mm.

The utility model has the advantages that: through the secondary rubber coating double-color die, the full-automatic secondary rubber coating of the oil filling small door actuator can be realized, manual operation or separate rubber coating is not needed, the production efficiency is greatly improved, and the product quality is ensured.

This embodiment is only one of the preferable embodiments of this patent, and any changes made without departing from the scope of this patent are within the scope of this patent.
