Detailed Description
Referring to fig. 1 to 7, the utility model discloses a double-shot injection molding slide block shovel machine die structure, which comprises a front die and a rear die, wherein the rear die 1 is formed by connecting two rear die 1 blocks through a steel plate, so that the production efficiency is higher, and the two rear die 1 blocks can be integrally arranged; the front mould comprises a first front module 2 and a second front module 3, the first front module 2 and the second front module 3 are fixed through a steel plate, the first front module 2 and the second front module 3 can be integrally arranged, a first forming cavity is arranged in the first front module 2, a second forming cavity is arranged in the second front module 3, a sliding block 4 capable of sliding is arranged in the front mould, a first shovel machine 5 is arranged in the first front module 2, a second shovel machine 6 is arranged in the second front module 3, a slant poking plate 7 is arranged on the second shovel machine 6, a poking groove 8 is arranged on the sliding block 4, a limiting block 9 is arranged in the poking groove 8, a reset structure capable of enabling the limiting block 9 to reset is arranged in the poking groove 8, when the mould is closed, the limiting block 9 can be squeezed open by the slant poking plate 7 to enter the poking groove 8, and when the mould is opened, the poking groove 8 can squeeze the limiting block 9 to enable the sliding block 4 to withdraw.
As shown in the figure, the sliding block 4 is provided with a sliding groove 10, the sliding groove 10 is perpendicular to and is communicated with the toggle groove 8, and one end of the limiting block 9 is located in the sliding groove 10. The reset structure comprises a reset spring 11, a limit boss 12 arranged in a sliding groove 10 and a limit lug 13 arranged on a limit block 9, one end of the reset spring 11 is abutted against the sliding groove 10, the other end of the reset spring 11 is abutted against the limit block 9, the limit block 9 can enable the limit lug 13 to be clamped with the limit boss 12 under the pushing of the reset spring 11, through the structure, after the limit block 9 is extruded by the inclined poking plate 7, the limit block 9 can reset through the extrusion of the reset spring 11, and the reset position can be guaranteed to be the same through the limit lug 13 and the limit boss 12. In order to ensure that the return spring 11 cannot be disengaged from the limiting block 9, the limiting block 9 is provided with a spring groove 16, the other end of the return spring is positioned in the spring groove 16, and further, the sliding groove 10 is provided with a baffle 17, so that the limiting block 9 can move in the sliding groove 10 to be prevented from jumping out of the sliding groove 10.
