[0020] The technical solution of this utility model will be further described below with reference to the accompanying drawings and specific embodiments.
[0021] like Figures 1 to 4As shown in this embodiment, a sliding demolding injection mold structure includes a driving cylinder 1, a sliding seat 3, a sliding pin 4, a front mold core 5, and a rear mold core 6. The driving end of the driving cylinder 1 is fixedly connected to the rear end of the sliding seat 3. The sliding seat 3 moves along the front-back direction. The front end of the sliding seat 3 is connected to the sliding pin 4. A product forming position is formed between the front mold core 5 and the rear mold core 6. The sliding pin 4 is inserted into the product forming position. An inclined insert block 8 is provided on the outer side of the rear mold core 6. The inclined insert block 8 is inserted into the rear mold core 6 at an angle.
[0022] The drive cylinder 1 controls the slide seat 3 to move back and forth, inserting the slide pin 4 into the product forming position between the front mold core 5 and the rear mold core 6. In order to prevent the slide seat 3 from moving backward, the upper shovel 2 moves down and locks the slide seat 3 at its limit position. When the front mold core 5 and the rear mold core 6 are forming the outer side of the product 7, the slide pin 4 is responsible for forming the inner side of the product 7. After injection molding, the inclined insert blocks 8 on both sides of the rear mold core 6 are moved outward to free up the side inclined surface similar to the anti-slip mat of the luggage rack. Then the shovel 2 moves up, and the drive cylinder 1 pulls out the slide pin 4 through the slide seat 3. Finally, the front mold core 5 and the rear mold core 6 can be separated and the product 7 can be demolded.
[0023] A sliding base pad 9 is provided between the drive cylinder 1 and the rear mold core. The fixed end of the drive cylinder 1 is fixed on the sliding base pad 9. A cylinder mounting block 10 is fixed on the sliding base pad 9. The cylinder mounting block 10 and the sliding base pad 9 are connected by screws. A guide groove 11 is provided on the cylinder mounting block 10. The drive end of the drive cylinder 1 passes through the guide groove 11. The drive cylinder 1 is mounted on the cylinder mounting block 10. The extension and retraction of the drive end is restricted by the guide groove 11. Under the fixing action of the sliding base pad 9, the entire sliding demolding injection mold structure can be installed on the mold for use.
[0024] A shovel 2 is provided above the slide seat 3. A first inclined surface is provided on one side of the shovel 2. A second inclined surface 12 is provided at the rear end of the slide seat 3. The first inclined surface and the second inclined surface 12 are in sliding contact. A slide wear-resistant block 13 is fixed on the second inclined surface 12 with screws. The slide seat 3 is slidably connected to the slide wear-resistant block 13. The shovel 2 moves from top to bottom. On the first inclined surface, the slide wear-resistant block on the second inclined surface 12 is tilted and rubbed, which restricts the slide seat 3 from moving backward and makes the product 7 in the front mold core 5 and the rear mold core 6 more stable.
[0025] The middle part of the slide pin 4 is provided with a first cooling water channel 14, and the interior of the slide seat 3 is provided with a second cooling water channel 15 that communicates with the outside. The first cooling water channel 14 and the second cooling water channel 15 are connected. A waterproof ring 16 is provided between the first cooling water channel 14 and the second cooling water channel 15. The waterproof ring 16 is fixed on the slide seat 3. External cooling water is injected from the second cooling water channel 15 of the slide seat 3. After being waterproofed by the waterproof ring 16, it enters the first cooling water channel 14 to cool the slide pin 4, so as to better inject the next product 7.
[0026] It should be stated that the above-described specific embodiments are merely preferred embodiments of this utility model and the technical principles applied thereto. Within the scope of the technology disclosed in this utility model, any variations or substitutions that are easily conceived by those skilled in the art should be covered within the protection scope of this utility model.
