[0020] The following are specific embodiments of the present invention and the accompanying drawings to further describe the technical solution of the present invention, but the present invention is not limited to these embodiments.

[0021] A slider linkage core pulling structure, such as Figures 1 to 5 As shown, it includes a main core-pulling slider 1 and an auxiliary core-pulling slider 2. It should be noted that the driving mechanism of the main core-pulling slider 1 belongs to the prior art and will not be described in detail.

[0022] The main core-pulling slider 1 is slidably set on the base 3. Specifically, a slide groove 11 is opened on the main core-pulling slider 1, and the slide groove 11 is opened in the horizontal direction. The auxiliary core-pulling slider 2 is slidably set in the slide groove 11. The slide of the auxiliary core-pulling slider 2 is guided by the slide groove 11, so that the auxiliary core-pulling slider 2 can slide more smoothly. It should be noted that the driving mechanism for driving the auxiliary core-pulling slider 2 belongs to the existing technology and will not be described in detail.

[0023] The auxiliary core-pulling slider 2 is slidably arranged on the main core-pulling slider 1, and the auxiliary core-pulling slider 2 is connected to the core-pulling inclined block 4. The auxiliary core-pulling slider 2 and the core-pulling inclined block 4 are connected by bolts 14, so as to ensure that the connection between the auxiliary core-pulling slider 2 and the core-pulling inclined block 4 is stable and reliable, and it is convenient to disassemble and maintain the two.

[0024] At least two slide grooves 2 12 are provided on the main core-pulling slider 1. The two slide grooves 2 12 are both provided in the horizontal direction. The two slide grooves 2 12 are arranged opposite to each other. The length direction of the slide groove 1 11 is the same as that of the slide groove 2 12. The two sides of the core-pulling inclined block 4 are respectively slidably arranged in the two slide grooves 2 12. The sliding of the core-pulling inclined block 4 is guided by the slide groove 2 12, so that the core-pulling inclined block 4 is more stable when sliding.

[0025] The insert 6 is used to form a concave structure on the lower surface of the product. The end of the main core-pulling slider 1, the end of the core-pulling inclined block 4 and the end of the insert 6 are all adapted to the outer surface of the product.

[0026] The upper surface of the core pulling inclined block 4 is provided with a supporting inclined surface 5. It should be noted that the supporting inclined surface 5 is inclined from bottom to top from one end close to the product to the end away from the product. An insert 6 is slidably provided on the supporting inclined surface 5. The core pulling inclined block 4 is used to support the insert 6, and the lower surface of the insert 6 is in contact with the supporting inclined surface 5.

[0027] Specifically, a T-shaped portion 7 is obliquely provided on the support inclined surface 5 , a T-shaped slot 8 is obliquely provided on the insert 6 , the T-shaped portion 7 is adapted to the T-shaped slot 8 , the T-shaped portion 7 is inserted into the T-shaped slot 8 , and the two are slidably matched.

[0028] At least two linkage guide blocks 9 are provided at the end of the insert 6, and at least two linkage guide grooves 10 are opened on the main core-pulling slider 1. The two linkage guide blocks 9 are respectively slidably matched with the two linkage guide grooves 10. The two linkage guide blocks 9 are slidably set in the two linkage guide grooves 10. The two linkage guide grooves 10 limit the two linkage guide blocks 9 respectively. The two linkage guide grooves 10 are both opened in the vertical direction. Through the cooperation between the two linkage guide grooves 10 and the two linkage guide blocks 9, the insert 6 is guided so that the insert 6 can only slide along the linkage guide grooves 10, that is, the insert 6 can only slide in the vertical direction.

[0029] The auxiliary core-pulling slider 2 drives the core-pulling inclined block 4 away from the product by sliding, so that the insert 6 is separated from the recessed structure of the product. It should be noted that when the auxiliary core-pulling slider 2 drives the supporting inclined surface 5 away from the product by sliding, through the cooperation of the T-shaped portion 7 and the T-slot 8 and the restriction of the linkage guide groove 10 on the linkage guide block 9, the insert 6 slides downward along the linkage guide groove 10 under the drive of the core-pulling inclined block 4, thereby separating the insert 6 from the recessed structure of the product. It should be further noted that due to the gravity of the insert 6 itself, the insert 6 can be further helped to slide downward along the linkage guide groove 10 to separate from the recessed structure of the product, thereby ensuring that the insert 6 can smoothly separate from the recessed structure of the product. Since the insert 6 separates from the recessed structure of the product without the need for an additional driving mechanism for its separation direction, the production cost and complexity of the mold can be reduced, and the space occupied by the mold can be reduced.

[0030] The main core-pulling slider 1 slides away from the product, and the main core-pulling slider 1 drives the insert 6, the auxiliary core-pulling slider 2 and the core-pulling bevel block 4 away from the product. It should be noted that since the two linkage guide blocks 9 are slidably arranged in the two linkage guide grooves 10, the two linkage guide grooves 10 respectively limit the two linkage guide blocks 9. Therefore, when the main core-pulling slider 1 slides, the insert 6 can be driven to move, and the auxiliary core-pulling slider 2 is slidably arranged in the slide groove 11 of the main core-pulling slider 1, and the core-pulling bevel block 4 is connected to the auxiliary core-pulling slider 2. Therefore, when the main core-pulling slider 1 slides, the auxiliary core-pulling slider 2 and the core-pulling bevel block 4 can be driven to move.

[0031] An avoidance hole 13 is provided on the main core-pulling slide block 1 , and the core-pulling inclined block 4 is passed through the avoidance hole 13 , so that the travel of the core-pulling inclined block 4 is avoided through the avoidance hole 13 .

[0032] The working principle of the utility model is as follows:

[0033] When pulling the core, the auxiliary core-pulling slider 2 drives the core-pulling inclined block 4 away from the product by sliding. The core-pulling inclined block 4 drives the insert 6 to slide downward along the linkage guide groove 10 through the cooperation between the T-shaped portion 7 and the T-shaped groove 8 and the restriction of the linkage guide groove 10 on the linkage guide block 9, so that the insert 6 is separated from the recessed structure of the product, and then the main core-pulling slider 1 slides away from the product, and the main core-pulling slider 1 drives the insert 6, the auxiliary core-pulling slider 2 and the core-pulling inclined block 4 away from the product.

[0034] The specific embodiments described in this article are merely examples of the spirit of the utility model; technicians in the technical field to which the utility model belongs can make various modifications or additions to the described specific embodiments or replace them in a similar manner, but will not deviate from the spirit of the utility model or exceed the scope defined by the attached claims.
