[0023] The preferred embodiments of the present invention will be described in detail below with reference to the drawings, and the present invention will be further elaborated.

[0024] First, the mold with a secondary mold opening slider according to the embodiment of the present invention will be described in conjunction with Figures 1 to 7 It is used in injection molding equipment and has a wide range of application scenarios.

[0025] As Figures 1 to 7As shown, the mold with a secondary mold opening slider of the embodiment of the utility model comprises: a primary slider 1, a secondary slider 2, a secondary slider seat 3, a primary shovel base 4 and a secondary shovel base 5; the two ends of the primary slider 1 are respectively slidably connected with the two ends of the secondary slider 2 through a first limiting slide rail 61, and the first limiting slide rail 61 is fixedly connected with the secondary slider 2; the middle part of the primary slider 1 is slidably connected with the front end of the primary shovel base 4 through a second limiting slide rail 62, and the second limiting slide rail 62 is fixed to the front end of the primary shovel base 4; the secondary slider seat 3 is slidably connected with the primary shovel base 4, and its front end is fixedly connected with the secondary slider 2; the secondary shovel base 5 penetrates the primary shovel base 4 and is slidably connected with the primary shovel base 4 (the above is the prior art);

[0026] A pair of first limiting grooves 31 are provided on the secondary slider seat 3, and a pair of clamping grooves 41 are provided on the primary shovel base 4. The pair of clamping grooves 41 correspond to the pair of first limiting grooves 31 one by one, and a first limiting step 311 is provided in the first limiting groove 31;

[0027] A key 71 is movably disposed in the first limiting groove 31, a second limiting step 711 is disposed on the key 71, a pair of springs 72 are disposed between the first limiting step 311 and the second limiting step 711, and the spring 72 is used for pressing and resetting the key 71; the first limiting step 311 is used to cooperate with the first limiting step 711 to limit the position of the key 71 and the spring 72;

[0028] A first pressing plate 73 is also disposed in the first limiting groove 31, and the first pressing plate 73 is used to limit the position of the card key 71;

[0029] Both ends of the latch key 71 can protrude out of the first limiting groove 31;

[0030] A collision block 8 is also provided at the lower end of the key 71, and a rising inclined surface 81 is provided on the collision block 8. The lower end of the key 71 is slidably connected to the collision block 8, and the collision block 8 is slidably connected to the secondary slider seat 3 and does not move with the secondary slider seat 3. The collision block 8 is fixedly connected to the rear template.

[0031] Furthermore, the longitudinal section of the latch key 71 is cross-shaped, which prevents the latch key 71 from being separated from the first limiting groove 31 .

[0032] Furthermore, a first inclined surface 712 is disposed at the lower end of the latch key 71 , and the first inclined surface 712 can be fitted with the ascending inclined surface 81 to prevent the secondary slider seat 3 from retreating, thereby preventing the secondary slider 2 from retreating.

[0033] Furthermore, a chamfer is provided at the upper end of the latch key 71 to facilitate the upper end of the latch key 71 to enter the corresponding latching groove 41 .

[0034] Furthermore, the first pressing plate 73 is fixed in the first limiting groove 31 by screws to facilitate disassembly.

[0035] Furthermore, a chamfer is provided at one end of the clamping groove 41 close to the secondary slider seat 3, facilitating the upper end of the clamping key 71 to enter the corresponding clamping groove 41.

[0036] Working principle: Before mold opening, the lower end of the first inclined surface 712 of the lower end of the clamping key 71 fits with the lower end of the rising inclined surface 81 of the striker 8. The upper end of the clamping key 71 does not protrude from the first limiting groove 31, and the spring 72 is in a compressed state. During mold opening, under the action of the secondary lifter base 5, the primary lifter base 4 is driven to move to the right. The primary lifter base 4 drives the primary slider 1 away from the product, and the clamping key 71 has a tendency to move along the rising inclined surface 81. Then, when the right side of the secondary lifter base 5 contacts the secondary slider seat 3, the clamping groove 41 at the lower end of the primary lifter base 4 moves above the clamping key 71. The secondary lifter base 5 drives the primary lifter base 4 and the secondary slider seat 3 to move to the right together. While moving to the right, the clamping key 71 moves upward along the inclined surface, and the upper end of the clamping key 71 enters the clamping groove 41. The secondary lifter base 5 continues to move to the right until the secondary slider 2 is separated from the product. During mold closing, the secondary lifter base 5 drives the secondary slider seat 3 and the primary lifter base 4 to move toward the seat. After the secondary slider 2 is closed, the clamping key 71 disengages from the clamping groove 41 under the elastic force of the spring 72. The secondary lifter base 5 continues to drive the primary lifter base 4 to move to the left until the primary slider 1 is completely closed.

[0037] As above, with reference to Figures 1 to 7 The mold with a secondary mold opening slider according to the embodiment of the present invention is described. The primary slider and the secondary slider are segmented core-pulled by the clamping key, and the actions of the two sliders are kept distinct, greatly reducing the defective rate.
