Detailed Description

In order that the present invention may be more readily and clearly understood, the following detailed description of the present invention is provided in connection with the accompanying drawings.

In the present embodiment, as shown in fig. 1-7, a new slider structure for preventing the falling of the product is provided, which is separately installed on the moving and fixed mold and mainly consists of a T-shaped slider 1, a guide rail 2 and two inclined guide blocks 3. Wherein guide rail 2 fixed mounting is in cover half 6 rear end, and the T spout 20 of fore-and-aft direction is seted up to one side that cover half 6 was kept away from to guide rail 2, and T slider 1 slip joint is in the T spout 20 of guide rail 2. The two inclined guide blocks 3 are asymmetrically arranged at the front end and the rear end of the movable die 7, and the two inclined guide blocks 3 are asymmetrical so as to drive the T-shaped slide block 1 to slide towards different directions during twice die assembly.

In order to realize that the inclined guide block 3 can drive the T-shaped slide block 1 to slide back and forth during die assembly, a V-shaped groove 100 is formed in one side, away from the guide rail 2, of the T-shaped slide block 1, the V-shaped groove 100 penetrates through the T-shaped slide block up and down and is provided with a front inclined plane and a rear inclined plane; meanwhile, one side of the inclined guide block 3 close to the T-shaped sliding block 1 is formed into a V-shaped inclined plane 30 matched with the V-shaped groove 100, and the V-shaped inclined plane 30 is also provided with a front inclined plane and a rear inclined plane; of course, the angles of the V-shaped groove 100 and the V-shaped inclined surface 30 must ensure that both the two inclined guide blocks 3 after the mold rotates can be pressed into the V-shaped groove 100, and the installation positions of the two inclined guide blocks 3 on the movable mold 7 also ensure that the T-shaped slide block 1 can be pushed to move forward and backward when being pressed into the V-shaped groove 100. In addition, a stopper 10 is formed at the front end of the T-shaped slider 1, and the stopper 10 is used for pressing and blocking a color product to prevent the falling of the product when the mold rotates.

In the present embodiment, a case where the movable mold 7 is rotated by 180 degrees at the time of two-color injection is taken as an example. Referring to the state illustration of fig. 6, when the mold is closed for the first time, the movable mold 7 may drive the two inclined guide blocks 3 to approach the fixed mold 6, the V-shaped inclined surface 30 of one of the inclined guide blocks 3 can be just pressed into the V-shaped groove 100 of the T-shaped slider 1, the front inclined surface (the upper inclined surface in fig. 6) of the V-shaped inclined surface 30 of the inclined guide block 3 slides and pushes against the front inclined surface (the upper inclined surface in fig. 6) of the V-shaped groove 100 of the T-shaped slider 1, so as to push the T-shaped slider 1 to move forward (the upward direction in fig. 6) to push the stopper 10 forward, and the stopper 10 is in the forward pushing state after the first mold closing, so as to form a pressing stopper for an end of a color product, thereby preventing the product from dropping. Then the movable die 7 is far away from the fixed die 6 to perform die opening for the first time, then the movable die 7 rotates 180 degrees, so that the other inclined guide block 3 is just aligned to the T-shaped slide block 1, and then die closing is performed for the second time. Referring to the state illustration of fig. 7, when the mold is closed for the second time, the movable mold 7 drives the two inclined guide blocks 3 to approach the fixed mold 6, the V-shaped inclined surface 30 of the other inclined guide block 3 can be just pressed into the V-shaped groove 100 of the T-shaped slider 1, the rear inclined surface (the lower inclined surface in fig. 7) of the V-shaped inclined surface 30 of the inclined guide block 3 slides and pushes against the rear inclined surface (the lower inclined surface in fig. 7) of the V-shaped groove 100 of the T-shaped slider 1, and then the T-shaped slider 1 is pushed to move backwards (the downward inclined surface in fig. 7) to retreat the stopper 10, and the stopper 10 is in a retreated state after the second mold closing, that is, the stopper pressing limitation on the injection molded product is cancelled, so that the direct taking of subsequent bicolor products is facilitated, the increase of redundant steps and time is avoided, and the production efficiency is further improved. Of course, the above structural design is also applicable to the case that the fixed mold 6 rotates 180 degrees during the double-color injection molding, and the principle and process are similar to those described above, and redundant description is not provided herein.

In order to give the rear end limit of T shape slider 1, this embodiment still includes stopper 5, and stopper 5 is installed in 6 rear ends of cover half and is located the guide rail 2 rear side, and stopper 5 can restrict the maximum stroke position in rear end of T shape slider 1, prevents that it from sliding and droing.

In order to ensure the stability of the T-shaped sliding block 1 during injection molding and rotation, unnecessary sliding and shaking are prevented. In the embodiment, a mounting hole 21 is formed in an end surface of the T-shaped chute 20 close to the fixed mold 6, an elastic limiting member 4 is arranged in the mounting hole 21, and the elastic limiting member 4 can limit the T-shaped slider 1 in the twice mold closing state.

Specifically, the elastic limiting member 4 in this embodiment is composed of a guiding post 40, a limiting protruding rib 41 and a spring 42, the guiding post 40 is slidably connected in the mounting hole 21, the limiting protruding rib 41 is formed at one end of the guiding post 40 close to the T-shaped slider 1, and the spring 42 is disposed in the mounting hole 21 for extending and contracting the guiding post 40. Meanwhile, two limiting grooves 101 matched with the limiting convex ridges 41 are further formed in one end face, close to the guide rail 2, of the T-shaped sliding block 1, and the two limiting grooves 101 are arranged in a front-back mode. In addition, in order to ensure that the T-shaped sliding block 1 can smoothly slide back and forth without being interfered by limiting, the cross sections of the limiting convex ridges 41 and the limiting grooves 101 are designed into triangular shapes. With such an arrangement, after the mold is closed for the first time, the limiting protruding rib 41 can be clamped into the limiting groove 101 at the back (the lower limiting groove 101 in fig. 6) under the elastic force of the spring 42; after the mold is closed for the second time, the stopper rib 41 can be engaged in the forward stopper groove 101 (the upper stopper groove 101 in fig. 7) by the elastic force of the spring 42. So can make under twice compound die state all can form spacingly to T shape slider 1, and then guarantee its stability, prevent that unnecessary slip from rocking.
