Abstract
Description
Technical Field
[0001] The invention belongs to the technical field of injection molding machines, and in particular relates to an injection molding machine with a blanking buffer device. Background Art
[0002] An injection molding machine is a device that injects melted plastic into a molding mold to form plastic products of various shapes in the molding mold.
[0003] During the operation of an injection molding machine, after forming, a plastic product is ejected from the mold and falls onto the base of the injection molding machine under the action of gravity. The plastic product is then manually removed. When the plastic product falls onto the base of the injection molding machine, it is subjected to a large impact force, which can easily damage and deform the plastic product, especially if the plastic product has low strength and toughness. Although dedicated industrial robots and manipulators are currently available to remove molded plastic products from the mold, their high cost increases the production cost of plastic products.

DETAILED DESCRIPTION
[0015] In order to further understand the content, features and effects of the present invention, the following embodiments are given as examples and described in detail with reference to the accompanying drawings.
[0016] Please also refer to Figures 1 to 6 The following will describe in detail an injection molding machine with a blanking buffer device according to an embodiment of the present invention with reference to the accompanying drawings.
[0017] The injection molding machine with a blanking buffer device includes a base 1, a clamping mechanism 2, a movable template 3, an auxiliary falling plate 4, and a buffer assembly 5. The clamping mechanism 2 is fixed to the upper end of the base 1, and the movable template 3 is fixed to one end of the clamping mechanism 2. The clamping mechanism 2 drives the movable template 3 to move. A through groove 6 is opened inside the base 1 at a position relative to the clamping mechanism 2. The upper end of the through groove 6 is hingedly connected to the auxiliary falling plate 4. The bottom of the auxiliary falling plate 4 is connected to the buffer assembly 5, and the buffer assembly 5 is fixed to the top of the through groove 6.
[0018] Specifically, a groove 7 is provided on the auxiliary falling plate 4 , and the groove 7 is communicated with the buffer assembly 5 at the bottom.
[0019] Specifically, the auxiliary falling plate 4 is also hingedly connected to a wedge block 8, the hinge point of the wedge block 8 is close to the hinge point end of the auxiliary falling plate 4, and a torsion spring 9 is fixed to the wedge block 8 near the hinge point end, and the torsion spring 9 is fixed to the auxiliary falling plate 4 away from the end of the wedge block 8.
[0020] Specifically, the buffer assembly 5 includes a buffer channel 10 fixed on the top of the through groove 6 , a buffer rubber plate 11 is fixed on the inner wall of the buffer channel 10 , and the buffer rubber plate 11 is provided along each surface inside the buffer channel 10 .
[0021] Specifically, the buffer rubber plate 11 includes a fixed plate 12 fixed on the inner wall of the buffer channel 10, a buffer spring 13 is fixed to the end of the fixed plate 12 away from the buffer channel 10, and a sliding plate 14 is fixedly connected to the end of the buffer spring 13 away from the fixed plate. The sliding plate 14 is slidably connected inside the fixed plate 12.
[0022] Specifically, a conveyor belt 15 is provided at the inner end of the buffer channel 10 facing the base 1. Both ends of the conveyor belt 15 extend out of the base 1. The extended ends of the conveyor belt 15 are rotatably connected to both sides of the base 1. A motor 16 is fixed to one end of the conveyor belt 15, and the motor 16 is fixed to the side of the base 1.
[0023] Specifically, a sliding rod 17 is fixed near the base end of the auxiliary falling plate 4, and the sliding rod 17 is symmetrically arranged about the middle of the auxiliary falling plate 4.

The connecting spring 19 is fixed to the bottom of the fixed rod 18 away from the end of the sliding rod 17.
[0024] The working principle of the present invention is: when in use, after the injection molding is completed, the movable template 3 moves. After the movement, the connecting spring 19 at the bottom of the auxiliary falling plate 4 pops out, driving the auxiliary falling plate 4 to rotate, forming an inclined surface. At the same time, the wedge block 8 on the auxiliary falling plate 4 pops out under the action of the torsion spring 9, forming an angle between the auxiliary falling plate 4 and the auxiliary falling plate 4. When the product falls, it falls into the groove 7 and first contacts the buffer rubber plate 11 inside the buffer channel 10. Under the action of the buffer spring 13, the impact force of the product falling is slowed down, and at the same time, it falls into the conveyor belt 15 below. When the injection molding continues, the movable template 3 presses the auxiliary falling plate 4 down to be parallel to the upper end of the base 1 when moving, without affecting the injection molding.
[0025] Of course, the above are only typical examples of the present invention. In addition, the present invention may also have many other specific implementation methods. Any technical solutions formed by equivalent replacement or equivalent transformation fall within the scope of protection required by the present invention.
