Description

Technical Field

[0001] The scheme belongs to the technical field of plastic processing, and specifically relates to a punching and separation device. Background Art

[0002] In the process of plastic injection molding, in order to ensure that the molten plastic can fully and evenly fill all parts of the mold, the mold design includes a runner system (including main runners, branch runners and gates). These structures guide the plastic raw materials from the injection molding machine nozzle to the mold cavity. When the plastic cools and solidifies, the plastic formed by these runners and gates will not become part of the final product, but they are connected to the product part during the injection molding process to achieve the molding needs. Therefore, when the injection molding machine produces plastic products, the product is connected with the so-called "waste" (i.e., the runner and gate parts), which is a necessary arrangement in the process design to ensure molding quality and efficiency.

[0003] In the subsequent process of plastic injection molding, the product must be separated from the waste material so that the waste material can be recycled and the unfinished parts can be removed. Therefore, a punching and separation device is urgently needed to separate the product from the waste material. Utility Model Content

[0004] The purpose of this solution is to provide a punching and separation device to solve the problem of separating plastic products from waste materials.

[0005] In order to achieve the above object, the present solution provides a punching and separation device, including a frame, and also including:

[0006] A carrying plate, the carrying plate is arranged on the frame, and the carrying plate is provided with a plurality of punching grooves for placing plastic parts;

[0007] A stamping plate, wherein the stamping plate is provided with a plurality of pressing blocks matched with the punching grooves;

[0008] The driving mechanism is used to drive the stamping plate to move up and down, and the stamping plate is connected to the driving mechanism.

[0009] The principle of this solution is that the plastic parts (including waste and products) produced by the injection molding machine are placed in the punching groove on the carrier plate, and the driving mechanism drives the stamping plate to move downward, so that the pressing block on the stamping plate is pressed into the punching groove, so that the waste is punched and cut by the pressing block, thereby separating the waste from the product.

[0010] The effects of this solution are as follows: (1) The punching plate and the carrier plate cooperate with each other to punch and separate the waste and the product, thereby improving the separation efficiency. (2) The punching groove and the pressing block cooperate with each other to ensure the accuracy of the cutting, and can accurately separate the waste part from the finished product without damaging the product, thereby improving the quality of the product.

[0011] Furthermore, the punching groove includes a first through groove and four second through grooves which are symmetrically arranged and have the same structure, and the second through grooves are provided with protrusions for limiting the plastic part.

[0012] The principle and effect of this scheme are as follows: (1) When the plastic parts (including products and waste materials) are placed in the punching groove, the products are placed in the second through groove and the waste materials are placed in the first through groove. Since the second through groove is provided with a protrusion to limit the plastic products, when the waste materials in the first through groove are punched by the pressing block on the punching plate, they are separated from the products. (2) By providing the first through groove and four mutually symmetrical second through grooves, the plastic products and waste materials can be clearly distinguished when placed. At the same time, the pressing block on the punching plate only accurately punches the waste materials in the first through groove, avoiding unnecessary damage to the remaining products.

[0013] Furthermore, the stamping plate is slidably connected to a limit plate via a support shaft, and the limit plate is provided with a plurality of through slots matched with the pressing block.

[0014] The principle and effect of this solution are: when the driving mechanism drives the stamping plate and the limit plate to stamp, the limit plate will conflict with the bearing plate, and the through groove opened on the limit plate can limit the maximum stroke of the pressing block when punching downward, ensuring that the pressing block reaches the preset depth when punching the waste, ensuring that the waste can be cut off.

[0015] Furthermore, a spring is provided on the support shaft.

[0016] The principle and effect of this solution are: after the punching is completed, the driving mechanism drives the limit plate away from the bearing plate, and the spring drives the limit plate to return to its original position.

[0017] Furthermore, the driving mechanism includes a cylinder and a supporting assembly for supporting the cylinder, the supporting assembly is arranged on a frame, and the stamping plate is connected to a piston rod of the cylinder.

[0018] The principle and effect of this solution are as follows: (1) The cylinder is supported by the support assembly, and the piston rod of the cylinder is extended and retracted to drive the punching plate to move downward to punch the workpiece or move up and down to reset. (2) The cylinder is used as the driving source. The instant response capability of the pneumatic system ensures that the punching plate can be pressed down quickly and accurately when needed to complete the punching action, and it is also convenient for quick reset.

[0019] Furthermore, the support assembly includes a support arm and a support seat slidably arranged on the support arm, the cylinder is connected to the support seat, a screw is provided on the support arm, and the support seat is threadedly connected to the screw.

[0020] The principle and effect of this solution are: by rotating the screw rod, the support seat is moved up and down on the support arm to adjust the position of the cylinder and control the movement stroke of the cylinder piston rod.

[0021] Furthermore, a guide rail is provided on the support arm, and the guide rail is slidably connected to the support seat.

[0022] The principle and effect of this solution are that the support seat moves up and down on the guide rail, and the guide rail provides positioning and guiding functions for the movement of the support seat.

[0023] Furthermore, a classification screen is provided on the frame, and the classification screen is provided with classification holes matched with the products.

[0024] The principle and effect of this solution is that after the waste and the product are separated, they fall onto the classification screen by their own gravity, wherein the product falls through the classification holes, while the waste continues to slide on the classification screen and falls through the end of the classification screen.

[0025] Furthermore, the frame is provided with a waste collection bin and a product collection bin with an opening on the top, and the waste collection bin is arranged on the left side of the product collection bin.

[0026] The principle and effect of this solution are that the products passing through the classification holes fall into the product collection bin, while the waste materials slide into the waste collection bin on the left, thereby achieving classified collection of waste materials and products.

[0027] Furthermore, the frames are formed by splicing a plurality of profiles.

[0028] The principle and effect of this solution is that the rack can be disassembled and connected to facilitate assembly. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0036] The following will clearly and completely describe the concept and technical effects of the utility model in combination with the embodiments, so as to fully understand the purpose, features and effects of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of them. Based on the embodiments of the utility model, other embodiments obtained by technicians in this field without creative work are all within the scope of protection of the utility model:

[0037] Example:

[0038] See also Figure 1 and Figure 2 The punching and separation device includes, from bottom to top, a frame 1, a waste collection bin 6, a product collection bin 7, a classification screen 5, a bearing plate 2 and a driving mechanism 4; wherein the frame 1 is formed by splicing a plurality of I-beam profiles and connected by bolts.

[0039] See also Figure 3-Figure 6The carrier plate 2 is provided with a plurality of punching grooves 21 for placing workpieces (products 8 and waste materials 9). The punching grooves 21 include a first through groove 211 in the middle and four second through grooves 212 symmetrically arranged on both sides of the first through groove 211. The second through groove 212 is provided with a protrusion 213 for limiting the product. The product 8 is placed in the second through groove 212. The protrusion 213 is used to limit the product 8 and prevent the waste materials 9 from falling when being punched. The waste materials 9 are placed in the first through groove 211. By providing the first through groove 211 and the four mutually symmetrical second through grooves 212, the product 8 and the waste materials 9 can be clearly distinguished when placed. At the same time, the pressing block 31 on the stamping plate 3 only accurately punches the waste materials 9 in the first through groove 211 to avoid unnecessary damage to the remaining products 9. The stamping plate 3 is provided with a pressing block 31 which matches with the first through groove 211. The stamping plate 3 is slidably connected with the limiting plate 32 through the supporting shaft. The limiting plate 32 is provided with a plurality of through grooves 321 which match with the pressing block 31. The through grooves 321 can limit the maximum stroke of the pressing block 31 when punching downward, ensuring that the pressing block 31 reaches a preset depth when punching the waste material, and ensuring that the waste material 9 can be cut off. When the stamping plate 3 is punched downward, the pressing block 31 can slide and extend out in the through groove 321, so that it contacts the waste material 9 and punches the waste material 9, so as to separate it from the product 8. A spring 33 is provided on the supporting shaft. After the punching is completed, the driving mechanism 4 drives the limiting plate 32 away from the supporting plate 2, and the spring 33 drives the limiting plate 32 to reset.

[0040] The driving mechanism 4 includes a cylinder 41 and a supporting assembly 42 for supporting the cylinder 41. The stamping plate 3 is connected to the piston rod of the cylinder 41. The cylinder 41 is used as a driving source. It has the function of quickly pressing the stamping plate 3 downward to complete the punching action and is also convenient for rapid resetting. The cylinder 41 is electrically connected to a controller. The air intake and air exhaust of the cylinder 41 are controlled by a program pre-stored in the controller, thereby controlling the extension and retraction of the piston rod of the cylinder 41, driving the stamping plate 3 to punch the carrier plate 2 downward, and retract to reset.

[0041] The support assembly 42 is arranged on the frame 1, and the support assembly 42 includes a support arm 421 and a support seat 422. The support arm 421 is provided with a guide rail 424, and the guide rail 424 is slidably connected to the support seat 422. The support seat 422 moves up and down on the guide rail 424. The guide rail 424 provides positioning and guiding functions for the movement of the support seat 422. The cylinder 41 is connected to the support seat 422, and the support arm 421 is provided with a screw 423. The support seat 422 is threadedly connected to the screw 423. The support seat 422 is moved up and down on the support arm 421 by rotating the screw 423 to adjust the position of the cylinder 41 and control the movement stroke of the piston rod of the cylinder 41.

[0042] The frame 1 is provided with an inclined classification screen 5, and the classification screen 5 is provided with classification holes 51 that match the product 8. When the product 8 slides on the classification screen 5, it will fall through the classification holes 51, while the waste 9 will not pass through the classification holes 51 due to its shape and size, and will fall from the end of the classification screen 5. The frame 1 is also provided with a waste collection bin 6 and a product collection bin 7 with an opening on the top. The waste collection bin 6 is arranged on the left side of the product collection bin 7. The product 8 falls into the product collection bin 6 through the classification holes 51, and the waste 9 slides into the waste collection bin 6 on the left side, so as to realize the classified collection of the waste 9 and the product 8.

[0043] The above is only an embodiment of the utility model, and the common knowledge such as the known specific structure and characteristics in the scheme is not described in detail here. It should be pointed out that for those skilled in the art, several deformations and improvements can be made without departing from the structure of the utility model, which should also be regarded as the protection scope of the utility model, and these will not affect the effect of the implementation of the utility model and the practicality of the patent.
