Description

Technical Field

[0001] This utility model belongs to the field of plastic injection molding technology, and relates to a device for recycling waste material in the injection molding process of electric vehicle plastic parts. Background Technology

[0002] Traditional injection molding dies often produce overflowing material or leave small amounts of material residue on the inner wall of the mold after injection molding, resulting in material waste and affecting the cleanliness of the mold plate. To address this, existing patent publication number CN215825791U describes a material recycling device for injection molds, comprising a left mold plate, a right mold plate, a hydraulic cylinder, and an injection molding machine. A cleaning assembly is located above the left and right mold plates, including a set of symmetrically arranged cleaning rollers. Each cleaning roller is rotatably connected to a mounting base via a rotating shaft. A lifting mechanism is connected above the mounting base, and a rolling gear is fixedly connected to the outer end of the rotating shaft, meshing with a rack plate. A waste collection hood is located below the left and right mold plates, opposite to the cleaning rollers. This solution utilizes the cleaning rollers, mounting base, lifting mechanism, rolling gear, rack plate, and waste collection hood, with the rotating cleaning rollers cleaning the inner wall of the mold plate, preventing material residue and enabling its recycling.

[0003] The above-mentioned solution collects the waste material through a cleaning mechanism. However, during the collection process, the waste material of different sizes is usually filtered by screening. For example, the solution disclosed in patent publication number CN119734394A uses a filter screen for screening. However, the filter screen is prone to clogging and lacks an automatic cleaning mechanism to prevent clogging. Therefore, we have designed a waste material recycling device for the injection molding process of electric vehicle plastic parts. Summary of the Invention

[0004] The purpose of this invention is to provide a device for recycling waste material from the injection molding process of plastic parts for electric vehicles, so as to solve the problems mentioned in the background art.

[0005] The purpose of this utility model can be achieved through the following technical solution: a waste material recycling device for injection molding of plastic parts for electric vehicles, including a waste material collection box, a feeding hopper, a filter screen and a touch operation panel. The feeding hopper is installed at the material inlet at the top of the waste material collection box. The filter screen is installed on the inner opening of the feeding hopper through an elastic connecting post and communicates with the material inlet at the top of the waste material collection box. The touch operation panel is assembled on the front of the waste material collection box through a bracket. The waste material collection box is provided with a partition, and a waste material chamber is formed on one side of the partition. It also includes a filter screen striking assembly, which includes a striking shell, a crankshaft and a flywheel. The striking shell is inverted triangular and fixed to the bottom center of the filter screen. The flywheel is integrally formed and is located on the crankshaft and distributed inside the striking shell along with the crankshaft.

[0006] In the aforementioned waste material recycling device for electric vehicle plastic parts injection molding process, the filter screen striking assembly also includes a drive mechanism. The drive mechanism comprises a rack, gears, a drive shaft, and a reciprocating cylinder. The rack and gear are both located on the other side of the partition, meshing together. The reciprocating cylinder is mounted on the back of the waste material collection box and connected to the rack via an output shaft. The drive shaft is keyed to the keyway of the gear, and its end is connected to the crankshaft. This arrangement aims to apply power through the reciprocating cylinder, causing the rack to reciprocate linearly, driving the gears to rotate in both directions, thereby driving the crankshaft to rotate continuously in a reciprocating manner.

[0007] In the aforementioned device for recycling waste material from the injection molding process of electric vehicle plastic parts, the filter screen striking assembly also includes a bearing housing, the bearing portion of which is inserted and connected to the drive shaft. This arrangement aims to ensure good rotational accuracy of the drive shaft during rotation.

[0008] In the aforementioned waste material recycling device for electric vehicle plastic parts injection molding process, a rotating sleeve is installed on the top of one side of the waste material collection box, and a handle is movably installed inside the rotating sleeve; casters are installed at the four corners of the bottom of the waste material collection box. The purpose of this arrangement is to facilitate moving the waste material collection box to the waste material recycling port on the injection molding machine.

[0009] In the aforementioned waste material recycling device for electric vehicle plastic parts injection molding process, a discharge section communicating with the waste material chamber is provided on the bottom of the other side of the waste material collection box. A pad extending into the waste material chamber is provided at the bottom of the discharge section. Above the pad, a waste material drawer basket connected to the waste material chamber and corresponding to the material inlet of the waste material collection box is provided. A handle is installed on one side of the waste material drawer basket. This design allows the recycled waste material to fall into the waste material drawer basket, facilitating its removal without opening the waste material collection box, thus providing excellent ease of use.

[0010] Compared with the prior art, the advantages of this utility model of the waste material recycling device for electric vehicle plastic parts injection molding process are as follows: By using the filter screen striking assembly, which includes a striking shell, a crankshaft, and a flywheel, the striking shell is inverted triangular in shape and fixed to the bottom center of the filter screen. The flywheel is integrally formed on the crankshaft and distributed inside the striking shell along with the crankshaft. Power is applied by the set driving mechanism, which can drive the crankshaft to rotate continuously and reciprocally, thereby causing the flywheel to intermittently strike the bottom of the filter screen. Due to the elastic connection of the filter screen, the blockage at the mesh of the filter screen can be knocked out, and at the same time, it is easier to screen the material on the filter screen and avoid excessive accumulation.

[0016] The following are specific embodiments of the present invention, which are described in conjunction with the accompanying drawings. However, the present invention is not limited to these embodiments.

[0017] like Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, this utility model relates to a device for recycling waste material during the injection molding process of plastic parts for electric vehicles.

[0018] Example 1: The waste material recycling device includes a waste material collection box 1, a feed hopper 2, a filter screen 3, and a touch operation panel 6. The feed hopper 2 is installed at the material inlet at the top of the waste material collection box 1. The filter screen 3 is installed on the inner opening of the feed hopper 2 through an elastic connecting post and communicates with the material inlet at the top of the waste material collection box 1. The touch operation panel 6 is assembled on the front of the waste material collection box 1 through a bracket. The waste material collection box 1 is provided with a partition 8 inside. A waste material chamber 9 is formed on one side of the partition 8. It also includes a filter screen striking assembly. The filter screen striking assembly includes a striking shell 10, a crank connecting shaft 14, and a flywheel 15. The striking shell 10 is inverted triangular and fixed to the bottom center of the filter screen 3. The flywheel 15 is integrally formed on the crank connecting shaft 14 and is distributed inside the striking shell 10 along with the crank connecting shaft 14.

[0019] Furthermore, such as Figure 2As shown, the filter screen striking assembly also includes a drive mechanism, which includes a rack 11, a gear 12, a drive shaft 13, and a reciprocating cylinder 17. The rack 11 and gear 12 are both located on the other side of the partition 8, and the rack 11 and gear 12 are meshed together. The reciprocating cylinder 17 is installed on the back of the waste material collection box 1 and is connected to the rack 11 through an output shaft. The drive shaft 13 is keyed to the keyway of the gear 12, and the end of the drive shaft 13 is connected to the crankshaft 14.

[0020] Working principle: When some residual material accumulates on the filter screen 3, or when it becomes clogged, the reciprocating cylinder 17 applies power, causing the rack 11 to reciprocate linearly, which drives the gear 12 to rotate in both directions. This, in turn, drives the crankshaft 14 to rotate continuously, causing the flywheel 15 to intermittently strike the bottom of the filter screen 3. Due to the elastic connection of the filter screen 3, the blockage at the mesh of the filter screen 3 can be knocked out, which also facilitates better screening of the material on the filter screen 3 and avoids excessive accumulation.
