Description

Technical Field

[0001] The invention relates to the field of plastic parts processing equipment, in particular to a plastic parts damage making device. Background Art

[0002] In the quality inspection or performance evaluation of plastic parts, it is often necessary to simulate the damage that may occur in the actual use environment. At present, most of the plastic parts damage production equipment on the market has a single function and cannot meet the production needs of various types of damage. In addition, the operation is complicated and the efficiency is low. Therefore, it is of great significance to develop a plastic parts damage production device with stable structure, diverse functions and easy operation. Utility Model Content

[0003] In order to overcome the problems existing in the prior art, the utility model aims to provide a plastic part damage making device.

[0004] The technical solution adopted by the utility model to solve its technical problems is: a plastic part damage maker, comprising: a fixed bracket, a cylinder, a tool group, a tool clamping part, a tool storage part, a demoulding part and a mold; the two ends of the fixed bracket are respectively connected to the cylinder and the mold, and the driving end of the cylinder is arranged opposite to the mold; the tool storage part is arranged at one end of the fixed bracket close to the cylinder, and the tool group is installed in the tool storage part, and no less than one tool head is arranged in the tool group; the tool clamping part is connected to the driving end of the cylinder, and a mounting cavity for fixing the tool head is provided in the middle of the tool clamping part; the demoulding part is installed on the side of the tool clamping part away from the cylinder, and the demoulding part is connected to the cylinder body part of the cylinder.

[0005] Its main working principle is that, first, the tool head in the tool set is placed in the tool storage part. According to the processing requirements, a suitable tool head is selected. This tool head is then fixed in the mounting cavity of the tool clamping part. The tool clamping part is connected to the drive end of the cylinder, so when the cylinder is working, its drive end will drive the tool clamping part and the tool head fixed on it to move up and down. The fixed bracket serves as the basis of the entire device, and its two ends are connected to the cylinder and the mold respectively. This design ensures the relative position stability between the cylinder, the tool clamping part and the mold, thereby ensuring the processing accuracy. The mold is used to place the plastic part to be processed. When the plastic part is placed in the mold, the cylinder starts to work. The drive end of the cylinder moves downward, driving the tool clamping part and the tool head on it to move downward together. When the tool head contacts the plastic part, it starts to cut or damage the plastic part. The demoulding part is installed on the side of the tool clamping part away from the cylinder and is connected to the cylinder body part of the cylinder. The design of the demoulding part helps the plastic part to be smoothly removed from the mold after the processing is completed. When the driving end of the cylinder retracts, it drives the tool clamping part and the cutter head to move upward. At this time, due to the existence of the demoulding part, the plastic part can be smoothly separated from the cutter head and ejected from the mold.

[0030] In order to more clearly understand the above-mentioned purposes, features and advantages of the utility model, the utility model is described in detail below in conjunction with the accompanying drawings and specific embodiments. It should be noted that, in the absence of conflict, the embodiments of the present application and the features in the embodiments can be combined with each other. In the following description, many specific details are set forth in order to fully understand the utility model, and the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the utility model.

[0031] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as those commonly understood by those skilled in the art of the present invention. The terms used herein in the specification of the present invention are only for the purpose of describing specific embodiments and are not intended to limit the present invention.

[0032] The utility model relates to a plastic part damage generator, which is mainly used to simulate the damage that a plastic part may suffer in an actual use environment, so as to perform quality inspection or performance evaluation. The utility model will be described in detail below in conjunction with the accompanying drawings.

[0033] First, the plastic parts damage the main components of the maker, such as Figure 1-Figure 7 As shown, the plastic part damage maker mainly includes a fixed bracket 1, a cylinder 2, a tool group 3, a tool clamping part 4, a tool storage part 5, a demoulding part 6 and a mold 7. These components work together to achieve damage production of plastic parts. Among them, the fixed bracket 1 is the basic structure of the entire maker, and adopts a combination design of a "["-shaped bracket 10 and a bottom plate 11. The "["-shaped bracket 10 is arranged perpendicular to the horizontal plane, providing stable support for other components. The bottom plate 11 is arranged at the lower end of the "["-shaped bracket 10, which not only increases the stability of the entire maker, but also facilitates connection with the ground or other fixed structures, providing an installation platform. The cylinder 2 is installed at the upper end of the "["-shaped bracket 10, and a tool storage part 5 is arranged on the upper surface of the "["-shaped bracket 10. The tool group 3 is installed in the tool storage part 5, and different tool heads can be replaced at any time as needed. The tool storage part is arranged near the cylinder 2, so that the tool head can be replaced easily. The tool set 3 includes at least a "T"-shaped tool head 30, an "L"-shaped tool head 31, and an "I"-shaped tool head 32 to meet the needs of different damage production. In the non-operating state, these tool heads are placed in the tool storage part 5 for easy management and storage. The tool clamping part 4 is connected to the driving end of the cylinder 2, and a mounting cavity 40 is provided in the middle thereof for fixing the selected tool head. When working, the corresponding tool head is installed in the mounting cavity 40 of the tool clamping part 4, and the driving end of the cylinder 2 will drive the tool clamping part 4 and the selected tool head to move together to realize the damage production of the tool head on the plastic part.

[0034] The demoulding part 6 is installed on the side of the tool clamping part 4 away from the cylinder 2, and is connected to the cylinder body of the cylinder 2. During the working process, a through hole 60 is provided in the middle of the demoulding part 6 for the cutter head to pass through, so as to avoid interference between the cutter head and the demoulding part 6 and ensure the smooth progress of the processing process. At the same time, when the cutter head shrinks inward, if the plastic part cannot fall off naturally due to the mutual combination between the plastic part and the cutter head, when the plastic part contacts the demoulding part 6, the demoulding part 6 will block the plastic part. As the cutter head retreats further, the plastic part falls off under the blockage of the demoulding part 6. The design of the demoulding part 6 enables the plastic part to be smoothly removed from the mold 7 after the processing is completed, avoiding damage or product scrapping caused by demoulding difficulties.

[0035] The mold 7 is a component for placing the plastic parts to be processed. The mold 7 itself is a cube. The cube mold 7 is provided with three working surfaces. The three working surfaces are respectively provided with a "T"-shaped groove 70, an "L"-shaped groove 71 and an "I"-shaped groove 72, which correspond to the "T"-shaped cutter head 30, the "L"-shaped cutter head 31 and the "I"-shaped cutter head 32. Therefore, even if the cutter head is replaced, there is no need to replace the mold 7. It is only necessary to flip and adjust the working surface of the mold 7 so that the cutter head can accurately damage the plastic parts. The mold 7 is fixed by a baffle 92 on the upper surface of the bottom plate 11. The baffle 92 is arranged around the mold 7 to form a protective area to prevent the plastic parts or the cutter head from causing damage to the operator during the processing. Tightening screws 93 are arranged on the periphery of the baffle 92 to facilitate the fixing and adjustment of the mold 7.

[0036] In some optional embodiments, in order to achieve accurate control of the working pressure of the cylinder 2, a pressure regulator 90 and a pressure gauge 91 are also included. Both components are arranged on the fixed bracket 1, so that the operator can observe and adjust the working pressure of the cylinder 2 at any time. By adjusting the pressure regulator 90, it can be ensured that the cylinder 2 provides a stable driving force during the processing, thereby achieving accurate damage production.

[0037] In some optional embodiments, in order to improve the stability and accuracy of the maker, the design of guide sleeves 80 and guide posts 81 is also adopted. Specifically, guide sleeves 80 (or guide posts 81) are provided at the four end corners of the flange 8, and guide posts 81 (or guide sleeves 80) matched therewith are provided at the four end corners of the tool clamping part 4. This design enables the tool clamping part 4 to maintain a stable trajectory and direction during the movement, thereby improving the processing accuracy and product quality.

[0038] In some optional embodiments, in order to facilitate the installation and fixation of the demoulding portion 6, the present invention further provides four positioning rods 82 on the flange 8. These positioning rods 82 are arranged perpendicular to the horizontal plane and are fixedly connected to the four end corners of the demoulding portion 6. This design not only simplifies the installation process of the demoulding portion 6, but also improves its stability and reliability.

[0039] In summary, the operator first selects a suitable cutter head according to the processing requirements and installs it in the mounting cavity 40 of the tool clamping part 4. Then, the plastic part to be processed is placed in the mold 7 and fixed by tightening the screws 93 and the baffle 92. Next, the working pressure of the cylinder 2 is adjusted to a suitable value by the pressure regulator 90. After starting the cylinder 2, its driving end will drive the tool clamping part 4 and the selected cutter head to move downward, causing damage to the plastic part. After the processing is completed, the driving end of the cylinder 2 retracts, driving the tool clamping part 4 and the cutter head to move upward, and the plastic part is smoothly demolded under the action of the demolding part 6.

[0040] The plastic part damage making device of the utility model has the advantages of simple structure, convenient operation, and multiple functions. By replacing different cutter heads, damage making of different shapes and sizes of plastic parts can be achieved to meet different processing requirements. At the same time, the making device also has high stability and precision, which can ensure the smooth progress of the processing process and the stable and reliable product quality.

[0041] The above description is only a preferred embodiment of the present invention and does not constitute any form of limitation to the present invention. Therefore, any modification, equivalent changes and modifications made to the above embodiments based on the technical essence of the present invention without departing from the technical solution of the present invention are still within the scope of the technical solution of the present invention.
