Description

Technical Field

[0001] The utility model relates to the technical field of spraying tooling, and more specifically, to a spraying plastic tooling. Background Technique

[0002] A spraying tooling is an auxiliary tool or device used in the spraying process to ensure that the workpiece to be sprayed is in an accurate position during the spraying process, prevent movement or deformation, so as to ensure the uniformity and accuracy of spraying. For example, in the spraying of automobile parts, a specific tooling can firmly fix the parts at a specific angle and position.

[0003] However, in the traditional paint spraying process, iron tooling is generally used as the product installation bracket for paint spraying. However, the production of iron tooling is cumbersome, the use cost is high, and the production quality is low. The main problems are as follows: the tooling needs to be cleaned regularly with a paint remover. After cleaning, the iron tooling is prone to oxidation and rust, and it will cause rust powder to pollute the production line. Moreover, each time the tooling is cleaned, its disassembly is extremely inconvenient, and the iron tooling is also difficult to handle due to its heavy weight, causing many inconveniences in actual use.

[0004] And when positioning the production product, usually a single positioning block and positioning column are used to clamp and position the workpiece, and the positioning stability is not ideal, and it is extremely easy to cause deviation during the spraying process, which will affect the spraying effect and product quality, bringing great troubles to actual use.

[0005] In view of this, we propose a spraying plastic tooling. Content of the Utility Model

[0006] 1. Technical Problems to be Solved

[0007] The purpose of the utility model is to provide a spraying plastic tooling to solve the problems of inconvenient cleaning, easy oxidation and rust of the iron tooling after cleaning, rust powder pollution of the production line and poor positioning stability mentioned in the above background technique.

[0008] 2. Technical Solution

[0009] A spraying plastic tooling includes a fixed seat. A clamping interface and a clamping circular groove are opened at the top of the fixed seat. A plastic mold is clamped inside the clamping interface and the clamping circular groove. A positioning block one and a positioning block two are arranged at the top of the plastic mold. A clamping block and a limiting component are arranged at the bottom of the plastic mold. The clamping block is matched with the clamping interface. The limiting component includes a connecting block. A production product is clamped and positioned at the top of the plastic mold.

[0010] Preferably, positioning tubes are arranged at the tops of multiple clamping blocks, and the clamping blocks and the positioning tubes are mutually communicated.

[0011] Preferably, a vacuum suction pipe is provided on the side wall of the fixing base, a cavity is formed inside the fixing base, and the bottoms of the plurality of card interfaces are through-type and communicate with the cavity.

[0012] Preferably, a fixing rod is provided at the bottom of the inner cavity of the clamping circular groove, a fixing conical block is provided at the top, and a sleeved conical block is sleeved on the circumferential outer wall of the fixing rod.

[0013] Preferably, a first spring is provided at the top of the inner cavity of the connecting block, a movable plate is connected to the ends of the plurality of first springs, a pressing block is provided at the top of the movable plate, and a connecting rod is provided at the bottom of the movable plate.

[0014] Preferably, a fixed circular block is provided at the bottom of the connecting rod, a groove is formed at the bottom of the fixed circular block, and a cavity is formed inside the fixed circular block.

[0015] Preferably, a second spring is provided on the inner walls of the plurality of cavities, a limiting block is connected to the ends of the plurality of second springs, and an inclined surface is formed on one side of the plurality of limiting blocks.

[0016] 3. Beneficial effects

[0017] Compared with the prior art, the advantages of the present utility model are as follows: when it is necessary to disassemble the plastic mold, only need to press down the pressing block. At this time, the pressing block will drive the connecting rod carrying the fixed circular block to descend, so that the limiting block inside the cavity of the fixed circular block moves to the bottom of the sleeved conical block. At this time, release the pressing block, and then the pressing block will rebound due to the action of the first spring. During the rebounding process, the two limiting blocks will drive the sleeved conical block to move upward. When the top of the sleeved conical block fits with the bottom of the fixed conical block, the two limiting blocks will smoothly pass through the fixed conical block, and then the plastic mold can be disassembled. Conversely, during installation, only need to maintain the positions of the two limiting blocks between the fixed conical block and the sleeved conical block to limit it. The overall disassembly and installation are relatively simple, and the plastic mold is lighter than the metal mold, so it is also more labor-saving during transportation and cleaning. Secondly, it can also better avoid the generation of rust, reduce the secondary pollution of the production line, and improve the production quality of the production line;

[0018] And when positioning, clamping and spraying the production product, the positioning pipes on the tops of the plurality of clamping blocks can cooperate with the plurality of first positioning blocks and second positioning blocks to initially position the product. Then, the cavity inside the fixing base is changed into a vacuum cavity by an external vacuum pump. At this time, the plurality of positioning pipes will generate an adsorption force due to the vacuum effect, and then further vacuum adsorb and fix the production product to improve the stability of the product during spraying and reduce the risk of its deviation and falling off.

[0029] In some embodiments: After the plastic mold 200 is completed by digital simulation, it is supported by an injection mold, which belongs to the prior art, and its connecting block 240 can be fixed by hot melt welding after the equipment parts are installed.

[0030] A clamping block 230 and a limiting component are arranged at the bottom of the plastic mold 200, the clamping block 230 matches the clamping interface 120, the limiting component includes a connecting block 240, and a production product 400 is clamped and positioned at the top of the plastic mold 200.

[0031] In some embodiments: The bottom of the production product 400 matches the first positioning block 210, the second positioning block 220 and the positioning tube 231. When positioning and spraying workpieces of different shapes are produced, a suitable plastic mold 230 can be replaced for positioning use.

[0032] Specifically, positioning tubes 231 are arranged at the tops of multiple clamping blocks 230, and the clamping blocks 230 and the positioning tubes 231 communicate with each other.
