Description

Technical Field

[0001] The invention relates to the field of pipe fitting production, and in particular to a mould for producing three-way pipe fittings. Background Art

[0002] A compression mold with application number CN201510051448.0 is mainly used for compression molding of plastics with poor thermoplastic fluidity such as wear-resistant and corrosion-resistant plastics. It includes a core and an outer mold spaced apart from the core at the periphery of the core. The cavity between the outer mold and the core constitutes the cavity of the mold. The outer mold is provided with at least two pressing molds. The pressing mold and the outer mold form a relative sliding fit and the pressing mold extrudes the cavity. The pressing molds are arranged away from each other at the periphery of the cavity. The invention adopts a multi-directional pressurized composite molding technology, so that thermoplastic plastics with poor fluidity can be pressurized gradually and evenly from multiple directions during molding, and the molten plastic is pressed into the cavity. It solves the problems of poor pressure transmission, low pressure at a distance from the pressure head, loose plastic, and inability to form during unidirectional molding of plastics with poor fluidity, and significantly improves the quality and authenticity of molded products.

[0003] In the prior art including the above-mentioned patent, after the three-way pipe is compression molded, the material needs to be cooled and shaped in time. The traditional method is to open the mold and spray water on the surface of the material through a water gun to cool it down, and then pull out the ejector pins from the formed three-way pipe in sequence after cooling; therefore, although the surface of the three-way pipe has been cooled, the temperature of the inner wall of the pipe cannot be cooled down in a short time, and it needs to be rinsed for a long time. If the ejector pin inside the three-way pipe that has not been completely cooled is pulled out, the internal wall of the three-way pipe will be deformed, affecting the product quality. Therefore, the cooling and molding speed of the three-way pipe produced by the existing equipment is slow and the processing efficiency is low.

[0004] Therefore, it is necessary to invent a three-way pipe fitting production mold to solve the above problems. Summary of the invention

[0051] Working principle: Start the driving device 3 to press the raw material;

[0052] In the first step, when the upper mold 2 is pressed downward to the bottom, the double-sided rack 23 at the bottom of the upper mold 2 moves synchronously to the bottom, driving the second gear roller 4 to rotate, and the linkage rack 124 at the adjacent position is driven to move by the second gear roller 4, and the movement of the linkage rack 124 drives the ejector rod 12 connected thereto to move toward the center, so that the ends of the multiple ejector rods 12 that are close to each other collide with each other. At this time, the heated raw material is injected into the injection mold cavity through the feed port;

[0053] In the second step, the feeding assembly 13 and the mandrel 12 are installed with each other, and water is input into the inner cavity of the mandrel 12 through the liquid inlet end. The water flows from the bottom to the top of the diverter plate 121 and is discharged from the liquid outlet end. In the process, the mandrel 12 is cooled.

In this cycle, the inner wall of the tee pipe can be quickly cooled, so that it can be formed in a short time.

[0054] The third step is to start the driving device 3 to pull the upper die set 2 to move toward the top to open the die.

[0055] Step 4: Start the electric lifting rod 112 to drive the discharge base 111 to move toward the top to push the molded three-way pipe out of the injection molding cavity to complete the discharge;

[0056] It should be noted that in the above process:

[0057] 1. Multiple ejector pins 12 are driven by the double-sided rack 23 to be synchronously pulled out from the inner wall of the tee pipe, thus avoiding the cumbersome process of manually pulling out the ejector pins 12 one by one after cooling, simplifying the material discharging steps, improving the processing efficiency, and reducing the manual labor;

[0058] Second, when the linkage rack 124 is pulled out from the inner wall of the tee pipe along with the movement of the ejector rod 12, the gate plate 125 sealing the drain port is also driven to move, thereby opening the drain port. The water flow sprayed and flushed by the shower nozzle 213 can be discharged through the drain port. In the process, the impurities in the injection molding cavity are discharged, thereby achieving the effect of cleaning the inner wall of the injection molding cavity.

[0059] 3. The material conveying assembly 13 is detachably mounted on the top rod 12, so that the equipment can selectively install the material conveying assembly 13 according to different processing environments, thereby improving the practicability of the equipment.
