Abstract
Description
Technical Field
[0001] The invention relates to the technical field of injection molding, and in particular to a plastic molding device for barrel-shaped plastic products. Background Art
[0002] Plastic products such as plastic barrels, plastic bowls, plastic boxes, etc. are processed and formed by thermoforming machines. During the processing, the plastic granules are pulled and transported by the conveyor track mechanism, so that the plastic masterbatch enters each station for processing. For example, it enters the heating station and is softened by the heating device (including upper and lower heating boxes). After softening, the particles are continuously transported and then enter the molding station to be molded by the molding device. When the barrel-shaped plastic products are injected, in order to reduce the injection dead angle and ensure uniform injection molding, the injection port is usually selected at the bottom of the barrel.
[0003] After searching, it is found that the existing injection molded barrel products usually have a protruding rod reserved on the outer wall of the barrel bottom after molding, that is, a long piece of waste remaining at the injection port after cooling, which needs to be removed later. This injection molding process will not only cause a lot of waste when producing large quantities of barrel-shaped products, but also consume labor time. Therefore, we propose a new type of injection molding device. Summary of the invention
[0004] In order to achieve the above-mentioned purpose, the present invention adopts the following technical scheme: a barrel-shaped plastic product plastic molding device, including a mounting base, the mounting base is in an overall rectangular structure, and the upper part of the mounting base is divided into an injection molding section and a discharge end, a support base is fixed on the upper surface of the injection molding section of the mounting base, and an injection molding machine is fixed on the top of the support base, a mother mold is fixed on the upper surface of the support base at the injection molding outlet of the injection molding machine, and an auxiliary heater is arranged between the injection molding machine and the feeding port of the mother mold, and two grooves with openings facing each other and parallel to each other are fixed on the upper surface of the upper surface of the mounting base away from the injection molding machine The invention relates to a groove-shaped slide rail, and a discharge mechanism is arranged between the two groove-shaped slide rails, the discharge mechanism comprises a sliding carrier plate slidably connected between the two groove-shaped slide rails, a notch is opened at the end of the sliding carrier plate away from the injection molding machine, and a folding push block is hingedly connected to the upper surface of the sliding carrier plate near the edge of the notch, a male mold head is fixed to the top of the folding push block, a sliding hole is reserved in the middle of the male mold head, and a push rod is slidably connected in the sliding hole, an embedded discharge block is reserved at the end of the push rod close to the female mold, an annular retaining ring is fixed at the end of the push rod away from the embedded discharge block, and a tightening spring is arranged between the annular retaining ring and the male mold head.
[0005] A further configuration is that the injection molding machine includes a heating barrel with an overall barrel-shaped structure, a bottom cover with an annular structure is fixed at the barrel mouth of the heating barrel, a bearing is arranged in the middle of the bottom cover, and a spiral propulsion mechanism is rotatably connected in the bearing, a driven pulley is fixed to the end of the spiral propulsion mechanism away from the discharge port, a driving mechanism is arranged on the upper surface of the mounting base below the driven pulley, and an active pulley is fixed to the top end of the output shaft of the driving mechanism to form a transmission connection with the driven pulley, and an upper hopper is arranged on the circumferential outer wall of the heating barrel near the bottom cover; the injection molding machine is a double-layer barrel with an electric heating wire arranged in the middle, and the double-layer barrel injection molding machine can ensure that the injection molding machine keeps the internal plastic masterbatch in a fluid state during injection molding.
[0006] A further configuration is that the auxiliary heater is annular in structure as a whole, and an annular heater is fixed inside the auxiliary heater. The width of the annular heater acts on the bottom of the barrel, thereby continuously heating the plastic at the jet port position to avoid sticking to the finished plastic barrel due to excessive cooling, thereby reducing the length of the rod attached to the traditional plastic barrel to reduce waste.

The electric push rod 2 arranged in the barrel can drive the sliding carrier and the male mold head arranged above it to close the mold and unload the materials.
[0008] A further configuration is that an arc-shaped rack is fixed on the front side of the folding push block near the top, and a servo motor is fixed on the upper surface of the sliding carrier near the periphery of the arc-shaped rack, a driving gear meshing with the arc-shaped rack is fixed on the top of the output shaft of the servo motor, and a hinge is fixed between the lower surface of the folding push block and the notch of the sliding carrier, and the rotation center of the arc-shaped rack is colinear with the rotation axis of the hinge.

[0010] A further arrangement is that a groove is provided below the notch at one end of the sliding carrier away from the injection molding machine, and a magnet suction block is embedded in the groove; through the provided magnet suction block, the folding push block can be tightly adsorbed and fixed when the folding push block is rotated to a vertical state, which is conducive to stable material removal.
[0011] A further configuration is that a horizontal through hole is opened on the inclined surface of the folding push block, and the through hole is coaxially distributed with the push rod, and the push rod is slidably connected in the through hole; the push rod can always maintain axial movement when sliding, so as to ensure that the gap around the embedded discharge block at its end is very small.

[0013] A further configuration is that a mounting plate is fixed to one end of the side of the mounting base away from the injection molding machine, and a rotating mechanism is fixed to the upper surface of the mounting plate, a rotatable electric push rod is arranged at the top of the rotating mechanism, a turntable is fixed to the top of the extension rod of the electric push rod, two horizontally extending extension arms are fixed to the circumferential outer wall of the turntable, a buffer telescopic tube and a grinder are respectively fixed at the same distance positions at the ends of the two extension arms, a suction cup is fixed to the bottom end of the buffer telescopic tube, a saw blade is fixed to the top of the output shaft of the grinder; an air suction machine adapted to the suction cup is fixed to the top of the turntable; by means of the arranged suction cup and grinder, the grinding of the bottom protrusion and the adsorption of the finished plastic barrel can be completed by rotating back and forth, and then the finished plastic barrel can be taken out by lifting the whole.
[0014] The beneficial effects of the present invention are: 1. By installing an auxiliary heater at the outlet of the injection molding machine, the plastic at the injection port can be continuously heated when the injection molding is completed and the material is ready for unloading, ensuring that the plastic raw material at the discharge port will not solidify. At this time, demolding can reduce the length of the residue on the outer wall of the bottom of the plastic barrel. In addition, by installing an embedded discharge block at the end of the ejector rod, if the finished plastic barrel sticks to the outer wall of the male mold head and is not easy to fall off, you only need to push the ejector rod from the back.
[0015] 2. The plastic at the jet port is continuously heated to prevent it from being bonded to the finished plastic barrel due to excessive cooling, thereby reducing the length of the rod attached to the traditional plastic barrel to reduce waste.
[0016] 3. By setting the lifting block, the folding push block can be rotated from a horizontal state to a vertical state, and the push rod can be pushed upward for a distance, thereby completing the discharging action, that is, lifting the finished plastic barrel to help demoulding.
