Description

Technical Field

[0001] The utility model relates to the field of chemical waste gas treatment equipment, in particular to a chip removing device for a horizontal injection molding machine. Background Technique

[0002] An injection molding machine is also known as an injection molding machine or an injection machine. It is the main molding equipment for making various shaped plastic products from thermoplastic or thermosetting plastics using plastic molding dies. The injection molding machine can heat the plastic, apply high pressure to the molten plastic, and inject it to fill the mold cavity. It is generally divided into vertical and horizontal types.

[0003] A horizontal injection molding machine is a form of injection molding machine, usually composed of an injection system, a mold clamping system, a hydraulic transmission system, an electrical control system, a heating and cooling system, etc. Its working process is as follows: the injection system melts the plastic, the mold clamping system fixes the mold, the transmission system and the electrical system control the sliding docking of the injection head and the mold, the screw injects the molten plastic into the mold cavity, the mold is cooled after injection, and then the mold is opened to eject the injection molded part.

[0004] Due to the relatively large injection pressure during injection, strip-shaped plastic will overflow at the edge where the injection head and the mold are docked. After cooling in the air, it will form strip-shaped chips. These chips generally rest at the docking port of the mold clamping system or fall to the bottom of the mold clamping system. In order not to affect the normal operation of the equipment, after 2-3 injections, workers need to manually pick out the chips. Manually picking up the chips is time-consuming and laborious, and there are certain safety hazards. This is the existing problem. Content of the Utility Model

[0005] In order to make up for the deficiencies of the prior art, the utility model provides a chip removing device for a horizontal injection molding machine to improve the above problems.

[0006] The utility model is realized by the following technical solutions:

[0007] A chip removing device for a horizontal injection molding machine includes an injection barrel and a lock template. A mold is locked in the lock template. A positioning plate is fixed between the lock template and the injection barrel. The injection barrel passes through the positioning plate and docks with the mold for injection. A positioning hole is formed on the positioning plate. The positioning hole is bowl-shaped and the large opening faces to the right. A first collection box is arranged below the right side of the positioning plate, and a second collection box is arranged below the left side of the positioning plate. The second collection box is located directly below the docking and injection position of the injection barrel and the mold. A screen box is arranged in the second collection box, and an air outlet pipe is arranged below the screen box. The air outlet pipe is connected to an external fan.

[0008] Further optimized, the tops of the first collection box and the second collection box are open.

[0009] Further optimized, the upper edge of the second collection box is lower than the lower edge of the locking template.

[0010] Further optimized, a scraping plate is provided at the head of the injection barrel.

[0011] Further optimized, support rails are provided on the inner sides of the front wall, rear wall and right wall of the second collection box, and the screen box is slidably arranged on the second collection box.

[0012] Further optimized, the screen box includes a box body, a screen and a sliding panel. The top of the box body is open. The screen is fixed on the lower wall and the left wall of the box body. An air duct is provided between the screen on the left wall and the sliding panel.

[0013] Further optimized, a sealing strip is provided on the inner side of the sliding panel.

[0014] The beneficial effects of the present utility model are as follows:

[0015] In this device, the first and second collection boxes are arranged on both sides of the positioning plate. The second collection box is located below the injection barrel and the mold injection position. During the injection process, the overflowed plastic naturally cools into debris, and the naturally fallen debris and the debris stuck on the injection head are sucked into the second collection box under the action of air flow suction; the relatively firmly stuck debris on the injection head will also naturally fall during subsequent repeated injection processes. Therefore, a first collection box is provided below the injection barrel on the right side of the positioning plate to collect the debris that naturally falls during the stroke of the injection barrel. Through this device, the staff only needs to regularly clean the debris in the collection box during downtime, without manual picking.

[0016] In this device, the second collection box is located below the injection barrel and the mold injection position. While attracting debris by connecting to an external fan, it can also absorb the waste gas generated during the injection process, which plays a certain role in purifying the working environment.

In the description of the present utility model, it should be noted that the orientation or positional relationship indicated by terms such as "left", "right", "front", "rear", "inner", "outer", etc. is based on the orientation or positional relationship shown in the attached drawings. It is only for the convenience of describing the present utility model and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be construed as a limitation to the present utility model.

[0027] As Figures 1 - 8 shown, the present utility model provides a dandruff removal device for a horizontal injection molding machine, including an injection barrel 1 and a clamping plate 2. A mold is clamped inside the clamping plate 2. A positioning plate 3 is fixed between the clamping plate 2 and the injection barrel 1. A positioning hole 6 is opened on the positioning plate. Under the control of the transmission system, the injection barrel 1 and the mold pass through the positioning plate to be docked for injection molding.

[0028] The positioning hole 6 is bowl-shaped, as Figure 3 shown, and the large opening faces to the right, that is, towards the injection barrel side. A first collection box 4 is provided below the right side of the positioning plate 3. The relatively firmly adhered debris on the injection head will also naturally fall during subsequent repeated injection molding processes. The first collection box is used to collect the debris that naturally falls during the stroke of the injection barrel. Among them, a scraper 12 is provided at the head of the injection barrel. The scraper is made of heat-resistant material. The function of the scraper is to prevent debris from staying on the positioning hole 6. Cooperating with the bowl-shaped positioning hole, the debris can naturally slide into the first collection box during the accumulation process.

[0029] A second collection box 5 is provided below the left side of the positioning plate 3. The second collection box is directly below the docking and injection molding position of the injection barrel 1 and the mold. A screen box 51 is provided inside the second collection box 5. An air outlet pipe 52 is provided below the screen box. The air outlet pipe 52 is connected to an external fan. During the injection molding process, the overflowing plastic naturally cools into debris. The debris that naturally falls and the debris sticking to the injection head are sucked into the second collection box under the action of air flow suction. With this device, the staff only needs to regularly clean the debris in the collection box during downtime, without manual picking. It can also absorb the waste gas generated during the injection molding process while attracting the debris, which plays a certain role in purifying the working environment.

[0030] As a preferred implementation manner, both the first collection box 4 and the second collection box 5 are open at the top for collecting debris. The upper edge of the second collection box 5 is lower than the lower edge of the lock template to prevent the collection box from affecting the left - right sliding of the lock template.

[0031] As a preferred implementation manner, support rails 53 are provided on the inner sides of the front wall, rear wall, and right wall of the second collection box 5. The screen box 51 is slidably arranged on the second collection box 5. The screen box includes a box body 513, a screen 512, and a sliding panel 511. As Figure 8 shown, the top of the box body is open. The screen 512 is fixed on the lower wall and the left wall of the box body. An air duct 514 is provided between the screen on the left wall and the sliding panel. The air outlet in two directions can prevent the bottom from being filled with debris and affecting the air outlet, thereby affecting the debris removal effect.

[0032] As a preferred implementation manner, a sealing strip 515 is provided on the inner side of the sliding panel 511.
