Description

Technical Field

[0001] The utility model relates to the technical field of injection molding, in particular to a feeding pipe assembly with a valve for realizing feeding without a vacuum period. Background Art

[0002] Injection molding is a method of producing industrial products. Products usually use rubber injection molding and plastic injection molding. Injection molding can also be divided into injection molding and die casting. Injection molding machine (referred to as injection machine or injection molding machine) is the main molding equipment that uses plastic molding molds to make plastic products of various shapes from thermoplastics or thermosetting materials. Injection molding is achieved through injection molding machines and molds.

[0003] Plastic particles are one of the common production materials of injection molding machines. Before the plastic particles are fed into the injection molding machine, they need to be put into the material box, so as to facilitate the addition of auxiliary materials therein, and then the plastic particles are sucked into the melting bin of the injection molding machine through the feeding pipe with a pump. After the melting bin melts the plastic particles, a fluid is formed and enters the extrusion screw of the injection molding machine. The applicant found in actual production that in order to facilitate the manual feeding of plastic particles into the material box, the material box is usually placed on the ground, and the height of the injection molding machine is much higher than the material box. In this case, there will be a height difference when the feeding pipe with a pump vacuum sucks the plastic particles. Because of the existence of the height difference, when the feeding pipe with a pump stops feeding, the plastic particles in the feeding pipe with a pump will instantly fall back into the material box. Because of the return of the plastic particles, the feeding pipe will be broken. In this way, when the feeding pipe with a pump is opened for the second time, the plastic particles cannot be fed into the melting bin of the injection molding machine in time, which reduces the production efficiency. Utility Model Content

[0004] In order to improve the above problems, the utility model discloses a feeding pipe assembly with a valve for realizing feeding without a vacuum period, which is connected between a material box and a melting chamber of an injection molding machine, and the plastic particles are located in the material box, comprising:

[0005] A feeding pipe with a pump is connected between the material box and the melting chamber of the injection molding machine. The horizontal height of the feeding pipe with a pump close to the material box is lower than the horizontal height of the feeding pipe with a pump close to the melting chamber of the injection molding machine;

[0006] Electronic stop valve: The electronic stop valve is installed on the feeding pipe with pump close to the material box end.

[0007] Preferably, it also includes:

[0008] Auxiliary fixing components, two sets of auxiliary fixing components are symmetrically installed on the top of the material box, and the electronic stop valve is clamped between the two sets of auxiliary fixing components.

[0013] A fixing buckle, the fixing buckle is installed at the end of the clamping block away from the electronic stop valve;

[0014] A wedge-shaped block is installed on the vertical pole, and the bottom end of the fixing buckle is against the inclined surface of the wedge-shaped block.

[0018] Preferably, a mounting plate is connected to the side end of the L-shaped mounting seat near the bottom end, a waist-shaped hole is opened on the mounting plate, and a fixing bolt is installed on the top of the material box and connected to the waist-shaped hole.

[0019] Compared with the prior art, the beneficial effects of the utility model are as follows:

[0020] 1. The utility model provides a valved feeding pipe assembly for realizing feeding without vacuum period. When the feeding pipe with pump stops working, the electronic stop valve also stops working. After the electronic stop valve is closed, the plastic particles in the feeding pipe with pump cannot fall back into the material box. There will be no material breakage in the feeding pipe. In this way, when the feeding pipe with pump is opened for the second time, the plastic particles can be delivered to the melting bin of the injection molding machine in time, thereby improving production efficiency. The feeding pipe with pump is equipped with an electronic stop valve near the end of the material box. When the feeding pipe with pump works, the plastic particles in the material box are delivered to the melting bin of the injection molding machine by the feeding pipe with pump. When the feeding pipe with pump stops working, the electronic stop valve also stops working. After the electronic stop valve is closed, the plastic particles in the feeding pipe with pump cannot fall back into the material box.

[0021] 2. The utility model provides a valve feeding pipe assembly for realizing feeding without vacuum period. The electronic stop valve is installed on the feeding pipe with pump near the end of the material box, and is connected to the top of the material box through an auxiliary fixing assembly. After loosening the fixing bolt, the L-shaped mounting seat is moved horizontally at the top of the material box, and the clamping block is set on the electronic stop valve, thereby completing the limit of the electronic stop valve. At this time, the fixing bolt can be tightened. After the feeding pipe with pump works, it shakes and is transmitted to the electronic stop valve and the clamping block. The fine sand filled in the clamping block increases the counterweight. The shaking of the clamping block is transmitted to the connecting spring. When it is necessary to release the connection between the clamping block and the electronic stop valve, the clamping block is manually pressed, and the clamping block drives the fixed buckle connected to it to fall. The fixed buckle is limited by the wedge block, so that the clamping block slides in the direction away from the electronic stop valve, and the connecting spring bends in the direction away from the electronic stop valve. Then the electronic stop valve is disconnected from the two sets of auxiliary fixing assemblies. BRIEF DESCRIPTION OF THE DRAWINGS

[0035] The utility model discloses a feeding pipe assembly with a valve for realizing feeding without a vacuum period. An electronic stop valve 11 is installed near the end of a material box 1 with a pump feeding pipe 10. When the feeding pipe with a pump 10 is working, the plastic particles in the material box 1 are sent to the melting bin 2 of the injection molding machine by the feeding pipe with a pump 10. When the feeding pipe with a pump 10 stops working, the electronic stop valve 11 also stops working. After the electronic stop valve 11 is closed, the plastic particles in the feeding pipe with a pump 10 cannot fall back into the material box 1. The utility model provides a feeding pipe assembly with a valve for realizing feeding without a vacuum period. When the feeding pipe with a pump 10 stops working, the electronic stop valve 11 also stops working.
