Description

Technical Field

[0001] The utility model relates to the technical field of injection molding machines, in particular to an injection molding machine with a self-cooling injection molding machine head. Background Art

[0002] Injection molding machine, also known as injection molding machine or injection machine, is the main molding equipment for making plastic products of various shapes from thermoplastics or thermosetting plastics using plastic molding molds. It is divided into vertical, horizontal and all-electric types. The injection molding machine can heat the plastic and apply high pressure to the molten plastic to make it eject and fill the mold cavity. It is the main molding equipment for making plastic products of various shapes from thermoplastics or thermosetting materials using plastic molding molds. It is a common processing device. The working principle of the injection molding machine is similar to that of a syringe for injections. It uses the thrust of the screw to inject the plasticized molten plastic into the closed mold cavity, and obtains the product after solidification and shaping.

[0003] Today's injection molding machines can basically meet people's needs, but there are still some problems. The specific problems are as follows:

[0004] 1. The problem of difficulty in replacing molds of injection molding machines. When processing different items, it is necessary to replace molds of different models. Traditional injection molding machine molds are difficult to replace, the processing is not flexible enough, and cannot adapt to different processing conditions.

[0005] 2. The injection molding machine has difficulty cooling the injection molding nozzle. When the injection molding nozzle is injecting, the temperature of the injection molding nozzle will be high due to processing, and it is difficult for the injection molding nozzle to dissipate heat quickly. Utility Model Content

[0006] The utility model aims to provide an injection molding machine with a self-cooling injection molding machine head, so as to solve the defects of the existing injection molding machine that it is difficult to replace the mold and difficult to cool the injection molding nozzle.

[0011] When in use, the melted material can be first loaded into the shell, and the hydraulic cylinder can drive the top plate, the mounting frame and the injection nozzle to rise and fall. When the mounting frame descends, the pressure plate is pressed on the top of the mold. Since the second guide rod can slide inside the first guide rod, the first guide rod and the second guide rod can guide the pressure plate. After the pressure plate is pressed on the top of the mold, the injection nozzle will also descend, and the injection nozzle will be inserted into the round hole on the pressure block. Then the discharge pump can work to guide the material inside the shell through the conduit, and then the material is injected into the mold through the injection nozzle for forming processing. When the injection nozzle and the mounting frame rise, the elasticity of the first spring inside the first guide rod will drive the pressure plate to reset.

[0012] Furthermore, a card slot is provided inside the mounting block, and a card block is provided at the bottom end of the mold. The mounting block and the mold form a card-fitting structure, and the card-fitting structure is easy to disassemble.

[0013] Furthermore, a guide structure is installed at the top end of the pressure plate, and the guide structure includes a first guide rod, a second guide rod and a first spring. The first guide rod is installed at the bottom end of the mounting frame, and a first spring is installed inside the first guide rod.

[0016] Furthermore, a groove is provided at one end of the heat sink, and the grooves are arranged at equal intervals on one side of the heat sink, so that the grooves can increase the surface area of ​​the heat sink.

[0017] Furthermore, a buckle is installed on one side of the movable plate, and the buckle is symmetrically distributed about the central axis of the mounting block, and the buckle can be snapped into the interior of the mold.

[0018] The injection molding machine with a self-cooling injection molding head provided by the utility model has the advantages that: a mold is movably connected to the top of the mounting block, and the mold and the mounting block form a clamping structure, so that the mold can be clamped into the mounting block for installation. After the mold is clamped into the mounting block, the buckle can be clamped into the mold, and the buckle will fix the mold. The movable plate and the baffle on one side of the buckle are connected by a second spring, and the elasticity of the second spring will drive the buckle to clamp into the mold. When the mold needs to be replaced, the buckle can be pulled open so that the buckle is no longer stuck in the mold, and the mold can be replaced, thereby achieving the purpose of facilitating mold replacement of the injection molding machine.

[0019] By installing a heat conducting plate on the outside of the injection molding nozzle, the heat conducting plate and the heat sink can be made of brass material or other metal material with good thermal conductivity. When the temperature of the injection molding nozzle is too high, the temperature of the injection molding nozzle will be absorbed by the heat conducting plate. The absorbed heat conducting plate can dissipate the heat through the heat sink. The heat sink has a large surface area and can dissipate heat quickly, thereby achieving the purpose of the injection molding machine facilitating rapid heat dissipation of the injection molding nozzle.
