Description

Technical Field

[0001] The utility model belongs to the technical field of injection molds, and particularly relates to a precise positioning injection mold for parts. Background Art

[0002] Injection molding, also known as injection molding, is a molding method that combines injection and molding. The advantages of injection molding are fast production speed, high efficiency, automated operation, a wide variety of colors, shapes from simple to complex, sizes from large to small, and precise product size. The product is easy to update and can be made into complex-shaped parts. Injection molding is suitable for mass production and complex-shaped products and other molding and processing fields.

[0003] At present, when the existing injection molds are in use, the equipment is prone to insufficient support or limiting strength during long-term operation, resulting in device operation failure or even jamming. The positioning is not accurate enough, which has a great impact on the safety of the staff. Utility Model Content

[0004] The utility model aims to provide a precise positioning injection mold for parts, which solves the problem of inaccurate positioning of existing injection molding equipment.

[0005] In order to solve the above technical problems, the utility model is achieved through the following technical solutions:

[0006] The utility model is a precise positioning injection mold for parts, comprising a base plate and a first baffle and a second baffle arranged on the outer walls at both ends of the top of the base plate, a transverse axis is arranged between the inner walls at opposite ends of the first baffle and the second baffle, and a clamping plate is slidably sleeved on the circumferential outer wall of the transverse axis, a fixing plate is fixedly installed on the top outer wall of the second baffle, and a driving motor is arranged on the outer wall at one end of the fixing plate, a threaded rod is connected to one end of the output shaft of the driving motor, and the clamping plate is sleeved on the circumferential outer wall of the threaded rod through a thread, molding grooves are formed on the outer walls on both sides of one end of the clamping plate, and molding plates matched with the molding grooves are arranged on the outer walls on both sides of the other end of the fixing plate, a feeding mechanism for pouring raw materials into the molding groove is arranged on the top outer wall of the other end of the clamping plate, and an ejection mechanism for automatic discharge is arranged between the outer walls at both ends of the clamping plate.

[0007] Furthermore, the feeding mechanism includes a distribution pipe, and the distribution pipe is arranged on the top outer wall of the other end of the clamping plate, the inner wall of one end of the forming groove is provided with a feeding hole connected to the distribution pipe, and the top outer wall of the other end of the distribution pipe is provided with a feeding pipe, and the inner walls on both sides of the distribution pipe are provided with control valves.

[0008] Furthermore, both outer walls on both sides of the top end of the clamping plate are provided with limiting rods, and both outer walls on both ends of the top of the fixing plate are provided with limiting holes matched with the limiting rods.

[0009] Furthermore, the ejection mechanism includes two ejection rods, and the ejection rods are respectively inserted into the inner wall of one end of the forming groove, a movable plate is arranged between the outer walls of the other end of the ejection rod, and the outer walls on both sides of one end of the movable plate are provided with extrusion rods inserted between the outer walls at both ends of the card plate, and a plurality of return springs sleeved on the circumferential outer wall of the extrusion rod are arranged between the inner walls of the opposite end of the card plate and the movable plate.

[0010] Furthermore, a limiting plate is provided on the outer wall of one end of the extrusion rod.

[0011] Furthermore, indicators are provided on the outer walls on both sides of the other end of the distribution pipe, and side plates are provided on the top outer walls on both sides of the movable plate, and position sensors compatible with the indicators are provided on the outer walls of one end of the side plates, and the position sensor is electrically connected to the control valve.

[0012] Furthermore, multiple clamping plates are provided on both outer walls of the top of the bottom plate, and multiple rotating rods are rotatably connected between the inner walls of the opposite ends of the clamping plates through bearings, and the circumferential outer walls of the rotating rods are sleeved with rotating belts.

[0013] The utility model has the following beneficial effects:

[0014] 1. The utility model uses a card plate and a fixed plate. When injection molding is performed, the driving motor will make the card plate gradually approach the fixed plate under the action of the threaded rod, and make the molding plate fit into the molding groove. At this time, the hot fluid plastic will enter the distribution pipe through the feed pipe, and enter the two molding grooves through the feed holes for cooling and molding, thereby achieving a rapid injection molding effect. In addition, during the injection molding process, the horizontal axis and multiple limit rods will provide stable support and limiting effects for the moving card plate, so that the card plate and the fixed plate can be accurately positioned, and the practicality and stability are stronger.

[0015] 2. The utility model uses a movable plate. When the card plate is moving and contacts the fixed plate, the extrusion rod will contact the fixed plate in advance, and the entire movable plate will pull the reset spring away from the card plate. At this time, the discharge rod will be exactly in the same plane with the inner wall of the molding groove. When the injection molding is completed and the card plate is separated from the fixed plate, the movable plate will be close to the card plate again under the action of the reset spring, and the molded mold will be pushed out of the molding groove by the discharge rod, achieving the effect of rapid demoulding. When the card plate contacts the fixed plate, when the position sensor and the indicator are at a certain distance, the control valve in the distribution pipe is opened, thereby achieving the effect of automatic filling, which is more convenient to use.

[0016] 3. The utility model provides a clamping plate and a rotating belt, so that when the device is demoulding, the fallen mold will directly roll out of the contact position between the clamping plate and the fixed plate to prevent the device from getting stuck.

[0017] Of course, any product implementing the present invention does not necessarily need to achieve all of the advantages described above at the same time. BRIEF DESCRIPTION OF THE DRAWINGS
