Description

Technical Field

[0001] The utility model relates to the technical field of injection molds, and specifically relates to an injection mold with complete demolding. Background Art

[0002] Traditional injection molds usually include a first template and a second template. The first template includes a first injection cavity, and the second template includes a core and a second injection cavity. The second injection cavity includes a cavity shell, and a push rod is arranged inside the cavity shell. The push rod cooperates with a cylinder push-pull device at the rear end. When demolding is required, the cylinder is used to push the push rod forward to push out the product.

[0003] However, the existing technology relies solely on the push rod (ejector pin) to achieve ejection demolding, and the means is relatively single. There will still be a situation where the plastic product cannot be smoothly demolded due to adhesion to the mold surface, or the plastic product will be damaged due to tearing during the ejection demolding process.

[0004] Therefore, in view of this, research and improvement are carried out on the existing structural deficiencies, and an injection mold with complete demolding is proposed. Content of the Utility Model

[0005] The purpose of the utility model is to provide an injection mold with complete demolding to solve the problems raised in the above background art.

[0006] To achieve the above purpose, the utility model provides the following technical solution: an injection mold with complete demolding, including a material taking component. The material taking component includes a bracket, a quick-change head, a guide rail, elastic clamping pieces, a demolding agent tank, a material taking cylinder, a driving cylinder, and a trigger plate. A quick-change head is arranged on one side of the top of the "Z"-shaped structure of the bracket, and a guide rail is fixed in the inner notch of the "Z"-shaped structure of the bracket. Two groups of elastic clamping pieces are symmetrically arranged below the guide rail, and a demolding agent tank is clamped and cooperated between adjacent elastic clamping pieces. A material taking cylinder is fixed at the bottom of the "Z"-shaped structure of the bracket, and a driving cylinder is fixed on the other side of the top of the "Z"-shaped structure of the bracket. And a trigger plate is fixedly connected to the output end of the driving cylinder.

[0007] Further, the trigger plate is slidably matched with the guide rail in the inner notch of the bracket, and the trigger plate is in pressing cooperation with the pressing nozzle of the demolding agent tank.

[0008] Further, a panel is arranged on one side of the material taking component, and a hot runner plate is fixedly connected to the end of the panel.

[0009] Further, the hot runner plate is connected to an injection molding machine through a nozzle, and a guide sleeve is arranged inside the hot runner plate.

[0010] Further, a bottom plate is arranged on the other side of the material taking component, and a mold base is fixedly connected to the end of the bottom plate.

[0011] Furthermore, a cavity matching the hot runner plate is formed inside the mold base, and a guide pillar matching the guide bushing is fixed inside the mold base.

[0012] Furthermore, the middle part of the mold base is connected with an ejector plate through a hydraulic mechanism, an ejector pin is fixed at the end of the ejector plate, and a spring is sleeved outside the ejector pin.

[0013] Compared with the prior art, the utility model has the following beneficial effects:

[0014] 1. When the utility model is in use, the present application still uses the conventional technical means of the prior art, that is, the structural design of arranging an ejector pin in the mold base. During use, under the drive of the hydraulic mechanism, the ejector pin is located inside the mold cavity of the mold base to eject, assisting the demolding of the plastic product cooled and formed. However, different from the prior art, through the use of the material taking assembly, a demolding agent is pre-sprayed inside the mold cavity, so that the product can be smoothly demolded without tearing, reducing the generation of waste products.

[0015] 2. When the utility model is in use, the material taking assembly of the present application is connected with a three-axis truss through a quick-change head as an end effector. During use, the plastic product ejected from the mold cavity is taken out by the material taking cylinder at the bottom of the "Z"-shaped structure of the bracket, and the extrusion of the trigger plate at the output end of the driving cylinder on the nozzle of the demolding agent tank is triggered to evenly spray the demolding agent on the inner wall of the mold cavity, which helps the smooth demolding of the plastic product during continuous production, making the demolding of the plastic product more thorough. In addition, the demolding agent tank is fixed in the inner concave opening of the "Z"-shaped structure of the bracket through an elastic clip, which is convenient for the user to disassemble, replace and has stronger practicability.

A quick-change head 102 is arranged on one side of the top of the "Z"-shaped structure of the bracket 101, and a guide rail 103 is fixed in the inner notch of the "Z"-shaped structure of the bracket 101. Two groups of elastic clip pieces 104 are symmetrically arranged below the guide rail 103, and a release agent tank 105 is clamped and matched between adjacent elastic clip pieces 104. A material taking cylinder 106 is fixed at the bottom of the "Z"-shaped structure of the bracket 101, and a driving cylinder 107 is fixed on the other side of the top of the "Z"-shaped structure of the bracket 101. The output end of the driving cylinder 107 is fixedly connected with a trigger plate 108. The trigger plate 108 is slidably matched with the guide rail 103 in the inner notch of the bracket 101, and the trigger plate 108 is in pressing cooperation with the pressing nozzle of the release agent tank 105. The material taking assembly 1 of the present application is connected to the three-axis truss through the quick-change head 102 as an end effector. During use, the plastic product ejected from the mold cavity is taken out by the material taking cylinder 106 at the bottom of the "Z"-shaped structure of the bracket 101, and the trigger plate 108 at the output end of the driving cylinder 107 presses the nozzle of the release agent tank 105 to evenly spray the release agent on the inner wall of the mold cavity, which helps the smooth demolding of the plastic product during continuous production and makes the demolding of the plastic product more complete. In addition, the release agent tank 105 is fixed in the inner notch of the "Z"-shaped structure of the bracket 101 through the elastic clip pieces 104, which is convenient for the user to disassemble, install and replace the release agent tank 105, and has stronger practicability;

[0022] As Figures 1 to 2As shown in the figure, a panel 2 is provided on one side of the material taking assembly 1, and a hot runner plate 3 is fixedly connected to the end of the panel 2. The hot runner plate 3 is connected to an injection molding machine through a nozzle 4. A guide sleeve 5 is arranged inside the hot runner plate 3. A bottom plate 6 is provided on the other side of the material taking assembly 1, and a mold base 7 is fixedly connected to the end of the bottom plate 6.

An ejector pin 10 is fixed to the end of the ejector plate 9, and a spring 11 is sleeved outside the ejector pin 10. This application still uses the conventional technical means of the existing technology, that is, the structural design of arranging the ejector pin 10 inside the mold base 7. During use, under the drive of the hydraulic mechanism, the ejector pin 10 is ejected inside the mold cavity of the mold base 7 to assist in demolding the cooled and formed plastic product. However, different from the existing technology, through the use of the material taking assembly 1 in this application, a demolding agent is pre-sprayed inside the mold cavity, so that the product can be smoothly demolded without being torn, reducing the generation of waste products.

[0023] Working principle: When using this injection mold with complete demolding, this application still uses the conventional technical means of the existing technology, that is, the structural design of arranging the ejector pin 10 inside the mold base 7. During use, under the drive of the hydraulic mechanism, the ejector pin 10 is ejected inside the mold cavity of the mold base 7 to assist in demolding the cooled and formed plastic product. However, different from the existing technology, through the use of the material taking assembly 1 in this application, a demolding agent is pre-sprayed inside the mold cavity, so that the product can be smoothly demolded without being torn, reducing the generation of waste products. The material taking assembly 1 of this application is connected to a three-axis truss through a quick-change head 102 as an end effector. During use, the plastic product ejected inside the mold cavity is taken out by the material taking cylinder 106 at the bottom of the "Z" - shaped structure of the bracket 101, and the trigger plate 108 at the output end of the driving cylinder 107 squeezes the nozzle of the demolding agent tank 105, spraying the demolding agent evenly on the inner wall of the mold cavity, which helps the plastic product to be smoothly demolded during continuous production, making the demolding of the plastic product more complete. In addition, the demolding agent tank 105 is fixed in the inner concave opening of the "Z" - shaped structure of the bracket 101 through an elastic clip 104, which is convenient for users to disassemble, install and replace the demolding agent tank 105, and has stronger practicability.
