Description

Technical Field

[0001] The utility model relates to the field of injection molds, in particular to a mold which can realize demoulding of inserts in multiple different directions at one time. Background Art

[0002] The injection molding process is a low-cost production method suitable for mass production. The process is to use a molding machine to inject molten material into the cavity of the mold. After the material cools, it forms a workpiece that matches the shape of the cavity.

[0003] When using molds for injection molding, you may encounter the following problems: Figure 1 The workpiece shown in the figure is characterized in that a plurality of holes distributed along the radial direction are opened on its outer circumference. In order to realize the injection molding of the workpiece, it is necessary to allow the ends of a plurality of insertion needles to enter the cavity to occupy positions, that is to say, the axes of these insertion needles are also distributed along different radial directions of a circle.

[0004] However, due to this special structure, these insertion needles cannot be set on the same slider to realize the core pulling action (otherwise they will get stuck). Therefore, a slider mechanism can only be designed for each insertion needle separately. This will make the internal structure of the entire mold extremely complicated, greatly increasing both production costs and maintenance costs, and the risk of problems will also increase accordingly.

[0005] Therefore, a method or device capable of solving the above problems is now needed. Summary of the invention

[0006] The utility model aims to solve the above-mentioned deficiencies in the prior art and proposes a mold with simple structure, ingenious design, reasonable layout and smooth movement, which can utilize a slider to drive multiple inserts with angles between each other to perform demoulding action.

[0007] The technical solution of the utility model is: a mold that can realize the demoulding of inserts in multiple different directions at one time, characterized in that: an inclined guide column 1 and a locking module 2 are arranged on the fixed mold plate of the mold, a locking inclined surface 3 is arranged on the locking module 2, and a slider 4 is slidably connected to the movable mold plate of the mold, and a guide groove matching the inclined guide column 1 is opened on the slider 4, and a driving inclined surface matching the locking inclined surface 3 is also arranged on the outer side of the slider 4.

[0008] An arc guide groove 5 is opened in the slider 4, and a plurality of movable blocks 6 are movably connected in the arc guide groove 5. A slider entry needle 7 is connected to the movable block 6. An upper cover 8 is arranged above the arc guide groove 5. The slider entry needle 7 extends out through the gap between the upper cover 8 and the arc guide groove 5. In the mold closing state, the end of the slider entry needle 7 passes through the entry needle channel opened on the movable mold core 9 and extends into the cavity to occupy a position. In the mold opening state, the front end of the slider entry needle 7 will not completely escape from the entry needle channel.

[0009] Compared with the prior art, the utility model has the following advantages:

[0010] This structural form of mold can realize demoulding of inserts in multiple different directions at one time. It has a simple structure, ingenious design and reasonable layout. It designs a special structure to address the various problems caused by the need to design an independent slider mechanism for each blind hole when traditional molds are used for injection molding of workpieces with multiple blind holes at angles to each other.

[0011] It utilizes a slider to drive multiple slider insertion needles, and all the slider insertion needles are connected to the slider through a movable block that can swing freely. In this way, when the slider drives the slider insertion needles to perform core pulling action, the movable block can make adaptive swing, so that all the insertion needles can be pulled out synchronously at the same time under the drive of the same slider. It greatly simplifies the structure of the mold that can realize the processing of such parts, reduces the design cost and maintenance cost, and at the same time, compared with traditional molds of this type, its reliability is also greatly improved.

[0012] At the same time, the manufacturing process of this mold is simple and the manufacturing cost is low. Therefore, it can be said that it has many advantages and is particularly suitable for promotion and application in this field. Its market prospect is very broad. BRIEF DESCRIPTION OF THE DRAWINGS

[0017] The specific implementation of the present utility model will be described below in conjunction with the accompanying drawings. Figures 1 to 4As shown: a mold that can realize multiple demoulding of inserts in different directions at one time, an inclined guide column 1 and a locking module 2 are arranged on the fixed mold plate of the mold, and a locking inclined surface 3 is arranged on the locking module 2. A slider 4 is slidably connected to the movable mold plate of the mold, and a guide groove matching the inclined guide column 1 is opened on the slider 4. At the same time, a driving inclined surface matching the locking inclined surface 3 is also arranged on the outer side of the slider 4.

[0018] An arc guide groove 5 is opened in the slider 4, and a plurality of movable blocks 6 are movably connected in the arc guide groove 5. A slider entry needle 7 is connected to the movable block 6. An upper cover 8 is arranged above the arc guide groove 5. The slider entry needle 7 extends out through the gap between the upper cover 8 and the arc guide groove 5. In the mold closing state, the end of the slider entry needle 7 passes through the entry needle channel opened on the movable mold core 9 and extends into the cavity to occupy a position. In the mold opening state, the front end of the slider entry needle 7 will not completely escape from the entry needle channel.

[0019] The working process of the mold that can realize multiple different directions of insert demoulding at one time in the embodiment of the utility model is as follows: in the mold closing state, the end of the slider needle 7 passes through the needle channel provided on the movable mold core 9, extends into the interior of the cavity and forms a placeholder, the molding machine injects molten material into the cavity, the material is cooled to form a product, and the positions corresponding to the ends of the slider needles 7 form the following Figure 1 As shown in the figure, there are multiple blind holes distributed along the radius of the workpiece.

[0020] When the mold is opened, the locking bevel 3 on the locking module 2 leaves the driving bevel outside the slider 4, and the slider 4 recovers the freedom to move in the horizontal direction. Under the action of the inclined guide column 1 and the guide groove, the slider 4 moves in the direction away from the cavity.

[0021] During the movement, the ends of all the slider needles 7 are pulled out from the formed workpiece (specifically, the blind hole of the workpiece). During the movement of the slider needles 7, the movable block 6 at the root thereof will swing adaptively with the movement of the slider needles 7. That is to say, the movement trajectory of each slider needle 7 is along a certain radial direction of the workpiece, and the movable block 6 swings accordingly.

[0022] After the mold is fully opened, the ends of all the slider needles 7 are pulled out from the workpiece, but they will not fall out of the needle channel on the movable mold core 9. In this way, when the mold is closed next time, all the slider needles 7 will still move in the opposite direction along the previous movement trajectory under the guidance of the needle channel, and be reinserted into the specific position of the cavity and occupy the space.
