Description

Technical Field

[0001] The invention relates to the field of mold splitting and closing, in particular to the field of setting inserts in molds. Background Art

[0002] Insert molding is a method of placing a special-shaped material insert into a mold, injecting plastic after the mold is closed, and allowing the molten plastic and the insert to connect and become solid, thereby making an integrated molding method containing special-shaped materials. This method solves the problem that the mechanical properties of ordinary plastic parts are difficult to guarantee. How to ensure the reliable positioning of metal inserts, stable production, and the qualified rate of finished products has always been a difficulty in the design of this type of mold. Summary of the invention

[0003] The present invention aims to provide an insert installation device, which makes the insert easier to install and position, while increasing the stability of the insert in the cavity, avoiding the production of defective products due to unstable positioning of the insert, and at the same time improving the matching accuracy between the insert and the cavity, reducing burrs, thereby improving production efficiency and plastic part quality.

[0004] In order to achieve the above-mentioned purpose, the invention discloses a novel insert installation device, including an insert template and a spring block, wherein the spring block is detachably installed in the insert template, an insert installation groove is left between the spring block and the insert template, and a magnet is installed on the part of the spring block that fits with the insert installation groove. When the insert is inserted into the insert installation groove, the strong magnet adsorbs the inserted part of the insert and restricts the movement of the insert so that the insert cannot be deviated.

[0005] Furthermore, a spring mounting hole is provided in the inner part where the spring block and the insert template are fitted, and a spring block spring is installed in the spring mounting hole. One end of the spring block spring is connected to the spring block, and the other end of the spring block spring (6) is connected to the insert template. When the spring block is completely pressed into the insert template during mold closing, the spring block spring is in a compressed state.

[0006] Furthermore, a threaded hole is provided inside the spring block, a screw hole is provided on the insert template, a limiting stud is arranged in the screw hole and cooperates with the threaded hole on the spring block, and a certain distance is reserved between the stud head of the limiting stud and the screw hole.

[0007] Furthermore, the distance reserved between the stud head of the limiting stud and the screw hole is the distance that the spring block spring ejects the spring block out of the insert template.

[0008] Furthermore, the spring mounting hole is arranged close to the limiting stud.

[0009] Furthermore, the number of the spring mounting holes and springs is no less than 2 and they are evenly distributed in the spring block.

[0010] Furthermore, the number of the limiting stud, and the screw holes and threaded holes corresponding to the limiting stud is not less than 2.

[0011] Furthermore, the outer sides of the insert template and the spring block are inclined surfaces inclined inwards.

[0012] The beneficial effects of the present invention are as follows:

[0013] 1. By embedding magnets at the insert installation location, the insert can be adsorbed by the adsorption force of the magnet, thereby improving the stability of the insert installation and avoiding the hidden danger of producing defective products due to the offset of the insert.

[0014] 2. By using the spring to act on the spring block and setting the reserved distance of the stud, the spring block can be movably installed in the insert template, so that the insert can be installed more conveniently, while reducing the burrs of the plastic parts caused by the gap of the spring block and improving the product production quality.

[0022] In order to make the purpose, technical solutions and advantages of the present invention more clearly understood, the present invention is further described in detail below in conjunction with the accompanying drawings and embodiments; it should be understood that the specific embodiments described herein are only used to explain the present invention and are not intended to limit the present invention.

[0023] In this embodiment, only one installation method of the insert in the plastic part model is listed, but it should be known that the application of this device is not limited to this plastic part model, and other devices that apply the principle of this device should fall within the protection scope of this device.

[0024] like Figures 1 to 4The figure shows a novel insert installation device of the present invention, including an insert template 2, which also includes a spring block 1, the spring block 1 is detachably installed in the insert template 2, an insert installation groove 3 is left between the spring block 1 and the insert template 2, and a magnet 4 is installed on the part of the spring block 1 that fits with the insert installation groove 3. When the insert 5 is inserted into the insert installation groove 3, the strong magnet 4 absorbs the inserted part of the insert 5 and limits the movement of the insert 5 so that the insert 5 cannot be offset.

[0025] like Figure 5 As shown, the inner part where the spring block 1 fits with the insert template 2 is provided with a spring mounting hole 10, in which a spring block spring 6 is installed, one end of the spring block spring 6 is connected to the spring block 1, and the other end of the spring block spring 6 is connected to the insert template 2. When the spring block 1 is completely pressed into the insert template 2 during mold closing, the spring block spring 6 is in a compressed state.

[0026] like Figure 5 and Figure 6 As shown, a threaded hole 9 is provided inside the spring block 1, a screw hole 7 is provided on the insert template 2, a limiting stud 8 is arranged in the screw hole 7 and cooperates with the threaded hole 9 on the spring block 1, and a certain distance is reserved between the stud head of the limiting stud 8 and the screw hole 7.

[0027] The distance reserved between the stud head of the limiting stud 8 and the screw hole 7 is the distance for the spring block spring 7 to eject the spring block 1 out of the insert template 2. The spring mounting hole 10 is arranged close to the limiting stud 8.

[0028] The outer sides of the insert template 2 and the spring block 1 are inclined surfaces inclined inwards.

[0029] The working process of this device is as follows: when installing the insert 5, the spring block 1 is subjected to the pre-tightening force of the spring block spring 6, and at the same time, under the limiting action of the limiting stud 8, it partially protrudes from the insert template 2, and the insert installation groove 3 is exposed, which is convenient for the installation of the insert 5. The insert 5 is stably installed under the adsorption of the magnet 4.

[0030] Then the mold is closed, and the spring block 1 completely enters the insert template 2 under the extrusion of the inclined surface, and the spring block spring 6 continues to act. Due to the action of the spring block spring 6, the spring block 1 is close to the inclined surface, leaving less gap, reducing the burrs generated by the subsequent plastic parts. In this process, the insert cannot be deflected under the adsorption of the magnet 4, ensuring the stability of the insert 5. The spring block spring 6 is in a compressed state, and then the cast plastic part and the insert 5 are integrated.

[0031] Finally, during demoulding, since the plastic part and the insert 5 have been cooled to become a complete solid, the insert is separated from the adsorption of the magnet 4 under the ejection force of the injection molding machine, and the insert molding work is completed.
