Description

Technical Field

[0001] This utility model relates to a material suitable for shell processing, and more specifically to an injection mold, specifically an injection mold for shell processing. Background Technology

[0002] Plastic casings are an indispensable part of modern electronic products and consumer goods. Their lightweight, durable, and low-cost characteristics make them widely used in various fields, such as mobile phones, home appliances, and automotive parts.

[0003] Plastic molds are tools used to process and shape plastic products, enabling mass production by giving plastic specific shapes and precise dimensions. They are widely used in the automotive, home appliance, and electronics industries. Their core structure includes a moving mold, a fixed mold, and systems for gating, temperature control, and ejection. Molding processes are classified into six categories: injection molding, compression molding, extrusion, blow molding, vacuum forming, and high-density polystyrene molding.

[0004] Molds are made from different materials depending on the process: injection molds are suitable for complex thermoplastic products, compression molds are mostly used for thermosetting plastics, and extrusion molds are used to produce continuous profiles such as pipes. Mold materials need to be heat-resistant, wear-resistant, and highly polishable. Carbon tool steel or alloy steel are commonly used, while corrosion-resistant steels such as martensitic stainless steel are used for corrosive plastics (such as PVC and ABS).

[0005] A typical plastic mold consists of two parts: a moving mold and a fixed mold. The moving mold is mounted on the moving platen of the injection molding machine, and the fixed mold is mounted on the fixed platen. During injection molding, the moving mold and the fixed mold close to form the gating system and the cavity. When the mold opens, the moving mold and the fixed mold separate to remove the plastic product.

[0006] Although the structure of a mold can vary greatly due to differences in the type and properties of the plastic, the shape and structure of the plastic product, and the type of injection molding machine, the basic structure remains the same. A mold mainly consists of a gating system, a temperature control system, molding parts, and structural parts. Among these, the gating system and molding parts are the parts that directly contact the plastic and vary depending on the plastic and the product; they are the most complex, the most variable, and require the highest level of surface finish and precision in the mold.

[0007] However, existing injection molds are not convenient for adjusting the thickness of the internal injection shell during use. Different molds are required to adjust the thickness, which is troublesome and inconvenient. In addition, existing molds consist of two parts, a moving mold and a fixed mold, which makes it inconvenient for material cutting. Utility Model Content

[0011] Furthermore, a limiting groove is provided on the base plate, and a limiting block is fixedly provided at the lower part of the moving head, with the limiting block sliding inside the limiting groove.

[0012] Furthermore, support rollers are movably installed on both sides of the connecting rod, and the connecting ring is movably installed between the two support rollers.

[0013] Furthermore, the servo electric cylinder is provided with a mounting frame on its outer side, and the mounting frame is fixedly mounted on the base plate.

[0014] Furthermore, guide rods are fixedly installed at the four corners of the upper surface of the base plate, and several support rings are sleeved on the bottom of the guide rods.

[0015] Furthermore, the middle plate has a first guide hole at each of its four corners, and the upper plate has a second guide hole at each of its four corners. The guide rod is movably positioned inside the first guide hole and the second guide hole, and the middle plate is fitted to the upper part of the support ring.

[0016] Furthermore, a connecting plate is fixedly provided on the lower surface of the sealing plate and the insertion frame, and the connecting cylinders on both sides are respectively fixedly provided on the lower surface of the connecting plate.

[0017] Furthermore, the middle plate has an injection cavity in the middle, and the bottom of the middle plate has an insertion groove on the outside of the injection cavity.

[0053] The specific operational procedures for this application are as follows:

[0054] In use, according to the thickness of the middle plate 2, several support rings 5 ​​are sleeved on the guide rod 4. Then, the middle plate 2 is installed with the guide rod 4 through the first guide hole 8, so that the sealing plate 607 is positioned inside the injection cavity 9, and the insertion frame 606 is precisely inserted into the insertion slot 10 to maintain precise alignment.

[0055] Then, according to the thickness requirements of the injection-molded shell, the adjustment mechanism 6 is driven and adjusted, that is, the servo cylinder 601 is driven so that the servo cylinder 601 can push and pull the moving head 602. The moving head 602 can maintain the stability of the movement adjustment through the cooperation of the limiting slide 603 and the limiting block 615. When the moving head 602 is pushed to the front end, the moving head 602 pulls the connecting rod 611 inward through the first crank rods 604 on both sides, so that the connecting plate 605, the insertion frame 606 and the sealing plate 607 can realize As the moving head 602 is pulled to the rear, it pushes the connecting rod 611 outward via the first crank rods 604 on both sides, allowing the connecting plate 605, insertion frame 606, and sealing plate 607 to rise. In other words, the connecting plate 605, insertion frame 606, and sealing plate 607 are connected to the connecting rod 611 at the bottom via the second crank rods 610 on both sides of the connecting cylinder 609, so that the first crank rod 604 can convert the lateral power into vertical power and control the lifting and lowering adjustment of the connecting plate 605, insertion frame 606, and sealing plate 607.

[0056] Finally, after adjusting the thickness of the injection-molded shell, the injection material is injected through the injection tube 7, so that the injection material can flow into the injection tank 608, which facilitates the injection molding of the shell.
