Description

Technical Field

[0001] This utility model relates to the field of mold technology, specifically to a mold structure employing a deep-entry gate. Background Technology

[0002] An injection mold is a tool used for molding plastics. It injects molten plastic into a cavity of a specific shape, which then cools and solidifies to form a plastic product with the desired shape and size. Injection molds are widely used in many industries such as electronics, automobiles, home appliances, and daily necessities, and are a key piece of equipment for achieving large-scale production of plastic products.

[0003] In traditional injection mold design, sprue gates are typically designed as large inlets through which molten plastic enters the mold cavity. To ensure uniform filling, a large sprue size is often required, but this leads to additional material waste. In traditional mold designs, the plastic from the sprue area needs to be sheared off after injection molding, resulting in unnecessary raw material loss. Summary of the Invention

[0004] The purpose of this invention is to provide a mold structure with a deep-entry gate, in order to solve the problem mentioned in the background art that in traditional mold designs, the plastic at the gate needs to be cut off after injection molding, resulting in unnecessary raw material loss.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a mold structure with a deep-penetrating nozzle, comprising a mold body, a main channel formed within the mold body, a vertical flow channel connected to the middle of the main channel in the front-to-back direction, a horizontal flow channel connected to the main channel in the transverse direction, a first sinking groove formed within the vertical flow channel, a first nozzle connected to the bottom of the first sinking groove, a third sinking groove formed on both sides of the main channel, a second nozzle connected to the bottom of the third sinking groove, a second sinking groove formed within the main channel, a third nozzle connected to the bottom of the second sinking groove, a heat-conducting layer provided on the bottom surface of the main channel, a branched flow channel connected to the horizontal flow channel, and heating resistors provided on both sides of the first sinking groove.

[0006] As a further technical solution of this utility model, protective sleeves are fixed at the four corners of the mold body, and the protective sleeves are symmetrically distributed about the central axis of the mold body.

[0007] As a further technical solution of this utility model, the first sinking trough is distributed in three groups in the vertical flow channel, and the third sinking trough is symmetrically distributed about the central axis of the mold body.

[0008] As a further technical solution of this utility model, the transverse flow channel and the branch flow channel are interconnected, and the branch flow channels are symmetrically distributed about the central axis of the mold body.

[0009] As a further technical solution of this utility model, a water tank is provided inside the mold body below the heat-conducting layer, and a cooling water pipe is provided inside the water tank. The cooling water pipe has a meandering design.

[0010] As a further technical solution of this utility model, one end of the cooling water pipe is connected to a water inlet, and the other end of the cooling water pipe is connected to a water outlet.

[0011] As a further technical solution of this utility model, both the water outlet and the water inlet are connected to the cooling water pipe, and both the water outlet and the water inlet are equipped with valves.

[0012] As a further technical solution of this utility model, the outer wall of the mold body is coated with a wear-resistant layer, and a reinforcing component is provided in the solid area inside the mold body. The reinforcing component includes a first reinforcing rod and a reinforcing connecting block, and the reinforcing connecting block is connected between the first reinforcing rods.

[0013] Compared with the prior art, the beneficial effects of this utility model are: the mold structure with a deep-entry gate not only improves the reduction of waste, but also improves the cooling capacity and deformation resistance of the mold.

[0014] (1) After the main channel is arranged, the vertical flow channel is connected to the front and rear positions, and the horizontal flow channel is connected to the horizontal position. The first gate, the third gate and the second gate are respectively set at the bottom of the first sinking groove, the second sinking groove and the third sinking groove. By adopting the deep-entry gate design, the deep-entry gate adopts the gradient design to gradually guide the molten plastic into the mold cavity, avoid the excessive accumulation of material in the gate part, thereby reducing material waste, reducing the size of the gate, so that the molten plastic can flow into the mold cavity quickly and evenly during the injection process, while reducing the material consumption in the gate part. Furthermore, with the addition of the horizontal and vertical flow channels, the diameter, length and shape of the flow channels are reasonably arranged to ensure that the plastic melt can flow smoothly, while minimizing the material waste in the gate area.

[0015] (2) By opening a water tank inside the mold body and setting the water tank below the heat-conducting layer, and then arranging cooling water pipes in the water tank, the cooling water pipes are designed in a meandering shape. Therefore, after the cooling water enters at the water inlet, it flows along the cooling water pipes and is finally discharged at the water outlet. The heat is conducted by the heat-conducting layer, thereby improving the cooling capacity during operation, ensuring uniform cooling of the mold body, and avoiding local overheating or insufficient cooling caused by excessive water inlet or uneven material flow.

[0016] (3) By coating the wear-resistant layer on the outer wall of the mold body, the wear-resistant layer plays a wear-resistant protection role. Secondly, a reinforcing component is set in the solid area inside the mold body. The reinforcing component includes a first reinforcing rod and a reinforcing connecting block. After connecting the first reinforcing rod with the reinforcing connecting block, it has a certain strength, thereby reducing the overall deformation of the mold body. Attached Figure Description
