Description

Technical Field

[0001] This utility model relates to the field of injection mold technology, specifically to an injection mold that can improve the bearing capacity of the slider. Background Technology

[0002] In injection molding, the structural design of the injection mold plays a crucial role in product quality and production efficiency. The slider, as a key component in the mold that enables lateral core pulling, often faces numerous challenges. With the increasing diversity and complexity of plastic products, product designs often include various lateral holes, undercuts, and complex contour features. This necessitates that the slider in the injection mold withstand high-pressure lateral forces from the molten plastic during the injection process.

[0003] The slider in the injection mold needs to withstand the high pressure lateral force from the plastic melt during the injection process. However, in the existing injection mold production, due to the rise in mold temperature, the small pressure block of the slider is subjected to uneven force under the mold closing pressure of the heated mold, resulting in unsmooth operation. Utility Model Content

[0004] The purpose of this invention is to provide an injection mold that can improve the bearing capacity of the slider, has the advantages of smooth sliding of the internal slider and no longer jamming abnormalities, and solves the problem that the slider mechanism of the current injection mold is prone to jamming, resulting in uneven production.

[0005] To achieve the above objectives, this utility model provides the following technical solution: an injection mold that can improve the bearing capacity of a slider, including a driving mechanism, a lifting mechanism slidably mounted on the top of the driving mechanism, a mold mechanism provided between the driving mechanism and the lifting mechanism, the mold mechanism including a lower mold, an upper mold provided on the top of the lower mold, the top of the upper mold being fixedly connected to the bottom of the lifting mechanism, and two positioning plates symmetrically arranged on the side of the upper mold, two positioning blocks symmetrically slidably mounted on the top of the lower mold facing the positioning plates, and two sliding mechanisms symmetrically arranged on the lower mold.

[0006] Preferably, the driving mechanism includes a base, and a plurality of lead screws for driving the lifting mechanism to rise and fall are symmetrically arranged at the top of the base.

[0007] Preferably, the lifting mechanism includes a top plate, and a plurality of limiting plates are symmetrically arranged on the side of the top plate, and the bottom end of the side of each limiting plate is connected to the side of the driving mechanism.

[0008] Preferably, each of the upper molds has an arc surface on one side near the positioning block, and each of the positioning blocks has a positioning groove on the side facing the upper mold for the positioning plate to fit into.

[0009] Preferably, each of the sliding mechanisms includes an inclined plate, which is inclined toward the lower mold, and an arc block is provided at the top of the side of the inclined plate away from the lower mold, and an arc surface is provided on the side of the arc block away from the lower mold.

[0010] Preferably, the bottom end of the inclined plate is provided with a slider, one end of which is flush with the side of the inclined plate opposite the arc block, and the other end extends out of the other side of the inclined plate. The bottom end of the slider is provided with a convex plate, and the end of the slider is provided with a horizontal hole. Both sides of the convex plate extend out of the side of the slider, and the bottom end of the convex plate is provided with a vertical hole that connects to the horizontal hole.

[0011] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0012] 1. This utility model sets up an inclined plate, a slider and a convex plate. The slider is set at the bottom of the inclined plate and supported by the convex plate at the bottom of the slider. The two sides of the convex plate extend out of the sides of the slider, making the original small pressure block into a large pressure block. The original design of the inner slider pressure block is changed to a pressure block with a larger force-bearing area, so that the sliding is smooth and the problem of uneven force and unsmooth operation is easily improved.

[0013] 2. This utility model, by setting an upper mold, positioning plate, positioning block and positioning groove, can position the upper mold by embedding the positioning plate set on both sides of the upper mold into the positioning groove opened in the positioning block, and is used to control the thickness of the injection molded part. The arc surface set at the end of the positioning plate can guide the positioning plate when it is embedded in the positioning groove opened in the positioning block, so as to avoid the problem of inconsistent thickness of batches of injection molded parts.
