Description

TECHNICAL FIELD

[0001] The present disclosure relates to the technical field of mold devices, in particular to a mold device facilitating material withdrawal. BACKGROUND

[0002] A mold device is a processing device for making a material into a desired shape of a part or product through pressure. Mold devices are widely used in the fields of hardware products, automobile parts, toy products, electronic products, medical devices, and aerospace, etc.

[0003] A mold device in the related art comprises a mold base body and a material withdrawal mechanism. The mold base body is provided with a forming cavity for forming a product. The material withdrawal mechanism is installed on the mold base body. The material withdrawal mechanism is provided with a material withdrawal assembly and a spring. The material withdrawal assembly is elastically connected with the spring. Part of the material withdrawal assembly is located in the forming cavity. During the compression process of the mold device, the material withdrawal assembly compresses the spring. During the return and material withdrawal process of the mold device, the spring rebounds to drive the material withdrawal assembly to move, so that the material withdrawal assembly ejects the product, and the material withdrawal process is completed. For example, a Chinese patent with the patent number CN216096081U.

[0004] However, since the spring rebounds to drive the material withdrawal assembly to move to eject the product out of the forming cavity, the spring is switched between the compressed state and the stretched state for a long time during the long-time use of the mold device. Therefore, the spring is prone to failure during the long-time use. The failure of the spring leads to poor material withdrawal effect of the material withdrawal assembly on the product, thereby leading to poor material withdrawal effect of the mold device on the product. UTILITY MODEL CONTENT

[0005] The purpose of the present disclosure is to overcome the deficiencies in the prior art and provide a mold device facilitating material withdrawal with good material withdrawal effect on a product.

[0006] The purpose of the present disclosure is achieved by the following technical solutions:

[0007] A mold device facilitating material withdrawal comprises:

[0008] A first mold base body is provided with a mounting cavity and a connecting channel. The mounting cavity is in communication with the connecting channel.

[0009] A material withdrawal assembly comprises a material withdrawal driving member and a material withdrawal part. The material withdrawal driving member is located in the mounting cavity and connected with the first mold base body. A power shaft of the material withdrawal driving member extends into the connecting channel and slides in extension and retraction relative to the first mold base body. The material withdrawal part is located in the connecting channel. The power shaft of the material withdrawal driving member is connected with the material withdrawal part. The material withdrawal driving member is used to drive the material withdrawal part to move in the vertical direction, so that the material withdrawal part slides in the connecting channel relative to the first mold base body.

[0010] A second mold base body is detachably connected with the first mold base body, the second mold base body is provided with a cavity for forming a product, the cavity is communicated with the connecting channel, and the material returning driving element is used to drive the material returning part to extend into the cavity to push out the product.

[0011] In one of the embodiments, the material returning driving element is a driving motor, and the material returning driving element is electrically connected with an external power source.

[0012] In one of the embodiments, the first mold base body is further provided with an inflation channel, the inflation channel is communicated with the mounting cavity, and the inflation channel is used to guide the gas.

[0013] In one of the embodiments, the material returning driving element is a driving cylinder, and the gas inlet end of the material returning driving element is communicated with the inflation channel.

[0014] In one of the embodiments, the first mold base body is oppositely arranged with the second mold base body, and the first mold base body is located below the second mold base body.

[0015] In one of the embodiments, the first mold base body is provided with a connecting guide column, the second mold base body is further provided with a sliding guide groove, the connecting guide column is arranged in the sliding guide groove and is slidably connected with the second mold base body.

[0016] In one of the embodiments, the material returning part is an integrally formed structure.

[0017] In one of the embodiments, the material returning part is in a parallelogram shape, a triangular shape or a trapezoidal shape.

[0018] In one of the embodiments, the first mold base body is an integrally formed structure.

[0019] In one of the embodiments, the second mold base body is an integrally formed structure.

[0020] Compared with the prior art, the present disclosure has at least the following advantages:

[0021] 1. Since the power shaft of the material returning driving element extends into the connecting channel and is telescopically slid relative to the first mold base body, the power shaft of the material returning driving element is connected with the material returning part, so that the power shaft of the material returning driving element is used to drive the material returning part to slide in the connecting channel in the vertical direction, i.e. the material returning driving element is used to drive the material returning part to move in the vertical direction, so that the material returning part slides in the connecting channel relative to the first mold base body, the cavity is communicated with the connecting channel, the material returning driving element is used to drive the material returning part to extend into the cavity to push out the product, and the material returning process of the product is completed.

[0022] 2. Since the ejector drive is used to drive the ejector section into the cavity to eject the product, thereby separating the product from the cavity, in the long-term use of the mold device that facilitates ejection, the ejector drive replaces the spring in the prior art. The ejector drive is a drive motor or drive cylinder, which makes it less prone to failure during long-term use. This makes the ejector drive structurally more stable than the spring in the prior art, thus avoiding the problem of the spring switching back and forth between the compression and tension states for a long time. This solves the problem of the spring being prone to failure during long-term use, and further solves the problem of the poor ejection effect of the ejector assembly due to spring failure. As a result, the ejector section performs better ejection of the product under the action of the ejector drive, thus making the mold device that facilitates ejection perform better in ejecting the product.

The ejection assembly 200 includes an ejection drive 210 and an ejection part 220. The ejection drive 210 is located in the installation cavity 110 and connected to the first mold base 100. The power shaft of the ejection drive 210 extends into the connecting channel 120 and slides telescopically relative to the first mold base 100. The ejection part 220 is located in... Within the connecting channel 120, the power shaft of the ejector drive 210 is connected to the ejector part 220. The ejector drive 210 is used to drive the ejector part 220 to move in the vertical direction so that the ejector part 220 slides relative to the first mold base 100 within the connecting channel 120. The second mold base 300 is detachably connected to the first mold base 100. The second mold base 300 has a cavity 310 for molding the product 20. The cavity 310 communicates with the connecting channel 120. The ejector drive 210 is used to drive the ejector part 220 to extend into the cavity 310 to eject the product 20.

[0032] In this embodiment, the power shaft of the ejector drive 210 extends into the connecting channel 120 and slides telescopically relative to the first mold base 100. The power shaft of the ejector drive 210 is connected to the ejector part 220 so that the power shaft of the ejector drive 210 is used to drive the ejector part 220 to slide vertically in the connecting channel 120. That is, the ejector drive 210 is used to drive the ejector part 220 to move vertically so that the ejector part 220 slides relative to the first mold base 100 in the connecting channel 120.
