Description

Mould for producing leather sheath with plug

Technical Field

The invention relates to the technical field of dies, in particular to a die with internal slide.

Background

In the prior art, a leather sheath with a plug, for example, a mobile phone protective shell, is provided with a plug hole at the bottom end, and is matched with the plug hole, the plug hole is aligned with a charging hole of a mobile phone, and when the mobile phone is charged, the plug is pulled out of the plug hole for the charging connector to be inserted. When the leather sheath with the plug is produced by using the die, the die core for producing the plug hole needs to be manually taken out, so that the leather sheath with the plug cannot be automatically produced, the production efficiency is low, the production yield is low, the period is long, the manpower waste is serious, and the production safety factor is low.

Disclosure of Invention

The technical problems solved by the invention are as follows: realizing the production automation of leather sheath with plug.

In order to solve the technical problems, the invention provides the following technical scheme: the utility model provides a production takes mould of stopper leather sheath, includes upper die and lower mould that sets up from top to bottom, sets up the last mould benevolence in the upper die and sets up the lower mould benevolence in the lower mould to and set up the demolding mechanism on the lower mould, demolding mechanism includes ejector pad, shovel machine, interior position, the ejector pad can go up and down relative lower mould benevolence, the shovel machine is installed on the lower mould benevolence, interior position movable mounting is on the ejector pad, is equipped with the elasticity piece that resets between interior position and the ejector pad, and interior position is equipped with first inclined plane, is equipped with on the shovel machine with first inclined plane complex second inclined plane.

According to the technical scheme, the pushing block descends and is matched with the lower die core to form the lower half part structure of the die cavity. And the elastic reset piece is pressed to accumulate elastic potential energy along with the descending inner position of the push block and translates to the outer side direction of the push block under the cooperation of the first inclined surface and the second inclined surface. And the upper die core, the push block and the lower die core form a complete product cavity, the product is molded, the die is opened after molding, the push block moves upwards relative to the lower die core to push up the product, the inner movement position moves upwards along with the push block, the elastic potential energy of the elastic resetting piece is released, and the inner movement position moves towards the inner side direction of the push block to realize the transverse core pulling of a plug hole of the product. And after the inner traveling block is completely separated from the product, the product on the pushing block is clamped by using the jig, and the product is taken away from the die.

According to the invention, the pushing block moves upwards, the shovel is not moved, the inner movement position is driven to move inwards, the product is completely separated from the shovel, the transverse core pulling is realized, and then the jig removes the product, so that the whole production automation is finished, and the production efficiency is improved.

Detailed Description

A mould for producing leather sheath with plug comprises an upper mould, a lower mould, an upper mould core, a lower mould core 10 and a mould stripping mechanism, wherein the upper mould and the lower mould are arranged up and down, the upper mould core is arranged in the upper mould, the lower mould core 10 is arranged in the lower mould, and the mould stripping mechanism is arranged on the lower mould.

Referring to fig. 1 and 2, the demolding mechanism includes a push block 20, a push rod 21, a shovel 30, and an inner row 40.

The pushing block 20 is connected with a pushing rod 21, the pushing rod passes through the lower die core 10 and the lower die and is connected with a power source, such as a cylinder, to drive the pushing rod to linearly move.

The shovel 30 is fixed on the lower die core 10, and is provided with a second inclined plane.

Referring to fig. 3 to 6, the inner slide 40 is mounted on the push block 20 by a pair of slide blocks 42, which are fixed on the push block and are provided with slide grooves in which the inner slide is slidably fitted. The bottom of the push block 20 is provided with an inner slide cavity 22 and a plug cavity, wherein the inner slide is matched in the inner slide cavity, and a plug core 43 on the inner slide is matched in the plug cavity; the front side wall of the inner slide cavity is close to the plug core, an elastic reset piece is arranged between the front side wall of the inner slide cavity and the front side surface of the inner slide, the rear side surface of the inner slide is a first inclined surface 41 which is matched with the second inclined surface of the shovel, and the shovel 30 is inserted into a space between the rear side surface of the inner slide and the rear side wall of the inner slide cavity.

In actual operation, referring to fig. 3 to 6, when the mold of the present invention is in a mold-closing state, the push block 20 cooperates with the lower mold core 10 to form a mold cavity of a product together with the upper mold core, the shovel 30 is inserted between the rear side surface of the inner slide and the rear side wall of the inner slide cavity, and the inner slide 40 protrudes outwards from the push block 20 under the driving of the shovel second inclined surface. After the product is injection molded, the mold is opened, the push block 20 is driven by the push rod 21 to move upwards, the shovel machine is gradually pulled out from between the rear side surface of the inner slide and the rear side wall of the inner slide cavity, and the inner slide 40 moves inwards under the action of the elastic reset piece, so that transverse core pulling is realized. Then, the product on the pushing block is clamped by the jig outside the die, and is taken away from the die, and the whole production process is automatically completed. Preferably, the leather sheath with the plug is a mobile phone protective shell. Wherein, the shovel 30 and the inner row 40 cooperate with each other to effectively and stably realize the positioning between the push block 20 and the lower die core 10.
