Description

Mould for producing leather sheath with plug

Technical Field

The utility model relates to the technical field of mold, concretely relates to mould with interior slide.

Background

Among the prior art, the leather sheath of taking the stopper, for example, cell-phone protective housing, the consent is seted up to its bottom, and the supporting stopper that has, the consent aligns with the hole that charges of cell-phone, and when the cell-phone charges, extracts the stopper from the consent, supplies the joint that charges to insert. When the leather sheath with the plug is produced by using the mold, the mold core for producing the plug hole needs to be manually taken out, so that the leather sheath with the plug cannot realize automatic production, the production efficiency is high, the yield is low, the period is long, the manpower waste is serious, and the production safety factor is low.

SUMMERY OF THE UTILITY MODEL

The utility model solves the technical problem that: the production automation of the leather sheath with the plug is realized.

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

According to the technical scheme, the push block moves downwards to be matched with the lower mold core to form a lower half part structure of the cavity. Along with the descending inner position of the pushing block, the pushing block is translated towards the outer side direction of the pushing block under the matching of the first inclined surface and the second inclined surface, and the elastic resetting piece is pressed to accumulate elastic potential energy. And (3) carrying out up-and-down die assembly, forming a complete product cavity by the upper die core, the push block and the lower die core, carrying out injection molding, opening the die after the product is molded, enabling the push block to move upwards relative to the lower die core, pushing the product upwards, enabling the inwards moving position to move upwards along with the push block, releasing the elastic potential energy of the elastic reset piece, and enabling the inwards moving position to move towards the inner side direction of the push block, so as to realize transverse core pulling of the product plug hole. And after the inner slide block is completely separated from the product, the product on the push block is clamped by using the jig and taken away from the die.

The utility model discloses utilize ejector pad upward movement, shovel quick-witted motionless drives interior capable position inward movement, breaks away from the product completely, realizes transversely loosing core, later, and the product is takied away from to the tool, accomplishes the automation of whole production, improves production efficiency.

Detailed Description

The utility model provides a mould of production area stopper leather sheath, includes the last mould and the lower mould that set up from top to bottom, sets up the last mould benevolence in last mould and sets up the lower mould benevolence 10 in the lower mould to and the demolding mechanism of setting on the lower mould.

With reference to fig. 1 and 2, the demolding mechanism includes a pushing block 20, a pushing rod 21, a shovel 30, and an inner slide 40.

The push block 20 is connected with a push rod 21, the push rod penetrates through the lower die core 10 and the lower die and is connected with a power source, and the power source such as an air cylinder drives the push rod to move linearly.

The shoveling machine 30 is fixed on the lower die core 10, and a second inclined plane is arranged on the shoveling machine.

With reference to fig. 3 to 6, the inner slide 40 is mounted on the push block 20 through a pair of slide press blocks 42 fixed on the push block, the pair of slide press blocks are provided with sliding grooves, and the inner slide is slidably fitted in the sliding grooves. The bottom of the push block 20 is provided with an inner slide cavity 22 and a plug cavity, 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 preceding lateral wall in interior position chamber is close the stopper core, sets up the elasticity piece that resets with between the leading flank of interior position, and the trailing flank of interior position is first inclined plane 41, cooperates with the second inclined plane of shovel machine, and the space between the trailing flank of interior position and the trailing flank in interior position chamber supplies shovel machine 30 to insert.

In the practical operation, refer to fig. 3 to 6, when the mould is in the compound die state, ejector pad 20 cooperates with lower mould benevolence 10, constitutes the die cavity of product with last mould benevolence jointly, and shovel machine 30 inserts and establishes between the trailing flank of line position and the back lateral wall in line position chamber, and under the drive on shovel machine second inclined plane, line position 40 outwards stands out ejector pad 20. After the product is injection molded, the mold is opened, the push block 20 moves upwards under the drive of the push rod 21, the shovel machine is gradually drawn out from the space between the rear side surface of the inner moving position and the rear side wall of the inner moving position cavity, and the inner moving position 40 moves inwards under the action of the elastic reset piece to realize transverse core pulling. And then, a jig outside the die clamps the product on the push block, the product is taken away from the die, and the whole production process is automatically finished. Preferably, the leather sheath with the plug is a mobile phone protective shell. The shovel 30 and the inner slide 40 are matched with each other, so that the push block 20 and the lower mold core 10 can be effectively and stably positioned.
