Description

Prevent scraping slider limit structure of colored product based on mould

Technical Field

The utility model relates to a mould field, concretely relates to prevent scraping slider limit structure of colored product based on mould.

Background

The mould is various moulds and tools for obtaining required products by injection molding, blow molding, extrusion, die casting or forging forming, smelting, stamping and other methods in industrial production. In short, a mold is a tool used to make a shaped article, the tool being made up of various parts, different molds being made up of different parts. The processing of the appearance of an article is realized mainly through the change of the physical state of a formed material. The element has the name of "industrial mother".

The slide block is a mold component which can slide in a direction perpendicular to the mold opening and closing direction or at a certain angle with the mold opening and closing direction during the mold opening action of the mold. When the product structure makes the mould in the mould opening direction, special mechanisms such as a slide block and the like are used under the condition that the mould cannot be normally demoulded. The material has proper hardness and wear resistance and is enough to bear the friction of movement. The cavity or core portion of the slide is of the same hardness as the remainder of the cavity core.

In a mold, a slide block and a ball head jackscrew are usually used in cooperation, and the ball head jackscrew is usually used for a small line position and a line position with a larger stroke in the X direction (horizontal direction). It can also help the slide delay die sinking because the wave beads will resist the slide and will not move when the side edge is not working. At this moment, the pressed ball head jackscrew can move downwards, and when the walking position finishes the stroke, the groove can be just at the wave bead top of the ball head jackscrew, and the wave bead can be upwards propped.

However, for the conventional sliding block, the sliding block is in clearance fit because the sliding block needs to reciprocate; in the process of die sinking and retreating, the sliding block can incline under the action of the elastic force of the ball head jackscrew, and the movement of the sliding block can be influenced to a certain extent. For a conventional sliding block, in the reciprocating motion process of the sliding block, a ball head jackscrew always has upward elastic force on the sliding block, the elastic force promotes the sliding block to move upwards, but because the two sides of the sliding block are limited by a sliding block pressing strip 1 and a sliding block pressing strip 2, the sliding block can only incline at a certain supporting point by utilizing a tolerance gap between workpieces, and when the sliding block is contacted with a product, the front end of the head of the sliding block can scratch the product in motion.

SUMMERY OF THE UTILITY MODEL

The utility model aims to solve the technical problem that in current mould, the slider can lead to the slider to scrape colored product when sliding in the distance of slider and product contact under the effect of bulb jackscrew, influences the availability factor, and aim at provides the slider limit structure who prevents scraping colored product based on the mould, solves the problem of slider fish tail product.

The utility model discloses a following technical scheme realizes:

the sliding block limiting structure of the anti-scratching product based on the die comprises a die body, wherein the die body comprises a traveling seat, a sliding block and a ball head jackscrew, the sliding block and the ball head jackscrew are arranged on the traveling seat, the distance between the positive pressure of the sliding block and the product is L1, an exit groove with the length of L2 is arranged right above the ball head jackscrew on the traveling seat, the exit groove and the sliding block slide out of the product in the mutually parallel direction, and L2 is greater than L1; when the sliding block exits the product, no pressure exists between the slide seat and the ball head jackscrew.

Furthermore, when the device is used, a section of abdicating groove is cut at the ball head jackscrew position of the slide seat, namely the abdicating groove, the length of the abdicating groove is L2, the length of L2 is greater than the length L1 of the slide block pressed right above the product, and when the device is used on the abdicating groove, no pressure exists between the ball head jackscrew and the abdicating seat, so that the structure ensures that the ball head jackscrew cannot be stressed in the idle stroke L2, and the slide block cannot be inclined due to the elasticity of the ball head jackscrew in the process of completely withdrawing the product.

Therefore, when the sliding block exits the product, the surface of the product cannot be scratched due to inclination, and the use efficiency can be further improved.

And the utility model discloses only increased one on original structure and moved out the groove, the processing degree of difficulty is less.

Simultaneously, owing to withdraw from the existence in groove, the slider of this structure also can not be in the tilt state always, therefore the slider of this structure can move more smoothly, steady. The slide block is not stressed and inclined in the process of withdrawing the product, so that the possibility that the slide block retreats to scratch the product is eliminated.

Specifically, based on the slider limit structure of the anti-scratch product of the mould, the width of the withdrawing groove is 1-2 mm more than the back-off of the product in the motion direction of the slider. The depth is set to be 1-2 mm higher than the ball head jackscrew, so that the slide block is not only effectively free of pressure between the slide seat and the ball head jackscrew when withdrawing from a product, and is more convenient to process and operate and use.

Preferably, the lower end of the ball head jackscrew is connected with a headless screw based on a slide block limiting structure of a scratch-resistant product of the die. The headless screw is used for fixing and placing, the using efficiency is further improved, and better supporting and using are achieved.

Preferably, the tail end of the exit groove of the sliding block limiting structure of the anti-scratching product is provided with an inclined plane and an arc, so that the ball head jackscrew can retreat conveniently. The tail end of the exit groove is provided with the inclined plane and the circular arc, so that when the ball head jackscrew moves in the exit groove, the ball head jackscrew can be effectively protected, and the service life is prolonged.

Compared with the prior art, the utility model, following advantage and beneficial effect have:

1. the utility model discloses based on the slider limit structure of the anti-scratching product of mould, this device can effectually avoid when the slider presses on the product, the slider withdraws from the product, causes the scratching to the product, further improves product quality and production efficiency;

2. the utility model discloses a slider limit structure of anti-scratch product based on mould, the device has simple structure, no complex operation, and is more convenient for long-term use;

3. the utility model discloses prevent scraping slider limit structure of colored product based on mould, the slider of this structure can not be in the tilt state always, and consequently the motion of the slider of this structure is more smooth and easy, steady, the operation of being more convenient for is used.
