Abstract
The utility model discloses an injection mold's oblique top mechanism, including movable mould board, oblique ejector pin, thimble board and universal slide, its characteristics are: the outer wall of the oblique ejector rod is provided with two concentric guide sleeves which are separated by a spacer sleeve; be equipped with the mounting groove on the universal slide, the installation inslot activity is provided with the installed part, and oblique ejector pin is installed on the installed part, is equipped with arc positioning groove in the mounting groove on the relative both sides wall, is equipped with opening type self-lubricating shaft sleeve in the arc positioning groove, is equipped with the slide-shaft in the opening type self-lubricating shaft sleeve, is provided with the locating hole on the slide-shaft, is equipped with on the installed part to arrange in the locating hole and can. The utility model arranges two concentric guide sleeves on the outer wall of the oblique ejector rod, which is convenient for maintenance and replacement, and the two guide sleeves are separated by the spacer sleeve, so that the concentricity of the oblique ejector rod is higher; due to the self-lubricating type of the open type self-lubricating shaft sleeve, the abrasion of the sliding shaft and the open type self-lubricating shaft sleeve can be greatly reduced, and the phenomenon that the universal sliding seat is blocked is avoided.
Description
Technical Field
The utility model belongs to the technical field of injection mold, especially, relate to an injection mold's oblique top mechanism.
Background
The injection mold is adopted to produce plastic products, such as automotive upholsteries and the like, the back of the products is generally provided with an assembly fixing plate, a positioning buckle and the like, and an inverse buckle is formed between the back of the products and a product body, so that the inverse buckle at the position is generally demoulded by adopting an inclined ejection mechanism during mold design. In traditional mould course of working, the oblique ejector pin of pushing up the mechanism to one side generally directly passes the movable mould board and connects oblique top slider, perhaps installs a copper sheathing between oblique ejector pin and movable mould board, reduces the friction, and its shortcoming is: the inclined ejector rod has poor precision and low concentricity, and particularly a relatively large inclined ejector block is easy to shake and damage a product in the inclined ejection process; secondly, the standardization requirement is low, the specifications of the copper sleeves are different, some copper sleeves are machined by themselves, and the maintenance and the replacement are inconvenient.
At present, the fixing of oblique ejector pin is on the installed part of universal slide, connects on the installed part on the gleitbretter, gleitbretter and universal slide sliding connection, because gleitbretter and universal slide area of contact are little, and the atress is big to produce gleitbretter or universal slide wearing and tearing and then cause the phenomenon such as card death.
Disclosure of Invention
The utility model aims at providing an injection mold's oblique top mechanism to the not enough of above-mentioned prior art existence.
The utility model adopts the technical proposal that: an inclined ejection mechanism of an injection mold comprises a movable template, an inclined ejector rod, an ejector plate below the movable template and a universal sliding seat arranged on the ejector plate, wherein the movable template is provided with an inner hole into which the front part of the inclined ejector rod can extend, and the tail part of the inclined ejector rod is arranged on the universal sliding seat of the injection mold; the outer wall of the oblique ejector rod is provided with two concentric guide sleeves which are separated by a spacer sleeve; the universal slide is provided with a mounting groove, the mounting groove is internally and movably provided with a mounting part, the oblique ejector rod is mounted on the mounting part, arc positioning grooves are formed in two opposite side walls in the mounting groove, opening type self-lubricating shaft sleeves are arranged in the arc positioning grooves, sliding shafts are arranged in the opening type self-lubricating shaft sleeves, positioning holes are formed in the sliding shafts, and positioning protrusions which are arranged in the positioning holes and can move are arranged on the mounting part.
The two concentric guide sleeves are fixed by clamp springs.
After the structure is adopted, compared with the prior art, the utility model the advantage that has is: the utility model discloses set up two concentric guide pin bushings at the outer wall of oblique ejector pin, namely set up two concentric guide pin bushings between oblique ejector pin and movable mould board, the guide pin bushing adopts the standardized design requirement, there is standard component to sell on the market, it is convenient to maintain, change, keep apart by the spacer between two guide pin bushings, make the concentricity of oblique ejector pin higher, the oblique top precision is better, improve product quality; the oblique ejector pin is at the motion in-process, and the sliding shaft makes a round trip at opening type self-lubricating axle sleeve interdynamic, because the self-lubricating type of opening type self-lubricating axle sleeve, the wearing and tearing of reduction sliding shaft and opening type self-lubricating axle sleeve that can be very big avoid the emergence of universal slide card dead phenomenon.

Detailed Description
The following description is only for the preferred embodiment of the present invention, and the protection scope of the present invention is not limited thereby, the present invention will be further explained with reference to the drawings and the embodiments.
Examples, see fig. 1-4: the utility model provides an injection mold's oblique top mechanism, includes ejector plate 3 under movable mould board 1, oblique ejector pin 2, the movable mould board 1 and installs universal slide 4 on ejector plate 3, movable mould board 1 has seted up and has supplied the hole that 2 front portions of oblique ejector pin stretch into, the afterbody of oblique ejector pin 2 set up in on injection mold's universal slide 4.
The outer wall of the oblique ejector rod 2 is provided with two concentric guide sleeves 5, and the two guide sleeves 5 are separated by a spacer 6. Set up two concentric guide pin bushings 5 at the outer wall of oblique ejector pin 2, set up two concentric guide pin bushings 5 between oblique ejector pin 2 and movable mould board 1 promptly, guide pin bushing 5 adopts standardized design requirement, has the standard component to sell on the market, and maintenance, change convenience. The two guide sleeves 5 are separated by the spacer bush 6, so that the concentricity of the inclined ejector rod 2 is higher, the inclined ejector precision is better, and the product quality is improved. The two concentric guide sleeves 5 are fixed by clamp springs, and the clamp springs are fixed conveniently and firmly.
Be equipped with mounting groove 7 on the universal slide 4, the activity is provided with installed part 8 in the mounting groove 7, the mode that oblique ejector pin 2 passes through the pin joint is installed on installed part 8, be equipped with arc positioning groove in the mounting groove 7 on the relative both sides wall, be equipped with opening type self-lubricating axle sleeve 9 in the arc positioning groove, be equipped with slide-shaft 10 in the opening type self-lubricating axle sleeve 9, be provided with the locating hole on the slide-shaft 10, be equipped with on the installed part 8 and arrange in the locating hole and can move about the location arch 11. The utility model discloses an oblique ejector pin 2 is in the motion process, and the slide shaft makes a round trip interactively at opening type self-lubricating axle sleeve 9, because opening type self-lubricating axle sleeve 9's self-lubricating type, the emergence of the dead phenomenon of universal slide 4 card is avoided in the wearing and tearing of reduction slide shaft and opening type self-lubricating axle sleeve 9 that can be very big.
