Abstract
The utility model provides an inner groove demoulding structure for plastic injection products, mainly relating to a die of plastic injection products. The inner groove demoulding structure comprises sliding blocks, a pitched roof, a spring, a shoveling machine, a bottom plate, a limiting block, a needle bottom plate and a thimble plate, wherein the sliding blocks are arranged at four oblique opposite angles of the inner cavity of a product, and incline by forming an angle of 45 degrees with the surface of the inner cavity of the product; the shoveling machine at the front end of the sliding block clings to the inclined plane at the front end of the sliding block, the spring is arranged in the sliding block, and the limiting block on a rear die is fastened on the thimble plate by a bolt. The mechanism provided by the utility model has a reasonable and reliable structure, and twitches the sliding blocks at the four oblique corners to the center of the product under the action of the spring, so that the sliding blocks can be put in place accurately when moving oppositely or reversely, thus avoiding damage to the sliding blocks. The sliding blocks are ejected out of the whole product by an oblique injector after being twitched so as to realize the demoulding action.
Description
Technical field
The utility model relates to Mould Machining, particularly a kind of injecting products inner groovy mould emptier.
Background technology
Early stage mould structure is simple, mostly the groove position of plasthetics is by hand ejection, its production efficiency is low, cost is higher, but along with society is increasing to the demand of plastic cement products, the inner groovy of existing product or the mould of back-off structure, when product is used for the slide block shaping, because most of finished product is wrapped in slide block, like this when die sinking, finished product is easily pulled or is broken, and causes the normally demoulding, so product generally all needs to carry out secondary operations, cause the process-cycle of product long, can not one-shot forming.
The utility model content
The purpose of this utility model is to overcome the deficiencies in the prior art a kind of injecting products inner groovy mould emptier is provided, and reaches the purpose of product one-shot forming, process-cycle weak point, saving cost, raising yield rate.
Technical solutions of the utility model are as follows: a kind of injecting products inner groovy mould emptier; comprise slide block 1, oblique top 2, spring 3, shovel machine 4, base plate 5, limited block 6, pin base plate 7, ejector retainner plate 8; it is characterized in that described slide block 1 is located at four diagonally opposing corner positions of die cavity in the product; be miter angle with mold cavity surface in the product; the shovel machine 4 of slide block 1 front end is close to the inclined-plane of slip front; the inside of this slide block 1 is provided with spring 3, and the limited block 6 usefulness screws on the back mould are fastened on the ejector retainner plate 8.
Described slide block 1 is after die sinking, and after slide block 1 broke away from shovel machine 4, under the effect of spring 3, to loosing core, the demouldings were realized at four angles of product in the miter angle obliquity rectilinear motion; The injection machine push rod ejects pin base plate 7 to limited block 6 spacing places, and oblique top 2 ejects product integral body, the demoulding smoothly.
During matched moulds, oblique top 2 at first resets, and slide block 1 rear makes slide block 1 advance core under the effect of guiding surface then, and slide block 1 compresses and makes spring be in compressive state.
After adopting such scheme, the utility model has following advantage: this is rational in infrastructure, and is practical, it at first twitches four oblique angle slide blocks to product center in die sinking, stopper slot is arranged on the slide block, make slide block in opposite directions or can both be correct during reverse motions put in place, avoid damaging slide block.Eject back mould skewback by oblique top again after slide block is twitched and realize demoulding action.

Fig. 2 is the structural front view of the utility model structure;
Fig. 3 is the structural representation of the utility model structure.
The specific embodiment
In order better to understand the utility model content, the utility model is further specified below in conjunction with accompanying drawing.
Consult accompanying drawing 1,2; a kind of injecting products inner groovy of the utility model mould emptier; comprise slide block 1, oblique top 2, spring 3, shovel machine 4, needle plate, base plate 5, limited block 6, pin base plate 7, ejector retainner plate 8; it is characterized in that described slide block 1 is located at four diagonally opposing corner positions of die cavity in the product; be miter angle with mold cavity surface in the product; the shovel machine 4 of slide block 1 front end is close to the inclined-plane of slip front, and the inside of this slide block 1 is provided with spring 3, and the limited block 6 usefulness screws on the back mould are fastened on the ejector retainner plate 8.
Consult accompanying drawing 3, when slide block 1 after die sinking, after slide block 1 broke away from shovel machine 4, under the effect of spring 3, to loosing core, the demouldings were realized at four angles of product in the miter angle obliquity rectilinear motion; The injection machine push rod ejects spacing place to limited block 6 with pin base plate 7, and oblique top 2 ejects product integral body, the successful demoulding.
During matched moulds, oblique top 2 at first resets, and slide block 1 rear makes slide block 1 advance core under the effect of guiding surface then, and slide block 1 compresses and makes spring be in compressive state.
This is rational in infrastructure, practical for the utility model, and it at first twitches four oblique angle slide blocks to product center under the effect of spring in die sinking, make slide block in opposite directions or can both be correct during reverse motions put in place, avoid damaging slide block.Eject entire product by oblique top again after slide block is twitched and realize demoulding action.
Embodiment only is a preferred optimum implementation of the present utility model in sum; unintelligible is that protection domain of the present utility model is limited; for adjustment that does not exceed technical solutions of the utility model and the change that the technical work personnel of this area do according to the utility model, should think and drop in the protection domain of the present utility model.
