Abstract
The utility model discloses a side core-pulling mechanism and relates to the plastic mold industry. The mechanism comprises an inner core, a sliding block, a sliding block seat, a base and an oil cylinder, wherein the sliding block seat is fixed to the base, the sliding block is located on the sliding block seat and is connected to the sliding block seat in a sliding mode, the inner core is fixedly connected to one side of the sliding block, and a telescopic rod of the oil cylinder is fixedly connected to the other side of the sliding block. The mechanism is characterized in that a projection is arranged at one end of the inner core, which corresponds to the base, a chute is arranged on the base, and the projection is arranged in the chute in a clamping mode. According to the mechanism, the projection at the lower end of the inner core is arranged in the chute of the upper end of the base, the position of the inner core is aligned, the inner core is prevented from swinging, the inner wall of a product cannot be scratched, the core-pulling motion is stable and the defect rate of products is reduced.
Description
Technical field
The utility model relates to the mould of plastics industry, particularly a kind of side core-pulling mechanism.
Background technology
Along with the propelling of product mass production, more and more higher to the quality requirement of mould, the kinetic stability of mechanism all can have influence on the quality of product in the mould.
A kind of cross section as shown in Figure 1 is the product of " Ω " shape, and size of arch abutment S1 is greater than the size of openend S2 on it, and the length of this product is longer, for the consideration of mold height, generally the product traverse can be come discharge.
For allow product when the die sinking aspect the demoulding, generally can adopt slide block side core-pulling mechanism to come the demoulding.But the stroke that is fixed on the inner core on the slide block is oversize, and the position of slider guide is too short, after slide block breaks away from take-up housing, rocking may appear in inner core, the motion of loosing core is unstable, can affect the fineness of linearity and the product inwall of product, causes the fraction defective of product to increase.
The utility model content
For solving the problems of the technologies described above, the utility model provides a kind of side core-pulling mechanism, to realize the purpose that motion is steady, reduce the product fraction defective of loosing core.
For achieving the above object, the technical solution of the utility model is as follows:
A kind of side core-pulling mechanism comprises inner core, slide block, take-up housing, base and oil cylinder, and described take-up housing is fixed on the described base; Described slide block is positioned on the described take-up housing, and is slidingly connected with described take-up housing; Described inner core is fixedly connected on a side of described slide block, the expansion link of described oil cylinder is fixedly connected with the opposite side of described slide block, it is characterized in that, an end of the corresponding described base of described inner core is provided with projection, be provided with chute on the described base, described projection is fastened in the described chute.
Preferably, the shape of described projection and described chute is T shape.
Preferably, the bottom of described slide block is provided with hanging platform, and corresponding described hanging platform place is provided with groove on the described take-up housing, and described hanging platform is arranged in described groove.
Pass through technique scheme, the side core-pulling mechanism that the utility model provides, the projection of the T shape of the lower end by inner core is fastened on the position of coming the correcting inner core in the chute of T shape of base upper end, prevented that rocking from appearring when sliding in inner core and the inwall of scratching products in base, realized loosing core motion steadily, reduce the purpose of product fraction defective.
Description of drawings
In order to be illustrated more clearly in the utility model embodiment or technical scheme of the prior art, the below will do to introduce simply to the accompanying drawing of required use in embodiment or the description of the Prior Art.
Fig. 1 is a kind of cross sectional representation of product;
Fig. 2 is the front view of the disclosed a kind of side core-pulling mechanism of the utility model embodiment;
Fig. 3 and Fig. 4 are the side view of the disclosed a kind of side core-pulling mechanism of the utility model embodiment.
The specific embodiment
Below in conjunction with the accompanying drawing among the utility model embodiment, the technical scheme among the utility model embodiment is clearly and completely described.
The utility model provides a kind of side core-pulling mechanism (with reference to Fig. 2), comprises inner core 4, slide block 3, take-up housing 2, base 5 and oil cylinder 1, and take-up housing 2 is fixed on the base 5.Slide block 3 is positioned on the take-up housing 2, and is slidingly connected with take-up housing 2.The bottom of slide block 3 is provided with hanging platform 31, and corresponding hanging platform 31 places are provided with groove (not indicating among the figure) on the take-up housing 2.Hanging platform 31 is arranged in groove, controls the glide direction of slide block 3.
As shown in Figure 3, inner core 4 is fixedly connected on a side of slide block 3, and the expansion link of oil cylinder 1 is fixedly connected with the opposite side of slide block 3.The lower end of inner core 4 is provided with the projection 41 of T shape, and the upper end of base 5 is provided with the chute of T shape, and projection 41 is fastened in the chute, comes the position of correcting inner core 4 on base 5, prevents that rocking from appearring when sliding in base 5 in inner core 4 and the inwall of scratching products.
As shown in Figure 4, the chute of the projection 41 of the lower end of inner core 4 and the upper end of base 5 is designed to the effect that dove-tail form also can reach correcting inner core 4, does not do concrete introduction at this.
The utility model is installed in the mould, and base 5 is equivalent to the mavable module core of mould.After mould was opened, dynamic model fell back on assigned address backward, and the expansion link of oil cylinder 1 is regained, and slide block 3 can go to the direction cunning of oil cylinder 1 with inner core 4.When inner core 4 broke away from product fully, the push rod on the dynamic model advanced, and product is ejected.
The side core-pulling mechanism that the utility model provides, the projection of the T shape of the lower end by inner core is fastened on the position of coming the correcting inner core in the chute of T shape of base upper end, prevent that rocking from appearring when sliding in inner core and the inwall of scratching products in base, realized loosing core motion steadily, reduce the purpose of product fraction defective.
To the above-mentioned explanation of the disclosed embodiments, make this area professional and technical personnel can realize or use the utility model.Multiple modification to these embodiment will be apparent concerning those skilled in the art, and General Principle as defined herein can in the situation that does not break away from spirit or scope of the present utility model, realize in other embodiments.Therefore, the utility model will can not be restricted to these embodiment shown in this article, but will meet the widest scope consistent with principle disclosed herein and features of novelty.
