Abstract

The utility model provides a sliding block thimble delay ejector mechanism which comprises a T-shaped pulling block, a sliding block, a fixing base and a sliding block thimble device, wherein a sliding groove for accommodating the T-shaped pulling block is formed in the fixing base; the sliding block thimble device is arranged inside a through hole of the sliding block, is connected with the fixing base through a bolt and further comprises a telescopic head, a sliding block thimble and a spring; the spring is arranged inside the telescopic head and is in matching connection with the sliding block thimble. The sliding block thimble delay ejector mechanism is simple in structure, low in processing cost, small in occupying space, stable and reliable in operation and high in precision and practicability.

Description

A kind of slide block thimble Delayed ejection mechanism

Technical field

The utility model relates to mould applications, refers to especially a kind of slide block thimble Delayed ejection mechanism.

Background technology

All the time, in the design and manufacture process of plastic, often there will be the recessed or plagioclase hole of side.Because side is recessed or plagioclase hole different from die sinking direction (vertical or angled), plastic can not direct demold, therefore must Element Design moulding side is recessed or plagioclase hole become mobilizable in mould structure design, be called moving core, before the plastic demoulding, must first carry out undercut, moving core is extracted out, and plastic can the demoulding, and complete this moving core, takes out the mechanism of mountain and reset and is called oblique core-pulling mechanism.Conventionally, the mode of loosing core of oblique slotted hole is rack-and-pinion pulled core structure, though this mechanism can meet the production requirement of such part, along with day by day improving and the raising day by day of labor productivity product appearance quality requirement.

Utility model content

The deficiency existing for prior art, it is a kind of simple in structure that the purpose of this utility model is to provide, and processing cost is low, it is little to take up room, convenient disassembly and practical slide block thimble Delayed ejection mechanism.

The technical solution of the utility model is achieved in that a kind of slide block thimble Delayed ejection mechanism, comprises T-shaped pulling block, slide block, holder and slide block thimble device; On described holder, be provided with the chute of placing T-shaped pulling block; Described slide block thimble device is arranged in slide block through hole, and is connected with holder by bolt; Slide block thimble device also comprises telescopic head, slide block thimble and spring; Described spring is arranged in telescopic head, is then connected with slide block thimble.

Further, in described T-shaped pulling block, be provided with perpendicular type groove; The telescopic head of described slide block thimble device contacts with perpendicular type groove.

A kind of slide block thimble Delayed ejection mechanism of the present utility model, a kind of simple in structure, processing cost is low, it is little, reliable and stable to take up room, precision is high and practical.

The specific embodiment

Below in conjunction with the accompanying drawing in the utility model embodiment, the technical scheme in the utility model embodiment is clearly and completely described, obviously, described embodiment is only the utility model part embodiment, rather than whole embodiment.Embodiment based in the utility model, those of ordinary skills are not making the every other embodiment obtaining under creative work prerequisite, all belong to the scope of the utility model protection.

As shown in Figure 1, Figure 2 with shown in Fig. 5: a kind of slide block thimble Delayed ejection mechanism, comprises T-shaped pulling block 2, slide block 3, holder 1 and slide block thimble device 4; On described holder 1, be provided with the chute 11 of placing T-shaped pulling block 2; Described slide block thimble arranges 4 in slide block through hole 31, and is connected with holder 1 by bolt.

Above-mentioned a kind of slide block thimble Delayed ejection mechanism, slide block thimble device 4 also comprise telescopic head 42 and spring 41; Described spring 41 is arranged in telescopic head 42, is then connected with slide block thimble 43.

In above-mentioned a kind of slide block thimble Delayed ejection mechanism, described T-shaped pulling block 2, be provided with perpendicular type groove 21; The telescopic head 42 of described slide block thimble device 4 contacts with perpendicular type groove 21.

Operation principle: in the time of die sinking, realize the object of slide block thimble delayed ejection by telescopic head 42 and the assembly relation of T-shaped pulling block 2; As shown in Figure 3 and Figure 6: figure die sinking is in the time of the first stage, and first T-shaped pulling block 2 moves up, slide block 3 is moved to the left apart from S simultaneously, and telescopic head 42 withstood T-shaped pulling block 2 and kept static at that time; As shown in Fig. 4 and Fig. 7: in the time of die sinking second stage, when T-shaped pulling block 2 upwards continues to move, the degree of depth of the perpendicular type groove 21 of T-shaped pulling block 2 is that under having, change is up large, when telescopic head 42 does not withstand perpendicular type groove 21, slide block 3 is just moved to the left and departs from slide block together with slide block thimble device 4 like this.

The foregoing is only preferred embodiment of the present utility model; not in order to limit the utility model; all within spirit of the present utility model and principle, any modification of doing, be equal to replacement, improvement etc., within all should being included in protection domain of the present utility model.
