Abstract

The utility model relates to a plastic injection mould capable of protecting the multiple opening for an axle sleeve. A core fixing plate is fixedly connected with a movable mould seat plate through screws, and a core and a guide post are respectively fixed on the movable mould seat plate through the core fixing plate. A stripper plate is arranged on the core fixing plate through the core and the guide post. The guide post is arranged on a cavity plate through a guide sleeve. A flow passage push plate is arranged on a spacing screw which is arranged on a fixed mould seat plate, and a flow passage spacing screw is fixed on the flow passage push plate. Core spacing plates are respectively fixed at both sides of the core fixing plate through the screws. A core spacing screw is fixed with the stripper plate, the spacing plates are respectively fixed at both sides of the stripper plate through the screws and a small spacing screw is fixed with the cavity plate. The utility model has the advantages of simple structure, reliable operation, high production efficiency, low cost, etc., and solves the technical problems of long forming cycle of the ordinary plastic mould and difficulty push of a deep cavity piece.

Description

A kind of repeatedly plastic injection mould of open form of axle sleeve of protecting

Technical field

The utility model belongs to plastic moulds technology, particularly a kind of repeatedly plastic injection mould of open form of axle sleeve of protecting.

Background technology

During plastic piece shaping, not only require good product quality, the production efficiency height, but also require mould structure simple, reduce production costs.To complicated working of plastics when the moulding, need repeatedly open form just can deviate from working of plastics, adopt existing normal injection mould, because the ejecting mechanism more complicated during working of plastics demoulding, needs a process that ejects, so just increased molding cycle, cause production efficiency low, and influence the service life of injection molding, exist the very difficult shortcoming of deviating from product automatically of injection mold.

The utility model content

The purpose of this utility model be at existing injection mold in the technical problem that the mould emptier of deviating from product automatically exists, provide the protection axle sleeve of a kind of simple in structure, reliable operation, production efficiency height and low cost of manufacture to mould repeatedly the plastic injection mould of open form.

The utility model comprises Bottom clamp plate, core fixing plate, the push piece plate, cavity plate, runner ejection plate, stop screw, top clamping plate, core, centring ring, sprue bush, the runner stop screw, guide pin bushing, guide pillar, the core limiting plate, the core stop screw, limiting plate, little stop screw, core fixing plate is fixedlyed connected by screw with Bottom clamp plate, core and guide pillar are separately fixed on the Bottom clamp plate by core fixing plate, the push piece plate passes through core, guide pillar is arranged on the core fixing plate, guide pillar is arranged on the cavity plate by guide pin bushing, guide pillar can slide in guide pin bushing, runner ejection plate is arranged on the stop screw, stop screw is arranged on the top clamping plate, top clamping plate, runner ejection plate, cavity plate, the push piece plate is arranged on the core fixing plate successively from top to bottom, the runner stop screw is fixed on the runner ejection plate, sprue bush is fixed on the top clamping plate by centring ring, the core limiting plate is separately fixed at the both sides of core fixing plate by screw, core stop screw and push piece plate are fixed, the core stop screw can slide in the core limiting plate, limiting plate is separately fixed at the Two side of push piece plate by screw, little stop screw and cavity plate are fixed, and little stop screw can slide in limiting plate.

The utlity model has advantages such as simple in structure, reliable operation, production efficiency height and low cost of manufacture, it is long to have solved the common plastics mould molding cycle, and dark chamber part ejects the difficult technologies problem.

Description of drawings

Fig. 1 is the structural representation that the A-A of Fig. 2 analyses and observe,

Fig. 2 is the vertical view of the utility model structure,

Fig. 3 is that the B of Fig. 2 is to structural representation;

Among the figure: 1 Bottom clamp plate, 2 core fixing plates, 3 push piece plates, 4 cavity plate, 5 runner ejection plates, 6 stop screws, 7 top clamping plates, 8 cores, 9 centring rings, 10 sprue bush, 11 runner stop screws, 12 guide pin bushings, 13 guide pillars, 14 core limiting plates, 15 core stop screws, 16 limiting plates, 17 little stop screws.

The specific embodiment

As shown in the figure, further specify the organization plan of the present utility model and the course of work in conjunction with example.

As shown in the figure; a kind of protection axle sleeve is the open form plastic injection mould repeatedly; comprise Bottom clamp plate 1, core fixing plate 2, push piece plate 3, cavity plate 4, runner ejection plate 5, stop screw 6, top clamping plate 7, core 8, centring ring 9, sprue bush 10, runner stop screw 11, guide pin bushing 12, guide pillar 13, core limiting plate 14, core stop screw 15, limiting plate 16, little stop screw 17.

As shown in Figure 1, core fixing plate 2 and Bottom clamp plate 1 are fixedlyed connected by screw, 4

cores

8 and 4 guide pillars 13 are separately fixed on the Bottom clamp plate 1 by core fixing plate 2, push piece plate 3 is by core 8, guide pillar 13 is arranged on the core fixing plate 2, guide pillar 13 is arranged on the cavity plate 4 by guide pin bushing 12, guide pillar 13 can slide in guide pin bushing 12, runner ejection plate 5 is arranged on the

stop screw

6,4 stop screws 6 are arranged on the top clamping plate 7, top clamping plate 7, runner ejection plate 5, cavity plate 4, push piece plate 3 is arranged on the core fixing plate 2 successively from top to bottom, 4 runner stop screws 11 are fixed on the runner ejection plate 5, and sprue bush 10 is fixed on the top clamping plate 7 by centring ring 9.

As shown in Figure 3,2 core limiting plates 14 are separately fixed at the both sides of core fixing plate 2 by screw, and core stop screw 15 is fixing with push piece plate 3, and core stop screw 15 can slide in core limiting plate 14.4 limiting plates 16 are separately fixed at the Two side of push piece plate 3 by screw, and little stop screw 17 is fixing with cavity plate 4, and little stop screw 17 can slide in limiting plate 16.

The course of work of the present utility model is: during die sinking, as shown in Figure 1, owing to embrace the effect of mould power, mould is along the I-I somatotype; Dynamic model part (Bottom clamp plate 1, core fixing plate 2, push piece plate 3) is when moving down 81mm, and cavity plate 4 is held by the little stop screw 17 on the limiting plate 16, and mould is along II-II face somatotype; When cavity plate 4 moved down 62mm, stop screw 6 was stuck on the cavity plate 4 with the nut of runner stop screw 11 lower ends, and mould is along the III-III somatotype; When runner ejection plate 5 moved down 10mm, the head of stop screw 6 was blocked by top clamping plate 7, stop motion, and mould is along the IV-IV somatotype; When IV-IV face somatotype 56mm, push piece plate 3 is held by the little stop screw 15 on the core limiting plate 14, and four times somatotype finishes.
