Abstract

The invention discloses a mold mechanism using an inclined guide pillar and a sliding block for secondary pushing out. The mold mechanism comprises mechanisms of a push rod fixing plate, the sliding block, the inclined guide pillar, a movable mold supporting plate, a spring, a center push rod, a mold core, a movable mold cavity plate, a push rod, a movable mold base plate, a fixed mold plate, a pouring gate bush and the like. The connection mode of the mold mechanism is that: the push rod fixing plate 1 is in clearance fit with the push rod 9; the push rod 9 is in clearance fit with the movable mold supporting plate 4 and is in slide fit with a mold core fixing plate; and then the push rod 9 is tightly connected with the movable mold cavity plate 8 by using screws. The sliding block 2 is in slide fit with the push rod fixing plate 1. The inclined guide pillar 3 is tightly fixed in an inclined hole of the movable mold supporting plate 4 and is in clearance fit with an inclined hole on the sliding block 2. The center push rod 6 is in clearance slide fit with the mold core, and the tail end is in slope movement with the sliding block 2. The mold core 7 is in clearance slide fit with the movable mold cavity plate 8, and the spring 5 is fixed in inner holes of the mold core 7 and the movable mold supporting plate 4. The mold mechanism is very reliable in motion, is simple in mold structure, and is suitable for molding injection molds and metal die-casting molds.

Description

A kind of mold mechanism that utilizes Angle Pin and slide block secondary to release

Technical field

The present invention relates to injecting molding die and die cast metal mould molding, is a kind of mould structure that utilizes Angle Pin and slide block secondary to release.

Background technology

In simple mould emptier, no matter adopt which kind of mould emptier, the release action of its goods all is one step completed.But some goods adopts when once releasing, and is often yielding, even destroys, and some goods can not come off automatically, or be difficult to take out from die cavity after once releasing action.Therefore, this based article need be released by secondary, to disperse ejection resistance, make the goods demoulding smoothly, this mechanism that finishes a goods demoulding by two release actions is called the secondary mould emptier.At present, at the secondary mould emptier that mould circle adopted following several pattern: A, single push pedal secondary mould emptier are arranged; B, projection drag hook secondary mould emptier; C, wedge slide block type secondary mould emptier; D, centering block rod-pulling type secondary mould emptier.Because there is the following defective in said mechanism in the actual production manufacturing: make the Installation and Debugging inconvenience, as spring secondary ejecting mechanism, because matched moulds often, the frangibility spring causes stuckly in mould, even breaks mold cores and die cavity.Another defective, during die sinking just, spring can not work at once, after the die sinking, make the goods can't the demoulding, realize This move, spacing somatotype mechanism must be set, so just cause the mold mechanism complexity, make defectives such as difficulty, the defective that exists in the said mechanism, I am combined in mould and design line working experience for many years, the mold mechanism that provides following a kind of secondary to release.

Summary of the invention

The present invention provides the mold mechanism of a kind of Angle Pin and the release of slide block secondary, and its action is solid and reliable, and the pressure transmission is good, and mould is made very convenient, and mould in the course of the work flexibly, steadily behind the matched moulds, is released element and can be got back to original position at every turn.This mechanism also possesses the following advantage simultaneously: 1. can play the guiding of solid plate motion and the supporting role after the die sinking.2. force the push pedal fixed head to drive push rod and reset rapidly, thereby avoid side core and push rod to interfere.3. during die sinking, first release link breaks away from ejector sleeve, and injection putter promotes ejector pin retaining plate and drives on the ejector sleeve and move, and does not influence and releases finishing of action.Therefore 4. because push rod resets rapidly, before matched moulds, the push rod end that just resets can avoid releasing part and moving core interferes.5. because the push rod end face contacts with the push piece plate, can play reset response, simultaneously under the condition of goods geometry and mould structure permission, can utilize push rod double as release link, a part that is the push rod end face contacts with goods, makes push rod usefulness, and another part makes to reset usefulness.

The present invention is further described below in conjunction with accompanying drawing

1--ejector pin retaining plate 2--slide block 3--Angle Pin

4--dynamic model support plate 5--spring 6--center push rod

7--core 8--dynamic model cavity plate 9--push rod

The specific embodiment:

It shown in the figure a kind of mold mechanism that utilizes Angle Pin and slide block secondary to release.When the mould clamping is on injector or die casting machine, behind injection or the die cast, mould is opened, and injection device or die casting equipment are finished for the first time and released, and Angle Pin 3 drives slide block 2 and moves to mold center simultaneously, figure C is that injector or die casting machine push rod continue to eject, slide block is with top shoe inclined-plane, center push rod 6 top, and it is more leading than push rod 9 to make push rod 6 release distance, will release in the driven model cavity plate 8 of goods, finish for the second time and release, center push rod resets by spring 5 simultaneously.During matched moulds, because the cover half cavity plate is contacted by movable model control plate 8, the dynamic model cavity plate forces the superincumbent push rod 9 of connection to reset, and push rod 9 forces ejector pin retaining plate 1 and push pedal to reset, and finishes sealing up to the mould die joint and stops action.The batch process of goods is back and forth carried out in above-mentioned action.

Claims

1. mold mechanism that utilizes inclined-plane guide pillar and slide block secondary to release, its main feature is that some goods adopts when once releasing, and is often yielding, even destroys.Some goods is after once releasing action, can not come off automatically or be difficult to and from die cavity, take out, and a kind of ejecting mechanism that adopts, this mechanism releases the mode that a goods demoulding is finished in action by two, when releasing for the first time, to disperse ejection resistance, make goods loosening, when releasing for the second time, after having disperseed ejection resistance, carry out, make the smooth demoulding of goods like this, this mechanism is moved to mold center by Angle Pin driving slide block simultaneously, and slide block is with top shoe inclined-plane, center push rod top, it is more leading than push rod to make push rod release distance, with releasing in the driven model cavity of goods, finish the disengaging of goods, this mechanism action is very reliable, the pressure transmission is good, mould is made, installation and maintenance are very convenient, and this mechanism's safety and environmental protection is of value to the economic worth of promoting the use of.
