Abstract

The utility model discloses an injection mold for front shells of air conditioners. The injection mold is composed of a first spring, a connecting push rod, a second spring, a fixed clamping plate, a fixed die cavity plate, a push block 1, a fixed die insert, a push rod, a die core, a side slide block, an oblique guide pillar, an oblique press block and a push block 2, wherein the connecting push rod (2) of the mold is movably connected with an ejector plate, the connecting push rod (2), after in sliding fit with a movable mold plate, is fastened on the push block 1 (6) by using a bolt, a parting surface of the fixed die cavity plate (5) is matched with the movable mold plate in a convex-concave match mode, and the fixed die insert (7), after arranged in a step hole of the fixed die cavity plate (5), is compressed by using the fixed clamping plate (4), and then fastened on the fixed clamping plate (4) by using bolts.

Description

Air conditioner fore shell injection molding

Technical field

The present invention relates to mould for plastics, is air conditioner fore shell injection molding.

Background technology

At present, on the Design of Dies of air conditioner fore shell, be all to adopt rack-and-pinion, hydraulic pressure, air pressure, screw thread rotation completes looses core, although it is solid and reliable that these mechanisms move, pressure transmits, quality of item is excellent, but owing to being subject to the large impact in goods perspective plane, when mould is manufactured, die holder volume itself is just large, while is mounting strap moving gear tooth bar outside mould again, hydraulic pressure, these auxiliary components of pneumatic cylinder, this just causes mould volume larger, simultaneously, manufacture these auxiliary components and spend again a lot of time, like this new product release is brought to very big impact, particularly auxiliary component is being manufactured, install, debugging, very inconvenient during maintenance.In the design of entering to water, be all to adopt drop gate to enter to water at present, though pressure is good when it enters to water, mold filling speed is fast, but drop gate, owing to entering to water the diameter of the cast gate at place at Φ 8-Φ 10mm, therefore cause goods when mould external cutting off cast gate, labor strength is large, very easily scrap goods simultaneously, because cast gate is large, after excision, product appearance quality is brought to great impact on the other hand.In order to overcome the problems referred to above, spy provides following a kind of mould to solve the problems referred to above.

Summary of the invention

The present invention is to provide air conditioner fore shell injection molding, this die feature is: adopt multiple spot tunnel gate to enter to water, adopt Angle Pin somatotype to loose core simultaneously, because shell product profile before air-conditioning is large, dark, complex structure, appearance requires high simultaneously, do not allow gate vestiges, be therefore designed to the injection moulding of multiple spot tunnel gate.During die sinking, Angle Pin drives side slide somatotype and looses core, and goods and cast gate are all stayed dynamic model on one side.During release, by push rod, pushing block, promote goods simultaneously, make it depart from dynamic model.Cast gate is released and is automatically cut off by push rod.When goods are deviate from after core, spring continues to promote to connect push rod and pushing block, makes goods self falling.Another effect of spring is to guarantee to take pushing block release as main, in case goods produce distortion during anti-avulsion mould.Be designed with wedge press block, it is the strength and stiffness of strengthening cover half cavity plate simultaneously.Air conditioner fore shell injection molding, solved and adopted rack-and-pinion, hydraulic cylinder, cylinder, when screw thread rotation is loosed core, mould structure is complicated and owing to being subject to the large impact in goods perspective plane, when mould is manufactured, die holder volume itself is just large, while is mounting strap moving gear tooth bar outside mould again, hydraulic pressure, these auxiliary components of pneumatic cylinder, cause mould volume larger, simultaneously, manufacture these auxiliary components and spend again a lot of time, like this new product release is brought to very big impact, particularly these auxiliary components are being manufactured, install, debugging, very inconvenient problem during maintenance, employing drop gate goods have been solved when mould external cutting off cast gate, labor strength is large, very easily scrap goods simultaneously, on the other hand because cast gate is large, after excision, product appearance quality is brought to the problem of great impact.Air conditioner fore shell injection molding, it is characterized in that: connect push rod (2) and be flexibly connected with ejector retainner plate, connecting after push rod (2) is slidably matched with moving platen uses screw fastening again on pushing block one (6), the die joint of cover half cavity plate (5) coordinates with moving platen convex-concave, cover half mold insert (7) compresses with top clamping plate (4) after being arranged in the stepped hole of cover half cavity plate (5), then use screw fastening on top clamping plate (4), push rod (8) is fastened on ejector retainner plate and with moving platen and becomes matched in clearance with the hole on core (9), baroclinic block (12) is arranged in moving platen and uses soket head cap screw fastening.

Accompanying drawing explanation

Below in conjunction with accompanying drawing, the present invention is further described

Shown in figure:

Fig. 1 is mould matched moulds situation sectional side elevation

Fig. 2 is that mould enters to water the ranking figure with slide block

Sectional side elevation and cooling water channel figure when Fig. 3 is matched moulds cast

In figure, numeral number represents respectively:

1---the first spring 2---connection push rod 3---the second spring

4---top clamping plate 5---cover half cavity plate 6---pushing blocks one

7---cover half mold insert 8---push rod 9---cores

10---side slide 11---Angle Pin 12---baroclinic blocks

13---pushing block two

The specific embodiment:

Shown in figure, it is air conditioner fore shell injection molding, its specific embodiment is as follows: this mould is in order to solve products appearance problem, therefore when Design of Runner System, adopt multiple spot sub marine gate, when mould is installed in injector, after injection moulding, under pressurize, the power of cooling rear mold in injector, drive dynamic model to partially open die joint, at this moment Angle Pin (11) drives side slide (10) carry out side somatotype and loose core, and goods and cast gate are all stayed dynamic model on one side.When die sinking is apart from being greater than after goods height, injector stops action, and now injector and push rod promote ejector retainner plate drive push rod (8), pushing block one (6) and pushing block two (13) and promote goods simultaneously, make goods depart from dynamic model.Cast gate is released by push rod and is automatically cut off in mould simultaneously.When goods are deviate from after core (9), spring (3) continues to promote to connect push rod (2) and pushing block one (6) and pushing block two (13), and goods are dropped out outside mould by deadweight.The second spring (3) guarantees take that pushing block one (6) and pushing block two (13) release as main simultaneously, in case goods produce distortion during anti-avulsion mould.The first spring (1) guarantees that release system resets in advance.Baroclinic block (12) is strengthened the strength and stiffness of cover half cavity plate (5).During matched moulds, return bar contacted with cover half cavity plate (5) before this, the push rod (8) that the counter-pressure of cover half cavity plate (5) forces return bar to drive and is arranged on ejector retainner plate resets, after push rod (8) resets, Angle Pin (11) drives side slide (10) to make homing action, until mould, respectively open part and complete after reset, active and inactive mold is locked die joint, just carries out the moulding by casting in next cycle.
