Problems solved by technology

[0004] When using injection molding equipment to inject the outer panel of the back door of the car, because the hot melt raw material is poured into the mold, it contacts with the inner wall of the mold, and the temperature of the mold wall is low, and the molten material is easy to shrink and concentrate due to cold. Causes voids to appear easily during the pouring molding process

Embodiment 1

[0027] as attached figure 1 to attach Figure 6 Shown:

[0028] The invention provides an injection molding equipment for the outer panel of the back door of an automobile. The structure is provided with a base 1, a fixed template 2, a movable template 3, a clamping post 4, a handle post 5, a control plate 6, a top template 7, The pouring gun 8, the fixed formwork 2 is embedded and positioned above the base 1, the movable formwork 3 is movably engaged above the fixed formwork 2, and the locking column 4 is embedded and connected to the top end of the movable formwork 3, so that The lifting handle column 5 is embedded and connected to one side of the movable template 3, the control plate 6 is connected to the side end of the fixed template 2, and the top template 7 is installed through the top of the movable template 3. One end of the pouring gun 8 is connected with the control volume plate 6, and the pouring gun 8 is connected through the movable formwork 3 and the top formw...

Embodiment 2

[0036] as attached Figure 7 Shown:

[0037] Wherein, the pressure body 526 is provided with a connection block 261, a cavity 262, a limiting edge 263, a pulling rod 264, a balloon 265, and a pressure end edge 266, and the cavity 262 and the connection block 261 are an integrated structure. And located inside the connecting block 261, the limiting edge 263 is embedded and installed inside the connecting block 261, one end of the pulling rod 264 is connected with the balloon 265 and movably matched, and the other end of the pulling rod 264 is connected to the balloon 265 connected and movably matched, the pressure-receiving end edge 266 moves outside the limiting edge 263, the balloon 265 is movably engaged with the limiting edge 263, and the limiting edge 263 is made of resin material in an arc shape. The balloon 265 is a sphere of plastic elastomer material, which has excellent elastic force; the pulling rod 264 is a rubber stick, which has a certain toughness supporting for...

Abstract

The invention discloses injection molding and mold opening equipment for an automobile back door outer plate. The injection molding and mold opening equipment is structurally provided with a base, a fixed molding plate, a movable molding plate, a clamping column, a lifting handle column, a quantity control plate, a top molding plate and a pouring gun, wherein hot melt materials have punching forceon a pressed body, a tube sleeve is driven to extend towards the rear end, and the tube sleeve changes from a folded state to an extending and extending state; the high temperature of the hot meltingmaterial enables a connecting pulling belt to expand in the containing cavity, the folded sleeve wall is assisted to extend to the maximum extent, a bottom strip also expands when meeting heat at thebottom to form an annular isolation ring, so that the situation that when poured into a pouring inlet, the hot melt materials shrink in a concentrated mode due to the low temperature and are prone tosolidification is avoided; when poured, the hot melt materials stamp the pressed body, and the pressed end edge is deformed to extrude backwards in a concave mode, so that the pressed end edge is deformed towards a limiting edge strip to an arc shape similar to a limiting edge while pressed, and thus, the stamped hot melt materials have greater bearing pressure, and are moved easier to the rear end.

Description

technical field [0001] The invention belongs to the field of injection mold opening, and more specifically relates to an injection mold opening equipment for an automobile back door outer panel. Background technique [0002] Injection molding equipment is widely used in the field of model processing. It is a device that can solidify and shape products after pouring by personnel. It can produce plastic parts with complex shapes in large quantities and quickly. [0003] Based on the inventor's discovery above, the existing automobile back door outer panel injection mold opening equipment has the following deficiencies: [0004] When using injection molding equipment to inject the outer panel of the back door of the car, because the hot melt raw material is in contact with the inner wall of the mold after pouring into the mold, the temperature of the mold wall is low, and the molten material is easy to shrink and concentrate due to cold. As a result, voids are prone to occur d...
