Abstract:
Heated mould cavities of injection-moulding dies require long heating and cooling phases, with the result that the production unit numbers are low, the unit costs are high and the degree of efficiency is low as a result of the energy for temperature control. It is therefore a problem of the invention to eliminate or to reduce these disadvantages. According to the invention, this is solved by virtue of the fact that a die insert for delimiting, at least in sections, a mould cavity which is configured in a moulding plate of an injection-moulding die for producing components from a flowable material is provided with a main body which has a shaping front side for the mould cavity and a rear side which lies opposite the shaping front side, wherein the main body carries a layer heating means on the shaping front side thereof.
Abstract:
An injection-molding tool (1) for a clamping unit of an injection-molding machine for producing injection-molded parts, comprising a frame tool, consisting of a first, nozzle-side tool half (2) and a second, ejector-side tool half (3), is described. Mold insert halves (50, 51) of at least one mold insert (11) are fitted in slide-in frames (9, 10). The slide-in frames (9, 10) with the at least one mold insert (11) fitted in them can be connected to one another to form a slide-in module (8) which in the modifying process can be removed as a whole from the frame tool, which in the modifying process remains connected to the injection-molding machine.
Abstract:
A rotary knob assembly and methods for forming and controlling friction effecting features of the knob assembly are disclosed. The knob assembly includes a mounting structure and a knob. The knob is rotatably coupled to a bezel of the mounting structure. The knob includes a stabilizer, a guide member, and a retainer having a patterned surface. At least a portion of the stabilizer is disposed between the bezel and the retainer to maintain an axial position and a radial position of the knob. A detent formed on the guide member cooperates with a patterned surface of the retainer to provide a haptic feedback to a user.
Abstract:
A mold core package for forming a molding tool includes a plurality of stacked particulate layers having a binding agent. The plurality of stacked particulate layers form sacrificial walls defining a mold cavity. A sacrificial displacement line and a sacrificial displacement body extend from the mold core package and are adapted to displace a molten material applied to the mold core package.

Abstract:
A 3-plate mold assembly with a common mold base comprises: a stationary mold mounted on a fixed side of an injection molding machine and a movable mold mounted on a movable side of the injection molding machine. The stationary mold comprises a stationary-side fixed plate on which are disposed four pillars to be inserted through a stripper and into a female insert assembly. When new products need to be produced, it only needs to replace the female and male insert and the rest parts of the stationary and movable molds don't need to be replaced, thus substantially saving production cost.
Abstract:
The invention relates to an integral irradiation unit for hardening light-hardening polymer compositions, a method for producing hardened polymer molded bodies or bodies coated with hardened polymers using the integral irradiation unit, and to the use of the integral irradiation unit for producing molded polymer bodies or bodies coated with polymers.
Abstract:
A mold apparatus with replaceable mold plates comprises mold bases, and positioning units used to position mold plates on the respective mold bases. If the positioning units are removed, the mold plates can be easily replaced in such a manner that the mold plates are made to slide along the positioning units, facilitating the replacement of the mold plates. Since the mold plates can be quickly replaced, when different products are going to be produced, it only needs to redesign new mold plates with new forming blocks, and the new mold plates can also be applied to the original mold bases as long as they are formed with the guide grooves for cooperating with the positioning portions of the positioning units, greatly reducing the production cost while producing high economic benefits.
Abstract:
Disclosed is an injection mold, comprising a moving half, a fixed half and a plurality of bearing plates positioned therebetween. The moving half comprises a moving half plate and a moving half core positioned thereon. The fixed half comprises a fixed half plate and a fixed half cavity positioned thereon. The bearing plates are positioned on one of the fixed half plate and the moving half plate and a bearing surface is formed thereon. The moving half core and the fixed half cavity contact with each other partially to form an arrangement surface. With the bearing plates positioned therebetween, the bearing surface and the arrangement surface can undertake the closing mold pressure generated by an injection molding machine together for reducing the arrangement surface area. The molding is easy and cost drops to improve productivity. The closing mold balance of the entire injection mold can be preferably ensured.
Abstract:
According to embodiments of the present invention, there is provided a cavity insert for a molding system, the cavity insert having a deformable portion. More specifically, A cavity insert (106) is provided, the cavity insert (106) is for a molding stack (102) for use in an injection mold, the cavity insert (106). The cavity insert (106) comprises a body (122) configured to be received, in use, within a cavity plate (104) of the injection mold; the body (122) defining: a cavity molding surface (124) along an inner portion thereof; a circumferentially deformable portion (123); and an actuator interface (134) configured to cooperate, in use, with a complementary actuating interface (136) that is defined on a compression member (138) to generate a compressive force that selectively elastically deforms the circumferentially deformable portion (123).
