Abstract
The utility model discloses a can guarantee to mould the go up reinforced chamber plunger type transfer mould of a steady ejection of compact, including the bearing plate, lie in the lower die on bearing plate upper portion and lie in the down last die on die upper portion, form the die cavity between lower die and the last die, be equipped with reinforced chamber in the side direction of last die, reinforced chamber with the die cavity communicates with each other the middle part of die cavity is equipped with the core, and its characterized in that is equipped with two push rods with the core symmetry along vertical orientation on the die under, and in the die cavity was all stretched into on the upper portion of two push rods, the lower part of two push rods was all connected in a horizontally push pedal, the push pedal has the vertical degree of freedom.
Description
Technical field
The utility model relates to compression moulding die technical field, is specifically related to a kind of reinforced chamber plunger type transfer mould.
Background technology
The forming method of a kind of thermosetting plastics grown up on the basis of compression forming during injection-compression molding, the principle of injection-compression molding is that the raw material of preheating is added in reinforced chamber, plastics are through heating plasticizing, die cavity is clamp-oned through the running gate system of mould certificate under the pressure of press plunger, plastics in die cavity keep certain hour fully to solidify under certain pressure and temperature, obtain required plastic.Compression moulding die is divided into portable transfer mold and plunger type transfer mould, existing plunger type transfer mould, it often has the following disadvantages: after plastic parts moulding, during discharging, by means of only independent ejector beam, plastic is ejected from die cavity, the mode of this discharging, because the size of some plastic is larger, plastic often can not ensure the stationarity of plastic discharging when discharging, plastic easily collide with other positions, makes plastic surperficial generation scratch etc. and affects the Forming Quality of plastic.
Utility model content
The utility model is intended to provide a kind of upper reinforced chamber plunger type transfer mould ensureing the steady discharging of plastic.
Upper reinforced chamber plunger type transfer mould in this programme, comprise support plate, be positioned at the lower cavity die on support plate top and be positioned at the upper cavity die on lower cavity die top, die cavity is formed between lower cavity die and upper cavity die, reinforced chamber is provided with in the side direction of upper cavity die, described reinforced chamber communicates with described die cavity, core is provided with at the middle part of described die cavity, lower cavity die is vertically arranged with two push rods with core, the top of two push rods is all stretched in die cavity, the bottom of two push rods is all connected in the push pedal of a level, and described push pedal has the vertical free degree.
The beneficial effects of the utility model are as follows: owing to being vertically arranged with two push rods with core on lower cavity die, and the bottom of two push rods is all connected in the push pedal of a level, described push pedal has the vertical free degree, therefore after plastic parts moulding during discharging, push pedal moves upward, and then drive two push rods on push pedal top to withstand the bottom of plastic, plastic is symmetrically arranged with core, therefore, its power being applied on plastic is balance and uniform, plastic is being ejected in the process of die cavity, the stationarity of plastic discharging can be guaranteed, plastic surface is made not easily to produce scratch, thus ensure the quality of plastic.
Further, be provided with die block, die block has pilot hole in the periphery of described lower cavity die, upper cavity die is connected with vertical guide pillar, described guide pillar can be inserted in pilot hole when upper cavity die and lower cavity die matched moulds.When opening upper cavity die die sinking or matched moulds, by guide pillar and pilot hole, upper cavity die is played to the effect of motion guide.
Further, packing ring is fitted with at the inwall of described pilot hole.In order to reduce the rigid collision between pilot hole inwall and guide pillar, packing ring being set, reducing the wearing and tearing of guide pillar.
Further, be provided with counterdie seat board in the below of support plate, counterdie seat board top is provided with guide rod, and the middle part of push pedal has via hole, and described guide rod wears in the vias.When push pedal moves up and down, by guide rod and via hole, the motion of push pedal is played to the effect of guiding.
Accompanying drawing explanation
Fig. 1 is the structural representation of the utility model embodiment.
Detailed description of the invention
Below by detailed description of the invention, the utility model is described in further detail:
Reference numeral in Figure of description comprises: reinforced chamber 1, upper clamping plate 2, upper cavity die 3, die cavity 4, push rod 5, support plate 6, cushion block 7, counterdie seat board 8, push pedal 9, die block 10, guide pillar 11.
Embodiment is substantially as shown in Figure 1: reinforced chamber plunger type transfer mould on the present embodiment, counterdie seat board top is provided with the cushion block of ring-type, and push pedal is positioned at cushion block, and counterdie seat board top is provided with guide rod, and the middle part of push pedal has via hole, and guide rod wears in the vias.
Support plate is positioned at the top of cushion block, lower cavity die is positioned at the top of support, and lower cavity die is vertically arranged with two push rods with core, and the top of two push rods is all stretched in die cavity, the bottom of two push rods is all connected in the push pedal of level, and push pedal has the vertical free degree.
Upper cavity die has the vertical free degree, lower cavity die top is positioned at during upper cavity die matched moulds, die cavity is formed between lower cavity die and upper cavity die, reinforced chamber is provided with in the side direction of upper cavity die, reinforced chamber communicates with described die cavity, is provided with core, is provided with die block in the periphery of lower cavity die at the middle part of described die cavity, die block has pilot hole, is fitted with packing ring at the inwall of pilot hole.Upper cavity die is connected with vertical guide pillar, guide pillar can be inserted in pilot hole when upper cavity die and lower cavity die matched moulds.
This Shi Shizhong, upper cavity die and reinforced chamber are installed in the bottom of upper clamping plate, upper clamping plate, upper cavity die, lower cavity die, support plate, cushion block and counterdie seat board all have the vertical through hole that position is relative, in the vertical through hole of wherein counterdie seat board, cushion block and support plate, guide pin bushing is installed, be provided with long guide rod in the vertical through hole of upper clamping plate, upper cavity die and lower cavity die, this long guide rod can insert in guide pin bushing when upper cavity die matched moulds.
Above-described is only embodiment of the present utility model, and in scheme, the general knowledge such as known concrete structure and characteristic does not do too much description at this.Should be understood that; for a person skilled in the art, under the prerequisite not departing from the utility model structure, some distortion and improvement can also be made; these also should be considered as protection domain of the present utility model, and these all can not affect effect and the practical applicability of the utility model enforcement.The protection domain that this application claims should be as the criterion with the content of its claim, and the detailed description of the invention in description etc. record the content that may be used for explaining claim.
