Description

Plastic pallet mould secondary diagonal-slip core puller

Technical field

The utility model relates to a kind of plastic pallet mould secondary diagonal-slip core puller, belongs to plastics, mould applications.

Background technology

In the warehousing and logistics progress of various medicine foods, plastics chemical industry, raw material and paper mill etc., often use pallet.The kind of pallet is many, and wherein a kind of gusset of going up is dull and stereotyped, and it is III-shaped that lower web plate is; Have only forklift hole between the upper and lower gusset,, be specially adapted to paper such as paper plant, cigar mill and place smooth because last gusset is dull and stereotyped; Not damaged, it is III-shaped that lower web plate is, and places steadily.Lower surface at flat board is shaped on reinforcement, and both conservation reduced cost, and makes pallet intensity high again, and bearing capacity is good.But this pallet owing to should loose core to the forklift hole of pallet, to the reinforcement demoulding of last gusset lower surface, can't be realized the demoulding again when injection mo(u)lding.Prior art adopts twice injection moulding, is about to go up gusset and lower web plate injection moulding respectively, and welding fabrication so just increased production cost greatly, and production efficiency is low again.

Summary of the invention

The purpose of the utility model is in order to overcome the shortcoming of prior art, to provide a kind of employing secondary the tiltedly sliding mode of loosing core, make the pallet single injection-molded, and the demoulding being smooth, reduces production costs, the plastic pallet mould secondary diagonal-slip core puller of enhancing productivity.

The technical scheme of the utility model plastic pallet mould secondary diagonal-slip core puller is: comprise top board and base plate; Top board connects runner plate down; Heat flux plates is installed in the runner plate; Runner plate connects solid plate down; Mould pin and top board are installed on the base plate; Connect push rod on the top board; On the mould pin moving platen is installed; Moving die insert is installed in the moving platen, is constituted die cavity between moving die insert and the solid plate, the moulding pallet is arranged in the die cavity; Be shaped on forklift hole and reinforcement in the pallet; Intert long loose core slide block and short core-pulling slide block in the forklift hole, it is characterized in that the described length slide block of loosing core comprises long angled-lift splits down and long upward angled-lift splits, on the length match with reinforcement in the angled-lift splits top; The angled-lift splits bottom is shaped on long stopper slot on the length; Be equipped with long spacer pin on the angled-lift splits under long, long spacer pin matches with long stopper slot, and long angled-lift splits is down driven by the long oil cylinder of loosing core looses core; Described short core-pulling slide block comprises short angled-lift splits down and the short angled-lift splits of going up; On the weak point match with reinforcement in the angled-lift splits top; The angled-lift splits bottom is shaped on short stopper slot on the weak point; Be equipped with short spacer pin on the angled-lift splits under short; Short spacer pin matches with short stopper slot, and short angled-lift splits is down driven by the short core-pulling oil cylinder looses core.

The plastic pallet mould secondary diagonal-slip core puller of the utility model; After the die sinking, the long and short oil cylinder of loosing core drives long angled-lift splits down respectively and outwards slides with short angled-lift splits down and loose core, and long angled-lift splits down is with short down when angled-lift splits outwards skids off separately; Angled-lift splits is gone up angled-lift splits to lower slider with weak point on the length; The long angled-lift splits of going up is disengaged with reinforcement with the short angled-lift splits of going up, and after sliding into certain distance outside long angled-lift splits down and the short angled-lift splits down, upward angled-lift splits and reinforcement disengage fully for angled-lift splits and weak point length on; Contact with long stopper slot with the duration spacer pin; Short spacer pin contacts with short stopper slot, and long angled-lift splits down and short angled-lift splits down continue slidingly to drive the long angled-lift splits of going up and slide outward and loose core with the short angled-lift splits of going up outward, till the complete demoulding.The tiltedly sliding mode of loosing core of this programme secondary makes the pallet one-shot forming demoulding smooth, improves product quality and production efficiency, and saves cost.
